Antibiotic Stewardship Based on Colonization with Multi-Drug-Resistant Bacteria in Liver Transplantation: A Narrative Review

In solid organs post-transplant, bacterial infections can complicate the course of recovery with devastating consequences, such as graft loss and death. We provide an expert review on early post-liver transplant bacterial infections, with a focus on infections with multi-drug-resistant organism (MDRO) etiologies. Best practice recommendations are derived from a combination of available evidence and expert consensus. The main challenge in managing antibiotic therapy arises in patients with severe clinical conditions but negative MDRO screening results, as well as in those with positive MDRO screening results but uncomplicated infections. With the aim of shedding light on these "gray areas", we propose an algorithm where the patient is stratified as being at low risk or high risk of developing an MDRO infection.
