Abstract

Objective: This study investigates severe malaria in African adults living in a seasonal endemic area.

Design: A prospective study of all adults admitted with severe malaria over 2 consecutive seasons: October 1990 till January 1991 and October 1991 till January 1992.

Setting: ICU (15 beds) of Hôpital Principal, Dakar, Sénégal.

Patients: 23 patients: 14 men and 9 women with a mean age of 30 +/- 3 years were included in the study; all fulfilled the 1990 WHO criteria for severe malaria.

Results: At admission, 12 patients were comatose (Glasgow Coma Scale < 10), 7 had generalized convulsions. Parasitaemia was 135 +/- 52 x 10(9)/l. Biological indications of severity were as follows: hypophosphataemia < 0.8 mmol/l in 14 cases, serum creatine phosphokinase > 500 IU/l in 15 cases; and PaO2 < 70 mmHg in 5 cases. Serum TNF alpha levels, measured in 16 cases, were increased at 298.4 +/- 63.5 pg/ml, serum levels of IL-6 and IL-2SR were also elevated: 609.5 +/- 304.2 pg/ml and 297.6 +/- 35.6 pg/ml respectively. Circulating IgM and IgG antibodies were found in 14 out of 16 patients. Serum levels of TNF alpha, IL-6 and IL-2SR correlated positively with each other. TNF alpha and IL-2SR were also positively correlated to parasitaemia. Intravenous therapy with quinine at loading dose was favorable in 19 patients. Four patients died during the study, 3 from multiple organ failure.

Conclusions: This work demonstrated that severe malaria in a seasonal endemic area displays original clinical features with a high rate of either cerebral malaria or multiple organ failure.
