Bloodstream infection after living donor liver transplantation

Abstract

There are no detailed studies on the prevalence or clinical magnitude of bloodstream infection (BSI) following living donor liver transplantation (LDLT). The study aimed to assess the incidence and analyze the risk factors for BSI after LDLT. Univariate and multivariate analyses were performed to identify the independent risk factors for postoperative BSI. Postoperatively, 26 episodes of BSI occurred in 21 of 242 studied adult patients by median postoperative d 35. Five patients had primary BSI. The source was unknown in 3 patients and an intravascular catheter in 2. The other 16 patients had secondary BSI. Secondary BSI was caused by surgical site infection in 8 patients, followed by intra-abdominal infection in 5, pneumonia in 2, and both surgical site infection and intra-abdominal infection in 1. The most frequent pathogen isolated was MRSA, which was detected in 4 patients. Surveillance culture detected the same isolates prior to BSI in 14 of 26 (50%) episodes. Diabetes mellitus and serum albumin level less than 2.4 g/dl independently predicted postoperative BSI. Perioperatively, screening for and taking actions against pathogen including MRSA should be performed in LDLT patients.
