Chronic hepatitis C (CHC) is a leading cause of hepatic fibrosis and cirrhosis. The level of fibrosis is traditionally established by histology and prognosis is estimated using fibrosis progression rates (FPRs; annual probability of progressing across histological stages). However, newer non-invasive alternatives are quickly replacing biopsy. One alternative, transient elastography (TE), quantifies fibrosis by measuring liver stiffness (LSM). Given these developments, the purpose of this study was (1) to estimate prognosis in treatment-naïve CHC patients using TE-based liver stiffness progression rates (LSPR) as an alternative to FPRs and (2) to compare consistency between LSPRs and FPRs...

Activation of the adiponectin (APN) signaling axis retards liver fibrosis. However, understanding of the role of AdipoR1 and AdipoR2 in mediating this response is still rudimentary. Here, we sought to elucidate the APN receptor responsible for limiting liver fibrosis by employing AdipoR1 and AdipoR2 knock-out mice in the carbon tetrachloride (CCl4) model of liver fibrosis. In addition, we knocked down receptor function in primary hepatic stellate cells (HSCs) in vitro. Following the development of fibrosis, AdipoR1 and AdipoR2 KO mice had no quantitative difference in fibrosis by Sirius red staining...

Treatment with recently-developed interferon-free oral regimens combining direct-acting antiviral agents (DAAs) results in the elimination of hepatitis C virus (HCV) in almost all chronic hepatitis C (CHC) patients. In the era of DAAs, surveillance of hepatocellular carcinoma (HCC) after eradication of HCV by anti-HCV therapy is particularly important. As is well known, an advanced state of hepatic fibrosis is the major risk factor for developing HCC. Therefore, an increased understanding of various factors associated with disease progression and development of HCC in CHC patients is essential for implementing personalized treatment and surveillance of disease progression and HCC...

Inhibition of microRNA-21 (miR-21) prevents necroptosis in the mouse pancreas. Necroptosis contributes to hepatic necro-inflammation in the common bile duct ligation (BDL) murine model. We aimed to evaluate the role of miR-21 in mediating deleterious processes associated with cholestasis. Mechanistic studies established a functional link between miR-21 and necroptosis through cyclin-dependent kinase 2-associated protein 1 (CDK2AP1). miR-21 expression increased in the liver of primary biliary cholangitis (PBC) patients and BDL wild-type (WT) mice at both 3 and 14 days...

BACKGROUND: Liver fibrosis shows a continuously increasing trend worldwide, due to alcohol abuse, obesity, and, to a lesser extent, chronic hepatitis B and C. Biopsy is still considered the "gold standard" for diagnosis of liver fibrosis. However, it has a number of limitations, such as invasiveness, high cost, need for specialists to conduct and interpret biopsy results, risk of complications, inability to dynamically monitor the pathological process, low patient compliance, and uneven fibrosis distribution...

Evaluation of the extent and progression of liver fibrosis and cirrhosis is of critical importance in the management and prognosis of patients with chronic hepatitis B. Due to the limitation of liver biopsy, non-invasive methods, especially liver stiffness measurement (LSM) by vibration controlled transient elastography, have been developed and widely applied for liver fibrosis assessment. LSM aims to reduce, but not to substitute, the need for liver biopsy for fibrosis/cirrhosis diagnosis. While LSM may have potential utility in monitoring treatment response, its applications in prediction of liver complications in terms of portal hypertension and esophageal varices, as well as disease prognosis, have been gradually validated...
