title: Purulent pericarditis in a patient with rheumatoid arthritis treated with etanercept and methotrexate.
abstract: Purulent pericarditis is rarely seen in this post-antibiotic era. We report a case of spontaneous purulent pericarditis in a patient with rheumatoid arthritis being treated with etanercept, a tumour necrosis factor-alpha (TNF-alpha) antagonist, and methotrexate, an immunosuppressant. Both are disease-modifying anti-rheumatic drugs. We discuss the pathophysiology of purulent pericarditis and the recent literature on the infectious complications of TNF-alpha antagonists.
