Abstract

Plasmodium falciparum Pfcrt-76 and Pfmdr1-86 gene polymorphisms were determined during a clinical trial in Burkina Faso comparing the efficacies of dihydroartemisinin-piperaquine (DHA-PPQ) and artemether-lumefantrine (AL). Significant selection of Pfcrt-K76 was observed after exposure to AL and DHA-PPQ, as well as selection of Pfmdr1-N86 after AL but not DHA-PPQ treatment, suggesting reverse selection on the Pfcrt gene by PPQ. These results support the rational use of DHA-PPQ in settings where chloroquine (CQ) resistance is high.

摘要

在布基纳法索进行的一项临床试验中,比较了双氢青蒿素-哌喹(DHA-PPQ)和蒿甲醚-本芴醇(AL)的疗效,同时测定了恶性疟原虫Pfcrt-76和Pfmdr1-86基因多态性。在接受AL和DHA-PPQ治疗后,观察到Pfcrt-K76有显著选择,在接受AL治疗后但DHA-PPQ治疗后未观察到Pfmdr1-N86选择,这表明PPQ对Pfcrt基因有反向选择作用。这些结果支持在氯喹(CQ)耐药性高的地区合理使用DHA-PPQ。
