Type 2 diabetes mellitus (T2DM) is a global problem. Recent studies confirmed the association of genes and different single nucleotide polymorphisms with T2DM occurrence and progress. This study was aimed to estimate the vitamin D receptor (VDR) gene polymorphism in Type 2 Diabetes Mellitus patients in Erbil city. The results showed that the Body mass index (BMI), Systolic blood pressure and Diastolic blood pressure were significantly higher in the diabetic group compared to the control group (P<0.05). In addition, the percent of Glycated hemoglobin (HbA1c), Fasting blood glucose (FBG), and Homeostatic model assessment for insulin resistance (HOMA-IR) were significantly higher in the diabetic group compared to the control group (P<0.05). Among different parameters of lipid profile, only Low-density lipoprotein (LDL) was significantly higher in the diabetic group compared to the control group. It was found that FBG value was significantly higher in patients with GA and AA genotypes of BsmI compared with healthy controls. Patients with the GA genotype of BsmI had a higher value of triglyceride compared to healthy individuals. Patients with all ApaI genotypes had higher FBS values than controls. There were not observed any signi?cant associations among the BsmI and ApaI polymorphisms and the risk of T2DM. In conclusion, no evidence was found for the association between two VDR polymorphisms and T2DM patients in Erbil city.

Abstract Background In patients with type 2 diabetes mellitus (T2DM) the inflammatory and metabolic responses to epigallocatechin-3-gallate (EGCG) are unknown. Objectives Evaluate the impacts of EGCG on metabolic factors and some biomarkers of stress oxidative in patients with T2DM. Methods In this randomized, double-blind, placebo-controlled trial, 50 patients with T2DM consumed either 2 tablets (300 mg) EGCG (n=25) or wheat flour as placebo (n=25) for 2 months. The total antioxidant capacity (TAC), interleukin-6 (IL-6), lipid profile, mean arterial pressure (MAP), atherogenic index of plasma (AIP) were evaluated before and after the intervention. Results The finding of present study exhibited a significant increase in the serum levels of TAC after the EGCG supplementation (p=0.001). Also, in compare with control group, the mean changes of TAC were significantly higher in supplement group (p=0.01). In intervention group, a significant decrease was observed in the mean levels of triglyceride, total cholesterol, diastolic blood pressure (DBP), AIP, and MAP (p<0.05). Taking EGCG resulted in the mean changes of total cholesterol, MAP and DBP were significantly lower in compare with control group (p<0.05). Conclusions This study recommended that EGCG supplementation may be improved blood pressure, lipid profile, AIP, and oxidative status in patients with T2DM.

  Objective: Vitamin D receptor (VDR) mediated Vitamin D signaling is important for expression of insulin gene and glucose transporters, which help in glucose uptake by cells. Current evidence suggests that four common polymorphisms (FokI, BsmI, ApaI, TaqI) of VDR gene are associated with Type 2 diabetes mellitus (T2DM) in different populations. However, there is a scarcity of data on VDR polymorphisms from Indian population.Methods: In the current study, total genomic DNA was isolated from 100 well-characterized T2DM patients and 100 healthy controls. We investigated the prevalence of FokI and ApaI polymorphisms in VDR gene of these patients by polymerase chain reaction-restriction fragment length polymorphism-based method. Taking help of our previous published data on TaqI and BsmI polymorphisms in same patients, the haplotype study was also conducted. Statistical analysis of data was performed using SPSS 21.0 software. Haplotype and linkage disequilibrium analysis was performed by Haploview software.Results: Both the wild (TT) and mutant (CC) genotype of FokI polymorphism showed a significant difference between patients and controls (p<0.001 and p<0.001, respectively). The frequency of mutant allele (C) was also significantly higher in T2DM patients than the controls (p<0.001). In case of ApaI, frequency of wild (GG) and mutant (CC) genotype was significantly different in patients and controls (p=0.017 and p=0.034). As per haplotype analysis, the CACT haplotype was predicted to be of significance in patients and consists of mutant alleles of three polymorphisms (FokI, BsmI, ApaI). Conclusion: Our study supports the association of FokI and ApaI polymorphism in T2DM. The haplotype analysis also indicates that the combinations of mutant allele of different VDR polymorphisms are probably responsible for increased susceptibility of these individuals toward T2DM.

OBJECTIVE: The rate of reduction of nocturnal blood pressure (NBP) is lesser than normal in patients with type 2 diabetes mellitus (type 2 DM). Hyperhomocysteinemia (HHC) disrupts vascular structure and function, no matter the underlying causes. The risk of development of vascular disease is greater in diabetic patients with hyperhomocysteinemia than in patients with normal homocystein levels. The aim of the study was to investigate whether there are differences of homocystein levels in dipper and non-dippers patients with type 2 DM. SUBJECTS AND METHODS: We compared 50 patients (33 females, 17 males) with type 2 DM and 35 healthy individuals (18 females, 17 males ) in a control group. Ambulatory blood pressure monitoring (ABPM) was performed and homocysteine levels were measured in all patients. RESULTS: We found that the percentage of non-dipper pattern was 72% in patients with type 2 DM and 57% in control group. In diabetic and control individuals, homocystein levels were higher in non-dipper (respectively 13.4 ± 8.1 µmol/L and 11.8 ± 5 µmol/L) than in dipper subjects (respectively, 11.8 ± 5.8 µmol/L and 10.1 ± 4.2 µmol/L), but there was no significant difference between the two groups (respectively, p = 0.545, p = 0.294). CONCLUSION: In both groups, homocystein levels were higher in non-dipper than in dipper participants, but there was no significant difference between the groups. High homocystein levels and the non-dipper pattern increases cardiovascular risk. Therefore, the relationship between nocturnal blood pressure changes and homocystein levels should be investigated in a larger study.

ABSTRACT Background: Type 2 Diabetes Mellitus is a multifactorial syndrome with severe complications. Oxidative stress is accepted as a causal factor of chronic complications Aim: To demonstrate alterations in oxidative stress after metabolic surgery. Methods: Twenty-four 2-day-old Wistar rats were used. In 16, Type 2 Diabetes Mellitus was induced by 100 mg/kg streptozotocin injection. The development of diabetes was confirmed after 10 weeks using an oral glucose tolerance test. Eight diabetic rats composed the diabetic surgical group; the remaining eight composed the diabetic group. Eight animals in which diabetes was not induced formed the clinical control group. The Marchesini technique was used in the diabetic surgical group. After 90 days, the rats were sacrificed, and the oxidative stress markers were measured. Results: Thiobarbituric acid reactive substances, superoxide dismutase and catalase were significantly reduced in the diabetic surgical group compared to the diabetic group. Conclusion: The duodenojejunostomy was effective in controlling the exacerbated oxidative stress present in diabetic rats.
