Comparative efficacy of intramuscular artemether and intravenous quinine in Nigerian children with cerebral malaria

The efficacy of a 5-day treatment with intramuscular artemether (3.2-mg/kg loading dose followed by 1.6 mg/kg daily) was compared to that of the stand ard 7-day treatment with quinine (20-mg/kg loading dose followed by 10 mg/k g every 8 h) in a randomised clinical trial including 103 children aged 12- 60 months with cerebral malaria between 1994 and 1996. No statistical diffe rence of immediate efficacy was found between the two treatments. There wer e 11 (20%) deaths in the artemether group and 14 (28%) in the children who received quinine. The respective artemether versus quinine median fever cle arance times (h) were 39 (interquartile ranges [IQ] 30-54) vs. 48 (IQ 30-60 ), and parasite clearance 42 (IQ 24-60) vs. 36 (IQ 30-48). However, one pat ient who received artemether had a recrudescence on day 14, which was succe ssfully treated with sulphadoxine-pyrimethamine. Times to recovery from com a were 24 h (IQ 18-45) and 33 h (IQ 19-57), respectively. The occurrence of transient neurological sequelae including motor disabilities, cortical bli ndness, and afebrile seizures was also similar in the two groups. No advers e reactions to the two drugs were recorded during the study period. Artemet her represents an important option in the management of cerebral malaria in Nigeria especially in rural areas where facilities for intravenous adminis tration may not yet be optimal.
