RESUMEN

BACKGROUND & AIMS: Liver stiffness measurement by transient elastography (TE) is a promising method for staging fibrosis in alcohol-related liver disease, but uncertainties remain regarding the influence of alcohol consumption and thus the ideal timing for TE performance. We evaluated the performance of TE compared with liver biopsy to exclude compensated advanced chronic liver disease (cACLD) in patients hospitalized for alcohol detoxification. METHODS: Patients were recruited prospectively at 6 in-patient addiction centers in France. Eligible patients had increased aspartate aminotransferase levels, and no history or signs of overt cirrhosis. TE, histology, and biochemistry measurements were obtained within a median of 6 days after alcohol withdrawal. TE and biochemistry were repeated 1 and 2 months later. RESULTS: The study included 259 patients for per-protocol analysis, of whom 45 (17%) had cACLD. TE identified patients with high accuracy at inclusion and at the 1- and 2-month follow-up evaluation, with area under the curve values of 0.96 (95% CIs, 0.94-0.99), 0.96 (95% CIs, 0.92-0.99), and 0.93 (95% CIs, 0.85-1.00), respectively. In 84% of patients, cACLD was ruled out when liver stiffness was less than 10 kPa (negative predictive value, 99% (95% CIs, 98%-100%)) or ruled in when greater than 25 kPa (positive predictive value, 93% (95% CI, 83%-102%)). Algorithms based on aminotransferase levels and/or bilirubin did not add to the diagnostic performance of TE in this period. Among patients with initial liver stiffness of 10 to 25 kPa, more than half of those with no cACLD showed liver stiffness of less than 10 at 1- and 2-month follow-up testing. CONCLUSIONS: TE performed during the first 2 months after alcohol cessation is an excellent method for excluding alcohol-related cACLD. CLINICAL TRIAL NUMBER: NCT01789008.

RESUMEN

BACKGROUND AND AIMS: Non-O blood group promotes deep vein thrombosis and liver fibrosis in both general population and hepatitis C. We aimed to evaluate the influence of Non-O group on the outcome of Child-Pugh A cirrhotic patients. METHODS: We used two prospective cohorts of Child-Pugh A cirrhosis due to either alcohol or viral hepatitis. Primary end point was the cumulated incidence of 'Decompensation' at 3 years, defined as the occurrence of ascites , hydrothorax, encephalopathy, gastrointestinal bleeding related to portal hypertension, or bilirubin >45 µmol/L. Secondary end points were the cumulated incidences of (1) 'Disease Progression' including a « decompensation¼ or « the occurrence of one or more parameters ¼ among: prothrombin time (PT) <45%, albumin <28 g/L, Child-Pugh worsening (B or C vs A or B, C vs B), hepatorenal syndrome, and hepato-pulmonary syndrome, (2) other events such as non-malignant portal vein thrombosis (nmPVT), and (3) overall survival. RESULTS: Patients (n = 1789; 59.9% Non-O group; 40.1% group O) were followed during a median of 65.4 months. At 3 years cumulated incidence of Decompensation was 8.3% in Non-O group and 7.2% in group O (P = .27). Cumulated incidence of Disease Progression was 20.7% in Non-O group and 18.9% in group O (P = .26). Cumulated incidence of nmPVT was 2.7% in Non-O group and 2.8% in group O (P = .05). At 3 years overall survival was 92.4% in Non-O group and 93.4% in group O (P = 1). CONCLUSION: Non-O group does not influence disease outcome in Child-Pugh A cirrhotic patients. Clinicals trial number NCT03342170.

RESUMEN

BACKGROUND: Despite an effective vaccine, hepatitis B remains a major global health problem due to its significant morbidity and mortality. Vaccination in immunosuppressed patients such as those treated for an inflammatory bowel disease (IBD) can be less effective. This case describes an uncommon original diagnosis of an acute hepatitis B infection occurring in a vaccinated but immunocompromised IBD patient under long-term infliximab treatment. A low anti-HBs titer and the presence of HBsAg escape mutations are possible hypotheses to explain this unexpected infection. CASE PRESENTATION: A 28-year-old Caucasian male, regularly followed-up for a Crohn's disease treated by infliximab, was regularly screened for sexually transmissible infections because of at-risk behaviors. Despite a correct immunization scheme against hepatitis B virus (HBV), an active HBV infection was diagnosed during one of those screenings. Retrospective testing of a sample collected 6 months earlier was in favor of an evolution from an acute hepatitis B toward a chronic hepatitis B. The patient has always had a low anti-HBs antibody levels (near the threshold of 10 IU/L) possibly explaining his infection. In addition, HBV sequencing revealed a genotype A2 HBV strain, carrying the sD144A substitution on the S protein, known as a potential immune escape variant. Dual therapy combining tenofovir disoproxil fumarate and emtricitabine, active against HBV but also efficient as an HIV pre-exposure prophylaxis, was initiated. Ten months after treatment initiation, all surrogate biochemical and virological endpoints for HBV functional cure were achieved. Treatment and periodical monitoring are being maintained. CONCLUSION: Emphasis should be placed on HBV screening, vaccination and regular monitoring of patients under long-term immunosuppressive therapy, particularly those with at-risk behaviors.

RESUMEN

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 < 0.0001), liver-related mortality (HR 0.40, 95% CI 0.17-0.96, p = 0.04), non-liver-related mortality (HR 0.17, 95% CI 0.06-0.49, p = 0.001), liver transplantation (HR 0.17, 95% CI 0.05-0.54, p = 0.003), and hepatocellular carcinoma (HR 0.52, 95% CI 0.29-0.93, p = 0.03). CONCLUSION: Treatment with direct antiviral agents is associated with reduced risk for mortality. The sustained virological response was 88%. Thus, direct antiviral agents treatment should be considered for any patient with HCV-related decompensated cirrhosis. TRIAL REGISTRATION:  ClinicalTrials.gov registry number: NCT01953458.

RESUMEN

BACKGROUND: Treatment of hepatitis C virus (HCV) has been dramatically improved with the introduction of direct-acting antiviral agents (DAAs). Universal access to pangenotypic DAAs was provided in France from 2017, expanding the type of patients treated. Real-world studies are important to confirm effectiveness and safety in clinical practice, particularly in vulnerable populations. AIMS: To assess real-world effectiveness and safety of sofosbuvir-based therapy in adults with chronic HCV infection before and after universal access to DAAs in France. METHODS: This multicenter, non-interventional, prospective study assessed the effectiveness, safety, patient-reported outcomes and adherence with sofosbuvir-based regimens from October 2015 to July 2016 (Period 1: sofosbuvir-based therapy excluding sofosbuvir/velpatasvir) and from October 2017 to July 2018 (Period 2: pangenotypic sofosbuvir/velpatasvir-based therapy). RESULTS: Baseline data were documented for 1029 patients. Overall, 797 (77%) had sustained virologic response data available ≥ 9 weeks after treatment completion. Per protocol response was high (97%) irrespective of age, alcohol consumption, recreational drug use, or HIV/HCV coinfection. Adverse events occurred in approximately 25% of patients with the majority experiencing Grade 1 or 2 events. Sofosbuvir-based regimens improved health-related quality of life from baseline to end of treatment in patients with data at all timepoints. Overall, 99% of patients reported total or almost total adherence to therapy. CONCLUSIONS: Sofosbuvir-based therapy, including pangenotypic sofosbuvir/velpatasvir, is effective for the treatment of HCV in real-world clinical practice. This is an important step towards HCV elimination.

RESUMEN

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.

RESUMEN

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.

RESUMEN

BACKGROUND: Although direct-acting antivirals have been used extensively to treat patients with chronic hepatitis C virus (HCV) infection, their clinical effectiveness has not been well reported. We compared the incidence of death, hepatocellular carcinoma, and decompensated cirrhosis between patients treated with direct-acting antivirals and those untreated, in the French ANRS CO22 Hepather cohort. METHODS: We did a prospective study in adult patients with chronic HCV infection enrolled from 32 expert hepatology centres in France. We excluded patients with chronic hepatitis B, those with a history of decompensated cirrhosis, hepatocellular carcinoma, or liver transplantation, and patients who were treated with interferon-ribavirin with or without first-generation protease inhibitors. Co-primary study outcomes were incidence of all-cause mortality, hepatocellular carcinoma, and decompensated cirrhosis. The association between direct-acting antivirals and these outcomes was quantified using time-dependent Cox proportional hazards models. This study is registered with ClinicalTrials.gov, number NCT01953458. FINDINGS: Between Aug 6, 2012, and Dec 31, 2015, 10 166 patients were eligible for the study. 9895 (97%) patients had available follow-up information and were included in analyses. Median follow-up was 33·4 months (IQR 24·0-40·7). Treatment with direct-acting antivirals was initiated during follow-up in 7344 patients, and 2551 patients remained untreated at the final follow-up visit. During follow-up, 218 patients died (129 treated, 89 untreated), 258 reported hepatocellular carcinoma (187 treated, 71 untreated), and 106 had decompensated cirrhosis (74 treated, 32 untreated). Exposure to direct-acting antivirals was associated with increased risk for hepatocellular carcinoma (unadjusted hazard ratio [HR] 2·77, 95% CI 2·07-3·71) and decompensated cirrhosis (3·83, 2·29-6·42). After adjustment for variables (age, sex, body-mass index, geographical origin, infection route, fibrosis score, HCV treatment-naive, HCV genotype, alcohol consumption, diabetes, arterial hypertension, biological variables, and model for end-stage liver disease score in patients with cirrhosis), exposure to direct-acting antivirals was associated with a decrease in all-cause mortality (adjusted HR 0·48, 95% CI 0·33-0·70) and hepatocellular carcinoma (0·66, 0·46-0·93), and was not associated with decompensated cirrhosis (1·14, 0·57-2·27). INTERPRETATION: Treatment with direct-acting antivirals is associated with reduced risk for mortality and hepatocellular carcinoma and should be considered in all patients with chronic HCV infection.

RESUMEN

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.

RESUMEN

BACKGROUND & AIMS: Genetic hemochromatosis is mainly related to the homozygous p.Cys282Tyr (C282Y) mutation in the HFE gene, which causes hepcidin deficiency. Its low penetrance suggests the involvement of cofactors that modulate its expression. We aimed to describe the evolution of disease presentation and of non-genetic factors liable to impact hepcidin production in the long term. METHODS: Clinical symptoms, markers of iron load, and risk factors according to the year of diagnosis were recorded over 30 years in a cohort of adult C282Y homozygotes. A total of 2,050 patients (1,460 probands [804 males and 656 females] and 542 relatives [244 males and 346 females]) were studied. RESULTS: Over time: (i) the proband-to-relative ratio remained roughly stable; (ii) the gender ratio tended towards equilibrium among probands; (iii) age at diagnosis did not change among males and increased among females; (iv) the frequency of diabetes and hepatic fibrosis steadily decreased while that of chronic fatigue and distal joint symptoms remained stable; (v) transferrin saturation, serum ferritin and the amount of iron removed decreased; and (vi) the prevalence of excessive alcohol consumption decreased while that of patients who were overweight increased. Tobacco smoking was associated with increased transferrin saturation. CONCLUSION: Genetic testing did not alter the age at diagnosis, which contrasts with the dramatic decrease in iron load in both genders. Tobacco smoking could be involved in the extent of iron loading. Besides HFE testing, which enables the diagnosis of minor forms of the disease, the reduction of alcohol consumption and the increased frequency of overweight patients may have played a role in the decreased long-term iron load, as these factors are likely to improve hepcidin production. LAY SUMMARY: Genetic hemochromatosis is an inherited disorder that leads to progressive iron overload in the body. It results in chronic fatigue and in potential liver (cirrhosis), pancreas (diabetes) and joint (arthritis) damage in adulthood. The present study showed that tobacco smoking may aggravate iron loading, but that hemochromatosis has become less and less severe over the last 30 years despite patients being older at diagnosis, likely because of the protective effects of lower alcohol consumption and of increased weight in the French population.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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. TRIAL REGISTRATION: Trial registration with ClinicalTrials.gov NCT01953458 .

RESUMEN

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.

RESUMEN

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.

RESUMEN

Extrahepatic manifestations linked to hepatitis B Virus (HBV) are usually indirect consequences of immune-mediated mechanisms triggered by the virus replication. Strong evidence of brain HBV replication is missing and direct involvement of HBV in nervous system symptoms has been rarely reported. We report two cases of neurological manifestations contemporary to HBV infection. In both cases, HBV-DNA and HBsAg could be quantified in the cerebrospinal fluid (CSF) at relatively high levels. Differential quantification of HBsAg and HBV viral load both in CSF and in blood as well as phylogenic studies on HBV genomic sequences obtained from blood and CSF provided strong arguments for central nervous system viral replication in both cases. Direct causality of HBV replication in the central nervous system in these clinical situations is certainly not demonstrated but these findings could expand the list of hepatitis viruses possibly involved in neurological disorders. Further studies should be promoted to better document possible HBV replication in the brain tissues and its consequences.

RESUMEN

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.
