Abstract

OBJECTIVES:
Anakinra and canakinumab are the most commonly used agents in colchicine resistant/intolerant patients. In this study we investigated long-term efficacy and safety of anakinra and canakinumab.
METHODS:
In this retrospective study, we enrolled 101 adult patients with familial Mediterranean fever (FMF). Clinical and laboratory parameters before and after treatment with anakinra/canakinumab and the side effects observed during the treatment were recorded. All patients received anakinra initially and switched to canakinumab, in case of inadequate response/intolerance.
RESULTS:
The median (IQR) duration of treatment with anti-IL-1 agents was 35 (24-47.5) months. 101 patients were treated with anakinra and 27 patients with canakinumab. The autoinflammatory diseases activity and attacks decreased with both anakinra and canakinumab. Anakinra was effective in decreasing proteinuria and canakinumab was not effective in decreasing proteinuria in anakinra unresponsive patients. The modified FMF score was achieved in 76.2% of anakinra and 88.9% of canakinumab group. Injection site reactions (ISRs, n:15) was the most common reason of discontinuation of anakinra and most of ISRs developed in first 3 months of treatment. One severe skin rash, two anaphylactic reactions and one severe neutropenia were observed with anakinra; in the first, eighth, twelfth and fiftieth months, respectively. No severe side effects or side effect-related discontinuation of canakinumab were observed.
CONCLUSIONS:
Anakinra and canakinumab seem to be effective in long-term management of FMF patients. Canakinumab had a favourable safety/tolerability profile. Anakinra is also generally safe, but the serious side effects that may be observed in the short and long-term use should be taken into account.
