Abstract
BACKGROUND

Marginal donation after circulatory death (DCD) liver grafts are carefully used to combat the constant shortage of donors. Clinically, the worst outcomes are mainly related to severe ischemia-reperfusion-injury and the dangerous effect of various inflammatory cytokines (CK). The machine perfusion (MP) is a promising device to rescue these grafts.

AIM

To analyze the role of MP connected to a sorbent cartridge (PerSorb®) and used for very damaged DCD pig livers.

METHODS

Seven grafts were procured from pigs from a slaughterhouse. Grafts were made very marginal with at least 60 minutes of donor warm ischemia time and 24 hours of static-cold ischemia time: (1) 3 grafts were perfused in hypothermic MP with PerSorb (Sorb); (2) 2 other grafts in hypothermic MP (HMP) without the cartridge (NoSorb); and (3) The other 2 livers stored in the ice box (NoTreat). The CK were measured at HMP start (T0) and at the end (Tend). Biopsies were taken at T0 and Tend.

RESULTS

All 5 grafts treated with HMP had a negative lactate trend after 3 hours of treatment (8.83 at T0 vs 6.4 at Tend of Sorb; 15 at T0 vs 5.45 at Tend for NoSorb, P value > 0.05). At Tend, both Sorb and NoSorb groups had better hemodynamic parameters, comparable between the two groups. Enzyme-linked immunosorbent assay analysis showed a reduction of monocyte chemotactic protein-1, tumor necrosis factor-alpha and interleukin-1β for NoSorb group at Tend and a complete downregulation to physiological levels of the same CK in Sorb livers after 3 hours of treatment. Biopsies showed a reduction of the perisinusoidal edema for the Sorb grafts compared with the NoSorb livers.

CONCLUSION

These data suggest a potential protective role of treatment of grafts with MP and sorbent cartridge in reducing the inflammatory response after a severe ischemic injury.

Core Tip: Marginal donation after circulatory death liver grafts are carefully used to fight the constant shortage of donors. Clinically, the worst outcomes are mainly related to severe ischemia-reperfusion-injury and the dangerous effect of various inflammatory cytokines (CK). The machine perfusion (MP) is a promising device to rescue these grafts. Recently, a new ex-situ MP device incorporating a filter cartridge to the machine has been considered. It was tested on pigs, and it appears to reduce the CK during the treatment of standard liver grafts. The purpose of the study was the analysis of the role of the CK cartridge connected to the MP and used to preserve extremely marginal pig grafts during processing in the MP. The results were analyzed biochemically and histologically.
