Investigating the gut microbiome's role in antibiotic-resistant infections after lung or liver transplants

Official title: The Gut Microbiome in Carbapenem-Resistant Enterobacteriaceae Colonization, Persistence, Infection, and Tolerance after Lung or Liver Transplantation

Funded at University of Pittsburgh at Pittsburgh · NIH-11006352 · Data updated 2026-11-12

This study is looking at how the bacteria in your gut might affect the presence of tough-to-treat infections in people who have had lung or liver transplants, with the goal of finding ways to better manage antibiotic resistance for these patients.

Who could benefit from this research

Could help

Ideal candidates for this research are individuals who have received a lung or liver transplant and are at risk for infections caused by carbapenem-resistant bacteria.

Less likely to help

Patients who have not undergone lung or liver transplantation or those without risk factors for CRE infections may not benefit from this research.

What this research studies

This research focuses on understanding how the gut microbiome influences the colonization and persistence of carbapenem-resistant Enterobacteriaceae (CRE) in patients who have undergone lung or liver transplantation. The study aims to identify genetic traits of CRE that contribute to infections and tolerance to antibiotics, as well as the gut microbiota changes associated with these conditions. By analyzing stool samples and patient data, researchers hope to uncover patterns that could lead to better management of antibiotic resistance in transplant recipients.

Why it matters

Potential benefit: If successful, this research could lead to improved strategies for preventing and treating antibiotic-resistant infections in transplant patients.

How similar studies have gone: Previous research has shown promising results in understanding the gut microbiome's role in antibiotic resistance, suggesting that this approach could yield valuable insights.
