[ON THE ISSUE OF AUTOIMMUNE OVARY DAMAGE DURING PUBERTY]

The aim of the study was to ascertain the influence of AІТ on the formation of autoimmune damage to ovaries by determining the connections between the levels of AOAB, ATPO, gonadotropic and sex hormone levels, and the functional state of the ovaries and thyroid gland. 198 girls age 10-18 were studied: 166 with AIT (AIT+ Group), и 32- without AIT (the AIT- Group). A defined difference between TTH. and ATPO, was revealed, which is explained by the presence of thyroid pathology in the AIT+ Group. Prolactin levels and ovarian volume were notably higher, while Progesterone levels were lower in the AIT+ Group. No discernable differences among levels of AOAB, sex hormones, Estrogen, Testosterone or antral follicules were observed. A direct correlation was revealed between AOAB levels and the girls' age both in the AIT+ and AIT- groups. AOAB data was divided into three tertials in order to study links with various hormonal homeostasis. Analysis of data obtained showed numerous correlative links between ATPO, AOAB, gonadotropins, sex hormones, TTH and ovarian volume in all tertials of both the AIT+ and AIT- groups; correlative links were found, too, between AOAB and ATPO in the III tertial groups AIT+ and AIT-. In adolescents with AIT disbalance occurs at all levels of hormonal homeostasis as well as in ovarian structure. Such changes and the presence of ATPO and AOAB may be associated with emerging autoimmune ovary damage.
