Non-cardiogenic pulmonary oedema induced by salazosulfapyridine.

A 25-year-old woman received oral salazosulfapyridine, 4 g/day, for treatment of ulcerative colitis. At 10 days later, she presented with fever and respiratory symptoms. Based on physical, laboratory and radiological findings, bacterial pneumonia and non-cardiogenic pulmonary oedema was suspected. Salazosulfapyridine was immediately halted and antibiotic therapy started. Two days later, her symptoms and abnormal findings had improved rapidly. Bacteriological studies were negative. Salazosulfapyridine-induced non-cardiogenic pulmonary oedema was diagnosed. Non-cardiogenic pulmonary oedema should be considered as one of several salazosulfapyridine- induced pulmonary diseases in patients who are receiving salazosulfapyridine and who develop respiratory symptoms and an abnormal CXR.
