Objective — to study the incidence and clinical and pathogenetic features of intestinal injury in patients with type 2 diabetes mellitus. Materials and methods. Examinations involved 138 patients with type 2 diabetes mellitus (DM 2), aged from 39 to 67 years (mean age 53 ± 5 years), including 82 women (59 %) and 56 men (41 %). In addition to general clinical methods, investigations included plasma levels of the transforming growth factor‑b1 (TGF‑b1) and vascular endothelial growth factor (VEGF), the hydrogen breath test with lactulose, endoscopic examination of the intestine with biopsy followed by staining with hematoxylin‑eosin, immunohistochemical determining of claudin‑1 and VEGF, and conduction of PAS‑reaction. Results. Diabetic enterocolopathy (DECP) was diagnosed in 72 (52.2 %) patients with DM 2. Clinical manifestations were nonspecific and similar to those of irritable bowel syndrome (IBS). It has been found that DECP correlates with the duration of the DM 2 course and was diagnosed more often in middle‑aged patients (52.1 ± 4.1 years). In patients with DECP, the increase in the proinflammatory cytokines TGF‑b1 and VEGF significantly exceeded those in IBS patients. Histologically the inflammatory cell infiltration in patients with DECP was more intense and diverse, there were signs of subatrophy of the glands with a relative decrease in the number of vacuoles in the goblet cells. The immunohistochemical study revealed that VEGF in the colon mucosa was visualized mainly in patients with DECP. Moreover, a tendency to a decrease in the claudin‑1 levels was established in these patients. Conclusions. Intestinal damage was revealed in 67.4 % of patients with type 2 diabetes mellitus, and DECP was diagnosed in more than half of patients. Diabetic enterocolopathy had nonspecific clinical symptoms, required differential diagnosis with IBS, and was not always accompanied with abdominal pain. The presence of DECP more often correlated with the bacterial overgrowth syndrome, and levels of proinflammatory cytokines in the blood plasma and intestinal mucosa of these patients was raised.

Several studies have demonstrated that chronic and low-grade inflammation is closely linked to type 2 diabetes mellitus. The associated mechanisms are related to synthesis and release of proinflammatory and anti-inflammatory cytokines, mainly by the adipose tissue. Moreover, there are evidences that cytokines and adhesion molecules are important for development of diabetic nephropathy. Among the cytokines associated with inflammatory responses in type 2 diabetes mellitus, the transforming growth factor-β (TGF-β) has been recognized as a central player in the diabetic nephropathy being involved in the development of glomerulosclerosis and interstitial fibrosis, as observed in the course of end-stage renal disease. Although TGF-β1 is classically an anti-inflammatory immune mediator it has been shown that in the presence of IL-6, which increases before the onset of T2D, TGF-β1 favors the differentiation of T helper 17 (Th17) cells that are activated in many pro-inflammatory conditions. Since TGF-β1 mRNA and consequently serum TGF-β1 levels are under genetic control, this review aims to discuss the relationship of TGF-β1 levels and polymorphisms in the development of nephropathy in type 2 diabetes mellitus.

Lv Remodeling

The aim of the study was to evaluate the effect of type 2 diabetes mellitus (T2DM) and obesity influence on the left ventricular (LV) remodeling peculiarities in hypertensive patients. Materials and methods. In total, 327 patients, aged 38–74 years, were comprehensively examined. The enrolled patients were divided into 4 groups in dependence of the presence of associated disease: the 1st group – n = 87 hypertensive patients with T2DM combined with obesity, the 2nd group – n = 71 hypertensive patient with T2DM and the 3rd group – n = 65 hypertensive patients with obesity; the comparison group consisted of 74 patients with essential hypertension (EH) but without obesity or diabetes. Echocardiography was performed according to the standard method of H. Feigenbaum to estimate the LV parameters. HbA1c was determined by turbidimetric method. Serum glucose levels were determined by ELISA. Results. When comparing the three patient groups with those who had only EH, the most significant influence was found in combined influence of T2DM and obesity on the development of unfavorable type of LV remodeling with values of χ2 = 29.371 and Pearson's contingency coefficient (C) ‒ 0.393 (P < 0.05). The presence of concomitant T2DM without obesity had a significant moderate relationship with the development of unfavorable LV geometry, χ2 = 11.029 and C ‒ 0.266 (P < 0.05), which indicates a much smaller impact on the process compared to the polymorbid effect of T2DM with obesity. Comparison of patients with a combination of EH and obesity with those who had only EH did not show a significant effect of concomitant obesity on the development of unfavorable types of LV geometry with values of χ2 and C: 0.529 and 0.062, respectively (P > 0.05). Conclusions. Essential hypertension with type 2 diabetes mellitus and obesity polymorbidity, but not in combination with type 2 diabetes mellitus or obesity alone, has the most significant association with hypertrophic types of LV remodeling. The co-existence of type 2 diabetes mellitus and obesity in hypertensive patients leads to the development of predominantly LV concentric hypertrophy.
