Circulating ovarian autoantibodies and FSH and LH levels in adolescent girls with primary menstrual cycle disorders.
Seventy three adolescent patients with primary menstrual disturbances were studied by immunofluorescent methods for prevalence of ovarian autoantibodies (O-Ab), the enzyme immunoassay (EIA) method for examination of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) hormonal levels was used. Clinically healthy girls (40) served as controls. Patients were divided into a group of 13 girls with primary amenorrhea (PA) and a group of 60 girls with oligo and/or secondary amenorrhea (OSA). In the PA group 38.5% positivity linked to ooplasm (OO), zona pellucida (ZP), and membrana granulosa cells (MG), as well as 46.2% to theca folliculi interna (TI) and 53.8% to lutein cells (LC), was detected. Statistically significant differences (p < .05) of LH levels between OO immunopositive and negative girls (19.0 and 9.4 mU/ml) were found, while FSH values were not different. In the OSA group a 16.7% positivity linked to OO, 23.3% to ZP and MG, 38.3% to TI, and 58.3% to LC were detected. Significant linkage between MG immunopositive and negative girls and FSH:LH ratio values were estimated. FSH values were significantly different (p < .05) for PA and OSA groups (23.7 and 6.7 IU/l) which corresponded particularly with higher findings of Ab in germ line-cells (OO-, ZP-, and MG-Ab). A striking correlation between evidence of O-Ab and menstrual cycle irregularities was found. It could support a possible coincidence of autoimmune mechanism in these dysfunctions. Localization of O-Ab-binding was verified at the electron microscopic level.
