Anakinra induces complete remission of nephrotic syndrome in a patient with familial mediterranean fever and amyloidosis

Abstract

Renal amyloidosis is one of the most severe complications of familial Mediterranean fever (FMF). Colchicine has reduced the incidence of this complication, which now only appears in untreated, under-treated and resistant patients, but it is usually ineffective in patients with advanced amyloidosis. Here we report a patient with FMF and biopsy-proven amyloidosis who presented with nephrotic syndrome despite colchicine treatment. Anakinra (an interleukin-1β inhibitor) was started and a dramatic complete remission of nephrotic syndrome was observed in the following months. Anakinra can be an effective treatment for FMF patients with severe secondary amyloidosis.
