Abstract

BACKGROUND:

Cytomegalovirus (CMV) has been inconsistently associated with recurrent hepatitis C virus (HCV) after liver transplant (LT).

METHODS:

A retrospective study of 347, donor or recipient CMV seropositive, first LT recipients transplanted for HCV was performed to evaluate the associations of CMV infection and disease occurring within 1-year of LT with the primary endpoints of allograft inflammation grade ≥2 and fibrosis stage ≥2. Associations were evaluated using multivariable Cox regression models.

RESULTS:

CMV infection and disease occurred in 111 (32%) and 24 (7%) patients, respectively. Hepatic allograft inflammation grade ≥2 and fibrosis stage ≥2 occurred in 221 (64%) and 140 (40%) patients, respectively. CMV infection was associated with increased risk of fibrosis stage ≥2 (relative risk [RR], 1.52; P=0.033). CMV disease was associated with increased risk of inflammation grade ≥2 (RR, 3.40; P<0.001), and although not significant, with fibrosis stage ≥2 (RR, 2.03; P=0.052). These associations did not differ significantly according to recipient CMV seropositivity.

CONCLUSIONS:

Our results support an association between CMV infection and disease with recurrence of HCV after LT. Investigation of prevention of CMV infection and disease as a strategy to mitigate recurrent HCV in LT recipients is warranted.
