Liver disease in germline mutations of telomere-related genes: Prevalence, clinical, radiological, pathological features, outcome, and risk factors.

BACKGROUND AND AIM: Germline mutations of telomere-related genes (TRG) induce multiorgan dysfunction, and liver-specific manifestations have not been clearly outlined. We aimed to describe TRG mutations-associated liver diseases. APPROACH AND RESULTS: Retrospective multicenter analysis of liver disease (transaminases > 30 IU/L and/or abnormal liver imaging) in patients with TRG mutations. Main measurements were characteristics, outcomes, and risk factors of liver disease in a TRG mutations cohort. The prevalence of liver disease was compared to a community-based control group (n = 1190) stratified for age and matched 1:3 for known risk factors of liver disease. Among 132 patients with TRG mutations, 95 (72%) had liver disease, with associated lung, blood, skin, rheumatological, and ophthalmological TRG diseases in 82%, 77%, 55%, 39%, and 30% of cases, respectively. Liver biopsy was performed in 52/95 patients, identifying porto-sinusoidal vascular disease in 48% and advanced fibrosis/cirrhosis in 15%. After a follow-up of 21 months (12-54), ascites, hepato-pulmonary syndrome, variceal bleeding, and HCC occurred in 14%, 13%, 13%, and 2% of cases, respectively. Five-year liver transplantation-free survival was 69%. A FIB-4 score ≥ 3·25 and ≥1 risk factor for cirrhosis were associated with poor liver transplantation-free survival. Liver disease was more frequent in patients with TRG mutations than in the paired control group [80/396, (20%)], OR 12.9 (CI 95%: 7.8-21.3, p < 0.001). CONCLUSIONS: TRG mutations significantly increase the risk of developing liver disease. Although symptoms may be mild, they may be associated with severe disease. Porto-sinusoidal vascular disease and cirrhosis were the most frequent lesions, suggesting that the mechanism of action is multifactorial.

Impact of COVID-19 on the management of hepatocellular carcinoma in a high-prevalence area: What's new 12 months later?

INTRODUCTION AND OBJECTIVES: The lockdown policy introduced in 2020 to minimize the spread of the COVID-19 pandemic, significantly affected the management and care of patients affected by hepatocellular carcinoma (HCC). The aim of this follow-up study was to determine the 12 months impact of the COVID-19 pandemic on the cohort of patients affected by HCC during the lockdown, within six French academic referral centers in the metropolitan area of Paris. MATERIALS AND METHODS: We performed a 12 months follow-up of the cross-sectional study cohort included in 2020 on the management of patients affected by HCC during the first six weeks of the COVID-19 pandemic (exposed), compared to the same period in 2019 (unexposed). Overall survival were compared between the groups. Predictors of mortality were analysed with Cox regression. RESULTS: From the initial cohort, 575 patients were included (n = 263 Exposed_COVID, n = 312 Unexposed_COVID). Overall and disease free survival at 12 months were 59.9 ± 3.2% vs 74.3 ± 2.5% (p<0.001) and 40.2 ± 3.5% vs 63.5 ± 3.1% (p<0.001) according to the period of exposure (Exposed_COVID vs Unexposed_COVID, respectively). Adjusted Cox regression revealed that the period of exposure (Exposed_COVID HR: 1.79, 95%CI (1.36, 2.35) p<0.001) and BCLC stage B, C and D (BCLC B HR: 1.82, 95%CI (1.07, 3.08) p = 0.027 - BCLC C HR: 1.96, 95%CI (1.14, 3.38) p = 0.015 - BCLC D HR: 3.21, 95%CI (1.76, 5.85) p<0.001) were predictors of death. CONCLUSIONS: Disruption of routine healthcare services because of the pandemic translated to reduced 1 year overall and disease-free survival among patients affected by HCC, in the metropolitan area of Paris, France.

Liver resection for single large hepatocellular carcinoma: a prognostic factors study.

INTRODUCTION AND OBJECTIVES: Liver resection is the only curative therapeutic option for large hepatocellular carcinoma (> 5 cm), but survival is worse than in smaller tumours, mostly due to the high recurrence rate. There is currently no proper tool for stratifying relapse risk. Herein, we investigated prognostic factors before hepatectomy in patients with a single large hepatocellular carcinoma (HCC). MATERIAL AND METHODS: We retrospectively identified 119 patients who underwent liver resection for a single large HCC in 2 tertiary academic French centres and collected pre- and post-operative clinical, biological and radiological features. The primary outcome was overall survival at five years. Secondary outcomes were recurrence-free survival at five years and prognostic factors for recurrence. RESULTS: A total of 84% of the patients were male, and the median age was 66 years old (IQR 58-74). Thirty-nine (33%) had Child-Pugh A cirrhosis, and the mean Model for End-Stage Liver Disease (MELD) score was 6 (6-6). The aetiology of liver disease was predominantly alcohol-related (48%), followed by nonalcoholic steatohepatitis (22%), hepatitis B (18%) and hepatitis C (10%). The mean tumour size was 70 mm (55-110). The median overall survival was 72.5 months (IC 95%: 56.2-88.7), and the five-year overall survival was 55.1 ± 5.5%. The median recurrence-free survival was 26.6 months (95% CI: 16.0-37.1), and the five-year recurrence-free survival rate was 37.8 ± 5%. In multivariate analysis, preoperative prognostic factors for recurrence were baseline alpha-fetoprotein (AFP) > 7 ng/mL (p<0.001), portal veinous invasion (p=0.003) and cirrhosis (p=0.020). Using these factors, we created a simple recurrence-risk scoring system that classified three groups with distinct disease-free survival medians (p<0.001): no risk factors (65 months), 1 risk factor (36 months), and ≥2 risk factors (8.9 months). CONCLUSION: Liver resection is the only curative option for large HCC, and we confirmed that survival could be acceptable in experienced centres. Recurrence is the primary issue of surgery, and we proposed a simple preoperative score to help identify patients with the most worrisome prognosis and possible candidates for combined therapy.

Origin, HDV genotype and persistent viremia determine outcome and treatment response in patients with chronic hepatitis delta.

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 <0.001). HDV viral load at baseline was significantly lower in responders than in non-responders. CONCLUSION: Place of birth, HDV genotype and persistent viremia constitute the main determinants of liver involvement and response to treatment in chronic HDV-infected patients. LAY SUMMARY: Chronic liver infection by hepatitis delta virus (HDV) is the most severe form of chronic viral hepatitis. Despite the fact that at least 15-20 million people are chronically infected by HDV worldwide, factors determining the severity of liver involvement are largely unknown. By investigating a large cohort of 1,112 HDV-infected patients followed-up in France, but coming from different areas of the world, we were able to determine that HDV genotype, place of birth (reflecting both viral and host-related factors) and persistent viremia constitute the main determinants of liver involvement and response to treatment.

Validation of Baveno VI Criteria for Screening and Surveillance of Esophageal Varices in Patients With Compensated Cirrhosis and a Sustained Response to Antiviral Therapy.

BACKGROUND & AIMS: Management of patients with cirrhosis includes endoscopic screening and surveillance to detect esophageal varices (EV) and prevent bleeding. However, the Baveno VI guidelines recommend avoiding endoscopies for patients with liver stiffness measurements below 20 kPa and platelet counts above 150,000 (favorable Baveno VI status) and endoscopic assessment of patients with higher levels of liver stiffness and platelet counts (unfavorable Baveno VI status). We aimed to validate the Baveno VI guidelines, evaluating outcomes of patients in the ANRS-CO12 CirVir cohort with compensated cirrhosis associated with hepatitis B virus (HBV) or hepatitis C virus (HCV) infection, with or without a sustained response to antiviral therapy. METHODS: We performed an ancillary study using data from 891 patients in the ANRS CO12 CirVir cohort, treated at 35 centers in France, with HCV or HBV infection and biopsy-proven cirrhosis, Child-Pugh A scores, no previous complications, and no hepatocellular carcinoma who underwent an endoscopic procedure and had interpretable liver stiffness measurements and platelet counts. Progression of portal hypertension (PHT) was defined as the onset of varices needing treatment (VNT) or PHT-related bleeding. An sustained response to antiviral therapy was defined as undetectable level of HCV RNA by polymerase chain reaction assay (<50 IU/mL) 12 weeks after the end of treatment (SVR) or an undetectable level of HBV DNA. The primary aims were to validate the Baveno VI guidelines for screening and surveillance of EV in patients with compensated cirrhosis and to study the effects of an SVR on the progression of PHT. RESULTS: A total of 200 patients achieved an SVR (22.4%) (94 patients with HCV infection, 98 patients with HBV infection, and 8 patients with both); 80 of these patients had favorable Baveno VI status and none had VNT. Progression of PHT was studied in 548 patients; during a follow-up period of 61.2 months (interquartile range, 39.5-80.6 months), 105 of these patients (19.1%) had progression of PHT. Lack of an SVR and grade 1 EV were independently associated with progression of PHT. At the time of PHT progression, all patients had unfavorable Baveno VI status. Achieving favorable Baveno VI status after an SVR was associated with the absence of PHT progression. Favorable Baveno VI status and SVR were independently associated with survival. CONCLUSIONS: In an analysis of data from a large cohort of patients with HBV- or HCV-associated cirrhosis in France, we validated the Baveno VI guidelines on screening and surveillance of PHT, even for patients who achieved a sustained response to antiviral therapy.

Human Immunodeficiency Virus/Hepatitis C Virus (HCV) Co-infected Patients With Cirrhosis Are No Longer at Higher Risk for Hepatocellular Carcinoma or End-Stage Liver Disease as Compared to HCV Mono-infected Patients.

It is widely accepted that human immunodeficiency virus (HIV) infection is a risk factor for increased severity of hepatitis C virus (HCV) liver disease. However, owing to better efficacy and safety of combination antiretroviral therapy (cART), and increased access to HCV therapy, whether this condition remains true is still unknown. Overall, 1,253 HCV mono-infected patients and 175 HIV/HCV co-infected patients with cirrhosis, included in two prospective French national cohorts (ANRS CO12 CirVir and CO13 HEPAVIH), were studied. Cirrhosis was compensated (Child-Pugh A), without past history of complication, and assessed on liver biopsy. Incidences of liver decompensation (LD), hepatocellular carcinoma (HCC), and death according to HIV status were calculated by a Fine-Gray model adjusted for age. Propensity score matching was also performed to minimize confounding by baseline characteristics. At baseline, HIV/HCV patients were younger (47.5 vs. 56.0 years; P < 0.001), more frequently males (77.1% vs. 62.3%; P < 0.001), and had at baseline and at end of follow-up similar rates of HCV eradication than HCV mono-infected patients. A total of 80.4% of HIV/HCV patients had an undetectable HIV viral load. After adjustment for age, 5-year cumulative incidences of HCC and decompensation were similar in HIV/HCV and HCV patients (8.5% vs. 13.2%, P = 0.12 and 12.8% vs. 15.6%, P = 0.40, respectively). Overall mortality adjusted for age was higher in HIV/HCV co-infected patients (subhazard ratio [SHR] = 1.88; 95% confidence interval [CI], 1.15-3.06; P = 0.011). Factors associated with LD and HCC were age, absence of sustained virological response, and severity of cirrhosis, but not HIV status. Using a propensity score matching 95 patients of each group according to baseline features, similar results were observed. Conclusion: In HCV-infected patients with cirrhosis, HIV co-infection was no longer associated with higher risks of HCC and hepatic decompensation. Increased mortality, however, persisted, attributed to extrahepatic conditions.

Incidence of Hepatocellular Carcinoma After Direct Antiviral Therapy for HCV in Patients With Cirrhosis Included in Surveillance Programs.

BACKGROUND & AIMS: Retrospective studies have found an unexpectedly high incidence of hepatocellular carcinoma (HCC) among patients with hepatitis C virus (HCV)-associated cirrhosis who received direct-acting antiviral (DAA) agents. We analyzed data from the ANRS CO12 CirVir cohort to compare the incidence of HCC in patients with cirrhosis who received DAA therapy vs patients treated with interferon (IFN). METHODS: Data were collected from 1270 patients with compensated biopsy-proven HCV-associated cirrhosis recruited from 2006 through 2012 at 35 centers in France. For descriptive purpose, patients were classified as follows: patients who received DAA treatment (DAA group, n = 336), patients who achieved a sustained virologic response (SVR) following an IFN-based regimen (SVR-IFN group, n = 495), or patients who never received DAA treatment and never had an SVR following IFN therapy (non-SVR group, n = 439). The patients were included in HCC surveillance programs based on ultrasound examination every 6 months, and clinical and biological data were recorded. To account for confounding by indication due to differences in patient characteristics at treatment initiation, we constructed a time-dependent Cox regression model weighted by the inverse probability of treatment and censoring (IPTCW) to assess the treatment effects of DAA on time until HCC. RESULTS: Compared with patients in the SVR-IFN group, patients in the DAA group were older, higher proportions had diabetes or portal hypertension, and liver function was more severely impaired. The crude 3-year cumulative incidences of HCC were 5.9% in the DAA group, 3.1% in the SVR-IFN group, and 12.7% in the non-SVR group (overall P < .001; unadjusted hazard ratio [HR] for HCC 2.03; 95% confidence interval [CI] 1.07-3.84; P = .030 for the DAA group vs the SVR-IFN group). HCC characteristics were similar among groups. Among patients with HCC, the DAA group received less-frequent HCC screening than the other 2 groups (P = .002). After Cox analyses weighted by the IPTCW, we found no statistically significant increase in risk of HCC associated with DAA use (HR 0.89; 95% CI 0.46-1.73; P = .73). CONCLUSIONS: Analysis of data from the ANRS CO12 CirVir cohort reveals that the apparent increase in HCC incidence observed in patients with cirrhosis treated with DAAs compared with patients who achieved SVR following an IFN therapy can be explained by patient characteristics (age, diabetes, reduced liver function) and lower screening intensity.

Compliance With Hepatocellular Carcinoma Surveillance Guidelines Associated With Increased Lead-Time Adjusted Survival of Patients With Compensated Viral Cirrhosis: A Multi-Center Cohort Study.

BACKGROUND & AIMS: Semi-annual surveillance for hepatocellular carcinoma (HCC) is recommended for patients with cirrhosis. We aimed to determine how compliance with HCC surveillance guidelines affects survival times of patients with hepatitis C virus- or hepatitis B virus-associated compensated cirrhosis who developed HCC. METHODS: We collected data from the prospective ANRS CO12 CirVir study, from March 2006 through June 2012, on 1671 patients with biopsy-proven viral cirrhosis and no previous liver complications who were undergoing surveillance for HCC at 35 centers in France. Only 216 patients who developed HCC during the follow-up period were included in the analysis. Patients were considered to be compliant with surveillance guidelines if the time between their last surveillance image evaluation and diagnosis of HCC were fewer than 7 months and noncompliant if this time was 7 months or longer. RESULTS: HCC was detected in 216 patients, at a median follow-up time of 59.7 months. Of these patients, 140 (80.5%) were Barcelona Clinic Liver Cancer stage 0/A, 135 (69.9%) received first-line curative treatment (15 underwent transplantation, 29 underwent resection, 89 received percutaneous ablation, and 2 received resection and percutaneous ablation), and 129 (60.0%) were compliant with surveillance guidelines. Seventy-nine of the patients with HCC died; 49 deaths were associated with tumor progression. After lead-time adjustment, overall survival (OS) time was longer in patients compliant with surveillance guidelines (median OS time, 53.2 months) than noncompliant patients (median OS time, 25.4 months) (P = .0107); this difference remained significant even when we changed lead time assumptions. In multivariate analysis adjusted for a propensity score, compliance with HCC surveillance guidelines was associated with low tumor burden, allocation of curative treatment, and increased OS time compared with noncompliance (hazard ratio for OS, 2.19; 95% confidence interval, 1.16-4.14; P = .0150). CONCLUSIONS: In an analysis of data from the ANRS CO12 CirVir cohort, we associated compliance with HCC surveillance guidelines (fewer than 7 months between image evaluations) with early diagnosis, allocation of curative treatment, and longer adjusted OS of patients with hepatitis C virus- or hepatitis B virus-associated compensated cirrhosis and a diagnosis of HCC.

Cascade of care for migrants tested Hepatitis C antibodies positive in France through a systematic screening programme: The PRECAVIR study.

Migration of people from HCV endemic countries is a public health issue for the French healthcare system. The PRECAVIR study focused on migrant patients and provides a multidisciplinary, patient-centred approach to treat chronic HCV-infected migrants through a systematic screening programme. Between 2007 and 2017, 101 (2.98%) out of 3386 consecutive adult migrants attending two primary healthcare settings in Créteil, France, tested positive for HCV. The median age was 44.5 years old, and 55% were women. Patients were mainly from sub-Saharan Africa, Eastern Europe and Asia. Seventy-four patients were undocumented migrants, and 25 were asylum seekers. Eighty-four (83%) patients were unaware of their serological status. All patients were offered referral to a specialist in the same setting. HCV RNA testing was performed in 88 (87%) of the patients who tested anti-HCV positive. Forty-nine (57%) were chronically infected, while 39 (43%) had an undetectable viral load. All patients were treatment-naïve. More than half of patients had access to treatment. Before 2014, thirteen patients were treated with pegylated interferon and ribavirin, and an SVR was achieved in 8 (61.5%) of them. By 2017, 17 patients had begun oral, direct-acting antiviral treatment. An SVR was achieved in 16 of 17 patients (93%). However, all patients not initially eligible for treatment were lost to follow-up. This study showed the effectiveness of a coordinated care network when anti-HCV testing, linkage to care and treatment are organized for a migrant population in the same setting as long as universal treatment makes a test and treat policy possible.

Primary resistance of hepatitis B virus to nucleoside and nucleotide analogues.

Nucleoside and nucleotide analogues (NUCs) targeting hepatitis B virus are capable of selecting resistant viruses upon long-term administration as monotherapies. The prevalence of resistance-associated substitutions (RASs) and fitness-associated substitutions at baseline of NUC therapy and their impact on treatment responses remain unknown. A total of 232 treatment-naïve patients chronically infected with hepatitis B virus (HBV) consecutively referred for the first time to one of French reference centres were included. The nearly full-length HBV reverse transcriptase was sequenced by means of deep sequencing, and the sequences were analysed. RASs were detected in 25% of treatment-naïve patients, generally representing low proportions of the viral quasispecies. All amino acid positions known to be associated with HBV resistance to currently approved NUCs or with increased fitness of resistant variants were affected, except position 80. RASs at positions involved in lamivudine, telbivudine and adefovir resistance were the most frequently detected. All patients with RASs detectable by next-generation sequencing at baseline who were treatment-eligible and treated with currently recommended drugs achieved a virological response. The presence of pre-existing HBV RASs has no impact on the outcome of therapy if potent drugs with a high barrier to resistance are used.

Non-virological factors are drivers of hepatocellular carcinoma in virosuppressed hepatitis B cirrhosis: Results of ANRS CO12 CirVir cohort.

Worldwide, hepatocellular carcinoma (HCC) occurs mainly in Asian patients with hepatitis B virus (HBV) infection. This study aimed to decipher the environmental and virological factors associated with HCC occurrence and validate risk scoring systems in a French multicentre prospective cohort of HBV cirrhotic patients. Patients with biopsy-proven Child-Pugh A viral cirrhosis included in the ANRS CO12 CirVir cohort who were HBsAg(+) without hepatitis C coinfection were selected for: (a) interview through a standardized questionnaire reporting coffee consumption and HCC familial history; (b) HBsAg quantification using baseline and sequential 2-year frozen sera; (c) baseline HBV genotype determination; and (d) assessment of risk factors and applicability of HCC risk scores (Kaplan-Meier analysis, Cox models). Among 317 patients studied (261 men, median age 53 years, past or ongoing antiviral treatment 93.3% and baseline detectable HBV DNA in 88 patients), the baseline and 2-year median HBsAg levels were 810 and 463 IU/mL, respectively. After a median follow-up of 65.2 months, 27 HCC cases were diagnosed (annual incidence: 1.6%). Three factors were independently associated with HCC occurrence: age > 50 years, platelets ≤ 150 × 103 /mm3 and body mass index ≥ 30 kg/m2 . Two out of five risk scores were validated, and the most accurate was PAGE-B at 1 year. Moreover, HCC in patients without maintained virological suppression seems more aggressive and less accessible to curative treatment. In conclusion, in French patients with HBV cirrhosis mostly virally suppressed, independent HCC risk factors were host-related (age, obesity) or linked to the severity of cirrhosis (thrombopenia), and the European PAGE-B score was the most accurate risk score.

Influence of Progenitor-Derived Regeneration Markers on Hepatitis C Virus-Related Cirrhosis Outcome (ANRS CO12 CirVir Cohort).

Progenitor-derived regeneration gives rise to the aberrant expression of biliary markers such as cytokeratin 7 (K7) and epithelial cell adhesion molecule (EpCAM) in hepatocytes. We aimed to describe the expression of these molecules in patients with compensated hepatitis C virus (HCV)-related cirrhosis and to investigate its potential influence on cirrhosis complications. Among patients with Child-Pugh A uncomplicated HCV-related cirrhosis enrolled in the prospective ANRS CO12 CirVir cohort, we selected individuals with a liver biopsy collected within 2 years before inclusion in the study. K7 and EpCAM immunostaining identified intermediate hepatobiliary cells. The influence of biliary marker expres-sion in hepatocytes on decompensation events and the occurrence of hepatocellular carcinoma (HCC) was studied using a multivariate Cox proportional hazards regression model. Among the 337 patients eligible for the study (men, 67%; median age, 52 years), 198 (58.8%) had biopsies with K7-positive hepatocytes including extensive staining in 40 (11.9%) and 203 had EpCAM-positive hepatocytes (60.6%). During follow-up (median, 54.2 months), 47 patients (14%) experienced a decompensation event, and HCC was diagnosed in 37 patients (11%). Extensive K7 staining was independently associated with the occurrence of a decompensation event (hazard ratio [HR], 3.00; 95% confidence interval [CI], 1.30-6.89; P = 0.010). EpCAM expression was independently associated with HCC occurrence (HR, 2.37; 95% CI, 1.07-5.23; P =0.033) along with age and a low prothrombin ratio. CONCLUSION: Progenitor-derived regeneration depicted by K7 and EpCAM immunostaining of hepatocytes in liver biopsies of patients with compensated HCV-related cirrhosis marks a cirrhosis stage more prone to develop complications.

Extrahepatic cancers are the leading cause of death in patients achieving hepatitis B virus control or hepatitis C virus eradication.

Data on extrahepatic cancers (EHCs) in compensated viral cirrhosis are limited. The objective of the prospective multicenter Agence Nationale de Recherche sur le SIDA et les Hépatites virales CO12 CirVir cohort was to assess the occurrence of all clinical events in patients with compensated viral cirrhosis, including all types of cancer. Patients with the following inclusion criteria were enrolled in 35 French centers: (1) biopsy-proven hepatitis B virus (HBV) or hepatitis C virus (HCV) cirrhosis, (2) Child-Pugh A, or (3) absence of previous liver complications including primary liver cancer (PLC). Patients were followed up prospectively every 6 months. The standardized mortality ratio (SMR) was calculated according to age and gender using 5-year periods. The impact of sustained viral response (SVR) in HCV patients and maintained viral suppression in HBV patients were assessed using time-dependent analysis. A total of 1,671 patients were enrolled between 2006 and 2012 (median age, 54.9 years; men, 67.3%; HCV, 1,323; HBV, 317; HCV-HBV, 31). Metabolic features and excessive alcohol and tobacco consumption were recorded in 15.2%, 36.4%, and 56.4% of cases, respectively. After a median follow-up of 59.7 months, 227 PLCs were diagnosed (5-year cumulative incidence [CumI] 13.4%) and 93 patients developed EHC (14 patients with lymphoid or related tissue cancer and 79 with solid tissue cancer; 5-year EHC CumI, 5.9%). Compared to the general French population, patients were younger at cancer diagnosis, with significantly higher risk of EHC in HCV patients (SMR, 1.31; 95 confidence interval [CI], 1.04-1.64; P = 0.017) and after SVR (SMR = 1.57; 95% CI, 1.08-2.22; P = 0.013). EHC was the fourth leading cause of death in the whole cohort and the first in patients with viral control/eradication. CONCLUSION: Compared to the general French population, HCV cirrhosis is associated with a higher risk of EHC and the first cause of death in patients with viral cirrhosis who achieve virological control/eradication.

Prognostic factors of survival in HIV/HCV co-infected patients with hepatocellular carcinoma: The CARCINOVIC Cohort.

BACKGROUND & AIMS: HIV/HCV co-infected patients with hepatocellular carcinoma (HCC) have poorer survival than HCV mono-infected patients. We aimed to evaluate the prognostic factors for survival. METHODS: From 2006 to 2013, 55 incident HCCs among HIV+/HCV+ patients, from three ANRS cohorts, were compared with 181 HCCs in HIV-/HCV+ patients from the ANRS Cirvir cohort. RESULTS: HIV+/HCV+ patients were younger (50 years [IQR: 47-53] vs 62 [54-70], P < 0.001), male (89% vs 63%, P < 0.001) than HIV-/HCV+ patients. At HCC diagnosis, both groups had a majority of non-responders to anti-HCV-therapy, and HIV+/HCV+ patients had more frequently known a previous cirrhosis decompensation (31% vs 14%, P = 0.005). At diagnostic imaging, there were more infiltrative forms of HCC in HIV+/HCV+ group (24% vs 14%, P < 0.001), associated with tumour portal thrombosis in 29%. During a median follow-up period of 11.96 [5.51-27] months since HCC diagnosis, a majority of palliative treatments were decided in HIV+/HCV+ patients (51% vs 19%, P < 0.001). The 1 and 2-year crude survival rates were 61% versus 78% and 47% versus 63%, P = 0.003 respectively. In a Cox model multivariate analysis adjusted for the cohort, age and sex, the most important prognostic factor for survival was the infiltrative form of the tumour (aRR: 8.10 [4.17-15.75], P < 0.001). CONCLUSIONS: The radiological aggressiveness of the tumour is the best prognostic factor associated with poorer survival of HCC in HIV+/HCV+ patients. High α-foetoprotein level and decompensated cirrhosis are other ones. This justifies a particular attention to the detection and the management of small nodules in this high-risk population.

Assessing the cost-effectiveness of hepatitis C screening strategies in France.

BACKGROUND & AIMS: In Europe, hepatitis C virus (HCV) screening still targets people at high risk of infection. We aim to determine the cost-effectiveness of expanded HCV screening in France. METHODS: A Markov model simulated chronic hepatitis C (CHC) prevalence, incidence of events, quality-adjusted life years (QALYs), costs and incremental cost-effectiveness ratio (ICER) in the French general population, aged 18 to 80 years, undiagnosed for CHC for different strategies: S1 = current strategy targeting the at risk population; S2 = S1 and all men between 18 and 59 years; S3 = S1 and all individuals between 40 and 59 years; S4 = S1 and all individuals between 40 and 80 years; S5 = all individuals between 18 and 80 years (universal screening). Once CHC was diagnosed, treatment was initiated either to patients with fibrosis stage ≥F2 or regardless of fibrosis. Data were extracted from published literature, a national prevalence survey, and a previously published mathematical model. ICER were interpreted based on one or three times French GDP per capita (€32,800). RESULTS: Universal screening led to the lowest prevalence of CHC and incidence of events, regardless of treatment initiation. When considering treatment initiation to patients with fibrosis ≥F2, targeting all people aged 40-80 was the only cost-effective strategy at both thresholds (€26,100/QALY). When we considered treatment for all, although universal screening of all individuals aged 18-80 is associated with the highest costs, it is more effective than targeting all people aged 40-80, and cost-effective at both thresholds (€31,100/QALY). CONCLUSIONS: In France, universal screening is the most effective screening strategy for HCV. Universal screening is cost-effective when treatment is initiated regardless of fibrosis stage. From an individual and especially from a societal perspective of HCV eradication, this strategy should be implemented. LAY SUMMARY: In the context of highly effective and well tolerated therapies for hepatitis C virus that are now recommended for all patients, a reassessment of hepatitis C screening strategies is needed. An effectiveness and cost-effectiveness study of different strategies targeting either the at-risk population, specific ages or all individuals was performed. In France, universal screening is the most effective strategy and is cost-effective when treatment is initiated regardless of fibrosis stage. From an individual and especially from a societal perspective of hepatitis C virus eradication, this strategy should be implemented.

Eradication of Hepatitis C Virus Infection in Patients With Cirrhosis Reduces Risk of Liver and Non-Liver Complications.

BACKGROUND & AIMS: We performed a prospective study to investigate the effects of a sustained viral response (SVR) on outcomes of patients with hepatitis C virus (HCV) infection and compensated cirrhosis. METHODS: We collected data from 1323 patients included in the prospective Agence Nationale pour la Recherche sur le SIDA et les hépatites virales (ANRS) viral cirrhosis (CirVir) cohort, recruited from 35 clinical centers in France from 2006 through 2012. All patients had HCV infection and biopsy-proven cirrhosis, were Child-Pugh class A, and had no prior liver complications. All patients received anti-HCV treatment before or after inclusion (with interferon then with direct antiviral agents) and underwent an ultrasound examination every 6 months, as well as endoscopic evaluations. SVR was considered as a time-dependent covariate; its effect on outcome was assessed by the Cox proportional hazard regression method. We used a propensity score to minimize confounding by indication of treatment and capacity to achieve SVR. RESULTS: After a median follow-up period of 58.2 months, 668 patients (50.5%) achieved SVR. SVR was associated with a decreased incidence of hepatocellular carcinoma (hazard ratio [HR] compared with patients without an SVR, 0.29; 95% confidence interval [CI], 0.19-0.43; P < .001) and hepatic decompensation (HR, 0.26; 95% CI, 0.17-0.39; P < .001). Patients with SVRs also had a lower risk of cardiovascular events (HR, 0.42; 95% CI, 0.25-0.69; P = .001) and bacterial infections (HR, 0.44; 95% CI, 0.29-0.68; P < .001). Metabolic features were associated with a higher risk of hepatocellular carcinoma in patients with SVRs, but not in patients with viremia. SVR affected overall mortality (HR, 0.27 compared with patients without SVR; 95% CI, 0.18-0.42; P < .001) and death from liver-related and non-liver-related causes. Similar results were obtained in a propensity score-matched population. CONCLUSIONS: We confirmed a reduction in critical events, liver-related or not, in a prospective study of patients with HCV infection and compensated cirrhosis included in the CirVir cohort who achieved an SVR. We found an SVR to reduce overall mortality and risk of death from liver-related and non-liver-related causes. A longer follow-up evaluation is required to accurately describe and assess specific risk factors for complications in this population.

Prognostic value of viral eradication for major adverse cardiovascular events in hepatitis C cirrhotic patients.

BACKGROUND: The objective was to examine the role of a sustained virological response (SVR) on major adverse cardiovascular events (MACEs) in patients with compensated hepatitis C virus (HCV) cirrhosis. METHODS: Patients with the following criteria were enrolled in 35 French centers: (1) biopsy-proven HCV cirrhosis; (2) Child-Pugh A; (3) positive viremia; and (4) no prior liver complication, and then prospectively followed. All patients received HCV treatment after inclusion. MACEs included stroke, myocardial infarction, ischemic heart disease, heart failure, peripheral arterial disease, cardiac arrest, and cardiovascular death. SVR, defined as negative viremia 12 weeks posttreatment, was considered as a time-dependent covariate, and its effect on MACE occurrence was assessed. The median follow up was 57.5 months, ending in December 2015. RESULTS: Sixty-two of 878 (7.1%) patients presented a total of 79 MACEs. The main predictive baseline factors of MACEs were Asian ethnic origin, history of MACEs, arterial hypertension, diabetes mellitus, current smoking, low serum albumin level, high total bilirubin level, and low platelet count. In multivariate analysis, SVR was associated with a decreased risk of MACEs (hazard ratio=0.35, 95% CI 0.09-0.97, P=.044), whereas Asian ethnic origin, arterial hypertension, smoking, and low serum albumin level remained predictive of MACE occurrence. The 5-year survival rate was 60.1% versus 87.5% in patients who did versus those who did not present a MACE (P<.001). CONCLUSIONS: In patients with compensated HCV-related cirrhosis, Asian ethnic origin, arterial hypertension, smoking, and low serum albumin are independent predictive factors of cardiovascular events, whereas an SVR is associated with a decreased rate of cardiovascular events.

Bacterial infection in compensated viral cirrhosis impairs 5-year survival (ANRS CO12 CirVir prospective cohort).

OBJECTIVE: To assess incidence and prognostic significance of bacterial infections (BIs) occurring in compensated viral cirrhosis. DESIGN: This prospective study involved 35 French centres. Inclusion criteria were biopsy-proven HCV or HBV cirrhosis, Child-Pugh A and no previous hepatic complications. Cumulative incidence (CumI) of events was estimated in a competing risks framework. RESULTS: 1672 patients were enrolled (HCV 1323, HBV 318, HCV-HBV 31). During a median follow-up of 43 months, 234 BIs occurred in 171 patients (5 year CumI: 12.9%), among whom 14.6% had septic shock. Main localisations included the urinary tract (27.4%), lung (25.2%) and peritoneum (10.7%) (other, 86 (36.7%)). Most BIs occurred as a first event prior to liver decompensation (n=140, 81.8%) and were community-acquired (CA, 84.2%). The risk of BI was higher in patients with HCV than in patients with HBV (5 year CumI: 15.2% vs 5.5%, p=0.0008). Digestive localisation, concomitant interferon-based treatment, isolation of resistant bacteria and non-CA BIs were associated with lowest probability of resolution. The occurrence of a first BI impaired survival in patients infected with HCV (5 year survival: 60.2% vs 90.4%, p<0.001) and patients infected with HBV (5 year survival: 69.2% vs 97.6%, p<0.001). BIs represented the third cause of death (14.1%) after liver failure and liver cancer. BI risk factors comprised older age, lower albumin, proton pump inhibitor intake and absence of virological eradication/control. CONCLUSION: BI mostly occurs as a first complication and represents a turning point in the course of compensated viral cirrhosis. Its occurrence impacts long-term prognosis and may define a subgroup of patients in whom adaptation of management is warranted.

Sofosbuvir-Daclatasvir-Simeprevir Plus Ribavirin in Direct-Acting Antiviral-Experienced Patients With Hepatitis C.

We assessed the broadly used, off-label combination of sofosbuvir, daclatasvir, simeprevir, and ribavirin in direct-acting antiviral-experienced patients, as recommended in current guidelines despite scarce data. After 24 weeks' treatment, sustained virological response 12 weeks after the end of treatment was achieved in 6 patients (60%). Two cirrhotic patients relapsed and 2 discontinued treatment due to serious adverse events.

Validation of the AFP model as a predictor of HCC recurrence in patients with viral hepatitis-related cirrhosis who had received a liver transplant for HCC.

BACKGROUND & AIMS: The AFP model was shown to be superior to the Milan criteria for predicting hepatocellular carcinoma (HCC) recurrence after liver transplantation in a French population. Our aim was to test the AFP model in a non-French, post-hepatitic cirrhosis-based population of HCC candidates. METHODS: 574 patients transplanted for HCC in four Italian centers were studied. AFP score was assessed at the last evaluation before liver transplantation (LT). Probabilities of recurrence and survival were estimated by the log-rank test or competing risk analysis and compared according to the AFP model. RESULTS: 24.7% patients were beyond Milan criteria. HCC complicated hepatitis C virus (HCV) and hepatitis B virus (HBV) cirrhosis in 58.7% and 24% of the cases, respectively. Five-year probabilities of recurrence differed according to AFP score ⩽2 vs. >2 in the whole population (13.2±1.8% vs. 49.8±8.7%, p<0.001, HR=4.98), in patients within Milan criteria (12.8±2.0% vs. 32.4±12.1%, p=0.009, HR=3.51), beyond Milan criteria (14.9±4.2% vs. 58.9±11.5%, p<0.001, HR=4.26), HCV patients (14.9±2.5% vs. 67.6±14.7%, p<0.001, HR=6.56) and HBV patients (11.6±3.4% vs. 34.3±12.5%, p=0.012, HR=3.49). By net reclassification improvement analysis AFP score significantly improved prediction of non-recurrence compared to Milan criteria. Overall five-year survival rates according to AFP score ⩽2 or >2 were 71.7±2.2% vs. 42.2±8.3% (p<0.001, HR=2.14). CONCLUSIONS: The AFP model identifies HCC candidates at low risk of recurrence, otherwise excluded by Milan criteria in a population with a predominance of post-hepatitic-related HCC. The AFP score can be proposed for selection of HCC candidates in programs with a high proportion of viral/HCV-related cirrhosis. LAY SUMMARY: Selection criteria for liver transplantation of patients affected with hepatocellular carcinoma (HCC) are based on the Milan criteria, which have been shown to be too restrictive, precluding access to liver transplantation for some patients who might be cured by this operation. Recently, a French group of researchers developed a new selection model called the AFP model, or AFP score, allowing some patients with HCC not meeting Milan criteria to be transplanted with excellent results. In the present work, the AFP score was tested in a population of non-French patients transplanted for HCC occurring mainly on post-hepatitic (HCV or HBV) cirrhosis. The results confirm that in this specific population, as in the original French population of patients, the AFP model better selects patients with HCC eligible for transplantation, compared to Milan criteria. We conclude that the AFP score, which has been officially adopted by the French organization for Organ Sharing for HCC patients, can also be implemented in countries with an important burden of HCC occurring on post-hepatitic cirrhosis.
