Abstract

Objective: To establish tissue inhibitor of metalloproteinase-I (TIMP- I) concentrations in peritoneal fluid (PF) and sera of women with endometriosis and compare them to disease-free controls. Design: Prospective randomized study. Setting: Academic medical center. Patient(s): Women with laparoscopically documented endometriosis and disease-free women of reproductive age, Intervention(s): Peritoneal fluid and sera were collected, and some women received gonadotropin-releasing hormone agonist (GnRH-a) therapy for endometriosis. Main Outcome Measure(s): Peritoneal fluid and sera TIMP-1 concentrations were measured with a specific RIA. Result(s): The TIMP- I concentrations were significantly lower in PF and sera of women with endometriosis compared with disease-free women. The GnRH-a therapy restored serum TIMP-1 concentrations. Conclusion(s): Aberrant expression and localization of TIMP- I may derange the proteolytic milieu of the peritoneal cavity and contribute to the etiology and underlying physiologic sequelae associated with endometriosis. Measurement of TIMP-1 in serum may aid in diagnosing endometriosis and assist with monitoring treatment efficacy in women with this disease.
