Evaluation of frequency and the attacks features of patients with colchicine resistance in FMF

Abstract

Introduction: Colchicine is the mainstay for the treatment of FMF, which is an auto-inflammatory disease mainly with relapsing polyserositis. Despite daily doses of 2 mg ormore each day, approximately 5% to 10% of the patients continue to suffer from its attacks. In this study, we aimed to investigate the depression and attack features in patients withFMF who have colchicine resistance (CR).Patients e Methods: CR was defined for FMF patients with 2 or more attacks within the last6 months period while using 2 mg/day colchicine. Eighteen patients (9 Female/9 Male) wereenrolled into the CR group and 41 patients were enrolled into the control group (12 Male/29Female). Demographic, clinical e laboratory findings, treatment adherence, and the BeckDepression Inventory (BDI) scores were evaluated. Results: The age of onset of FMF was significantly lower in the CR group (12.3 yrs vs. 16.9 yrs, P = 0.03). Disease duration was longer in the CR group (P = 0.01). Abdominal and leg pain dueto exercise were significantly more frequent in the CR group versus controls (83% vs. 51%;P = 0.02 e 88% vs. 60%; P = 0.04, respectively). Patients with BDI scores over 17 points weremore frequent in the CR group compared to controls (50% vs. 34.1%; P < 0.001).Discussion: We found that: (1) the age of disease onset was lower and (2) the disease durationwas longer in CR group. Pleuritic attacks, hematuria e proteinuria were more frequent in CRpatients. We propose that depression is an important factor to consider in the susceptibilityto CR. © 2014 Elsevier Editora Ltda.
