Abstract

Objective To review data on the role of ethanol-induced alteration of Zn homeostasis in mediation of adverse effects of alcohol abuse.Methods The scholarly published articles on the association between Zn metabolism and alcohol-associated disorders (liver, brain, lung, gut dysfunction, and fetal alcohol syndrome) have been reviewed.Results It is demonstrated that alcohol-induced modulation of zinc transporters results in decreased Zn levels in lungs, liver, gut, and brain. Zn deficiency in the gut results in increased gut permeability, ultimately leading to endotoxemia and systemic inflammation. Similarly, Zn deficiency in lung epithelia and alveolar macrophages decreases lung barrier function resulting in respiratory distress syndrome. In turn, increased endotoxemia significantly contributes to proinflammatory state in alcoholic liver disease. Finally, impaired gut and liver functions may play a significant role in alcoholic brain damage, being associated with both increased proinflammatory signaling and accumulation of neurotoxic metabolites. It is also hypothesized that ethanol-induced Zn deficiency may interfere with neurotransmission. Similar changes may take place in the fetus as a result of impaired placental zinc transfer, maternal zinc deficiency, or maternal Zn sequestration, resulting in fetal alcoholic syndrome. Therefore, alcoholic Zn deficiency not only mediates the adverse effects of ethanol exposure, but also provides an additional link between different alcohol-induced disorders.Conclusions Generally, current findings suggest that assessment of Zn status could be used as a diagnostic marker of metabolic disturbances in alcohol abuse, whereas modulation of Zn metabolism may be a potential tool in the treatment of alcohol-associated disorders.

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.
