1 · What the graph read from it

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.

2 · The registry

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

backgroundGlobal emergence of rapidly developing resistance to multiple antifungal drugs and high mortality pose challenges to the treatment of invasive Candida auris infections. New therapeutic approaches are needed, such as repurposing drugs including combination with antifungals. Statins have been reported to exert antifungal effects against various Candida species.

objectivesOur study investigated potential synergy between the statins (rosuvastatin and fluvastatin) and azoles (voriconazole, posaconazole and isavuconazole) on clinical isolates of C. auris.

methodsTwenty-one clinical isolates of C. auris were obtained. Chequerboard assays based on the CLSI broth microdilution method were used to assess synergy based on FIC index (FICI) calculations of MICs of individual drugs and in combinations.

resultsSingle drug geometric mean (GM) MICs of fluvastatin and rosuvastatin were ≥128 mg/L in all 21 isolates. GM (range) MICs of posaconazole, voriconazole and isavuconazole were 0.259 (0.016-1 mg/L), 0.469 (0.016-2 mg/L) and 0.085 (0.004-1 mg/L), respectively. Combination of azoles with fluvastatin showed synergy in 70%-90% of C. auris isolates. In particular, voriconazole/fluvastatin resulted in 16-fold reduction in voriconazole MIC and synergy in 14/21 (67%) isolates. Posaconazole/fluvastatin resulted in 8-fold reduction in posaconazole MIC and synergy in 19/21 (90%) isolates.Combining rosuvastatin with the azoles also showed synergy against C. auris in 40%-60% of the isolates and additive effect in 40%-50%. None of the combinations was antagonistic.

conclusionsOur results provide a rationale for pursuing in vivo synergy tests as well as clinical studies to explore tolerability, treatment outcomes, optimal dose and exposure targets.
