Introduction: Today the prevalence of type 2 diabetes reached an epidemic level. It is known that type 2 diabetes could only be prevented before the manifestation, during the “prediabetic” state, urging the development of diagnostic tests to recognize the group at risk in time. Aim: The authors explored metabolic differences between healthy, normal glucose tolerant, normal insulin resistant females having first degree relatives with and without type 2 diabetes. Method: Healthy, normal insulin sensitive females without (n = 26) and with (n = 18) type 2 diabetic relatives were investigated. Results: Healthy females with first degree diabetic relatives had lower low density lipoproteins and higher high density lipoproteins as well as higher glucose and insulin levels at the 120 min of oral glucose test as compared to those without first degree diabetic relatives. Conclusions: These results suggest that the appearance of insulin resistance is preceded by hepatic insulin resistance and impaired lipid metabolism in the symptom-free prediabetic period of genetically suceptible females.

Background: Accumulating evidence suggests that adiponectin, a major adipocyte secretory protein, has insulin-sensitizing and anti-atherogenic properties and protects against later development of type 2 diabetes. We investigated the association of adiponectin with insulin resistance, blood lipids and type 2 diabetes in non obese central Indian population.Methods: Anthropometric and biochemical parameters were measured in 149 (81 male and 68 female) newly diagnosed non obese type 2 diabetic patients and 157 (85 male and 72 female) age and body mass index (BMI) matched controls.Results: Adiponectin level (p<0.0001) was significantly lower in the diabetic group than in non diabetic control. In an age, gender and BMI adjusted model, adiponectin level was significantly negatively correlated with waist circumference, waist to hip ratio, systolic blood pressure, fasting insulin, homeostasis model assessment-insulin resistance (HOMA-IR) (p= 0.0034), HbA1C, total cholesterol, LDL-cholesterol, and triglycerides (p<0.0001) and positively correlated with HDL-cholesterol (p =0.0014) in non obese type 2 diabetic group. However, there was no significant correlation between adiponectin and glucose in this study. In stepwise linear regression analysis, adjusted for potential confounder, significant inverse association was observed between serum adiponectin level and HOMA-IR (p = 0.0001). In multivariate logistic regression model, adjusted for age, gender, BMI, waist circumference, and waist-hip ratio, lower adiponectin was independently associated with the presence of type 2 diabetes (p<0.0001).Conclusions: Lower adiponectin levels in non obese type 2 diabetic patients were significantly related to the increased insulin resistance, dyslipidemia, and presence of type 2 diabetes, independently of overall and abdominal adiposity, thereby suggesting a direct link between adiponectin and carbohydrate and lipid metabolism in human.

Two-dimensional difference gel electrophoresis (2-D DIGE)-based proteome analysis has revealed intrinsic insulin resistance in myotubes derived from type 2 diabetic patients. Using 2-D DIGE-based proteome analysis, we identified a subset of insulin-resistant proteins involved in protein turnover in skeletal muscle of type 2 diabetic patients, suggesting aberrant regulation of the protein homeostasis maintenance system underlying metabolic disease. We then validated the role of the ubiquitin-proteasome system (UPS) in myotubes to investigate whether impaired proteasome function may lead to metabolic arrest or insulin resistance. Myotubes derived from muscle biopsies obtained from people with normal glucose tolerance (NGT) or type 2 diabetes were exposed to the proteasome inhibitor bortezomib (BZ; Velcade) without or with insulin. BZ exposure increased protein carbonylation and lactate production yet impaired protein synthesis and UPS function in myotubes from type 2 diabetic patients, marking the existence of an insulin-resistant signature that was retained in cultured myotubes. In conclusion, BZ treatment further exacerbates insulin resistance and unmasks intrinsic features of metabolic disease in myotubes derived from type 2 diabetic patients. Our results highlight the existence of a confounding inherent abnormality in cellular protein dynamics in metabolic disease, which is uncovered through concurrent inhibition of the proteasome system.

Background: Type 2 diabetes is characterized, beyond the insulin resistance, by polyhormonal resistance. Thyroid hormonal resistance has not yet been described in this population of patients. Metformin is used to decrease insulin resistance, and at present it is assumed to influence the effect of triiodothyronine, as well. Methods: In this open label, pilot, hypothesis generating, follow-up study 21 patients were included, all of them euthyroid with drug naïve, newly diagnosed type 2 diabetes. Before and after four weeks of metformin therapy fructosamine, homeostasis model assessment for insulin resistance (HOMA-IR), thyroid hormones, T3/T4 ratio, and TSH, as well as blood pressure and heart rate using ambulatory blood pressure monitor were measured. We also conducted an in vitro study to investigate the possible mechanisms of T3 resistance, assessing T3 induced Akt phosphorylation among normal (5 mM) and high (25 mM) glucose levels with or without metformin treatment in a human embryonal kidney cell line. Results: Metformin decreased the level of T3 (p<0.001), the ratio of T3/T4 (p=0.038), fructosamine (p=0.008) and HOMA-IR (p=0.022). All these changes were accompanied by an unchanged TSH, T4, triglyceride, plasma glucose, bodyweight, blood pressure and heart rate. In our in vitro study, T3 induced Akt phosphorylation decreased in cells grown in 25 mM glucose medium compared to those in 5 mM. Metformin could not reverse this effect. Conclusion: Metformin seems to improve T3 sensitivity in the cardiovascular system in euthyroid, type 2 diabetic patients, the mechanism of which may be supracellular.

Background. Offspring of type 2 diabetic patients are at a high risk of type 2 diabetes. Information on diabetes genetic susceptibility and prevention should be supplied to the offspring.Methods. A six-page booklet on diabetes genetic susceptibility and prevention was distributed to 173 patients who ere ordered to hand it to their offspring. The patients answered a self-administered questionnaire on booklet delivery and attitudinal and behavioral changes toward diabetes and its prevention in themselves and their offspring.Results. Valid responses were obtained from 130 patients. Forty-nine patients had actually handed the booklet. Booklet induces more relief than anxiety. From the patient's view, favorable attitudinal and/or behavioral changes occurred in more than half of the offspring who were delivered the booklet.Conclusion. The booklet worked effectively on attitudes and behaviors toward diabetes and its prevention both in patients and their offspring. However, the effectiveness of patients as information deliverers was limited.

BACKGROUND Type 2 diabetes mellitus is common in the Indian population and awareness regarding the disease and its complications is low among the patients with diabetes. There is lack of studies regarding awareness of complications of diabetes among type 2 diabetic patients. The purpose of this study was to assess the awareness of diabetic complications among type 2 diabetic patients. METHODS This is an institutional based observational study. The sample comprised of 150 adult patients with type 2 diabetes mellitus who underwent treatment in the Department of Medicine, Medical College Kottayam and the patient’s age ranged from 18 - 77 years. RESULTS Majority of patients were in the age group 38 to 57 and the sample comprised of 56 % males and 44 % female patients. Out of 150 patients involved in the study, 120 patients (80 %) were aware of the complications of diabetes mellitus. Among the male patients, 70 (83.33 %) and among females, 50 (75.75 %) were aware of the complications in diabetes. In the study sample, 92 (61.33 %) were aware of the foot problems, 120 patients (80 %) were aware of renal complications, 91 patients were aware regarding eye problems of diabetes, 38 (25.33 %) regarding development of hypertension, 62 (41.33 %) regarding heart attack, 42 (28 %) patients were aware regarding development of stroke and 78 patients (52 %) had awareness regarding occurrence of recurrent infections. CONCLUSIONS Awareness regarding diabetes and its complications is fairly good among the diabetic patients in Kerala. Awareness regarding all complications of diabetes was higher among males than females. Providing awareness to type 2 diabetic patients by various educational programs may be of further help to prevent complications and to decrease the mortality and morbidity in type 2 diabetes patients.
