Use of HCV-Positive Livers in HCV-Negative Recipients.
Am J Gastroenterol
INTRODUCTION:There are only limited data on the survival outcomes after transplanting HCV RNA-positive liver into HCV RNA-negative recipients. The objective of our study was to determine whether there were graft and patient survival differences when HCV-negative patients received HCV RNA (nucleic acid amplification testing [NAT] positive)-positive liver grafts. METHODS:We queried the United Network for Organ Sharing data sets from January 2014 to December 2018, and recipients (N = 24,724) were stratified into 6 groups based on the status of HCV antibody and RNA of recipients and donors. The Cox proportional hazard regression was used to estimate the relationship between groups and 1-year post-LT graft or patient survival. RESULTS:During the study period, 1,358 recipients received NAT-positive liver grafts. Two hundred ten of the recipients were HCV negative. During the same period, 707 HCV antibody-positive but NAT-negative grafts were transplanted into 516 HCV-positive and 191 HCV-negative recipients. There were no differences in survival in HCV-positive recipients whether they received NAT-positive grafts (n = 1,148) or HCV antibody-negative/NAT-negative grafts (n = 6,321). Recipients of grafts from HCV antibody-positive/NAT-negative donors had similar survival whether recipients were HCV-negative patients (n = 191) or HCV-positive patients (n = 516), and their survival probabilities were similar to those of HCV-negative recipients (n = 6,321) receiving grafts from HCV antibody-negative/NAT-negative donors. Patient survival was lower (P = 0.049) when HCV-negative recipients (n = 210) received NAT-positive grafts compared with HCV-positive patients (n = 1,148) receiving NAT-positive grafts; however, when adjusted for recipient and donor characteristics, the difference was not significant. DISCUSSION:HCV-negative recipients receiving HCV-positive liver grafts (NAT positive) have excellent 1-year survival outcomes.
