- W2346103614 abstract "To investigate the prevalence of Helicobacter pylori infection in 50 cirrhotic patients with biopsy-proven cirrhosis with and without portal hypertensive gastropathy and to study whether or not the effects of H. pylori colonization of the stomach on gastric acid and pepsin secretion, serum gastrin and pepsinogen I levels, gastric mucus, and gastric emptying contributed to the development of portal hypertensive gastropathy in cirrhotics.All patients underwent an upper GI endoscopy followed by determination of basal and pentagastrin and insulin-stimulated gastric acid and pepsin secretion and serum gastrin and pepsinogen I levels. The gastric biopsies were stained to detect H. pylori infection, portal hypertensive gastropathy, and gastritis. The amount of gastric mucus was estimated by a microanalytical technique. The rate of gastric emptying was assessed by the radionuclide method using a semi-solid meal.Thirty-three (66%) patients had endoscopic evidence of portal hypertensive gastropathy, 10 with the severe (20%) and 23 with mild form (46%). Twenty (40%) patients had histological evidence of H. pylori infection. Eleven out of 33 (33%) patients with endoscopic portal hypertensive gastropathy had microscopic evidence of H. pylori infection. Eighteen out of 20 (90%) patients with chronic active gastritis had concomitant H. pylori colonization. In contrast, the gastric mucosa was histologically normal in 21 of the 30 patients (70%) not infected with H. pylori. Marked hypochlorhydria and reduced pepsin secretion associated with a tendency to hypergastrinemia were observed in cirrhotic patients colonized with H. pylori compared with those without. However, there was no significant difference in serum pepsinogen I concentrations, the ratio of polymeric to degraded gastric mucus, or the rate of gastric emptying between cirrhotics with and without H. pylori colonization of the stomach. Furthermore, these parameters were not significantly different in patients with portal hypertensive gastropathy with and without H. pylori infection.These observations suggest that H. pylori infection is unlikely to be involved in the pathogenesis of portal hypertensive gastropathy." @default.
