The rate and causes of hospital readmissions after liver transplantation (LT) remain largely unknown in the United States. Adult patients (n 5 11,937; 43.1% of all LT cases) undergoing LT from 2007 to 2011 were examined with a linkage of the University HealthSystem Consortium and Scientific Registry of Transplant Recipients databases to determine the incidence and risk factors for 30-day readmissions and utilization metrics 90 days after LT. The overall 30-day hospital readmission rate after LT was 37.9%, with half of patients admitted within 7 days after discharge. Readmitted patients had worse overall graft and patient survival with a 2-year follow-up. Multivariate analysis identified risk factors associated with 30-day hospital readmission, including a higher Model for End-Stage Liver Disease score, diabetes at LT, dialysis dependence, a high donor risk index allograft, and discharge to a rehabilitation facility. After adjustments for donor, recipient, and geographic factors in a hierarchical model, we found significant variation in readmission rates among hospitals ranging from 26.3% to 50.8% (odds ratio, 0.53-1.90). In the 90-day analysis after LT, readmissions accounted for $43,785 of added costs in comparison with patients who were not readmitted in the first 90 days. This is the first national report showing that more than one-third of LT recipients are readmitted to their center within 30 days and that readmissions are associated with center variation and increased resource utilization.

In this prospective cohort of non-HCV liver recipients receiving grafts from HCV antibody-positive/NAT-negative donors, the incidence of HCV transmission was 16%, with the highest risk conferred by donors who died of drug overdose; given the availability of safe and highly effective antiviral therapies, use of such organs could be considered to expand the donor pool. (Hepatology 2018;67:1673-1682).

The use of donation after circulatory death (DCD) liver allografts has been constrained by limitations in the duration of donor warm ischemia time (DWIT), donor agonal time (DAT), and cold ischemia time (CIT). The purpose of this study is to assess the impact of longer DWIT, DAT, and CIT on graft survival and other outcomes in DCD liver transplants. The Scientific Registry of Transplant Recipients was queried for adult liver transplants from DCD donors between 2009 and 2015. Donor, recipient, and center variables were included in the analysis. During the study period, 2107 patients underwent liver transplant with DCD allografts. In most patients, DWIT and DAT were <30 minutes. DWIT was <30 minutes in 1804 donors, between 30 and 40 minutes in 248, and >40 minutes in 37. There was no difference in graft survival, duration of posttransplant hospital length of stay, and readmission rate between DCD liver transplants from donors with DWIT <30 minutes and DWIT between 30 and 40 minutes. Similar outcomes were noted for DAT. In the multivariate analysis, DAT and DWIT were not associated with graft loss. The predictors associated with graft loss were donor age, donor sharing, CIT, recipient admission to the intensive care unit, recipient ventilator dependence, Model for End‐Stage Liver Disease score, and low‐volume transplant centers. Any CIT cutoff >4 hours was associated with increased risk for graft loss. Longer CIT was also associated with a longer posttransplant hospital stay, higher rate of primary nonfunction, and hyperbilirubinemia. In conclusion, slightly longer DAT and DWIT (up to 40 minutes) were not associated with graft loss, longer posttransplant hospitalization, or hospital readmissions, whereas longer CIT was associated with worse outcomes after DCD liver transplants.

Antibody-mediated rejection (AMR) is an uncommon, but challenging type of rejection after solid organ transplantation. We review three cases of AMR in ABO- compatible liver transplant recipients. These cases were characterized by severe acute rejection resistant to steroids and antithymocyte globulin, histologic evidence of plasma cell infiltrates, C4d positivity and high serum anti-HLA donor-specific antibodies. All three patients were treated with bortezomib, a proteasome inhibitor effective in depleting plasma cells. After treatment, all patients had improved or normal liver function tests, resolution of C4d deposition and significant decline in their HLA donor-specific antibodies.

SummaryThe aim of this study was to analyze the impact of morbid obesity in recipients on peritransplant resource utilization and survival outcomes. Using a linkage between the University HealthSystem Consortium and Scientific Registry of Transplant Recipients databases, we identified 12 445 patients who underwent liver transplantation (LT) between 2007 and 2011 and divided them into two cohorts based on recipient body mass index (BMI; <40 vs. ≥40 kg/m²). Recipients with BMI ≥40 comprised 3.3% (n = 416) of all LTs in the studied population. There were no significant differences in donor characteristics between two groups. Recipients with BMI ≥40 were significant for being female, diabetic, and with NASH cirrhosis. Patients with a BMI ≥40 had a higher median MELD score, limited physical capacity, and were more likely to be hospitalized at LT. BMI ≥40 recipients had higher post-LT length of stay and were less often discharged to home. With a median follow-up of 2 years, patient and graft survival were equivalent between the two groups. In conclusion, morbidly obese LT recipients appear sicker at time of LT with an increase in resource utilization but have similar short-term outcomes.

Elderly LT recipients accounted for <3% of all LTs performed during 2007-2011. Selected elderly recipients have perioperative outcomes and survival similar to those in younger adults.
