Statin therapy and small fibre neuropathy: a serial electrophysiological study

Abstract

We describe three patients who developed small fibre neuropathy after 1 month of statin therapy with clinical resolution upon prompt drug withdrawal. All patients showed abnormal sympathetic skin responses (SSR) in comparison with controls. SSRs returned to normal in tandem with clinical improvement. One patient redeveloped small and large fibre neuropathy when the similar drug was readministered. The SSR is of value in the electrophysiological assessment and follow-up of statin-related small fibre neuropathy.
