BACKGROUND: Donation after circulatory death (DCD) is related to a warm ischemia time and more complications compared with traditional donors (donation after brain death [DBD]).
METHODS: This study included biopsy samples retrospectively collected from November 2014 to December 2018 to compare histologic and biological markers of DCD and DBD liver grafts. The analysis includes marker of early apoptosis (p21), senescence (telomerase reverse transcriptase [TERT]), cell damage (caspase-3 active), endothelial damage (vascular endothelial growth factor), stem cell (CD90), hypoxia (HIF1A), inflammatory activation (COX-2), and cross-organ allograft rejection (CD44). A propensity score matching (PSM) was used to match patients receiving DCD livers to those receiving DBD livers. We analyzed the immunohistochemical initial liver damage-related warm ischemia time.
RESULTS: Positive staining expression of liver damage biomarkers (COX-2, CD44, TERT, HIF1A, and CD90) was found, but no significant differences were found between DCD and DBD and with ischemic cholangiopathy. After PSM, there was a significant relationship between CD90 and male donors (odds ratio [OR], 0.26; 95% confidence interval [CI], 0.07-0.91), TERT with donor sodium (OR, 1.11; 95% CI, 1.02-1.2), HIF1A with steatosis (OR, 0.33; 95% CI, 0.13-0.83), and CD44 with donor vasoactive drugs (OR, 0.36; 95% CI, 0.13-1) and glutamic oxaloacetic transaminase 1 week increase (OR, 1.01; 95% CI, 1-1.03).
CONCLUSIONS: DCD immunohistochemical initial liver damage was found to behave similarly to DBD. The increase in complications and cholangiopathy associated with warm ischemia could be related to a different later phenomenon.
