Machine perfusion appears to be particularly effective in expanding the use of extended criteria donor grafts by reducing and/or assessing the impact of ischemia-reperfusion injury on post-transplant graft function. There are 3 main temperature categories for liver machine perfusion: normothermic (37 °C), hypothermic (2–10 °C), and subnormothermic (20–25 °C). Each mode has advantages, disadvantages, and distinct beneficial effects on liver graft function. It is currently unknown which temperature range of perfusion is most effective with respect to improving extended criteria donor graft performance. Because periods of static cold storage (0–4 °C) may still be required, it is also unclear how to transition liver grafts through these perfusion temperature zones in a way that minimizes ischemia-reperfusion injury related to abrupt shifts in temperature. Moreover, perfusate requirements differ for each perfusion modality and temperature range. In this review, we discuss evidence that gradual temperature transitions that combine perfusion approaches may further improve outcomes for extended criteria liver grafts. We highlight unique considerations at each temperature range, approaches to transition between temperature zones, and temperature-dependent perfusate constraints. We propose that as liver machine perfusion gains widespread clinical implementation, the next phase of machine perfusion development will entail the optimization of combined perfusion protocols that efficiently traverse temperature ranges.</div></div>","PeriodicalId":100799,"journal":{"name":"Journal of Liver Transplantation","volume":"20 ","pages":"Article 100297"},"PeriodicalIF":0.0,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145158380","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, these factors complicate the accurate diagnosis of AATD-LD.

Previous studies have shown an influence of functional status on post-transplant outcomes in patients with advanced chronic liver disease. However, the impact of functional status on outcomes in an ACLF cohort is largely unknown.</div></div><div><h3>Methods</h3><div>The United Network for Organ Sharing (UNOS) Standard Transplant Analysis and Research (STAR) Database was utilized to study LT patients between 1987 and 2019. Patients were categorized by ACLF grades and further divided within each grade based on their level of assistance—no, some, or total—using KPS scores. The primary outcomes assessed were graft failure and all-cause mortality post-transplant. The secondary outcomes assessed were mortality secondary to specific organ system failures.</div></div><div><h3>Results</h3><div>Patients without ACLF requiring some (aHR 1.10, 95 %CI 1.04–1.17, <em>p</em> = 0.002) or total assistance (aHR 1.32, 95 %CI 1.22–1.43, <em>p</em> &lt; 0.001) showed increased risk of all-cause mortality. Those needing total assistance also faced a higher risk of graft failure (aHR 1.34, 95 %CI 1.13–1.58, <em>p</em> &lt; 0.001). However, functional status did not significantly impact post-transplant outcomes across all ACLF grades.</div></div><div><h3>Conclusion</h3><div>Functional status was not a significant predictor of post-transplant outcomes in ACLF patients, regardless of ACLF severity. <em>Poor functional scores in multi-organ failure likely reflect acute critical illness rather than baseline frailty.</em></div></div>","PeriodicalId":100799,"journal":{"name":"Journal of Liver Transplantation","volume":"19 ","pages":"Article 100286"},"PeriodicalIF":0.0,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144596636","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
