Popis: BACKGROUND: Obesity and androgen deficiency (AnD) are characterized by similar disturbances in metabolic parameters, the presence of signs of insulin resistance, metabolic syndrome, the risk of developing cardiovascular diseases (CVD) and vascular complications. These facts indicate the possibility of the presence of common mechanisms that determine the predisposition to the development of obesity and AnD, which may include genetic factors, in particular, the rs4646994 polymorphism of the ACE gene, which, according to recent data, is associated with the risk of developing CVD, hypertension, and obesity.AIM: To study the association of the carriage of polymorphic variants of the rs4646994 locus of the ACE gene with the features of anthropometric and androgenic status in men.MATERIALS AND METHODS: In the period from April 2020 to October 2021 there were observed male patients aged 18–75 years old, who were hospitalized in a therapeutic hospital because of comorbid somatic pathology (hypertension, coronary heart disease, dorsopathy, vegetative-vascular dystonia, gastroesophageal reflux disease, and others). Anthropometry, a study of the content of hormones of the reproductive system in the blood serum using enzyme-linked immunosorbent assay (ELISA), as well as a genetic study for the carriage of polymorphic variants of the rs4646994 locus of the ACE gene by the polymerase chain reaction (PCR) method, followed by electrophoresis of PCR products, were carried out. RESULTS: 82 patients took part in research. According to the results of genetic analysis, 17 people were assigned to the group of homozygotes for the wild type (I/I, G1), 41 people were assigned to the group of heterozygotes (I/D, G2), and 41 people were assigned to the group of homozygotes for the mutant allele (D/D, G3) 24 people. Body weight, chest circumference, waist and hips, body mass index in patients carrying the D allele of the rs4646994 polymorphism were statistically significantly higher than in I/I homozygotes. Differences in hormonal status also turned out to be statistically significant: patients from G1 compared with G2 and G3 had higher levels of total testosterone; from G1 compared to G3 — a higher level of free testosterone.CONCLUSION: An association of the carriage of the D allele of the rs4646994 polymorphic locus of the ACE gene with overweight and ADI was revealed.
