Point of care testing for blood glucose: utility and
reliability of blood glucose meters in out- patient
(diabetes clinics and community health camps) and in-
patient (nursing homes and hospitals) settings in semi urban
and rural India. Ramachandra Reddy, Srinivasa Diabetes
Centre, Mandya
Introduction.
Portable
hand held electronic meters for point of care and self home
blood glucose monitoring have been basic tools in diabetes
care in developed and developing countries over the last 4
decades. Despite continued improvements in technology and
reliability, practical problems (cost, training, quality
control, reproducibility, and ultimate clinical reliability)
remain, in the utility and penetrance of this essential
technology in the semi-urban and rural population of
developing countries like India. Also, there is a widely
prevalent belief among patients, especially the less
literate, and general practitioners, that the blood glucose
results “provided by the meter” are inferior to the
“laboratory reported” values, thereby inhibiting the use of
meters in self home and spot clinical blood glucose testing.
Aims.
To evaluate the real life reliability,
convenience and clinical utility of blood glucose meters in
an out patient diabetes clinic setting, in comparison with
simultaneously determined laboratory venous plasma glucose
values.
Methods.
400 T2DM
subjects were studied in a Diabetes Clinic (serving urban,
semi urban, and rural population) Fasting and
postprandial venous blood samples (400 + 400) were obtained,
and glucose analyses were done in parallel by: (a) blood
glucose meters (Contour - CON, and Ascentia - ASC) in the
clinic, and (b) chemistry analyzers in the laboratory
(GOD/POD method). Comparative analysis of the 2 strategies
of glucose measurement was done, with laboratory venous
plasma values as reference.

Results.
In FBG analyses > 15% variation was 8% and
7.5% for CON and ASC meters respectively. In PPBG
analyses > 15% variation was 17.5% and 18% for CON and ASC
meters respectively. Variations were greater in samples
with laboratory plasma glucose values > 400 mg/dl.
Conclusions
1. Portable
hand held electronic meters for point of care (Diabetes
Clinic) blood glucose monitoring and immediate management
planning are very useful tools in diabetes care in
developing countries, especially in the semi-urban and rural
populations.
2. This
strategy is reliable, practical, cost effective (savings on
time, travel and other expenses) in socially relevant
diabetes care.
3. The
prevalent belief among patients and general practitioners,
that the blood glucose results “provided by the meter” are
inferior to the “laboratory reported” values, is incorrect.
4. In
reference to laboratory determinations, blood glucose values
generated by the meter in relatively more variable for PPBG
(15 to 20%), especially higher values, than FBG. Thus,
diagnosis of IFG and IGT will not be significantly affected
by the meter approach, thus emphasizing their reliability in
screening community health camps etc.
5. Of
course, very meticulous methodology (at every minute step)
in blood glucose testing my meter is crucial.
Prevention of progression of diabetic nephropathy.
Lakshminarayan V, Venkat Rao S. Sreehari Diabetes
Foundation, Mysore.
Diabetic nephropathy is one of the fatal long term
complication of T2 DM. The single most important step to
interfere with its emergence and progression is to monitor
the patients regularly for the presence of albuminuria and
to focus on intensified treatment.
The earliest clinical evidence of nephropathy is the
appearance of low but abnormal levels of albumin in urine
referred to as microalbuminuria (MAU). Valsartan, a highly
selective ARB, has been shown effective in reducing BP and
albuminuria. The effect of this ARB in reducing BP and
urinary albumin excretion rate (UAER) and its safety has
been investigated in Indian patients of T2 DM with or
without HTN.
Forty microalbuminuric T2 DM subjects (29 M, 11F) aged 39-69
years, visiting as outpatients of Shreehari Diabetes
Foundation, participated in the study. At baseline 23
patients had HTN and 17 were without HTN. Baseline data were
obtained on hematology, biochemistry, HbA1c, lipid profile,
UAER,BP and ECG. Valsartan 80 mg/day was started with upward
titration to 160 mg/day after 4 weeks, with further addition
of diuretic HCTZ 12.5 mg/day at end of 8 weeks.
The percentage reduction in UAER was more after 8 weeks
(30-39%), compared to 16 weeks (25-26%), indicating that
treatment with valsartan shows an effect an MAU, as early as
8 weeks, in both normo and hypertensive diabetics. The
proportion of patients returning to normoalbuminuria status
after 8 weeks of valsartan treatment was 13-15% and 9% after
16 weeks. The lesser reduction in UAER after 16 weeks may
probably be due to progression of disease state in some
patients. The percentage of normotensive patients
significantly increased from 38-44% to 50-69% after 8 weeks
and 78% after 16 weeks, signifying that valsartan has good
efficacy in treating HTN in T2 DM. No adverse events were
reported in any patient treated with valsartan for 16 weeks.
Laboratory investigations such as hematology, blood
chemistry and lipid profile were within normal limits in
patients treated with valsartan for 16 weeks, signifying
that no adverse changes were observed with the drug.
Pharmacovigilance: The Importance of Reporting an Adverse
Drug Reaction.
Akku Shyam Prasad Dept. of Pharmacology, Kamineni
Institute of Medical Sciences, Narketpally, Nalgonda.
Aim.
The presentation aims at bringing about
awareness amongst clinicians about the National
Pharmacovigilance Programme and highlights the importance of
reporting an adverse drug reaction.
Abstract.
India being
the global hub for clinical research is being targeted by a
large number of multinational drug companies for conducting
clinical trials for new drugs. The need hence arises to
monitor these drugs so as to ensure a safer health care
system. Once put onto the market, a medicine leaves the
secure and protected scientific environment of clinical
trials and is legally set free for consumption by the
general population. It is essential that new and medically
still evolving treatments are monitored for their
effectiveness and safety under real-life conditions post
release. Information about rare but serious adverse drug
reactions, chronic toxicity, use in special groups (eg.
pregnant women, children, elderly) and drug interactions is
often incomplete or not available. Certain adverse drug
reactions may not be detected until a very large number of
people have received the medicine. National
Pharmacovigilance Programme initiated by Central Drugs
Standard Control Organization (CDSCO) is one of the
important post-marketing tools to ensure the safety of
pharmaceutical and related health products.
Pharmacovigilance is defined as the detection, assessment
and prevention of adverse drug reactions in humans.
The purpose of the programme is to collect data, analyze it
and use the inferences to recommend informed regulatory
interventions, besides communicating risks to healthcare
professionals and the public. The data so collected will
generate broad based ADR data on the Indian population and
share the information with global health-care community
through WHO-Uppsala Monitoring Centre, Sweden. The
clinicians of today bare more responsibility towards the
society than ever before and play a key role in ensuring a
safer health care system by reporting an adverse drug
reaction to the National Pharmacovigilance Programme centre.
The clinician is expected not only to report an adverse drug
reaction but also any suspected drug reaction or
interaction.
It throws light on various issues such as: What to report?
Who can report? Where to report? What happens to the
information submitted? An Adverse Drug Reaction Form has
been set up so at to make data analysis simpler.
The importance of reporting an ADR- Example: Cerivastatin
which was first approved as a lipid-regulating agent in
1997. By 2000 a total of 549 cases of rhabdomyolysis
associated with cerivastatin use had been reported to the
WHO Collaborating Centre for International Drug Monitoring,
Uppsala, Sweden. In November 1999 in the United States, and
in March 2000 in Canada, prescribing information was changed
to include a contraindication for the combined use of
cerivastatin andgemfibrozil, another lipid-regulating
medicine. On 8 August 2001, the manufacturer voluntarily
withdrew cerivastatin from the market on the grounds of an
increased risk of rhabdomyolysis, particularly when used in
combination with gemfibrozil.
The terminology pertaining to side effects, adverse drug
reactions, adverse drug events, signal need some explanation
and the programme expands these so as to have a clear
picture.

IDMPS Study
Management of Hyperglycemia in Type 2 Diabetes Patients in
India: Results from IDMPS Year 1.
Ramachandran A, Snehalatha C. India Diabetes Research
Foundation, Dr A Ramachandran’s Diabetes Hospitals, Egmore,
Chennai, India.
Objective.
International Diabetes Management Practices Study (IDMPS), a
5-year, multinational observational study, assesses the
current therapeutic management of diabetes in different
parts of the world and evaluates the compliance with
international guidelines to improve the quality of care for
patients.
Methods.
One-year data were collected from Indian type 2 diabetes
mellitus (T2DM) patients (>18 years) during a 2-week
cross-sectional period.
Results.
The first cross-sectional period of the study assessed 1639
T2DM patients (56.5% males; mean age of 54.1±11.8 years).
Their mean BMI was 26.7±4.6 kg/m2 (n=1606)
and mean diabetes duration was 8.0±6.5 years. At
least one diabetes late complication was seen in 47.8%
patients, of which 89.5% had microvascular complications and
42.1% had macrovascular complications. Only 1.3% patients
were treated with diet+exercise, 5.9% with insulin alone
(basal, basal+prandial, prandial, premix and others), 23.7%
with insulin+oral antidiabetic drugs (OAD), and 69.1% with
OAD alone (glinidines, biguanides, thiazolidinediones,
alpha-glucosidase inhibitors, sulphonylureas, and
biguanides+sulphonylureas). The median frequency of
laboratory monitoring for HbA1c was
2.0 in past 2 years (n=809), that for FBG was 6 per year
(n=1619), and that of self-monitoring for FBG+PPG was 2.0
per week (n=310). Median HbA1c was
7 and only 256 (32.1%) patients reached the target value of
HbA1c<7%.
Also, median FBG was 121 mg/dL and only 353 (23.3%) patients
reached the optimal FBG=100 mg/dL.
Conclusion.
Target value of HbA1c was seen in 32.1% T2DM patients. This
was in agreement with the results in other countries.
Efforts must be taken to improve the outcome by better
monitoring and treatment adherence.
Glycemic Control in Insulinized Type 2 Diabetes Patients in
India: Results from IDMPS Year 1.
Ramachandran A, Snehalatha C. India Diabetes Research
Foundation, Dr A Ramachandran’s Diabetes Hospitals, Egmore,
Chennai, India.
Objectives.
International Diabetes Management Practices Study (IDMPS), a
5-year observational study, assesses the current therapeutic
management of diabetes worldwide and evaluates compliance
with international guidelines.
Methods.
One-year data were collected from Indian type 2 diabetes
mellitus (T2DM) patients.
Results.
Of 1639 T2DM patients, 485 (29.6%) were insulinized, with
5.9% on insulin alone and 23.7 % on insulin+oral
antidiabetic drugs (OAD). In insulinized patients (55.3%
men), mean age was 55.0±12.4 years, mean BMI 26.4±4.6 kg/m2,
mean disease duration 11.2±7.1 years and mean duration of
insulin treatment 3.5±4.2 years. The most common insulin
regimens were premix+OAD, premix alone, and basal+OAD. The
mean insulin dose (IU/day) was 17.8±10.1, 32.3±15.5,
39.4±10.4 and 46.1±18.4 for patients receiving 1, 2, 3 and
>4 doses, respectively. HbA1c was
tested in 60.6% (median frequency: 2 in previous 2 years,
mean HbA1c:
8.0±1.5% [n=287]) and 68 (14.3%) patients reached HbA1c<7%.
Median frequency of laboratory testing of FBG was (median)
per year, mean FBG was 147.5±62.9 mg/dL (n=435), and 98
(22.5%) patients reached FBG<100 mg/dL. Overall, 235 (48.7%)
patients reached the glycemic target. BG was self-monitored
by 151 (31.1%), while 110 (22.7%) patients self-adjusted
insulin. Patients who self-monitored BG had better glycemic
control than those without self-monitoring (HbA1c<7%:
29.4% vs 19.6%, c2 =2.27,p=0.023 FBG<100 mg/dL: 25.7% vs
21.1%, (NS)). Patients who did/did not reach glycemic target
differed significantly in terms of owning a glucometer and
self-monitoring of BG.
Conclusions.
Nearly 50% of insulinized Indian T2DM patients have good
glycaemic control. Self monitoring is rare and their daily
insulin dose was low. Self-monitoring of BG was associated
with better glycemic control.

A comparative study of association of Psycho-Social Stress
in Diabetics Vs Non-diabetics.
Vinod MR, Narahari MG, Basavana Gowdappa H, Prabhakar
AK. JSS Medical College, Mysore.
Background.
The association of psycho-social stress in diabetic patients
has been widely documented in the literature. However, there
is little published data from the Indian subcontinent on the
association of psycho-social stress in diabetes.
Aims
& Objectives.
The
present study aims at studying the association of
psychosocial stress in diabetes using a validated
questionnaire developed by the Indian Council of Medical
Research (ICMR).
Methods.
The
study included 100 diagnosed cases of diabetes and an equal
umber of controls matched on age and sex attending the out
patient department of JSS Medical College Hospital, Mysore.
The administered questionnaire encompassed various
components viz; interpersonal relationship, liability,
financial constraints, marital issues and health related
problems. Also, it included a separate questionnaire related
to stressful life events. The four digit scale was utilized
for measuring the stress level for each of the component
included in the study. The cut off points for level of
stress was derived and tested for its reliability and
validity. The cut off levels recommended by ICMR was adopted
for classification of stress level. The factor analysis was
carried out to derive major factors related with stressful
events. A total of six factors were derived. The relative
risks of stress was estimated for both the sexes and also
mean standard deviation for each of the factors were
estimated for cases and controls and compared.
Results.
A total
of 28 subjects had stress with 26 in the diabetic cases and
only 2 in the controls providing an overall relative risk of
17.21 with confidence band of 3.96-74.84. The results
indicated that diabetic females had a higher stress levels
(41.3%) as against males (13%). In females the relative risk
was very high 15.48 (confidence band 3.39-71.76). The
analysis of stress related to life events indicated that the
total relative risk in diabetics was 9.71 (CI =4.41-21.38),
for females it was 20.36 (5.49-75.43) and males 5.5
(CI=2.01-15.06) respectively. The detailed results of factor
analysis will be presented in the poster.
Conclusion.
This
pilot study has shown a greater association of psycho-social
stress in diabetics and the stress levels are comparatively
higher in females.
Determinants of the quality of life among diabetic subjects
in Kerala, India.
Ron Thomas Varghese, Rekha Salini, Pradeep Abraham,
Reeshma KK and Vijayakumar K. Department of Community
Medicine, Government Medical College, Thiruvananthapuram,
Kerala.
The number of Indian
diabetic subjects is projected to be 57 million in 2025. Due
to the large number of people involved and its associated
complications, the disease warrants urgent attention.
Studies have proved that the prevalence of diabetes is high
in the state of Kerala. Of the few studies are carried out
in India considering the magnitude of the disease here most
pertains to the quantitative estimates of the disease. The
virtual absence of literature on quality of life of Indians
with diabetes has prompted us to assess quality of life and
its determinants in our subjects.
Objectives. To estimate the level
of quality of life (QOL) and its determinants among subjects
having diabetes in Thiruvananthapuram, Kerala, India.
Research Designs and Methods.
We conducted a cross sectional
study on 200 subjects who attended the Diabetes clinic,
Medical College & Institute for Diabetes, Thiruvananthapuram.
Univariate & Multivariate analysis of data collected by
interview method using a questionnaire (DQOL-DCCT) were done
using odds ratio & chi square test for significance. Those
who achieved score above 60% were presumed to have good QOL.
Multiple Logistic Regression analysis was done following a
forward step wise method of elimination.
Results.
62% subjects had good QOL. Following factors were found to
be significantly associated with QOL by Univariate analysis:
Satisfaction in social relationships & friendships, time for
management of diabetes, feeling of physical illness, worry
of diabetic complications, satisfaction with treatment, male
gender, occupation involving moderate physical work, better
education, mixed diet, diet & exercise as treatment
modality, physical activity, family history of diabetes,
regular consultation, having diabetic friends, better sex
life, no urgency of micturition due to diabetes, less
frequently complaining about diabetic condition.
Conclusion. Multivariate analysis
established that satisfaction in social relationships &
friendships, time set apart for management of diabetes,
feeling of physical illness, worry of diabetic
complications, contribute to major variation in QOL and
accounted for 46.5% variation of QOL in men, these factors
coupled with treatment satisfaction accounted for 65.4%
variation in QOL in women.
Effects of Yoga on psychologial well-being and
BMI. Madhu K and Sridhar GR on behalf of Yoga and
Diabetes Research Group, Institute of Yoga and Consciousnes, Visakhapatnam.
We evaluated the effect of yoga practice on clinical and
psychological outcomes in subjects with type 2 diabetes
mellitus (n:38) in a 40 day yoga camp at the Institute of
Yoga and Consciousness, Visakhapatnam. The 40 day yogic
practices were overseen by trained yoga teachers. At the end
of the study, there was a reduction of body mass index
(26.514+/-3.355 to 25.771+/-3.40; p<0.001), anxiety
(6.20+/-3.72 to 4.29+/-4.46; p<0.05) and improvement in
total general well-being (48.6+/-11.13 to
52.66+/-52.66+/-12.87; p<0.05). In conclusion participation
of subjects with T2DM in yoga practice for 40 days resulted
in reduced BMI, improved well-being and reduced anxiety.
Psychological distress in south Indian women
with polycystic ovary syndrome.
Sundararaman PG, Shweta, Sridhar GR. Endocrine and
Diabetes Center, Visakhapatnam.
Polycystic ovary syndrome (PCOS), is now recognized to be
associated with insulin resistance and attendant metabolic
complications. It leads to psychological distress. There are
no Indian studies on psychological stress in women with PCOS.
We studied ninenty nine women who presented with PCOS to the
Endocrinology clinic of Govt Hospital for Women and
Children, Chennai. They were administered Goldberg’s GHQ 28
(General Health Questionnaire) to assess psychological
status, along with clinical, hormonal and ultrasound
evaluation Fifty four percent had a GHQ28 score >8 Among
them 38% had a family size<4, 72% had obesity, 70% had
hirsutism, 72% had a waist circumference >88cm and 69% had a
F/G score>4. All these variables were statistically
significant; p<0.05 using Chi-square test. In summary women
presenting with PCOS had increased psychological distress,
which was related to smaller size of family, and more severe
physical manifestations of the condition.

Continuing Learning : Revisiting Glycaemic Pathway in
patients admitted for CABG.
Menaka R, Manjunath A, Narendra BS, Bhattacharyya
A. Department of Diabetes and Endocrinology, Manipal
Hospital, Bangalore.
Aims
and Objectives.
Good
glycaemic control is an important determinant of outcome
after CABG. We had shown that a structured plan (Glycaemic
pathway) of managing Diabetes involving specialist in
patients undergoing CABG is worthwhile. Based on the
findings we have modified our pathway in order to improve
glycaemic control in similar patients.
Materials and Methods.
This cohort
constitutes first 50 patients completing ‘Modified Glycaemic
pathway’. In comparison to our earlier pathway, we had
titrated the scale on IV/SC insulin in order to achieve
better glycaemic control.
Results.
Glycaemic
control while on IV insulin was good in 60%, suboptimal in
37% and poor in 3% of patients in the modified glycaemic
pathway in comparison to earlier study (61, 37 and 2%
respectively). Similarly while on SC insulin control was
good in 63% of patients, fair in 36% and poor in 1% as
compared to 53, 45 and 2% before modification of the
pathway. As anticipated, the frequency of hypoglycaemia was
higher but they were all mild and managed easily. All were
discharged on Insulin. There were no mortalities both before
and after modification of pathway.
Conclusion.
We are happy
to show clearly the benefit of a structured intervention in
glycaemic management of patients undergoing CABG. Also the
current data documents the need to review one’s own
protocols to find out the scope of improvement in line of
continuing medical education that can provide better patient
care.
Continuous subcutaneous insulin infusion for type 2 diabetes
mellitus in pregnancy.
Muthukrishnan J, Harikumar KVS, Verma A, Ugale M1,
Modi KD. Dept of Endocrinology, Medwin Hospital,
Hyderabad. 1 Kirloskar Hospital, Hyderabad.
Objective.
To present
two pregnant women with poorly controlled Type 2 Diabetes
mellitus on multiple dose insulin injections (MDII) managed
successfully on Continuous subcutaneous insulin infusion (CSII).
Methods.
Two women
with pregnancy complicated by Type 2 Diabetes mellitus were
initially managed on MDII. They were switched over to CSII
in view of poor glycemic control and frequent hypoglycemia
during the third trimester.
Result.
In both
cases, satisfactory improvement in glycemic control without
hypoglycemia was achieved. Both delivered a healthy child
without macrosomia or neonatal hypoglycemia. Details of
clinical and glycemic profile are presented in table 1.
Conclusion.
Intensive
regimen with MDII often fails to achieve glycemic targets
and result in frequent hypoglycemia in women with high
insulin requirements. Use of CSII is effective mode of
therapy in such cases.

A study on lipoprotein pattern in case of Diabetes
Mellitus type 2 under treatment of various hypoglycemic
drugs. Prabhakar PK1, Mukesh Doble A1,
Uday Kumar B2 1Department of
Biotechnology, Indian Institute of Technology Madras,
Chennai. 2Indira Gandhi Institute of Medical
Sciences, Sheikhpura, Patna.
Background.
Atherosclerosis and coronary heart disease (CHD) are the
major vascular complications of diabetes and they have
enormous impact on the health of those affected. The present
study was carried out to determine the effect of different
therapies (oral hypoglycemic drug (OHD) and insulin) on the
lipid profile of diabetic patients. There are reports that
in the case of diabetes mellitus the lipid profile becomes
irregular and are associated with atherosclerosis and CHD.
Method.
For the
present study 60 diabetic patients were selected
randomly in the age group of 35-55 years, 30 of them are
oral drug users and 30 use insulin. 30 healthy persons of
comparable age were selected as control. The fasting plasma
sugar was estimated by O-toluidine method, serum cholesterol
and HDL-c was estimated by cholesterol oxidase-peroxidase
method and serum triglyceride was estimated by
glycerol-3-phosphate oxidase method. LDL-c and VLDL were
estimated by using Friedelwald’s formula.
Results.
Fasting
plasma glucose level was significantly higher in both the
insulin and OHD users in comparison to the control group.
But there was no significant difference between insulin and
OHD users. The total cholesterol, triglyceride, LDL-c and
VLDL-c of diabetic patients were significantly higher in
both insulin user and OHD users when compared to the
control. Whereas, the HDL–c was significantly lower in
diabetic patients when compared to the control.
Conclusion.
Type 2
diabetic patients who were on insulin therapy had slightly
better lipid profile than those who were on oral
hypoglycemic therapy. Lipid abnormality may be the result of
the unbalanced metabolic effect of diabetes. Control of
hyperglycemia does moderately improve the lipid profile in
diabetic patients. Lipoproteins fractions (HDL-c, LDL-c,
VLDL-c and Cholesterol) of the diabetic patients were found
to be highly disturbed as compared to the control group and
they showed a trend of developing atherogenic states in the
future.
Comparison of effects of Glimepiride on blood sugar levels
between male and female sexes.
Pramod JM, Prasanna Kumar KM, Shivamurthy MC,
Niveditha. MS Ramaiah Medical College, Bangalore.
Introduction.
Glimepiride
is a long acting sulfonylurea with additional
extra-pancreatic effects. The incidence of hypoglycemia with
Glimepiride is significantly lower than other Sulphonylureas.
Aim.
To compare
the effects of Glimepiride on blood sugar levels between
male and female sexes.
Materials and Methods.
The study
group consisted of 35 patients with type 2 diabetes mellitus
who were on treatment with Glimepiride for a minimum of one
month. The study group consisted of 17 males and 18 females
aged between 25 to 65 years. Study group was started on once
daily Glimepiride with individualized dose (dose with which
the FBS was controlled i.e. FBS <140mg%). The glycaemic
control was assessed by fasting blood glucose levels
measured at the end of each week of treatment for three
weeks.
Results.
The mean
baseline FBS levels between male and female subjects did not
differ much and was not statistically significant (p=0.144).
The mean FBS level at the end of each week of treatment for
three weeks between male and female subjects did not differ
much and was not statistically significant (p value for
first, second and third week being 0.235, 0.237 and 0.389
respectively).
Conclusion.
The study
has shown that there is no difference in the effects of
Glimepiride on blood sugar levels between male and female
sexes. This is consistent with the finding that there are no
differences between males and females in the
pharmacokinetics and pharmacodynamics of Glimepiride.
Evaluation of effect of dose and duration of treatment with
metformin on serum vitamin B12 levels in type 2
diabetic patients.
Harsha KP, Prasanna Kumar KM, Sanjay Reddy,
Shivamurthy MC, Niveditha . MS Ramaiah Medical College and
Teaching Hospital Bangalore.
Introduction.
Metformin
induced impaired vitamin B12 absorption leading to fall in
serum cobalamin levels has been described in literature as
early as 1971. Approximately 10% of patients and in some
studies 30% of patients on metformin therapy developed
metformin related cobalamin deficiency. The risk of
cobalamin deficiency is comparatively more among patients
with vegetarian diet than in non-vegetarians
Objectives.
To evaluate
the effect of dose and duration of treatment with metformin
on serum vitamin B12 levels in type 2 diabetic patients.
Materials and Methods.
By using
available database of patients with type 2 diabetes mellitus
lists of all patients with type 2 diabetes mellitus on
metformin monotherapy or insulin and metformin was made.
These patients will be asked to visit the hospital by
contacting them through telephone. A total of 40 patients
were chosen. By using a pilot tested proforma details were
collected on demographic data, dietary habits. Duration of
treatment with metformin and dose of metformin was also
noted. All patients will undergo routine investigations
which include RBS, PPBS, and HbA1c.
After taking their informed consent, 5 ml of blood will be
collected and sent to the central laboratory for serum
vitamin B12 estimation. Vitamin B12 estimation was done
using a recently developed method called as active vitamin
B12 assay.
Results.
Our results
showed that mean Vitamin B12 levels among patients on dose
of less than 1gm/day was 57.8pcm/dl and was 40.4 pcm/l in
patients on dose more than 1gm/day. The mean B12 levels were
39.7, 54.3 and 75.9pcm/l in duration of treatments <2 yrs,
3-5yrs and >5yrs respectively.
Conclusion.
Our study
shows that dose of metformin did not show any significant
relationship with serum vitamin B12 levels while there was a
progressive increase in serum B12 levels with increasing
duration of therapy.
Sitagliptin added on to the ongoing anti-diabetic therapy:
An initial experience.
Patel HS1, Navneet Wadhwa2
Diabetes Education Management and Research Centre, Jabalpur.
Introduction.
Sitagliptin
a highly specific and potent inhibitor of DPP-4 enzyme, is a
novel approach for the management of type II diabetes. It
enhances the incretin levels by 2-3 fold to improve both
alpha and beta cell dysfunctions simultaneously resulting in
the physiological control of plasma glucose levels.
Sitagliptin, the only DDP-4 inhibitor approved by US FDA is
available in India since April 2008.
Methods.
Sitagliptin
was added in 25 patients uncontrolled with ongoing
anti-diabetics therapy. The clinical data record was
retrospectively evaluated and analysed for the change in the
fasting and post prandial plasma glucose levels at a follow
up visits at three and six weeks. The improvement in the
plasma glucose levels were statistically analysed for the
absolute reductions in fasting and post prandial plasma
glucose and across subgroups on the basis of the age, BMI
and duration of diabetes.
Results.
Six weeks of
Sitagliptin as an add on therapy in 25 patients (19 male, 6
female) had significant improvements in the fasting and post
prandial plasma glucose levels. The patients were on multi
drug therapies including metformin, sulponylurea, insulin,
pioglitazone and alpha glucosidase inhibitors. The mean age
was 50.76 years (36-67 years), mean BMI 25.11 kg/m2 (19.8-29.17
kg/m2)
and mean duration of diabetics 6 years (3-16 years). Mean
HbA1c at the Sitagliptin initiation was 9.27% (7.8%-12.7%),
with none of the patients within the glycemic target of
HbA1c <7%. Majority of the patients had a family history of
diabetes (64%), compliance to diet (72%), exercise (72%) and
had associated comorbid conditions like hypertension,
retinopathy and renal impairment (56%).
At week 3 and 6, sitagliptin led to highly significant
(p<0.001) reductions in both fasting and post prandial
plasma glucose. At week 6, as compared to the baseline, the
plasma glucose levels consistently improved with mean
decrease of 52 mg/dl (31% reduction) and 102mg/dl decrease
(37% reduction), in both fasting and post prandial plasma
glucose, respectively. The subgroup analysis for the
reductions in both fasting and post prandial plasma glucose
across age groups (= 50 and < 50 years, FPG p=0.363, PPG
p=0.16 ), BMI (= 25 and < 25 kg/m2 ,
FPG p=0.664, PPG p=0.976) and duration of
diabetes ( = 6 and < 6 years, FPG p=0.676, PPG p=0.81),
demonstrated similar results across the subgroups.
Conclusions.
Sitagliptin
100mg once daily when added to the ongoing anti-diabetic
therapy resulted in effective and highly significant
reductions in both fasting and post prandial plasma glucose
at 3 weeks and 6 weeks. Sitagliptin was consistently
effective across subgroups of patients defined by age, BMI
and duration of diabetes. This initial experience is
expected to be further strengthened for the glycemic control
and treat to target (HbA1C < 7%) comparative analysis by
repeat HbA1c estimation at the end of 12 weeks.
The observations of this study are similar and consistent
with the existing trials results and the recently presented
data at ADA 2008, San Francisco.

Diabetes-Endocrinology and Ophthalmology, Manipal Hospital,
Bangalore.
Aims
and Objectives.
Thyroid
associated orbitopathy (TAO) is seen less frequently in our
country but can have sight threatening consequences. We
report two cases of Rosiglitazone induced TAO. CASE 1
55-yr-male with T2DM
on Glibenclamide and Metformin, started on Carbimazole for
Graves’ disease 6mths back, referred with TAO. He was
started on Rosiglitazone (TZD-Thiazolidinediones) for
uncontrolled diabetes 3mths back. On examination he had B/L
proptosis with eyelid retraction and exposure keratitis.
Extraocular movements were restricted with visual
compromise. He was euthyroid. CT scan confirmed TAO. He was
started on IV methylprednisolone and without improvement and
underwent orbital decompression. CASE 2 46yr-doctor
presented with prominent eyes 2mths after diagnosis of T2DM.
Graves’ disease 5yrs back was treated with Carbimazole for
6mths. He did not have ophthalmopathy or dermopathy and was
happy with remission. CT scan of the orbit confirmed TAO, he
was euthyroid. Penny dropped with medication history – given
Rosiglitazone for Diabetes. He responded to stoppage of TZD
along with a course of oral Prednisolone for 4wks.
DISCUSSION TZD is known to increase SC fat. Expression of
TSH-receptor and adipogenesis in orbit is well documented in
Graves’ disease. PPAR-ã activation by TZD has been shown to
stimulate functional TSH-receptor expression and to induce
recruitment and differentiation of orbital fibroblasts into
mature lipid-laden adipocytes.
Conclusion.
TZD
exacerbates TAO; this should be kept in mind when selecting
treatment for diabetic patients with Graves’ disease.

Glycated albumin at different stages of diabetic
nephropathy in India. Vijay Viswanathan, Satyavani K,
Priyanka Tilak MV Hospital for diabetes and diabetes
research centre, Royapuram, Chennai.
Aims.
Glycated
Haemoglobin (HbA1c) which is an index of long term glycaemic
control in diabetic patients is measured in majority of
patients world wide. Glycated albumin (GA) is useful for the
evaluation of short term glycaemic control (2 weeks) in
patients with diabetes. The aims of this study were to
assess the GA levels at different stages of diabetic
nephropathy and to derive a normal cutoff value for glycated
albumin in this population.
Methods.
A total of
197 subjects (M:F; 109: 88) were selected for this study and
were divided into three groups based on their renal function
and compared with a non diabetic control group. The groups
were as follows; group1 (control) n = 50, group2 (normoalbuminuria)
n = 42, group 3 (Microalbuminuria) n = 55, group 4 (proteinuria)
n = 50. GA was measured by enzymatic procedure using the
Lucica GA – L kit (Asahi Kasei Pharma Corp, Japan).
Results.
The normal
cutoff value for GA was derived using control group and it
was found to be 15% (range 7-17%). GA % was significantly
higher in diabetic patients at different stages of diabetic
nephropathy compared to non diabetic control group [cont
12.9±1.8, normo 20.8±5.8, micro26.1±8.6, macro23.5±83).
Microalbuminuric patients had significantly higher GA levels
than normoalbuminuric patients (p<0.05) Proteinuric subjects
had slightly lower GA levels compared to micro group but it
was not statistically significant.
Conclusion.
GA was found
to be a better marker for evaluating short term glycemic
status among diabetic patients with different degree of
renal impairment.
Insulin resistance at different stages of diabetic kidney
disease in India.
Vijay V, Satyavani K, Priyanka T. Diabetes Research
Centre and MV Hospital for Diabetes, Royapuram, Chennai.
Objective.
Insulin
resistance (IR) is associated with diabetes and
cardiovascular disease. Many studies showed that IR is
present in chronic renal failure and evidences suggest that
IR can also occur in early stages of renal disease. There is
paucity of data from Indian population hence this study was
planned with the aim of defining the degree of Insulin
resistance among different stages of diabetic nephropathy.
Subjects and Methods.
A total of
160 subjects (M:F;89:71), were selected for this study and
divided into3 groups based on their renal function and
compared with control group. The groups were:group1
(control) n=32, group2 (Normoalbuminuria) n=26, group3 (Microalbuminuria)
n=59 and group4 (Macroalbuminuria) n=43. Subjects on insulin
treatment were excluded. Insulin was estimated by
chemiluminescence method. Biochemical investigations were
done by enzymatic procedures. Insulin resistance was
calculated HOMA method. The normal cut off value for IR
(2.4) was derived using mean+2SD of controls.
Results.
There was no
significant difference between the study groups with respect
to age, BMI and duration of diabetes. Mean IR increased
significantly with decreasing renal function (NGT:1.30±0.53;
Normo: 4.0±2.7; Micro: 5.81±4.1; Macro: 8.0±5.1,p<0.04).
Larger percentage of subjects had insulin resistance (=2.4)
at different stages of impaired renal function (Normoalb:
69.2%; Microalb: 76.2%, Macroalb: 90.6%) compared to normal
(3.12%). Mean IR increased with the deteriorating renal
function as assessed by eGFR, (eGFR>90: 5.8±4.2; eGFR60–89:
6.5±4.8; eGFR30–59ml/min:7.5±4.5).
Conclusion.
This study
showed that as DN progresses, IR is aggravated and it may be
in addition to other associated factors, possibly accelerate
the decline in renal function. The relationship between
several potential modifiable mechanisms which are said to be
contributing in worsening of IR among DN is yet to be
defined in our population.

Science, Pilani, Rajasthan.
Objective.
To study
polymorphism of ARNT gene so as to ascertain its correlation
with resistance to diabetes in Raika community.
Methods.
Study was
conducted in 57 individuals from the Raika community and 75
people of Non-Raika communities. DNA from blood samples was
isolated by using the procedure of Hammond et al with minor
modifications. DNA was visualized on 0.8% agarose gel for
quality check and was further quantified and qualified by
taking optical density at 260 and 280 nm on a UV
spectrophotometer. Genomic DNA was genotyped using PCR
amplification and restriction fragment length polymorphism.
Results and Discussion.
The mean age
of Raika individuals was 41.14±17.92 and that of non-Raika
individuals was 46.93±12.37. The anthropometric and clinical
parameters, which are markers for risk for type 2 diabetes,
were seen better in the Raika community. The frequency of GG
allele in Raika community was 0.92 and in Non Raika
community was 0.94. Similarly, the distribution of AG allele
in Raika community was 0.08 and in non Raika community 0.06.
Conclusion.
Present
study concluded that the polymorphism studied has same
frequency distribution in both Raika and non-Raika people
with or without diabetic conditions. As explained by other
studies throughout the world it is once again established
that diabetes is not totally environmental and genes play
their role in its etiology. The negative results of the
present study have excluded atleast one gene from this list
and lead the way to explore several genes not with a
targeted gene approach but with a targeted approach towards
genes.

gene, with South Indian type 2 diabetes.
Thanigaivelan K, Ezhilarasi K, Shila S, Parthiban M,
Satyavani K, Vijay Viswanathan. Biochemistry Department, MV
Hospital for Diabetes and Diabetes Research Centre, Chennai.
Background.
Alpha-2-Heremans-Schmid Glycoprotein (AHSG), coded by AHSG
gene, is a natural inhibitor of the insulin receptor
tyrosine kinase, and plays a significant role in decreasing
the insulin sensitivity.
Aim.
To study the
association of Thr256 Ser polymorphism in AHSG gene (exon
7-chr 3q27) with South Indian type 2 diabetes.
Material and Methods.
A total
of 50 type 2diabetic patients attending
outpatient department of MV Hospital for diabetes, Chennai
during May to July 2008 were included in this study. 50
hospital staff that were not having T2DM served as control
population. Genomic DNA was isolated from the blood samples
of these subjects and subjected to PCR amplification using
the primer sequence
5’GTAAGGCAACACTCAGTGA3’-Forward primer
5’TCATCACTGCCATGTCTAG3’-Reverse primer
Amplified products were subjected to RFLP using restriction
enzyme SacI , which cleaves at the site
5’GAGCT*C3’
3’C*TCGAG5’
The appearance of bands, corresponding to base pair of 731
in agarose gel electrophoresis was looked for. This
represents the Single Nucleotide Polymorphism (SNP) of
Thr 256 Ser in AHSG gene.
Results.
4% of normal individuals and 40% of T2DM
patients of South India were having nonsynonymous coding
polymorphism of AHSG gene (Thr 256 Ser). There is
significant association of this polymorphism with T2DM.
Conclusion.
This study
suggests that AHSG gene (Thr 256 Ser) polymorphism is
associated with type 2 diabetes of South Indian population.

of Endocrinology, Medwin Hospitals, Nampally, Hyderabad.
2Department of Laparoscopic Surgery, Kirloskar
Hospital, Bashir Bagh, Hyderabad.
Objective.
To determine
the efficacy of a novel procedure consisting of ileal switch
(transposition of a segment of ileum into proximal jejunum)
and sleeve gastrectomy on glycemic control and other
constituents of metabolic syndrome in type 2 diabetes
patients.
Methods.
In this
ongoing study, five patients underwent laparoscopic
procedure of sleeve gastrectomy coupled with transposition
of a segment of ileum into proximal jejunum. All patients
had diagnosis of diabetes for more than 3 yrs with poor
control despite use of oral hypoglycemic agents (OHA) and
insulin. The primary outcome is remission of diabetes
(HbA1c<7% without requiring OHA) and secondary outcomes are
change in weight, blood pressure, insulin resistance and in
parameters of metabolic syndrome.
Results.
Out of 5
patients who underwent surgery, we report the six month
follow up data of two patients, and 2 month follow up of
another 2 patients. The first two patients had remission in
diabetes and other two showed significant decrease in
requirement of OHA. HbA1c dropped from 9.9% to 7% in 1st patient
and from 15.8% to 5.8% in 2nd patient.
All 4 patients showed remission of hypertension (not
requiring anti hypertensive drugs) coupled with significant
weight loss ranging from 15 to 25%. There was significant
improvement in secondary outcomes measured.
Conclusion.
Our
preliminary data demonstrated the feasibility, safety and
efficacy of this novel surgical procedure in type 2
diabetes. Further long term data from more number of
patients is necessary to confirm these findings.

Clinical profile of Iatrogenic Neuroglycopenia.
Pasupuleti Ravi Kishore, Vidyasagar Sudha, Seth
Pankaj, Varma Muralidhar, Prashanth. Kasturba Medical
College, Manipal.
Objective.
To study
clinical profile of neuroglycoponia in patients with type 2
diabetes mellitus.
Methods.
The clinical
profile of patients admitted in Kasturba Hospital, Manipal
with neuroglycopenia between 2005 Jan to 2008 August were
observed with respect to demographic details, duration of
diabetes, precipitating factors, clinical manifestations,
drug therapy, and complications.
Results.
Of the 20
diabetic patients, the mean age was 61.68yrs, 45% being
above 60yrs. 14 (70%) of patients had altered sensorium,
5(25%) had coma, 3 patients had <30mg/dl,12 had 31-50, 5 had
>50mg/dl of capillary glucose.
Reducing the food due to illnesses was the most important
precipitating factor 80% (16). 13 were patients on insulin
and OHAs, 7 were on sulfonylureas or combinations. 7 had
diabetes >10 years, 3 had diabetes for 5-10 years. 10 were
diabetic for <5years and in these 4 were on insulin, 2
self-adjusted the dose of drugs and 2 were newly started on
drugs. Chronic renal failure was an important
association(25%). Past history of hypoglycemic attack was
present in 2 patients. 5 patients were alcoholics.
Conclusion.
Neuroglycopenia is common in elderly. The most important
precipitating factor being reduced food intake during
illness. Most common clinical presentation is altered
sensorium. Chronic renal failure has significant
association, probably as these patients are on insulin. CNS
manifestations are common in the initial phases of drug
therapy as patients are unfamiliar with warning symptoms or
in patients with >10yrs of diabetes.
We feel all patients should be educated about use of drugs
in diabetes, especially in elderly age group and those on
insulin.
Iatrogenic hypoglycaemia –A physician’s challenge.
Srivastava S, Ahmad S, Verma SK, Shirazi N.
Himalayan Institute of Medical Sciences, HIHT University,
Swami Rama Nagar, Jolly Grant, Dehradun.
Introduction.
Iatrogenic
hypoglycaemia is the limiting factor in intensive glycemic
control in subjects with diabetes mellitus.
Over-enthusiastic prescription of anti-hyperglycaemics has
increased the incidence of hypoglycaemic episodes over and
above the incidental and accidental occurrences.
Material and Methods.
All the
diabetic and non-diabetic patients with low blood glucose
levels (<40 mg/dL) at presentation to the Himalayan
Institute of Medical Sciences, Dehradun, were included in
the study; those with septicaemia, liver dysfunction, and
malignancy-associated anorexia, were excluded.
Results.
We
encountered 62 patients with iatrogenic hypoglycaemia over a
period of 8 months. The male to female ratio was 1:3 and the
median duration of diabetes was >5 yrs. Thirty-eight
patients [61.2%] were aware of the symptoms of hypoglycaemia;
others presented with unconsciousness [n=12, 19.3%],
seizures [n=2, 3.3%], unconsciousness with hemiparesis [n=2,
3.3%] and uncontrolled blood glucose levels [n=8, 12.9%].
Sulfonylurea- and insulin-associated hypoglycaemia was seen
in 37 [59.6%] and 24 [38.7%] instances respectively. One
non-diabetic was a rare case of fluoroquinolone (moxifloxacin)
induced hypoglycaemia. The most prominent causes of
iatrogenic hypoglycaemic episodes observed in our study were
over-enthusiastic use of anti-hyperglycaemics; frequent
escalation of doses; ignorance of associated co-morbidities
predisposing to dysglycaemia; use of alcohol; renal
insufficiency, vigorous exercises and missing a meal.
Conclusion.
Increasing
pressure advertising by the pharmaceuticals and lack of
patient-doctor coordination are perhaps the core issues
behind the increasing incidence of iatrogenic hypoglycaemia
which may occasionally be crippling and fatal.
Iatrogenic Hypoglycemia: Sweating to glycemic control may
cause Cognitive Impairment.
Anuj Maheshwari, U.P.D.C. and Research Centre,
Lucknow. Nisha Maheshwari, Sri Hari Kamal. Diabetes and
Diabetic foot Clinic, Lucknow.
In last decade, with recommendations of targeting tight
glycemic control, hypoglycemia has come up as a significant
denominator in achieving perfection in wellbeing. Desiring
precise post prandial glycemic control to avoid CV risks,
convenience of premixed Insulin is being fatal not only
posing risk of hypoglycemia especially when peaks of NPH and
regular insulin coincide but also increasing weight most
likely because of unscheduled snacking during Hypoglycemia
then to Insulin pharmacodynamics. Analogues were introduced
to avoid hypoglycemia using their shorter duration of
action. Despite it, twice a day popularly used premixed
analogues, cause significant diurnal glycemic variability.
In spite of good HbA1c, controlled glucose level at fasting
or post-prandial, a high pre dinner value forces clinician
to increase dose of insulin. It may lead to hypoglycemia
causing more frequent snacking and weight gain. Regular
occurrence of this blunts endocrine defenses and
counter-regulatory response to hypoglycemia. The failure of
the symptomatic counter-regulatory response, leads to
decreased perfusion and brain Glucose uptake in sub thalamic
brain centers, including ventromedial and lateral
hypothalamus, making him unaware of hypoglycemia. Many
patients complain of short term memory loss, being
intolerant and short tempered, lack of concentration, having
disinterest in surroundings gradually amounting to
depression, losing interest in work etc.
An observational clinical study of hypoglycemia was done
among 212 diabetics taking insulin or analogue or their
premixed combinations with or without oral drugs in 12 weeks
which was later on extended to 24 weeks. They were advised
to check blood glucose at least twice daily even if they did
not have any problem and to check in addition when they feel
themselves hypoglycemic or having unexplained symptom. Data
on glucometers were downloaded and analysed. 188 patients
completed study comprising of 53% males and 47% females. 24
patients did not use glucometers or lost to follow up. 32%
shown classical symptoms of hypoglycemia confirmed with
glucometers while 8% could not confirm their symptoms with
Glucometers but relieved on correction. 63% of hypoglycemia
noticed with premixed insulin with highest weight gain
followed by premixed analogue but without significant
difference in weight gain. Least hypoglycemia noticed in
Basal Insulin supported by oral drugs without weight gain
followed by Basal Bolus Therapy with least weight gain.
Highest diurnal glycemic variability was observed with
premixed analogues twice daily regime while it was least
with basal bolus. Hypoglycemia unawareness found to be
highest with premixed analogue which was intending to
increase with duration followed by premixed insulin and
least with Basal oral therapy. Cognitive impairment was
noticed to be exponentially increasing with tight and
consistent glycemic control, of course more with premixed
analogue. Weight gain was more with post prandial tight
control or hypoglycemia.
Although consistent tight glycemic control helps in avoiding
microvascular complications, but exploring perfection
through intensive lowering of blood glucose and setting new
standards of lowering HbA1c, may compel our patient to sweat
for irresistible desire to eat. On one hand it may increase
weight and insulin resistance posing cardiovascular risks
and on another hand regular occurrence develops unawareness
to hypoglycemia passing through the cognitive impairment.
Targeting new lows of blood glucose may induce hepatic
glucose output causing undesirable glycemic variability that
makes it difficult to keep round the clock optimum control
and ultimately patient sweats off clinicians efforts.
Serious symptomatic hypoglycemia in a patient on insulin
pump.
Jothydev Kesavadev, Arun Shankar, Dhanya K Gopi,
Sunitha Jothydev. Jothydev’s Diabetes and Research Center,
Trivandrum.
In T1DM, high A1c and recurrent low sugars poses a treatment
challenge. Use of Insulin pumps reduces hypos enabling
patients maintain near normal sugars. This report of serious
symptomatic hypoglycemia, requiring hospitalization,
cautions us in taking into account multiple factors in
determining basal profiles and bolus insulin dosages in
patients with wide glycemic excursions, while on pump.
Here we document the case report of 26 y.o T1DM, 16 years
duration, on MDI from our center. He used to experience
frequent hypoglycemias which easily got corrected by oral
ingestion of glucose. His A1c remained >10% and was switched
over to CSII. Initial insulin in pump was <20% previous
dose. He was on daily follow up by our diabetes
team.(Diabetes Tele-Management System-DTMS). One month
later, ½ an hour after lunch, waiting for bus, he recalls
symptoms of hypoglycemia, suspended pump but immediately
fell down unconscious. He completely recovered in hospital.
Later he underwent a series of educational sessions with
diabetes team on carb counting, insulin sensitivity factor,
using bolus wizard, temporary basal at times of exercise and
walking etc. He has now completed >2 years on pump with no
further hypo but acceptable A1c.
Close follow up is mandatory during the initial 3-6 weeks so
as to optimize insulin delivery. Smart pumps when combined
with intellectual and mathematical skills of patients and
care givers offers the best benefit of an advanced insulin
delivery mechanism mimicking a normal pancreas only in
motivated subjects.

Plasma Adiponectin and central obesity in type 2
diabetes. Nitin Kapoor, Neeta Deshpande,
Kalagate SB, Kothiwale VA. JN Medical College, Belgaum.
Aim.
To
correlate plasma adiponectin with obesity in type-2
diabetes.
Methods.
90 age
matched male subjects were divided into 4 groups based
on BMI: Diabetic overweight –DO(n=35), Diabetic normal
weight -DNW(n=35), Non Diabetic overweight-NDO(n=10) and
Non Diabetic Normal weight -NDNW(n=10). Only well
controlled (HbA1c <7.5%) diabetics with normal ECG and
not on thiazolidinediones were included. All were
studied with respect to anthropometry (BMI&WHR) and
Plasma adiponectin(Measured by ELISA,both globular and
full-length).
Results.
Mean
adiponectin is higher in non-diabetics compared to
diabetics. Among the 4 groups adiponectin levels were
lower in the two overweight groups (DO, NDO) Vs
non-overweight groups (DNW, NDNW). (P<0.001). There was a statistically significant (P<0.001)
inverse relation between the range of BMI values and
Plasma Adiponectin amongst diabetics. Based on WHR,adiponectin levels were significantly
lower(P<0.001) in the centrally obese subjects compared
to normal-WHR subjects, whether diabetic or not. The correlation coefficient of reduced adiponectin is
higher with WHR (+0.9209 and +0.9690 for diabetics and
non-diabetics respectively) than with BMI (+0.7494 and
+0.6924 for diabetics and non-diabetics respectively).
Although all diabetic subjects had good glycemic control
(HbA1c <7.5), there was a statistically significant
inverse relation between the range of HbA1c values and
Plasma Adiponectin, whether in overweight (p=0.0067) or
normal weight (p=0.0046)Conclusion.
Both diabetes and obesity have an inverse correlation
with Adiponectin.
Plasma adiponectin levels correlates better with WHR
than BMI and probably predicts insulin resistance and
development of atherosclerosis.
Even within a normal range of HbA1c, lower values were
associated with higher adiponectin.
Prevalence of metabolic syndrome among South Indian subjects
with elevated intermediate glucose response during OGTT.
Vijay V, Satyavani K, Clementina M, Priyanka T.
Diabetes Research Centre and MV Hospital for Diabetes,
Royapuram, Chennai.
Aims.
Individuals with IGT or IFG are at high risk
of developing type 2 diabetes and CVD. In earlier report, we
found that a larger percentage of subjects having an
elevated intermediate post glucose response (1 hour value
of=160 mg/dl, Early Glucose Intolerance, EGI) during OGTT
converted to diabetes compared to normoglycaemic subjects.
The aim of this study was to see the prevalence of metabolic
syndrome among EGI subjects.
Methods.
A total of 1107 subjects (M:F; 745:362)
enrolled for a ‘primary prevention program’ were selected. A
standard OGTT was done and the subjects were divided into
groups based on their glucose tolerance status, NGT(n=402),
EGI(n=405), IGT(n=300). Anthropometric and blood pressure
measurements were recorded. Biochemical investigations were
done using enzymatic procedures. Diagnosis of metabolic
syndrome was made using ATP III criteria with modified waist
circumference appropriate for Indians.
Results.
The prevalence of metabolic syndrome was
significantly higher in EGI (36.1%) compared to NGT (27.9%)
(c2=5.8,
p=0.015). Presence of metabolic syndrome was higher in IGT
(57%)when compared with NGT and EGI (p<0.0001). Presence of
individual abnormalities such as increased FPG, BMI and BP
were higher in EGI than NGT. Multiple logistic regression
analysis with presence of metabolic syndrome as dependent
variable showed a significant association with
EGI (OR 1.76;
95%CI 1.23 – 2.5) and IGT (OR 3.97; 95%CI 2.7 – 5.8) (p =
0.001)Conclusions.
EGI which is
a distinct entity showed a significantly higher prevalence
of metabolic syndrome than normoglycaemic subjects.
Diagnosis of metabolic syndrome among these individuals
might help in prevention of diabetes and cardiovascular
disease.

selected for this study. A total of 719 men aged = 30 years
from Chennai, were randomly selected (police n = 318, GP, n
= 401). Fasting blood samples were collected, glucose and
lipid profile were estimated. Prevalence of metabolic
syndrome was determined using IDF definition. Risk
associations for metabolic syndrome and diabetes were
analyzed using multiple logistic regression analyses.
Results.
The prevalence of metabolic syndrome (57.3 vs
28.2 %; ÷2 = 64.5, p< 0.0001) was significantly higher among
police compared to GP. Regression analyses showed that age,
body mass index, alcohol consumption and smoking were
associated with metabolic syndrome while age, family history
of diabetes, abdominal adiposity and increased body mass
index were associated with diabetes among the policemen. The
police had higher prevalence of individual cardio metabolic
abnormalities and diabetes in comparison with GP (p<0.05).
Conclusions.
Prevalence
of metabolic syndrome and other cardiometabolic
abnormalities were significantly higher among the police.
Further research is required to determine the causative
factors and effective intervention strategies must be
planned to keep the police force healthy and vigilant.
Insulin resistance and other metabolic abnormalities in
‘Normal Weight Obese’ type 2 diabetics.
Deshpande N R1,2,
Aman SD2, Pilankar R2, Dhareshwar R2.
1KLE’s Dr Prabhakar Kore Hospital and MRC,
Belgaum, 2Belgaum Diabetes Centre, Belgaum.
Background.
It is
postulated that body fat is more strongly associated with
development of insulin resistance and other risk factors of
atherosclerosis. Since Normal Weight Obesity (NWO) is a
clinical entity with predominant visceral obesity, this
study aimed at finding the degree of insulin resistance and
other metabolic abnormalities among the NWO type 2
diabetics.
Aim.
To study insulin resistance and other
metabolic parameters in ‘Normal Weight Obese’ type 2
diabetics.
Methods.
97 type 2 diabetics attending a diabetic
clinic were evaluated for clinical and laboratory metabolic
parameters. Only male, freshly detected type 2 diabetics
were included so as to form a uniform cohort of subjects.
Insulin resistance (IR) was calculated by HOMA-IR index. NWO
was defined as body fat>20% with normal body weight(BMI<25
kg/m2).
The data was compared with overweight (BMI>25 kg/m2)
and non obese individuals (BMI<25 kg/m2 and
body fat<20%). Data was statistically analyzed.
Results.
Of the 97 subjects studied, 46 subjects had
normal BMI, of whom, 64% had NWO. Statistically, most
metabolic parameters in the NWO group were similar to the
frankly obese group, especially fasting insulin levels, IR,
total cholesterol, LDL-C, triglycerides, uric acid, HDL-C.
On the other hand, the same parameters were grossly deranged
in the NWO group as compared to the non-obese group -p
values: 0.009 (cholesterol), 0.03 (triglycerides), 0.03
(LDL-C), 0.05 (HDL-C), 0.03 (fasting insulin), 0.04 (uric
acid). The mean IR in the NWO group (IR=64.9) was twice that
in the non-obese group (IR=31), but almost equal to that in
the obese group (IR=74). There was no significant difference
in glycemic control, blood pressure, SGOT, SGPT, between
various groups.
Conclusion.
Most
metabolic parameters in the NWO group veer more towards the
frankly obese group and are far more deranged than in the
non-obese group. Thus, measuring BMI alone would miss this
distinct category of subjects that comprises a large
proportion of apparently non-obese (by BMI) individuals.
Larger studies would be needed to emphasize importance of
routinely measuring fat percentage as a better indicator of
metabolic abnormalities.
Is there need for assessing cardiometabolic risk factors in
young healthy asymptomatic individuals?
Manohar KN, Agarwal A, Agarwal G, Bhattacharyya A.
Lotus Health Care Center, Indiranagar, Bangalore.
Aims &
Objectives.
The
prevalence of T2DM,
HBP, and CAD is on the rise more so in people in Indian
subcontinent. Our aim is to justify the need for routine
health screening for cardiometabolic risks in young
asymptomatic healthy individuals.
Methods.
Young asymptomatic healthy individuals were
subjected to history, examination and biochemistry including
blood sugar and Lipid profile.
Results.
Four hundred and fifty four subjects
constituted this cohort, 61.5% males; average age was 26 (21
– 30y), 34% had a family history of cardio-metabolic risk
(including HTN, T2 DM,
IHD, CVA), 28% of the males were smokers. As per ICMR, 22%
were overweight while 40% were obese. Prevalence of
hypertension was 9% (reconfirmed on subsequent visits) while
9 % had diabetes and 11% had IGT. Most alarming abnormality
was in lipid profile at 46% (36% high total cholesterol, 43%
high Triglyceride, 9% low HDL and 12% high LDL cholesterol
and 32% combined dyslipidaemia). Of the 21% people with
abnormal carbohydrate tolerance, 16% had a positive family
history of diabetes, 14% had associated hypertension and 35%
had dyslipidaemia. Amongst people with hypertension 16% had
diabetes & 60% had abnormal lipid parameters. Of the cohort,
only 44% had all lab parameters (blood sugars and
cholesterol) in normal range. Resting ECG was normal in all
cases.
Conclusion.
We recommend
blood sugar and lipid analysis apart from physical
examination at predefined intervals in young healthy
asymptomatic individuals. We can take the advantage for
pre-employment health check in young adults to unfold such
abnormalities.

Childhood Obesity Prevalence Study.
Sunil Gupta, Archana Bhojwani, Manisha Phadke.
Diabetes Care ‘n Research Centre, Nagpur.
Aim.
To study prevalence of childhood obesity
amongst school going children and its corelation with
dietary habits.
Method.
1010 children of age 10-12 years were
selected from two schools of varying socio-economic
background. A complete record of the food intake by using 24
hrs 3 days dietary recall method with dietary fat intake and
physical activity profile was collected from parents. Birth
Weight (BW) of the child was correlated with present body
weight (wt). Food habits like veg, non-veg, fast food,
eating in food joints, meals with watching T.V was also
noted. Body fat monitoring alongwith anthropometric
measurements such as height, weight, waist, hip were
recorded using standard methods. A detailed questionnaire
was applied to all subjects.
Result.
As per CDC growth chart Childhood Obesity
(CO) was seen in 7.1%, M-61 (10.3%),F-10 (2.4%). Risk of
Overweight (ROO) was in 136 (13.5%), M-117 (19.8%), F-19
(4.5%). Underweight prevalence was 128 (12.7%) M-54 (9.2%)
F-74 (17.6%). Mean Calorie and total fat intake amongst CO
and ROO subjects was more compared to others [1669 Cal vs.
others-1506 Cal\d and fat Intake 37.5 g\d vs. others 32.4
g\d respectively]. SFA intake was more in CO and ROO
children than others (10.1 g\d vs. 6.2 g\d).
Conclusion.
Obesity was
found higher among males than females. Childhood obesity was
more prevalent among higher income group. Low birth weight
and macrocosmic children are more prone to become obese.
Association of non alcoholic fatty liver disease with
diabetic micro- and macro-vascular complications in South
Indian diabetic subjects.
Vijay V, Srikanth M, Mahesh K, Satyavani K. Diabetes
Research Centre and MV Hospital for Diabetes, Royapuram,
Chennai.
Aims.
Nonalcoholic
fatty liver disease (NAFLD) is a common liver
disorder that is strongly associated
with insulin resistance and type 2 diabetes.
The main purpose of this study was
to see
whether there is an association between NAFLD
and diabetic micro and macro vascular complications among
diabetic subjects.
Methods.
The subjects were selected from 2,161 (M: F,
1187: 974) type 2 diabetic subjects who regularly attended a
tertiary diabetes care center and undergone
ultrasound of abdomen for assessment of fatty liver. A total
of 156 patients with evidence of NAFLD (group1) were
compared with 142 (group-2) randomly selected from patients
with normal liver ultrasound. Presence of micro and macro
vascular complications of diabetes were recorded. Ultra
sonography was done for all the subjects.
Results.
HbA1c and liver enzymes levels were
significantly higher in subjects with NAFLD compared to
subjects without NAFLD. Prevalence of obesity, hypertension
and dyslipidaemia were significantly higher in subjects with
NAFLD. They had higher prevalence of retinopathy (29.4% vs
9.8%, p<0.001), neuropathy (27.5% vs 10.5%,p<0.001),
nephropathy (32vs 25%,p=0.2). The prevalence of CAD among
NAFLD patients (11.5%vs1.4%, p=0.01) was higher and POVD was
similar in both the groups. The results of multiple logistic
regression analysis showed that NAFLD was associated with
BMI, retinopathy, neuropathy and CAD.
Conclusions.
Our study
concluded that NAFLD as diagnosed by ultra sound was
associated with micro and macro vascular complications of
diabetes. Prevalence of obesity, hypertension and
dyslipidaemia were significantly higher in subjects with
NAFLD.
Foot abnormalities in diabetics – Prevalence and predictors.

Diabetes Centre, Belgaum.
Background.
Diabetic
Foot/amputation is a highly disabling complication and also
the most frequent cause of hospitalization, reducing quality
of life. It is preventable by proper education. India is the
‘diabetes capital’ of the world. Yet there is lack of
awareness about the risk factors. This study was planned
with the intention of evaluating risk factors that can be
associated with development of diabetic foot while
considering various ethnic and cultural practices such as
bare foot walking (socioeconomic, occupational and religious
reasons).
Aim.
To estimate prevalence of foot abnormalities
among type 2 diabetics and predictors of these abnormalities
in a diabetic population.
Methods.
160 randomly selected Type 2 diabetic
subjects attending a diabetic clinic were subjected to foot
assessment. Evaluation for various risk factors of diabetic
foot (neuropathy & vasculopathy) was performed by trained
podiatrists. The subjects were categorized as cases (with
foot abnormalities) and controls (without foot
abnormalities). Data was analyzed to compare risk factors in
both groups.
Results.
· Total
screened = 160
·
Subjects with foot abnormalities = 73 (45.62%)
Variables
studied included poor socio-economic status (SES), high-risk
occupations (farmers, mechanics), urban/rural setting,
smoking, hypertension, diabetes duration, glycemic control.
Variables that predicted foot abnormalities were poor SES
(p=0.02), high-risk occupations (p=0.03), smoking (p=0.01)
and hypertension (p=0.02). Glycemic control and diabetes
duration were similar in both groups. However, subjects in
study group were on multitherapy for diabetes (p=0.03) and
had higher rate of retinopathy (p=0.08).
Conclusion.
Factors
other than glycemic control and diabetes duration are
probably operative in causation of diabetic foot in specific
ethnic/cultural groups.
Study of Rheumatological manifestations in type 2 diabetes
mellitus.
Agrawal NK, Amit Bhaskar, Amit Rastogi, Naik D,
Valvani A. Department of Endocrinology and Metabolism,
Institute of Medical Sciences, BHU, Varanasi.
Objective.
To study the
prevalence of rheumatological manifestations in patients
with type 2 diabetes mellitus.
Material
and Methods.
This is a
hospital based cross-sectional study involving 101 patients
with type 2 diabetes with rheumatological manifestations.
They were clinically evaluated and were assessed for
glycemic status, glycosylated haemoglobin (A1c), serum total
protein, albumin, calcium, phosphorus level were measured.
They were also subjected to x-rays to rule out bone
abnormalities.
Result.
There were 51 males. The mean age was 53.8
years. The rheumatological manifestations were common in
males of 46-55 years of age. Mean duration of diabetes was
8.4 years. Maximum numbers of cases (40%) were wthin 1-5
years of detection of diabetes. Adhesive capsulitis was seen
in 53 patients while 30 patients had osteoarthritis, 12
patients had diabetic hand syndrome, 6 patients had shoulder
hand syndrome, 3 patients had osteoporosis, 1 patient each
had hammer toe and trigger finger. Out of 53 patients of
frozen shoulder male were 30 (56.6%) and females were 23
(43.4%). In osteoarthritis majority of were female ie. 20
(66.67%). Eight out of 12 patients having diabetic hand
syndrome were male (66.67%). Out of 6 cases of shoulder hand
syndrome 4 were male. All 3 cases of osteoporosis were
female. 1 case of hammer toe and trigger finger was seen in
male and female respectively. Mean fasting plasma glucose,
postprandial plasma glucose were 138.6 mg% and 194.6 mg%
while the mean A1C level was 9.27%. The mean serum calcium
and phosphorus level were 9.46 mg% and 3.9 mg% respectively.
HbA1c
> 9% was found in 49% patients with frozen
shoulder, 47% of osteoarthritis cases, 75% cases of diabetic
hand syndrome, 83% patients of shoulder hand syndrome and
all patients with osteoporosis.
Conclusion.
Rheumatological manifestations occur early in the course of
diabetes in middle aged patients; adhesive capsulitis being
commonest followed by osteoarthritis and diabetic hand
syndrome. Poor glycemic control is associated with increased
prevalence of rheumatological diseases.
Does UTI Pathogen differ in diabetics ?.
Sarita Ugemuge, Sunil Gupta. Sunil’s Diabetes Care
n’ Research Centre, Nagpur.
Aim.
To study the etiological agents &
resistance to various antimicrobial agents in diabetic
population suffering from UTI.
Material
and Methods.
A total of
106 urine samples of diabetic subjects tested for aerobic
bacterial culture. Isolates were identified by standard
methods and antimicrobial susceptibility testing was carried
out by Kirby Bauer’s method.
Results.
Out of 106 samples , 54 (50.94%) samples were
found to be positive for pathogens. 96.3% cultures were
gm-ve bacilli, with Klebsiella being the commonest
isolate (74.07%) followed by E. coli (22.22%). The
antibiotic susceptibility of the isolated cultures was
performed following NCCLS guidelines. For antibiotics, such
as Norflox, Ciprofloxacin, Cefadrox, Cefuroxime and
Cefixime, more than 50% of the Klebsiella cultures
were resistant, while for other antibiotics the
susceptibility pattern showed variation from 10 to 40%
(susceptible samples). In case of the E. coli
cultures, the maximum percentage of samples resistant to any
antibiotic was 33%. The comparative assessment showed that
the % of antibiotic resistant Klebsiella isolates
were significantly (P<0.05) more than the E. coli
isolates.
Conclusion.
Amongst
UTI of diabetics Gram negative bacilli were commonly
isolated. Klebsiella was the most frequently
encountered UTI pathogen (unlike in nondiabetic UTI, where
E. coli is more commonly seen) The antibiotic resistance
pattern of pathogens indicated significantly (P<0.05) high
number of resistant Klebsiella than E. coli.
Klebsiella was found to be resistant to more number
of antibiotics than E. coli.

Kumaramangalam Medical College, Salem.
Background.
C-reactive
protein (CRP) is an acute-phase
protein [2] produced by the liver and adipose
tissue during episodes of inflammation. Recent findings
have suggested that even slightly elevated
concentrations of (CRP), have predicted coronary
events in Diabetes and hypertension patients
in several studies [4-8].
Aim.
To assess the hs-crp levels in diabetes and
hypertension patients
Methods
and Materials.
70 patients with diabetes and 70 patients with hypertension
were selected from diabetes clinic and hypertension clinic
separately at GMKMC Hospital, Salem. Age, sex, history and
general examination findings were recorded. The blood
samples were centrifuged and the serum collected was stored
in deep freezer at -20c in microbiology lab. These samples
were then sent for testing hs-crp levels at National
Institute Of Biologicals,Noida.
Statistical analysis used.
chi square
test, p value, annova test
Results.
hs-crp levels were high in diabetic patients
in comparison to hypertension patients (P 0.471). Diabetic
males were having high hs-crp levels in comparison to
diabetic females(P 0.005). Hypertensive males were having
high hs-crp levels in comparison to hypertensive females (P
0.595). Patients with diabetes for >3 years were having high
hs-crp levels in comparison to those <3 years(P
0.000).Patients with hypertension for >3 years were having
high hs-crp levels in comparison to those <3 years.
(P:0.000)
Conclusions.
CRP is
strongly correlated with both diabetes and hypertension.
However, Diabetic patients have high HS-CRP levels than
Hypertension patients. Hence, HS-CRP levels must be
monitored in Diabetic patients.
A novel invitro method for screening of Anti-AGE molecules. Sachin S Pawar, Prachi S Lukatuke, Chaitrali C Kulkarni, Aneri p
Manvar, Ghanshyam B Srivastava.
Abstract.
Glycation is a reaction in which sugars react
non- enzymatically with a wide range of proteins to form
Advanced Glycation End Products (AGEs). The procedure to
form and assay AGEs are far complex, therefore we have
devised a simple high throughput screening method (HTS) for
evaluating of anti-AGE molecules. Glucose (50mM) and Bovine
Serum Albumin (50mg/ml) was autoclaved using set parameters
for formation of AGEs. Flourimeter analysis at
(Ex360nm/Em440nm) was the method used to determine extent of
glycation. Metformin ( 1mM) and Diclofenac (1mM) were used
as standards. There was marked increase in flourimeteric
readings of the mixture of glucose and albumin, which was
inhibited by Diclofenac and Metformin. Thus autoclaving
followed by flourimeteric analysis may be HTS procedure for
the evaluation of (new chemical entities) NCEs for the
therapeutic intervention of AGEs.

In 1956,
observations on a diabetic patient requiring 20 units of
insulin showed that he ceased to have glycosuria for three
months during which his food included 4-6 oz a day of tender
field beans (Dolichos lablab), a popular seasonal vegetable
of Karnataka. Unlike the tender seeds, the mature seeds had
no effects. This observation was strongly indicative that
the proteins in foods exerted a favorable effect on
carbohydrate utilization.
Glucose
tolerance tests carried out on a total of 54 T2DM patients
given 30 g of casein along with 75g of glucose showed that
blood sugar levels at the corresponding intervals in the
tests with the protein & glucose together, were lower than
in the controls, in two-thirds of the cases, confirming the
favorable effect of protein on carbohydrate utilization.
Further
experiments conducted on 20 adult cases of T2DM patients
showed that proteins evoke a marked endogenous response to
insulin secretion. This was adequate to explain the effect
of protein on blood sugar levels. Supplements of daily diets
of 20 T2DM patients with 30 g casein protein for a period of
6 to 8 weeks brought down the insulin requirements, as shown
by a fall in fasting glucose levels in two-thirds of the
subjects. Withdrawal of protein from the diet resulted in a
prompt rise in fasting sugar levels calling for increased
insulin dosage. In a second trial with 30 subjects glucose
tolerance done in many cases when the patients were on
protein supplementation, showed improved performance in
tolerance tests
It was
concluded from the experiments that a 30g supplement of
protein per day is equivalent to about 20 units of insulin
showing that food is an essential factor to control
hyperglycemia through enhanced insulin activity by protein.
In recent years, several studies conducted on T2DM subjects
have reported that glucose concentration did not increase
after protein ingestion but insulin levels increased
markedly and this results in rapid storage of glucose in
liver and skeletal muscles.
Oats – A Functional Food and an alternative medicine for
diabetics in developing countries. Lakshminarayan V1,
Venkat Rao S1, Murali TSR2. 1Shreehari
Diabetes Foundation, Kuvempunagar, Mysore. 2
Pepsico Holdings Pvt Ltd, Gurgaon.
Introduction.
Oat grain is
a wonderful reservoir of natural nutrients and biologically
active substances. Russia, USA, Canada, Northern Europe are
the main producers of oats and the world production is 50
million tons per year. Traditionally, the largest use of
oats has been for animal feed. The beneficial nutritional
and physiological effects of oat products has generated an
increased demand for oats in human nutrition, eg. reduction
of serum cholesterol and glucose levels by beta-glucans and
other dietary fibre components.
Conclusions from our Study
1. GI value of quick cooking oatmeal is in
the moderate range (i.e., <70) at the end of 2hr. (high GI >70, moderate GI 56-69 and low GI <55).
2. The
optimum quantity of oats for breakfast is around 50g, in
order that postprandial sugar levels are moderately
increased.
3. Around
50g of quick cooking oatmeal is advised for breakfast for
diabetic patients.
Effect of sucralose on glycation.
Kulkarni CC1,
Luktuke PS, Manvar AP, Shrivastav GB.
Sinhagad Institute Of Pharmacy, Pune
Objective.
Diabetes is the disease of complications. The complications
of the diabetes are more agonizing and torturing than the
disease itself. Glycation is called as the non- enzymatic
glycosylation as a result of sugar bonding to the protein
molecule. Itr is the haphazard process that impairs the
functioning of biomolecules. It involves the evolution of
the molecule through a complex series of the reactions
Amadori product, Schiff base, Millard reactions and lastly
the molecule form AGEs (Advanced Glycation End Product).
AGE’s are implicated in the initiation of renal dysfunction,
cardiovascular diseases, type-2 diabetes and other age
related chronic diseases. Artificial sweetener helps the
consumer to cut down on calories and control weight, help to
manage the chronic condition such as diabetes.
Sucralose is the low-calorie sweetener made from table sugar
(Sucrose). Sucralose in reality it is about 600 times
sweeter than sugar and can be used in place of sugar to
eliminate or reduce calories in a wide variety of products,
including beverages, baked goods, desserts, dairy products,
canned fruits, syrups and condiments. The toxicity studies
done on sucralose have clearly indicated as non-toxic
compared to other sweeteners but till date no study onits
effect on glycation has been done.
Method.
The studies are carried on the effect of
glycation of sucralose on model protein such as insulin,
in-vitro by measurement of Fluorescence at Ex 370nm/Em
400nm.
Result.
The readings
are taken under two conditions such as hot air oven (600
) and the incubator (370).
The Sucralose shows increa sed fluorescence (66-hot air
oven,87.33-incubator on average) as compared to, sucrose
(4.5-hot air oven,10.16-incubator on average).
Conclusion.
This clearly
indicates sucralose shows more glycation than thsucrose,
which needs to be addressed, and its mechanism needs to be
further investigated.
Effect of Trigonella foenum on fasting blood glucose levels
in Alloxan induced diabetes in rabbits. Subhani G, Mujtaba
S. Kamineni Institute of Medical Sciences, Narketpally.
Introduction.
Anti-diabetic plant medicines might provide an important
source of new oral hypoglycemic compounds for development as
pharmaceutical entities, or as simple dietary adjuncts to
existing therapies.
Aims and Objectives.
To study the
hypoglycemic effect of seeds of Trigonella foenum (methi).
Material and Methods.
Alcoholic
extract of fenugreek seeds was prepared by cold percolation
method over 24hrs using a Soxhlet apparatus. Diabetes
was induced in rabbits by administration of Alloxan at
150mg/kg body wt IV. Rabbits with fasting blood sugar
220-500mg/dl were considered diabetic. Diabetic rabbits were
divided into groups (n=6) receiving different
treatments: vehicle (control), standard antidiabetic drug
Metformin (62.5mg/kg b.w) Alcoholic extract (0.5g, 1g and
1.5 g/kg b.w), for 35 days. Blood samples were analyzed for
fasting blood glucose daily for the fifteen days and the
once weekly for 3weeks.
Results.
The mean
blood glucose levels in the treatment group with low, medium
& high doses of extract were (179.16, 151.66, 127.5mg/dl at
the end of 5 weeks. The mean blood glucose levels in the
control and positive control group at the end of 5 weeks
were (266.83 & 112.66). Observed data was found
statistically significant (P<0.05) in reduction of
fasting blood glucose.
Conclusion.
Fenugreek
extract has shown significant reduction in fasting blood
glucose levels in diabetic rabbits. They may reduce the
dosage of antidiabetic agents when given as a dietary
adjunct. The broad dose range of the extract producing
hypoglycemic effect in diabetic rabbit was an interesting
observation, which requires further study.

Bikaner.
Objectives.
The present investigation was carried out to find out the
hypoglycemic effect of Aloevera juice on type 2 diabetic
patients.
Material and Methods.
24 type 2
diabetic patients were recruited from the out patients of
Diabetes Care & Research Center, Bikaner with maximum
possible homogeneity in age, sex, occupation and life style.
The subjects were divided into two groups: Group 1 (control,
n=12) were given conventional treatment i.e. diet, exercise,
drugs while group 2 (experimental, n=12) were given 150ml
freshly extracted alloevera juice daily during fasting stage
in addition to the conventional treatment for 3 months. The
biochemical and biophysical parameters were analyzed
initially and after 3 months.
Results.
Significant
changes were noticed in group-2 for fasting blood sugar
(196.75±39.59 to 124.17±33.12mg%) and HbA1c
(8.66±1.004 to 6.2±0.98mg%). There was also significant
improvement in the lipid profile of group-2 after aloevera
juice supplementation i.e. total cholesterol (203.5±28.62 to
174.45±25.09mg%), triglycerides (186.21±18.75 to
113.92±19.99mg%), HDL (38.36±3.38 to 51.08±3.65mg%), LDL
(124.93±25.84 to 100.76±21.21mg%) and VLDL (37.24±3.75 to
22.78±3.99mg%). There was a slight reduction in BMI
(26.38±1.06 to 25.04±0.93) and WHR (0.96±0.03 to 0.94±0.03).
Conclusion.
It can be
very well concluded that aloevera juice consumption provides
better glycemic control alongwith improvement in lipid
profile as well as anthropometric measurements.

Hypercholesterolemia is a main corn stone of attention in
patients suffering from diabetes. Rheum ribes (Rr) and
Cynara scolymus (Cs) are used in traditional medicine for
treatment of hypercholesterolemia.
Aim.
To
investigate the efficacy of Rr stalks and Cs leaves extract
in treatment hypercholesterolemia in type II diabetic
hypercholesterolemic patients.
Methods.
A one-month
randomized double blind clinical trial was conducted in 54
type II diabetic hypercholesterolemic patients in a 3
well-matched groups (n=18). Three groups received Rr, Cs and
placebo tablets at the dosage of 400 mg, respectively 3 time
a day plus standard therapy. The patients fasting blood
sugar (FBS), cholesterol (Cho), LDL, HDL, triglyceride, SGOT
and SGPT were determined at the beginning and at the end of
the study after one month.
Results.
In Rr
treated group Cho, LDL, FBS level and in Cs treated group
Cho level after one month were significantly decreased as
compared to placebo group.
Conclusion.
The Rr
therapy have beneficial effect on reducing lipid and glucose
profile as well as Cs has beneficial effect on
reducing cholesterol level in hypercholesterolemia type II
diabetic patients.

Type II diabetes Mellitus is an increasing health problem
with the prevalence of the disease doubling year by year.
The occurrence of Diabetes in adults worldwide is estimated
to be above 4.0% and found to rise up to 5.4% in 2025, even
with the existence of the Anti Hyperglycemic therapies. This
is higher in the developed countries than in developing
countries. Functional foods incorporated as part of the
daily diet provide the much needed alternative approaches
other than the existing anti hyperglycemic therapies. Use
the Plant fibers as supplement to anti diabetic therapies
which include Psyllium and pectin-the water soluble fibers
have proved to be effective in managing the blood sugar
levels as well improving the lipid profile another key
concern of the diabetics. Last year we had reported the
results of a short term double blind cross over study of
formulated premix staple with respect to its effect on
reducing blood glucose levels. The objective of the long
term clinical study presented here was to evaluate the blood
glucose response as well as the effect on lipid profile to a
meal containing a formulated premix staple during a long
term usage in non-insulin dependent type II diabetics. A
scientifically well formulated premix staple makes it
convenient and acceptable for the patients to incorporate it
as part of their daily meal. The premix is mixed with normal
wheat flour before making the rotis. A long term Randomized,
double blind cross over study to assess the Tolerability &
Efficacy of Psyllium based premixes mixed with daily staple
foods on levels of plasma glucose concentrations and lipid
profile were studied in Type II Diabetes Mellitus Subjects.
A 12 Point glucose profile, changes in lipid profile,
Glycated hemoglobin, c Peptide, insulin and BMI and body
weight were measured during the study period. The findings
of this clinical study can be summarized as follows. The
product had a significant effect on the glycemic control and
reduction in blood glucose levels in Type II diabetes
mellitus patients. The product had demonstrable effect on
the lipid profile and has the ability to reduce total
cholesterol, triglycerides, LDL cholesterol and cholesterol
to HDL ratio and at the same time aids in increasing the HDL
cholesterol. A measurable decrease was observed in the HbA1c
values during the period the study product is consumed. No
remarkable changes were seen in body weight and BMI. The
study product is safe and does not have any impact on the
insulin and c-peptide values, thus confirming that
metabolism is not affected by long term consumption of the
product. The study product did not have any noticeable side
effects during the consumption period as compared to the
commercial product. The taste of the product is as good as
the commercial product and the rotis made were softer than
the normal commercial wheat flour. Thus psyllium based
premixes staple food is an excellent form of functional food
supplement for Type II Diabetes Mellitus patients, when
consumed along with prescribed anti-diabetic medicines under
the observation and guidance of a medical practitioner.

Syed Mujtaba Hussain, Mishra SS. Kamineni Institute of
Medical Sciences, Narketpally.
Background.
Ajinomoto, monosodium glutamate (MSG), a central excitatory
neurotransmitter plays an important role in ischemic brain
damage and neurodegenerative disorders; its role in
depression is still inconclusive.
Aims and Objectives.
To study the
role of MSG on motor coordination &depression in albino
mice.
Materials and Methods.
Four groups
of Albino mice (n = 6), weighing more than 25gms were
selected and subjected to various tests for motor
coordination (Rotarod test, catatonic response time and hang
test) and depression (forced swimming test and tail
suspension test). Group1,2,3 received monosodium glutamate
in 0.5gm,1gm and 2gm/day orally. All the tests were repeated
after 1 week of administration. The animals were weighed
before & after the study.
Results.
The mean of
average time in Rotarod test increased for group1
(23.6-40.4sec) and group2 (10.4-45sec) & catatonic response
time decreased for group1 (28.8-17.0sec) & group2
(16.6-11.25sec). Group3 showed decrease in Rotarod test
(15.8-3sec) & increased catatonic response time (18.8-46.2).
Hang test for neuromuscular strength remained unchanged. The
immobility time for 5minutes in Tail suspension test
increased for all groups, Group1 (176.2-180.8sec) group2
(160.2-273.8sec) group3 (95-300sec). The immobility time in
forced swimming test for 5min increased, Group1
(50-75.2sec), Group2 (130-166sec), Group3 (97.5-186.2sec).
Weight increased in all groups. The animal one from each
group were sacrificed and sent for histopathological test.
The motor coordination has improved in group1&2 but shows
severe deterioration in group3 . All the groups showed signs
of depression. Results were analyzed by paired ‘t’ test and
were significant.
Conclusion.
MSG produced
neurotoxicity & depression in albino mice.

Abstract.
With the
burgeoning bioinformatics and proteomics studies in
metabolic disorders including insulin resistance and
diabetes mellitus, innovative methods for clustering of data
obtained have become imperative. Multiple protein sequence
alignments in general rely on conventions regarding the
score of a multiple alignment in pair wise fashion. With the
increase in the number of sequences, the run time of
sequencing expands exponentially. To address a possible
solution to this problem, this paper presents multiple
sequence alignment method using variant threshold valued
nearest neighbor clustering algorithm. This algorithm
clusters similar sequences at one time. BLAST has been used
to annotate the clusters generated by variant threshold
valued nearest neighbor clustering algorithm. The proposed
method of clustering and annotating with BLAST consists of
the following steps (1) Pair wise alignments of sequences
through probabilistic assumptions (2) Generate the (optimal)
distance matrix (3) Clustering the sequences with variant
threshold valued nearest neighbor clustering algorithm (4)
Annotating the protein clusters with BLAST. The performance
of the proposed system was evaluated with 40 genesequences
in a TCA cycle (a citrate cycle) of bacteria. The system
generated 11 clusters and found the longest subsequences of
each cluster, which are biologically significant.
Computational methods to Mine Knowledge from
Microarrays.
Karteeka Pavan K, Allam Appa Rao, Sridhar GR.
Microarrays are made it possible to simultaneously monitor
the expression profiles of thousands of genes under various
experimental conditions. The study of gene expression
profiling of cells and tissue has become a major tool for
discovery in medicine. Microarray experiments allow
description of genome-wide expression changes in health and
disease. Such gene expression information can be used in
medicine for comparing clinically relevant groups (eg.
healthy vs diseased), uncovering new subclasses of diseases,
and predicting clinically important outcomes, such as the
response to therapy and survival. Analysis of gene
expression data has proved to be a useful tool for
identifying coexpressed genes, biologically relevant
groupings of genes and samples. In this paper we present the
computational methods in Microarray analysis to extract the
biological information, clusters the gene expression data
using Automatic Generation of Merge factor for ISODATA -
AGMFI developed by us and compares the results with K-means.
Comparative Genomics and Clustering of Diabetes related
Proteins.
Bhramaramba R , Allam Appa Rao, Vijaya Kumar V,
Sridhar GR.
The objective of the study is to find the
organisms in which most of the Diabetes related proteins are
present and to find the clustering among them using
Histograms and bivariate plots. Protein Data has been taken
and attributes calculated using C software and analysis done
using Statistica package. In Diabetes related proteins it
was found that humans have orthologs in House Mice and
Norway Rat and hence there exist common Diabetes related
proteins though the length varies slightly across the
organisms (mammals). It can be inferred from the bivariate
plots that House Mice and Norway Rat cluster and are similar
in terms of the protein attributes and differ from that of
Human Sample.
Neural network (MLP) Clinical Decision Support System to
predict WellBeing in Diabetes. Narasinga Rao MR, Sridhar GR, Madhu K, Allam Appa Rao.
We have developed a neural network system which is trained
to predict the well being in diabetes, using data generated
in real life. We developed a Multi Layer Perceptron Neural
Network model, which had been trained by back propagation
algorithm. Data was used from a cohort of 241 individuals
with diabetes. We used age, gender, weight, fasting plasma
glucose as a set of inputs and predicted measures of
well-being (depression, anxiety, energy and positive
well-being). With five inputs (age, sex, weight, fasting
plasma glucose, bias), four outputs are four (depression,
anxiety, energy and positive well-being) the momentum rate
was 0.9, the learning rate 0.7, using a sample of 50. the
maximum individual error is 0.001. When the number of
iterations were 500, number of hidden layers 1 and the
number of units in the hidden layer 6, the normalized system
error was 470.57. With input samples of 100,150 and 200,
keeping the other variables constant, the normalized system
error was 419.61, 359.67 and 332.32 respectively. Similar
values are found for the normalized system error when the
number of units in the hidden layer have been increased to
7,8 and 9 respectively. With two hidden layers, and with
each hidden layer containing 6,7,8,9,10,11 units for the
samples 50, 100, 150 and 200 , the same values of normalized
system error was found.
Conclusion.
We have
developed a prototype neural network model to predict the
psychosocial well-being in diabetes, when biological or
biographical variables are given as inputs. When greater
data was fed real data to the system, the normalized system
error can be reduced.
Comparison of secondary structure of Butyrylcholinesterase (BchE)
using in silico methods.
Sridhar GR, Kudipudi Srinivas, Allam Appa Rao, Boyidi
Poorna Satyanarayana, Nageswar Rao K, Srinubabu G.
Butyrylcholinesterase has a well established pharmacogenetic
role in the hydrolysis of muscle relaxant succinylcholine.
But its physiological roles are unclear. It was shown to
modulate the expression of insulin resistance syndrome. In
the current insilico work we delineated the secondary
structure of the enzyme and compare it with other proteins
of similar structures. Using the amino acid sequences of
BchE, we obtained the secondary structure output using the
SOPM tool. From the PDB database we compared the secondary
structure of BchE with those having 65% or more similarity.
The proteins are present in both the cytoplasm,
extracellular compartment and cytoplasmic membranes. In
summary we compared the predicted secondary structure of
butyrylcholinesterase and obtained 13 proteins with at least
65% similarity that are found in the cytoplasm and
extracellular regions, with catabolic, synthetic, electron
transport and immune processing.

Insulin is a
hormone traditionally believed to occur only in the animal
kingdom, not in plants. We performed a bioinformatics study
of plant genomes and observed that sequences similar to
animal insulin exist in cow pea, jackbean and bauhinia
purpurea. We constructed phylogenetic tree of the different
insulins. In conclusion insulin like molecules exist in the
plant kingdom and may be responsible for plant development
and other as yet unknown metabolic functions. In addition
they may be responsible for some of the actions of plant
extracts for their antidiabetic properties.

The twin
epidemic of diabetes and obesity pose daunting challenges
worldwide. The dramatic rise in obesity-associated diabetes
resulted in an alarming increase in the incidence and
prevalence of obesity, an important complication of
diabetes. Differences among individuals in their
susceptibility to both these conditions probably reflect
their genetic constitutions. The dramatic improvements in
genomic and bioinformatic resources are accelerating the
pace of gene discovery. It is tempting to speculate the key
susceptible genes/proteins that bridges diabetes mellitus
and obesity. In this regard, we evaluated the role of
several genes/proteins that are believed to be involved in
the evolution of obesity associated diabetes by employing
multiple sequence alignment using ClustalW tool and
constructed a phylogram tree using functional protein
sequences extracted from NCBI. Phylogram was constructed
using Neighbor-Joining Algorithm, a bioinformatic tool. Our
bioinformatic analysis reports resistin gene as ominous link
with obesity associated diabetes. This bioinformatic study
will be useful for future studies towards therapeutic
inventions of obesity associated type 2 diabetes.
Computational analysis of microsatellites in colon cancer
genes.
Vamsidhar Enireddy, Kishore Gunna, Allam Appa Rao, Sridhar G
R, Suresh B Mudunuri.
Carcinoma of the colon, which has been recognized to
co-exist with metabolic syndrome and type 2 diabetes, is
also a major cause of death, appearing at a younger age in
Asian Indians. It results from an interaction of genes and
environmental changes. Mutations of MSH gene is a well known
factor in the pathogenesis. Earlier we showed that
microsatellite regions were associated with mutations in the
MSH gene. Here we extended the study to include all known
genes known to be associated with colon cancer and
identified microsatellite regions in each. There were no
known mutations in any of the other genes in the HGMD (Human
genome mutation database) except for MSH gene. Therefore, in
the presence of microsatellite regions, further studies in
the association of mutations of genes and colon cancer must
evaluate for mutations that might occur at the
microsatellite regions.
Computational Analysis of Repeat Patterns in Diabetic Genes.
Suresh B Mudunuri, Allam Appa Rao, Sridhar G R, Department
of Computer Science and Systems Engineering, Andhra
University, Visakhapatnam.
Human genome sequence contains a large number of small
repeat patterns that vary in number and size.
Microsatellites are one such type of repeats of pattern size
1-6 that repeat tandemly. These repeats are known to be
responsible for causing various diseases such as neuro-degenerative
diseases and are also responsible for evolution of the
organisms. These microsatellites are more prone for
mutations (changes) in their sequence leading to formation
of abnormal protein/no protein which in turn result in
various diseases. Analysis of these repeats invivo is
expensive and time consuming. So, we made a simple
computational analysis of few genes responsible for causing
diabetes and the results are satisfactory. We found that the
human insulin promoter factor 1 (IPF-1) gene gets mutated
due to the presence of microsatellites and thus causing
diabetes in some cases. We have collected the mutations of
these genes from Human Gene Mutation Database and the
microsatellites extracted using the tool Imperfect
Microsatellite Extractor (IMEx) were mapped and found
interesting facts. Our analysis revealed that the InsCCG243
(Proline insertion) mutation that is known to inhibit the
insulin production, is due to microsatellite polymorphism.
We analyzed 9 known mutations in the IPF-1 gene (excluding
the silence mutations) and found out except one (R197H), all
the other mutations (C18R, Q59L, Pro63fsdel, D76N, G212R,
E224, P239Q, InsCCG243) fall outside the domain region. The
mutation falling in the domain region seems to be inducing a
change in the secondary structure and resulting in change or
absence of protein function. We report that 4 out of these 9
mutations fall inside the microsatellite tracts and thus
indicating a positive role of microsatellites in
mutagenesis. A complete analysis of all the human genes
which directly or indirectly cause diabetes needs to be done
to get much more interesting results.

Abstract.
Cluster
analysis of DNA micro array data is described that uses
statistical algorithms to arrange the genes according to
similarity in patterns of gene expression and the output
displayed graphically. Hierarchical Clustering is a
multivariate tool often used in phylogenetics, comparative
genomics to relate the evolution of species. The patterns
seen in microarray expression data can be interpreted as
indications of the status of the genes responsible in Type2
Diabetic nephropathy in Peripheral Blood Cells. Out of 415
genes totally expressed in the 3 DNA chips came to
conclusion that only 116 genes expressed in T2DN and in that
only 50 are functional genes. These 50 functional genes are
responsible for diabetic nephropathy, out of these 50, some
of the genes which are more expressed and responsible are
AGXT: Alanine-glyoxylate aminotransferase, RHOD: Ras homolog
gene family, CAPN6: Calpain 6, EFNB2: Ephrin-B2, ANXA7:
Annexin A7, PEG10: Paternally expressed 10, DPP4: Dipeptidyl-peptidase
4 (CD26, adenosine deaminase complexing protein 2), ENSA:
Endosulfine alpha, IGFBP2: Insulin-like growth factor
binding protein 2, 36kDa, CENPB: Centromere protein B,
80kDa, MLL3: Myeloid/lymphoid or mixed-lineage leukemia 3,
BDNF: Brain-derived neurotrophic factor, EIF4A2: Eukaryotic
translation initiation factor 4A, isoform 2, PPP2R1A:
Protein phosphatase 2 (formerly 2A), regulatory subunit A,
alpha isoform.
50 genes and
their nucleotide sequences are taken from NCBI and a
phylogenetic tree is constructed using CLUSTAL W and the
distances are
closer to each other concluding that based on
the sequence similarity
and evolution the genes are
expressed similarly.

Objective.
To obtain
meaning from the flood of genomic data by using data mining
techniques namely, principal component analysis and
Discriminant Analysis pertaining to a sample diabetes
related proteins obtained from a database.
Methods.
C software has been used to calculate the
protein attributes.
Discriminant
Analysis and Principal Component Analysis have been
performed using SPSS 16.0 Software. Protein Sample has been
taken from www.genecards.org.
Results.
Comparative analysis of genome sequences was
performed to unravel the complexities of biological
processes by using data mining tools. Almost all human genes
known to be associated with disease have rat orthologs.
About 30% of rat genome aligns only with the mouse. Globally
the mouse genome is about 14% smaller than the human
genome. Eighty percent of mouse proteins had strict 1:1
orthologs in human genome. The rat genome was smaller than
human, but larger than the mouse. Both however encode a
similar number of genes. The use of rat and mouse for
comparison with human proteins is appropriate because
sufficient evolutionary distance exists between rodents and
humans.
Conclusion.
principal
component analysis could assist in assigning function to
diabetes related proteins, which are being identified at an
increasing pace. Discriminant Analysis technique proves that
among the three species under study human beings distinctly
differs from the other two species house mice and Norway Rat
in respect of their protein attributes.
Analysis
from all methods showed that there was a clustering of
proteins from humans, which was different from that of mouse
and rat; those from the latter two animals clustered
together.
Ceramide
Mediates Glucolipotoxicity of the Pancreatic Beta Cell.
Anjan Kowluru. Department of Pharmaceutical Sciences,
Wayne State University, Detroit.
The sphingolipid ceramide [CER] has been recognized as
an important mediator of a variety of cellular responses
including cell death via apoptosis. Intracellular
generation of CER could result either from de novo
synthesis from fatty acids or from hydrolysis of
sphingomyelin. Available evidence suggests that chronic
exposure of isolated beta cells to high levels of glucose
[i.e., glucotoxicity], lipids [i.e., lipotoxicity] or both
[i.e., glucolipotoxicity] leads to their metabolic
dysfunction and demise via apoptosis. However, the
precise mechanisms underlying dysregulation of beta cells
under glucolipotoxic conditions remain less understood.
Herein, we report a significant increase in the CER-activated
protein phosphatase activity in isolated beta cells under
glucolipotoxic conditions. This results in dephosphorylation
and subsequent inactivation of key cellular proteins,
including mitochondrial Bcl2 leading to mitochondrial
dysfunction [e.g., loss in membrane potential and release of
cytochrome C into the cytosol] and demise of the beta cell.
These findings were confirmed in islets derived from the ZDF
rat, a model for type 2 diabetes. Further, we also observed
a significant increase in CER-induced generation of reactive
oxygen species and the associated oxidative stress in
isolated beta cells under glucolipotoxic conditions thereby
leading to mitochondrial dysfunction. Based on these data,
we propose that intracellular generation of CER under
glucolipotoxic conditions represents one of the signaling
steps leading to mitochondrial dysfunction and demise of the
beta cell culminating in the onset of diabetes.

132
consecutive youth onset diabetics (age of onset <30 years)
were studied for serological markers of islet cell
auto-immunity, associated thyroid auto-immunity as well as
co-existing malnutrition and calcific pancreatropathy. 37%
had classical type I Diabetes Mellitus. 32% were Ketosis
Resistant Diabetes of the Young (KRDY), 11% were having
Fibro-Calcific Pancreatopathy (FCPD) and 7% had auto-immune
polyglandular syndrome (coexisting islet cell and thyroid
autoimmunity). 22% of type I and 30% of auto-immune
polyglandular auto-immunity related diabetics showed both
GAD65 and
IA–2 antibody positivity, whereas only 4.7% of KRYD showed
GAD65 +
IA–2 Ab positivity (p<0.001). However, GAD65
Ab lone +vity was shown by 38% of KRYD, which
was significantly more than the 14.2% & 10% positivity seen
in type I and auto-immune polyglandular auto-immune types
respectively. The FCPD group showed GAD65 &
IA–2 Ab positivity in 14.2% and GAD Ab alone positivity in
7.1% 26 & 60% respectively of type I and auto immune
polyglandular syndrome groups had thyroid microsomal Ab +vity.
Type I group had significantly less C-peptide response to
glucagon when compared to the ketosis resistant and
auto-immune polyglandular groups. Type II youth onset group
studied tested negative for islet cell auto immunity
markers. Thus, 4 out of 5 of youth onset diabetic groups
studied demonstrate serological markers of islet cell
auto-immunity.
