Objective: To assess the prevalence of chronic endometritis in women with a history of recurrent early pregnancy loss (REPL) and/or fetal demise (FD).
Design: Observational cohort study using prospectively collected data.
Setting: Recurrent pregnancy loss program in an academic medical center.
Patient(s): Three hundred ninety-five women with a history of two or more pregnancy losses of less than 10 weeks' size or a fetal demise of 10 or more weeks' size.
Intervention(s): All women had an endometrial biopsy. Chronic endometritis was treated with antibiotics, and a second endometrial biopsy was recommended as a "test of cure."
Main outcome measure(s): Subsequent live-birth rate (LBR).
Result(s): The overall prevalence of chronic endometritis was 9% (35/395) in this cohort; 7% (21/285) in the REPL group, 14% (8/57) in the FD group, and 11% (6/53) in the combined REPL/FD group. The cure rate was 100% after a course(s) of antibiotics. The subsequent cumulative LBR was 88% (21/24) for the treated chronic endometritis group versus 74% (180/244) for the group without chronic endometritis. The per-pregnancy LBR for the treated chronic endometritis group was 7% (7/98) before treatment versus 56% (28/50) after treatment.
Conclusion(s): There was a high prevalence of chronic endometritis in this cohort. The test of cure was 100% with antibiotics. Subsequent LBRs after treatment were encouraging.
