RCT(Randomized Clinical Trial ) of Antibiotic Therapy in Chronic Endometritis

Summary

120 cases with a diagnosis of chronic endometritis, confirmed by the presence of plasma cells in endometrial biopsy sample identified by immunohistochemical staining using CD138 antibody, have been recruited. The subjects have been randomly divided into two groups, the experimental group have been given antibiotic (Levofloxacin and Tinidazole for 14 days) treatment, the control group did not receive any antibiotic. Initially it was planned for women in the control group to take placebo,but the organization was difficult, so it was changed prior to the start of the study to an open label study. A repeat endometrial biopsy sample have been obtained 2-4 weeks after completion of the antibiotic therapy to assess the response to treatment. The conversion rate will be compared between the two groups
