Interleukin (IL)-1β blocking is effective for the treatment of gout flares and is recommended in patients with contraindications to the standard of care, such as stage 4-5 chronic kidney disease (CKD) patients. However, efficacy and safety data regarding these agents are lacking in this population. We aimed to investigate the efficacy and safety of anakinra for the treatment of gout flares in patients with stage 4-5 CKD or renal transplantation.
This retrospective study encompassing 3 academic centres included consecutive patients with stage 4-5 CKD or kidney transplantation who received anakinra for the treatment of acute gouty arthritis and completed at least one follow-up visit. Efficacy, occurrence of infection, and renal function variations were recorded.
Of the 31 included patients (24 men, mean age 72±11 years), 25 were non-transplant subjects with stage 4-5 CKD (mean estimated glomerular filtration rate, MDRD formula (eGFR) 22.7±6.5mL/min/1.73m
Anakinra may be a safe therapeutic option for gout patients with advanced CKD. Further randomized controlled studies are required to confirm our results.
