Between western European countries, the hepatitis C virus (HCV) endemic is highest in Italy. The main objective of this paper is to estimate the endemic diffusion of hepatitis C at the national level and by geographical area, with an extrapolation at the regional level and by uniform cohorts of subjects (by sex and year of birth). The secondary objective is a stratification by gravity of the estimated statistical figures to provide an overview of possible targets of the new anti-HCV treatments.PubMed and the Cochrane Library were searched for relevant Italian populations studies regarding HCV prevalence...

BACKGROUND: Noninvasive assessment of liver fibrosis has important clinical significance. Different techniques including two-dimensional shear-wave elastography (2D SWE) and real-time tissue elastography (RTE) are reported to be useful for the noninvasive diagnosis of hepatic fibrosis. All these techniques are affected by many factors. How to choose a reasonable method needs further studies. PURPOSE: This study was conducted to comparatively assess the diagnostic performance of 2D SWE and RTE in patients with Chronic Hepatitis B (CHB) and influence of inflammation on the stiffness values obtained by both techniques, so as to objectively assess the reasonable choice between these 2 elastography techniques for noninvasive assessment of hepatic fibrosis in clinical practice...

Staging fibrosis is crucial for the prognosis and to determine the rapid need of treatment in patients with chronic hepatitis B (CHB) and C (CHC). The expression of 13 fibrosis-related microRNAs (miRNAs) (miR-20a, miR-21, miR-27a, miR-27b, miR-29a, miR-29c, miR-92a, miR-122, miR-146a, miR-155, miR-221, miR-222, and miR-224) was analyzed in 194 serums and 177 liver biopsies of patients with either CHB or CHC to develop models to diagnose advanced fibrosis and cirrhosis (Metavir F3-F4). In CHB patients, the model (serum miR-122, serum miR-222, platelet count and alkaline phosphatase) was more accurate than APRI and FIB-4 to discriminate in between mild and moderate fibrosis (F1-F2) and F3-F4 (AUC of CHB model: 0...

Introduction: According to the guidelines, the viral load of 2,000 IU/mL is considered the level to differentiate between inactive carriers and HBeAg(-) chronic hepatitis B patients. Even so, liver damage may be present in patients with lower viral load levels, mainly related to regional variations. This study aims to verify the presence of liver injury in patients with viral load below 2,000 IU/mL. Methods: Patients presenting HBsAg(+) for more than six months, Anti-HBe(+)/HBeAg(-), viral load below 2,000 IU/mL and serum ALT levels less than twice the upper limit of normality underwent liver biopsy...

Fibrosis progression is common in hepatitis C. Both host and viral factors influence its natural history. Liver fibrosis is a key predictive factor for advanced disease including endpoints such as liver failure, cirrhosis and hepatocellular carcinoma (HCC). METAVIR fibrosis stages F3-F4 have been considered as the threshold for antiviral therapy. However, this aspect is controversial after the advent of new direct-acting antivirals (DAAs) because they show an excellent efficacy and safety profile. Moreover, in the DAA era, fibrosis stage seems not to be a predictive factor of a sustained virological response (SVR)...

Although Metavir and Fibrosis-4 (FIB-4) scores are typically used to assess the severity of liver fibrosis, the relationship between these scores and patient outcome in hepatocellular carcinoma (HCC) is unclear. The aim of this study was to evaluate the prognostic value of the severity of hepatic fibrosis in HBV-related HCC patients after curative resection. We examined the prognostic roles of the Metavir and preoperative FIB-4 scores in 432 HBV-HCC patients who underwent curative resection at two different medical centers located in western (Chongqing) and eastern (Shanghai) China...

OBJECTIVE: Liver fibrosis is traditionally graded into categorical stages with cirrhosis as the highest stage. However, cirrhosis stage may vary between individuals widely in terms of the amount of fibrosis which is not assessed by traditional staging systems. We aimed to utilise visual morphometry to quantify the amount of fibrosis in liver biopsy and compare how non-invasive methods of quantifying liver fibrosis correlated with histological measures. MATERIALS AND METHODS: Liver biopsy specimens from 115 consecutive chronic liver disease patients were assessed by a single pathologist for fibrosis stage by the Clinical Research Network and METAVIR systems as well as percentage fibrosis by visual morphometry...

Acoustic structure quantification (ASQ) is a recently developed technique widely used for detecting liver fibrosis. Ultrasound Nakagami parametric imaging based on the Nakagami distribution has been widely used to model echo amplitude distribution for tissue characterization. We explored the feasibility of using ultrasound Nakagami imaging as a model-based ASQ technique for assessing liver fibrosis. Standard ultrasound examinations were performed on 19 healthy volunteers and 91 patients with chronic hepatitis B and C (n = 110)...

: Hepatitis C virus (HCV) recurrence after liver transplant (LT) is associated with worse outcomes. Ledipasvir and sofosbuvir (LDV/SOF) has been approved for HCV treatment after LT, but there is limited data on the effectiveness and safety of LDV/SOF in the "real world" setting. This multi-center study is the largest report to date, on the effectiveness and safety of LDV/SOF in the post-LT setting. Two hundred and four patients (72% male, 68% Caucasian, 66% genotype 1a, 21% METAVIR F3-F4, 49% treatment-experienced) were treated with LDV/SOF...

OBJECTIVES: Transient elastography (TE) measures liver stiffness to assess fibrosis. Studies in adults have shown that inflammation increases stiffness, leading to an overestimation of fibrosis. We investigated the contribution of inflammation to liver stiffness measurements (LSM) in children/ young adults. METHODS: This was a cohort analysis of children/ young adults who underwent TE within 1 year of liver biopsy. ALT was obtained within 30d of the biopsy and LSM...
