Markers of inflammation in patents with type 2 diabetes and cardiovascular form of diabetic autonomous neuropathy

Aim. To determine the level of inflammation markers and their relation to endothelial dysfunction and insulin resistance in patents with type 2 diabetesmellitus and cardiovascular form of diabetic autonomous neuropathy. Materials and methods. A total of 87 patients aged 45-66 years were examined for blood insulin level, insulin resistance index (HOMA-IR), CRP,and anti-inflammatory cytokine (TNF-a, IL-1-beta, IL-6) levels. Endothelial dysfunction was estimated based on quantitative Willebrand factorassay. Vegetative disorders were detected from reflex cardiovascular ECG data. Results. The development of cardiovascular form of diabetic autonomous neuropathy in patents with type 2 diabetes depended on diabetes duration,quality of carbohydrate metabolism compensation, levels of hyperinsulinemia and insulin resistance. Mean levels of Willebrand factors andinflammation markers in patents with type 2 diabetes and overt vegetative dysfunction were significantly higher than in diabetic patients withoutautonomous neuropathy. Correlation analysis revealed significant correlation of CRP and IL-6 levels with results of standard ECG tests. Conclusion. Results of the study demonstrate chronic inflammation in patents with type 2 diabetes and cardiovascular form of diabetic autonomousneuropathy. Increased level of inflammation markers and its relation to severity of vegetative disorders and endothelial dysfunction confirm the roleof inflammation in pathogenesis of nervous co-morbidity in patents with type 2 diabetes

Genetic framework of type 2 diabetes mellitus

More than 100 genes associated with the risk of type 2 diabetes mellitus (T2DM) are now established. Most of them affect insulin secretion, adipogenesis and insulin resistance, but the exact molecular mechanisms determining their involvement in the pathogenesis of T2DM are not understood completely

Morphological and functional parameters of the heart and vessels in patients with type 2 diabetes mellitus and cardiovascular autonomic neuropathy

Objective. To evaluate morphological and functional parameters of the heart and vessels in patients with type 2 diabetes mellitus (DM2) and diabetic cardiovascular autonomic neuropathy (CAN). Materials and methods. A total of 139 patients with DM2 and hypertension (mean age: 53.1?4.9 years; mean duration of hypertension: 9.7?7.8 years) were included in this study. Based on cardiovascular autonomic function test results (electrocardiography, heart rate variability) patients were divided into 2 groups as follows: Group 1 included 40 patients without CAN and Group 2 included 99 patients with CAN. The control group comprised 30 patients with hypertension and normal carbohydrate metabolism (mean age: 53.1?6.0 years; mean duration of hypertension: 10.9?8.5 years). All patients underwent ultrasonography of the heart and common carotid artery. Results. Group 2 patients showed a significant decrease in maximal transmitral flow velocity during early diastolic filling (0.61?0.12 m/s) and a decrease in maximal transmitral flow velocity during late diastolic filling (0.65?0.11 m/s) compared with Group 1 patients (0.66?0.09 m/s and 0.69?0.09 m/s, respectively,

Aim.  Atherosclerosis is one of the most important complications of type 2 diabetes mellitus (T2DM). In the present study, we aimed to assess the carotid intima-media thickness in type 2 diabetes patients with the arterial hypertension (AH) comorbidity. Materials and Methods.  96 patients with T2DM and AH (30M/66F, aged 53.4?5.4 years, duration of diabetes 7.7?7.5 years) and 30 hypertensive patients without diabetes (12M/18F, aged 53.1?6.0 years) were enrolled in this study. Stiffness indices for right and left common carotid arteries were assessed with noninvasive ultrasound method in both groups. Results. Difference in the intima-media thickness was statistically significant between diabetic and euglycemic patients (1.26?0.17 mm vs. 1.10?0.14 mm, respectively; p0.05), in contrast with their counterparts with longer experience of T2DM (1.27?0.17 mm vs. 1.10?0.14 mm;

Aim. Sulfonylureas (SU) are widely used in everyday clinical practice in treatment of patients with type 2 diabetes mellitus (T2DM). There is a considerable variability in SU effects, which may be caused by psychological, social, biological and genetic factors. The aim of the study was to investigate the association between rs5219 KCNJ11 gene and rs757110 ABCC8 gene polymorphism and long-term response to SU-drugs of second and third generation in the Novosibirsk region. Materials and Methods. 326 patients with type 2 diabetes in the Novosibirsk region were examined. Patients were divided into 2 groups, depending on HbA1c level. The first group included patients with target HbA1c levels on SU monotherapy. The second group included patients who did not reach target HbA1c levels on the highest dose of SU. Genotyping of KCNJ11 (rs5219) and ABCC8 (rs757110) was performed by TaqMan real-time PCR (ICBFM SB RAS, Novosibirsk, Russia). Results. Patients with type 2 diabetes with a good response to SU-therapy compared to the group of patients with a poor response to SU-therapy were older (65.8?9.1 years vs. 61.6?7.9 years,

Aim.  To investigate the association of polymorphisms in TCF7L2 and PPARG2 genes with type 2 diabetes mellitus (T2DM) in Novosibirsk population. Materials and Methods. We examined 391 patients with T2DM and 556 individuals with normal glucose metabolism. Allelic identification was performed with TaqMan technique, implementing allele-specific real-time PCR. Results.  Analysis shows that allelic frequency distribution of rs1801282 variant of PPARG2 gene and rs7903146 variant of TCF7L2 differs significantly between the study and control groups (OR [CI 95%]=1.44 [1.12?1.85], p=0.005 and OR [CI 95%]=1.57 [1.17?2.10], p=0.003, respectively). T2DM patients with T/T genotype of rs7903146 variant of TCF7L2 gene had lower BMI (p=0.02). Observed combination of risk alleles reached 99%. Combined beta-cell dysfunction and insulin resistance genotypes were identified in 56% of tested subjects, isolated insulin resistance ? in 42.2% of subjects, and isolated beta-cell dysfunction ? in 0.8% of subjects. Conclusion.  Our data shows that carrier state of 12Pro rs1801284 variant of PPARG2 gene and T-allele rs7903146 variant of TCF7L2 gene are associated with T2DM in Novosibirsk population, increasing its risk 1.44 and 1.57 times, respectively. Combination of these polymorphisms was observed in 99% of patients with T2DM
