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

Experimental evidence suggests that C inhibition and more particularly combined inhibition of C and the TLR coreceptor CD14 may be of therapeutic benefit in sepsis and other inflammatory conditions. A barrier to the testing and further development of many inhibitors is that their activity is species specific. Pig is a relevant species for experimental models of human disease, and this study undertakes a comprehensive comparison of the inhibitory efficacy of the C5 inhibitor Ornithodoros moubata C inhibitor (OmCI) in human and porcine whole blood ex vivo models of Escherichia coli-induced sepsis. The effect of OmCI on complement activity in pigs undergoing E. coli sepsis was also examined. Porcine and human serum, and whole blood anticoagulated with lepirudin, was incubated with E. coli and the effect of OmCI investigated. The ex vivo results were virtually identical in pig and human. OmCI completely ablated the activity of all three C pathways at 0.64 μM. E. coli-induced C activation and expression of CD11b (wCD11R3 in the pig), was abolished ex vivo at 0.32 μM OmCI. Combining anti-CD14 and OmCI reduced the formation of IL-8 and TNF-α more potently than the single inhibitors. OmCI also efficiently bound E. coli-induced leukotriene B(4) in pig and human plasma. In support of our ex vivo findings, in vivo the activity of all C pathways was inhibited at 0.6 mg OmCI/kg pig. In conclusion, OmCI efficiently inhibited pig and human C activation, has accompanying anti-inflammatory effects and is a promising candidate inhibitor for further in vivo studies of sepsis.
