Session Title: Miscellaneous Rheumatic and Inflammatory Diseases I

Session Type: ACR Concurrent Abstract Session

Session Time: 2:30PM-4:00PM

Background/Purpose: Familial Mediterranean fever (FMF) is the most common autoinflammatory disease and colchicine is the mainstay of treatment. Around 30-45% of FMF patients were reported to have attacks despite the colchicine treatment. Currently the data regarding the treatment of colchicine unresponsive or intolerant FMF patients is limited and the most promising alternatives seem to be anti-interleukin-1 (IL1) agents. Herein we report our experience in the off-label use of anti-IL1 agents in a large group of FMF patients.

Methods: This study was conducted by the means of Turkish Multi-centered Investigations Platform in Rheumatology (TULIP). Twenty-one centers from different geographical regions of Turkey were included in the study. Medical records of all FMF patients who used anti-IL1 treatment for at least 6 months were reviewed. Demographics, disease related clinical and laboratory data were collected by a web based structured questionnaire.

Results: In total 135 FMF patients (69 [51%] male, mean age 34.1 [range; 18-67] years) were included in the analysis. In our FMF patients the mean age at symptom onset was 12.3 (range; 1-45) and at diagnosis was 20.1 (3-60) years. 98 patients were carrying M694V mutation. The mean colchicine dose was 1.8 (1.0-4.0) mg/day and attack frequency was reported to be decreased from a mean of 26/years (3-96) to 13.9/years (0-96). 116 out of 135 patients were put on anakinra and 19 on canakinumab treatment due to colchicine resistance in 114 patients, amyloidosis in 15 and other reasons in 4 patients. During the median 14.5 (6-69) months of treatment period; yearly attack frequency was significantly reduced (P<0.001), and 74 (54%) patients reported no FMF attacks. Besides serum levels of C-reactive protein, erythrocyte sedimentation rate, and 24 hours urinary protein excretion were significantly reduced, as shown in table. Although serum creatinine levels were also improved with anti-IL1 treatment, it was not reached to statistical significance.

Conclusion:  The results of this large study showed that anti-IL1 treatment is an effective alternative for not only controlling the attacks but also decreasing the proteinuria in quite challenging FMF patients.
