Background: Nonsystemic vasculitic neuropathy (NSVN) is a vasculitis syndrome clinically restricted to the peripheral nervous system. Although treatment may improve prognosis, daily activities of such patients after treatment have not been well studied. Methods: We evaluated clinical features, laboratory data, nerve conduction, and sural nerve biopsy findings for 16 unbiased consecutive patients with NSVN. Results: Initial symptoms included neuropathic pain (31%) and lower limb sensory disturbance (19%). The mean duration between disease onset and initial treatment was 4.1 ± 4.8 months. Mean modified Rankin scale scores were 3.13 at hospital admission and 2.69 at final follow-up. The poor outcome group had significantly decreased compound muscle action potentials of peroneal nerves and significantly more patients presenting with foot drop compared with the good outcome group. No other significant differences were found. Conclusion: Pretreatment foot drop signaled poor outcome in daily activities of patients with NSVN, and earlier treatment may be critical for these patients. © 2014 S.
