[Infliximab treatment for chronic sarcoidosis--a case series].

The management of chronic forms of sarcoidosis can be a difficult therapeutic problem. The purpose of this observational study was to analyze the effectiveness and tolerance of infliximab in chronic sarcoidosis. This multicentre retrospective study involved 31 cases of chronic, systemic, and/or pulmonary sarcoidosis treated by infliximab. Disease had been present for 9 years and involved a mean of four organs. Patients had received several immunosuppressive drugs and 30/31 were treated with corticosteroids (19 ± 16 mg prednisone/day) with the addition in 17 cases, of one or more other immunosuppressive agents. The duration of infliximab therapy was 13 ± 12 months. A beneficial response to infliximab was observed in 62% of the cases across all organs involved: 65% for lung involvement, 67% for skin lesions and 50% for central nervous system lesions. For other organs, responses were disparate. The corticosteroid sparing effect was small (2.8 ± 9.7 mg/day). Effectiveness was more frequent in patients who were treated with additional immunosuppressive agents. Thirteen (41.9%) patients developed side effects; in seven out of 13, side effects were severe, sometimes requiring infliximab to be stopped. Our study supports the continuing interest in the use of infliximab for the treatment of chronic sarcoidosis, but also highlights the frequency and severity of side effects. Indications are difficult to specify, and currently, its use should be restricted to clinical trials.
