Understanding the natural history and outcomes of systemic vasculitis

Studies of the Natural History, Pathogenesis, and Outcome of Idiopathic Systemic Vasculitis

Observational National Institutes of Health Clinical Center (CC) · NCT02257866

This study is trying to understand how systemic vasculitis affects people over time and what signs can help predict how the disease will progress, involving both patients with vasculitis and healthy volunteers.

What this trial studies

This observational study aims to investigate the natural history, pathogenesis, and outcomes of idiopathic systemic vasculitis, which includes conditions like Takayasu's arteritis and Giant Cell arteritis. Participants, including those diagnosed with vasculitis and healthy volunteers, will undergo evaluations by specialized doctors, provide blood and urine samples, and may have imaging tests or biopsies performed. The goal is to identify genetic markers, symptoms, and imaging findings that can help predict disease progression and outcomes over time.

Who should consider this trial

Good fit: Ideal candidates include individuals aged 3 and older with a diagnosis of vasculitis or those suspected of having it, as well as healthy volunteers.

Not a fit: Patients under 3 years of age or those with active malignancies or infections may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and management of systemic vasculitis, potentially enhancing patient outcomes.

How similar studies have performed: While there have been studies on specific types of vasculitis, this comprehensive approach to understanding the natural history of multiple forms of idiopathic vasculitis is relatively novel.
