Abstract

Objective. To comparatively study the blood, peritoneal fluid (PF), and cystic contents (CC) levels of a number of cytokines (IL-6, IL-8, TNF-α), alpha2-macroglobulin (a2-MG), pregnancy-associated alpha2-glycoprotein (a2-PAG), lactoferrin (LF), and alphal-antitrypsin (a1-AT), as well as the concentrations of circulating immune complexes of class G antibodies with a2-MG and a2-PAG in Stage III external genital endometriosis to specify their role in the pathogenesis of the disease and the possibility of their use in differential diagnosis. Subjects and methods. A group of 48 women (33.2±1.8 years of age) diagnosed as having Stage III external genital endometriosis was examined. Sera from 35 apparently healthy women (38.20±2.06 years of age) selected according to the results of planned prophylactic medical examination and sera, PF, and CC from 10 women (41.9±6.5 years of age) with simple ovarian serous cysts (SOSC) were studied as control and comparison groups, respectively. The content of a2-MG, a2-PAG, and al-AT was measured by quantitative rocket immunoelectrophoresis. The levels of IL-6, TNF-a, IL-8, LF, a2-MG-IgG, and a2-PAG-IgG were examined using solid-phase enzyme immunoassay (EIA). Results. The patients with endometriosis were found to have higher levels of the immune complexes of a2-PA G-IgG, LF, al-AT, and TNF-a and a lower concentration of a2-MG than did the healthy individuals (only the a2-MG concentration was decreased in ovarian retention cyst (ORC). In endometriosis, PF showed higher a2-PAG-IgG and IL-6 levels and a lower LF concentration than in ORS. In this condition, CC exhibited increases in all the study indicators as compared with ORS. Conclusion. The found changes are indicative of the more magnitude of alterations in humoral immunity and more aggressive processes in endometriosis and may be used as additional diagnostic and prognostic criteria in the clinical practice of an obstetrician/gynecologist.
