This study found elevated IL-1beta and ICE levels but lower IL-18 levels in peritoneal fluid from women with endometriosis, indicating impaired IL-1 cytokine family secretion.

Abstract

PROBLEM: To assess whether interleukin (IL)-1beta, IL-18 and interleukin-1 converting enzyme (ICE) are involved in the pathogenesis of endometriosis. METHOD OF STUDY: Peritoneal fluid (PF) was obtained from 85 women with and without endometriosis. Peritoneal macrophages were cultured and the culture media collected. IL-1beta, IL-18 and ICE levels were measured by the enzyme-linked immunosorbent assay (ELISA). RESULTS: Levels of IL-1beta and ICE in PF of women with endometriosis were higher than those in the control group. However, PF level of IL-18 was significantly lower in the study group than in the controls. Higher secretion of IL-1beta by peritoneal macrophages and lower IL-18 and ICE in endometriosis patients than in control were observed. Following lipopolysaccharide (LPS) stimulation, the macrophages secreted more IL-1beta, IL-18 and ICE in all groups. CONCLUSIONS: The results pointed to impairment of the secretion of the IL-1 cytokine family in endometriosis. Invalid IL-1beta and IL-18 maturation by ICE may be an important pathogenic factor in endometriosis.
