Organ dysfunction Organ dysfunction was reported in three studies [8, 13, 18] . One study showed a higher incidence of hepatic dysfunction (international normalized ratio > 1.5 or total bilirubin > 2.5 mg/ dL) in CMV infection group (70% vs. 36%, P < 0.047) [8] . In two studies, renal failure was observed more frequently in those with CMV infection (55 to 58% vs. 32 to 33%, P < 0.05 in each study) [13, 18] .
