RESUMO
Severe forms of malaria in children are responsible for 1 million deaths yearly in young children in hyperendemic areas. The main objective of this study was to identify and compare common manifestations of different forms of severe malaria and to evaluate the prognosis for hospital treatment in an endemic area. 271 files of children admitted into hospital between March 1991 and September 1996 were analysed. These children were confirmed to have Plasmodium falciparum in their peripheral blood. 78 patients (29%) had the severe form of malaria. 43 patients (53%) were under 5 years of age. The 5 severe types identified were characterized by very high temperatures 28 cases (36%), cerebral malaria 20 cases (26%), prostration and weakness 15 cases (19%), severe anaemia 14 cases (18%) and haemoglobinuria 1 case (1.3%). Cerebral malaria and severe anaemia were more common in children under 5 years old. The average parasitemia was 16,366 +/- 1390 parasites per microlitre. Clearance of parasitemia was obtained on day 3 in almost all cases; 6 patients with very high temperatures presented neither sign of visceral complications nor convulsions. The average period in coma for cases of cerebral malaria was 1.7 days; 12 anaemic patients were transfused. There were no deaths. No abnormality was found on physical examination after an average hospitalisation of 5.3 days. An early diagnosis and adequate treatment of severe forms of malaria in children by qualified personnel will usually result in a favourable prognosis in our area.
