Cirrhotic cardiomyopathy (CCM), a prevalent comorbidity in adults with growing recognition in children, leads to hemodynamic perturbations that may compound the maladaptive physiology resulting in HRS-AKI. We aimed to explore a hepato-cardio-renal link in pediatric cirrhosis by examining peritransplant AKI, with a focus on CCM and Major Adverse Kidney Events at 28 days (MAKE28) in patients undergoing liver transplant (LT). This is a single-center, retrospective study of pediatric LT for biliary atresia (BA) from 2014 to 2020. Peri-LT AKI was defined as AKI within 7 days of LT. CCM was defined as left ventricular mass index to height of ≥95 g/m 2.7 , and/or relative wall thickness ≥0.42. Of 62 patients with BA (age 1.1 y [IQR: 0.8-2.4]), 29% had AKI, 61% had CCM, and 40% fulfilled MAKE28. Patients with AKI had higher blood product and vasoactive requirements, and lower ventilator-free days, compared with patients without AKI. The median length of stay was 133 (IQR: 54-121) versus 19.5 (IQR: 8.5-41) days for patients with AKI and without AKI, respectively ( p <0.001). CCM was more prevalent in those with peri-LT AKI (OR: 6.6, CI: 1.7-23, p =0.005). CCM remained significant after adjusting for age, markers of liver disease severity, and intraoperative events. Patients with BA face high morbidity peri-LT in the setting of prevalent AKI. The association between pediatric CCM and AKI suggests that cardiac dysfunction may be an independent risk factor for HRS-AKI. While studies are needed to further define the relationship between CCM and renal injury, pre-LT echocardiogram has the potential to facilitate timely identification and management of children at risk for HRS-AKI, and thereby promote renal recovery.</p>","PeriodicalId":520704,"journal":{"name":"Liver transplantation : official publication of the American Association for the Study of Liver Diseases and the International Liver Transplantation Society","volume":" ","pages":""},"PeriodicalIF":3.9,"publicationDate":"2026-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149003259","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}

The study included 2665 pediatric patients who underwent LDLT between January 2019 and December 2023 across 19 centers. Multivariable logistic regression was performed to identify risk factors, while time-dependent Cox models were used to assess the impact on survival. The median recipient age was 11 months (IQR: 6.3-34.6), and biliary atresia was the most common diagnosis (59.7%). Bile leak and anastomotic stricture occurred in 3.6% (n=97) and 1.9% (n=51) of patients, respectively. For bile leak, higher donor BMI was an independent predictor (OR 1.09 per kg/m 2 , 95% CI: 1.02-1.17). For anastomotic strictures, longer cold ischemia time was a significant predictor (OR 1.36 per hour, 95% CI: 1.03-1.79). Bile leak (aHR 4.39, 95% CI: 1.04-18.60) and biliary stricture (aHR 6.26, 95% CI: 1.58-24.80) were associated with worse graft survival. Patient survival was not significantly impacted by bile leak and stricture. Early complications more often required surgery, but survival and failure-to-rescue rates were similar regardless of treatment approach.

For eligible patients, liver transplantation (LT) represents a potentially curative option. Social determinants of health (SDOH) impact HCC outcomes, but their influence across the multi-step LT continuum remains poorly defined. We evaluated how SDOH measured through the Canadian Index of Multiple Deprivation (CIMD) and census metrics relate to LT access and tumor burden among HCC-referred patients. We analyzed a retrospective cohort of 576 patients with HCC referred for LT (2003-2021). Multivariable multinomial, linear, and competing risks regression examined relationships between SDOH and outcomes across the LT pathway. High residential instability was associated with presenting beyond Milan criteria at referral ( ptrend =0.02), and higher odds of non-listing due to psychosocial factors (quintile 5, RRR 4.74, p =0.02). Among waitlisted patients, higher residential instability scores predicted prolonged time-to-listing (β=0.08, p =0.04), whereas higher area-level marriage (β=-0.01, p =0.03) and private vehicle commuting rates (β=-0.01, p =0.002) predicted faster listing. In competing risks analysis (death/delisting as competitors), area-level CIMD dimensions did not influence LT probability once listed, and only a higher vehicle commuting rate remained significantly associated with transplantation (SHR 1.01, p =0.05). Ethnocultural quintile 2 was uniquely protective against psychosocial non-listing (RRR 0.14, p =0.01). SDOH inequities primarily restrict the pre-listing stages of the LT continuum, influencing tumor burden at referral, listing eligibility, and evaluation velocity, rather than post-listing organ allocation. Targeted interventions to ensure equitable transplantation access should focus on early social work navigation and logistical transportation support.</p>","PeriodicalId":520704,"journal":{"name":"Liver transplantation : official publication of the American Association for the Study of Liver Diseases and the International Liver Transplantation Society","volume":" ","pages":""},"PeriodicalIF":3.9,"publicationDate":"2026-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148972973","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}

For over 20 years, the Model for End-Stage Liver Disease (MELD) score and its variations have implemented a sickest-first ethical approach, enhancing waitlist survival rates and adding objectivity to the process. Nonetheless, ongoing disparities based on sex, race, and other structural factors reveal the shortcomings of relying on simplified, static models of disease severity. As LT progresses into an era increasingly shaped by artificial intelligence (AI) and machine learning (ML), these algorithms offer better predictions of waitlist mortality, post-transplant outcomes, and donor-recipient matching. However, higher predictive accuracy does not automatically lead to more ethical distribution. In this Perspective, we explore AI-assisted deceased donor liver allocation through the ethical principles of justice, respect for persons, and humanism. We review emerging AI/ML models proposed for LT, highlighting their potential advantages and risks, including amplification of historical inequities embedded in training data, lack of transparency, erosion of informed consent, and overreliance on algorithmic outputs at the expense of clinical judgment. We contend that AI should serve as decision support rather than a decision-maker, and that ethical implementation requires deliberate safeguards. We suggest a framework for responsibly integrating AI into liver allocation focused on fairness monitoring, transparency, explainability, human oversight, and multi-stakeholder governance. When applied properly, AI can potentially enhance both utility and equity in liver transplantation-but only if its use is guided by clear ethical principles and ongoing evaluation in real-world clinical settings.</p>","PeriodicalId":520704,"journal":{"name":"Liver transplantation : official publication of the American Association for the Study of Liver Diseases and the International Liver Transplantation Society","volume":" ","pages":""},"PeriodicalIF":3.9,"publicationDate":"2026-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148973057","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}
