Understanding the progression of endometriosis and adenomyosis

ENDOCHAP Monocentric Cohort: Clinical and Molecular Study of Endometriosis and Adenomyosis

Observational Assistance Publique - Hôpitaux de Paris · NCT04481321

This study is trying to see if endometriosis and adenomyosis get worse over time by looking at symptoms and other factors to help improve diagnosis and treatment for those affected.

What this trial studies

This observational study aims to investigate whether endometriosis and adenomyosis are progressive diseases by examining symptoms such as pain, abnormal uterine bleeding, and infertility, as well as the size of anatomical lesions and recurrence rates. The study will also explore molecular aspects, including immune interactions between ectopic lesions and the normal endometrium, autoimmune responses, and the role of microbiota in these conditions. By identifying specific clinical and molecular markers, the research seeks to reduce the time taken for accurate diagnosis and management of these conditions.

Who should consider this trial

Good fit: Ideal candidates for this study are women aged 18 to 42 who are experiencing pelvic pain, infertility, or have a pelvic mass, and have a radiological diagnosis.

Not a fit: Patients who are HIV-positive, pregnant, have a cancer diagnosis, or refuse to sign consent will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved diagnostic methods and management strategies for women suffering from endometriosis and adenomyosis.

How similar studies have performed: Other studies have explored aspects of endometriosis and adenomyosis, but this specific approach focusing on disease progression and molecular markers is relatively novel.
