MNS16A VNTR polymorphism of human telomerase gene: Elucidation of a gender specific potential allele associated with type 2 diabetes in Bangladeshi population

Background: Sex specific differences appear particularly relevant in the management of type 2 DM. Objective: We determined gender specific differences in cardio-metabolic risk, microvascular and macrovascular complications in patients with type 2 diabetes. Methods: Four hundred type 2 diabetes patients, males and females, matched for age and disease duration were recruited from the diabetes clinic. Relevant clinical and laboratory information were obtained or performed. Results: 190(47.5%) were male and 210 (52.5%) were female respectively. The mean age of the study population was 60.6 + 9.93 years. Women had higher prevalence of hypertension (and obesity. Mean total cholesterol was significantly higher in women but men were more likely to achieve LDL treatment goals than women (69.5% vs 59.0%, p<0.05). More women (47.1% & 31.4%) reached glycaemic goals of <10mmol/l for 2HPP and HBA1c of <7.0%. There were no gender differences in the distribution of microvascular and macrovascular complications (p>0.05) but women were more likely to develop moderate and severe diabetic retinopathy (p= 0.027). Conclusion: Women with T2DM had worse cardiometabolic risk profile with regards to hypertension, obesity and lipid goals. Men achieved therapeutic goals less frequently than did women in terms of glycaemia. Microvascular and macrovascular com- plications occurred commonly in both sexes.

Bangladeshi Population

Diabetes mellitus is a group of metabolic diseases characterized by high blood glucose levels that result from defects in insulin secretion or action or both. Some recent studies had shown that elevated level of C?reactive protein (CRP) and uric acid are involved in the pathogenesis of type 2 diabetes, regardless of other characteristics of subjects. Our aim was to investigate the association between CRP and uric acid levels with diabetes in Bangladeshi population. Two hundred type 2 diabetic subjects (male 110, female 90) and 60 non diabetic subjects (30 male, 30 female) were included in the study over six months. CRP and uric acid were measured by Latex Agglutination method and enzymatic colorimetric method, respectively. CRP was significantly higher (p < 0.01) in diabetic compared to non-diabetic subjects for both male and female subjects. The level of uric acid was also significantly higher in male and female diabetic subjects (p < 0.05 and p < 0.01) compared to non-diabetic subjects, respectively. In multiple regression analysis, CRP showed a positive association with uric acid and BMI in both diabetic and non-diabetic subjects. On the other hand, uric acid showed positive association with fasting blood sugar (FBS), diastolic blood pressure, HbA1c and CRP in case of diabetic subjects, but with age, BMI, CRP, HbA1c and creatinine in non-diabetic subject. Uric acid also shows a significantly (p < 0.001) positive Pearson correlation with CRP. These data strongly suggest that compared to non-diabetic subjects, diabetic subjects have significantly higher level of CRP and uric acid.

Control Study

Objective: Apolipoprotein B (APOB) plays an important role in the metabolism of cholesterol and impairment in its function can lead to cholesterol accumulation in the pancreatic islets. It can then reduce insulin secretion and lead to Type 2 diabetes (T2DM). The purpose of this study was to investigate the association of 3chr('39')APOB-VNTR polymorphism with plasma lipid profiles in T2DM individuals in Khorasan Razavi province, Iran. Materials and Methods: In this case-control study, 204 patients with T2DM and 207 non-diabetic volunteers were examined as a control group. All samples were analyzed for plasma lipid profiles. Genotypes were determined by PCR and electrophoresis. Differences in lipid variables between genotypes were assessed using one-way analysis of variance (ANOVA) with SPSS 20.0. Results: We found 18 different alleles of the APOB gene 3chr('39')VNTR comprising from 26 to 45 hypervariable elements (HVEs) in the control groups and 21 alleles ranging from 30 to 51 repeats in the T2DM patients. Short alleles (26 to 29 HVEs) were only in controls and large alleles (46 to 51 HVEs) were only in T2DM patients. Our results showed that in people with long HVE polymorphism, HDL-C levels decreased, but LDL-C increased. Therefore, longer alleles for T2DM are considered risk factors. It was also observed that the TC / HDL-C ratio was significantly lower in shorter genotypes than the longer genotypes in T2DM patients. Conclusion: It is concluded that 3chr('39')APOB-VNTR polymorphisms, especially longer alleles, affect plasma lipid levels in individuals with T2DM and are risk factors for this disease.

Gender Specific

Type-2 diabetes (T2D) and its cardiovascular complications are related to sex. Increasing evidence suggests that paraoxonase 1 (PON1) activity, an antioxidant enzyme bound to high-density lipoproteins (HDL), is implicated in the onset and clinical progression of T2D. Since we previously showed that PON1 is a sexual dimorphic protein, we now investigated whether sex might impact the relationship between PON1 and this chronic disease. To address this aim, we assessed PON1 activity in the sera of 778 patients, including controls (women, n = 383; men, n = 198) and diabetics (women, n = 79; men = 118). PON1 activity decreased in both women and men with T2D compared with controls (p < 0.05 and p > 0.001, respectively), but the change was 50% larger in the female cohort. In line with this result, the enzyme activity was associated with serum glucose level only in women (r = −0.160, p = 0.002). Notably, only within this gender category, lower PON1 activity was independently associated with increased odds of being diabetic (odds ratio (95% Confidence interval: 2.162 (1.075–5.678)). In conclusion, our study suggests that PON1-deficiency in T2D is a gender-specific phenomenon, with women being more affected than men. This could contribute to the partial loss of female cardiovascular advantage associated with T2D.
