RESUMEN

The objective of our work was to evaluate the screening of hepatic fibrosis in primary care using the FIB-4 score, automatically calculated. When the FIB-4 was ≥ 1.3, it was defined as positive, and ELF Test was performed. FIB-4 positivity was confirmed when ELF Test was ≥ 9.8 indicating an advanced fibrosis. Among the 3427 patients included, 869 (25%) had a positive FIB-4 score, 784 (22.5%) at intermediate (FIB-4: 1.3-2.67), and 85 (2.5%) at high risk of fibrosis (FIB-4 > 2.67). 509 (59%) of the FIB-4 positive were confirmed by the ELF Test. The percentage of confirmation was significantly higher in patients over 65 years (83 vs. 57%), with FIB-4 > 2.67 (80 vs. 56%), BMI > 25 (47 vs. 37%), and diabetes (24 vs. 14%), p = 0.001). In patients without known liver disease (92%), the practitioner identified a cause of disease in 27% of cases: mainly NAFLD and alcohol. Liver fibrosis was suspected on FIB-4 in 25% of patients in primary care. The ELF Test, performed as a second-line, improves the screening of liver fibrosis, particularly for FIB-4 intermediate results. A positive FIB-4 test allows physicians to recognize a liver disease, providing an opportunity for timely intervention.Clinical trial registration: Comité de protection des personnes du sud-ouest et outre-mer SI18.00832.201865-MS04-IDRCB 2018-A01571-54.

RESUMEN

Background and Aim: The efficacy and safety profiles of elbasvir-grazoprevir (EBR/GZR) has been established in more than 10 clinical trials. However, the characteristics of patients treated in routine clinical practice may differ. The present study was therefore designed to assess the real-life effectiveness of EBR/GZR therapy in the general population and among subgroups with a high hepatitis C virus (HCV) prevalence in France. Methods: The Zephyr study was designed as a French, multicentre, prospective, observational study on EBR/GZR use and effectiveness in current practice in chronic hepatitis C patients. These results are based on data regarding the adult patients who received at least one dose of EBR/GZR between December 2017 and June 2019 in 67 French hospitals and clinics. Results: Overall, 478 patients were included. The Full Analysis Set corresponded to the 467 patients who met all the inclusion criteria and none of the exclusion criteria. Gender was balanced and the mean age was 55.7 ± 13.3 years. The patients were mainly treatment-naive (89.5%) and infected with Genotype 1b (70.4%). Among the 75 patients with HCV Gt1a genotype, 56% had HCV RNA ≥ 800,000 IU/ml. F3-F4 fibrosis stage involved 24.2% of our population. Our subgroups were distributed among 110 migrants (23.6%), 58 (15.3%) using opioid agonist treatment, including people who inject drugs, 30 (6.8%) with chronic kidney disease Stages 3-5, 9 (1.9%) with an inherited blood disorder, and 4 (0.9%) coinfected with HIV. The remaining 269 (58.7%) were included in the general population subgroup. Overall, sustained virologic response 12 weeks after the end of treatment reached 98.0% and remained consistent among genotype, HCV RNA values, fibrosis stage, and the subgroup of interest. The rate of Alcohol Use Disorders Identification Test-Consumption​​​ and Life Habit questionnaire completion was high at each visit, with data suggesting alcohol consumption decrease and an improvement in quality of life. Conclusions: Using real-world evidence data on a French population representative of HCV patients, we confirmed the results obtained during EBR/GZR development program.

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: Fibrosis-4 test (FIB-4) is one of the simplest, free of charge, noninvasive scoring tests. We aimed to prospectively measure the prevalence of liver fibrosis in adults with no previously known liver disease and who consulted a general practitioner by FIB-4 score; compare this test to an NAFLD Fibrosis Score (NFS) and Fibrometer (FM); explore the prevalence of risk factors (obesity, diabetes, alcohol, and hypertension) and reconsider a possible cause of liver disease in patients recognized as FIB-4-positive. METHODS: Over a 6-month period, 40 general practitioners (GPs) offered all their consecutive adult primary care patients with no previously known liver pathology and a liver fibrosis screening via a blood test of three scores. RESULTS: Among the consecutive 2121 patients included in the study, 39% had a BMI greater than 25 kg/m2, 13% had an alcohol consumption greater than 100 g/week, 10% had type 2 diabetes, and 29% had hypertension. The prevalence of significant liver fibrosis by FIB-4, according to age was 19.1% (95% confidence interval: 17.5-20.9%). By comparison, prevalence was 16.8% (15.0-18.5%) by the NFS and 8.2% (6.9-9.6%) by the FM. A significant relationship was observed between FIB-4 fibrosis risk stages and NFS and FM scores. GPs identified the cause of disease in 2/3 of FIB-4-positive cases, mainly nonalcoholic steatohepatitis. CONCLUSION: Liver fibrosis was suspected by FIB-4 score in 19.1% of patients with no previously known liver disease. The detection of significant fibrosis by the FIB-4 allowed the GP to suspect liver disease. The FIB-4 score that can be automatically generated should allow earlier recognition of liver disease in the general population.

RESUMEN

BACKGROUND: Lysosomal acid lipase deficiency (LALD, OMIM#278000) is a rare lysosomal disorder with an autosomal recessive inheritance. The main clinical manifestations are related to a progressive accumulation of cholesteryl esters, triglycerides or both within the lysosome in different organs such as the liver, spleen, and cardiovascular system. A wide range of clinical severity is associated with LALD including a severe very rare antenatal/neonatal/infantile phenotype named Wolman disease and a late-onset form named cholesteryl ester storage disease (CESD). METHODS: This study aimed to investigate a cohort of at-risk patients (4174) presenting with clinical or biological signs consistent with LALD using the assessment of LAL activity on dried blood spots. RESULTS: LAL activity was lower than 0.05 nmol/punch/L (cut-off: 0.12) in 19 patients including 13 CESD and 6 Wolman. Molecular study has been conducted in 17 patients and succeeded in identifying 34 mutated alleles. Fourteen unique variants have been characterized, 7 of which are novel. CONCLUSION: This study allowed to identify a series of patients and expanded the molecular spectrum knowledge of LALD. Besides, a new screening criteria grid based on the clinical/biological data from our study and the literature has been proposed in order to enhance the diagnosis rate in at risk populations.

RESUMEN

To assess the impact of HCV eradication on the outcomes of cirrhotic patients treated curatively for incidental hepatocellular carcinoma (HCC) detected during surveillance program. Data were collected on 1,323 French patients with compensated biopsy-proven HCV cirrhosis recruited in 35 centers (ANRS CO12 CirVir cohort). Sustained virologic responses (SVR) and the occurrence of HCC were recorded prospectively. During a median follow-up of 68.3 months, 218 patients developed HCC, 126 of whom underwent a curative procedure as first-line therapy (ablation = 95, resection = 31). The HCC BCLC stage was 0/A in 97.5% of patients; 74 (58.7%) never achieved SVR. During a median follow-up of 26.0 months after HCC treatment, 59 (46.8%) experienced HCC recurrence. SVR was not associated with a recurrence, whether considering final SVR status [HR = 0.77; 95% confidence interval (95% CI), 0.43-1.39; P = 0.39] or its time to achievement (prior to/after HCC occurrence; global P = 0.28). During the same timeframe, 46 patients with HCC (36.5%) died (liver failure: 41.9%, HCC progression: 37.2%, extrahepatic causes: 20.9%). Under multivariate analysis, SVR was associated with improved survival [HR = 0.21; 95% CI, 0.08-0.52; P = 0.001]. Survival benefit was explained by a lower incidence of liver decompensation and higher rates of sequential HCC re-treatment. Direct antiviral intake was not associated with a higher risk of HCC recurrence, but with improved survival (HR = 0.23; 95% CI, 0.06-0.83; P = 0.024). HCV eradication in primary or secondary prevention optimizes HCC management through preservation of liver function and improves survival, whatever the regimen. PREVENTION RELEVANCE: Liver failure is a competing risk of death in patients with HCC eligible for curative procedures. HCV eradication does not decrease risk of HCC recurrence in the first two years, but enables sequential curative HCC treatments through preservation of liver function. Direct-acting antiviral agent intake is not associated with HCC recurrence and improves survival.

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

INTRODUCTION: Hepatocholangiocarcinoma (HCC-ICC) is a rare tumor presenting the histologic characteristics of both hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC). As there is no consensus on it management, the therapeutic strategy rests on the specific treatments for HCC or ICC. Programmed cell death 1 (PD-1) inhibitors showed encouraging results in the second line treatment of HCC after sorafenib but it efficacy in HCC-ICC has never been reported. METHODS AND RESULTS: We present the case of a 72-year-old male patient treated for metastatic HCC-ICC due to a viral hepatitis C cirrhosis in progression after two lines of treatment. Tumor was characterized by a PDL-1 status of 85%. Patient received pembrolizumab at doses of 200 mg every 21 days by intravenous infusion. After one injection he was presented an immediate clinical benefit, a partial response was observed after two months of treatment and a complete response two months later. This response was maintained over time along with toxicity-free tumor control after 18 months treatment. CONCLUSION: To our knowledge, we reported for the first time the efficacy of a PD1 inhibitor treatment in a patient presenting metastatic HCC-ICC due to viral cirrhosis and overexpressing PDL-1 after failure of two lines of 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 AND AIMS: Achieving sustained virological response (SVR; cure) in hepatitis C patients using a simple regimen is key to making elimination by 2030 possible. In the largest real-world analysis to date, the effectiveness of pangenotypic, panfibrotic, single-tablet, sofosbuvir/velpatasvir (SOF/VEL) once-daily for 12 weeks was assessed in 12 clinical real-world cohorts from various geographical areas, settings and treatment practices. Factors affecting risk of not achieving SVR were assessed. METHODS: Adults treated with SOF/VEL 400/100 mg, without ribavirin, were included. All HCV patients reaching Week 12 or 24 post-treatment were assessed for SVR12/24. Factors associated with not achieving SVR12/24 for virological reasons were evaluated using logistic regression analysis. RESULTS: Overall, 5552 patients were included: 13.3% treatment-experienced; 20.7% compensated cirrhotic; 30.2% genotype 1; 29.5% genotype 2; 32.9% genotype 3; 4.7% genotype 4; 3.7% HIV coinfection; 13.4% current/former intravenous drug use. Of the 5196 patients evaluated for effectiveness, 98.9% achieved SVR12/24. High SVR12/24 rates occurred in all genotypes including genotype 3 (98.3%; 1649/1677) and in those with compensated cirrhosis (97.9; 1055/1078). Only 55 patients did not achieve SVR12/24 due to a virological reason; the only factor statistically significantly associated with an increased risk of not achieving SVR12/24 was compensated cirrhosis (P = .002). Overall, 6% (332/5552) of patients did not achieve SVR12/24 for non-virological reasons (67% lost to follow-up; 26.5% early treatment discontinuation). CONCLUSIONS: In this large cohort, representative of clinical practice, a simple 12-week regimen of SOF/VEL without ribavirin resulted in high SVR12/24 rates in diverse patient populations, even among those with compensated cirrhosis.

RESUMEN

BACKGROUND AND AIMS: Sustained off-treatment immune control is achievable in a proportion of patients with chronic hepatitis B treated with peginterferon alfa-2a. We evaluated on-treatment predictors of hepatitis B surface antigen (HBsAg) clearance 3 years after peginterferon alfa-2a treatment and determined the incidence of hepatocellular carcinoma. METHODS: A prospective, international, multicenter, observational study in patients with chronic hepatitis B who have been prescribed peginterferon alfa-2a (40KD) in a real-world setting. The primary endpoint was HBsAg clearance after 3 years' follow-up. RESULTS: The modified intention-to-treat population comprised 844 hepatitis B e antigen (HBeAg)-positive patients (540 [64%] completed 3 years' follow-up), and 872 HBeAg-negative patients (614 [70%] completed 3 years' follow-up). At 3 years' follow-up, HBsAg clearance rates in HBeAg-positive and HBeAg-negative populations, respectively, were 2% (16/844) and 5% (41/872) in the modified intention-to-treat population and 5% [16/328] and 10% [41/394] in those with available data. In HBeAg-positive patients with data, Week 12 HBsAg levels <1500, 1500-20,000, and >20,000 IU/mL were associated with HBsAg clearance rates at 3 years' follow-up of 11%, 1%, and 5%, respectively (Week 24 predictability was similar). In HBeAg-negative patients with available data, a ≥10% decline vs a <10% decline in HBsAg at Week 12 was associated with HBsAg clearance rates of 16% vs 4%. Hepatocellular carcinoma incidence was lower than REACH-B (Risk Estimation for Hepatocellular Carcinoma in Chronic Hepatitis B) model predictions. CONCLUSIONS: Sustained off-treatment immune control is achieved with peginterferon alfa-2a in a real-world setting. HBsAg clearance 3 years after completion of peginterferon alfa-2a can be predicted on the basis of on-treatment HBsAg kinetics.

RESUMEN

INTRODUCTION AND OBJECTIVE: Hepatitis C virus (HCV) infection and treatment impact the patient's daily life and work productivity. Until recently, treatments were associated with side effects and insufficient virologic and hepatic results. This study evaluated fatigue, work productivity, and treatment modalities in patients with HCV infection. MATERIALS AND METHODS: This cross-sectional, non-interventional, multicenter study was conducted in real-life settings between March and December 2015 at 109 sites in France. RESULTS: Data from 1269 patients were evaluable. The mean patient age was 55.8±12.5 years; 53.3% (676) patients were male. A total of 80.1% (1015) of patients were Caucasian and 62.3% (791) had a genotype 1 infection, 34.2% (433) had at least one comorbidity and 15.6% (198) had ≥1 clinical sign/symptom. Illicit drug use was the main route of HCV transmission and accounted for 36.8% (466) of all infections. Fibrosis stage F0/F1 was reported in 41.4% (525) of patients. A majority of patients (60.4%, 764) had never been treated. In patients previously treated, 85.8% (430) received ribavirin and pegylated interferon and only 13.4% (67) direct-acting antivirals. The mean percent of global impairment due to health was highest (34.8±30.9%) in patients 18-45 years of age. The prevalence of active employed patients with a total fatigue score≥its median value (45/160) was 38.6%. The mean percent work time missed due to health was 9.6±23.6% for working patients of 18-45 years of age and 7.3±21.8% for working patients of 45-65 years of age. The mean overall prevalence of employed patients with impairment due to health issues was 21.8±26.8%. The prevalence of patients with a reduced work activity of ≥50% due to their health status was 32.1%. CONCLUSION: These data reinforce the request for improved disease management in France, allowing patients with HCV infection to increase work productivity, reduce fatigue, and, hopefully, cure their disease.

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

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

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

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: 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

BACKGROUND: A few direct antiviral agents have been studied in difficult-to-treat patients infected by hepatitis C virus (HCV) genotype 4 (GT4). The efficacy of daclatasvir (DCV), asunaprevir (ASV), pegylated interferon and ribavirin (Peg-IFN/RBV) association was investigated in these patients. PATIENTS AND METHODS: This open-label, single-arm, phase 2 study was conducted in HCV GT4 patients who were null or partial responders to Peg-IFN/RBV. Patients received 24 weeks of DCV (60 mg, once daily), ASV (100 mg, twice daily) and Peg-IFN/RBV. The primary endpoint was sustained virologic response at post-treatment week 12 [sustained virologic response (SVR)12]. RESULTS: Sixty patients were included; 45 (75%) were previous null responders and 27 (45%) had cirrhosis. The most frequent subtypes were GT4a (48%) and GT4d (27%) with 25% of the patients being infected with other subtypes such as 4c, 4r, 4f, 4k, 4j and 4q. The global SVR12 was 95% (90% confidence interval: 90.4-99.6) and 96.3% (90% confidence interval: 87.5-99.5) in cirrhotic patients. All patients achieving SVR12 also achieved SVR24. Previous Peg-IFN/RBV response, IL28b genotype, cirrhosis status or GT4 subtypes did not influence SVR12 rates. Serious adverse events occurred in 13% of the patients, four being cirrhotic and four noncirrhotic. Three (5%) patients stopped HCV therapy prematurely: one because of virologic breakthrough and two because of serious adverse events. Grade 3/4 laboratory abnormalities included leukopenia (33%), neutropenia (27%), thrombocytopenia (4%) and transaminases increase (2%). CONCLUSION: Association of DCV plus ASV and peg-IFN/RBV for 24 weeks demonstrated a high rate of SVR12 in HCV GT4-infected prior nonresponders, independently of the cirrhotic status or the GT4 subtype. The safety profile was acceptable, even in cirrhotic patients.
