In vitro interaction of lumefantrine and piperaquine by atorvastatin against Plasmodium falciparum.
Article in Malaria journal, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThere is an urgent need for the discovery of new anti-malarial drugs and combination therapy. A combinatorial approach protects each drug from the development of resistance and reduces generally the overall transmission rate of malaria. Statins, the inhibitors of 3-hydroxy-3-methylglutaryl-Coenzyme A reductase and a family of lipid-lowering drugs, have in vitro anti-malarial properties, and more specially atorvastatin. However, atorvastatin has a short elimination half-life (14 hours) and an efficient combination of anti-malarial drugs must associate a drug with a short elimination half-life and a drug with a long elimination half-life. The objective of the present work was to identify new potential partners among standard new anti-malarial drugs with long elimination half-life, such as lumefantrine, piperaquine, pyronaridine and atovaquone, to improve the in vitro activity of atorvastatin against different Plasmodium falciparum strains to treat uncomplicated malaria.
methodsIn vitro interaction of atorvastatin in combination with lumefantrine, piperaquine, pyronaridine and atovaquone was assessed against 13 P. falciparum strains by isotopic test.
resultsAtorvastatin showed additive effects with pyronaridine, piperaquine and lumefantrine. Atorvastatin increased the in vitro activity of lumefantrine and piperaquine at concentrations expected in clinical observations. The average IC50 values of lumefantrine decreased significantly from 31.9 nM to 20.5 nM (a decrease of 35.7%) in combination with 1 μM of atorvastatin.
conclusionsEven though in vitro data indicate that atorvastatin improved the activity of lumefantrine and piperaquine, the same may not necessarily be true in vivo. Piperaquine, a new drug with long terminal elimination half-life, is currently a very promising anti-malarial drug.
