[Indication of H. pylori eradication therapy--who should be treated?].
With increased evidence of H. pylori infection being deeply related with various gastric diseases, its curative therapy will be approved by social security foundation soon also in Japan. Japanese Society of Helicobacter reported a guideline for H. pylori diagnosis and treatment in July 2000. In the guideline, only peptic ulcers and low grade MALT lymphomas are recommended as an indication of H. pylori eradication and other diseases such as atrophic gastritis, post EMR state for early gastric cancer and post-operated stomach due to gastric cancer, hyperplastic polyps and non-ulcer dyspepsia, were not included. It is speculated that while benefit of eradication therapy for peptic ulcers and low grade MALT lymphomas has been supported by much clinical evidence, that for other diseases was judged not to be enough. Especially as to atrophic gastritis, eradication therapy might be considered in aspect of decreasing gastric cancer risk in Japan. Since accumulated epidemiological and experimental data strongly support its positive correlation with cancer risk, patients in high risk group for gastric cancer could be included for a target eradication therapy. In present, indication of the therapy should be clinically and socially decided according to individual patient.
