Abstract

Significance: Evolution of malaria parasite drug resistance has thwarted efforts to control this deadly disease. Use of drug combinations has been proposed to slow that evolution. Artemisinin is a favorite drug in the global war on malaria and is frequently used in combination therapies. Here we show that using the whole plant ( Artemisia annua ) from which artemisinin is derived can overcome parasite resistance and is actually more resilient to evolution of parasite resistance; i.e., parasites take longer to evolve resistance, thus increasing the effective life span of the therapy.

  • Dry leaf consumption seems resilient against the evolution of artemisinin drug resistance as shown in humans and in Plasmodium yoelii-infected mice.

    “Another reason for increasing the in planta artemisinin content is that dry leaf consumption of A. annua is showing efficacy in human trials (Daddy et al. 2017; Munyangi et al. 2019) and seems resilient against the evolution of artemisinin drug resistance as maybe shown in humans (Daddy et al. 2017) and in Plasmodium yoelii -infected mice (Elfawal et al. 2015).”

    The Results and Discussion (page not available in our copy) report that dried whole-plant Artemisia annua was more resilient than pure artemisinin during experimental selection for resistance. But that evolution experiment used P. chabaudi-infected mice; the P. yoelii experiments tested treatment of an already artemisinin-resistant strain, not the evolution of resistance in that species.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
