Adipocytokines play an important role in adipose tissue homeostasis, especially in obesity-associated disorders such as non-alcoholic fatty liver and their complications including hepatocellular carcinoma (HCC). Although visfatin is an adipocytokine highly expressed in visceral fat that has been demonstrated to play a critical role in the progression of human malignancies, little is known about the role of visfatin in HCC associated with chronic hepatitis C virus (HCV) and hepatitis B virus (HBV) infection...

BACKGROUND & AIM: Although the ideal end point for antiviral treatment in patients with chronic hepatitis B (CHB) is loss of HBsAg, the typical clinical end points are HBeAg seroconversion in HBeAg-positive patients and long-term DNA suppression in HBeAg-negative patients. We evaluated the long-term antiviral response after cessation of lamivudine treatment in CHB patients. METHODS: A total of 157 patients who had discontinued lamivudine between 1997 and 2014 were enrolled (97 HBeAg-positive and 60 HBeAg-negative CHB patients)...

BACKGROUND: There are no approved treatments for liver fibrosis. To aid development of anti-fibrotic therapies, non-invasive biomarkers that can identify patients with progressive fibrosis and that permit monitoring of the response to anti-fibrotic therapy are much needed. METHODS: Samples from a phase II anti-fibrotic trial of the glitazone farglitazar in patients with advanced hepatitis C, with matched follow-up liver biopsies, and from a phase III study of balaglitazone in late stage type 2 diabetics (BALLET study), were analysed for serological Pro-C3 levels in conjunction with other disease parameters...

BACKGROUND: Plasminogen activator inhibitor-1 (PAI-1) is the primary inhibitor of the endogenous fibrinolytic system and is known to be increased in obesity, insulin resistance and non-alcoholic fatty liver disease (NAFLD). We previously demonstrated that PAI-1 levels were closely related to the amount of hepatic steatosis in children. OBJECTIVES: The aim of this study was to characterize plasma PAI-1 in relationship to severity of inflammation and fibrosis, as well as to plasma lipids in children with NAFLD...

Approximately 70% of kidney transplant recipients are non-responders to conventional hepatitis B virus (HBV) vaccines. We examined whether Fendrix(™) , an HBV vaccine containing 3-O-desacyl-4'-monophosphoryl lipid A (MPL) as adjuvant, could induce HBV immunity in these patients and compared their vaccination efficacy with healthy controls tested previously by the same assays. We selected 35 kidney transplant recipients who had been vaccinated at least thrice against HBV but had never displayed anti-HBs antibodies...

Tissue transglutaminase 2 enzyme plays a diverse role in intracellular and extracellular functioning. Aberrant expression of anti-TG2 antibody has recently been proposed for extraintestinal identification of celiac disease (CeD), but its utility is questionable. To examine whether anti-TG2 immunohistochemical (IHC) staining can be of diagnostic value in identifying extraintestinal involvement in CeD, tissue blocks of patients with IgA nephropathies (IgAN), minimal change disease, membranous glomerulonephritis, membrano-proliferative glomerulonephritis, normal kidney, intestinal biopsies from CeD, tropical sprue, nonspecific duodenitis, and inflammatory bowel disease; liver biopsies from patients with chronic hepatitis B and C, acute liver failure (ALF), and CeD-associated liver diseases were retrieved and subjected to IHC staining for anti-tissue transglutaminase 2 enzyme...

BACKGROUND: Because whether hepatitis B virus (HBV) infection increases the risk of type 2 diabetes mellitus (T2DM) has been a controversial topic, pair-wise and network meta-analyses of published literature were carried out to accurately evaluate the association between different phases of HBV infection and the risk of T2DM. METHODS: A comprehensive literature retrieval was conducted from the Pubmed, Embase, Cochrane Library, Chinese Database to identify epidemiological studies on the association between HBV infection and the risk of T2DM that were published from 1999 to 2015...

: Hepatitis C virus (HCV) infection is associated with lymphoproliferative disorders and B-cell non-Hodgkin lymphomas (B-NHLs). Evaluation of the efficacy and safety profiles of different antiviral therapies in HCV patients with B-NHL is warranted. METHODS: First, we evaluated the sustained virologic response (SVR) and safety of Peg-interferon-alpha (Peg-IFN) + ribavirin +/- first protease inhibitors (PI1s) therapy in 61 HCV patients with B-NHL enrolled in a nationwide observational survey compared with 94 matched HCV-infected controls without B-NHL...

Chronic hepatitis B infection (CHB) is a known risk factor for malignancy. Unlike hepatocellular carcinoma (HCC), less is known about the risk of non-HCC malignancy. However, epidemiology and pathologic evidence suggests a strong association between non-Hodgkin lymphoma and CHB. Data regarding the risk of other malignancies, such as pancreatic adenocarcinoma and intrahepatic cholangiocarcinoma, are mixed. Surveillance and appropriate treatment of infection and malignancy in these patients is essential. Further study of these associations is needed and may bring new insights in the pathogenesis and treatment of these diseases...

Since the sequence of hepatitis E virus (HEV) was determined from a patient with enterically transmitted non-A, non-B hepatitis in 1989, similar sequences have been isolated from many different animals, including pigs, wild boars, deer, rabbits, bats, rats, chicken, and trout. All of these sequences have the same genomic organization, which contains open reading frames (ORFs) 1, 2, and 3, although their genomic sequences are variable. Some have proposed that they be classified as new family, Hepeviridae, which would be further divided into different genera and species according to their sequence variability...

MicroRNAs (miRNAs) inhibit or improve the malignant progression of hepatocellular carcinoma (HCC). We previously reported that compared to health controls, patients with liver cirrhosis present the highest levels of circulating miR-885-5p, followed by those with chronic hepatitis B and those with HCC. However, the molecular involvement of miR-885-5p in HCC metastasis is presently unclear. Here, we demonstrated that the expression of miR-885-5p negatively correlated with the invasive and metastatic capabilities of human HCC tissue samples and cell lines...

BACKGROUND: Portal vein thrombosis (PVT) is due to many risk factors, but its pathogenesis is still not clearly understood. To identify the risk factors for PVT, we analyzed the clinical characteristics and complications associated with PVT in cirrhotic patients. METHODS: We studied patients with liver cirrhosis who were admitted to our unit from April 2009 to December 2014. The patients were divided into the PVT and non-PVT groups, and were compared by variables including gender, age, the etiology of cirrhosis, stage of cirrhosis, complications, imaging, and treatment...

Fatty liver, or hepatic steatosis, is an alarmingly common pathology in western societies, in large part because if left unheaded it can lead to life-threatening forms of non-alcoholic fatty liver disease, including non-alcoholic steatohepatitis, fibrosis, cirrhosis and hepatocellular carcinoma. As such, it is essential that we attain a greater understanding of the pathways that control energy partitioning in the liver, and ultimately how they are impacted by environmental factors. Herein, we define the essential requirement for a member of the RAB-like clade of small GTPases, RABL2, in fatty acid metabolism including in microtubule-associated mitochondrial movement within the liver...
