Purpose To determine the relationship between hepatic uptake at preoperative fluorine 18 (18F) fluorocholine combined positron emission tomography (PET) and computed tomography (CT) and the histopathologic features of chronic liver disease in patients with Child-Pugh class A or B disease who are undergoing hepatic resection for liver cancer. Materials and Methods Forty-eight patients with resectable liver tumors underwent preoperative 18F fluorocholine PET/CT. Mean liver standardized uptake value (SUVmean) measurements were obtained from PET images, while histologic indexes of inflammation and fibrosis were applied to nontumor liver tissue from resection specimens...

The Kogelberg Biosphere Reserve in the Cape Floral Kingdom in South Africa is known for its unique plant biodiversity. The potential presence of unique microbial and viral biodiversity associated with this unique plant biodiversity led us to explore the fynbos soil using metaviromic techniques. In this study, metaviromes of a soil community from the Kogelberg Biosphere Reserve has been characterised in detail for the first time. Metaviromic DNA was recovered from soil and sequenced by Next Generation Sequencing...

The aim of the present study was to evaluate the predictors for advanced liver fibrosis in patients with chronic hepatitis B virus (HBV) infection with persistently normal alanine aminotransferase (PNALT), or persistently or intermittently mildly elevated ALT (PIEALT). A total of 305 patients were included in the present study. Liver biopsies were evaluated using the METAVIR scoring system. Liver stiffness (LS) was measured using Fibroscan. Multivariate logistic regression and the area under the receiver operating characteristic curve (AUROC) were used to examine the diagnostic value of the predictors for advanced liver fibrosis...

METHODS: Twenty-nine rabbit models of CCl4-induced liver fibrosis were established and six untreated rabbits served as controls. T1ρ MR imaging and 2D real-time SWE examination were performed at 2, 4, 6, 8, 10, and 12 weeks. T1ρ values and liver stiffness (LS) values were measured. Fibrosis was staged according to the METAVIR scoring system...

BACKGROUND AND STUDY AIM: Transient elastography is widely used to assess fibrosis stage in chronic hepatitis C (CHC). We aimed to establish and validate different transient elastography cut-off values for significant fibrosis and cirrhosis in CHC genotype 4 patients. PATIENTS AND METHODS: The data of 100 treatment-naive CHC patients (training set) and 652 patients (validation set) were analysed. The patients were subjected to routine pretreatment laboratory investigations, liver biopsy and histopathological staging of hepatic fibrosis according to the METAVIR scoring system...

BACKGROUND Autoimmune hepatitis (AIH) is an immune-mediated chronic liver disease that can lead to severe fibrosis and cirrhosis. Transient elastography (TE, FibroScan) can assess the fibrotic stages of chronic liver diseases by liver stiffness measurement (LSM). Studies on the diagnostic accuracy of FibroScan for the detection of fibrosis in AIH patients are still limited. MATERIAL AND METHODS This study enrolled 108 AIH patients who underwent liver biopsies. Using the METAVIR scoring system as the reference, Spearman's rank correlation was performed to explore the relationship between the markers and stages of fibrosis...

BACKGROUND/AIMS: Long-term follow-up studies validating the clinical benefit of sustained virological response (SVR) in people with chronic hepatitis C (CHC) infection are lacking. Our aim was to identify rates and predictors of liver fibrosis progression in a large, well characterized cohort of CHC patients in whom paired liver fibrosis assessments were performed more than 10 years apart. METHODS: CHC patients who had undergone a baseline liver biopsy pre-2004 and a follow up liver fibrosis assessment more than 10 years later (biopsy or liver stiffness measurement (LSM) using transient elastography [FibroScan]) were identified...

BACKGROUND: Liver fibrosis is the most important prognostic factor in chronic hepatitis C virus (HCV) patients, and Egypt shows the highest worldwide HCV prevalence with genotype-4 pre-dominance. The aim of this study was to investigate the degree of liver stiffness measurement (LSM) improvement after successful HCV eradication. PATIENTS AND METHODS: The study included 84 chronic HCV Egyptian patients, and was conducted at Qena University Hospital from November 1, 2015 till October 31, 2016...

BACKGROUND AND AIM: Quantitative digital imaging analysis to evaluate liver fibrosis is accurate, but its clinical use is limited by its high cost and lack of standardization. We aimed to validate an inexpensive digital imaging analysis technique for fibrosis quantification in chronic hepatitis B patients. MATERIAL AND METHODS: In total, 142 chronic hepatitis B patients who underwent liver biopsy and analysis of serum fibrosis markers were included. Images of Sirius red stain sections were captured and processed using Adobe Photoshop CS3 software...

Background and rationale for the study. Liver biopsy is the golden standard for staging liver fibrosis, but it may be accompanied by complications. Because of this complication, the aim of this study is to evaluate a simple noninvasive score to assess hepatic fibrosis in chronic hepatitis C genotype 4 patients which is very may have an important in diagnosis and therapeutic decision. This score [HA vascular (HAV) score] is a combination of direct markers [hyaluronic acid (HA) and vascular endothelial growth factor (VEGF)] and indirect markers [aspartate aminotransferase (AST)/alanine aminotransferase (ALT) ratio (AAR)]...

BACKGROUND: Liver MR elastography (MRE) is available for the noninvasive assessment of liver fibrosis; however, no previous studies have compared the diagnostic ability of MRE with that of liver biopsy. PURPOSE: To compare the diagnostic accuracy of liver fibrosis staging between MRE-based methods and liver biopsy using the resected liver specimens as the reference standard. STUDY TYPE: A retrospective study at a single institution. POPULATION: In all, 200 patients who underwent preoperative MRE and subsequent surgical liver resection were included in this study...

OBJECTIVES: Our study sought to determine the distribution of hepatitis C virus (HCV)-genotypes among patients attending two tertiary care hospitals in Benghazi and Tripoli, Libya, and correlate this with patient's characteristics, viral load, and degree of fibrosis. METHODS: We conducted a retrospective study of 286 HCV-RNA positive Libyan patients referred from different health care facilities in east and west Libya for specific HCV treatment. HCV genotyping was carried out by gene amplification...

The presence of significant fibrosis is an indicator for liver disease staging and prognosis. The aim of the study was to determine reproducibility of real-time shear wave elastography using a hepatic biopsy as the reference standard to identify patients with chronic liver disease. Forty patients with chronic liver disease and 12 normal subjects received shear wave elastography performed by skilled operators. Interoperator reproducibility was studied in 29 patients. Fibrosis was evaluated using the Metavir score...

The adenosine deaminase acting on RNA (ADAR1) gene is an interferon-stimulated gene involved in liver injury protection. Our aim was to analyze the association of polymorphisms within this gene with the severity of liver disease in European HIV/HCV-coinfected patients. We performed a cross-sectional study in 220 patients that underwent a liver biopsy. Five SNPs in the ADAR1 gene (rs1127326, rs1127317, rs1127314, rs1127313, rs2229857) were genotyped by GoldenGate assay. The outcome variables were fibrosis stage and necroinflammatory activity grade by METAVIR-score, aspartate aminotransferase to platelet ratio index (APRI), FIB-4 index, and fibrosis progression rate (FPR)...

BACKGROUND: Oral DAA have demonstrated high efficacy as treatment of hepatitis C. However, the presence of resistance-associated substitutions (RAS) at baseline has occasionally been associated with impaired treatment response. Herein, we examined the impact of baseline RAS at the HCV NS5A gene region on treatment response in a real-life setting. METHODS: All hepatitis C patients treated with DAA including NS5A inhibitors at our institution were retrospectively examined...

INTRODUCTION: Hepatitis C Virus (HCV) relies on host lipids for its life cycle contributing to lipid abnormalities and hepatic steatosis. Disease progression is influenced by viral factors interacting with host immune and metabolic pathways. The significance of serum lipids for Chronic Hepatitis C (CHC) assessment is not clearly established yet. AIM: Our aim was to investigate serum lipids' association with stage of liver fibrosis, steatosis and genotypes in patients with CHC...
