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":null,"pages":null},"PeriodicalIF":4.7,"publicationDate":"2024-09-10","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}

The regenerative process and function of congested areas, especially graft congestion associated with LT, are not well understood. Therefore, we created new rat models with congested areas in partially resected livers and orthotopically transplanted these livers into syngeneic rats to observe liver regeneration and function in congested areas. This study aimed to compare liver regeneration and the function of congested areas after liver resection and LT, and to explore a new approach to ameliorate the adverse effects of graft congestion. Although the congested areas after liver resection regenerated normally on postoperative day 7, the congested areas after LT had poor regeneration with abscess development on postoperative day 7. Necrotic areas in congested areas were larger after LT than after liver resection on postoperative days 1, 3, and 7 ( p < 0.05, p < 0.05, and p < 0.01, respectively). Although congested areas after liver resection did not affect survival, in the LT model, the survival of rats with congested areas was significantly poorer even with larger grafts than that of rats with smaller noncongested grafts ( p = 0.04). Hepatocyte growth factor administration improved the survival rate of rats with congested grafts from 41.7% to 100%, improved the regeneration of congested areas, and significantly reduced the size of necrotic areas ( p < 0.05). Thus, congested areas in liver grafts may negatively impact recipients. Short-term administration of hepatocyte growth factor may improve postoperative outcomes of recipients with graft congestion and contribute to more effective use of liver grafts (approval number: MedKyo-23137, Institutional Ethics Committee/Kyoto University).</p>","PeriodicalId":18072,"journal":{"name":"Liver Transplantation","volume":null,"pages":null},"PeriodicalIF":4.7,"publicationDate":"2024-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142120197","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.

Indocyanine green (ICG) imaging has been widely used in liver surgery, enabling the visualization of hepatic uptake and excretion through bile using near-infrared light. In this research, porcine livers under various ischemic conditions were examined during a 5-hour normothermic ex situ liver perfusion procedure, introducing ICG at 1 hour through the hepatic artery. These conditions included livers from heart-beating donors, donation after circulatory death (DCD) with warm ischemic durations of 60 minutes (DCD60) and 120 minutes (DCD120), as well as interventions utilizing tissue plasminogen activator in DCD120 cases (each n = 5). Distinct hepatic fluorescence patterns correlated with different degrees of ischemic injury ( p = 0.01). Low ICG uptake in the parenchyma (less than 40% of maximum intensity) was more prevalent in DCD120 (21.4%) compared to heart-beating donors (6.2%, p = 0.06) and DCD60 (3.0%, p = 0.02). Moreover, ICG clearance from 60 minutes to 240 minutes was significantly higher in heart-beating donors (69.3%) than in DCD60 (17.5%, p < 0.001) and DCD120 (32.1%, p = 0.01). Furthermore, thrombolytic intervention using tissue plasminogen activator in DCD120 resulted in noteworthy outcomes, including significantly reduced ALP levels ( p = 0.04) and improved ICG clearance ( p = 0.02) with a trend toward mitigating fibrin deposition similar to DCD60, as well as enhancements in bile production ( p = 0.09).
