The mortality (death) rate is estimated to be greater than 50 percent. Pyrimethamine is a drug that appears promising for the primary prevention of cerebral toxoplasmosis in HIV-infected patients.\n\nAMENDED: 04-04-91 On the first day of therapy, a loading dose is given. After the first day, patients take pyrimethamine or placebo 3 times a week. Patients also take leucovorin calcium orally three times weekly. Enrollment occurs over approximately 12 months. All patients are followed on study until a common study close-out date and final analysis of the study. It is anticipated that this common close-out will occur when the mean duration of time on study therapy will be 3 years (approximately in January, 1994).\n\nORIGINAL design: On the first day of treatment, patients receive a loading dose of pyrimethamine or placebo, plus of leucovorin calcium. After the first day, patients take pyrimethamine or placebo three times a week. Patients also take folinic acid orally three times weekly.
