Emphasizing the importance of successful eradication of Helicobacter pylori on initial treatment.

Helicobacter pylori (H. pylori) infection is the most important risk factor for gastric cancer and plays an initiating role in the development of intestinal-type gastric cancer. Eradication of H. pylori significantly reduces the incidence and mortality of gastric cancer. International expert consensus recommends eradication treatment for all infected individuals unless competing considerations. However, large-scale H. pylori eradication treatments have led to increasing rates of resistance to multiple antibiotics, together with factors such as coccoid transformation, host CYP2C19 gene polymorphisms, and inappropriate treatment regimens, resulting in a gradual decline in H. pylori eradication rates. Currently, empirical and repeated eradication of H. pylori treatment is common in clinical practice, which will certainly lead to a further increase in antibiotic resistance, resulting in a great waste of medical resources and an increased psychological burden on patients and their relatives. Therefore, successful eradication of H. pylori on initial treatment should be given high priority, and the implementation of personalized treatment is essential. AJCR
