Familial Mediterranean fever (FMF) is the most common form of monogenic autoinflammatory conditions, and response to colchicine has been considered as one of its distinctive features among other hereditary periodic fever disorders. Prophylactic colchicine has been shown to be effective in the prevention of inflammatory attacks and development of amyloidosis. However, the highest tolerable doses of colchicine may not be adequate enough to manage these goals in approximately 5% of FMF patients. Inadequate response to colchicine in fully compliant FMF patients may be associated with genetic and/or environmental factors affecting disease severity and colchicine bioavailability. Clarification of the molecular pathogenic mechanisms of FMF has revealed that interleukin-1 beta (IL-1β) cytokine is the most likely target to attack, and several case reports and case series have already documented the efficacy and safety of available anti-IL-1 agents, such as anakinra, rilonacept, and canakinumab in those patients inadequately responding to colchicine. Characterization and early identification of those FMF patients with uncontrolled inflammatory activity have become more important after the availability of new treatment options for the prevention of disease-associated complications and permanent damages.
