title: Failure of trimethoprim/sulfamethoxazole in invasive Nocardia asteroides infection.
abstract: A case of pulmonary nocardiosis occurred with progressive involvement of the pleura, pericardium, mediastinum, and sternum. Surgical resection and drainage procedures followed by administration of the drug combination, trimethoprim/sulfamethoxazole, over a six-month period led to clinical recovery. Discontinuation of drug therapy, however, was followed by relapse and further invasion by the same organism. A literature survey of Nocardia asteroides infections treated with trimethoprim/sulfamethoxazole disclosed that posttreatment follow-up is often too brief or unknown, making the ultimate success of therapy uncertain.
