Helicobacter pylori (H. pylori) infection is common in organ transplant recipients, similar to the general population. Treatment is recommended to prevent peptic ulcers and MALT lymphoma post-transplant.
Area of Science:
- Gastroenterology
- Transplant Medicine
- Infectious Diseases
Background:
- Helicobacter pylori (H. pylori) infection is a known cause of upper gastrointestinal diseases.
- Individual variability exists in disease outcomes following H. pylori infection.
Purpose of the Study:
- To review and summarize the prevalence of H. pylori infection in organ transplant recipients.
- To examine the outcomes of H. pylori infection, including peptic ulcer and MALT lymphoma, after transplantation.
Main Methods:
- Literature review of published reports on H. pylori infection in organ transplant recipients.
- Summary of findings regarding prevalence and disease outcomes.
Main Results:
- H. pylori infection prevalence in solid-organ transplant recipients is comparable to non-transplant controls, potentially decreasing post-transplant.
- H. pylori infection is linked to peptic ulcer disease and MALT lymphoma post-transplantation, without increased incidence under immunosuppression.
- The association between H. pylori and de-novo gastric cancer post-transplantation requires further investigation.
Conclusions:
- Optimal management of H. pylori infection in solid-organ transplant recipients remains undetermined.
- H. pylori eradication is advised for positive recipients to prevent gastrointestinal diseases.
- Future studies should assess the efficacy of pre-transplant H. pylori eradication therapy.
