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

Chronic alcohol abuse increases lung oxidative stress and susceptibility to respiratory infections by impairing alveolar macrophage (AM) function. NADPH oxidases (Nox) are major sources of reactive oxygen species in AMs. We hypothesized that treatment with the critical antioxidant glutathione (GSH) attenuates chronic alcohol-induced oxidative stress by downregulating Noxes and restores AM phagocytic function. Bronchoalveolar lavage (BAL) fluid and AMs were isolated from male C57BL/6J mice (8-10 wk) treated ± ethanol in drinking water (20% wt/vol, 12 wk) ± orally gavaged GSH in methylcellulose vehicle (300 mg x kg(-1) x day(-1), during week 12). MH-S cells, a mouse AM cell line, were treated ± ethanol (0.08%, 3 days) ± GSH (500 μM, 3 days or last 1 day of ethanol). BAL and AMs were also isolated from ethanol-fed and control mice ± inoculated airway Klebsiella pneumoniae (200 colony-forming units, 28 h) ± orally gavaged GSH (300 mg/kg, 24 h). GSH levels (HPLC), Nox mRNA (quantitative RT-PCR) and protein levels (Western blot and immunostaining), oxidative stress (2',7'-dichlorofluorescein-diacetate and Amplex Red), and phagocytosis (Staphylococcus aureus internalization) were measured. Chronic alcohol decreased GSH levels, increased Nox expression and activity, enhanced oxidative stress, impaired phagocytic function in AMs in vivo and in vitro, and exacerbated K. pneumonia-induced oxidative stress. Although how oral GSH restored GSH pools in ethanol-fed mice is unknown, oral GSH treatments abrogated the detrimental effects of chronic alcohol exposure and improved AM function. These studies provide GSH as a novel therapeutic approach for attenuating alcohol-induced derangements in AM Nox expression, oxidative stress, dysfunction, and risk for pneumonia.
