Abstract
Nocardiosis is an opportunistic infection caused by gram-positive, weakly acid-fast filamentous aerobic organisms. Three species cause infection in man: N. asteroides, N. brasiliensis, and N. caviae, the first one being the most common. With increased use of immunosuppressive therapy for various autoimmune diseases, opportunistic infection by Nocardia has increasingly been reported. N. asteroides infections manifest in various ways; the lungs, skin, and brain are the organs most frequently involved. We describe a patient with Evans' syndrome, a disease requiring long-term immunosuppression, who acquired systemic nocardiosis. The infection was primarily pulmonary, misdiagnosed as tuberculosis, with subsequent hematogenous dissemination to the skin and central nervous system. The diagnosis of cerebral involvement was difficult to prove, as the patient presented with stroke-like episodes. After a positive blood culture was obtained, antibiotic therapy was introduced. The patient's condition deteriorated and the brain with infiltration of the meninges, lungs, skin, and kidneys. Nocardia is an important but often overlooked opportunistic infectious agent in immunocompromised hosts, causing diagnostic and therapeutic problems. As the mortality of cerebral nocardiosis is greater than 80%, early diagnosis and appropriate therapy are crucial.
