Evaluation of the effects of pre-exposure treatment with hydroxychloroquine on the risk of COVID-19 infection and on the efficacy of anti-COVID-19 vaccination during lupus or Gougerot-Sjögren's disease: Prepcov multicentre trial.

Objectives: Some patients with SLE or Gougerot-Sjögren's disease (GSD) receive long-term treatment with hydroxychloroquine (HCQ), sometimes combined with immunosuppressive therapy (IS). This study sought to assess whether long-term HCQ therapy that had been initiated long before the COVID-19 pandemic had a protective or adverse effect on COVID-19 risk, severity of infection or immunity protection.

Methods: This prospective multicentre study included 547 patients with SLE, GSD, autoimmune hepatitis, primary biliary cholangitis or cured viral hepatitis C divided into four groups according to HCQ (+/-) and IS (+/-) intake prior to the pandemic: HCQ+IS+ (n=112), HCQ+IS- (n=121), HCQ-IS+ (n=115) and HCQ-IS- (n=199).

Non-invasive assessment of severe liver fibrosis in patients with Fontan-associated liver disease: The VALDIG-EASL FONLIVER cohort.

Background & Aims: Fontan-type surgery is a palliative procedure for congenital heart disease with univentricular physiology that may, in the long term, lead to advanced chronic liver disease. Herein, we assessed the accuracy of conventional non-invasive models for assessing liver fibrosis in the context of Fontan circulation and developed a new risk score employing non-invasive tools.

Methods: A prospective, cross-sectional, observational study was conducted across five European centers and encompassing all consecutive adult patients with Fontan circulation, liver biopsy and non-invasive tests (e.

Association between direct acting agents used for chronic hepatitis C virus infection and the occurrence of acute leukaemia - A disproportionality analysis.

Background And Aims: A recent single-center study reported a significant increase in acute myeloid leukaemia (AML) cases, including mixed-phenotype acute leukaemia (MPAL), after exposure to direct acting agents (DAA). We investigated whether DAA use increased the risk of AML in patients with chronic hepatitis C virus (HCV) infection.

Methods: We conducted a disproportionality analysis of the WHO Pharmacovigilance database Vigibase up to 2020.

Utility of a score-based approach to liver assessment in heart transplant candidates.

Background: While abnormalities of liver function and imaging are common in patients with end-stage heart failure, advanced fibrosis is uncommon. Liver biopsy (LB) is used to identify advanced fibrosis in heart transplant (HT) candidates but can delay or limit access to definitive therapies and cause complications. We sought to develop and determine the utility of a clinical risk score for advanced fibrosis in HT candidates.

Clinical and genetic definition of serum bilirubin levels for the diagnosis of Gilbert syndrome and hypobilirubinemia.

Background And Aims: Gilbert syndrome (GS) is genotypically predetermined by UGT1A1*28 homozygosity in Europeans and is phenotypically defined by hyperbilirubinemia using total bilirubin (TB) cutoff ≥1mg/dL (17 μmol/L). The prevalence of illnesses associated with GS and hypobilirubinemia has never been studied prospectively. As TB varies with UGT1A1*28 genotyping, sex, and age, we propose stratified definitions of TB reference intervals and report the prevalence of illnesses and adjusted 15 years survival.

Economic Impact of European Liver and Intestine Transplantation Association (ELITA) Recommendations for Hepatitis B Prophylaxis After Liver Transplantation.

The European Liver and Intestine Transplant Association, ELITA, promoted a Consensus Conference involving 20 experts across the world which generated updated guidelines on HBV prophylaxis in liver transplant candidates and recipients. This study explores the economic impact associated with the implementation of the new ELITA guidelines. To this aim, a condition-specific cohort simulation model has been developed to compare new and historical prophylaxis, including only pharmaceutical cost and using the European perspective.

Patients Treated for HCV Infection and Listed for Liver Transplantation in a French Multicenter Study: What Happens at Five Years?

Background: Direct-acting antiviral (DAA) agents for the treatment of hepatitis C virus (HCV) infection have been proven safe and effective in cirrhotic patients awaiting liver transplantation (LT). However, in the long term, data remain minimal regarding the clinical impact of viral eradication on patients listed for decompensated cirrhosis or hepatocellular carcinoma (HCC). We aimed to elucidate the clinical outcomes of patients regarding delisting and the evolution of HCC during the long-term follow-up.

Diagnosis and management of hepatic encephalopathy: The French recommendations.

Hepatic encephalopathy (HE) is a frequent and severe complication of liver disease with poor patient outcomes. However, it is a poorly understood complication, with no consensus for diagnosis. Therefore, HE is often underdiagnosed.

HCV eradication does not protect from fibrosis progression in patients with fibrosing cholestatic hepatitis after liver transplantation.

Introduction: Hepatitis C virus (HCV) may recur after liver transplantation (LT) in the severe form of fibrosing cholestatic hepatitis (FCH). The prognosis dramatically improved by the use of direct acting antivirals (DAAs). The aim of the present study was to describe the change in histological features of FCH after virological eradication.

Acute myeloid leukaemia following direct acting antiviral drugs in HCV-infected patients: A 10 years' retrospective single-center study.

Background: After several cases of peculiar hematological malignancies following introduction of new oral anti-hepatitis C virus (HCV) treatments in our recent practice, we aimed to systematically identify all cases of hematological malignancies (HM) in patients with chronic HCV infection and to compare them according to the prescription of oral anti-HCV Direct Acting Antivirals (DAA) treatment or not.

Material/methods: In this single-center retrospective observational study, we included all patients with confirmed HM and chronic HCV infection managed between 2010 and 2019 in the Pitié-Salpêtrière hospital, Paris. Non-inclusion criteria were a benign hematological disorder, an HM preceding chronic HCV infection and HCV acute infection.

"De novo" cholangiocarcinoma 20 years after liver transplantation for primary sclerosing cholangitis: Lifelong screening needed!

We report a rare and very late case of de novo cholangiocarcinoma in a patient transplanted for primary sclerosing cholangitis. An exhaustive analysis of the literature and of our case highlight the very poor prognosis of this type of tumor due to the delay in diagnosis and the potential value of a six-monthly MRI surveillance as soon as cholangitis recurs, but also in the presence of chronic digestive inflammation, whatever the mechanism.

2020 position statement and recommendations of the European Liver and Intestine Transplantation Association (ELITA): management of hepatitis B virus-related infection before and after liver transplantation.

Background: Prophylaxis of HBV recurrence is critical after liver transplantation in HBV patients. Despite new prophylactic schemes, most European LT centres persist on a conservative approach combining hepatitis B immunoglobulin (HBIG) and nucleos(t)ides analogues (NA).

Aim: This setting prompted the European Liver Intestine Transplantation Association (ELITA) to look for a consensus on the prevention of HBV recurrence.

Risk factors of de novo malignancies after liver transplantation: a French national study on 11004 adult patients.

Background: After liver transplantation (LT),de novo malignancies are one of the leading causes of late mortality. The aim of the present retrospective study was to identify the risk factors of de novo malignancies in a large cohort of LT recipients in France, using Fine and Gray competing risks regression analysis.

Methods: The study population consisted in 11004 adults transplanted between 2000 and 2013, who had no history of pre-transplant malignancy, except primary liver tumor.

From congestive hepatopathy to hepatocellular carcinoma, how can we improve patient management?

Heart failure and liver disease often coexist because of systemic disorders and diseases that affect both organs as well as complex cardio-hepatic interactions. Heart failure can cause acute or chronic liver injury due to ischaemia and passive venous congestion, respectively. Congestive hepatopathy is frequently observed in patients with congenital heart disease and after the Fontan procedure, but also in older patients with chronic heart failure.

Clinical validation of the FLIP algorithm and the SAF score in patients with non-alcoholic fatty liver disease.

Background & Aims: Histological classifications used to diagnose/stage non-alcoholic fatty liver disease (NAFLD) are based on morphology, with undetermined clinical correlates and relevance. We assessed the clinical relevance of the fatty liver inhibition of progression (FLIP) algorithm and the steatosis, activity, and fibrosis (SAF) scoring system.

Methods: One hundred and forty consecutive patients with suspected NAFLD and a separate validation cohort of 78 patients enrolled in a therapeutic trial, all with central reading of liver biopsy, were included.

Ribavirin for Hepatitis E Virus Infection After Organ Transplantation: A Large European Retrospective Multicenter Study.

Background: Ribavirin is currently recommended for treating chronic hepatitis E virus (HEV) infection. This retrospective European multicenter study aimed to assess the sustained virological response (SVR) in a large cohort of solid organ transplant (SOT) recipients with chronic HEV infection treated with ribavirin monotherapy (N = 255), to identify the predictive factors for SVR, and to evaluate the impact of HEV RNA mutations on virological response.

Methods: Data from 255 SOT recipients with chronic HEV infection from 30 European centers were analyzed.

Combined heart and liver transplantation: State of knowledge and outlooks.

Various types of liver impairment have been described in patients with end-stage heart failure who are awaiting heart transplantation. The liver impairment may be severe, characterized by a high model for end-stage liver disease (MELD) Score and/or the presence of ascites, both of which are associated with a high risk of failure after single heart transplantation. A liver function assessment is therefore necessary before registration on the heart transplant list, moreover in case of long-developing heart failure, such as with congenital heart disease or in the presence of risk factors for chronic liver disease including excessive alcohol consumption, metabolic syndrome or chronic viral hepatitis B or C.

LCR1 and LCR2, two multi-analyte blood tests to assess liver cancer risk in patients without or with cirrhosis.

Background: No blood test has been shown to be effective in the prediction of primary liver cancer in patients without cirrhosis.

Aim: To construct and internally validate two sequential tests for early prediction of liver cancer. These tests enable an algorithm which could improve the performance of the standard surveillance protocol recommended (imaging with or without AFP), limited to patients with cirrhosis.

Long-term prognostic value of the FibroTest in patients with non-alcoholic fatty liver disease, compared to chronic hepatitis C, B, and alcoholic liver disease.

Background: Although the FibroTest has been validated as a biomarker to determine the stage of fibrosis in non-alcoholic fatty liver disease (NAFLD) with results similar to those in chronic hepatitis C (CHC), B (CHB), and alcoholic liver disease (ALD), it has not yet been confirmed for the prediction of liver-related death.

Aim: To validate the 10-year prognostic value of FibroTest in NAFLD for the prediction of liver-related death.

Method: Patients in the prospective FibroFrance cohort who underwent a FibroTest between 1997 and 2012 were pre-included.

Net emergence of substitutions at position 28 in NS5A of hepatitis C virus genotype 4 in patients failing direct-acting antivirals detected by next-generation sequencing.

More data on resistance of HCV genotype (GT) 3 and 4 to direct-acting antivirals (DAAs) are still needed. Here we investigated the presence of resistance-associated substitutions (RASs) pre- and post-treatment and their emergence under DAAs in HCV GT3- and GT4-infected patients failing DAA regimens by next-generation sequencing (NGS). Sanger sequencing and NGS were performed on NS5B and NS5A in plasma samples prior to and post treatment of 13 patients.

Evolution of platelet functions in cirrhotic patients undergoing liver transplantation: A prospective exploration over a month.

This prospective observational study was designed to analyze platelet functions across time in 50 patients scheduled for liver transplantation (LT) secondary to decompensated cirrhosis or hepatocellular carcinoma. Platelet functions were assessed before LT (pre-LT), one week (D7) and 1 month (D28) after LT. Platelet count significantly increased from pre-LT time to day 28 as well as circulating CD34+hematopoietic stem cells.

Longterm Risk of Solid Organ De Novo Malignancies After Liver Transplantation: A French National Study on 11,226 Patients.

De novo malignancies are one of the major late complications and causes of death after liver transplantation (LT). Using extensive data from the French national Agence de la Biomédecine database, the present study aimed to quantify the risk of solid organ de novo malignancies (excluding nonmelanoma skin cancers) after LT. The incidence of de novo malignancies among all LT patients between 1993 and 2012 was compared with that of the French population, standardized on age, sex, and calendar period (standardized incidence ratio; SIR).
