Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are male patients aged 18 years or older with a confirmed diagnosis of CAH due to 21-hydroxylase deficiency.

Probably not a fit

Patients with an uncertain diagnosis of CAH or those with CAH caused by other genetic mutations will not benefit from this study.

What this trial studies

This observational study aims to create a registry for male patients diagnosed with congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency. It will include both newly diagnosed patients and those with prior diagnoses from other centers, allowing for a comprehensive understanding of the disease. The study will involve retrospective and prospective data collection, including laboratory tests and imaging studies, all conducted according to standard clinical practices. The registry will serve as a reference for calculating the incidence and prevalence of CAH in the Emilia Romagna region.

Why it matters

Potential benefit: If successful, this registry could enhance the understanding and management of congenital adrenal hyperplasia in male patients.

How similar studies have gone: While this approach is observational and builds on existing knowledge, similar registries have been successful in enhancing disease understanding and patient care.
