[Parasitemia in Plasmodium falciparum malarial attacks in children].

In order to evaluate the predictive value of parasitaemia, this parameter was measured on admission in 69 Gabonese children aged from 3 to 13 years hospitalized for Plasmodium falciparum malarial attacks. Fourteen of these children had cerebral malaria, 5 had isolated convulsions and 50 had uncomplicated attacks. The parasitaemia values measured were compared with those found in asymptomatic children of the same age range carrying trophozoites. There were no significant differences in mean parasitaemia count between the 3 types of malarial attack, and only the asymptomatic carriers had significantly lower counts. However, the wide scattering of individual values within each group indicated that simple measurement of parasitaemia is not discriminative enough to predict the course of malarial attacks in children living in endemic regions. In particular, malarial attacks with very low or very high parasitaemia value are possible, but similar values are found in asymptomatic carriers.
