Abstract

Abstract : Background: Only few case reports and case series have analysed the efficacy of IL-1 inhibitors in the treatment of calcium pyrophosphate deposition disease (CPPD), reporting conflicting results. Objectives: The main aim of this systematic literature review (SLR) was to summarize the evidence in the use of biological therapies in CPPD. Methods: PRISMA-IPD guidelines were used for this review. Published articles reporting the use of TNFα and/or IL-1 inhibitors in the treatment of CPPD were reviewed. We performed a SLR using PubMed, Embase and Cochrane databases. The search resulted in 83 articles; 11 were further evaluated in the SLR. Results: Seventy-six patients were included: 2 received infliximab, whereas 74 anakinra. The main data of included studies are reported in table 1 . Sixty-seven (88.2%) patients presented with an acute CPPD (mean disease duration: 2.7±6.9 months; polyarticular involvement in 61.2%, oligoarticular in 31.3% and monoarticular in 7.5%), whereas 9 (11.8%) patients with a chronic CPPD (mean disease duration: 130.1±133.6 months; polyarticular involvement in 66.7% and oligoarticular in 33.3%). Anakinra was used in refractory disease (85.1%) or in patients with contraindications to standard treatments such as colchicine, oral glucocorticoids and/or non-steroidal anti-inflammatory drugs (23.0%). Clinical response to anakinra was reported in table 2 . Duration of anakinra treatment prior to complete resolution of symptoms was associated with the clinical phenotype of chronic CPPD (Rpb: 0.67, p<0.01) and with disease duration (R: 0.49, p<0.01). In 47 out of 57 (82.5%) responders, complete resolution of symptoms was observed within 4 days after the first injection of anakinra. Adverse events were reported in 4.1% of the cases: local skin reaction at the injection site, skin rash on the back and bacterial pneumonia. Conclusion: This SLR provides evidence in favour of the use of anakinra as a therapeutic option in patients with CPPD, especially in acute refractory CPPD or when standard treatments are contraindicated.
