Abstract
AIM: To determine the factors associated with colchicine resistance and the effect of colchicine resistance on health-related quality of life (QoL) in patients with familial Mediterranean fever (FMF). METHODS: Demographic and clinical features, MEFV gene mutations, and Pras disease severity scores were recorded. QoL was assessed using the Short Form-36 (SF-36) and FMF-QoL scales. Colchicine resistance was defined as at least 1 attack per month for 6 months at the maximum tolerated dose of colchicine in fully compliant patients. RESULTS: The mean age of 118 patients (90 female, 28 male) with FMF was 38.4 ± 12.5 years. The percentage of colchicine-resistant patients was 19.5%. In univariable analysis, smoking (odds ratio [OR] = 2.885; 95% confidence interval [CI] = 1.104-7.539; P = 0.031), attack duration (OR = 1.955; 95% CI = 1.137-3.360; P = 0.015), presence of arthritis (OR = 5.235; 95% CI = 1.508-18.179; P = 0.009), and disease severity score (OR = 1.790; 95% CI = 1.334-2.402; P < 0.001) were associated with colchicine resistance. The FMF-QoL and subscales of SF-36 except for role emotional and vitality, were different between colchicine-resistant and non-resistant patients (P < 0.05). CONCLUSION: Smoking, attack duration, presence of arthritis, and disease severity were associated with colchicine resistance in fully compliant FMF patients. Colchicine-resistant patients had poorer health-related QoL.
