Abstract

Objective: To investigate the level of cytokines and immune cells in the peripheral blood (PB) and peritoneal fluid (PF) of different stages of endometriosis.

Methods: A prospective study was conducted to include 97 women with (n 60) and without (n 37) histopathologically confirmed endometriosis. Based on rASRM classification, stage I/II and stage III/IV were categorized as early-and late-staged endometriosis. Prior to surgery, 10 ml of blood was withdrawn from antecubital vein and serum was obtained. Aliquots were made and stored at -70 degrees C until assayed for cytokines. PF was aspirated from the pouch of Douglas. Peripheral and PF samples were analyzed by ELISA in terms of IL-2, IL-4, IL-10 and IFN-gamma. Determinations of T helper, T suppressor, NK, and B cells were assessed by using cluster determinant-3 (CD-3), CD4, CD8, CD25, CD28, CD45, CD16, CD23 and antibodies against early T cell activation antigens such as CD45RA/CD45RO, CD-69 and late activation antigens such as HLA-DR. A multiparameter flow cytometry was applied to detect the cell activation antigen expression.

Results: In terms of cytokine levels in PB and PF's of control group and early- and late-staged endometriosis cases, no significant difference was depicted in the cytokine levels (p > 0.05). Levels of immune cells did not differ between three groups (p > 0.05).

Conclusions: The result of this study did not show any significant difference in PB and PF cytokine and lymphocyte subgroups between normal and early- and late-staged endometriosis.
