What this trial studies

This is an international, multicenter, non-interventional registry that collects both retrospective and prospective longitudinal data on people with Takayasu arteritis. Participating centers upload routine demographic, clinical, laboratory, and imaging data plus details of diagnostic methods, management, and therapies. The project enables comparison of patient characteristics, treatment approaches, and prognoses across centers and regions. Data are gathered during usual clinical care and patients provide informed consent for inclusion.

Who should consider this trial

Good fit: People who meet the ACR 1990 or ACR/EULAR 2021 criteria for Takayasu arteritis and can give informed consent (or have a legal representative) are eligible, whether enrolled retrospectively or after diagnosis moving forward.

Not a fit: Patients who do not meet the formal diagnostic criteria or who cannot or will not provide informed consent are not eligible and are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, the registry could reveal patterns in disease course and treatment outcomes that help clinicians make better care decisions for people with Takayasu arteritis.

How similar studies have performed: Other vasculitis and Takayasu registries have provided useful natural history and outcome data, so this approach has precedent.
