ABSTRACT
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 patient's clinical symptoms and radiologic lesions of vertebral sarcoid dramatically improved after treatment with infliximab.

Abciximab, a platelet glycoprotein IIb/IIIa receptor blocker, is a well-known agent in percutaneous coronary intervention because of its antiplatelet, antithrombotic effects, which allow for good outcome. Major bleeding is a well-recognized complication of abciximab therapy, and pulmonary hemorrhage, although infrequent, is a serious, under-recognized, and often fatal complication. We describe a case of fatal pulmonary hemorrhage in a young woman who presented with acute myocardial infarction and cardiogenic shock and was treated with abciximab in conjunction with percutaneous coronary intervention. The possibility of diffuse pulmonary hemorrhage should be strongly suspected in the presence of hypoxemia, infiltrates on chest radiography, and a decrease in hemoglobin. Awareness about this complication of abciximab therapy on the part of physicians and health care professionals is strongly warranted. Therapy that may be used if diagnosis is promptly made includes bronchoscopic-guided balloon tamponade or iced saline lavage. These therapeutic interventions are still in the developmental stage, and to date there are no trials to document their efficacy and survival benefit.
