Purpose: Liver transplantation is curative for hepatocellular carcinoma (HCC). Checkpoint inhibitor therapy (CPIT) has been used in unresectable HCC, but recent advances have demonstrated CPIT as an innovative method of downstaging advanced HCC with the caveat that CPIT prior to transplantation has risks including irreversible graft rejection. We report the outcomes of Mayo Clinic Arizona patients who underwent downstaging with CPIT., Methods: This retrospective chart review was conducted for Mayo Clinic Arizona patients who were diagnosed with HCC who underwent downstaging with CPIT with the goal of meeting criteria for transplantation., Results: We present nine cases with HCC outside Milan who underwent CPIT. Four received a transplant; one was delisted due to his exceptional therapeutic response. All received liver-directed therapy. Peak alpha-fetoprotein pre-CPIT ranged from 8-29,523 ng/mL, which decreased to 2.2-19.6 ng/mL on CPIT. CPIT included atezolizumab/bevacizumab, ipilimumab/nivolumab, nivolumab, and pembrolizumab; one patient received two regimens. CPIT was held prior to transplant at a median of 3 months. Three patients received methylprednisolone for immunosuppression induction; one received thymoglobulin. One patient developed acute cellular rejection at 5 weeks, 9 weeks, and 5 months post-transplant; given the late onset, these were not attributed to CPIT and were successfully treated. During an average follow-up of 16.5 months, no tumor recurrence has occurred., Conclusion: We describe nine patients with HCC outside Milan with inadequate response with liver-directed therapy, who achieved marked responses with CPIT, allowing for consideration of successful liver transplantation. Our case series supports the consideration of locoregional therapies and CPIT for downstaging to within transplant criteria., (© 2024.

Post-cross clamp late allocation (LA) liver allografts are at increased risk for discard for many reasons including logistical complexity. Nearest neighbor propensity score matching was used to match 2 standard allocation (SA) offers to every 1 LA liver offer performed at our center between 2015 and 2021. Propensity scores were based on a logistic regression model including recipient age, recipient sex, graft type (donation after circulatory death vs. donation after brain death), Model for End-stage Liver Disease (MELD), and DRI score. During this time, 101 liver transplants (LT) were performed at our center using LA offers. In comparing LA and SA offers, there were no differences in recipient characteristics including indication for transplant ( p = 0.29), presence of PVT ( p = 0.19), TIPS ( p = 0.83), and HCC status ( p = 0.24). LA grafts came from younger donors (mean age 43.6 vs. 48.9 y, p = 0.009) and were more likely to come from regional or national Organ Procurement Organizations (OPOs) ( p < 0.001). Cold ischemia time was longer for LA grafts (median 8.5 vs 6.3 h, p < 0.001). Following LT, there were no differences between the 2 groups in intensive care unit ( p = 0.22) and hospital ( p = 0.49) lengths of stay, need for endoscopic interventions ( p = 0.55), or biliary strictures ( p = 0.21). Patient (HR 1.0, 95% CI, 0.47-2.15, p = 0.99) and graft (HR 1.23, 95% CI, 0.43-3.50, p = 0.70) survival did not vary between the LA and SA cohorts. One-year LA and SA patient survival was 95.1% and 95.0%; 1-year graft survival was 93.1% and 92.1%, respectively. Despite the additional logistical complexity and longer cold ischemia time, LT outcomes utilizing LA grafts are similar to those allocated by means of SA. Improving allocation policies specific to LA offers, as well as the sharing of best practices between transplant centers and OPOs, are opportunities to further help minimize unnecessary discards., (Copyright © 2023 American Association for the Study of Liver Diseases.)

Background & Aims: Chronic liver disease (CLD) represents a major global health burden. We undertook this study to identify the factors associated with adverse outcomes in patients with CLD who acquire the novel coronavirus-2019 (COVID-19)., Methods: We conducted a multi-center, observational cohort study across 21 institutions in the United States (US) of adult patients with CLD and laboratory-confirmed diagnosis of COVID-19 between March 1, 2020 and May 30, 2020. We performed survival analysis to identify independent predictors of all-cause mortality and COVID-19 related mortality, and multivariate logistic regression to determine the risk of severe COVID-19 in patients with CLD., Results: Of the 978 patients in our cohort, 867 patients (mean age 56.9 ± 14.5 years, 55% male) met inclusion criteria. The overall all-cause mortality was 14.0% (n = 121), and 61.7% (n = 535) had severe COVID-19. Patients presenting with diarrhea or nausea/vomiting were more likely to have severe COVID-19. The liver-specific factors associated with independent risk of higher overall mortality were alcohol-related liver disease (ALD) (hazard ratio [HR] 2.42, 95% confidence interval [CI] 1.29-4.55), decompensated cirrhosis (HR 2.91 [1.70-5.00]) and hepatocellular carcinoma (HCC) (HR 3.31 [1.53-7.16]). Other factors were increasing age, diabetes, hypertension, chronic obstructive pulmonary disease and current smoker. Hispanic ethnicity (odds ratio [OR] 2.33 [1.47-3.70]) and decompensated cirrhosis (OR 2.50 [1.20-5.21]) were independently associated with risk for severe COVID-19., Conclusions: The risk factors which predict higher overall mortality among patients with CLD and COVID-19 are ALD, decompensated cirrhosis and HCC. Hispanic ethnicity and decompensated cirrhosis are associated with severe COVID-19. Our results will enable risk stratification and personalization of the management of patients with CLD and COVID-19. Clinicaltrials.gov number NCT04439084., (Copyright © 2021 AGA Institute.
