We examined 38 patients (mean age 55.92 ± 1.56 years) with a 3-5-year history of arterial hypertension. The study showed that hypertension is accompanied by endothelial dysfunction and one of its forming factors is activation of the inflammatory response. Highly sensitive diagnostic tests can verify initiation of inflammation in preclinical manifestations. The use of nonsteroidal anti-inflammatory drugs, irrespective of the tropism to cyclooxygenase forms, alleviates manifestations of endothelial dysfunction in patients with arterial hypertension.

The role of JAK/STAT3-mediated signaling pathway in the realization of the growth potential of mesenchymal precursor cells was examined in vitro. The stimulating role of JAKs and STAT3 towards proliferating activity of progenitor cells and their different role in the regulation of differentiation of the progenitor elements were demonstrated. Inhibitors of JAKs and STAT3 reduced the yield of fibroblast CFU and their mitotic activity. Blockade of JAKs accelerated and selective inactivation of STAT3 decelerated differentiation of progenitor cells.

The concept of metabolic syndrome as a cluster of risk factors for type 2 diabetes and cardiovascular diseases has undergone a number of evolutionary transformations over the past years. Incorporation of autonomic nervous system dysfunction into the pathogenesis of metabolic syndrome opens an opportunity for inclusion of a number of clinical entities in the cluster of metabolic syndrome as they mutually affect the course and clinical manifestations of pathologies involved in metabolic syndrome. To confirm this notion, a cross-sectional transverse study of a continuous sample of 158 patients with metabolic syndrome was performed. The study showed that, in the presence of metabolic syndrome, the incidence of cardiac autonomic neuropathy reaches 37.5%. A number of features of gastroesophageal reflux disease in patients with metabolic syndrome were found in the structure of complaints where regurgitation predominated. Fibrogastroduodenoscopy demonstrated endoscopically negative form of the disease in 38%, and, according to high DeMeester index by daily pH-metry, the alkaline reflux was present in patients in lying position over 25% of time. Young men with metabolic syndrome had high incidence of prostatic enlargement (increased prostate size and volume) as well as high incidence of the IPSS questionnaire  score corresponding to the initial manifestations of prostatic hyperplasia in the presence of insulin resistance and normal androgen levels. The study showed that dysfunction of the autonomic nervous system (along with insulin resistance) was the main converging point in the development of metabolic syndrome. This suggests that cardiac autonomic neuropathy, lower urinary tract symptoms, and gastroesophageal reflux disease may be included in the metabolic syndrome cluster.
