Role of clindamycin in the treatment of acute toxoplasmosis of the central nervous system

Abstract

Cerebral toxoplasmosis related to AIDS was treated with a combination regimen of pyrimethamine, clindamycin, and spiramycin, and in a second trial with a combination of pyrimethamine and clindamycin. Both regimens proved to be equally effective. The experience with the second trial shows that spiramycin does not provide additional benefit. Myelosuppressive side-effects due to pyrimethamine were prevented in most cases by addition of folinic acid to the regimen at the start of the antitoxoplasmic therapy. These data suggest that the combination of pyrimethamine and clindamycin is an effective alternative to the commonly used regimen consisting of pyrimethamine and sulfonamides.
