Clinical and electrodiagnostic features of nerve conduction study-classified peripheral neuropathy in symptomatic patients with antineutrophil cytoplasmic antibody-associated vasculitis: a single-centre cohort study

Description

Ha and co-authors describe how often nerve damage shows up in ANCA-associated vasculitis, in this 2026 single-centre cohort study. In these diseases the immune system attacks small blood vessels. From 323 patients with the condition, they selected 97 for closer study. These patients had symptoms suggesting vasculitic peripheral neuropathy. Each received nerve conduction studies, electrical tests of nerve function, within three months of diagnosis.

The tests supported a neuropathy diagnosis in 55 patients, which is 56.7 percent of those examined, and a mixed pattern of nerve injury accounted for 83.6 percent of confirmed cases. The peroneal nerve in the leg was affected most often, in 70.9 percent of cases, and nerve biopsies taken from 12 patients agreed with the electrical findings in 75 percent of comparisons. The authors conclude the electrical tests add objective evidence when vasculitis-related nerve damage is suspected.
