A 39 year old Asian with a recent renal transplant was diagnosed to have a mild cerebral falciparum malaria. IntroductionThe mortality of cerebral malaria in young children remains 10-40% (WARRELL et al., 1990) and attempts to reduce this figure must include the early and optimal use of quinine. It has the advantage of being able to be given intramuscularly once daily for only five days. Do not give quinine if a previous dose of quinine or mefloquine has been given in the previous 12 hours. Pentoxifylline (PTX) affects many processes that may contribute to the pathogenesis of severe malaria and it has been shown to reduce the duration of coma in children with cerebral malaria. Plasma quinine concentrations closely followed a bi-exponential decline. Despite optimal treatment, this condition kills 15% of those affected and leaves 30% of survivors with neurologic sequelae. Young African children with severe malaria are given quinine using a regimen designed for Thai adults. Cerebral malaria is the most severe and life threatening complication of Plasmodium falciparum malaria and carries a case fatality rate1 of 5-40%, with most deaths occurring within the first 24 hours.2 Although the recommended treatment of cerebral malaria is intravenous quinine,1 alternative drugs are necessary where intravenous treatment is not possible.3 Most studies … If available, patients should be managed in an intensive care unit or its local equivalent.
