| Popis: | The incidence and mean score of Helicobacter pylori-related, active antroduodenitis, lesions of superficial antral epithelium and duodenal gastric-type metaplasia were higher in endoscopic biopsies from a large series of patients with duodenal ulcer, when compared with asymptomatic patients or patients with non-ulcer dyspepsia. In 65 out of 73 patients with duodenal ulcer who could be followed up, H. pylori was eradicated using a combination of amoxycillin, 3 g daily, metronidazole, 1 g daily, and omeprazole, 20 mg daily. Rapid and permanent (6-month follow-up) abolition of both gastroduodenitis activity and lesions of the gastric surface epithelium was observed in these 65 patients. There was also a progressive decrease in total immune-inflammatory cells but without a substantial change in duodenal gastric-type metaplasia. Similar, but transient and quantitatively less prominent, improvements were observed in the antroduodenal mucosa, which had been temporarily cleared of H. pylori by treatment with omeprazole alone. Conversely, increased gastritis activity, epithelial lesions and immune-inflammatory cell scores were found in the short term in the corpus mucosa, which was not cleared of H. pylori after omeprazole treatment. It is concluded that, of the various H. pylori-related mucosal changes, antroduodenitis activity and antral epithelial lesions most closely reflect the severity of mucosal damage and are probably the most important factors in duodenal ulcerogenesis. Their complete and rapid suppression after bacterial eradication may be a key factor in preventing ulcer relapse. |
