Does the Use of Dihydroartemisinin-Piperaquine in Treating Patients with UncomplicatedfalciparumMalaria Reduce the Risk for Recurrent NewfalciparumInfection More Than Artemether-Lumefantrine?

[摘要] Malaria contributes significantly to the global disease burden. The World Health Organization recommended the use of artemisinin-based combination therapies (ACTs) for treatment of uncomplicatedfalciparummalaria a decade ago in response to problems of drug resistance. This review compared two of the ACTs—Dihydroartemisinin-Piperaquine (DP) and Artemether-Lumefantrine (AL) to provide evidence which one has the ability to offer superior posttreatment prophylaxis at 28 and 42 days posttreatment. Four databases (MEDLINE, EMBASE, Cochrane Database and Global Health) were searched on June 2, 2013 and a total of seven randomized controlled trials conducted in sub-Sahara Africa were included. Results involving 2, 340 participants indicates that reduction in risk for recurrent newfalciparuminfections (RNIs) was 79%at day 28 in favour of DP [RR, 0.21; 95% CI: 0.14 to 0.32,P<0.001], and at day 42 was 44% favouring DP [RR, 0.56; 95% CI: 0.34 to 0.90;P=0.02]. No significant difference was seen in treatment failure rates between the two drugs at days 28 and 42. It is concluded that use of DP offers superior posttreatment prophylaxis compared to AL in the study areas. Hence DP can help reduce malaria cases in such areas more than AL.
