Prognostic Scores for Ursodeoxycholic Acid-Treated Patients Predict Graft Loss and Mortality in Recurrent Primary Biliary Cholangitis after Liver Transplantation.

BACKGROUND/AIM: Recurrent primary biliary cholangitis (rPBC) develops in approximately 30% of patients and negatively impacts graft and overall patient survival after liver transplantation (LT). There is a lack of data regarding the response rate to ursodeoxycholic acid (UDCA) in rPBC. We evaluated a large, international, multi-center cohort to assess the performance of scores for PBC to predict the risk of graft and overall survival after LT in patients with rPBC. METHODS: A total of 332 patients with rPBC after LT were evaluated from 28 centres across Europe, North and South America. The median age at the time of rPBC was 58.0 years [IQR 53.2 - 62.6], and 298 patients (90%) were females. The biochemical response was measured with serum levels of alkaline phosphatase (ALP) and bilirubin, and Paris-2, GLOBE and UK-PBC scores at 1 year after UDCA initiation. RESULTS: During a median follow-up of 8.7 years [IQR 4.3 - 12.9] after rPBC diagnosis, 52 patients (16%) had graft loss and 103 (31%) died. After 1 year of UDCA initiation the histological stage at rPBC (HR, 3.97, 95%CI 1.36-11.55, P=0.01), use of prednisone (HR 3.18, 95%CI 1.04-9.73, P=0.04), ALP xULN (HR 1.59, 95%CI 1.26-2.01, P<0.001), Paris-2 criteria (HR 4.14, 95%CI 1.57-10.92, P=0.004), GLOBE score (HR 2.82, 95%CI 1.71-4.66, P<0.001), and the UK-PBC score (HR 1.06, 95%CI 1.03-1.09, P<0.001) were associated with graft survival in the multivariate analysis. Similar results were found in the overall survival analysis. CONCLUSION: Patients with rPBC and disease activity as indicated by standard PBC risk scores have impaired outcomes, supporting efforts to treat recurrent disease in similar ways to pre-transplant PBC. IMPACT AND IMPLICATIONS: One in three people who have liver transplantation for primary biliary cholangitis develop recurrent disease in their new liver. Patients with recurrent primary biliary cholangitis and incomplete response to ursodeoxycholic acid according to conventional prognostic scores have worse clinical outcomes, with higher risk of graft loss and mortality in similar ways to the disease before liver transplantation. Our results emphasized supporting efforts to treat recurrent disease in similar ways to pre-transplant primary biliary cholangitis.

Liver injury after SARS-CoV-2 vaccination: Features of immune-mediated hepatitis, role of corticosteroid therapy and outcome.

BACKGROUND AND AIMS: A few case reports of autoimmune hepatitis-like liver injury have been reported after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination. We evaluated clinical features, treatment response and outcomes of liver injury following SARS-CoV-2 vaccination in a large case series. APPROACH AND RESULTS: We collected data from cases in 18 countries. The type of liver injury was assessed with the R-value. The study population was categorized according to features of immune-mediated hepatitis (positive autoantibodies and elevated immunoglobulin G levels) and corticosteroid therapy for the liver injury. We identified 87 patients (63%, female), median age 48 (range: 18-79) years at presentation. Liver injury was diagnosed a median 15 (range: 3-65) days after vaccination. Fifty-one cases (59%) were attributed to the Pfizer-BioNTech (BNT162b2) vaccine, 20 (23%) cases to the Oxford-AstraZeneca (ChAdOX1 nCoV-19) vaccine and 16 (18%) cases to the Moderna (mRNA-1273) vaccine. The liver injury was predominantly hepatocellular (84%) and 57% of patients showed features of immune-mediated hepatitis. Corticosteroids were given to 46 (53%) patients, more often for grade 3-4 liver injury than for grade 1-2 liver injury (88.9% vs. 43.5%, p = 0.001) and more often for patients with than without immune-mediated hepatitis (71.1% vs. 38.2%, p = 0.003). All patients showed resolution of liver injury except for one man (1.1%) who developed liver failure and underwent liver transplantation. Steroid therapy was withdrawn during the observation period in 12 (26%) patients after complete biochemical resolution. None had a relapse during follow-up. CONCLUSIONS: SARS-CoV-2 vaccination can be associated with liver injury. Corticosteroid therapy may be beneficial in those with immune-mediated features or severe hepatitis. Outcome was generally favorable, but vaccine-associated liver injury led to fulminant liver failure in one patient.

Metabolic dysfunction outperforms ultrasonographic steatosis to stratify hepatocellular carcinoma risk in patients with advanced hepatitis C cured with direct-acting antivirals.

BACKGROUND AND AIMS: Metabolic dysfunction (MD)-associated fatty liver disease has been proposed to identify individuals at risk of liver events irrespectively of the contemporary presence of other liver diseases. The aim of this study was to examine the impact of MD in patients cured of chronic hepatis C (CHC). PATIENTS AND METHODS: We analysed data from a real-life cohort of 2611 Italian patients cured of CHC with direct antiviral agents and advanced liver fibrosis, without HBV/HIV, transplantation and negative for hepatocellular carcinoma (HCC) history (age 61.4 ± 11.8 years, 63.9% males, median follow-up 34, 24-40 months). Information about ultrasonographic steatosis (US) after sustained virological response was available in 1978. RESULTS: MD affected 58% of patients, diagnosed due to the presence of diabetes (MD-diabetes, 19%), overweight without diabetes (MD-overweight, 37%) or multiple metabolic abnormalities without overweight and diabetes (MD-metabolic, 2%). MD was more frequent than and not coincident with US (32% MD-only, 23% MD-US and 13% US-only). MD was associated with higher liver stiffness (p < 0.05), particularly in patients with MD-diabetes and MD-only subgroups, comprising older individuals with more advanced metabolic and liver disease (p < 0.05). At Cox proportional hazard multivariable analysis, MD was associated with increased risk of HCC (HR 1.97, 95% CI 1.27-3.04; p = 0.0023). Further classification according to diagnostic criteria improved risk stratification (p < 0.0001), with the highest risk observed in patients with MD-diabetes. Patients with MD-only appeared at highest risk since the sustained virological response achievement (p = 0.008), with a later catch-up of those with combined MD-US, whereas US-only was not associated with HCC. CONCLUSIONS: MD is more prevalent than US in patients cured of CHC with advanced fibrosis and identifies more accurately individuals at risk of developing HCC.

A territory-wide opportunistic, hospital-based HCV screening in the general population from northern Italy: The 1969-1989 birth-cohort.

BACKGROUND AND AIM: The World Health Organization (WHO) goal of Hepatitis C Virus (HCV) elimination by 2030 rose awareness about the need of screening plans, worldwide. In Italy, graduated screening starting from people born in 1969-1989 might be the most-effective strategy. We performed an opportunistic HCV screening study in the general population attending health facilities in Lombardy region, Northern Italy. METHODS: This is a prospective, multicenter, territory-wide, opportunistic study supported by the Regional Government of Lombardy, Italy. Between June 2022 and December 2022, all subjects born in 1969-1989, hospitalized or accessing blood collection centres were offered anti-HCV and HCV-RNA tests. Patients with known anti-HCV positivity and/or previous anti-HCV treatment were excluded. Demographic features were uploaded into a regional web-based platform. RESULTS: In total, 120 193 individuals were screened in 75 centres. Mean age was 44 (±6) years, 65.2% were females, 83.7% were tested at blood collection centres. Anti-HCV tested positive in 604 (0.50%) subjects: mean age 47 (±5), 51.1% females. HCV seroprevalence was higher in males (p < 0.00001), elderly (p < 0.00001) and in- vs. outpatients (p = 0.0009). HCV-RNA was detectable in 125 out of 441 (28.3%) anti-HCV positive subjects. Actively infected patients were 46 (±6) years old, mainly males (56.8%). The overall prevalence of active HCV infection was 0.10%, higher in elderly (p = 0.0003) and in in-patients (p = 0.0007). Among 93 HCV-RNA positive patients, the median age was 48 years, 58% males, 62% Italian born, median HCV-RNA levels were 6,1 log IU/mL, liver stiffness measurement (LSM) values 5.5 (3.1-29.9) kPa and ALT levels 48 U/L. CONCLUSIONS: The prevalence of active HCV infection in the 1969-1989 population attending health facilities in Lombardy was low. Most viremic patients were Italian-born, with mild liver disease but high-HCV-RNA levels. Due to the higher prevalence in the elderly, the extension of such opportunistic screening programs to lower birth cohorts would be warranted.

Extended criteria liver donation after circulatory death with prolonged warm ischemia: a pilot experience of normothermic regional perfusion and no subsequent ex-situ machine perfusion.

BACKGROUND: Livers from controlled donation after circulatory death (cDCD) with very prolonged warm ischemic time (WIT) are regularly transplanted after abdominal normothermic regional perfusion (aNRP) plus ex-situ machine perfusion (MP). Considering aNRP as in-situ MP, we investigated whether the results of a pilot experience of extended criteria cDCD liver transplantation (LT) with prolonged WIT, with aNRP alone, were comparable to the best possible outcomes in low-risk cDCD LT. METHODS: Prospectively collected data on 24 cDCD LT, with aNRP alone, were analyzed. RESULTS: The median total and asystolic WIT were 51 and 25 min. Measures within benchmark cut-offs were: median duration of surgery (5.9 h); median intraoperative transfusions (3 units of red blood cells); need for renal replacement therapy (2/24 patients); median intensive care stay (3 days); key complications; overall morbidity, graft loss, and retransplantation up to 12 months; 12-month mortality (2/21 patients). The median hospital stay (33 days, due to logistics) and mortality up to 6 months (2/24 patients, due to graft-unrelated causes) exceeded benchmark thresholds. CONCLUSIONS: This pilot experience suggests that livers from cDCD with very prolonged WIT that appear viable during adequate quality aNRP may be safely transplanted, with no need for ex-situ MP, with considerable resource savings.

Implementation of HCV screening in the 1969-1989 birth-cohort undergoing COVID-19 vaccination.

BACKGROUND AND AIM: The World Health Organization (WHO) goal of hepatitis C virus (HCV) elimination by 2030 relies on the scaling-up of both identification and linkage to care of the infected population, worldwide. In Italy, the estimated burden of HCV carriers who are unaware of their infection amounts to 200 000 persons, a projection that reinforces the need for broadening population access to effective screening programmes. METHODS: A pivotal screening programme targeting subjects born between 1969 and 1989 has been conducted in Lombardy, Northern Italy, where point-of-care (POC) testing was offered for free concomitantly to COVID-19 vaccination. RESULTS: Amongst 7219 subjects born between 1969 and 1989 who underwent HCV screening through POC, 7 (0.10%) subjects tested anti-HCV positive: 5 (0.07%) had confirmed anti-HCV positivity (Table 1) and 4 of them (0.05%) were HCV-RNA positive by standard confirmation tests. CONCLUSIONS: This pivotal study demonstrated the feasibility of a POC-based anti-HCV screening programme in young adults undergoing COVID-19 vaccination. The prevalence of HCV infection in subjects born in the 1969-1989 cohort in Italy seems to be lower than previously estimated. Whether the extension of this programme to subjects born before 1969 could lead to improved screening effectiveness should be a matter of debate.

Liver transplantation in patients with non-neoplastic portal vein thrombosis: 20 years of experience in a single center.

BACKGROUND: The Yerdel classification is widely used for describing the severity of portal vein thrombosis (PVT) in liver transplant (LT) candidates, but might not accurately predict transplant outcome. METHODS: We retrospectively analyzed data regarding 97 adult patients with PVT who underwent LT, investigating whether the complexity of portal reconstruction could better correlate with transplant outcome than the site and extent of the thrombosis. RESULTS: 79/97 (80%) patients underwent thrombectomy and anatomical anastomosis (TAA), 18/97 (20%) patients underwent non-anatomical physiological reconstructions (non-TAA). PVT Yerdel grade was 1-2 in 72/97 (74%) patients, and 3-4 in 25/97 (26%) patients. Univariate analysis revealed higher 30-day mortality, 90-day mortality, 1-year mortality, and a higher rate of severe early complications in the non-TAA group than in the TAA group (p = .018, .001, .014, .009, respectively). In the model adjusted for PVT Yerdel grade, non-TAA remained independently associated with higher 30-day, 90-day, and 1-year mortality (p = .021, .007, and .015, respectively). The portal vein re-thrombosis and overall patient and graft survival rates were similar. DISCUSSION: In our experience, the complexity of portal reconstruction better correlated with transplant outcome than the Yerdel classification, which did not even appear to be a reliable predictor of the surgical complexity and technique.

Meet-Test-Treat for HCV management: patients' and clinicians' preferences in hospital and drug addiction services in Italy.

BACKGROUND: It has been estimated that the incidence of chronic hepatitis C virus (HCV) will not decline over the next 10 years despite the improved efficacy of antiviral therapy because most patients remain undiagnosed and/or untreated. This study aimed to investigate the opinion of relevant target populations on the practicability, effectiveness and best modalities of the test-and-treat approach in the fight against HCV in Italy. METHODS: A survey was delivered to patients with HCV from the general population, patients from drug addiction services, hospital physicians and healthcare providers for drug addiction services. RESULTS: For both hospital clinicians and SerD HCPs, tolerability is shown as the most important feature of a suitable treatment. Time to treatment (the time from first contact to initiation of treatment) is deemed important to the success of the strategy by all actors. While a tolerable treatment was the main characteristic in a preferred care pathway for general patients, subjects from drug addiction services indicated that a complete Meet-Test-Treat pathway is delivered within the habitual care center as a main preference. This is also important for SerD HCPs who are a strong reference for their patients; hospital clinicians were less aware of the importance of the patient-HCP relationship in this process. CONCLUSION: The health system is bound to implement suitable pathways to facilitate HCV eradication. A Meet-Test-Treat program within the drug addiction services may provide good compliance from subjects mainly concerned with virus transmission.

Characterization of compliance phenotypes in COVID-19 acute respiratory distress syndrome.

BACKGROUND: Coronavirus disease 2019-associated acute respiratory distress syndrome (COVID-19 ARDS) seems to differ from the "classic ARDS", showing initial significant hypoxemia in the face of relatively preserved compliance and evolving later in a scenario of poorly compliant lungs. We tested the hypothesis that in patients with COVID-19 ARDS, the initial value of static compliance of respiratory system (Crs) (1) depends on the previous duration of the disease (i.e., the fewer days of illness, the higher the Crs and vice versa) and (2) identifies different lung patterns of time evolution and response to prone positioning. METHODS: This was a single-center prospective observational study. We enrolled consecutive mechanically ventilated patients with a diagnosis of COVID-19 who met ARDS criteria, admitted to intensive care unit (ICU). Patients were divided in four groups based on quartiles of initial Crs. Relationship between Crs and the previous duration of the disease was evaluated. Respiratory parameters collected once a day and during prone positioning were compared between groups. RESULTS: We evaluated 110 mechanically ventilated patients with a diagnosis of COVID-19 who met ARDS criteria admitted to our ICUs. Patients were divided in groups based on quartiles of initial Crs. The median initial Crs was 41 (32-47) ml/cmH2O. No association was found between the previous duration of the disease and the initial Crs. The Crs did not change significantly over time within each quartile. Positive end-expiratory pressure (PEEP) and driving pressure were respectively lower and greater in patients with lower Crs. Prone positioning significantly improved PaO2/FiO2 in the 4 groups, however it increased the Crs significantly only in patients in lower quartile of Crs. CONCLUSIONS: In our cohort, the initial Crs is not dependent on the previous duration of COVID-19 disease. Prone positioning improves oxygenation irrespective to initial Crs, but it ameliorates respiratory mechanics only in patients with lower Crs.

COVID-19 in liver transplant candidates: pretransplant and post-transplant outcomes - an ELITA/ELTR multicentre cohort study.

OBJECTIVE: Explore the impact of COVID-19 on patients on the waiting list for liver transplantation (LT) and on their post-LT course. DESIGN: Data from consecutive adult LT candidates with COVID-19 were collected across Europe in a dedicated registry and were analysed. RESULTS: From 21 February to 20 November 2020, 136 adult cases with laboratory-confirmed SARS-CoV-2 infection from 33 centres in 11 European countries were collected, with 113 having COVID-19. Thirty-seven (37/113, 32.7%) patients died after a median of 18 (10-30) days, with respiratory failure being the major cause (33/37, 89.2%). The 60-day mortality risk did not significantly change between first (35.3%, 95% CI 23.9% to 50.0%) and second (26.0%, 95% CI 16.2% to 40.2%) waves. Multivariable Cox regression analysis showed Laboratory Model for End-stage Liver Disease (Lab-MELD) score of ≥15 (Model for End-stage Liver Disease (MELD) score 15-19, HR 5.46, 95% CI 1.81 to 16.50; MELD score≥20, HR 5.24, 95% CI 1.77 to 15.55) and dyspnoea on presentation (HR 3.89, 95% CI 2.02 to 7.51) being the two negative independent factors for mortality. Twenty-six patients underwent an LT after a median time of 78.5 (IQR 44-102) days, and 25 (96%) were alive after a median follow-up of 118 days (IQR 31-170). CONCLUSIONS: Increased mortality in LT candidates with COVID-19 (32.7%), reaching 45% in those with decompensated cirrhosis (DC) and Lab-MELD score of ≥15, was observed, with no significant difference between first and second waves of the pandemic. Respiratory failure was the major cause of death. The dismal prognosis of patients with DC supports the adoption of strict preventative measures and the urgent testing of vaccination efficacy in this population. Prior SARS-CoV-2 symptomatic infection did not affect early post-transplant survival (96%).

Third-party bone marrow-derived mesenchymal stromal cell infusion before liver transplantation: A randomized controlled trial.

Mesenchymal stromal cells (MSC) have emerged as a promising therapy to minimize the immunosuppressive regimen or induce tolerance in solid organ transplantation. In this randomized open-label phase Ib/IIa clinical trial, 20 liver transplant patients were randomly allocated (1:1) to receive a single pretransplant intravenous infusion of third-party bone marrow-derived MSC or standard of care alone. The primary endpoint was the safety profile of MSC administration during the 1-year follow-up. In all, 19 patients completed the study, and none of those who received MSC experienced infusion-related complications. The incidence of serious and non-serious adverse events was similar in the two groups. Circulating Treg/memory Treg and tolerant NK subset of CD56bright NK cells increased slightly over baseline, albeit not to a statistically significant extent, in MSC-treated patients but not in the control group. Graft function and survival, as well as histologic parameters and intragraft expression of tolerance-associated transcripts in 1-year protocol biopsies were similar in the two groups. In conclusion, pretransplant MSC infusion in liver transplant recipients was safe and induced mild positive changes in immunoregulatory T and NK cells in the peripheral blood. This study opens the way for a trial on possible tolerogenic efficacy of MSC in liver transplantation. ClinicalTrials.gov identifier: NCT02260375.

On-treatment serum albumin level can guide long-term treatment in patients with cirrhosis and uncomplicated ascites.

BACKGROUND & AIMS: The ANSWER study reported that long-term albumin administration in patients with cirrhosis and uncomplicated ascites improves survival. During treatment, serum albumin increased within a month and remained stable thereafter. In this post hoc analysis, we aimed to determine whether on-treatment serum albumin levels could guide therapy. METHODS: Logistic regression was used to assess the association between baseline serum albumin and mortality, as well as to determine on-treatment factors associated with mortality and to predict the achievement of a given on-treatment serum albumin level. Survival was assessed by Kaplan-Meier estimates and second-order polynomial regression. Patients whose on-treatment serum albumin remained below normal were compared with a subset of patients from the control arm matched by principal score. RESULTS: Baseline serum albumin was closely associated with 18-month mortality in untreated patients; albumin treatment almost effaced this relationship. On-treatment serum albumin and MELD-Na at month 1 were the sole independent variables associated with mortality. Second-order polynomial regression revealed that survival improved in parallel with increased 1-month on-treatment serum albumin. Kaplan-Meier estimations showed that any value of 1-month on-treatment serum albumin (0.1 g/dl intervals) in the range 2.5-4.5 g/dl discriminated patient survival. In the normal range of serum albumin, the best discriminant value was 4.0 g/dl. Compared to untreated patients, survival even improved in patients whose on-treatment serum albumin remained below normal. CONCLUSION: Baseline serum albumin per se should not guide the decision to start albumin therapy. Conversely, 1-month on-treatment serum albumin levels are strongly associated with outcomes and could guide the use of albumin - 4.0 g/dl being the target threshold. However, even patients whose serum albumin remains below normal benefit from long-term albumin administration. LAY SUMMARY: The ANSWER study has shown that long-term albumin administration improves survival and prevents the occurrence of major complications in patients with cirrhosis and ascites. This study shows that the achievement of these beneficial effects is related to a significant increase in serum albumin concentration. Even though the best results follow the achievement of a serum albumin concentration of 4 g/dl, a survival benefit is also achieved in patients who fail to normalise serum albumin.

High rates of sustained virological response despite premature discontinuation of directly acting antivirals in HCV-infected patients treated in a real-life setting.

In routine clinical practice, hepatitis C virus-infected patients can prematurely discontinue the prescribed regimen for several reasons. The aim of our study was to investigate sustained virological response (SVR12) rates in patients who prematurely discontinued directly acting antiviral (DAA) regimens and to assess the shortest effective duration of DAA able to lead to SVR12. We retrospectively collected the SVR rates of patients, registered in the NAVIGATORE-Lombardia Network database from January 2015, who discontinued DAAs before the predefined end of treatment. Overall, we included 365 patients, males were the majority (213, 58.4%), mean age was 60.5 years, and 53 (14.5%) patients were HIV-co-infected. Liver cirrhosis was observed in 251 (68.8%) subjects, and the most represented genotypes were 1b (n = 168, 46%) and 3 (n = 59, 16.2%). DAA was discontinued a median of 1 (IQR 1-4) weeks before the predefined EOT, with 164 (44.9%) patients stopping DAAs at least 2 weeks before the planned schedule. In patients with F0-F3 liver fibrosis, lower rates of SVR12 were observed in patients treated for <4 weeks: 50% (n = 2/4) vs. 99.1% (n = 109/110) for ≥4 weeks, p = 0.003. In patients with liver cirrhosis, lower rates of SVR12 were observed in patients treated <8 weeks: 83.3% (n = 25/30) vs. 94.6% (n = 209/221) for ≥8 weeks, p = 0.038. Despite premature discontinuation of DAA, high SVR12 rates were observed in a real-life setting for treatment lasting at least 4 weeks in patients with liver fibrosis F0-F3 and 8 weeks in those with liver cirrhosis. On this basis, feasibility of reducing DAA treatment duration should be explored in randomized clinical trials.

Covid-19 and gender: lower rate but same mortality of severe disease in women-an observational study.

BACKGROUND: Gender-related factors might affect vulnerability to Covid-19. The aim of this study was to describe the role of gender on clinical features and 28-day mortality in Covid-19 patients. METHODS: Observational study of Covid-19 patients hospitalized in Bergamo, Italy, during the first three weeks of the outbreak. Medical records, clinical, radiological and laboratory findings upon admission and treatment have been collected. Primary outcome was 28-day mortality since hospitalization. RESULTS: 431 consecutive adult patients were admitted. Female patients were 119 (27.6%) with a mean age of 67.0 ± 14.5 years (vs 67.8 ± 12.5 for males, p = 0.54). Previous history of myocardial infarction, vasculopathy and former smoking habits were more common for males. At the time of admission PaO2/FiO2 was similar between men and women (228 [IQR, 134-273] vs 238 mmHg [150-281], p = 0.28). Continuous Positive Airway Pressure (CPAP) assistance was needed in the first 24 h more frequently in male patients (25.7% vs 13.0%; p = 0.006). Overall 28-day mortality was 26.1% in women and 38.1% in men (p = 0.018). Gender did not result an independent predictor of death once the parameters related to disease severity at presentation were included in the multivariable analysis (p = 0.898). Accordingly, the Kaplan-Meier survival analysis in female and male patients requiring CPAP or non-invasive ventilation in the first 24 h did not find a significant difference (p = 0.687). CONCLUSION: Hospitalized women are less likely to die from Covid-19; however, once severe disease occurs, the risk of dying is similar to men. Further studies are needed to better investigate the role of gender in clinical course and outcome of Covid-19.

Liver transplantation in hepatocellular carcinoma after tumour downstaging (XXL): a randomised, controlled, phase 2b/3 trial.

BACKGROUND: Indications for liver transplantation for hepatocellular carcinoma are evolving and so-called expanded criteria remain debated. Locoregional therapies are able to downstage hepatocellular carcinoma from beyond to within the Milan criteria. We aimed to investigate the efficacy of liver transplantation after successful hepatocellular carcinoma downstaging. METHODS: We did an open-label, multicentre, randomised, controlled trial designed in two phases, 2b and 3, at nine Italian tertiary care and transplantation centres. Patients aged 18-65 years with hepatocellular carcinoma beyond the Milan criteria, absence of macrovascular invasion or extrahepatic spread, 5-year estimated post-transplantation survival of at least 50%, and good liver function (Child-Pugh A-B7) were recruited and underwent tumour downstaging with locoregional, surgical, or systemic therapies according to multidisciplinary decision. After an observation period of 3 months, during which sorafenib was allowed, patients with partial or complete responses according to modified Response Evaluation Criteria in Solid Tumors were randomly assigned (1:1) by an interactive web-response system to liver transplantation or non-transplantation therapies (control group). A block randomisation (block size of 2), stratified by centre and compliance to sorafenib treatment, was applied. Liver transplantation was done with whole or split organs procured from brain-dead donors. The control group received sequences of locoregional and systemic treatment at the time of demonstrated tumour progression. The primary outcomes were 5-year tumour event-free survival for phase 2b and overall survival for phase 3. Analyses were by intention to treat. Organ allocation policy changed during the course of the study and restricted patient accrual to 4 years. This trial is registered with ClinicalTrials.gov, NCT01387503. FINDINGS: Between March 1, 2011, and March 31, 2015, 74 patients were enrolled. Median duration of downstaging was 6 months (IQR 4-11). 29 patients dropped out before randomisation and 45 were randomly assigned: 23 to the transplantation group versus 22 to the control group. At data cutoff on July 31, 2019, median follow-up was 71 months (IQR 60-85). 5-year tumour event-free survival was 76·8% (95% CI 60·8-96·9) in the transplantation group versus 18·3% (7·1-47·0) in the control group (hazard ratio [HR] 0·20, 95% CI 0·07-0·57; p=0·003). 5-year overall survival was 77·5% (95% CI 61·9-97·1) in the transplantation group versus 31·2% (16·6-58·5) in the control group (HR 0·32, 95% CI 0·11-0·92; p=0·035). The most common registered grade 3-4 serious adverse events were hepatitis C virus recurrence (three [13%] of 23 patients) and acute transplant rejection (two [9%]) in the transplantation group, and post-embolisation syndrome (two [9%] of 22 patients) in the control group. Treatment-related deaths occurred in four patients: two (8%) of 23 patients in the transplantation group (myocardial infarction and multi-organ failure) versus two (9%) of 22 patients in the control group (liver decompensation). INTERPRETATION: Although results must be interpreted with caution owing to the early closing of the trial, after effective and sustained downstaging of eligible hepatocellular carcinomas beyond the Milan criteria, liver transplantation improved tumour event-free survival and overall survival compared with non-transplantation therapies Post-downstaging tumour response could contribute to the expansion of hepatocellular carcinoma transplantation criteria.

High rates of 30-day mortality in patients with cirrhosis and COVID-19.

BACKGROUND & AIMS: Coronavirus disease 2019 (COVID-19) poses a major health threat to healthy individuals and those with comorbidities, but its impact on patients with cirrhosis is currently unknown. Herein, we aimed to evaluate the impact of COVID-19 on the clinical outcome of patients with cirrhosis. METHODS: In this multicentre retrospective study, patients with cirrhosis and a confirmed severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection were enrolled between 1st and 31th March 2020. Clinical and biochemical data at diagnosis of COVID-19 and at the last outpatient visit were obtained through review of medical records. RESULTS: Fifty patients with cirrhosis and confirmed SARS-CoV-2 infection were enrolled (age 67 years, 70% men, 38% virus-related, 52% previously compensated cirrhosis). At diagnosis, 64% of patients presented fever, 42% shortness of breath/polypnea, 22% encephalopathy, 96% needed hospitalization or a prolonged stay if already in hospital. Respiratory support was necessary in 71%, 52% received antivirals, 80% heparin. Serum albumin significantly decreased, while bilirubin, creatinine and prothrombin time significantly increased at COVID-19 diagnosis compared to last available data. The proportion of patients with a model for end-stage liver disease (MELD) score ≥15 increased from 13% to 26% (p = 0.037), acute-on-chronic liver failure and de novo acute liver injury occurred in 14 (28%) and 10 patients, respectively. Seventeen patients died after a median of 10 (4-13) days from COVID-19 diagnosis, with a 30-day-mortality rate of 34%. The severity of lung and liver (according to CLIF-C, CLIF-OF and MELD scores) diseases independently predicted mortality. In patients with cirrhosis, mortality was significantly higher in those with COVID-19 than in those hospitalized for bacterial infections. CONCLUSION: COVID-19 is associated with liver function deterioration and elevated mortality in patients with cirrhosis. LAY SUMMARY: Coronavirus disease 2019 (COVID-19) poses a major health threat to healthy individuals and those with comorbidities. Herein, we assessed its impact on patients with cirrhosis. Infection with COVID-19 was associated with liver function deterioration and elevated mortality in patients with cirrhosis.

Outcomes of Liver Transplant for Adults With Wilson's Disease.

Wilson's disease (WD) is a rare genetic disorder with protean manifestations. Even if liver transplantation (LT) could represent an effective therapeutic option for patients with end-stage liver disease, it has remained controversial in the presence of neuropsychiatric involvement. This study aimed to examine the frequency of adult LT for WD in Italy, focusing on the disease phenotype at the time of LT. A retrospective, observational, multicenter study was conducted across Italy exploring the frequency and characteristics of adults transplanted for WD between 2006 and 2016. A total of 29 adult WD patients underwent LT during the study period at 11 Italian LT centers (accounting for 0.4% of all LTs performed), and 27 of them were considered in this analysis (male/female, n = 9/18; age at LT, 29 years [19-60 years]; median Model for End-Stage Liver Disease score at LT, 27 [6-49]). Isolated hepatic phenotype was the indication for LT in 17 (63%) patients, whereas 2 (7%) patients underwent LT for neurological impairment on compensated liver disease. Overall 1- and 5-year patient survival was excellent (88% and 83%, respectively). Neuropsychiatric symptoms early after LT completely recovered in only a few patients. In conclusion, WD remains an uncommon, unusual indication for LT in Italy, displaying good post-LT graft and patient survival. Because isolated neuropsychiatric involvement represents a rare indication to LT, more data are needed to properly assess the value of LT for WD in this subset of patients.

Health related quality of life in chronic liver diseases.

BACKGROUND & AIMS: The impact of chronic liver diseases (CLDs) on health-related quality of life (HRQoL) is relevant to understand the burden of these conditions and inform decision-making processes related to their care. Studies simultaneously comparing the HRQoL of patients affected by the major CLDs to that of the general population are still lacking and are the subject of this study. METHODS: Using the EQ-5D-3L questionnaire, we analysed and compared HRQoL data from 2962 Italian patients affected by CLDs and forming a representative sample of the general Italian population (6800 individuals). Exploratory analyses were conducted to investigate the effects of each CLD on HRQoL, using the general population as reference and adjusting for possible confounders. RESULTS: Patients with CLDs (HBV, HCV, PSC, PBC, AIH, NAFLD/NASH) in the chronic hepatitis stage and with compensated cirrhosis (CC) showed HRQoL similar to the general population. However, AIH were more likely to report problems in self-care and lower EQ-5D VAS score, while NAFLD/NASH and HCV showed an increased risk of anxiety/depression. On the other hand, with progression to more advanced stages of liver disease (DC or HCC), HRQoL decreased significantly with higher risk of reporting problems in the physical domains, and significant reductions in the VAS and utility index scores. CONCLUSIONS: Different subtypes of CLD affected different QoL domains. This study therefore provides a real estimate of the impact of CLDs on patients' HRQoL, and represents a much needed tool to inform decision-making while assessing the effectiveness and cost-effectiveness of the care of these patients.

Global real-world evidence of sofosbuvir/velpatasvir as simple, effective HCV treatment: Analysis of 5552 patients from 12 cohorts.

BACKGROUND AND AIMS: Achieving sustained virological response (SVR; cure) in hepatitis C patients using a simple regimen is key to making elimination by 2030 possible. In the largest real-world analysis to date, the effectiveness of pangenotypic, panfibrotic, single-tablet, sofosbuvir/velpatasvir (SOF/VEL) once-daily for 12 weeks was assessed in 12 clinical real-world cohorts from various geographical areas, settings and treatment practices. Factors affecting risk of not achieving SVR were assessed. METHODS: Adults treated with SOF/VEL 400/100 mg, without ribavirin, were included. All HCV patients reaching Week 12 or 24 post-treatment were assessed for SVR12/24. Factors associated with not achieving SVR12/24 for virological reasons were evaluated using logistic regression analysis. RESULTS: Overall, 5552 patients were included: 13.3% treatment-experienced; 20.7% compensated cirrhotic; 30.2% genotype 1; 29.5% genotype 2; 32.9% genotype 3; 4.7% genotype 4; 3.7% HIV coinfection; 13.4% current/former intravenous drug use. Of the 5196 patients evaluated for effectiveness, 98.9% achieved SVR12/24. High SVR12/24 rates occurred in all genotypes including genotype 3 (98.3%; 1649/1677) and in those with compensated cirrhosis (97.9; 1055/1078). Only 55 patients did not achieve SVR12/24 due to a virological reason; the only factor statistically significantly associated with an increased risk of not achieving SVR12/24 was compensated cirrhosis (P = .002). Overall, 6% (332/5552) of patients did not achieve SVR12/24 for non-virological reasons (67% lost to follow-up; 26.5% early treatment discontinuation). CONCLUSIONS: In this large cohort, representative of clinical practice, a simple 12-week regimen of SOF/VEL without ribavirin resulted in high SVR12/24 rates in diverse patient populations, even among those with compensated cirrhosis.

Clinical outcome indicators in chronic hepatitis B and C: A primer for value-based medicine in hepatology.

BACKGROUND & AIMS: Chronic liver diseases (CLDs) are major health problems that require complex and costly treatments. Liver-specific clinical outcome indicators (COIs) able to assist both clinicians and administrators in improving the value of care are presently lacking. The Value-Based Medicine in Hepatology (VBMH) study aims to fill this gap, devising and testing a set of COIs for CLD, that could be easily collected during clinical practice. Here we report the COIs generated and recorded for patients with HBV or HCV infection at different stages of the disease. METHODS/RESULTS: In the first phase of VBMH study, COIs were identified, based on current international guidelines and literature, using a modified Delphi method and a RAND 9-point appropriateness scale. In the second phase, COIs were tested in an observational, longitudinal, prospective, multicentre study based in Lombardy, Italy. Eighteen COIs were identified for HBV and HCV patients. Patients with CLD secondary to HBV (547) or HCV (1391) were enrolled over an 18-month period and followed for a median of 4 years. The estimation of the proposed COIs was feasible in the real-word clinical practice and COI values compared well with literature data. Further, the COIs were able to capture the impact of new effective treatments like direct-acting antivirals (DAAs) in the clinical practice. CONCLUSIONS: The COIs efficiently measured clinical outcomes at different stages of CLDs. While specific clinical practice settings and related healthcare systems may modify their implementation, these indicators will represent an important component of the tools for a value-based approach in hepatology and will positively affect care delivery.
