Oral clindamycin and pyrimethamine are an effective treatment for toxoplasmic encephalitis. Patients who have early neurologic deterioration despite treatment or who do not improve neurologically after 10 to 14 days of appropriate antitoxoplasma therapy should be considered candidates for brain biopsy.
A total of 30 patients (aged 6-56 years) with nocardiosis and infection due to human immunodeficiency virus type 1 (HIV-1) were identified in our institution between January 1985 and June 1989. Eighteen patients had an AIDS-defining illness before or concurrently with nocardiosis. The mean CD4 lymphocyte count was 109/mm3. Pulmonary nocardiosis in 21 patients, extra-pulmonary nocardiosis in 8, and pulmonary and extrapulmonary nocardiosis in 1 patient was diagnosed. Chest radiographs showed alveolar patterns of infiltrates in 14 patients, reticulonodular patterns in 2, mixed alveolar and reticulonodular patterns in 6, cavitation in 4, and pleural effusion in 3. Of 27 patients treated, the conditions of 22 improved, but the extensive disease in 5 progressed. For 14 patients, recurrence was rapid after their treatment was discontinued. Nocardiosis caused or contributed to the death of 19 patients; in six patients, there was no evidence of nocardial infection at death. Nocardiosis can be a fatal complication of advanced HIV-1 disease. Delayed diagnosis, extensive disease, and early discontinuation of treatment were associated with poor outcome.
Nosocomial transmission of M. tuberculosis from other HIV-infected patients with tuberculosis caused by multiple-drug-resistant bacilli can occur. These findings have serious public health implications and demand strict adherence to acid-fast bacilli isolation precautions.
We present clinical, bacteriologic, and pathological findings for four patients with AIDS and cutaneous miliary tuberculosis. All patients had generalized tuberculosis with hematogenous dissemination to multiple organs including the skin. Microscopic examination of the skin lesions revealed ill-formed or no granulomata, extensive necrosis, and numerous acid-fast bacilli. Mycobacterium tuberculosis was detected in the skin lesions by cultures for three patients and by polymerase chain reaction for one. Three of the isolates were resistant to at least isoniazid and rifampin, and one was susceptible to these drugs. The outcome was rapidly fatal for the three patients with multidrug-resistant tuberculosis. This report draws attention to the reappearance of a once-rare manifestation of disseminated tuberculosis which, in the setting of advanced human immunodeficiency virus disease, may offer the first indication of infection with multidrug-resistant M. tuberculosis and a poor prognosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
