The male\/female ratio was 0.49 in patients with arthritis. The frequency of at least one exon 10 mutation was high. The age of onset of symptoms was earlier for patients with arthritis. Monoarticular pattern was more frequent compared to oligo\u2010 and polyarticular patterns. Colchicine resistance was higher; the required colchicine dose for disease control and the frequency of use of biological agents were higher compared to general FMF population.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>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.<\/jats:p><\/jats:sec>","DOI":"10.1111\/imj.16495","type":"journal-article","created":{"date-parts":[[2024,8,22]],"date-time":"2024-08-22T02:19:01Z","timestamp":1724293141000},"page":"1802-1808","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Characteristics
