Abstract

Background and Purpose: Hydrogen sulphide is an important mediator of gastrointestinal mucosal defence. The use of non‐steroidal anti‐inflammatory drugs ( NSAIDs ) is significantly limited by their toxicity in the gastrointestinal tract. Particularly concerning is the lack of effective preventative or curative treatments for NSAID ‐induced intestinal damage and bleeding. We evaluated the ability of a hydrogen sulphide donor to protect against NSAID ‐induced enteropathy. Experimental Approach: Intestinal ulceration and bleeding were induced in Wistar rats by oral administration of naproxen. The effects of suppression of endogenous hydrogen sulphide synthesis or administration of a hydrogen sulphide donor (diallyl disulphide) on naproxen‐induced enteropathy was examined. Effects of diallyl disulphide on small intestinal inflammation and intestinal microbiota were also assessed. Bile collected after in vivo naproxen and diallyl disulphide administration was evaluated for cytotoxicity in vitro using cultured intestinal epithelial cells. Key Results: Suppression of endogenous hydrogen sulphide synthesis by β ‐cyano‐ L ‐alanine exacerbated naproxen‐induced enteropathy. Diallyl disulphide co‐administration dose‐dependently reduced the severity of naproxen‐induced small intestinal damage, inflammation and bleeding. Diallyl disulphide administration attenuated naproxen‐induced increases in the cytotoxicity of bile on cultured enterocytes, and prevented or reversed naproxen‐induced changes in the intestinal microbiota. Conclusions and Implications: Hydrogen sulphide protects against NSAID ‐enteropathy in rats, in part reducing the cytotoxicity of bile and preventing NSAID ‐induced dysbiosis.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • PPIs augmented the expression of bacteria with beta-glucuronidases activity, and this microbial imbalance could promote the spread of NSAIDs into enterohepatic circulation, increasing bile cytotoxicity and subsequently causing ulcerative lesions.

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.
