Purpose Of Review:
The purpose of this review is to summarize recent advances in the understanding of the interplay between gut dysbiosis and MDRO colonization and infection in SOT patients.
Recent Findings:
Recent studies have added complementary metagenomics, internal transcribed spacer sequencing, metabolomics, and pathway analysis to descriptive microbiome profiling. Enhanced ecologic frameworks have identified microbial, functional, and clinical signatures associated with MDRO colonization and infection. Microbiome-targeting interventions are emerging as strategies to reduce morbidity associated with MDRO infection.
Summary:
MDRO infection is a significant cause of post-transplant mortality. Persistent gut dysbiosis peri-transplant reduces colonization resistance and predisposes patients to adverse clinical outcomes. Understanding the dynamics of this process will aid in the care of these high-risk patients.
