Exploring the Role of Antibiotics in Women with Recurrent Miscarriage and Chronic Endometritis

The Prevalence of Chronic Endometritis and Therapeutic Benefits of Antibiotics in Women With Unexplained Recurrent Miscarriage

Observational Chinese University of Hong Kong · NCT06163092

This study is testing if antibiotics can help women with unexplained recurrent miscarriages who also have chronic endometritis by checking for infections and seeing how well the treatment works.

What this trial studies

This observational study aims to estimate the incidence of chronic endometritis (CE) in women experiencing unexplained recurrent miscarriage. Eligible participants will undergo endometrial sampling during their menstrual cycle to evaluate the presence of microorganisms associated with CE. The study will also investigate the therapeutic benefits of antibiotics, with treatment tailored based on the identified infectious agents or empirical protocols. Follow-up endometrial biopsies will assess the effectiveness of the antibiotic treatment.

Who should consider this trial

Good fit: Ideal candidates include women aged 20-45 with a history of two or more consecutive miscarriages before 24 weeks of gestation.

Not a fit: Patients with uncorrected uterine anomalies, active pelvic inflammatory disease, or those currently taking other antibiotics may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into effective treatments for women suffering from recurrent miscarriages linked to chronic endometritis.

How similar studies have performed: While the approach of using antibiotics for chronic endometritis in the context of recurrent miscarriage is relatively novel, similar studies have shown promising results in addressing endometrial infections.
