The aim of this study was to evaluate the significance of post-transplant DSA as a predictor of liver fibrosis during long-term follow-up after pediatric LT. We evaluated the histological findings in 18 LT recipients who underwent liver biopsy after DSA screening. Liver fibrosis was scored based on the METAVIR fibrosis staging. Patients were divided into 2 groups based on histological findings, and clinical characteristics among patients with liver fibrosis were assessed. Of 18 patients, 7 were included in the fibrosis group. No significant between-group differences were found regarding peritransplant characteristics, including age, sex, primary disease, ABO incompatibility, and immunosuppressive regimen. Episodes of acute rejection and non-adherence to immunosuppressive drugs were comparable between both groups. The MFI for anti-DR DSA and positive rate were significantly higher in the fibrosis group (1655 vs 216; P = .019, 86% vs 27%; P = .012, respectively). MFI for anti-DQ DSA was higher in the fibrosis group, but non-significantly (2052 vs 384; P = .46). Post-transplant anti-DR DSA is associated with graft fibrosis during long-term follow-up. This finding seems useful for the implementation of valid histological examinations of liver grafts for patients with higher MFI, especially for anti-DR DSA, after pediatric LT.

These data suggest that C5aIP attenuates cross-talk between the complement and coagulation cascades through suppressing up-regulation of tissue factor expression on leukocytes in recipient livers but not on islet grafts, a process leading to improvement in islet engraftment. Therefore, C5aIP in combination with conventional anticoagulants could be a strong candidate strategy to control the instant blood-mediated inflammatory reaction induced in clinical islet transplantation.

Although larger sample sizes would be required to evaluate postoperative complication rate, these results indicate that both the right and left RDN could be performed with similar donor and recipient outcomes.

Given the shortage of deceased donor organs, we believe that LDLT is acceptable in an attempt to meet demand.

The prevalence of hypertension increased after LTx and pretransplant obesity was associated with several post-transplant metabolic abnormalities.

Objectives: Nonalcoholic steatohepatitis (NASH), which is a common and increasing indication for liver transplantation (LT), is known to recur after LT. Since the recurrence of NASH can lead to graft failure, the identification of predictive factors is needed and preventive strategies should be implemented. Methods: We retrospectively examined 95 patients who had undergone LT for NASH or alcoholic liver disease (ALD) as a primary indication. We evaluated peritransplant characteristics and histological findings 1-year post LT among liver transplant patients due to NASH or ALD. Results: Pre-LT body mass index (BMI) was higher and pre-LT diabetes was more prevalent in NASH patients than in ALD patients (p < .01). The difference of BMI persisted at 3 months and 1 year after LT. There were no differences between the groups regarding histopathological findings including the degree of steatosis and fibrosis in 1-year biopsy. In multivariate analysis, recipient age and 1-year BMI were independent risk factors for post-LT fatty liver disease development. Regarding predictive factors of NASH recurrence, the prevalence of pre-LT insulin-dependent diabetes was significantly higher in patients who developed NASH recurrence than those who did not. The increase of HbA1c at 1-year post-LT checkup was higher in patients who developed recurrence than those who did not, although the difference did not reach statistical significance. Conclusions: The results of this study suggest that insulin-dependent diabetes has detrimental effects on NASH recurrence following LT. Optimal glycemic control should be recommended, but studies are needed to prove its preventive effect on NASH recurrence.
