Hepatitis B Delta: assessment of the knowledge and practices of hepato-gastroenterologists practicing in non-academic settings in France.

BACKGROUND: Data on the management of Hepatitis B-Delta (HB-D) by hepatogastroenterologists (HGs) practicing in nonacademic hospitals or private practices are unknown in France. OBJECTIVE: We aimed to evaluate the knowledge and practices of HGs practicing in nonacademic settings regarding HB-D. METHODS: A Google form document was sent to those HGs from May to September 2021. RESULTS: A total of 130 HGs (mean age, 45 years) have participated in this survey. Among HBsAg-positive patients, Delta infection was sought in only 89% of cases. Liver fibrosis was assessed using FibroScan in 77% of the cases and by liver biopsy in 81% of the cases. A treatment was proposed for patients with >F2 liver fibrosis in 49% of the cases regardless of transaminase levels and for all the patients by 39% of HGs. Responding HGs proposed a treatment using pegylated interferon in 50% of cases, bulevirtide in 45% of cases and a combination of pegylated interferon and bulevirtide in 40.5% of cases. Among the criteria to evaluate the treatment efficacy, a decrease or a normalization of transaminases was retained by 89% of responding HGs, a reduction of liver fibrosis score for 70% of them, an undetectable delta RNA and HBsAg for 55% of them and a 2 log 10 decline in delta viremia for 62% of the cases. CONCLUSION: Hepatitis Delta screening was not systematically performed in HBsAg-positive patients despite the probable awareness and knowledge of the few responders who were able to prescribe treatments of hepatitis delta.

Extensive splanchnic vein thrombosis after SARS-CoV-2 vaccination: A Vascular Liver Disease Group (VALDIG) initiative.

BACKGROUND AND AIMS: Since the introduction of SARS-CoV-2 vaccines, several cases of vaccine-induced immune thrombocytopenia and thrombosis (VITT) have been described, especially cerebral vein thrombosis. We aimed to retrospectively collect all new cases of acute onset first or recurrent splanchnic vein thrombosis (SVT) following a recent SARS-CoV-2 vaccination within the Vascular Liver Disease Group network. APPROACH AND RESULTS: New cases of SVT were identified from April 2021 to April 2022; follow-up was completed on December 31, 2022. Criteria to define VITT were derived from previous studies. Data from a pre-COVID cohort of patients with SVT (N=436) were used for comparison of clinical presentation, etiology, and outcome. Twenty-nine patients were identified with SVT occurring with a median of 11 days (range 2-76) after the first (48%), second (41%), or third (10%) vaccination (ChAdOx1 nCov-19 (n=12) or BNT162b2 (n=14), other (n=3) Only 2 patients(7%) fulfilled criteria for definite VITT. Twenty (69%) had SVT at multiple sites, including 4 (14%) with concomitant extra-abdominal thrombosis. Only 28% had an underlying prothrombotic condition, compared to 52% in the pre-COVID SVT cohort ( p =0.01). Five patients (17%) underwent bowel resection for mesenteric ischemia, compared with 3% in pre-COVID SVT ( p <0.001). Two patients died shortly after diagnosis (7%). CONCLUSIONS: Although definite VITT was rare, in 72% of cases, no other cause for SVT could be identified following SARS-CoV-2 vaccination. These cases were different from patients with nonvaccine-related SVT, with lower incidence of prothrombotic conditions, higher rates of bowel ischemia, and poorer outcome. Although SVT after SARS-CoV-2 vaccination is rare in absolute terms, these data remain relevant considering ongoing revaccination programs.

International survey among hepatologists and pulmonologists on the hepatic hydrothorax: plea for recommendations.

BACKGROUND: The Hepatic hydrothorax is a pleural effusion related to portal hypertension; its diagnosis and therapeutic management may be difficult. The aims of this article are which follows: To gather the practices of hepatogastroenterologists or pulmonologists practitioners regarding the diagnosis and management of the hepatic hydrothorax. METHODS: Practitioners from 13 French- speaking countries were invited to answer an online questionnaire on the hepatic hydrothorax diagnosis and its management. RESULTS: Five hundred twenty-eight practitioners (80% from France) responded to this survey. 75% were hepatogastroenterologists, 20% pulmonologists and the remaining 5% belonged to other specialities. The Hepatic hydrothorax can be located on the left lung for 64% of the responders (66% hepatogastroenterologists vs 57% pulmonologists; p = 0.25); The Hepatic hydrothorax can exist in the absence of clinical ascites for 91% of the responders (93% hepatogastroenterologists vs 88% pulmonologists; p = 0.27). An Ultrasound pleural scanning was systematically performed before a puncture for 43% of the responders (36% hepatogastroenterologists vs 70% pulmonologists; p < 0.001). A chest X-ray was performed before a puncture for 73% of the respondeurs (79% hepatogastroenterologists vs 54% pulmonologists; p < 0.001). In case of a spontaneous bacterial empyema, an albumin infusion was used by 73% hepatogastroenterologists and 20% pulmonologists (p < 0.001). A drain was used by 37% of the responders (37% hepatogastroenterologists vs 31% pulmonologists; p = 0.26).An Indwelling pleural catheter was used by 50% pulmonologists and 22% hepatogastroenterologists (p < 0.01). TIPS was recommended by 78% of the responders (85% hepatogastroenterologists vs 52% pulmonologists; p < 0.001) and a liver transplantation, by 76% of the responders (86% hepatogastroenterologists vs 44% pulmonologists; p < 0.001). CONCLUSIONS: The results of this large study provide important data on practices of French speaking hepatogastroenterologists and pulmonologists; it appears that recommendations are warranted.

An observational, prospective, multicenter study on the utilization and effectiveness of elbasvir-grazoprevir treatment association for chronic hepatitis C in France (ZEPHYR study).

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.

Clinical outcomes after treatment with direct antiviral agents: beyond the virological response in patients with previous HCV-related decompensated cirrhosis.

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.

Non-invasive diagnosis and follow-up of chronic infection with hepatitis B virus.

Diagnosis of chronic hepatitis B virus (HBV) infection, initial staging of infection and monitoring of treated and untreated patients are mainly based on clinical, biological and imaging criteria allowing a complete non-invasive management for the majority of patients. Along to the conventional virological tools, rapid diagnostic tests and blotting paper tests for HBV DNA are validated alternatives. After diagnosis, the initial work-up should include HIV, HCV and HDV serologies, HBeAg status, and HBsAg and HBV DNA quantification. Assessment of severity (inflammation and fibrosis) is based on ALT serum levels and non-invasive evaluation of liver fibrosis by elastography or blood tests, which must be interpreted cautiously using specific cut-offs and taking into account ALT levels. Taken together, these parameters allow disease classification and treatment decision. Decision of hepatocellular carcinoma screening by ultra-sound every six months may be difficult in non-cirrhotic patients and the use of risk-scores such as PAGE-B is encouraged. Chronic HBV infection often has a dynamic and often unpredictable profile and regular monitoring is mandatory. In untreated patients, regular (3-12 months) follow-up should include ALT and HBV DNA serum levels. Periodical HBsAg quantification and non-invasive evaluation of liver fibrosis may refine disease outcome and prognosis. In treated patients, checking efficacy is mainly based on HBV DNA negativity. In patients with advanced fibrosis, evolution of liver stiffness can be useful for portal hypertension evaluation, but its improvement should not be considered to stop hepatocellular carcinoma screening. Finally, new parameters (HBV RNA, HBcrAg) are promising but their use is still restricted for research.

A simple clinical score to promote and enhance ferroportin disease screening.

BACKGROUND & AIMS: Ferroportin disease is a rare genetic iron overload disorder which may be underdiagnosed, with recent data suggesting it occurs at a higher prevalence than suspected. Costs and the lack of defined criteria to prompt genetic testing preclude large-scale molecular screening. Hence, we aimed to develop a readily available scoring system to promote and enhance ferroportin disease screening. METHODS: Our derivation cohort included probands tested for ferroportin disease from 2008 to 2016 in our rare disease network. Data were prospectively recorded. Univariate and multivariate logistic regression were used to determine significant criteria, and odds ratios were used to build a weighted score. A cut-off value was defined using a ROC curve with a predefined aim of 90% sensitivity. An independent cohort was used for cross validation. RESULTS: Our derivation cohort included 1,306 patients. Mean age was 55±14 years, ferritin 1,351±1,357 µg/L, and liver iron concentration (LIC) 166±77 µmol/g. Pathogenic variants (n = 32) were identified in 71 patients. In multivariate analysis: female sex, younger age, higher ferritin, higher LIC and the absence of hypertension or diabetes were significantly associated with the diagnosis of ferroportin disease (AUROC in whole derivation cohort 0.83 [0.78-0.88]). The weighted score was based on sex, age, the presence of hypertension or diabetes, ferritin level and LIC. An AUROC of 0.83 (0.77-0.88) was obtained in the derivation cohort without missing values. Using 9.5 as a cut-off, sensitivity was 93.6 (91.7-98.3) %, specificity 49.5 (45.5-53.6) %, positive likelihood ratio 1.8 (1.6-2.0) and negative likelihood ratio 0.17 (0.04-0.37). CONCLUSION: We describe a readily available score with simple criteria and good diagnostic performance that could be used to screen patients for ferroportin disease in routine clinical practice. LAY SUMMARY: Increased iron burden associated with metabolic syndrome is a very common condition. Ferroportin disease is a dominant genetic iron overload disorder whose prevalence is higher than initially thought. They can be difficult to distinguish from each other, but the limited availability of genetic testing and the lack of definitive guidelines prevent adequate screening. We herein describe a simple and definitive clinical score to help clinicians decide whether to perform genetic testing.

Predictive factors for hepatocellular carcinoma in chronic hepatitis B using structural equation modeling: a prospective cohort study.

BACKGROUND & AIMS: The factors predicting hepatocellular carcinoma (HCC) occurrence in chronic hepatitis B need to be precisely known to improve its detection. We identified pathways and individual predictive factors associated with HCC in the ANRS CO22 HEPATHER cohort. METHODS: The study analyzed HBV-infected patients recruited at 32 French expert hepatology centers from August 6, 2012, to December 31, 2015. We excluded patients with chronic HCV, HDV and a history of HCC, decompensated cirrhosis or liver transplantation. Structural equation models were developed to characterize the causal pathways leading to HCC occurrence. The association between clinical characteristics (age, gender, body-mass index, liver fibrosis, alcohol consumption, smoking status, diabetes, hypertension, dyslipidemia, alpha-fetoprotein, HBV DNA levels, antiviral therapy) and incident HCC was quantified. RESULTS: Among the 4489 patients included, 33 patients reported incident HCC. The median follow-up was 45.5 months. Age (ß = 0.18 by decade, 95% CI 0.14-0.23), male gender (ß = 0.23, 95% CI 0.18-0.29), metabolic syndrome (ß = 0.28, 95% CI 0.22-0.33), alcohol consumption (ß = 0.09, 95% CI 0.05-0.14) and HBV DNA (ß = 0.25, 95% CI 0.170.34) had a significant and direct effect on the occurrence of advanced liver fibrosis. Liver fibrosis (ß = 0.71, 95% CI 0.55-0.87) predicted, in turn, the occurrence of HCC. CONCLUSIONS: Liver fibrosis mediates the effects of age, gender, alcohol, metabolic syndrome and HBV DNA on the occurrence of HCC. Elderly men with chronic hepatitis B, risky alcohol use, advanced liver fibrosis, metabolic syndrome and high HBV DNA levels should be monitored closely to detect the development of HCC.

Evaluation of Longitudinal Exposure to Tacrolimus as a Risk Factor of Chronic Kidney Disease Occurrence Within the First-year Post-Liver Transplantation.

BACKGROUND: Renal failure is predictive of mortality in the early postliver-transplantation period and calcineurin inhibitors toxicity is a main challenge. Our aim is to assess the impact of longitudinal tacrolimus exposure (TLE) and other variables on chronic kidney disease (CKD)-free 1-year-survival. METHODS: Retrospective data of consecutive patients transplanted between 2011 and 2016 and treated with tacrolimus were collected. TLE and all relevant pre- and post-liver transplantation (LT) predictive factors of CKD were tested and included in a time-to-event model. CKD was defined by repeated estimated glomerular filtration rate (eGFR) values below 60 mL/min/1.73m2 at least for the last 3 months before M12 post-LT. RESULTS: Data from 180 patients were analyzed. CKD-free survival was 74.5% and was not associated with TLE. Pre-LT acute kidney injury (AKI) and eGFR at 1-month post-LT (eGFRM1) <60 mL/min/1.73m2 were significant predictors of CKD. By distinguishing 2 situations within AKI (ie, with or without hepatorenal syndrome [HRS]), only HRS-AKI remained associated to CKD. HRS-AKI and eGFRM1 <60 mL/min/1.73m2 increased the risk of CKD (hazard ratio, 2.5; 95% confidence interval, 1.2-4.9; hazard ratio, 4.8; 95% confidence interval, 2.6-8.8, respectively). CONCLUSIONS: In our study, TLE, unlike HRS-AKI and eGFRM1, was not predictive of CKD-free survival at 1-year post-LT. Our results once again question the reversibility of HRS-AKI.

Management of primary biliary cholangitis: results from a large real-life observational study in France and Belgium.

BACKGROUND AND AIMS: To assess the characteristics, care, treatment response, and outcomes of primary biliary cholangitis (PBC) patients recently followed-up by hepato-gastroenterologists in various French and Belgian healthcare settings. METHODS: This retrospective cohort study included patients with PBC who recently visited 79 hepato-gastroenterologists in France and Belgium. Data were collected at the time of diagnosis and at last visit and were compared according to biochemical response (BR) to ursodeoxycholic acid (UDCA) (BR), using Paris I-II criteria, and clinical outcomes. RESULTS: A total of 436 patients (mean age at diagnosis 57 years, 88% females, median follow-up 5.2 years) were included. Liver biopsy, transient elastography, or none of these two procedures were performed at baseline in 216 (50%), 194 (45%), and 107 (25%) patients, respectively. Late-stage disease (histological stage III or IV, or transient elastography ≥9.6 kPa, or bilirubin >17 µM and albumin <35 g/L, or platelets <150.000/µl, or unequivocal signs of portal hypertension or cirrhosis) was reported in 37% of patients. UDCA was taken by 95% of patients (27% had suboptimal dosage). Inadequate BR was observed in 37% of patients. Clinicians overestimated disease control. Liver-related complications occurred in 9% of patients. Bilirubin and albumin independently predicted inadequate BR; advanced disease stage and inadequate BR independently predicted complications. CONCLUSIONS: Recently followed-up French and Belgian patients with PBC had homogeneous management. Late stage at diagnosis and inadequate BR were reported in around 40% of patients. Disease control was frequently overestimated by clinicians. Disease stage and BR were the main prognostic factors.

Revisiting HBV resistance to entecavir with a phenotypic approach.

Treatment adaptation after hepatitis B virus (HBV) treatment failure relies on genotypic resistance testing. However, the results of such tests are not always consistent with treatment response. These discrepancies may be due to differences in resistance levels between isolates with the same genotypic resistance testing profiles. We explored this hypothesis by investigating six cases of entecavir treatment failure with an integrative strategy combining genotypic and phenotypic resistance testing, medical record review and therapeutic drug monitoring. Among isolates with genotypic reduced susceptibility to entecavir, one displayed a higher level of resistance to entecavir (mean fold change in entecavir IC50 of 1 508 ± 531 vs. 318 ± 53, p = 0.008). This isolate harbored a substitution (rt250L) at a position reported to be associated with resistance (rt250V). Reversion to wild-type amino acid at this position partially restored susceptibility to entecavir, confirming that the rt250L mutation was responsible for the high level of resistance to entecavir. This is the first description of entecavir treatment failure associated with selection of the rt250L mutation without other entecavir resistance mutations. One isolate with genotypic resistance to entecavir, harboring the rt173L mutation, displayed a lower level of resistance than the other, harboring the rt202G mutation (mean fold change of 323 ± 124 vs. 6 036 ± 2 100, p = 0.20). These results suggest that isolates harboring the rt250L mutations should be considered resistant to entecavir, whereas isolates harboring the rt173L mutations should be considered to display reduced susceptibility to entecavir. An integrative approach to antiviral drug resistance in HBV would provide a more accurate assessment of entecavir treatment failures and help to improve the accuracy of genotypic testing algorithms.

Efficacy and safety of treatment of chronic hepatitis C with sofosbuvir and ribavirin with or without peginterferon: a French prospective real-life cohort study of unselected 211 patients.

INTRODUCTION: Sofosbuvir is the first directly-acting antiviral for the treatment of hepatitis C virus. First, the regimens were combinations with sofosbuvir+ribavirin (SR) or with sofosbuvir+ribavirin and pegylated-interferon α-2a (SPR) with cure rates around 90%. The aim of this study was to report the results of these combinations in 'real-life' in France. MATERIALS AND METHODS: Main features of patients treated with SR or SPR in 24 hospitals were collected. Undetectable hepatitis C virus week 12 viral load after treatment defined sustained virological response (SVR12). Statistics were performed using StatView software for descriptive analysis and χ for the sub-groups comparisons. RESULTS: Two hundred and eleven patients were analyzed. The average age was 56.1. One hundred and seventy-one (89%) patients had a fibrosis score of at least 3. Seventy-nine patients were infected by a genotype 1 (G1). One hundred and thirteen patients were treated with SR and 95 with SPR. In naive patients: with SPR for 12 weeks, SVR12 was 93% in G1, 100% in G3 and 83% in G4. With SR for 12 weeks, SVR12 was 100% in G2 patients (6/6). The safety of these regimens was satisfactory with only two patients who had to stop P due to severe side effects. Multivariate analysis shows a higher SVR in SPR versus SR (odds ratio = 1.28; P = 0.05) and in G2 or G3 versus others (odds ratio = 1.56; P = 0.04). Moreover, Child-Pugh score B or C (P = 0.02), platelets count under 100G/l (P = 0.05) or a past event of ascites (P = 0.04) was independently associated with less SVR. CONCLUSION: This multicenter large study confirms the good results of SR for 12 weeks in G2 naive patients. Finally, a decompensated cirrhosis, a past event of ascites and a baseline low platelet count were strongly associated with poor response.

Effects of Age on Treatment of Chronic Hepatitis C with Direct Acting Antivirals.

INTRODUCTION AND AIM: Data on the efficacy and tolerance of interferon-free treatment in chronic hepatitis C (CHC) in elderly patients are limited in phase II-III trials. MATERIAL AND METHODS: A prospective cohort of adult patients with CHC treated in French general hospitals. RESULTS: Data from 1,123 patients, distributed into four age groups, were analyzed. Of these, 278 were > 64 years old (fourth quartile) and 133 were > 73 years old (tenth decile). Elderly patients weighed less, were more frequently treatment-experienced women infected with genotype 1b or 2, while they less frequently had genotype 3 or HIV coinfection, but had more frequent comorbidities and drug consumption. Half of the patients had cirrhosis, whatever their ages. The main treatment regimens were sofosbuvir/ledipasvir (37.8%), sofosbuvir/daclatasvir (31.8%), sofosbuvir/simeprevir (16.9%), sofosbuvir/ribavirin (7.8%); ribavirin was given to 24% of patients. The overall sustained virological response (SVR) rate was 91.0 % (95% CI: 89.292.5%) with no difference according to age. Logistic regression of the independent predictors of SVR were albumin, hepatocellular carcinoma and treatment regimen, but not age. The rate of severe adverse events (66 in 59/1062 [5.6%] patients) tended to be greater in patients older than 64 years of age (21/261,8.1%), but the only independent predictors of SAE by logistic regression were cirrhosis and baseline hemoglobin. Patient-reported overall tolerance was excellent in all age groups, and patient-reported fatigue decreased during and after treatment, independent of age. CONCLUSIONS: The high efficacy and tolerance of interferon-free regimens is confirmed in elderly patients in real-life conditions.

Safety and efficacy of the combination simeprevir-sofosbuvir in HCV genotype 1- and 4-mono-infected patients from the French ANRS CO22 hepather cohort.

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 .

Hepatitis C treatment with all-oral direct-acting antivirals: Effectiveness and tolerance in a multicenter, prospective, observational study from French general hospitals (APROVVIE, ANGH).

BACKGROUND AND AIMS: According to clinical trials, the treatment of patients with chronic hepatitis C (CHC) with second-generation direct acting antiviral agents (DAAs) is highly efficient and well tolerated. The goal of this study was to investigate the effectiveness and safety of various combinations of these drugs during their first 2 years of use in the real-world practice of French general hospitals. METHODS: Data from patients treated with all-oral DAAs in 24 French non-academic hospital centers from March 1, 2014 to January 1, 2016, were prospectively recorded. The sustained virological response 12-24 weeks after treatment (SVR 12-24) was estimated and severe adverse events (SAE) were evaluated and their predictive factors were determined using logistic regression. RESULTS: Data from 1123 patients were analyzed. The population was 69% genotype (G) 1, 13% G3, 11.5% G4, 5% G2, 49% with cirrhosis and 55% treatment-experienced. The treatment regimens were sofosbuvir/ledipasvir (38%), sofosbuvir/daclatasvir (32%), sofosbuvir/simeprevir (17%), ombitasvir+paritaprevir+ritonavir (5%) (with dasabuvir 3.5%), and sofosbuvir/ribavirin (8%). Ribavirin was given to 24% of patients. The SVR 12-24 was 91.0% (95% CI: 89.2-92.5%). Sofosbuvir-ribavirin was less effective than other regimens. The independent predictors of SVR 12-24 by logistic regression were body weight, albumin, previous hepatocellular carcinoma and treatment regimen (sofosbuvir/ribavirin vs. others). Sixty-four severe adverse events (SAE) were observed in 59 [5.6%] patients, and were independently predicted by cirrhosis and baseline hemoglobin. Serum creatinine increased during treatment (mean 8.5%, [P<10-5]), satisfying criteria for acute kidney injury in 62 patients (7.3%). Patient-reported overall tolerance was excellent, and patient-reported fatigue decreased during and after treatment. CONCLUSIONS: Second generation DAAs combinations are as effective and well tolerated in a « real-world ¼ population as in clinical trials. Further studies are needed on renal tolerance.

Clinical outcomes in patients with chronic hepatitis C after direct-acting antiviral treatment: a prospective cohort study.

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.

Increased incidence of Campylobacter enteritis and their quinolone resistance between 2010 and 2015: Results of a French national observatory conducted in 21 general hospitals (CHG).

INTRODUCTION: In Europe, the number of cases of Campylobacter enteritis and their quinolone resistance is increasing. The aims of this work were to evaluate: (1) the hospital epidemiology of bacterial enteritis between 2010 and 2015. (2) The proportion of Campylobacter and Salmonella enteritis. (3) Resistance to quinolones in adult and paediatric populations. (4) To investigate possible regional epidemiological and bacteriological disparities. PATIENTS AND METHODS: This is a multicentric study carried out in 21 general hospitals (CHG) representing 14 French regions with a prospective collection of the results of coprocultures from 2010 to 2015 in adult and paediatric populations (children < 15 years old not exposed to quinolones). The epidemiological and bacteriological data were collected from software laboratory for positive stool cultures for Campylobacter and Salmonella. The results were compared year by year and by a period of 2 years. RESULTS: In adults, Campylobacter enteritis was each year significantly more frequent than Salmonella (P < 0.001), with a significant increase from 2010 to 2015 (P < 0.05). In children, there was also a significant and stable predominance of Campylobacter enteritis over the study period (P = 0.002). The quinolone resistance of Campylobacter was greater than 50% on the whole territory, with no North-South difference over the three periods studied. It increased significantly from 2012 to 2015 in adults (48% to 55%, P < 0.05) and in children (54% to 61%, P = 0.04). CONCLUSION: Our results confirm the increase in the prevalence of Campylobacter enteritis compared to Salmonella between 2010 and 2015. The quinolone resistance of Campylobacter is greater than 50% on the whole territory, stable between 2010 and 2015 in adults and significantly increased in children.

Severe liver failure rather than cirrhosis is associated with mortality in patients with infectious endocarditis: a retrospective case-control study.

BACKGROUND: Data on infectious endocarditis (IE) in patients with liver cirrhosis (LC) are sparse. We aimed to describe the characteristics and predictors of mortality from IE in patients with LC. PATIENTS AND METHODS: Overall, 101 patients with LC and 101 controls with IE matched for sex, age, date of IE, and diabetes were retrospectively selected in 23 liver units between 2000 and 2013. RESULTS: Mean age was 60.8±10.5 and 60.6±11.5 years in LC and controls, respectively. Causes of cirrhosis (Child-Pugh A/B/C: 10.4%/41.7%/47.9%, MELD score: 17±7.8) were excess alcohol intake (79.6%), viral hepatitis (17.3%), and metabolic syndrome (14.3%). Previous history of cardiopathy was found in 24.8% of LC (prosthetic valve 8.9%) and 37.6% of controls (P=0.07). The most frequent bacteria involved were gram-positive cocci. LC had significantly fewer aminoglycosides (P=0.0007), rifamycin (P=0.03), and valve surgery (P=0.02) than controls. The proportion of patients who died following cardiac surgery was similar between the two groups (9.7% for LC vs. 8.7% for controls, P=1). In-hospital mortality for Child-Pugh C patients was significantly higher than controls (61.4 vs. 23%, P<0.001), but not for Child-Pugh A (33.3%) or B patients (25.0%). A Child-Pugh score of above C10 was the best predictor of in-hospital mortality. In LC, Child-Pugh score (odds ratio=1.5; 95% confidence interval: 1.2-2.0; P=0.002) and history of decompensation (odds ratio=3.1; 95% confidence interval: 1.1-9.0; P=0.003) were independent predictive factors for in-hospital mortality. CONCLUSION: Severe liver failure but not cirrhosis is the strongest predictive factor of mortality related to IE in LC. Use of aminosides and rifamycin should be reassessed in LC, and cardiac surgery should be considered for selected patients.
