Microbial etiology of early onset pulmonary infection after liver transplantation / 中国感染与化疗杂志

ABSTRACT

Objective To explore the microbial etiology of early onset pulmonary infection after liver transplantation.Methods The 40 episodes of early onset pulmonary infection in 75 patients receiving liver transplantation in our hospital were reviewed and analyzed retrospectively.Results The incidence rate of pulmonary infection was 53.30% in these patients.A total of 54 pathogens were isolated,including 41(75.9%)strains of bacteria and 13(24.1%)fungal isolates.Gram-negative bacillus ac- counted for 68.3%(n=28)of the bacterial isolates,11(39.3%)of which were positive for extended spectrum?-lactamase. Gram-positive coccus accounted for 31.7%(n=13).Seven (58.3%)of the staphylococcal strains were methicillin-resistant. Conclusions The incidence of pulmonary infection is high early af- ter liver transplantation.Most of the isolated pathogens are drug resistant.Culture of sputum or secretion of lower respiratory tract and bedside X-ray examination are useful for the diagnosis.
