POLYMORPHISM OF SOME GENES IN PATIENTS WITH CHRONIC ENDOMETRITIS

Abstract

Chronic inflammation of the endometrium is one of the causes of infertility and impaired menstrual function. The issues of the diagnosis and treatment of this disease are often discussed, but remains too unclear. In connection with this, the study of the role of genetic polymorphism in patients with chronic endometritis is topical. The occurrence of polymorphisms in promoter sites of VEGF, ApoE, ESR1, PPARGC1A, MMP9, eNOS genes in patients with chronic endometritis and in practically healthy women were studied. As primers, the DNA portion of the VEGF genes rs2010963 (G634C), ApoE rs429358 (Cys130Arg), ESR1 2228480 (Thr594Thr), PPARGC1A 8192678 (Gly482Ser), MMP9 17576 (Gln279Arg), and eNOS 1799983 (Glu298Asp) were used. To study the polymorphic variants of genes investigated, a real-time polymerase chain reaction was used, the material was sampled by smear extraction from the mucous membrane of the oropharynx. In the analysis, the percentage of homozygotes and heterozygotes, the prevalence of the normal and pathological (minor) allele were counted. Based on the results obtained, it can be assumed that in patients with chronic endometritis polymorphism of genes responsible for angiogenesis, oxidative processes in the body and metabolism is more common. In particular, there was noted a statistically significant predominance of polymorphism in the promoter sites of the eNOS and ESR1 genes in patients with chronic endometritis, which may be indicative of negative genetic associations with impaired fertility; at the same time, the issues of the presence of genetic polymorphism of the genes MMP9, VEGF and ApoE and a lower frequency of somatic and gynecological pathology in a group of practically healthy women require further study.
