Ulcer and gastritis

As in previous years, developments in the field of ulcers and gastritis ha-ve been dominated by new findings related to Helicobacter pylori. With the decrease in the frequency of H. pylori infection, the relative proportion of non-H. pylori ulcers has increased. Attempts to reduce the endoscopy workload by H. pylori or CagA screening have not been successful, and are probably pi-advised. Tt has become increasingly clear that curing H. pylori infection will not automatically lead to complete relief of symptoms in patients with duodenal ulcer disease. Post-therapy confirmation of cure will probably become the norm. Studies comparing omeprazole to misoprostol or ranitidine for nonsteroidal anti-inflammatory drug (NSAID) ulcer prevention in true NSAID ulcers have shown that omeprazole is equal to full-dose misoprostol for ulcer healing and to the lowest useful dose of misoprostol for ulcer prevention. H-2-receptor antagonists cannot be recommended for NSAID ulcer healing or prevention. Elimination of H. pylori increases the prevalence of gastroesophageal reflux disease in a population in such a way that superficially, there appears to be a choice between more gastroesophageal reflux disease or multifocal atrophic gastritis. The risk of developing adenocarcinoma of the esophagogastric junction is many times (10-fold to 60-fold) less than the risk of developing gastric cancer from CagA-positive H. pylori infection with multifocal atrophic gastritis - the "protective" lesion.
