To analyze the clinical characteristics of and identify specific risk
factors for enterococcal bacteremia following liver transplantation, i
ve performed a study in 405 consecutive Liver transplantation recipien
ts prophylaxed with a selective bowel decontamination regimen. Seventy
enterococcal bacteremias in 52 patients were identified. Enterococcus
faecalis (50) outnumbered Enterococcus faecium isolates (18), and 49%
of enterococcal bacteremias were polymicrobial, Biliary tree complica
tions were present in 34% of enterococcal bacteremias. Of the 15 death
s (29%) among the patients with enterococcal bacteremia, 4 were direct
ly associated with enterococcal bacteremia. In a multivariate analysis
, Roux-en-Y choledochojejunostomy (P=0.005), a cytomegalovirus-seropos
itive donor (P=0.013), prolonged transplantation time (P=0.02), and bi
liary stricturing (P=0.016) were identified as significant risk factor
s. Other risk factors identified in a univariate analysis included pri
mary sclerosing cholangitis (P=0.009) and symptomatic cytomegalovirus
infection (P=0.008). Enterococcal bacteremia is a frequent infectious
complication in liver transplantation recipients receiving selective b
owel decontamination. Its association with cytomegalovirus and biliary
tree abnormalities suggest specific areas for prophylactic interventi
on.
