The European trial investigating NEVLP as preservation technique for liver transplantation uses Gelafusine, a non-FDA approved bovine derived gelatin-based perfusion solution. In contrast, we report the first clinical NEVLP experience with Steen solution, a human-based albumin-based perfusate approved for lung perfusion.
Methods: Eight human liver grafts were preserved on the Metra device and perfused at 37C with Steen solution plus 3 units of erythrocytes. Epoprostenol, Taurocholic acid, heparin, and insulin were added during the perfusion. Data is expressed as median and range.
Results: Eight liver transplantations (6 NDD, 2 DCD) were performed. Donor age and BMI were 46 years (22-60yrs) and 24 (20-26). Preservation time was 11hr (9-13) with a perfusion duration of 6 hr (4-8hrs). Peak ALT level during perfusion was 444 U/L (152 – 1460U/L). Lactate decreased in all grafts during the perfusion. Bile production during perfusion was 10ml/hr (7-24ml/hr). AST and ALT levels 24hrs after transplantation were 312U/L (54 – 2858U/L) and 156U/L (21 – 1383U/L) respectively. All patients had excellent graft function with INR and bilirubin levels of 1.2 (1.05 – 1.3) and 1.3mg/dl (0.8-13mg/dl) 3 days after transplantation. ICU and hospital stay were 1day (0-5days) and 12days (9-26days). Two patients were fast tracked without post-transplant ICU care. No severe complication (Dindo-Clavien >3) occurred after transplantation.
Conclusion: Normothermic ex vivo perfusion with the Metra device using Steen solution is feasible and can result in good outcome after human liver transplantation. Using FDA approved Steen solution will avoid a potential regulatory barrier (the use of bovine based materials) to the clinical development of NEVLP in North America.
