Treatment of UV depends on the severity of the disease and the occurrence of relapses. In patients refractory to colchicine or dapsone, glucocorticoids (GCs), conventional immunosuppressive agents or rituximab (RTX) can be used,1 2 leading to significant morbidity. Interleukin-1β (IL-1β) inhibitors are biologics mainly used in autoinflammatory diseases.3 We report here a French retrospective multicentr study of patients treated with IL-1β inhibitors for persistent disease despite GCs and/or immunosuppressive agents.
This French retrospective multicentre study was conducted in four departments of Dermatology and Internal Medicine. We included patients with persistent UV to at …
