Abstract: Abstract Background In HCV-infected patients with advanced liver disease, the direct antiviral agents-associated clinical benefits remain debated. We compared the clinical outcome of patients with a previous history of decompensated cirrhosis following treatment or not with direct antiviral agents from the French ANRS CO22 HEPATHER cohort. Methods We identified HCV patients who had experienced an episode of decompensated cirrhosis. Study outcomes were all-cause mortality, liver-related or non-liver-related deaths, hepatocellular carcinoma, liver transplantation. Secondary study outcomes were sustained virological response and its clinical benefits. Results 559 patients met the identification criteria, of which 483 received direct antiviral agents and 76 remained untreated after inclusion in the cohort. The median follow-up time was 39.7 (IQR: 22.7–51) months. After adjustment for multivariate analysis, exposure to direct antiviral agents was associated with a decrease in all-cause mortality (HR 0.45, 95% CI 0.24–0.84, p = 0.01) and non-liver-related death (HR 0.26, 95% CI 0.08–0.82, p = 0.02), and was not associated with liver-related death, decrease in hepatocellular carcinoma and need for liver transplantation. The sustained virological response was 88%. According to adjusted multivariable analysis, sustained virological response achievement was associated with a decrease in all-cause mortality (HR 0.29, 95% CI 0.15–0.54, p

Abstract: Abstract Background Although real-life results of sofosbuvir/simeprevir have been extensively reported from the United States, data from other geographical areas are limited. In the French observational cohort, ANRS CO22 HEPATHER, 9432 patients were given the new oral antivirals from December 2013 to June 30, 2018. We report the results of sofosbuvir/simeprevir in genotypes 1- and 4-infected patients. Methods Demographics and history of liver disease were collected at entry in the cohort. Clinical, adverse events, and virological data were collected throughout treatment and post-treatment follow-up. The choice of treatment duration or addition of ribavirin was left up to the physician. Results Five hundred ninety-nine HCV (467 genotype 1 and 132 genotype 4) mono-infected, naïve for all oral-DAAs regimen patients were given sofosbuvir/simeprevir with (n = 63) or without ribavirin (n = 536) for 12 or 24 weeks; 56% had cirrhosis (4% decompensated) and 71% had prior treatment failure to interferon-based regimen. 7 patients (1.16%) were lost to follow-up. The overall SVR12 rate was 92.6%. The SVR12 was 90% in GT1a, 94.2% in GT1b and 91.6% in GT4 with no significant difference for genotype, treatment duration or ribavirin addition. Severity of liver disease was not associated with a lower SVR12 rate on multivariate analysis but was associated with a higher rate of severe side effects. Early treatment discontinuations were rare; no new safety signals were reported. Conclusion In this real life, observational, prospective cohort study, the 12-week sofosbuvir/simeprevir+/−ribavirin combination appears to be efficient and safe.

Abstract: Patients with primary sclerosing cholangitis (PSC) develop progressive liver fibrosis and end-stage liver disease. Non-invasive and widely available parameters are urgently needed to assess disease stage and the risk of clinical progression. Transient elastography (TE) has been reported to predict fibrosis stage and disease progression. However, these results have not been confirmed in an independent cohort and comparison of TE measurement to other non-invasive means is missing.In a retrospective study we collected data from consecutive PSC patients receiving TE measurements from 2006 to 2014 (n = 139). Data from 62 patients who also underwent a liver biopsy were used to assess the performance of TE and spleen length (SL) measurement for the staging of liver fibrosis. Follow-up data from this cohort (n = 130, Hamburg) and another independent cohort (n = 80, Paris) was used to compare TE and SL as predictors of clinical outcome applying Harrel's C calculations.TE measurement had a very good performance for the diagnosis and exclusion of higher fibrosis stages (≥F3: AUROC 0.95) and an excellent performance for the diagnosis and exclusion of cirrhosis (F4 vs. < F4: AUROC 0.98). Single-point TE measurement had very similar predictive power for patient outcome as previously published. In a combined cohort of PSC patients (n = 210), SL measurements had a similar performance as TE for the prediction of patient outcome (5 x cross-validated Harrel's C 0.76 and 0.72 for SL and TE, respectively).Baseline TE measurement has an excellent performance to diagnose higher fibrosis stages in PSC. Baseline measurements of SL and TE have similar usefulness as predictive markers for disease progression in patients with PSC.

Abstract: Background & Aims: In France, bulevirtide (BLV) became available in September 2019 through an early access program to treat patients with HDV. The aim of this analysis was to evaluate the efficacy and safety of BLV in patients with HIV and HDV coinfection. Methods: Patients received BLV 2 mg ± pegylated interferon-α (pegIFNα) according to the physician’s decision. The primary endpoint (per-protocol analysis) was the virological response rate at Week 48, defined as the proportion of patients with undetectable serum HDV RNA or a HDV RNA decline >2 log10 IU/ml from baseline. Results: The characteristics of the 38 patients were as follows: 28 male, mean age 47.7 years, and mean baseline HDV RNA viral load 5.7 ± 1.2 log10 IU/ml. Median HIV viral load and mean CD4 count were 32 (30–65) copies/ml and 566 ± 307/mm3, respectively. Eight patients stopped treatment before Week 48. At Week 48, 10 of 19 patients (52.6%) in the 2 mg BLV group and five of seven patients (71.4%) in the 2 mg BLV + pegIFNɑ group had reached virological response (no HDV RNA available in four patients). At Week 48, seven of 19 patients in the 2 mg BLV group and three of six patients in the 2 mg BLV + pegIFNɑ group had a combined response (virological response and normal alanine aminotransferase level). Conclusions: Adults living with HIV coinfected with HDV can be treated by BLV with a virological response in more than 50% of patients. The combination of BLV and pegIFNɑ showed a strong virological response. Impact and implications: Bulevirtide is the only EMA-approved drug for HDV treatment, and we showed that it can be used in adults living with HIV, with an overall good tolerability. Bulevirtide induces a virological response in more than 50% of patients, suggesting that bulevirtide should be considered as a first-line therapy in this specific population. Bulevirtide in combination with pegIFNα could be used in patients without pegIFNα contraindication. No specific drug–drug interaction is reported.

Abstract: Background & Aims: Gallbladder enlargement is common in patients with primary sclerosing cholangitis (PSC). The gallbladder may confer hepatoprotection against bile acid overload, through the sequestration and cholecystohepatic shunt of bile acids. The aim of this study was to assess the potential impact of the gallbladder on disease features and bile acid homeostasis in PSC. Methods: Patients with PSC from a single tertiary center who underwent liver MRI with three-dimensional cholangiography and concomitant analyses of serum bile acids were included. Gallbladder volume was measured by MRI and a cut-off of 50 ml was used to define gallbladder enlargement. Bile acid profiles and PSC severity, as assessed by blood tests and MRI features, were compared among patients according to gallbladder size (enlarged vs. normal-sized) or presence (removed vs. conserved). The impact of cholecystectomy was also assessed in the Abcb4 knockout mouse model of PSC. Results: Sixty-one patients with PSC, all treated with ursodeoxycholic acid (UDCA), were included. The gallbladder was enlarged in 30 patients, whereas 11 patients had been previously cholecystectomized. Patients with enlarged gallbladders had significantly lower alkaline phosphatase, a lower tauro-vs. glycoconjugate ratio and a higher UDCA vs. total bile acid ratio compared to those with normal-sized gallbladders. In addition, gallbladder volume negatively correlated with the hydrophobicity index of bile acids. Cholecystectomized patients displayed significantly higher aspartate aminotransferase and more severe bile duct strictures and dilatations compared to those with conserved gallbladder. In the Abcb4 knockout mice, cholecystectomy caused an increase in hepatic bile acid content and in circulating secondary bile acids, and an aggravation in cholangitis, inflammation and liver fibrosis. Conclusion: Altogether, our findings indicate that the gallbladder fulfills protective functions in PSC. Impact and implications: In patients with primary sclerosing cholangitis (PSC), gallbladder status impacts on bile acid homeostasis and disease features. We found evidence of lessened bile acid toxicity in patients with PSC and enlarged gallbladders and of increased disease severity in those who were previously cholecystectomized. In the Abcb4 knockout mouse model of PSC, cholecystectomy causes an aggravation of cholangitis and liver fibrosis. Overall, our results suggest that the gallbladder plays a protective role in PSC.

Subjects: MRCP+, Prognosis, Magnetic resonance imaging, Liver stiffness, Cholestasis, Diseases of the digestive system. Gastroenterology, RC799-869
Abstract: Background & Aims: People with primary sclerosing cholangitis (PSC) have a variable and often progressive disease course that is associated with biliary and parenchymal changes. These changes are typically assessed by magnetic resonance imaging (MRI), including qualitative assessment of magnetic resonance cholangiopancreatography (MRCP). Our aim was to study the association of novel objective quantitative MRCP metrics with prognostic scores and patient outcomes. Methods: We performed a retrospective study including 77 individuals with large-duct PSC with baseline MRCP images, which were postprocessed to obtain quantitative measures of bile ducts using MRCP+™. The participants’ ANALI scores, liver stiffness by vibration-controlled transient elastography, and biochemical indices were collected at baseline. Adverse outcome-free survival was measured as the absence of decompensated cirrhosis, liver transplantation (LT), or liver-related death over a 12-year period. The prognostic value of MRCP+-derived metrics was assessed by Cox regression modelling. Results: During a total of 386 patients-years, 16 cases of decompensation, 2 LTs, and 5 liver-related deaths were recorded. At baseline, around 50% of the patients were classified as being at risk of developing disease complications. MRCP+ metrics, particularly those describing the severity of bile duct dilatations, were correlated with all prognostic factors. Univariate analysis showed that MRCP+ metrics representing duct diameter, dilatations, and the percentage of ducts with strictures and/or dilatations were associated with survival. In a multivariable-adjusted analysis, the median duct diameter was significantly associated with survival (hazard ratio 10.9, 95% CI 1.3–90.3). Conclusions: MRCP+ metrics in people with PSC correlate with biochemical, elastographic, and radiological prognostic scores and are predictive of adverse outcome-free survival. Lay summary: In this study, we assessed in people with primary sclerosing cholangitis (PSC) the association of novel objective quantitative MRCP metrics automatically provided by a software tool (MRCP+) with prognostic scores and patient outcomes. We observed that MRCP+ metrics in people with PSC correlate with biochemical, elastographic, and radiological prognostic scores and are predictive of adverse outcome-free survival.

Abstract: Background & Aims: In this study we aimed to analyse the impact of the aetiology of cirrhosis on the incidence, characteristics and prognosis of hepatocellular carcinoma (HCC) diagnosed during a surveillance program. Methods: Individual data from a randomized trial and 2 prospective cohorts of patients with compensated histologically proven cirrhosis recruited between 2000 and 2016 were pooled. The influence of cirrhosis aetiology on survival after HCC detection was assessed using multivariable regression models. Results: Among 3,533 patients (1,926 virus [VIR], 1,167 alcohol [ALC], 440 combined [MIX]), 431 were diagnosed with HCC after a median follow-up of 57.1 months. The 5-year HCC incidence was lowest in ALC (VIR 12.6%, ALC 9.1%, MIX 14.3%, p = 0.04). At the time of diagnosis, tumour burden and Child-Pugh score were comparable across aetiology groups, but early BCLC stages (0/A) were significantly less frequent in ALC (VIR 80%, ALC 37%, MIX 72%) as a result of worse ECOG performance status. However, similar access to first-line curative HCC treatment was reported across aetiology groups (p = 0.68). Median survival after HCC diagnosis was significantly reduced in ALC (VIR 39, ALC 21, MIX 34 months, p = 0.02). However, when adjusting for tumour size, ECOG and Child-Pugh score, the aetiology of the underlying cirrhosis no longer had a significant impact. Conclusion: Compared to patients with virus-related cirrhosis, patients with alcohol-related compensated cirrhosis enrolled in a surveillance program have: i) the lowest 5-year HCC incidence; ii) worse overall prognosis, mostly driven by a poor general condition, despite similar access to first-line curative treatment. Lay summary: It has been suggested that early detection of hepatocellular carcinoma (HCC) may be futile in patients with alcohol-related cirrhosis. By comparing outcomes in more than 3,000 patients with compensated cirrhosis included in surveillance programs, this study suggests that HCC surveillance enables early diagnosis in most patients with alcohol-related cirrhosis despite a higher competing risk of death in these patients. We also report similar access to first-line curative HCC treatment in these patients compared to those with viral cirrhosis, despite higher rates of comorbidities and impaired liver function. Following HCC detection, the later parameters were major drivers of death irrespective of the cause of cirrhosis. Registration: CHC2000 (NCT00190385) and CIRRAL (NCT01213927) cohorts were registered at ClinicalTrials.gov and the full protocols are available at the following links (https://clinicaltrials.gov/ct2/show/NCT00190385) and https://clinicaltrials.gov/ct2/show/NCT01213927, respectively).

Author: Christophe Corpechot, Raoul Poupon, and Olivier Chazouillères
Subjects: Diseases of the digestive system. Gastroenterology, RC799-869
Abstract: Summary: Primary biliary cholangitis (PBC) is an autoimmune, cholestatic, chronic liver disease that ultimately progresses towards cirrhosis and liver failure if untreated. While ursodeoxycholic acid has been established as standard of care for PBC in the last few decades, significant advances in second-line treatment options have recently been made and new therapeutic developments are currently under evaluation. The purpose of this article is to provide the clinician with an overview of the current treatment options and future opportunities for patients with PBC.

Abstract: Background & Aims: Low-phospholipid-associated cholelithiasis (LPAC) syndrome, a rare genetic form of intrahepatic cholelithiasis in adults, is still poorly understood. We report the results of the largest-ever case-control study of patients with LPAC syndrome aiming to assess the prevalence, clinical features, and comorbidities of the disease. Methods: We included all LPAC cases diagnosed between 2001 and 2016 in 11 French centres. Controls consisted of all patients who underwent a cholecystectomy for common gallstone disease in a single non-academic centre over 1 year. A logistic regression analysis was used to identify the clinical features associated with LPAC syndrome across several patient strata with increasing levels of diagnostic confidence. The ratio between the incident cases of LPAC syndrome and the total number of cholecystectomies for gallstones was used to assess the relative prevalence of the disease. Results: In this study, 308 cases and 206 controls were included. LPAC syndrome accounted for 0.5–1.9% of all patients admitted with symptomatic gallstone disease. Age at first symptoms

Subjects: Hepatology
Abstract: This study aimed to evaluate the ability of single nucleotide polymorphisms (SNPs) to refine hepatocellular carcinoma (HCC) risk stratification.Six SNPs in PNPLA3, TM6SF2, HSD17B13, APOE, and MBOAT7 affecting lipid turnover and one variant involved in the Wnt-β-catenin pathway (WNT3A-WNT9A rs708113) were assessed in patients with alcohol-related and/or HCV-cured cirrhosis included in HCC surveillance programs (prospective CirVir and CIRRAL cohorts). Their prognostic value for HCC occurrence was assessed using Fine-Gray models combined into a 7-SNP genetic risk score (GRS). Prediction ability of two clinical scores (a routine nongenetic model determined by multivariate analysis and the external aMAP score) without then with the addition of the GRS was evaluated by C-indices. The standardized net benefit was derived from decision curves.Among 1145 patients, 86 (7.5%) developed HCC after 43.7 months. PNPLA3 and WNT3A-WNT9A variants were independently associated with HCC occurrence. The GRS stratified the population into 3 groups with progressively increased 5-yr HCC incidence [Group 1 (n=627, 5.4%), Group 2 (n=276, 10.7%), and Group 3 (n=242, 15.3%); P0.001]. The multivariate model identified age, male sex, diabetes, platelet count, GGT levels, albuminemia and the GRS as independent risk factors. The clinical model performance for 5-yr HCC prediction was similar to that of the aMAP score (C-Index 0.769). The addition of the GRS to both scores modestly improved their performance (C-Index 0.786 and 0.783, respectively). This finding was confirmed by decision curve analyses showing only fair clinical net benefit.Patients with cirrhosis can be stratified into HCC risk classes by variants affecting lipid turnover and Wnt-β-catenin pathway. The incorporation of this genetic information modestly improves the performance of clinical scores.The identification of patients at higher probability of developing liver cancer is pivotal to improve the performance of surveillance. Risk assessment can be achieved by combining several clinical and biological parameters used in routine practice. The addition of patients' genetic characteristics can modestly improve this prediction and will ultimately pave the way for precision medicine in patients eligible for HCC surveillance, allowing physicians to trigger personalized screening strategies.

Abstract: BACKGROUND: Opportunity to redefine the care journeys for those living with primary biliary cholangitis (PBC) includes facilitating access to enhanced (PBC-dedicated) programmes by nonspecialist risk 'flagging' of patients. OBJECTIVE: To develop a nonexpert PBC stratification tool to help care pathway choices (standard vs. enhanced) choices in PBC. METHODS: We included ursodeoxycholic acid-treated patients with PBC from the Global PBC Study Group. The performance of baseline and 1-year clinical markers with transplant-free survival was assessed to develop the 'ABA' tool using Age (A), Bilirubin (B), and Alkaline phosphatase (A). Added value of fibrosis estimation was assessed. RESULTS: 'ABA' classification mapped three risk groups (n = 2226): low [Age > 50 years, bilirubin ≤ 1 × ULN, alkaline phosphatase (ALP) ≤ 3 × ULN], high (Age ≤ 50 years, bilirubin > 1 × ULN, ALP > 3 × ULN), and intermediate (other). Transplant-free survival at 10 years in the low-, intermediate-, and high-risk groups were 89, 77, and 59% at baseline and 86, 76, and 40% at 1 year, respectively. We propose that high-risk patients at baseline be directly triaged to enhanced (PBC-dedicated) care and the remaining be reassessed at 1 year. Modelling showed after 1 year 46% patients were proposed to enhanced care and 54% to standard care. The 'ABA' mapped pathways facilitated identification of patients at risk based on a young age, as compared to traditional liver biochemical stratification. In patients proposed to standard care, estimated fibrosis stage had ongoing prognostic value. CONCLUSION: Nonspecialist use of the 'ABA' risk tool could prioritize care journey choices for patients with PBC.

Abstract: BACKGROUND & AIMS: Liver stiffness measurement (LSM) by vibration-controlled transient elastography (VCTE) has been shown to predict outcomes of patients with primary biliary cholangitis (PBC) in small-size studies. We aimed to validate the prognostic value of LSM in a large cohort study. METHODS: We performed an international, multicentre, retrospective follow-up study of 3,985 patients with PBC seen at 23 centres in 12 countries. Eligibility criteria included at least 1 reliable LSM by VCTE and a follow-up ≥ 1 year. Independent derivation (n = 2,740) and validation (n = 568) cohorts were built. The primary endpoint was time to poor clinical outcomes defined as liver-related complications, liver transplantation, or death. Hazard ratios (HRs) with CIs were determined using a time-dependent multivariable Cox regression analysis. RESULTS: LSM was independently associated with poor clinical outcomes in the derivation (5,324 LSMs, mean follow-up 5.0 ± 3.1 years) and validation (1,470 LSMs, mean follow-up 5.0 ± 2.8 years) cohorts: adjusted HRs (95% CI) per additional kPa were 1.040 (1.026-1.054) and 1.042 (1.029-1.056), respectively (p

Abstract: A beneficial effect of bezafibrate (BZF) on symptoms and biochemical features of primary biliary cholangitis (PBC) has been reported in patients with an incomplete response to ursodeoxycholic acid (UDCA), but long-term effects on survival remain unknown. In Japan, BZF has been used as a de facto second-line therapy for PBC since 2000. Herein, we compared the survival rates between patients treated with and those without BZF in a large nationwide Japanese PBC cohort.All consecutively registered patients of this cohort who started UDCA therapy from 2000 onwards and had a follow-up ≥1 year were included. Association between BZF exposure and mortality or need for liver transplantation (LT) was assessed using time-dependent, multivariable-and propensity score-adjusted Cox proportional hazards models. Clinical benefit was quantified using the number needed to treat (NNT).Of 3,908 eligible patients, 3,162 (81%) received UDCA only and 746 (19%) UDCA and BZF over 17,360 and 3,932 patient-years, respectively. During follow-up, 183 deaths (89 liver-related) and 21 LT were registered. Exposure to combination therapy was associated with a significant decrease in all-cause and liver-related mortality or need for LT (adjusted hazard ratios: 0.3253, 95% CI 0.1936-0.5466 and 0.2748, 95% CI 0.1336-0.5655, respectively; p0.001 for both). This association was consistent across various risk groups at baseline. The NNTs with combination therapy to prevent 1 additional death or LT over 5, 10, and 15 years were 29 (95% CI 22-46), 14 (10-22), and 8 (6-15), respectively.In a large retrospective cohort study of treatment effects in patients with PBC, the addition of BZF to UDCA was associated with improved prognosis.The long-term efficacy of bezafibrate (BZF) on liver transplantation (LT) - free survival in patients with PBC and an incomplete response to ursodeoxycholic acid (UDCA) remains to be determined. In this Japanese nationwide retrospective cohort study, the use of UDCA-BZF combination therapy, compared to UDCA alone, was associated with a lower risk of all-cause and liver-related mortality or need for LT. These results indicate that BZF is so far the only drug in PBC to have demonstrated efficacy in improving symptoms, biochemical markers, and long-term outcomes.

The established goals of treatment of PBC are prevention of end-stage liver disease and amelioration of associated symptoms. The European Association for the Study of the Liver (EASL) management guidelines provide extensive recommendations on the diagnosis and management of PBC. Areas covered: This article describes the development by expert consensus of a 'PBC Integrated Patient Care Pathway' to simplify and standardize the management of PBC for clinicians based on current practice. Expert opinion: Guideline adoption is potentially poor in practice since most patients with PBC in the community are seen by general gastroenterologists or hepatologists without a special interest in autoimmune liver disease. The PBC Integrated Patient Care Pathway is a best practice tool for clinicians designed to complement the EASL Clinical Practice Guidelines for the diagnosis and management of PBC patients. It gives clinicians a practical decision tree of the key steps in PBC management, thereby providing a simplified framework and an opportunity for more uniform practice that supports the safe and timely adoption of varied models of care provision to patients with PBC.

Abstract: Background & aims Porto-sinusoidal vascular liver disease (PSVD) is a rare cause of portal hypertension. PSVD is still often misdiagnosed as cirrhosis, emphasizing the need to improve PSVD diagnosis strategies. Data on liver stiffness measurement (TE-LSM) using transient elastography, in PSVD are limited. The aim of this study was to evaluate the accuracy of TE-LSM to discriminate PSVD from cirrhosis in patients with signs of portal hypertension. Approach & results Retrospective multicenter study comparing TE-LSM in patients with PSVD, according to VALDIG criteria, to patients with compensated biopsy-proven cirrhosis related to alcohol (n=117), hepatitis C virus (HCV) infection (n=110) or non-alcoholic fatty liver disease (NAFLD) (n=46). All patients had at least one sign of portal hypertension among gastroesophageal varices, splenomegaly, porto-systemic collaterals, history of ascites or platelet count Conclusions This study including a total of 155 patients with PSVD and 273 patients with cirrhosis demonstrates that TE-LSM 20 kPa, PSVD is highly unlikely.

Abstract: Background & Aims In acute severe autoimmune hepatitis (AS-AIH), the optimal timing for liver transplantation (LT) remains controversial. The objectives of this study were to determine early predictive factors for a non-response to corticosteroids and to propose a score to identify patients in whom LT is urgently indicated. Methods This was a retrospective, multicenter study (2009-2016). A diagnosis of AS-AIH was based on: i) Definite or probable AIH based on the simplified IAIHG score; ii) international normalized ratio (INR) ≥1.5 and/or bilirubin >200 μmol/L; iii) No previous history of AIH; iv) Histologically proven AIH. A treatment response was defined as LT-free survival at 90 days. The evolution of variables from corticosteroid initiation (day-D0) to D3 was estimated from: Δ%3 = (D3–D0)/D0. Results A total of 128 patients were included, with a median age of 52 (39–62) years; 72% were female. Overall survival reached 88%. One hundred and fifteen (90%) patients received corticosteroids, with a LT-free survival rate of 66% at 90 days. Under multivariate analysis, D0-INR (odds ratio [OR] 6.85; 95% CI 2.23–21.06; p Conclusion In patients with AS-AIH, INR at the introduction of corticosteroids and the evolution of INR and bilirubin are predictive of LT or death. Within 3 days of initiating corticosteroids, the SURFASA score can identify non-responders who require a referral for LT. This score needs to be validated in a prospective cohort. Lay summary The management of patients with acute severe autoimmune hepatitis is highly challenging, particularly regarding their early referral for liver transplantation. We found that international normalized ratio at the initiation of corticosteroid therapy and the evolution of international normalized ratio and bilirubin values after 3 days of therapy were highly predictive of liver transplantation or death. We are thus proposing a score that combines these variables and identifies patients in whom liver transplantation is urgently required.

Abstract: Background & Aims: Recurrence of primary biliary cholangitis (PBC) after liver transplantation (LT) is frequent and can impair graft and patient survival. Ursodeoxycholic acid (UDCA) is the current standard therapy for PBC. We investigated the effect of preventive exposure to UDCA on the incidence and long-term consequences of PBC recurrence after LT. Methods: We performed a retrospective cohort study in 780 patients transplanted for PBC, between 1983–2017 in 16 centers (9 countries), and followed-up for a median of 11 years. Among them, 190 received preventive UDCA (10–15 mg/kg/day). The primary outcome was histological evidence of PBC recurrence. The secondary outcomes were graft loss, liver-related death, and all-cause death. The association between preventive UDCA and outcomes was quantified using multivariable-adjusted Cox and restricted mean survival time (RMST) models. Results: While recurrence of PBC significantly shortened graft and patient survival, preventive exposure to UDCA was associated with reduced risk of PBC recurrence (adjusted hazard ratio [aHR] 0.41; 95% CI 0.28–0.61; p

Abstract: PRIMARY BILIARY CHOLANGITIS Primary biliary cholangitis (formally primary biliary cirrhosis, PBC) is the most common chronic cholestatic liver disease in humans. It is a presumed autoimmune liver disease, characterized by inflammation and progressive destruction of small bile ducts. Without treatment, PBC progresses towards liver fibrosis and, ultimately, cirrhosis. Women older than 40 are more likely affected. Pruritus and tiredness are the most common symptoms but they are frequently lacking. Diagnosis is made by the association of chronic biochemical features of cholestasis (parallel increase in ALP and GGT) and presence of specific auto-antibodies (particularly M2 anti-mitochondrial antibodies). Ursodeoxycholic acid (UDCA), which is the standard of care treatment for PBC, has dramatically improved the prognosis of the disease. However, 30 % to 40 % of patients have an inadequate biochemical response to UDCA and continue to be at high-risk of complications. In this situation, second-line treatments, including obeticholic acid or fibrates, should be considered in association with UDCA.CHOLANGITE BILIAIRE PRIMITIVE La cholangite biliaire primitive (ou anciennement cirrhose biliaire primitive, CBP) est la maladie cholestatique chronique la plus fréquente. Il s’agit d’une affection présumée auto-immune caractérisée par une inflammation et une destruction progressive des petits canaux biliaires, aboutissant, en l’absence de traitement, à une fibrose hépatique puis à une cirrhose. Elle atteint majoritairement les femmes (90 % des cas) de plus de 40 ans. Les signes cliniques révélateurs (prurit et asthénie) sont inconstants et peu spécifiques. Le diagnostic repose sur l’association d’une cholestase biologique (élévation concomitante des PAL et de la GGT) chronique et la présence d’auto-anticorps spécifiques (en particulier anti-mitochondrie de type 2). Le traitement de référence est l’acide ursodésoxycholique (AUDC) qui a fortement amélioré le pronostic de la CBP. Dans 30 à 40 % des cas, la réponse biologique à l’AUDC est insuffisante et des traitements complémentaires sont nécessaires, parmi lesquels figurent actuellement l’acide obéticholique et les fibrates.

Abstract: International audience; Background: Patients with primary sclerosing cholangitis (PSC) and inflammatory bowel disease (IBD) are at risk of biliary tract cancer and liver damage (possibly leading to liver transplantation), and are often treated for IBD with thiopurines and/or tumour necrosis factor antagonists (anti-TNF) on a long-term basis.Aims: To assess the risk of biliary tract cancer and liver transplantation in patients exposed to thiopurines and/or anti-TNF in a French nationwide cohort.Methods: We performed a population-based study of patients aged 18 years or older with PSC and IBD in the French national health insurance database. Patients were followed from 1 January 2009 to 31 December 2018. The risks of biliary tract cancer and liver transplantation associated with thiopurines and anti-TNF exposure were assessed with marginal structural Cox proportional hazard models, adjusting for baseline demographics and comorbidities, and time-varying medications and PSC activity.Results: Among the 1929 patients with PSC and IBD included, 37 biliary tract cancers and 83 liver transplantations occurred. Compared with patients not exposed to thiopurines or anti-TNF agents, patients exposed to thiopurines (hazard ratio [HR], 1.05; 95% confidence interval [CI], 0.39–2.82) or anti-TNF agents (HR, 0.59; 95% CI, 0.13–2.80) had no excess risk of biliary tract cancer. Similarly, patients exposed to thiopurines (HR, 0.67; 95% CI, 0.30–1.48) or anti-TNF agents (HR, 0.68; CI, 0.22–2.09) had no excess risk of liver transplantation.ConclusionsPatients with PSC and IBD who are exposed to thiopurines or anti-TNF agents are not at excess risk of biliary tract cancer or liver transplantation.

Abstract: Primary sclerosing cholangitis (PSC) is a rare and chronic cholestatic liver disease of unknown cause commonly associated with inflammatory bowel disease (IBD) and characterized by progressive obliterative fibro-inflammation of the biliary tree. Although the natural course is highly variable, PSC is often progressive, leading to biliary cirrhosis and its complications. In addition, PSC is a condition harbouring broad neoplastic potential with increased susceptibility for the development of both biliary and colon cancer. As in other chronic liver diseases, non-invasive methods play a major role in the diagnosis and monitoring of PSC. MR cholangiography is the key exam for the diagnosis and has replaced diagnostic endoscopic retrograde cholangiopancreatography (ERCP). A strict and standardised protocol for carrying out MR cholangiography is recommended. Liver stiffness measured by FibroScan® correlates with the degree of liver fibrosis, has a prognostic value and should be repeated during follow-up. Invasive methods still play an important role, especially ERCP which is indicated for therapeutic purposes or for endo-biliary sample collection in suspected cholangiocarcinoma (following discussion in a multidisciplinary team meeting) and total colonoscopy which is recommended at the initial diagnosis of any PSC and annually in patients with IBD.

Abstract: Background and aims The ABCC2 gene is implicated in Dubin-Johnson syndrome (DJS), a rare autosomal recessive liver disorder. The primary aim of this study was to determine the diagnostic value of ABCC2 genetic testing in the largest cohort of DJS reported to date. The high number of patients with cholestatic manifestations in this series prompted us to evaluate the genetic contribution of rare, potentially pathogenic ABCC2 variants to other inherited cholestatic disorders. Methods The cohort study included 32 patients with clinical DJS diagnosis, and 372 patients referred for the following disorders: low phospholipid-associated cholelithiasis (LPAC) syndrome, intrahepatic cholestasis of pregnancy (ICP) and benign recurrent intrahepatic cholestasis (BRIC). ABCC2 was screened by next-generation sequencing. Results Most patients with clinical DJS had positive genetic diagnosis (n = 30; 94%), with a great diversity of point mutations and copy number variations in ABCC2. Strikingly, eight (27%) of these patients showed transient cholestatic features at presentation: four neonatal cholestasis, two ICP, one contraceptive-induced cholestasis and one sporadic cholestasis. Conversely, the frequency of rare, heterozygous, potentially pathogenic ABCC2 variants in patients with LPAC, ICP or BRIC did not differ significantly from that of the general population. Conclusions This large series reveals that DJS is a highly homogeneous Mendelian disorder involving a large spectrum of ABCC2 variants. Genetic testing is crucial to establish early DJS diagnosis in patients with atypical presentations, such as neonatal cholestasis. This study also provides no evidence for the contribution of rare, potentially pathogenic ABCC2 variants to other inherited cholestatic disorders.

Abstract: International audience; BACKGROUND and AIMS: The factors predicting hepatocellular carcinoma (HCC) occurrence in chronic hepatitis B need to be precisely known to improve its detection. We identified pathways and individual predictive factors associated with HCC in the ANRS CO22 HEPATHER cohort. METHODS: The study analyzed HBV-infected patients recruited at 32 French expert hepatology centers from August 6, 2012, to December 31, 2015. We excluded patients with chronic HCV, HDV and a history of HCC, decompensated cirrhosis or liver transplantation. Structural equation models were developed to characterize the causal pathways leading to HCC occurrence. The association between clinical characteristics (age, gender, body-mass index, liver fibrosis, alcohol consumption, smoking status, diabetes, hypertension, dyslipidemia, alpha-fetoprotein, HBV DNA levels, antiviral therapy) and incident HCC was quantified. RESULTS: Among the 4,489 patients included, 33 patients reported incident HCC. The median follow-up was 45.2 months. Age (β = 0.18 by decade, 95% CI 0.14-0.23), male gender (β = 0.23, 95% CI 0.18-0.29), metabolic syndrome (β = 0.28, 95% CI 0.22-0.33), alcohol consumption (β = 0.09, 95% CI 0.05-0.14) and HBV DNA (β = 0.25, 95% CI 0.17-0.34) had a significant and direct effect on the occurrence of advanced liver fibrosis. Liver fibrosis (β = 0.71, 95% CI 0.55-0.87) predicted, in turn, the occurrence of HCC. CONCLUSIONS: Liver fibrosis mediates the effects of age, gender, alcohol, metabolic syndrome and HBV DNA on the occurrence of HCC. Elderly men with chronic hepatitis B, risky alcohol use, advanced liver fibrosis, metabolic syndrome and high HBV DNA levels should be monitored closely to detect the development of HCC.

Abstract: BACKGROUND: Diagnostic tools for liver disease can now include estimation of the grade of hepatic steatosis (S0 to S3). Controlled attenuation parameter (CAP) is a non-invasive method for assessing hepatic steatosis that has become available for patients who are obese (FibroScan XL probe), but a consensus has not yet been reached regarding cutoffs and its diagnostic performance. We aimed to assess diagnostic properties and identify relevant covariates with use of an individual patient data meta-analysis.METHODS: We did an individual patient data meta-analysis, in which we searched PubMed and Web of Science for studies published from database inception until April 30, 2019. Studies reporting original biopsy-controlled data of CAP for non-invasive grading of steatosis were eligible. Probe recommendation was based on automated selection, manual assessment of skin-to-liver-capsule distance, and a body-mass index (BMI) criterion. Receiver operating characteristic methods and mixed models were used to assess diagnostic properties and covariates. Patients with non-alcoholic fatty liver disease (NAFLD) were analysed separately because they are the predominant patient group when using the XL probe. This study is registered with PROSPERO, CRD42018099284.FINDINGS: 16 studies reported histology-controlled CAP including the XL probe, and individual data from 13 papers and 2346 patients were included. Patients with a mean age of 46·5 years (SD 14·5) were recruited from 20 centres in nine countries. 2283 patients had data for BMI; 673 (29%) were normal weight (BMI INTERPRETATION: CAP cutoffs varied according to cause, and can effectively recognise significant steatosis in patients with viral hepatitis. CAP cannot grade steatosis in patients with NAFLD adequately, but its value in a NAFLD screening setting needs to be studied, ideally with methods beyond the traditional histological reference standard.FUNDING: The German Federal Ministry of Education and Research and Echosens.

Abstract: Background & Aims Low-phospholipid-associated cholelithiasis (LPAC) syndrome, a rare genetic form of intrahepatic cholelithiasis in adults, is still poorly understood. We report the results of the largest-ever case-control study of patients with LPAC syndrome aiming to assess the prevalence, clinical features, and comorbidities of the disease. Methods We included all LPAC cases diagnosed between 2001 and 2016 in 11 French centres. Controls consisted of all patients who underwent a cholecystectomy for common gallstone disease in a single non-academic centre over 1 year. A logistic regression analysis was used to identify the clinical features associated with LPAC syndrome across several patient strata with increasing levels of diagnostic confidence. The ratio between the incident cases of LPAC syndrome and the total number of cholecystectomies for gallstones was used to assess the relative prevalence of the disease. Results In this study, 308 cases and 206 controls were included. LPAC syndrome accounted for 0.5–1.9% of all patients admitted with symptomatic gallstone disease. Age at first symptoms, Graphical abstract, Highlights • Low-phospholipid-associated cholelithiasis (LPAC) syndrome affects approximately 1% of adults with symptomatic cholelithiasis. • Normal weight, common bile duct stones, and lack of cholecystitis are clinical features significantly associated with this syndrome. • ABCB4 variants in patients with LPAC may be associated with an increased personal or family risk of hepato-biliary cancer.

Abstract: Background: Obeticholic acid (OCA) and fibrates are second-line therapies for patients with primary biliary cholangitis (PBC) with an inadequate response to ursodeoxycholic acid (UDCA). Aim: To know whether OCA and fibrates, administered together in combination with UDCA, have additive beneficial effects in patients with difficult-to-treat PBC. Methods: PBC patients treated for ≥3months with UDCA, OCA and fibrates (bezafibrate or fenofibrate) due to failure of either second-line therapy were included in a multicentre, uncontrolled retrospective cohort study. Changes in biochemical liver tests and pruritus were analysed using a generalised linear mixed-effect model. Results: Among 58 patients included, half received OCA as second-line and fibrates as third-line therapy (Group OCA-Fibrate), while the other half had the inverse therapeutic sequence (Group Fibrate-OCA). The mean duration of triple therapy was 11months (range 3-26). Compared to dual therapy, triple therapy was associated with a significant gain in alkaline phosphatase (ALP) reduction: 22% per first year (95% CI 12%-31%), an effect that was stronger in OCA-Fibrate than in Fibrate-OCA group. Triple therapy was associated with a 3.4 (95% CI 1.4-8.2) odds ratio (OR) of reaching normal ALP and with a significant decrease in gamma-glutamyl transpeptidase (GGT), alanine aminotransferase (ALT), aspartate aminotransferase (AST) and total bilirubin. The ORs of achieving the Paris-2 and Toronto criteria of adequate biochemical response were 6.8 (95% CI 2.8-16.7) and 9.2 (95% CI 3.4-25.1) respectively. Finally, triple therapy significantly improved pruritus in OCA-Fibrate but not in Fibrate-OCA group. Conclusions: Triple therapy with UDCA, OCA and fibrates is able to normalise biochemical liver tests and improve pruritus in patients with difficult-to-treat PBC.

Abstract: International audience; GBCA gadolinium-based contrast agent MR magnetic resonance MRC magnetic resonance cholangiography PSC primary sclerosing cholangitis VCTE vibration controlled transient elastography Dear editor, We read with interest the review written by Mahzar and Russo about non-invasive prognostic tests for primary sclerosing cholangitis (PSC) 1. Although rare, PSC is a serious disease, associated with potentially lethal complications, notably cirrhosis and cholangiocarcinoma 2. Liver transplantation is the only curative treatment for PSC and median transplant-free survival is approximately 12-21 years after diagnosis 3. Identification of prognostic factors is essential for tailoring the follow-up strategies and testing new therapeutic modalities in homogeneous groups of PSC patients. As detailed in this review, over the last twenty years, different teams across the world, including ours, have identified several noninvasive prognostic tests for PSC patients 1. First, our team demonstrated in a large retrospective study that liver stiffness measured by vibration-controlled transient elastography (VCTE) was an independent predictive marker of survival in PSC patients 4. Next, we built 2 magnetic resonance (MR) risk scores (with and without gadolinium-based contrast agent (GBCA) administration) 5 , called Anali scores, and showed that they were able to predict adverse outcome-free survival (defined by survival without liver transplantation or cirrhosis

Abstract: Background & Aims Refining hepatocellular carcinoma (HCC) surveillance programs requires improved individual risk prediction. Thus, we aimed to develop algorithms based on machine learning approaches to predict the risk of HCC more accurately in patients with HCV-related cirrhosis, according to their virological status. Methods Patients with compensated biopsy-proven HCV-related cirrhosis from the French ANRS CO12 CirVir cohort were included in a semi-annual HCC surveillance program. Three prognostic models for HCC occurrence were built, using (i) Fine-Gray regression as a benchmark, (ii) single decision tree (DT), and (iii) random survival forest for competing risks survival (RSF). Model performance was evaluated from C-indexes validated externally in the ANRS CO22 Hepather cohort (n = 668 enrolled between 08/2012–01/2014). Results Out of 836 patients analyzed, 156 (19%) developed HCC and 434 (52%) achieved sustained virological response (SVR) (median follow-up 63 months). Fine-Gray regression models identified 6 independent predictors of HCC occurrence in patients before SVR (past excessive alcohol intake, genotype 1, elevated AFP and GGT, low platelet count and albuminemia) and 3 in patients after SVR (elevated AST, low platelet count and shorter prothrombin time). DT analysis confirmed these associations but revealed more complex interactions, yielding 8 patient groups with varying cancer risks and predictors depending on SVR achievement. On RSF analysis, the most important predictors of HCC varied by SVR status (non-SVR: platelet count, GGT, AFP and albuminemia; SVR: prothrombin time, ALT, age and platelet count). Externally validated C-indexes before/after SVR were 0.64/0.64 [Fine-Gray], 0.60/62 [DT] and 0.71/0.70 [RSF]. Conclusions Risk factors for hepatocarcinogenesis differ according to SVR status. Machine learning algorithms can refine HCC risk assessment by revealing complex interactions between cancer predictors. Such approaches could be used to develop more cost-effective tailored surveillance programs. Lay summary Patients with HCV-related cirrhosis must be included in liver cancer surveillance programs, which rely on ultrasound examination every 6 months. Hepatocellular carcinoma (HCC) screening is hampered by sensitivity issues, leading to late cancer diagnoses in a substantial number of patients. Refining surveillance periodicity and modality using more sophisticated imaging techniques such as MRI may only be cost-effective in patients with the highest HCC incidence. Herein, we demonstrate how machine learning algorithms (i.e. data-driven mathematical models to make predictions or decisions), can refine individualized risk prediction.

Abstract: International audience; 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. A Cox model adapted to the identification of prognostic factors (competitive risks) was used.Results: From the entire cohort, one (or more)de novo malignancy was reported in 1480 L T recipients (13.45%). The probability to develop a de novo malignancy after LT was 2.07% at 1 year, 13.30% at 5 years, and 28.01% at 10 years. Of the known reported malignancies, the most common malignancies were hematological malignancy (22.36%), non-melanoma skin cancer (19.53%) and lung cancer (12.36%). According to Fine and Gray competing risks regression multivariate analysis, were significant risk factors for post-LT de novo malignancy: recipient age (Subdistribution Hazard Ratio (SHR) = 1.03 95%CI 1.03-1.04), male gender (SHR = 1.45 95%CI 1.27-1.67), non-living donor (SHR = 1.67 95%CI 1.14-2.38), a first LT (SHR = 1.35 95%CI 1.09-1.69) and the type of initial liver disease (alcohol-related liver disease (SHR = 1.63 95%CI 1.22-2.17), primary sclerosing cholangitis (SHR = 1.98 95%CI 1.34-2.91), and primary liver tumor (SHR = 1.88 95%CI 1.41-2.54)). Initial immunosuppressive regimen had no significant impact.Conclusion: The present study confirms that LT recipient characteristics are associated with the risk ofde novo malignancy and this underlines the need for personalized screening in order to improve survival.

Abstract: International audience; Background & aims: HDV infection causes severe chronic liver disease in individuals infected with HBV. However, the factors associated with poor prognosis are largely unknown. Thus, we aimed to identify prognostic factors in patients with HDV infection.Methods: The French National Reference Centre for HDV performed a nationwide retrospective study on 1,112 HDV-infected patients, collecting epidemiological, clinical, virological and histological data from the initial referral to the last recorded follow-up.Results: The median age of our cohort was 36.5 (29.9-43.2) years and 68.6% of our cohort were male. Most patients whose birthplace was known were immigrants from sub-Saharan Africa (52.5%), southern and eastern Europe (21.3%), northern Africa and the Middle East (6.2%), Asia (5.9%) and South America (0.3%). Only 150 patients (13.8%) were French native. HDV load was positive in 659 of 748 tested patients (88.1%). HDV-1 was predominant (75.9%), followed by sub-Saharan genotypes: HDV-5 (17.6%), HDV-7 (2.9%), HDV-6 (1.8%) and HDV-8 (1.6%). At referral, 312 patients (28.2%) had cirrhosis, half having experienced at least 1 episode of hepatic decompensation. Cirrhosis was significantly less frequent in African than in European patients regardless of HDV genotype. At the end of follow-up (median 3.0 [0.8-7.2] years), 48.8% of the patients had developed cirrhosis, 24.2% had ≥1 episode(s) of decompensation and 9.2% had hepatocellular carcinoma. European HDV-1 and African HDV-5 patients were more at risk of developing cirrhosis. Persistent replicative HDV infection was associated with decompensation, hepatocellular carcinoma and death. African patients displayed better response to interferon therapy than non-African patients (46.4% vs. 29.1%, p

Abstract: Overlap syndromes (OSs) between primary biliary cholangitis (PBC) and autoimmune hepatitis (AIH) represent rare forms of PBC and AIH. The diagnosis of OS is based on the presence or sequential development of biochemical, serological, and histologic features of the two diseases. Liver biopsy is mandatory when PBC-AIH OS is suspected and moderate or interface hepatitis is a fundamental component for the diagnosis of OS. OS should not be over-diagnosed, and it is generally recommended to use the Paris diagnostic criteria. Patients may present with one or more associated extra-hepatic autoimmune disease. PBC-AIH OS seems to have a more severe presentation and course compared to conventional PBC. Treatment of OS is empiric and includes ursodeoxycholic acid (UDCA) for the cholestatic component and immunosuppressive agents for the hepatitic component. Immunosuppressive treatment in addition to UDCA is recommended in patients with severe interface hepatitis. In those with moderate interface hepatitis, the dominant clinical feature should be treated first and therapy adjusted according to the response.

Abstract: Sofosbuvir plus daclatasvir with or without ribavirin has demonstrated a high efficacy and an acceptable safety profile in clinical trials of patients infected with genotype 2 hepatitis Cvirus (HCV); however, there are currently no real-world data available for this regimen. To evaluate the real-life safety and efficacy of sofosbuvir/daclatasvir with or without ribavirin in genotype 2 HCV patients in the French cohort ANRS CO22 HEPATHER(NCT01953458). In this ongoing, national, multicentre, prospective, observational study, we observed patients with HCV genotype 2 infection who initiated treatment with sofosbuvir (400 mg/d) plus daclatasvir with or without ribavirin (1-1.2 g/d). Patients were divided into two treatment groups: sofosbuvir/daclatasvir with or without ribavirin (12 weeks/24 weeks). The primary end point was a sustained virological response at week 12 following the end of therapy. Overall, 88% and 91% of patients achieved a sustained virological response following 12 and 24 weeks of treatment with sofosbuvir/daclatasvir with or without ribavirin, respectively. The most common adverse events were asthenia (29%), headache (15%) and fatigue (20%), and ribavirin addition was associated with a higher rate of adverse events and treatment discontinuation. Sofosbuvir/daclatasvir with or without ribavirin was associated with lower rates of sustained virological response in the real-life setting compared with the clinical setting and demonstrated suboptimal efficacy for the treatment of patients with genotype 2 chronic HCV.

Abstract: Background & Aims Reinforced hepatocellular carcinoma (HCC) surveillance using magnetic resonance imaging (MRI) could increase early tumour detection but faces cost-effectiveness issues. In this study, we aimed to evaluate the cost-effectiveness of MRI for the detection of very early HCC (Barcelona Clinic Liver Cancer [BCLC] 0) in patients with an annual HCC risk >3%. Methods French patients with compensated cirrhosis included in 4 multicentre prospective cohorts were considered. A scoring system was constructed to identify patients with an annual risk >3%. Using a Markov model, the economic evaluation estimated the costs and life years (LYs) gained with MRI vs. ultrasound (US) monitoring over a 20-year period. The incremental cost-effectiveness ratio (ICER) was calculated by dividing the incremental costs by the incremental LYs. Results Among 2,513 patients with non-viral causes of cirrhosis (n = 840) and/or cured HCV (n = 1,489)/controlled HBV infection (n = 184), 206 cases of HCC were detected after a 37-month follow-up. When applied to training (n = 1,658) and validation (n = 855) sets, the construction of a scoring system identified 33.4% and 37.5% of patients with an annual HCC risk >3% (3-year C-Indexes 75 and 76, respectively). In patients with a 3% annual risk, the incremental LY gained with MRI was 0.4 for an additional cost of €6,134, resulting in an ICER of €15,447 per LY. Compared to US monitoring, MRI detected 5x more BCLC 0 HCC. The deterministic sensitivity analysis confirmed the impact of HCC incidence. At a willingness to pay of €50,000/LY, MRI screening had a 100% probability of being cost-effective. Conclusions In the era of HCV eradication/HBV control, patients with annual HCC risk >3% represent one-third of French patients with cirrhosis. MRI is cost-effective in this population and could favour early HCC detection. Lay summary The early identification of hepatocellular carcinoma in patients with cirrhosis is important to improve patient outcomes. Magnetic resonance imaging could increase early tumour detection but is more expensive and less accessible than ultrasound (the standard modality for surveillance). Herein, using a simple score, we identified a subgroup of patients with cirrhosis (accounting for >one-third), who were at increased risk of hepatocellular carcinoma and for whom the increased expense of magnetic resonance imaging would be justified by the potential improvement in outcomes., Graphical abstract, Highlights • HCC risk stratification in patients with cirrhosis aims at improving performance of cancer surveillance. • Using a simple scoring system, one-third of patients with cirrhosis with an annual HCC risk >3% can be easily identified. • Semi-annual surveillance using MRI in this population could enable the cost-effective detection of 5x more BCLC 0 HCCs.

Abstract: Background & Aims Primary sclerosing cholangitis (PSC) has a variable, often progressive, course. Magnetic resonance cholangiography (MRC) is used in the diagnosis of PSC. Magnetic resonance risk scoring systems, called Anali without and with gadolinium, are used to predict disease progression, determined by radiologic factors. We aimed to assess the prognostic value of Anali scores in patients with PSC and validate our findings in a separate cohort. Methods We performed a retrospective study of patients with large-duct PSC (internal cohort, 119 patients in France; external cohort, 119 patients in Canada, Italy, and the United Kingdom). All the first-available MRC results were reviewed by 2 radiologists and the Anali scores were calculated as follows: Anali without gadolinium = (1× dilatation of intrahepatic bile ducts) + (2× dysmorphy) + (1× portal hypertension); Anali with gadolinium = (1× dysmorphy) + (1× parenchymal enhancement heterogeneity). The primary end point was survival without liver transplantation or cirrhosis decompensation. The prognostic value of Anali scores was assessed by Cox regression modeling. Results During a total of 549 patient-years for the internal cohort and 497 patient-years for the external cohort, we recorded 2 and 8 liver transplantations, 4 and 3 liver-related deaths, and 26 and 25 cirrhosis decompensations, respectively. In the univariate analysis, factors associated with survival without liver transplantation or cirrhosis decompensation in the internal cohort were as follows: serum levels of bilirubin, aspartate aminotransferase, alanine aminotransferase, γ-glutamyl transferase, alkaline phosphatase, albumin, and Anali scores. Anali scores without and with gadolinium identified patients' survival without liver transplantation or cirrhosis decompensation with a c-statistic of 0.89 (95% CI, 0.84–0.95) and 0.75 (95% CI, 0.64–0.87), respectively. Independent prognostic factors identified by multivariate analysis were Anali scores and bilirubinemia. The prognostic value of Anali scores was confirmed in the external cohort. Conclusions In internal and external cohorts, we found that Anali scores, determined from MRC, were associated with outcomes of patients with PSC. These scores might be used as prognostic factors.

Abstract: ObjectivePrimary sclerosing cholangitis (PSC) is a genetically complex, inflammatory bile duct disease of largely unknown aetiology often leading to liver transplantation or death. Little is known about the genetic contribution to the severity and progression of PSC. The aim of this study is to identify genetic variants associated with PSC disease progression and development of complications.DesignWe collected standardised PSC subphenotypes in a large cohort of 3402 patients with PSC. After quality control, we combined 130 422 single nucleotide polymorphisms of all patients—obtained using the Illumina immunochip—with their disease subphenotypes. Using logistic regression and Cox proportional hazards models, we identified genetic variants associated with binary and time-to-event PSC subphenotypes.ResultsWe identified genetic variant rs853974 to be associated with liver transplant-free survival (p=6.07×10–9). Kaplan-Meier survival analysis showed a 50.9% (95% CI 41.5% to 59.5%) transplant-free survival for homozygous AA allele carriers of rs853974 compared with 72.8% (95% CI 69.6% to 75.7%) for GG carriers at 10 years after PSC diagnosis. For the candidate gene in the region, RSPO3, we demonstrated expression in key liver-resident effector cells, such as human and murine cholangiocytes and human hepatic stellate cells.ConclusionWe present a large international PSC cohort, and report genetic loci associated with PSC disease progression. For liver transplant-free survival, we identified a genome-wide significant signal and demonstrated expression of the candidate gene RSPO3 in key liver-resident effector cells. This warrants further assessments of the role of this potential key PSC modifier gene.

Abstract: Primary sclerosing cholangitis (PSC) is strongly associated with several human leukocyte antigen (HLA) haplotypes. Due to extensive linkage disequilibrium and multiple polymorphic candidate genes in the HLA complex, identifying the alleles responsible for these associations has proven difficult. We aimed to evaluate whether studying populations of admixed or non-European descent could help in defining the causative HLA alleles. When assessing haplotypes carrying HLA-DRB1*13:01 (hypothesized to specifically increase the susceptibility to chronic cholangitis), we observed that every haplotype in the Scandinavian PSC population carried HLA-DQB1*06:03. In contrast, only 65% of HLA-DRB1*13:01 haplotypes in an admixed/non-European PSC population carried this allele, suggesting that further assessments of the PSC-associated haplotype HLA-DRB1*13:01-DQA1*01:03-DQB1*06:03 in admixed or multi-ethnic populations could aid in identifying the causative allele.

47. Biologie des maladies cholestatiques chroniques de l’adulte

Author: Sara Lemoinne and Olivier Chazouillères
Subjects: Medical Laboratory Technology, Biochemistry (medical), Analytical Chemistry
Abstract: Resume La cholestase est definie par un defaut de transport des acides biliaires du foie vers l’intestin. Les tests de cholestase refletent d’une part les lesions des hepatocytes ou des cellules epitheliales biliaires induites par l’accumulation des acides biliaires (enzymes hepatiques) et d’autre part les alterations fonctionnelles de la secretion biliaire (bilirubine, acides biliaires). La ponction biopsie hepatique garde une place dans le diagnostic etiologique d’une cholestase chronique. Les principales maladies cholestatiques chroniques de l’adulte sont la cholangite biliaire primitive (CBP) et la cholangite sclerosante primitive (CSP). Des facteurs pronostiques ont ete identifies. La mesure de la souplesse du foie par elastometrie semble un examen tres prometteur dans la prise en charge de ces maladies. Le traitement medical est base sur l’acide ursodesoxycholique. Cependant, de nouveaux agents anti-cholestatiques, en particulier les agonistes des recepteurs nucleaires, dont l’acide obeticholique et les fibrates, ont fait l’objet d’une evaluation preclinique et clinique prometteuse. Une amelioration de la prise en charge est donc hautement probable a court terme.

Abstract: Primary sclerosing cholangitis (PSC) is a rare progressive disorder leading to bile duct destruction; similar to 75% of patients have comorbid inflammatory bowel disease (IBD). We undertook the largest genome-wide association study of PSC (4,796 cases and 19,955 population controls) and identified four new genome-wide significant loci. The most associated SNP at one locus affects splicing and expression of UBASH3A, with the protective allele (C) predicted to cause nonstop-mediated mRNA decay and lower expression of UBASH3A. Further analyses based on common variants suggested that the genome-wide genetic correlation (r(G)) between PSC and ulcerative colitis (UC) (r(G) = 0.29) was significantly greater than that between PSC and Crohn's disease (CD) (r(G) = 0.04) (P = 2.55 x 10(-15)). UC and CD were genetically more similar to each other (r(G) = 0.56) than either was to PSC (P
