Influence of Age, Sex, and Helicobacter pylori Infection Before and After Eradication on Gastric Alcohol Dehydrogenase Activity.
Background: Gastric alcohol dehydrogenase may contribute to the metabolism of orally ingested ethanol and decrease the bioavailability of the drug. The aims of this study were to assess the impact of Helicobacter pylori infection and its eradication on gastric alcohol dehydrogenase activity and to r...

The aims of this study were to assess the impact of Helicobacter pylori infection and its eradication on gastric alcohol dehydrogenase activity and to relate the findings to gastric histology. Furthermore, the role of age- and sex-related differences in gastric alcohol dehydrogenase activity were studied. Methods: A total of 76 subjects (39 women and 37 men) underwent upper gastrointestinal endoscopy, and biopsies were obtained from the corpus and antrum. The specimens were used for determining gastric alcohol dehydrogenase activity, histological examination, and urease testing. Subjects with H. pylori infection ( n= 36) received medication to eradicate the infection, and repeat biopsies were taken 2 and 12 months later. Results: No significant difference in gastric alcohol dehydrogenase activity was found between men and women ( p > 0.05). Gastric alcohol dehydrogenase activity did not differ significantly between the subjects older than 50 years ( n= 39) and those 50 years or younger ( n= 37). In subjects with H. pylori infection, gastric alcohol dehydrogenase activity was significantly reduced in the antrum ( p < 0.05). After eradication of H. pylori, alcohol dehydrogenase activity in the antrum increased significantly within 2 months ( p < 0.01). Antral biopsies with the most pronounced inflammation and histological changes had significantly decreased alcohol dehydrogenase activity ( p < 0.05). In contrast, no significant differences were found in corpus. Conclusions: H. pylori infection is associated with decreased antral alcohol dehydrogenase activity, which seems to be related to the severity of the inflammatory changes in the mucosa. Eradication of H. pylori normalizes antral alcohol dehydrogenase activity within 2 months. pubtype: Academic Journal doctype: Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
