Abstract
This study investigates the relationship between blood group and waiting time until transplantation or death on the waiting list. All patients listed for liver transplantation in the Netherlands between 15 December 2006 and 31 December 2012, were included. Study variables were gender, age, year of listing, diagnosis, previous transplantations, blood group, urgency, and MELD score. Using a competing risks analysis, separate cumulative incidence curves were constructed for death on the waiting list and transplantation and used to evaluate outcomes.In 517 listings, the mean death rate per 100 patient-years was 10.4. A total of 375 (72.5% of all listings) were transplanted. Of all transplantations, 352 (93.9%) were ABO-identical and 23 (6.1%) ABO-compatible. The 5-year cumulative incidence of death was 11.2% (SE 1.4%), and of transplantation 72.5% (SE 2.0%). Patient blood group had no multivariate significant impact on the hazard of dying on the waiting list nor on transplantation. Age, MELD score, and urgency status were significantly related to the death on the waiting list and transplantation. More recent listing had higher probability of being transplanted. In the MELD era, patient blood group status does not have a significant impact on liver transplant waiting list mortality nor on waiting time for transplantation.

Variant outcomes of liver transplantation for hepatitis C virus patients in different age categories: impact of the model for end-stage liver disease score. JOURNAL OF HEPATO-BILIARY-PANCREATIC SCIENCES 2017; 24:206-216.

Abstract
BACKGROUND Whether the introduction of model for end-stage liver disease (MELD) has an effect on transplant outcome for different age categories remain unclear. METHODS We analyzed 49,762 adult hepatitis C virus (HCV) candidates through 1 January 1995 to 31 December 2012 from the Scientific Registry of Transplant Recipients. Patients were divided into four age categories (18-34, 35-49, 60-64, ≥65 years) in the pre-MELD era and MELD era, respectively. RESULTS Waiting list dropouts have decreased in the MELD era for all categories. A reduced trend in survival was observed for 18-34 years patients in the MELD era compared with the pre-MELD era, with 5-year intention-to-treat, overall and graft survival of 56.5%, 57.9%, 56.3% vs. 56.4%, 69.7%, 64.4% (P = 0.604, 0.034, and 0.071, respectively). For other age categories, survival rates were all superior in the MELD era. Cox-regression analysis showed values of hazard ratio for age increased with advanced age (all >1) in the pre-MELD era compared with the reference group (18-34 years), while these hazard ratios were <1 for overall and graft survival in MELD era. CONCLUSIONS Our study provides useful evidence that the introduction of MELD for liver allocation may adversely affect survival of specific HCV patients.
