Résumé
Pneumonia in liver transplant recipients is one of the most common infections in the early phase after transplantation. The diagnosis is based on clinical signs combined with positive microbiological samples taken from the lower respiratory tract. However, the role of bacterial colonization is not clear, nor is its association with pneumonia or its long-term consequences. The aim of this study was to investigate the association between positive microbiological findings and clinically relevant pneumonia and analyze different clinical and laboratory parameters for their association with pneumonia in liver transplant recipients. This was a retrospective analysis of 266 adult orthotopic liver transplantations between January 2008 and December 2013. A multidisciplinary in-house specialist panel established and confirmed the diagnosis of clinically relevant pneumonia in microbiologically positive patients. Of the 266 transplantations analyzed, 54 patients (20%) showed microbiologically positive trachea-bronchial cultures during the first 21 days after liver transplantation. Of those 54 patients, 24 (44.4%) had pneumonia as rated by the multidisciplinary specialist panel. Presence of gram-negative Enterobacteriaceae (P = .013) and positive chest radiologic findings (P = .035) were associated with pneumonia in microbiological-positive patients. Although patients with pneumonia had the lowest long-term survival, those without pneumonia but with positive microbiological cultures had still worse survival compared with the Model for End-Stage Liver Disease-matched control group without positive cultures (P = .012). Gram-negative Enterobacteriaceae and positive radiologic findings were associated with pneumonia in liver transplant recipients with positive microbiological trachea-bronchial cultures. Recipients with bacterial colonization without pneumonia also showed decreased long-term survival.

BACKGROUND
BACKGROUND
Pneumonia in liver transplant recipients is one of the most common infections in the early phase after transplantation. The diagnosis is based on clinical signs combined with positive microbiological samples taken from the lower respiratory tract. However, the role of bacterial colonization is not clear, nor is its association with pneumonia or its long-term consequences. The aim of this study was to investigate the association between positive microbiological findings and clinically relevant pneumonia and analyze different clinical and laboratory parameters for their association with pneumonia in liver transplant recipients.
METHODS
METHODS
This was a retrospective analysis of 266 adult orthotopic liver transplantations between January 2008 and December 2013. A multidisciplinary in-house specialist panel established and confirmed the diagnosis of clinically relevant pneumonia in microbiologically positive patients.
RESULTS
RESULTS
Of the 266 transplantations analyzed, 54 patients (20%) showed microbiologically positive trachea-bronchial cultures during the first 21 days after liver transplantation. Of those 54 patients, 24 (44.4%) had pneumonia as rated by the multidisciplinary specialist panel. Presence of gram-negative Enterobacteriaceae (P = .013) and positive chest radiologic findings (P = .035) were associated with pneumonia in microbiological-positive patients. Although patients with pneumonia had the lowest long-term survival, those without pneumonia but with positive microbiological cultures had still worse survival compared with the Model for End-Stage Liver Disease-matched control group without positive cultures (P = .012).
CONCLUSIONS
CONCLUSIONS
Gram-negative Enterobacteriaceae and positive radiologic findings were associated with pneumonia in liver transplant recipients with positive microbiological trachea-bronchial cultures. Recipients with bacterial colonization without pneumonia also showed decreased long-term survival.
