Сervical Insufficiency and Genital Infection

Abstract

Despite the availability of diagnostics and modern methods of treatment, preterm birth with cervical insufficiency occurs in 44-57% of cases, while early preterm birth reaches 38,8%. To date, there is no doubt about the connection of premature labor and intraamnial inflammation, the frequency of which in cervical insufficiency reaches 80%. Most researchers are unanimous in the opinion that the ascending route of infection in intraamnial infection is a priority. It has been proven that a decrease in the absolute and relative amount of Lactobacillus spp., A change in the species composition of lactoflora or atypical vaginal colonization associated with premature birth and premature rupture of membranes. Conditionally pathogenic microorganisms of the vaginal biotope with an insufficient number of lactobacilli are capable of producing various proteases that destroy collagen, constituting the basis of connective tissue and determining the elasticity of the membranes, which allows us to consider cervicovaginal infections as one of the mechanisms of premature remodeling of the cervix and rupture of membranes. In that way, it is relevant to study the frequency and structure of genital infection in cervical insufficiency. The analysis of medical literature data, presented in the electronic libraries Elibrary and Pubmed for the last 10 years, devoted to the study of genital infection in cervical insufficiency. The issue of the relationship of cervicovaginal infections with premature remodeling of the cervix of the uterus was discussed, as well as studies on the role of intrauterine infection in the genesis of preterm labor. The results of scientific studies are presented, indicating both the direct influence of cervical incompetence on the risk of intraamnial infection and the root cause of genital infection in the pathogenesis of cervical insufficiency. Convincing data are given that timely diagnosis and treatment of violations of the vaginal biocenosis is one of the significant links in the prevention of premature birth. It is necessary to further study the pathogenetic relationship of cervicovaginal infections and cervical insufficiency.
