Hyperimmunoglobulin D and periodic fever syndrome (HIDS) is a rare, autoinflammatory condition caused by mutations in the mevalonate kinase gene. There is no standard treatment for HIDS, and randomized controlled trials are lacking. ⋯ Interleukin 6 blockade in HIDS has not been described. We report the case of a 13-year-old girl with HIDS, who failed to respond to colchicine, corticosteroids, etanercept, and anakinra but was successfully treated with the anti-IL-6 monoclonal antibody, tocilizumab.
