Abstract

Objective: To determine whether there is a difference in fibrinolytic compounds in endometriotic tissue, endometrium, peritoneal fluid (PF), and plasma from women with endometriosis and in endometrium and PF from healthy women. Design: Prospective study. Setting: Two university clinics. Patient(s): Regularly menstruating women with and without endometriosis. Intervention(s): Tissue samples, PF, and blood were collected at surgery performed for clinical reasons. Main Outcome Measure(s): The antigen concentrations of plasminogen activators and plasminogen activator inhibitors (PAIs) in tissue homogenates, PF, and plasma were assayed by ELISA. Result(s): The concentrations of urokinase plasminogen activator (u-PA) and PAI-1 were higher in endometrium from women with endometriosis than in endometrium from controls and even higher in endometriotic tissue than in endometrium from both groups. In PF, the concentration of PAI-2 was higher in women with endometriosis than in controls. Conclusion(s): The high concentrations of u-PA and PAI-I in endometrium from women with endometriosis might facilitate implantation of endometrial cells and the high concentration in endometriotic tissue might contribute to their invasive growth. The inflammatory reaction may contribute to the high concentration of PAI-2.
