Abstract Background: Type 2 Diabetes Mellitus (T2DM) is a chronic metabolic condition with various genetics and environmental influences that affects the capacity of the body to produce or use insulin resulting in hyperglycemia, which may lead to variable complications. It is one of the world’s rising health problems. There is emerging evidence that some genetic polymorphisms can impact the risk of evolving T2DM. We try to determine the relationship of (rs7903146) variant of the Transcription factor 7-like 2 (TCF7L2) gene with T2DM and its microvascular complications.Methods and Results: This case-control study included 180 subjects: 60 diabetic patients without complications, 60 diabetic patients with microvascular complications and 60 matched healthy controls. Genotypes of rs7903146 (C/T) SNP in the TCF7L2 gene were evaluated by real-time polymerase chain reaction via TaqMan allelic discrimination. Logistic regression was used to detect the most independent factor for development of diabetes and diabetic microvascular complications. Variant homozygous TT and heterozygous TC genotypes were significantly increased in diabetic without complications and diabetic with complications groups than controls (p=0.003, 0.001) respectively. The T allele was more represented in both patient groups than controls with no significant difference between patient groups. TT genotype as well as T allele was significantly associated with increased T2DM risk.Conclusion: The T allele of rs7903146 polymorphism of TCF7L2 confers susceptibility to development of T2DM. However, no significant association was found for diabetic complications.

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.

Microvascular complications of Type 2 Diabetes Mellitus (T2DM), (retinopathy and nephropathy) have a similar etiopathogenetic mechanism besides genetic predisposition. Even though these two complications frequently co-exist, their frequency varies. The association of these two signicant complications and their coexistence needs a relook. To study prevalence of retinopathy and nephropathy in Type 2 diabetes mel Aim: litus. Comparison of diabetic retinopathy and nephropathy in Type 2 diabetes mellitus and its correlation of diabetic retinopathy and nephropathy with duration of illness and various risk factors that affects development, progression and severity of diabetic retinopathy and nephropathy. 100 diabetic patients were taken up for study for a period of one year meeti Methodology: ng the criteria for the present study. Detailed history was taken from patient and meticulous examination was done of all patients with special emphasis on renal and ophthalmic symptoms. Clinical data and investigation prole was tabulated. Statistical analysis was done. Among 100 patients, 22 had diabetic retinopathy. Among patients with diab Results & Conclusion: etic retinopathy, 68.18% patients had positive family history. Among 100 patients, 32 had diabetic nephropathy, mean FBS was 207 mg%, PPBS was 317.8 mg% and mean HbA was 9.2%. Among patients with diabetic retinopathy, mean FBS was 211 mg%, PPBS was 324.9 1c mg%, HbA was 9.5%. From this study it is found that diabetic nephropathy starts earlier than retinopathy. In this study 1c hypertension was found to accelerate progression into nephropathy and retinopathy.

Objective. The interaction between advanced glycation end products and their cellular receptor (RAGE) has an important role in the pathogenesis of diabetic microvascular complications. The aim of this study was to investigate the relationship between the 2184A/G polymorphism in the RAGE gene and diabetic nephropathy in Chinese Han patients with type 2 diabetes mellitus. Methods. A total of 868 patients with type 2 diabetes mellitus (486 without and 382 with diabetic nephropathy) were enrolled in this study. The genotype and allele frequencies of the 2184A/G polymorphism were detected using the polymerase chain reaction-restriction fragment-length polymorphism method. Results. The G allele and AG + GG genotype frequencies in patients with diabetic nephropathy were significantly lower than those in patients without diabetic nephropathy (P=0.001 and P=0.005, resp.). After adjustments for possible confounders, multivariate logistic regression analyses showed that the 2184A/G polymorphism was independently associated with diabetic nephropathy (OR = 0.46, 95% CI: 0.22–0.92, P=0.028). Conclusions. Our study indicated that the 2184A/G polymorphism in the RAGE gene was significantly associated with diabetic nephropathy in Chinese Han patients with type 2 diabetes.

Background: Dyslipidemia has a varying pattern among the male and female patients of type 2 diabetes mellitus (DM).Methods: This study was conducted in the out-patient department (OPD) of department of medicine at GMERS, Patan, Gujarat from July 2020 to December 2020 for a period of six months. Fasting blood sugar, hemoglobin A1c (FBS, HbA1c) lipid profile triacylglycerol-triglyceride, total cholesterol, low density lipoprotein cholesterol and high-density lipoprotein cholesterol (TG, TC, LDL-C, and HDLC) were measured. Statistical analyses were performed with the SPSS software program.Results: A total number of 200 type 2 DM patients (100 males and 100 females) attending to GMERS OPD were recruited in this study. Blood sugar was higher than normal in both male and female (FBS=142.44±36.21, 146.40±41.49 respectively). TG level was also higher in two groups of study subjects with female level slightly more than male (164.99±67.1and 138.21±70 respectively) with no significant difference between the groups (p>0.05).Total cholesterol and LDL-C level was within normal physiological level in both groups, where-as these levels were higher in female in comparison to male (TC=198.07±40.82 and 169.5±36.13 respectively, LDLC=118±34 and 99±27, respectively), showing significant difference between the groups (p=0.014). HDL-C was not below normal in both male (41±5.4) and female (43.99±4.31); however, HDL-C was slightly higher in female than male and the difference was significant (p=0.0129).Conclusions: Dyslipidemia was noticed in a greater proportion of female diabetic patients than male diabetic patients.

In type 2 diabetes mellitus, there are changes in hemostasis components, including overexpression of PAI-1. By these facts, the authors are interested in conducting the study of PAI-1 level in diabetic patients with and without foot ulcer. Methods: The sample of this research was collected cross-sectionally on 20 type 2 diabetic patients with foot ulcer and 20 without foot ulcer. Blood samples were taken to measure serum PAI-1 level, complete blood count and hemostasis screening test. Results: Statistical analysis showed there are significant differences in hemoglobin, trombosit, Fibrinogen and D-dimer levels in the ulcer and non-ulcer groups but no significant difference in PAI-1 level. Conclusions: No higher PAI – 1 level were found in diabetic foot ulcer group than those without diabetic foot ulcer. There was no significant difference between PAI-1 level and grade of diabetic foot ulcer.
