In Japan, the scarcity of deceased donors leads to reliance on living donors, often resulting in smaller grafts. Managing portal venous pressure (PVP) is critical to prevent fatal posttransplant complications. This study explored the possibility of predicting intraoperative PVP. We analyzed 475 living donor liver transplant cases from 2006 to 2023, excluding those with acute liver failure or prior splenectomy or splenic artery embolization. Patients were divided into a training group (n = 425) and a test group (n = 50). We evaluated the correlation between preoperative factors and PVP at laparotomy to predict PVP at laparotomy and closure. The predictive model was validated with the test group data. PVP at laparotomy could be predicted using correlated preoperative factors: prothrombin time ( p < 0.001), predicted splenic volume ( p < 0.001), and presence of a portosystemic shunt ( p = 0.002), as follows: predicted PVP at laparotomy (mm Hg)=25.818 - 0.077 × (prothrombin time [%]) + 0.004 × (predicted splenic volume [mL]) - 2.067 × (1: with a portosystemic shunt) ( p < 0.001; R = 0.346). In addition, PVP at closure could be predicted using correlated operative factors, including measured PVP at laparotomy, as follows: predicted PVP at closure (mm Hg)=14.268 + 0.149 × (measured PVP at laparotomy [mm Hg]) - 0.040 × (GV/SLV [%]) - 0.862 × (1: splenectomy [if yes]) - 3.511 × (1: splenic artery ligation without splenectomy [if yes]) ( p < 0.001; R = 0.339). This study demonstrated the feasibility of predicting intraoperative PVP using preoperative factors in patients with decompensated cirrhosis undergoing liver transplant. This predictive approach could refine surgical planning, potentially improving patient outcomes.</p>","PeriodicalId":18072,"journal":{"name":"Liver Transplantation","volume":" ","pages":"428-437"},"PeriodicalIF":4.7,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141590689","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}

Little is known about long-term outcomes. We performed a nationwide retrospective cohort study to evaluate short-term and long-term outcomes of post-OLT pregnancies. The secondary aim was to assess predictors for adverse pregnancy outcomes. A composite outcome of preeclampsia, preterm birth, low birth weight, and neonatal intensive care unit admission was made. Survival of women who received a transplant at <50 years of age with and without pregnancy after OLT were compared (Dutch Organ Transplantation Registry data). Descriptive statistics, regression analysis, Kaplan-Meier and log-rank analysis, and generalized estimating equation analysis were used. Among the included 70 women with 113 pregnancies >20 weeks of gestation, hypertension occurred in 20% and preeclampsia in 12%. The live birth rate was 87%; 33% were preterm, and 23% had low birth weight. Long-term follow-up (median 10 y [IQR: = 4-14]) showed small changes in serum creatinine and bilirubin ( p < 0.001). Sixteen mothers (23%) died during follow-up (median 8 y [IQR: = 4-12]), with all their children aged <18 years. No difference in survival was found when comparing women with and without pregnancy after OLT. The composite outcome occurred in 43/98 of pregnancies. Higher body mass index (BMI) and maternal age at conception increased the composite outcome risk (OR: 1.24, p < 0.01, and OR: 1.25, p = 0.01, respectively). To conclude, pregnancy after OLT does not seem to influence long-term outcomes of graft, kidney function, or patient survival in most cases. However, although pregnancy does not seem to impact survival after OLT, we do show that a substantial number of children will lose their mothers early in life. We believe this is important for pregnancy couseling of patients with an OLT and their partners.</p>","PeriodicalId":18072,"journal":{"name":"Liver Transplantation","volume":" ","pages":"508-520"},"PeriodicalIF":4.7,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142154488","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.

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}
