Introduction: Familial Mediterranean Fever (FMF) is the most common autoinflammatory disease that has mainly been treated with colchicine since 1972. A significant portion of patients do not respond to colchicine and require further treatment, mainly IL-1β antagonists such as anakinra, canakinumab and rilonacept as IL-1β has a crucial role in pathogenesis of FMF. This review summarizes the current approach to treating FMF and discovers the pharmacological and clinical utility of IL-1 blocking agents based on accumulated evidence with a focus on anakinra.
Areas covered: This review focuses on anakinra treatment in FMF. The data obtained from case reports, case series, retrospective studies and a Phase III trial are analyzed. Safety and efficacy profiles of anakinra are discussed.
Expert opinion: Anakinra is the cheapest anti-IL-1 agent used in the treatment of colchicine-resistant FMF. It is shown to be effective and safe when used in adjunct to colchicine however its short half-life and potential to cause injection site reactions limit its use.
