BACKGROUND & AIMS: Recently we have shown that cartilage oligomeric matrix protein (COMP), a fibrillar collagen assembly regulator, is strongly associated with cirrhosis and hepatocellular carcinoma progression. Therefore, we assessed whether serum COMP levels can be used as a non-invasive fibrosis marker in patients with chronic viral hepatitis (CVH) and compared this marker with standard methods for disease stage assessment [histology, transient elastography (TE), APRI, FIB-4]. METHODS: Sera from 116 CVH patients, 66 HBV [24 female; median age 53(22-76)] and 50 HCV [21 female; median age 48...

BACKGROUND: Cocaine and crack use has been associated with HIV and HCV infections, but its consequences on HCV progression have not been well established. We analyzed the impact of cocaine/crack use on liver fibrosis progression in a cohort of HIV-HCV co-infected patients. METHODS: A Canadian multicenter prospective cohort study followed 1238 HIV-HCV co-infected persons every 6 months between 2003 and 2013. Data were analyzed from 573 patients with positive HCV RNA, not on HCV treatment, without significant liver fibrosis (AST-to-Platelet Ratio Index (APRI) <1...

OBJECTIVES: Autoimmune hepatitis (AIH) is a relatively rare cause of hepatic dysfunction, which can lead to acute liver failure (ALV) and cirrhosis if not treated. The performance of transient elastography (TE) compared to liver biopsy has been evaluated in many liver diseases. The aim of the present study was to evaluate the performance of TE and other non-invasive markers for liver fiibrosis in patients with biopsy-proven AIH. METHODS: Fifty-three patients who were treated at the department of gastroenterology and hepatology of the University Clinic Essen from 2008 to 2013 included in this retrospective study...

BACKGROUND AND OBJECTIVE: Epigenetics contributes to the outcome of chronic hepatitis B virus (HBV) infection. However, the role of methyl-CpG binding domain (MBD) family in the natural history of chronic hepatitis B (CHB) has not been demonstrated. It is aimed to investigate the dynamic expression of MBD family and assess the potential association of MBD family in the progression of CHB. METHODS: Quantitative real-time polymerase chain reaction (RT-PCR) was used to determine the mRNA levels of MBD family in peripheral blood mononuclear cells (PBMCs) from 223 patients with CHB as training cohort, 146 patients with CHB as validation cohort [immune-tolerant (IT), immune clearance (IC), non/low-replicative (LR) and HBeAg negative hepatitis (ENH)], and 14 healthy controls (HCs)...

The spectral contaminants are inevitable during micro-Raman measurements. A key challenge is how to remove them from the original imaging data, since they can distort further results of data analysis. Here, we propose a method named "automatic pre-processing method for Raman imaging data set (APRI)", which includes the adaptive iteratively reweighted penalized least-squares (airPLS) algorithm and the principal component analysis (PCA). It eliminates the baseline drifts and cosmic spikes by using the spectral features themselves...

OBJECTIVES: Liver biopsy remains the reference standard for the assessment of liver fibrosis, but this procedure is invasive and can lead to complications. Thus, studies to determine the optimal noninvasive test are warranted. This study compared several noninvasive tests and their combinations for evaluating liver fibrosis stages in patients with chronic hepatitis B. METHODS: The shear wave velocity (SWV) and laboratory indicators were collected from 174 patients with chronic hepatitis B...

BACKGROUND: Liver fibrosis and its sequel cirrhosis represent a major health care burden, and assessment of fibrosis by biopsy is gradually being replaced by noninvasive methods. In clinical practice, the determination of fibrosis stage is important, since patients with advanced fibrosis have faster progression to cirrhosis and antiviral therapy is indicated in these patients. AIMS: To assess the role of transient elastography (TE) and compare it with APRI and FIB4 for predicting liver fibrosis and assessing the effect of host and viral factors on fibrosis and treatment outcome in CHC patients...

AIM: To assess disease-specific circulating microRNAs (miRNAs) in non-alcoholic steatohepatitis (NASH) patients. METHODS: A total of 111 biopsy-proven non-alcoholic fatty liver disease (NAFLD) or chronic hepatitis B (CHB) patients and healthy controls from mainland China were enrolled to measure their serum levels of miR-122, -125b, -146b, -16, -21, -192, -27b and -34a. The correlations between serum miRNAs and histological features of NAFLD were determined. The diagnostic value of miRNA in NASH and significant fibrosis was analyzed and compared with that of cytokeratin-18 (CK-18), fibrosis-4 (FIB-4), and aspartate aminotransferase to platelet ratio index (APRI), respectively...
