Early Allograft Dysfunction | Evaluation of Preimplantation Portal Vein and Hepatic Artery Flushing With Tacrolimus

Early Allograft Dysfunction research study

What is the primary objective of this study?

The purpose of this study is to determine whether the Tacrolimus added to histidine-tryptophan-ketoglutarate (HTK) solution given through intraportal and intraarterial infusion during back-table procedure is capable of reducing the degree of early allograft liver dysfunction, as assessed by postoperative levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), during first 7 postoperative days and by serum and histochemical markers of liver injury and inflammation.

Who is eligible to participate?

Inclusion Criteria: - Donor: age 15-65 years macrovesicular steatosis < 40% (macroscopy or biopsy) sodium <165 mmol/l ICU stay and ventilation < 11 days cold ischemia time < 13 hours AST < 200 U/l ALT < 200 U/l bilirubin < 50 μmol/l application of norepinephrine is allowed - Recipient age: 18-69 Exclusion Criteria: Recipient: - live donor liver transplant - reduced and split grafts - multi organ failure

Study Interventions

Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.

Drug:Tacrolimus1000 ml of HTK solution (Custodiol, Dr. Franz Köhler Chemie GmBH) cooled to 2-4˚C containing 20 ng/ml Tacrolimus would be given through intraportal (under gravity pressure of 40 cm H2O) and intraarterial infusion (under pressure of 40-50 mm Hg) followed by intraportal infusion of 200 ml 5% solution of Albumin containing 20 ng/ml Tacrolimus under gravity pressure of 40 cm H2O.

Study Arms

Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.

Tacrolimus + HTKDuring back-table operation 1000 ml of HTK solution cooled to 2-4˚C containing 20 ng/ml Tacrolimus would be given through intraportal (under gravity pressure of 40 cm H2O) and intraarterial infusion (under pressure of 40-50 mm Hg) followed by intraportal infusion of 200 ml 5% solution of Albumin containing 20 ng/ml Tacrolimus under gravity pressure of 40 cm H2O.

HTKDuring back-table operation 1000 ml of HTK solution cooled to 2-4˚C would be given through intraportal (under gravity pressure of 40 cm H2O) and intraarterial infusion (under pressure of 40-50 mm Hg) followed by intraportal infusion of 200 ml 5% solution of Albumin under gravity pressure of 40 cm H2O.
