Treatment of hereditary autoinflammatory diseases

Abstract

The purpose of this review is to summarize recent advances in the treatment of the hereditary autoinflammatory diseases, focusing on Familial Mediterranean fever (FMF), tumor necrosis factor receptor-associated periodic syndrome (TRAPS), cryopyrin-associated periodic syndromes (CAPS) and mevalonate kinase deficiency (MKD). We discuss recently published studies and their implications for current patient care and future clinical research. Interleukin (IL)-1 blockade is effective in most autoinflammatory conditions. Younger patients require a higher dose per kg of body weight. In FMF, colchicine remains the treatment of choice. Single daily dosing appears adequate. When colchicine fails, IL-1 blockade is effective. In CAPS, the beneficial effect of IL-1 blockade is sustained, and side-effects are limited. There is no evidence that one IL-1 blocker is superior to the other. In TRAPS and MKD, IL-1 blockade appears effective. Some patients have sufficient suppression of inflammatory symptoms with NSAIDs or corticosteroids. Apart from CAPS and FMF, therapy of autoinflammatory diseases is based on small and retrospective studies. IL-1 blockade appears effective, but larger prospective trials are needed, especially in MKD, TRAPS and colchicine-resistant FMF patients.
