Background: Liver transplantation is the definitive treatment for defined stage hepatocellular carcinoma (HCC) in cirrhotic patients. Loco-regional therapy (LRT) may be considered before transplantation to prevent the disease progression and the patient from dropping out of the waiting list. This study aims to evaluate the impact of repeated pretransplant LRTs on the long-term outcomes in HCC liver transplant recipients. Methods: Between 2004 and 2019, living donor liver transplantation (LDLT) recipients with viable HCC on the explant livers were enrolled. Uni- and multivariate analysis was performed with the Cox regression model to stratify the risk factors associated with HCC recurrence and patent survival after LDLT. Results: A total of 124 patients were enrolled, in which 65.3% (n = 81) were Barcelona Clinic Liver Cancer classification stage B or D and 89% (n = 110) had advanced fibrosis or cirrhosis on the explanted livers. After a median follow-up of 41 months (IQR: 24–86.5), there were 18 cases (13.7%) of HCC recurrence. Univariate analysis showed that the model of end-stage liver disease and Child-Turcotte-Pugh score, pretransplant alpha-fetoprotein value (>500 ng/ml), repeated pretransplant LRTs (N > 4), increased tumor numbers and maximal size, presence of microvascular invasion, and the histological grading of the tumors are risk factors of inferior outcomes. In multivariate analysis, only repeated pretransplant LRTs (N > 4) had a significant impact on both the overall- and recurrence-free survival. The impact of pretransplant LRT was consistently significant among subgroups based on their LRT episodes (N = 0, 1–4, >4 respectively). Conclusion: Repeated LRT for HCC can be associated with the risk of tumor recurrence and inferior patient survival after LDLT in cirrhotic patients. Early referral of those eligible for transplantation may improve the treatment outcomes in these patients.
Introduction: During the coronavirus disease 2019 (COVID-19) pandemic, COVID-19 vaccination is essential for controlling the outbreak and preventing severe disease. However, there are still uncertainties about the safety of COVID-19 vaccination in individuals with chronic liver disease. Case Presentation: Three patients with hepatitis B virus (HBV) infection presented to our hospital with acute-on-chronic liver failure (ACLF) due to HBV flare after COVID-19 vaccination (mRNA-1273 and ChAdOx1 nCoV-19). Their COVID-19 antibodies were tested by Elecsys Anti-SARS-CoV-2 S immunoassay, which showed good response after full two-dose course of vaccine. One patient refused the test. The patients’ clinical conditions deteriorated during hospitalization. Patient 1 received Entecavir (Baraclude) 1 mg/day upon presentation, but the serum bilirubin level and international normalized ratio (INR) kept increasing. He was comatose in one week and underwent urgent living donor liver transplantation. Patient 2 was on regular Entecavir (Baraclude) 0.5 mg/day and was increased to 1 mg/day upon admission. The serum bilirubin level and INR kept increasing, and he developed grade 3 hepatic encephalopathy in three weeks. The patient then received urgent living donor liver transplantation. Patient 3 received Entecavir (Baraclude) 1 mg/day upon presentation. Her serum bilirubin and INR kept increasing, and her mental status altered in a week. She did not undergo liver transplantation for her old age. Conclusions: It is not still unclear whether there is a cause-and-effect relationship between COVID-19 vaccination and HBV infection flare. Furthermore, the mechanism of COVID-19 vaccine-induced HBV reactivation is not established. Further studies are needed in this regard. However, during the COVID-19 pandemic, prophylactic antiviral therapy for HBV infection before COVID-19 vaccination should be considered.
Background: Liver transplantation (LT) is being increasingly performed for alcohol-related liver disease (ALD). It is unclear whether the increasing frequency of LTs in ALD patients has a negative impact on deceased-donor (DDLT) allocation and whether the current policy of 6 months of abstinence before transplantation effectively prevents recidivism after transplantation or improves long-term outcomes. Methods: A total of 506 adult LT recipients, including 97 ALD patients, were enrolled. The outcomes of ALD patients were compared with those of non-ALD patients. The 97 ALD patients were further divided into group A (6-month abstinence) and group N (nonabstinence) based on the pretransplant alcohol withdrawal period. The incidence of relapsed drinking and the long-term outcomes were compared between the two groups. Results: The prevalence of LT for ALD significantly increased after 2016 (27.0% vs 14.0%; p < 0.01), but the frequency of DDLT for ALD remained unchanged (22.6% vs 34.1%, p = 0.210). After a median follow-up of 56.9 months, patient survival was comparable between the ALD and non-ALD patients (1, 3, and 5 years posttransplant: 87.6%, 84.3%, and 79.5% vs 82.8%, 76.6%, and 72.2%, respectively; p = 0.396). The results were consistent irrespective of the transplant type and disease severity. In ALD patients, 22 of the 70 (31.4%) patients reported relapsed drinking after transplantation, and the prevalence in group A had a higher tendency than that in group N (38.3% vs 17.4%, p = 0.077). Six months of abstinence or nonabstinence did not result in a survival difference, and de novo malignancies were the leading cause of late patient death in ALD patients. Conclusion: LT achieves favorable outcomes for ALD patients. Six months of abstinence pretransplant did not predict the risk of recidivism after transplantation. The high incidence of de novo malignancies in these patients warrants a more comprehensive physical evaluation and better lifestyle modifications to improve long-term outcomes.
