RESUMO

Objective: The objective of this study was to analyze the relation and the predominance of the immune response patterns Th1 and Th2 in patients with endometriosis. Patients and Methods: Between February 2004 and April 2005, 98 patients were evaluated and divided into two groups, according to the presence (Group A) or absence of endometriosis (Group B), confirmed by histology. Peripheral blood and peritoneal fluid were collected from all patients to obtain the concentrations of interleukines (IL) 2, 4 and 10, tumor necrosis factor-alpha (TNF-alpha) and interferon-gamma (IFN-gamma) using flow cytometry. Besides the presence of endometriosis, we analyzed phase of menstrual cycle, clinical complaints, classification, site and histological differentiation of the disease. Results: We observed higher concentrations of IFN-gamma (median of 1.5pg/ml in Group A and 0.4pg/ml in Group B, p = 0.03) and IL-10 (median of 38.6pg/ml in Group A and 15.7pg/ml in Group B, p = 0.03) in peritoneal fluid of patients with endometriosis in relation to those without the disease. Patients with endometriosis presented a significant alteration in IL-4/IFN-gamma (p <0.001), IL-4/IL-2 (p = 0.006), IL-10/IFN-gamma (p <0.001) and IL-10/IL-2 (p<0.001) ratio concentrations of peritoneal fluid, with IL-4 and IL-10 predominance, reflecting a Th2 response predominance over the Th1. Conclusion: The results allow concluding that, in this study, it was observed a cytokine elevation related to Th2 immune response, indicating a predominance of this pattern of response in patients with endometriosis.
