Coagulation Factor V (FV) and ALT have emerged as important biomarkers in assessing liver function, yet their role as early predictors of graft loss has not been fully validated. The aim of this study is to conduct an internal validation of published results on the applicability of FV and ALT for diagnosing graft dysfunction and its predictive ability for graft loss within the first 90 days. We conducted a retrospective cohort study including 513 adult recipients from 2012 to 2023 at the Regional University Hospital of Málaga. FV and ALT levels were measured on postoperative day 2, and patients were categorized based on FV <37.5 and ALT >1539. The association with 90-day graft loss was analyzed. Graft loss occurred in 43 patients (8.4%) within the first 90 days. The combination of FV <37.5 and ALT >1539 on postoperative day 2 demonstrated a specificity of 99% and a test efficiency of 94% in predicting graft loss. Patients meeting both criteria had a 74-fold increased risk of graft loss, with most losses occurring within the first week, and a median survival of 4 days. These findings suggest that FV and ALT on postoperative day 2 are reliable early markers for predicting graft loss, enabling risk stratification and guiding critical decisions regarding early retransplantation in the immediate postoperative period.</p>","PeriodicalId":18072,"journal":{"name":"Liver Transplantation","volume":" ","pages":"489-497"},"PeriodicalIF":4.7,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142349438","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This was a single-center unblinded prospective pilot randomized controlled trial of adults (≥18 y) with liver transplant for alcohol-associated liver disease enrolled between 2021 and 2023, who were randomized 2:1 to the intervention of acamprosate (666 mg dose 3 times daily) or standard of care (SOC) over 14 weeks. Outcomes included safety (prevalence of adverse events [AEs]), feasibility (weekly survey response rate >60%), adherence (self-reported acamprosate use >60%), and efficacy (reduction in Penn Alcohol Craving Scale), and relapse-blood phosphatidylethanol (≥20 ng/mL/reported alcohol use) evaluated by standardized weekly surveys. The efficacy analysis was done in both the intention-to-treat (excluding withdrawals before medication administration) and per-protocol population (excluding withdrawals/<4 weeks participation). Of 78 participants who were approached, 30 enrolled (19 acamprosate and 11 SOC) with similar baseline characteristics. Eight participants withdrew (6 acamprosate before medication administration and 2 SOC). AEs were similar between acamprosate and SOC groups (92.3% vs. 90.0%, p > 0.99), including grade 3 AEs (53.9% vs. 60.0%, p > 0.99) with no reported grade 4/5 AEs. Survey response rates were similar in acamprosate versus SOC groups (61.0% vs. 76.0%, p = 0.19), and 69.0% were acamprosate adherents. Baseline Penn Alcohol Craving Scale values were low with no difference by the group in median absolute change in Penn Alcohol Craving Scale for intention-to-treat (0, IQR: -4 to 0 vs. 0, IQR: 0-0, p = 0.32), and per-protocol analyses (-1, IQR: -6 to 0 vs. 0, IQR: -0 to 0, p = 0.36). There was no reported or biochemical evidence of alcohol relapse. In this pilot study, preliminary data suggest that acamprosate may be safe and feasible.

The most challenging steps of the procedure include manual anastomosis of the suprahepatic vena cava, cuff anastomosis of the portal vein, and maintaining the anhepatic phase within 20 minutes. This study aims to provide detailed solutions to overcome these bottlenecks and introduces a modified magnetic device to facilitate safer and more efficient cuff anastomosis. We also describe the learning curve for beginners to achieve a 30-day survival rate exceeding 90% in MOLT. We demonstrate that MOLT can be mastered within eight months of continuous practice, with 7-day and 30-day survival rates improving from 0 to 96.7% and 0 to 93.3%, respectively. The entire procedure can be completed within 80 minutes.

However, the MELD score does not reflect functional status, leading to the evaluation of sarcopenia. While the L3 skeletal muscle index (SMIL3) is commonly used for assessment, the upper thigh skeletal muscle index (SMIUT) may better represent functional capacity. This retrospective study included 246 male LT recipients aged 40-60 from 2013 to 2015. Preoperative and postoperative muscle and fat areas at the L3 and upper thigh levels were quantified using artificial intelligence software. Clinical outcomes, including ventilator, ICU, and hospital days, were analyzed using logistic regression, while survival was evaluated using Cox regression and Kaplan-Meier curves. Longitudinal body composition changes were assessed over 5 years post-LT. SMIUT demonstrated stronger associations with hospital days (R²=0.378) than SMIL3 (R²=0.302). High SMIUT correlated with improved survival (P=0.02), unlike SMIL3. Longitudinal analysis revealed a significant divergence in SMIUT between survivors and non-survivors, whereas SMIL3 showed no significant changes. The visceral fat index at L3 (VFIL3) increased continuously, highlighting potential metabolic risks. SMIUT showed a similar or even stronger association with LT outcomes than SMIL3, effectively reflecting patient prognosis. SMIUT in the postoperative period also better reflected clinical status. Therefore, pre- and postoperative SMIUT is helpful for patient assessment and ongoing management in LT patients.</p>","PeriodicalId":18072,"journal":{"name":"Liver Transplantation","volume":" ","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143700829","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
