The aim of this retrospective study is to evaluate the efficacy of a single-dose anakinra during familial Mediterranean fever (FMF) attacks and its effect on the duration, severity, and frequency of attacks. The patients with FMF who had disease episode and received a single-dose anakinra during disease episode between December 2020 and May 2022 were included. Demographic characteristics, MEFV gene variants detected, concomitant medical conditions, demographics of recent and previous episodes, laboratory findings and length of hospital stay were recorded. A retrospective analysis of medical records revealed 79 attacks from 68 patients who met inclusion criteria. The patients had a median age of 13 (2.5-25) years. All patients reported that the average duration of their previous episodes lasted longer than 24 h. When the recovery time of attacks after subcutaneous anakinra application at the disease attack was examined, it was observed that 4 attacks (5.1%) ended in 10 min; 10 attacks (12.7%) in 10-30 min; 29 attacks (36.7%) in 30-60 min; 28 attacks (35.4%) in 1-4 h; 4 attacks (5.1%) in 24 h; and 4 attacks (5.1%) ended in more than 24 h. There was no patient who did not recover from their attack after a single dose of anakinra. Although the efficacy of a single-dose anakinra administration during FMF attacks in children needs to be confirmed by prospective studies, our results suggest that use of a single-dose anakinra during FMF attacks is effective in reduction of severity and duration of disease attacks.
