INTRODUCTION/BACKGROUND:Treatment options are limited for people infected with hepatitis C virus (HCV) with decompensated liver disease. The C-SALT study assessed elbasvir (EBR) plus grazoprevir (GZR) in individuals with HCV genotype 1 infection and Child-Pugh class B (CP-B) cirrhosis. METHODS:In this 12-week, phase 2, nonrandomized, open-label study (NCT02115321; Protocol MK-5172-059), participants with CP-B cirrhosis received EBR 50 mg plus GZR 50 mg once daily, and a control group of noncirrhotic participants received EBR 50 mg plus GZR 100 mg once daily. The primary endpoint was sustained virologic response 12 weeks after the end of therapy. RESULTS:Sustained virologic response at 12 weeks after the end of therapy was achieved by 27/30 (90.0%) CP-B participants and 10/10 (100.0%) noncirrhotic participants. Two participants relapsed, and one died during follow-up after having undetectable HCV RNA at the end of treatment. Most CP-B participants had stable or improved model for end-stage liver disease and Child-Pugh scores at follow-up week 12 compared with baseline. There was no significant difference in drug exposure between groups, despite the differing GZR dose. Adverse events occurring in >10% of participants were fatigue (CP-B: 30.0%; noncirrhotic: 30.0%), arthralgia (16.7%; 20.0%), nausea (10.0%; 20.0%), and headache (10.0%; 50.0%). No serious treatment-related adverse events or hepatic events of clinical interest occurred. CONCLUSIONS:EBR 50 mg plus GZR 50 mg once daily for 12 weeks was highly effective and well tolerated in a traditionally hard-to-treat population. TRANSLATIONAL IMPACT/UNASSIGNED:Although EBR plus reduced-dose GZR is not available for people with CP-B cirrhosis, these results complement phase 2/3 trial data and real-world experience with EBR/GZR.Open Access This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

BACKGROUND:While hepatitis B and C have been the main drivers of hepatocellular carcinoma (HCC), non-alcoholic steatohepatitis (NASH) has recently become an important cause of HCC. The aim of this study was to assess the causes of HCC among liver transplant (LT) candidates in the U.S. METHODS:The Scientific Registry of Transplant Recipients (2002-2016) was used to estimate the trends in prevalence of HCC in LT candidates with the most common types of chronic liver disease: alcoholic liver disease (ALD), chronic hepatitis B (CHB), chronic hepatitis C, and NASH. RESULTS:158,347 adult LT candidates were included. Of these, 26,121 (16.5%) had HCC; this proportion increased from 6.4% (2002) to 23.0% (2016) (trend p<0.0001). Over the study period, CHC remained the most common etiology for HCC (65%). The proportions of HCC accounted for by CHC and ALD remained stable (both trend p>0.10), the proportion of CHB decreased 3.1-fold (p<0.0001), while the proportion of NASH in HCC increased 7.7-fold (from 2.1% to 16.2%, p<0.0001). Furthermore, since 2002, the prevalence of HCC in LT candidates with NASH increased 11.8-fold, while this rate increased 6.0-fold in CHB, 3.4-fold in ALD and 2.3-fold in CHC (all p<0.0001); the increasing trend in NASH was steeper than that for any other etiology (p<0.0001 in a trend regression model). The proportion of LT candidates with HCC who were ultimately transplanted or died while waiting did not differ between etiologies (p>0.05). CONCLUSIONS:Non-alcoholic steatohepatitis is the most rapidly growing cause of HCC among U.S. patients listed for liver transplantation.

European treatment guidelines for hepatitis C virus (HCV) infection recommend that people with genotype (GT) 1a infection and baseline viral load ≤800 000 IU/mL receive elbasvir/grazoprevir (EBR/GZR) for 12 weeks, and those with baseline viral load >800 000 IU/mL receive EBR/GZR plus ribavirin for 16 weeks. This analysis was conducted to clarify whether baseline viral load can serve as an accurate, sensitive or specific stratification factor for defining EBR/GZR regimens. In this post hoc, integrated analysis, participants with GT1a infection who received EBR 50 mg/GZR 100 mg for 12 weeks were stratified according to baseline viral load. Sustained virologic response at 12 weeks post-treatment was achieved by 95.2% (911/957) of participants and was higher among participants with baseline viral load ≤800 000 IU/mL vs >800 000 IU/mL (98.5% vs 93.9%). The 800 000 IU/mL threshold had a positive predictive value of 98.5%, a negative predictive value of 6.1%, a specificity of 91.3%, a sensitivity of 28.4% and an overall accuracy of 31.5%. A baseline viral load cutpoint of 800 000 IU/mL had high positive predictive value and specificity but poor negative predictive value, sensitivity and accuracy in predicting treatment outcomes in this population. Baseline NS5A resistance-associated substitutions (RASs) were detected in 25% (1/4) of virologic failures with baseline viral load ≤800 000 IU/mL and 59.5% (25/42) of those with baseline viral load >800 000 IU/mL. Overall, these data suggest that, compared with the use of a baseline viral load cutpoint, baseline testing for NS5A RASs enables more individuals to receive the 12-week EBR/GZR regimen without compromising the opportunity for SVR.

Background: Chronic hepatitis C (CHC) and non-alcoholic steatohepatitis (NASH) are both associated with impairment of healthrelated quality of life (HRQL). The most profound impairment is usually seen in patients with cirrhosis.
Aim(s): To compare HRQL scores in patients with cirrhosis due to CHC to NASH.
Method(s): Patients with CHC and NASH and compensated cirrhosis completed SF-36, CLDQ, and Work Productivity and Activity questionnaires while off-treatment.
Result(s): We included 1460 patients with NASH or CHC and cirrhosis: 57.4 +/- 8.2 years, 44% male, 40% history of psychiatric disorders, 50% employed (all p>0.05 between NASH and CHC). Cirrhotic patients with NASH had higher BMI (mean 33.8 vs. 28.2) and more type 2 diabetes (77% vs. 18%) (p<0.01). Patients with NASH had lower HRQL in Physical Functioning, Bodily Pain, General Health domains, and Physical Summary of SF-36 (by 3.6-4.4 points on a 0-100 scale, all p<0.01). Despite this, patients with CHC had lower Mental Health score of SF-36 (mean 69.5 vs. 73.0) and Emotional score of CLDQ (mean 4.9 vs. 5.3 on a 1-7 scale), and higher Activity Impairment score of WPAI (0.27 vs. 0.19) (all p<0.002). In multivariate regression analysis, after adjustment for demographic and clinical parameters, having NASH was independently associated with lower physical HRQL scores (beta - 3.6 to - 4.3 for SF-36 domains) and higher mental health-related scores (beta +3.8 for Mental Health of SF-36, +0.33 for Emotional of CLDQ) (all p<0.01).
Conclusion(s): Patients with NASH and cirrhosis have more impairment of their physical health-related scores than demographically similar patients with hepatitis C

Primary biliary cholangitis (PBC) is a chronic, cholestatic, autoimmune disease with a variable progressive course. PBC can cause debilitating symptoms including fatigue and pruritus and, if left untreated, is associated with a high risk of cirrhosis and related complications, liver failure, and death. Recent changes to the PBC landscape include a name change, updated guidelines for diagnosis and treatment as well as new treatment options that have recently become available. Practicing clinicians face many unanswered questions when managing PBC. To assist these healthcare providers in managing patients with PBC, the American College of Gastroenterology (ACG) Institute for Clinical Research & Education, in collaboration with the Chronic Liver Disease Foundation (CLDF), organized a panel of experts to evaluate and summarize the most current and relevant peer-reviewed literature regarding PBC. This, combined with the extensive experience and clinical expertise of this expert panel, led to the formation of this clinical guidance on the diagnosis and management of PBC.
