Longitudinal Study for Central Nervous System Vasculitis

Vasculitis Clinical Trial

Official title: Longitudinal Study for Central Nervous System Vasculitis

Status Recruiting

Clinical Trial Summary

Primary central nervous system vasculitis (CNSV) is a potentially fatal, single-organ vasculitis that often involves a spectrum of neurologic complications, including strokes, cognitive and speech impairment, visual loss, dementia, and encephalopathy. The purpose of this study is to establish a research cohort to investigate the disease process, treatments, and patient outcomes in CNSV.

Clinical Trial Description

Primary central nervous system vasculitis (CNSV) is a potentially fatal, single-organ vasculitis that often involves a spectrum of neurologic complications, including strokes, cognitive and speech impairment, visual loss, dementia, and encephalopathy. Originally described in the early 1950s, research in the disease has been slow to progress, largely limited by the rarity of the disease and the lack of biologic materials for basic and translational investigations. To date, the bulk of research in the field has been clinical, largely consisting of retrospective case series, predominately from single sites, focusing on correlations among clinical, imaging, and histopathology data. Collectively these series suggest the existence of clinically-relevant subsets. Such studies, while enhancing our knowledge of this rare disease, are limited by small numbers of patients (especially those confirmed by histopathology), and the near absence of detailed investigations into the biomolecular and immunopathogenic basis of the disease.

Development of this longitudinal cohort and multicenter approach offers the potential to generate new insights, generate new questions, and further our understanding of its natural history, pathophysiology, genetic basis, and discovery of biomarkers to assess disease activity and prognosis.

Study visits will occur every 3 months for this first year, and then annually for two more years. Blood collection will occur at every visit. A physical exam and medical and medication history will at every visit; also, participants will be asked to complete several questionnaires to assess disease activity, health status, and tobacco, alcohol, and drug use. ;
