Clindamycin therapy of cerebral toxoplasmosis in an AIDS patient.

A 47-year-old patient with AIDS and cerebral toxoplasmosis was treated with sulfadiazine pyrimethamine for 5 days. After developing a severe rash his regimen was changed to clindamycin 600 mg q 6 h intravenously and pyrimethamine 25 mg daily, given for 37 days. This resulted in improvement of clinical symptoms and complete resolution of CT scan abnormalities. Clindamycin combined with pyrimethamine may be a useful alternative therapy for cerebral toxoplasmosis in patients who can not tolerate sulfonamides.
