Background: Familial Mediterranean fever (FMF) is an autoinflammatory disorder associated with MEFV gene mutations. Recurrent febrile episodes associated with serosal inflammation, arthritis, and characteristic skin findings represent the classic presentation of FMF. Lifelong colchicine treatment is the standard of care. However, the feasibility of colchicine cessation in FMF remains controversial, with limited data, particularly in adults. Methods: FMF patients diagnosed between January 2005 and December 2021 were screened, and those who voluntarily discontinued colchicine without a clinical indication were identified. After applying exclusion criteria, eligible patients were divided into two groups based on the presence of attacks in the 6 months before discontinuation. Baseline characteristics and 1-year post-discontinuation outcomes were then compared between the groups. Results: Fifty-four FMF patients met the eligibility criteria: 17 attack-free for 6 months before colchicine discontinuation (Group 1) and 37 with attacks (Group 2). Group 1 patients were younger, started colchicine earlier, and had a milder phenotype with no M694V homozygosity. After discontinuation, Group 2 had higher attack rates, while CRP levels rose in both groups, more prominently in Group 1. Within 1 year, four patients (23.5%) in Group 1 and one (2.7%) in Group 2 remained attack-free with low CRP, and three patients in Group 2 restarted colchicine. Conclusions: Attack frequency during discontinuation can be anticipated from pre-discontinuation patterns; however, subclinical inflammation is less predictable. FMF patients with a milder phenotype without M694V homozygosity showed higher success rates of colchicine discontinuation in the first year. These findings suggest that colchicine discontinuation may be feasible in carefully selected patients under close monitoring. (Table presented.).
