Onset of Donor Warm Ischemia Time in Donation After Circulatory Death Liver Transplantation: Hypotension or Hypoxia?

Marit Kalisvaart, Jubi E. Haan, Wojciech G. Polak, Jan N. M. IJzermans, Diederik Gommers, Herold J. Metselaar, Jeroen Jonge – 24 August 2018 – The aim of this study was to investigate the impact of hypoxia and hypotension during the agonal phase of donor warm ischemia time (DWIT) on hepatic ischemia/reperfusion injury (IRI) and complications in donation after circulatory death (DCD) liver transplantation. A retrospective single‐center study of 93 DCD liver transplants (Maastricht type III) was performed.

Management of Coagulation and Anticoagulation in Liver Transplantation Candidates

Patrick Northup, Bethany Reutemann – 24 August 2018 – Hemostasis is a complex balance of clot formation and dissolution that is largely modulated by protein synthesis and degradation in the liver. In the state of end‐stage liver disease, there is a disruption of the hemostatic system due to hepatic protein synthetic dysfunction. Because historical clinical laboratory testing often only analyzes a portion of the hemostasis system, the clinician may be misled into believing that cirrhosis patients are imbalanced with a tendency toward bleeding.

Class II Human Leukocyte Antigen Epitope Mismatch Predicts De Novo Donor‐Specific Antibody Formation After Liver Transplantation

Chandrashekhar A. Kubal, Richard Mangus, Burcin Ekser, Plamen Mihaylov, Brian Ceballos, Nancy Higgins, Naga Chalasani, Marwan Ghabril, Lauren Nephew, Andrew Lobashevsky – 24 August 2018 – Formation of de novo donor‐specific antibodies (dn‐DSAs) has been associated with longterm immunologic complications after liver transplantation (LT). We hypothesized that human leukocyte antigen (HLA) epitope/eplet mismatch (MM) is a marker of immunogenicity and a risk factor for dn‐DSA formation.

Serum Angiopoietin‐2 Predicts Mortality and Kidney Outcomes in Decompensated Cirrhosis

Andrew S. Allegretti, Xavier Vela Parada, Guillermo A. Ortiz, Joshua Long, Scott Krinsky, Sophia Zhao, Bryan C. Fuchs, Mozhdeh Sojoodi, Dongsheng Zhang, S. Ananth Karumanchi, Sahir Kalim, Sagar U. Nigwekar, Ravi I. Thadhani, Samir M. Parikh, Raymond T. Chung – 23 August 2018 – Acute kidney injury in decompensated cirrhosis has limited therapeutic options, and novel mechanistic targets are urgently needed. Angiopoietin‐2 is a context‐specific antagonist of Tie2, a receptor that signals vascular quiescence.
