Characteristics of arthritis in patients with familial <scp>Mediterranean</scp> fever

Since M694V mutation is common and the colchicine dose required for disease control is high, we can conclude that the disease activity is high in FMF patients with arthritis. The frequency of sacroiliitis and spondyloarthropathy is significantly increased, especially in individuals with M694V mutation, suggesting that there may be a common pathway in their pathogenesis. FMF should be included in the differential diagnosis in patients presenting with arthritis in FMF endemic regions.
