Helicobacter pylori is a major etiological agent in gastroduodenal disorders. H. pylori adhesion to human gastric mucosa is the initial step of H. pylori colonization. Inhibition of H. pylori adhesion is thus a therapeutic target in preventing H. pylori infection. We have previously established a method using the enzyme-linked immunosorbent assay to analyze quantitatively H. pylori adhesion to gastric epithelial cells. This method is suitable for screening antiadhesion agents. Some mucoprotective agents are proved to have antiadhesion effects in vitro, and they may modify H. pylori adhesion. This evidence gives us a useful clue to analyze the molecular mechanism of H. pylori adhesion to mucosa. Furthermore, in clinical trials, these mucoprotective agents enhanced the eradication rate when administered with antibiotics. In conclusion, the antiadhesion agents may have potential as therapeutic regimens against H. pylori infection.
