What this trial studies

This cohort study aims to investigate the disease course and treatment response of patients with idiopathic retroperitoneal fibrosis (IRPF) across China. Patients diagnosed with definite or possible IRPF will be enrolled, and an online database will be established to collect clinical manifestations, demographic features, laboratory characteristics, immunological tests, imaging, and pathological features. The study will focus on understanding the complex clinical phenotype of IRPF and its association with other autoimmune conditions. The primary endpoint is to document the clinical manifestations of IRPF patients, while secondary endpoints will explore various characteristics and treatment outcomes.

Who should consider this trial

Good fit: Ideal candidates are males and females aged 18-75 diagnosed with definite or possible idiopathic retroperitoneal fibrosis.

Not a fit: Patients with malignancies, other autoimmune diseases, or secondary forms of retroperitoneal fibrosis will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding of IRPF and improve treatment strategies for affected patients.

How similar studies have performed: While there may be limited studies on IRPF, this cohort approach is novel in the context of a comprehensive registry in China.
