Non-invasive tests accurately stratify patients with NAFLD based on their risk of liver-related events.

Background & Aims: Previous studies on the prognostic significance of non-invasive liver fibrosis tests in non-alcoholic fatty liver disease (NAFLD) lack direct comparison to liver biopsy. We aimed to evaluate the prognostic accuracy of fibrosis-4 (FIB4) and vibration-controlled transient elastography (VCTE), compared to liver biopsy, for the prediction of liver-related events (LREs) in NAFLD.

Methods: A total of 1,057 patients with NAFLD and baseline FIB4 and VCTE were included in a multicenter cohort.

Non-invasive evaluation of response to obeticholic acid in patients with NASH: Results from the REGENERATE study.

Background & Aims: Non-alcoholic steatohepatitis (NASH) is a chronic, progressive fibrotic liver disease that can lead to cirrhosis. While liver biopsy is considered the reference standard for the histologic diagnosis of NASH and staging of fibrosis, its use in clinical practice is limited. Non-invasive tests (NITs) are increasingly being used to identify and stage liver fibrosis in patients with NASH, and several can assess liver-related outcomes.

Obeticholic Acid Impact on Quality of Life in Patients With Nonalcoholic Steatohepatitis: REGENERATE 18-Month Interim Analysis.

Background & Aims: Nonalcoholic steatohepatitis (NASH) affects patients' health-related quality of life (HRQoL). Patient-reported outcomes (PROs) evaluating HRQoL were assessed in the RandomizEd Global Phase 3 Study to Evaluate the Impact on NASH with FibRosis of Obeticholic Acid TreatmEnt (REGENERATE) study, which showed that obeticholic acid (OCA) significantly improved fibrosis in patients with NASH.

Methods: Noncirrhotic NASH patients in a phase 3, double-blind, randomized, placebo-controlled, multicenter, international study of OCA were enrolled.

Simplified follow-up of patients with mild chronic hepatitis C in areas with limited access to antiviral therapy.

Background And Aims: In some areas of the world, antiviral therapy for chronic hepatitis C (CHC) is not available for all patients. The optimal interval for liver stiffness measures (LSM) and noninvasive scores to assess fibrosis progression has not been studied. We evaluated the usefulness of consecutive LSM, APRI, FIB-4 and Forns scores to predict disease progression.

Effectiveness and safety of elbasvir/grazoprevir therapy in patients with chronic HCV infection: Results from the Spanish HEPA-C real-world cohort.

In randomized controlled trials of patients with chronic HCV infection, elbasvir/grazoprevir (EBR/GZR) demonstrated high cure rates and a good safety profile. This study assessed the effectiveness and safety of EBR/GZR, with and without ribavirin, in a real-world HCV patient cohort. HEPA-C is a collaborative, monitored national registry of HCV patients directed by the Spanish Association for the Study of the Liver and the Networked Biomedical Research Centre for Hepatic and Digestive Diseases.

Long-Term Outcomes of Patients With HCV-Associated Cryoglobulinemic Vasculitis After Virologic Cure.

Patients with hepatitis C virus-associated cryoglobulinemic vasculitis (HCV-CV) have high rates of clinical remission after treatment with direct-acting antivirals (DAAs), but circulating cryoglobulins persist, and vascular disorders reappear in some patients shortly after DAA treatment ends. We performed a prospective study to assess the long-term clinical and immune system effects of HCV eradication with DAAs in 46 patients with HCV-CV and 42 asymptomatic patients with circulating cryoglobulins. A median of 24 months after DAA treatment (range, 17-41 months), 66% of patients with HCV-CV and 70% of asymptomatic patients with circulating cryoglobulins had an immunologic response, with comparable reductions in cryocrit from 2.

Shorter hepatitis B immunoglobulin administration is not associated to hepatitis B virus recurrence when receiving combined prophylaxis after liver transplantation.

Background & Aims: The combination of hepatitis B immunoglobulin and a nucleos(t)ide analogues has markedly reduced the rate of hepatitis B virus recurrence after liver transplantation; however, the optimal duration of hepatitis B immunoglobulin has not been clarified. This lack of consensus perpetuates the use of different strategies. The aim of this study was to evaluate the risk factors associated to hepatitis B virus recurrence after liver transplantation in a large cohort of patients under different hepatitis B immunoglobulin regimens.

Impact of comorbidities on patient outcomes after interferon-free therapy-induced viral eradication in hepatitis C.

Background & Aims: Patients with advanced liver fibrosis remain at risk of cirrhosis-related outcomes and those with severe comorbidities may not benefit from hepatitis C (HCV) eradication. We aimed to collect data on all-cause mortality and relevant clinical events within the first two years of direct-acting antiviral therapy, whilst determining the prognostic capability of a comorbidity-based model.

Methods: This was a prospective non-interventional study, from the beginning of direct-acting antiviral therapy to the event of interest (mortality) or up to two years of follow-up, including 14 Spanish University Hospitals.

Correction: Neutrophil and Monocyte Function in Patients with Chronic Hepatitis C Undergoing Antiviral Therapy with Regimens Containing Protease Inhibitors with and without Interferon.

Neutrophil and Monocyte Function in Patients with Chronic Hepatitis C Undergoing Antiviral Therapy with Regimens Containing Protease Inhibitors with and without Interferon.

Real-life data showed an increased incidence of bacterial infections in patients with advanced liver disease receiving a protease inhibitor (PI)-containing antiviral regimen against hepatitis C (HCV). However, the causes of this event are unknown. We hypothesized that PIs might impair innate immune responses through the inhibition of proteases participating in the anti-bacterial functions of neutrophils and monocytes.

Virologic, Clinical, and Immune Response Outcomes of Patients With Hepatitis C Virus-Associated Cryoglobulinemia Treated With Direct-Acting Antivirals.

Background & Aims: Cryoglobulins (circulating immune complexes of polyclonal IgG, monoclonal IgM, and rheumatoid factor) are detected in the circulation of 40% to 60% of patients with chronic hepatitis C virus infection, and cryoglobulinemic vasculitis (CV) is observed in approximately 10% of patients. We aimed to assess the clinical and immune effects of direct-acting antiviral treatment.

Methods: We performed a prospective study of 64 patients with HCV infection with circulating cryoglobulins receiving direct-acting antiviral therapy at a single center in Barcelona, Spain, from January 2014 through April 2016.

Challenges in Special Populations: HIV/HCV Coinfection, Liver Transplantation and Patients with End-Stage Renal Disease.

Until recently, the combination of PEG-interferon and ribavirin (RBV) was the main treatment for all genotypes of chronic hepatitis C virus (HCV) infection. Sustained virological response (SVR) rates varied signixFB01;cantly across patient subgroups and the concept of 'special populations' emerged. Now, in the era of direct acting antivirals, with a better safety profile and higher efficacy rates, those patients with comorbidities or conditions that limited IFN-based antiviral treatment but with unmet medical needs have been considered for therapy again.

Antiviral treatment with sofosbuvir and simeprevir in a kidney transplant recipient with HCV-decompensated cirrhosis: viral eradication and removal from the liver transplant waiting list.

Hepatitis C positive kidney transplant (KT) recipients are a difficult-to-treat subpopulation. Interferon-based therapies are contraindicated (or at least not used) in KT patients, due to the risk of allograft rejection, its poor tolerability and the low rates of sustained virological response (SVR) achieved with these therapies. Nevertheless, the use of direct-acting antiviral drugs (DAAs) will certainly provide new opportunities for hepatitis C treatment in the KT setting.
