Association of Polymorphic Variants of TCF7L2 and PPARG Genes with Metabolic Markers in Patients with Early Disorders of Carbohydrate Metabolism.

We performed complex analysis of the association of polymorphic variants rs7903146 of the TCF7L2 gene and rs1801282 of the PPARG gene with metabolic parameters, insulin resistance, and ß-cell function in a group of patients with early signs of carbohydrate metabolism disturbances in a sample of Tyumen citizens. The study group consisted of 64 people (39 women, 25 men) aged 40-70 years. The distribution of frequencies of alleles and genotypes of the polymorphic markers rs7903146 and rs1801282 was analyzed and associations of carriage of major homozygous polymorphisms with various phenotypic traits were identified. Genotyping for polymorphic variants of TCF7L2 and PPARG genes was performed using allele-specific PCR with primers provided by Synthol company. Carriers of homozygotes for allele C of the polymorphic marker rs7903146 significantly differed from other respondents by a higher level of C-peptide, as well as by the presence of associations with waist circumference, elevated level of glycated hemoglobin, and arterial hypertension. Carriers of homozygotes for the allele C of the rs1801282 polymorphism of the PPARG gene differed from the group of carriers of homozygotes for the allele G and the group of heterozygote carriers by higher levels of triglycerides, as well as the presence of associations with waist circumference and the level of glycated hemoglobin.

[The role of a nutritional factor in the development of obstetric and perinatal pathology in obese women].

The review presents the literature data on the effect of the nutrition of women on the course of pregnancy and the condition of a fetus. The mother's body during pregnancy is the only source of nutrients for a developing fetus. The woman's nutrition before and during pregnancy affects not only her own health and the development of a fetus, but can also results in the risk of non-infectious diseases and obesity among their children throughout their lives. The data on the effect of poor nutrition of a woman in a pregravidal period on pregnancy and the health of a future child have been presented. This is especially important for pregnant women with obesity because metabolic disorders they have are aggravated by poor nutrition. It has been shown that the lack or excess of nutrients in the presence of maternal obesity contributes to the development of gestational complications and programs the development of metabolic disorders in children.

[Proinflammatory cytokine levels depending on the stage of hepatic fibrosis in patients with metabolic syndrome and non-alcoholic fatty liver disease].

AIM: To study levels of systemic inflammation markers and plasminogen activator inhibitor-1 (PAL-1) in patients with metabolic syndrome (MS) and establish their relationship with the progress of selected stages of non-alcoholic fatty liver disease (NAFLD). MATERIALS AND METHODS: 129 patients aged 18-59 yr with abdominal obesity and MS underwent elastometry for the assessment of the degree of fibrosis depending on concomitant metabolic disorders and measurement of proinflammatory cytokine levels. RESULTS: Disorders of carbohydrate metabolism in MS patients are associated with the high levels of systemic inflammation markers (CRP, TNF-α, IL-6) and a two-fold rise in the PAI-1 level. The progress of fibrosis is associated with the increase of cytokine levels. CONCLUSION: Patients with MS and NAFLD associated with disorders of carbohydrate metabolism need to be examined by elastometry for the detection of fibrosis with simultaneous measurement of IL-6 and PAI-1 levels as cardiovascular risk factors.

[A course of acute respiratory virus infections in patients with metabolic syndrome].

AIM: To determine specific features of a course of acute respiratory viral infections (ARVI) and changes in immunological status in patients with metabolic syndrome (MS). MATERIAL AND METHODS: Body mass index (BMI), waist circumference, levels of cholesterol, lipoproteins, triglycerides, cytokines and immunoglobulins were measured and glucose tolerance test was made in 120 patients with MS. Registration of ARVI during a year was verified by the presence of antigens in immunofluorescence reaction. RESULTS: MS patients have obesity of an abdominal type and immunoresistance. Concentration of proinflammatory cytokines and leukocyte count in blood increased proportionally to an increase in fat tissue mass, immunoglobulins content went down. ARVI in most evident MS were characterized by a sluggish and areactive onset, longer course, more frequent respiratory and cardiovascular complications. CONCLUSION: MS is a factor of risk of a sluggish and complicated course of ARVI.
