Abstract/OtherAbstract:
BACKGROUND: Recent studies have demonstrated that cytomegalovirus (CMV) infection and disease are associated with increased risk of graft loss and death in high-risk (donor CMV seropositive/recipient CMV seronegative) liver transplant recipients (LTR) despite effective antiviral chemoprophylaxis. Predictors of CMV infection and disease in this important population are incompletely defined. METHODS: A retrospective cohort study of 227 high-risk first LTR who received primary anti-CMV chemoprophylaxis during the first 100 days after transplant was performed. A large number of patient, donor, operative, and post-transplant potential risk factors were collected. Associations of potential risk factors for CMV infection or disease that occurred during the first year after transplant were assessed using Cox regression models. After Bonferroni adjustment for multiple testing, P-values ≤0.00125 (associations with CMV infection) and ≤0.00122 (associations with CMV disease) were considered as statistically significant. RESULTS: CMV infection and disease occurred in 91 (40%) and 43 (19%) of LTR, respectively. In multivariable analysis, increased risk of CMV infection was observed for patients with lower model for end-stage liver disease (MELD) score (P = 0.025), lower total bilirubin (P = 0.014), and longer operative time (P = 0.038), whereas increased risk of CMV disease was seen in patients with lower MELD score (P = 0.026), lower total bilirubin (P = 0.044), and lower international normalized ratio (P = 0.043). However, after adjustment for multiple testing, none of these findings approached statistical significance. CONCLUSION: Our results suggest that interventions designed to prevent CMV infection and disease should be applied to all high-risk LTR until more definitive predictors of these complications are identified.
