Treatment of sarcoidosis: grading the evidence.

Treatment of sarcoidosis recommendations are often based on clinical experience and expert opinion. However, there are an increasing number of studies which are providing evidence to support decisions regarding treatment. Areas covered: Several studies have identified factors associated with increased risk for organ failure or death ('danger'). There have been several studies focused on the role of treatment to improve quality of life for the patient. Sarcoidosis treatment often follows a progression, based on response. Corticosteroids remain the initial treatment of choice for most patients. Second-line therapy includes cytotoxic agents. Immunosuppressives such as methotrexate, azathioprine, leflunomide, and mycophenolate have all been reported as effective in sarcoidosis. Biologics and other agents are third-line therapy. The monoclonal antibodies directed against tumor necrosis factor have been shown to be particularly effective for advanced disease. Infliximab has been the most studied drug in this class. Newer treatments, including repository corticotropin injection and rituximab have been reported as effective in some cases. Expert commentary: In this review, we use the GRADE system to evaluate the currently available evidence and make recommendations regarding treatment.
