Early bacteremia after solid organ transplantation.
OBJECTIVE: Bloodstream infections (BSI) are a major cause of morbidity and mortality after solid organ transplantation. Our aim was to analyze early BSI after solid organ transplantation. MATERIALS AND METHODS: A prospective cohort study included patients undergoing a kidney, simultaneous kidney-pancreas (SPK), or orthotopic liver transplantation (OLT) from 2003-2007. We prospectively collected demographic variables, underlying chronic diseases, transplantation procedures, and posttransplant complications. Recorded cases of BSI were defined as significant according to CDC criteria. Early BSIs were considered to be those appearing within 30 days posttransplantation. RESULTS: During the study period, we performed 902 transplantations: 474 renal, 340 liver, and 88 pancreas. Seventy episodes of early BSI were diagnosed in 67 patients (7.4%). The incidences of BSI according to the type of transplantation were: 4.8% in renal, 4.5% in SPK, and 12% in OLT (P < .001). Sixty-three percent of the bacteria isolated were gram-negative, the most frequent being Escherichia coli, of which 18 (54%) were extended-spectrum beta-lactamase-producing (ESBL), and Pseudomonas aeruginosa, of which 18 (31%) were multidrug-resistant. The most frequent gram-positive bacteria were coagulase-negative staphylococci (20%). The urinary tract was a frequent source of BSI (27%), followed by a catheter (18%). Two patients (3%) died, both liver recipients, but neither death was related to the BSI. CONCLUSIONS: In our setting, the incidence of early BSI among solid organ transplant recipients was high, especially liver recipients, but with low associated mortality. The most frequent sources of infection were urinary tract and catheter. Gram-negative BSI showed a high rate of multidrug resistance.
