Objective: To investigate the diagnostic value of FibroTouch and FibroScan for the stage of primary biliary cirrhosis (PBC). Methods: A total of 66 PBC patients who visited our hospital from January 2014 to March 2016 were enrolled, and all the patients underwent liver biopsy and FibroTouch and FibroScan tests. Liver stiffness measurement (LSM) was used to assess fibrosis degree, and the receiver operating characteristic (ROC) curve was used to compare the cut-off values, sensitivities, and specificities of these two methods in determining fibrosis stage...

BACKGROUND: The prevalence of fatty liver underscores the need for non-invasive characterization of steatosis, such as the ultrasound-based controlled attenuation parameter (CAP). Despite good diagnostic accuracy, clinical use of CAP is limited due to uncertainty regarding optimal cut-offs and the influence of covariates. We therefore conducted an individual patient data meta-analysis. METHODS: A review of the literature identified studies containing histology controlled CAP data (M probe, vibration controlled transient elastography with Fibroscan) for grading of steatosis (S0-S3)...

BACKGROUND AND AIMS: The regression of liver fibrosis and portal hypertension (PH) and their influence on the natural history of compensated hepatitis C virus (HCV)-related cirrhosis has not been studied previously. Our objective was to evaluate the influence of sustained virologic response (SVR) on the portal pressure gradient (HVPG) and non-invasive parameters of PH and prognostic factors of response. METHODS: Sixteen patients with compensated HCV genotype 1-related cirrhosis with PH (HVPG > 6 mmHg) without beta-blocker therapy were considered as candidates for PEGα2a + RBV + BOC (48 weeks; lead-in and accepted stopping rules)...

Background and aims: Hepatic steatosis is the basis of non-alcoholic fatty liver disease (NALFD). Mere fat accumulation within hepatocytes is considered the mild form of NAFLD, but can progress in some patients to advanced steatohepatitis (NASH), which may lead to fibrosis, cirrhosis or hepatocellular carcinoma. However, even hepatic steatosis alone may be a risk factor for cardiovascular disease (CVD). Patients and methods: In the present real life study 106 patients from the outpatient clinic of the Department for Gastroenterology and Hepatology with either NAFLD (n = 60) or other typical diagnoses (n = 46) were included...

BACKGROUND: A certain proportion of hepatitis B virus (HBV)-infected patients with persistently normal alanine transaminase (ALT) levels have significant fibrosis. Using liver stiffness measurements (Fibroscan®) and laboratory data, including serum ALT, quantitative HBsAg (qHBsAg), and HBV DNA, we attempted to predict the natural histories of these patients. METHODS: Non-cirrhotic HBeAg-negative chronic hepatitis B patients with persistently normal ALT were followed up prospectively with the end points of HBsAg seroclearance and ALT elevation above the upper limit of normal...

BACKGROUND: Patients with hepatitis C virus (HCV) genotype 4 infection are poorly represented in clinical trials of 2nd-generation direct-acting antivirals (DAAs), and more data are needed to help guide treatment decisions. We still have even fewer data concerning liver transplant patients. Simeprevir (SIM) and sofosbuvir (SOF) combination is useful to treat this genotype. The aim of this study was to know the efficacy and safety of the combination SIM + SOF ± ribavirin (RBV) in a group of liver transplant patients with HCV genotype 4 infection in Spain in real life...

Data on markers of hepatitis C virus (HCV) disease in HIV-HCV-coinfected patients in resource-limited settings are scarce. We assessed HCV RNA, HCV genotype (GT), IL28B GT and liver fibrosis (FibroScan(®) ) in 480 HIV-infected patients with positive HCV antibody in four HIV treatment centres in South-East Asia. We enrolled 165 (34.4%) patients in Jakarta, 158 (32.9%) in Bangkok, 110 (22.9%) in Hanoi and 47 (9.8%) in Kuala Lumpur. Overall, 426 (88.8%) were male, the median (IQR) age was 38.1 (34.7-42.5) years, 365 (76...

Despite the rapidly increasing prevalence of non-alcoholic fatty liver disease (NAFLD) in type 2 diabetes (T2D), few treatment modalities are currently available. We investigated the hepatic effects of the novel thiazolidinedione (TZDs), lobeglitazone (Duvie) in T2D patients with NAFLD. We recruited drug-naïve or metformin-treated T2D patients with NAFLD to conduct a multicenter, prospective, open-label, exploratory clinical trial. Transient liver elastography (Fibroscan®; Echosens, Paris, France) with controlled attenuation parameter (CAP) was used to non-invasively quantify hepatic fat contents...

BACKGROUND AND AIM: There is currently no recommended time interval between non-invasive fibrosis measurements for monitoring chronic liver diseases. We determined how long a single liver fibrosis evaluation may accurately predict mortality, and assessed whether combining tests improves prognostic performance. METHODS: We included 1559 patients with chronic liver disease and available baseline liver stiffness measurement (LSM) by Fibroscan, APRI, FIB-4, Hepascore, and FibroMeter(V2G) ...

BACKGROUND AND AIMS: Pediatric use of liver transient elastography (TE) is attractive for its non-invasiveness, but reference values have not been established. We aimed to determine reference values for TE in children. METHODS: In pediatric patients (1 to 18 years), TE (FibroScan®) with an M probe was used for both liver stiffness measurement (LSM) and measurement of hepatic fat deposition by using a controlled attenuation parameter (CAP). The patients were divided into three relevant age groups: preschoolers (1 to 5 years), elementary school children (6 to 11 years), and adolescents (12 to 18 years)...

Although the availability of donor organs is limited, liver grafts from HCV-positive donors remained yet an obstacle, primarily because of limited therapeutic options for HCV reinfection and lower rates of graft and patient survival. However, new interferon-free regimens containing direct-acting antiviral agents have fewer adverse effects and better effectiveness, making HCV treatment feasible early after transplant. In 2014, we successfully used sofosbuvir and ribavirin to treat a patient with HCV genotype 3 cirrhosis who was listed for liver transplantation...

Since liver function is changed by chronic liver diseases, chronic liver disease can lead to different hemorheological alterations during the course of the progression. This study aims to compare alterations in whole blood viscosity in patients with chronic liver disease, focusing on the gender effect. Chronic liver diseases were classified into three categories by patient's history, serologic markers, and radiologic findings: nonalcoholic fatty liver disease (NAFLD) (n = 63), chronic viral hepatitis B and C (n = 50), and liver cirrhosis (LC) (n = 35)...

INTRODUCTION: In recent years, the frequency of human immunodeficiency virus (HIV) and hepatitis C (HCV) co-infection has increased, which is due to their common routes of transmission. HIV/chronic HCV co-infection aggravates the development of fibrosis and increases the risk of cirrhosis. The aim of the study was to evaluate the results of liver elastometry in patients of different ethnic groups with HIV/chronic HCV co-infection. METHODOLOGY: The study involved 49 Kazakh and 46 Russian patients with HIV/chronic HCV co-infection...
