Abstract

Immune-related adverse events (irAEs) are complications of the use of immune checkpoint inhibitors (ICIs). ICI-associated gastritis is one of the main irAEs. The gastric microbiota is often related to the occurrence and development of many gastric diseases. Gastric microbiota adjustment may be used to treat gastric disorders in the future. Faecal microbiota transplantation can alter the gut microbiota of patients and has been used for treating ICI-associated colitis. Therefore, we propose gastric microbiota transplantation as a supplementary treatment for patients with ICI-associated gastritis who do not respond well to conventional therapy.

Keywords: Immune checkpoint inhibitor; Immune-related adverse events; Gastritis; Gastric microbiota transplantation; Probiotics

Core Tip: The gastric microbiota is often related to the occurrence and development of many gastric diseases. Faecal microbiota transplantation has been used for treating immune checkpoint inhibitor (ICI)-associated colitis. Therefore, gastric microbiota transplantation is a promising treatment for ICI-associated gastritis.
