Acute synovitis induced by deposition of calcium pyrophosphate (CPP) and monosodium urate crystals involves interleukin-1β production and activation. The efficacy of blocking interleukin-1β activity (with an interleukin-1 receptor antagonist [anakinra] or interleukin-1β antibody) is well documented for gout attacks but
