Comparative Study
Anti-inflammatory signaling during ex vivo liver perfusion improves the preservation of pig liver grafts before transplantation.
Normothermic ex vivo liver perfusion (NEVLP) improves graft preservation by avoiding cold ischemia injury. We investigated whether the protective effects of NEVLP can be further improved by applying strategies targeted on reducing the activation of proinflammatory cytokines during perfusion. Livers retrieved under heart-beating conditions were perfused for 4 hours. ⋯ Only 1 early death occurred in each group (80% survival). In conclusion, addition of anti-inflammatory strategies further improves warm perfused preservation. Liver Transplantation 22 1573-1583 2016 AASLD.

Receiving Model for End-Stage Liver Disease (MELD) exception status for hepatocellular carcinoma (HCC) improves wait-list survival and probability of liver transplantation (LT). We aim to evaluate etiology-specific disparities in MELD exception, LT wait-list times, and post-LT outcomes among patients with HCC listed for LT. Using United Network for Organ Sharing 2004-2013 data, we evaluated adults (age > 18 years) with HCC secondary to hepatitis C virus (HCV), nonalcoholic steatohepatitis (NASH), alcoholic cirrhosis (EtOH), hepatitis B virus (HBV), combined EtOH/HCV, and combined HBV/HCV. ⋯ In conclusion, among US adults with HCC listed for LT, patients with NASH-HCC, EtOH-HCC, and EtOH/HCV-HCC were significantly less likely to have active MELD exception compared with HCV-HCC, and those without active exception had a lower likelihood of receiving LT. More research is needed to explore why NASH-HCC patients were less likely to have active MELD exception. Liver Transplantation 22 1356-1366 2016 AASLD.

Liver transplantation (LT) services in the United Kingdom are provided by 7 designated transplant centers for a population of approximately 64 million. The number of deceased organ donors has grown, and in 2014-2015 it was 1282 (570 donation after circulatory death and 772 donation after brain death). Donor risk is increasing. ⋯ National Health Service Blood and Transplant (NHSBT) promotes organ donation, maintains the organ donor register, obtains consent, and undertakes donor characterization and offering. NHSBT also maintains the national waiting list, develops and applies selection and allocation policies, monitors outcomes, and maintains the UK National Transplant Registry and commissions a national organ retrieval service.

Identifying which liver transplantation (LT) candidates with severe kidney injury will have a full recovery of renal function after liver transplantation alone (LTA) is difficult. Avoiding unnecessary simultaneous liver-kidney transplantation (SLKT) can optimize the use of scarce kidney grafts. Incorrect predictions of spontaneous renal recovery after LTA can lead to increased morbidity and mortality. ⋯ In a separate cohort of 98 LTA recipients with subacute kidney injury, we confirmed the association of WIT and lack of renal recovery (OR, 1.04; P = 0.04). In LT candidates with severe subacute renal injury, operative measures to minimize WIT may improve renal recovery potentially avoiding RRT and the need for subsequent kidney transplant.
