Neurological Manifestations Do not Affect Cumulative Survival in Indian Patients with Antineutrophil Cytoplasmic Antibody Associated Vasculitis.

Abstract：

Background:Neurological manifestations are an important cause of morbidity in antineutrophil cytoplasmic antibody (ANCA) associated vasculitis (AAV). It is not clear whether or not they are indicative of a severe disease course with multiple organ involvement and shortened survival. Aims and Objectives:To characterize the neurological manifestations of AAV and analyze their relationship with other organ system and cumulative survival. Methods:This was a retrospective single-center cohort study of AAV patients at a tertiary care hospital in North India. Data was collected from medical records regarding clinical history, neurological examination, Birmingham Vasculitis Activity Score (BVAS), serology, electrophysiology, imaging, and histopathological examination findings of patients. Results:Ninety-two patients of systemic vasculitis were identified, 67 with granulomatosis with polyangiitis (GPA), 14 with microscopic polyangiitis, 8 with Churg-Strauss syndrome (CSS), and 3 with undifferentiated AAV. The median BVAS at presentation was 18.0 (interquartile range (IQR): 12.0). The median duration of follow-up was 31.3 months (IQR: 40.5). A total of 45.7% patients had neurological manifestations among which 23.8% presented with neurological complaints. Peripheral neuropathy was the most common manifestation noted in 23.9% of the patients. Among patients with GPA, 40.3% had neurological involvement (seen in 33.3% patients at presentation). Patients with nervous system disease were more likely to have associated musculoskeletal manifestations (P = 0.046) and less likely to have renal involvement (P = 0.017). The estimated cumulative survival of the subgroup with neurological involvement was 95.1 months from the time of diagnosis, which was not significantly different from the cohort without neurological involvement (113.8 months, P = 0.631). Conclusion:Neurological morbidity commonly accompanies systemic vasculitis. Nervous system disease does not affect the survival significantly in these patients.
