How does H pylori eradication affect the microbiome?

It is clear that H. pylori eradication treatment has a profound impact on the microbiome of all segments of the gastrointestinal tract , and that this is not solely limited to the antibiotics used and any ensuing dysbiosis, but also the use of non-antibiotic agents, such as PPIs and bismuth. Prospective studies are necessary to elucidate how the microbial changes induced by H. pylori eradication therapy may impact human health, especially as the need for eradication therapy grows and success rates diminish. Long-term studies with clinical input are especially necessary in order to assess the true clinical relevance of the findings. These questions are particularly import-ant factors for those responsible for weighing up the positive and negative effects of large scale

What are the functions of gut bacteria?

Both resident gut bacteria and gastric acid play a significant role for a diverse range of gastro-intestinal functions including the production of energy, defense against pathogens, the modu-lation of the immune system, and support of the integrity of the gut mucosal barrier. These can all be affected by PPI therapy28. PPIs are able to modify the host microbiota in each segment of the gastrointestinal tract and can contribute to dysbiosis. In addition to the gastric achlorhydria caused by PPIs, these drugs promote the survival and migration of oral bacteria to lower areas of the GI tract, which may create pro-inflammatory microenvironment29.
