Refractory vertebral sarcoidosis responding to infliximab

Treatment of refractory sarcoidosis may be challenging for clinicians. Despite treatment with conventional therapy, sarcoidosis may be progressive and debilitating. Previous studies have implicated a role for tumor necrosis factor-alpha in granuloma formation as seen in sarcoidosis. Tumor necrosis factor-alpha inhibitors are currently approved to treat rheumatoid arthritis. Crohn disease, psoriasis, psoriatic arthritis, ankylosing spondylitis, and juvenile rheumatoid arthritis. There have been recent case-reports supporting treatment of refractory and multisystem sarcoidosis with such agents. We report a case of sarcoidosis, involving the lung and vertebrae, which was refractory to conventional therapy. Our patients clinical symptoms and radiologic lesions of vertebral sarcoid dramatically improved after treatment with infliximab.
