    BACKGROUND: The Enhanced Liver Fibrosis (ELF) score combining serum hyaluronan, N-terminal peptide of type III procollagen and tissue inhibitor of metalloproteinase-1, was reported as relevant in predicting liver fibrosis in chronic liver disease and proposed as an alternative to liver biopsy. METHODS: We evaluated the ELF score in a cohort of chronic hepatitis C (CHC) patients included in a multicenter prospective study (ANRS HC EP 23 Fibrostar) using commercial reagents, different from those developed by the manufacturer of the Siemens ELF test. RESULTS: In 512 CHC, the ELF score, using ROC curves, showed good predictive performances for severe fibrosis [AUROC=0.82; 95% confidence interval (CI) 0.78-0.86]and for cirrhosis (AUROC=0.85; 95% CI 0.81-0.90), but slightly lower for significant fibrosis (AUROC=0.78; 95% CI 0.74-0.82). The Obuchowski measure (0.81) showed that the ELF score globally performed as a marker of liver fibrosis. The ELF score predicted significant fibrosis (cut-off=9.0) with a sensitivity of 0.86, a specificity of 0.62, a positive predictive value (PPV) of 0.80 and a negative predictive value (NPV) of 0.70. For extensive fibrosis (cut-off=9.33), sensitivity was 0.90, specificity was 0.63, PPV was 0.73 and NPV was 0.85. For cirrhosis (cut-off=9.35), sensitivity was 0.83, specificity was 0.75, PPV was 0.44 and NPV was 0.95. CONCLUSIONS: This study confirms the ELF score performance as an index to predict liver fibrosis or cirrhosis in CHC. The ELF test, using validated reagents, could be added to the health authorities approved non-invasive tests in assessing fibrosis as surrogate to liver biopsy

    Genotype 1 hepatitis C virus envelope features that determine antiviral response assessed through optimal covariance networks

    The poor response to the combined antiviral therapy of pegylated alfa-interferon and ribavarin for hepatitis C virus (HCV) infection may be linked to mutations in the viral envelope gene E1E2 (env), which can result in escape from the immune response and higher efficacy of viral entry. Mutations that result in failure of therapy most likely require compensatory mutations to achieve sufficient change in envelope structure and function. Compensatory mutations were investigated by determining positions in the E1E2 gene where amino acids (aa) covaried across groups of individuals. We assessed networks of covarying positions in E1E2 sequences that differentiated sustained virological response (SVR) from non-response (NR) in 43 genotype 1a (17 SVR), and 49 genotype 1b (25 SVR) chronically HCV-infected individuals. Binary integer programming over covariance networks was used to extract aa combinations that differed between response groups. Genotype 1a E1E2 sequences exhibited higher degrees of covariance and clustered into 3 main groups while 1b sequences exhibited no clustering. Between 5 and 9 aa pairs were required to separate SVR from NR in each genotype. aa in hypervariable region 1 were 6 times more likely than chance to occur in the optimal networks. The pair 531-626 (EI) appeared frequently in the optimal networks and was present in 6 of 9 NR in one of the 1a clusters. The most frequent pairs representing SVR were 431-481 (EE), 500-522 (QA) in 1a, and 407-434 (AQ) in 1b. Optimal networks based on covarying aa pairs in HCV envelope can indicate features that are associated with failure or success to antiviral therapy

    Cirrhotic patients may present loculated ascites. We report a case of a 49-years old patient with cirrhosis and loculated infected ascites. Conventional and ultrasound (US)-guided paracentesis were ineffective. Moreover, US-guided drainages with 10 F drains could drain only small quantities of ascites localized in the largest loculated areas. Despite an adapted and long antibiotic therapy, the infection persisted. Intraabdominal fibrinolysis allowed the destruction of the fibrin septa, a better drainage and the sterilization of the ascites fluid. This is the first case report of effective intraabdominal fibrinolysis with urokinase in difficult to treat loculated infected ascites

    Safety and Antiviral Activity of EGFR Inhibition by Erlotinib in Chronic Hepatitis C Patients: A Phase Ib Randomized Controlled Trial

    Introduction: Significant hepatocellular carcinoma (HCC) risk persists after chronic hepatitis C (CHC) cure. Preclinical studies have shown that erlotinib, an oral epidermal growth factor receptor (EGFR) inhibitor, has an antiviral activity and HCC chemopreventive effect. Erlotinib is metabolized in the liver, and its safety in patients with CHC is unknown. This study aimed to assess the safety and antiviral activity of erlotinib in patients with CHC.Methods: In this investigator-initiated dose-escalation phase Ib prospective randomized double-blind placebo-controlled study, noncirrhotic hepatitis C virus (HCV) patients received placebo or erlotinib (50 or 100 mg/d) for 14 days with a placebo-erlotinib ratio of 1:3. Primary end points were safety and viral load reduction at the end of treatment (EOT). The secondary end point was viral load reduction 14 days after EOT.Results: This study analyzed data of 3 patients receiving placebo, 3 patients receiving erlotinib 50 mg/d, and 3 patients receiving erlotinib 100 mg/d. One grade 3 adverse event was reported in the placebo group (liver enzymes elevation), leading to treatment discontinuation and patient replacement, and 1 in the erlotinib 100 mg/d group (pericarditis), which was not considered to be treatment-related. Grade 2 skin rash was observed in 1 erlotinib 100 mg/d patient. No significant HCV-RNA level reduction was noted during treatment, but 2 of the 3 patients in the erlotinib 100 mg/d group showed a decrease of >0.5 log HCV-RNA 14 days after EOT.Discussion: Erlotinib demonstrated to be safe in noncirrhotic CHC patients. An antiviral activity at 100 mg/d confirms a functional role of EGFR as an HCV host factor in patients. These results provide perspectives to further study erlotinib as an HCC chemopreventive agent in patients with CHC

    BACKGROUND & AIMS: Entecavir (ETV) and tenofovir disoproxil fumarate (TDF) are potent antiviral agents that might have additive or synergistic antiviral activity in treatment of patients with chronic hepatitis B (CHB). We compared the efficacy and safety of ETV monotherapy with those of a combination of ETV and TDF. METHODS: We performed a randomized, open-label, multicenter, superiority study of 379 nucleos(t)ide-naive patients with hepatitis B e antigen (HBeAg)-positive (n = 264) or HBeAg-negative (n = 115) CHB. Subjects were given ETV 0.5 mg (n = 182) or a combination of ETV 0.5 mg and TDF 300 mg (n = 197) for 100 weeks. RESULTS: At week 96, comparable proportions of patients in each study arm achieved the primary end point of a level of hepatitis B virus (HBV) DNA /= 10(8) IU/mL (79% vs 62%) and not in those with baseline levels of HBV DNA /= 10(8) IU/mL

    BACKGROUND AND AIMS: Hepatitis C is poorly documented in migrants. The published studies mainly concern the screening in this population and are limited to some countries in Europe and North America. This study aimed to evaluate the characteristics and care of chronic hepatitis C in this population compared to the nonmigrant population, in the era of direct-acting antivirals (DAAs). METHOD: We performed a retrospective analysis based on data presented at the multidisciplinary team meetings of our tertiary care center between 2015 and 2019. RESULTS: We included 277 migrant- and 1390 nonmigrant patients mono-infected with hepatitis C virus (HCV) and treated with DAAs. The majority of the migrants were from Eastern European countries. In multivariable analysis, BMI classes associated with more obesity (OR = 1.84; 95% CI, 1.37-2.49; P < 0.001) and therapeutic patient education (OR = 3.91; 95% CI, 2.38-6.49; P < 0.001) were positively associated with migrant status, whereas age (OR = 0.92; 95% CI, 0.90-0.94; P < 0.001), female gender (OR = 0.46; 95% CI, 0.28-0.74; P = 0.002), modes of contamination with less drug use, transfusion history or nosocomial risk, as well more unknown mode (OR = 0.70; 95% CI, 0.50-0.96; P = 0.031), alcohol consumption (OR = 0.48; 95% CI, 0.29-0.73; P = 0.001), types of structures with less care in a general hospital or health network of general practitioners and more care in a university hospital or primary addictology center (OR = 0.78; 95% CI, 0.60-0.99; P = 0.046) and opioid substitution therapy (OR = 0.25; 95% CI, 0.08-0.68; P = 0.008) were negatively associated with migrant status. The substained virologic response 12 was close to 97% in both groups. CONCLUSION: Despite multiple differences in characteristics and therapeutic care between the two populations, the chances of healing hepatitis C were the same among migrant- compared with nonmigrant patients
