[HIV-associated cerebral toxoplasmosis -- review and retrospective analysis of 36 patients]

Highly active antiretroviral therapy (HAART) has resulted in a reduction of morbidity and mortality in HIV-associated cerebral opportunistic infection. Before HAART, up to 50% of all HIV-infected patients in Europe developed cerebral toxoplasmosis, an encephalitis caused by reactivation of Toxoplasma gondii infection. Although potent therapeutical options exist, the prognosis is still poor. We describe the course of 36 AIDS patients with cerebral toxoplasmosis and present a review of clinical signs, diagnosis, therapy, and survival times. The main criteria for differential diagnosis from other secondary neuromanifestations such as primary CNS lymphoma, progressive multifocal leukencephalopathy, abscesses, and ischemic infarctions are described. Indications and problems of stereotactic biopsy are discussed.
