[Complicated malaria tropica in an infant].
We report on a five month-old infant from Cameroon, who was admitted because of febrile gastroenteritis after living in Germany for two weeks. Since the patient was somnolent, had a parasitaemia of Plasmodium falciparum of 230,000/microliter, a haemoglobin concentration of 5.3 g/dl and a thrombocytopenia, a complicated falciparum malaria was diagnosed. Treatment was started immediately with intravenous 20 mg quinine/kg bw as a loading dose, followed by 10 mg/kg bw every 12 hours, combined with intravenous clindamycin 10 mg/kg bw bd. Red blood cells were transfused once. The parasitaemia dropped to 2000 trophozoites/microliter within 48 hours. No asexual stages were detectable from the third day of treatment on. Weekly controls for the following four weeks remained negative. The mortality rate of complicated malaria is 50% in the first year of life, which can be reduced by early treatment. We present this case to draw attention to therapeutic options in infants.
