Corneal ulceration due to Nocardia asteroides.

A case of corneal ulceration due to infection with Nocardia asteroides is described. Microbiological examination of corneal scrapings permitted accurate diagnosis and suggested appropriate therapy. Nineteen other cases that have been described in the world literature are reviewed.

Disseminated nocardiosis in a patient with Cushing's syndrome.

Nocardia Asteroides infection may occur in corticosteroid treated patients. However, nocardiosis in the presence of endogenous Cushing's syndrome has been previously reported in rare cases. We report a patient with Cushing's syndrome from bilateral nodular adrenal hyperplasia, in whom a disseminated form of nocardiosis complicated his hypercortisolism.

Serological reactions to Nocardia antigens.

Sera from 23 patients with nocardiosis were tested for the presence of precipitating antibodies against an extract of Nocardia asteroides. Sera from nine of 20 patients infected with Nocardia asteroides and one of three sera from patients with Nocardia brasiliensis produced one to three precipitin lines with the antigen. Sera from eight of 55 patients with tuberculosis and 11 of 13 patients with leprosy also contained Nocardia precipitins. None of 33 sera from patients with cryptococcosis, blastomycosis, actinomycosis, histoplasmosis, coccidioidomycosis, mucormycosis or candidiasis contained Norcardia antibodies. None of the sera from ten patients infected with Staphylococcus aureus, ten patients infected with Pseudomonas, or 16 sera from uninfected patients contained Nocardia precipitins.

[Chest wall destruction: unusual presentation form of pulmonary nocardiosis].

Nocardia spp infection is associated with immunosuppresion states, neoplasms and immunosuppresors and glucocorticoids prolonged treatments. Pulmonary involvement is the most typic feature and the dissemination to chest wall and subcutaneous cellular tissue is uncommon. We report one case of pulmonary nocardiosis by Nocardia asteroides, in a diabetic patient without others risk factors, manifested as a chest wall abscess with fifth rib destruction. The treatment with cotrimoxazol after lesion drainage was successful. We review the literature and remain the different diagnostic and therapeutics attitudes.

Nocardia asteroides purulent pericarditis.

A case is reported of a 71-year-old woman who developed cardiac tamponade as a result of a pyopericardium. The causative organism was Nocardia asteroides. This is the first reported case in the United Kingdom and only the 9th to be reported in the world. Despite prior radiological and echocardiographic investigations, we were unprepared at surgery for the volume of pus encountered. The dense adhesions, adherent pericardium and loculations encountered emphasizes the need to explore such patients surgically. We would advocate vigilance as to the possibility of pericardial involvement, in any patient contracting Nocardia asteroides infection. The medical and surgical management of this case is discussed together with a review of the literature.

Disseminated nocardiosis as a complication of Evans' syndrome.

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.
