Is this trial a fit for you?

Likely a good fit

Probably not a fit

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

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.

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 gone: 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.
