Non-alcoholic fatty liver disease (NAFLD), the hepatic manifestation of obesity, is an emerging risk factor for hepatocellular carcinoma (HCC). Accumulating evidence has shown that chronic inflammation represents a plausible link between obesity and HCC, and that the pro-inflammatory cytokine IL-6 contributes to the development of obesity-related HCC. In the present study, we aimed to examine the therapeutic potential of the omega-3 polyunsaturated fatty acid, eicosapentaenoic acid (EPA), which exerts anti-inflammatory effects...

To explore the functional phenotype of liver macrophages in patients with autoimmune hepatitis (AIH). Compared with patients with nonalcoholic fatty liver disease (NAFLD) and chronic hepatitis B (CHB), the absolute CD(68)(+) cell count in patients with AIH was significantly higher (all P<0.05). It was positively correlated with ALT and IgG levels (the correlation coefficients 0.600 and 0.700, P=0.285 and 0.188 respectively). Additionally, compared with patients with NAFLD, the absolute iNOS positive cell count in patients with AIH and CHB were significantly higher (all P<0...

Aims: This study sought to compare mice bred to preferentially consume high amounts of alcohol (crossed-high alcohol preferring, cHAP) to c57BL/6 (C57) mice using a chronic-binge ethanol ingestion model to induce alcoholic liver disease (ALD). Methods: Male C57 and cHAP mice were randomized to a Lieber-DeCarli control (LDC) diet, Lieber-DeCarli 5% (v/v) ethanol (LDE) diet or free-choice between 10% (v/v) ethanol in drinking water (EtOH-DW) and DW. After 4 weeks mice were gavaged with either 9 g/kg maltose-dextrin (LDC+MD) or 5 g/kg EtOH (LDE+Binge, EtOH-DW+Binge)...

Nonalcoholic fatty liver disease is becoming the most common chronic liver disease in Western countries, and limited therapeutic options are available. Here we uncovered a role for intestinal hypoxia-inducible factor (HIF) in hepatic steatosis. Human-intestine biopsies from individuals with or without obesity revealed that intestinal HIF-2α signaling was positively correlated with body-mass index and hepatic toxicity. The causality of this correlation was verified in mice with an intestine-specific disruption of Hif2a, in which high-fat-diet-induced hepatic steatosis and obesity were substantially lower as compared to control mice...

Malnutrition has become a dangerously common problem in children with chronic liver disease, negatively impacting neurocognitive development and growth. Furthermore, many children with chronic liver disease will eventually require liver transplantation. Thus, this association between malnourishment and chronic liver disease in children becomes increasingly alarming as malnutrition is a predictor of poorer outcomes in liver transplantation and is often associated with increased morbidity and mortality. Malnutrition requires aggressive and appropriate management to correct nutritional deficiencies...

Visceral leishmaniasis is an endemic disease in many parts of world, and if untreated, it is a potentially life-threatening infectious disease. It is similar to chronic liver disease because of signs and symptoms such as fever, weight loss, hepatosplenomegaly, and pancytopenia. In this study, we present a case of visceral leishmaniasis, which is known to be a chronic hepatitis B infection, that was coincidentally diagnosed with liver biopsy. Visceral leishmaniasis should be considered as an infectious disease in the differential diagnosis of chronic liver diseases...

BACKGROUND: Chronic hepatitis B (CHB) cannot be completely eradicated due to the presence of covalently closed circular DNA (cccDNA) in the nuclei of infected hepatocytes. While quantification of intrahepatic cccDNA requires liver biopsies, serological markers can be non-invasive alternatives to reflect intrahepatic viral replicative activity. Recently, hepatitis B core-related antigen (HBcrAg) has been advocated as a novel serum marker for disease monitoring and prognostication of CHB...

BACKGROUND: With the development of direct-acting anti-virals (DAAs), almost all patients with chronic hepatitis C virus (HCV) infection can achieve sustained viral response (SVR). AIM: To evaluate the short-term risk of HCC among patients with SVR by DAAs, including those with cirrhosis or previous HCC. METHODS: This large-scale, multicentre cohort study included 1,675 consecutive patients who achieved SVR by treatment with interferon-free sofosbuvir-based regimens, divided into groups with (n = 152) or without previous HCC (n = 1,523)...

BACKGROUND: Hepatocellular carcinoma (HCC) is a leading cause of liver-related mortality in people living with HIV, where co-infection with hepatotropic viruses accelerates the course of chronic liver disease. AIM: To evaluate whether the albumin-bilirubin (ALBI) grade, a more accurate marker of liver dysfunction in HCC, might identify patients with progressive liver dysfunction in the context of HIV/hepatitis co-infection. METHODS: Using uni- and multi-variable analyses, we studied the albumin-bilirubin grade as a predictor of overall survival (OS) in a large, multi-center cohort of patients with HIV-associated HCC recruited from 44 centres in 9 countries within the Liver Cancer in HIV study group...

Bisphenol A (BPA) accumulates in the maturing gut and liver in utero and is known to alter gut bacterial profiles in offspring. Gut bacterial dysbiosis may contribute to chronic colonic and systemic inflammation. We hypothesized that perinatal BPA exposure-induced intestinal (and liver) inflammation in offspring is due to alterations in the microbiome and colonic metabolome. The 16S rRNA amplicon sequencing analysis revealed differences in beta diversity with a significant reduction in the relative abundances of short-chain fatty acid (SCFA) producers such as Oscillospira and Ruminococcaceae due to BPA exposure...

NAFLD is a chronic liver disease that affects a high proportion of the world's population which causes metabolic and hepatic damages. Rosa damascena Mill is traditionally used as a dietary supplement for liver disorders. This study was carried out to determine the beneficial effect of standardized extract of R. damascena on animal model of nonalcoholic fatty liver disease (NAFLD). NAFLD was induced by high-fat diet (HFD) in Wistar rats. HFD rats showed an increase (p < 0.05) in the plasma lipid levels of total cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL), and reduced the high-density lipoprotein (HDL) levels...

Cirrhosis is a common final pathway for most chronic liver diseases; representing an increasing burden worldwide and is associated with increased morbidity and mortality. Current evidence has shown that, after an initial injury, the immune response has a significant participation in the ongoing damage, and progression from chronic viral hepatitis (CVH) to cirrhosis, driving the activation and maintenance of main fibrogenic pathways. Among immune deregulations, those related to the subtype 17 of T helper lymphocytes (Th17)/interleukin-17 (IL-17) axis have been recognized as key immunopathological and prognostic elements in patients with CVH...

Hepatitis C virus (HCV) often leads to a chronic infection in the liver that may progress to steatosis, fibrosis, cirrhosis, and hepatocellular carcinoma (HCC). Several viral and cellular factors are required for a productive infection and for the development of liver disease. Some of these are long non-coding RNAs (lncRNAs) deregulated in infected cells. After HCV infection, the sequence and the structure of the viral RNA genome are sensed to activate interferon (IFN) synthesis and signaling pathways. These antiviral pathways regulate transcription of several cellular lncRNAs...

The development of tissue fibrosis in the context of a wound-healing response to injury is common to many chronic diseases. Unregulated or persistent fibrogenesis may lead to structural and functional changes in organs that increase the risk of significant morbidity and mortality. We will explore the natural history, epidemiology, and pathogenesis of fibrotic disease affecting the lungs, kidneys, and liver as dysfunction of these organs is responsible for a substantial proportion of global mortality. For many patients with end-stage disease, organ transplantation is the only effective therapy to prolong life...

Pruritus is a disabling symptom accompanying chronic cholestasis. In extreme cases, the refractory nature of pruritus can result in a need for invasive therapies including liver transplantation. The pathogenesis of pruritus in cholestatic disease is poorly understood. It may involve a specific neural pathway (similar to that associated with pain) regulated by several pruritogenic substances such as bile acids, opioids, serotonin, and the more recently identified lysophosphatidic acid. While the therapeutic management of cholestatic pruritus is well established in adults, there is no consensus in children, in light of the difficulty of conducting controlled clinical studies...

Common variable immunodeficiency (CVID), characterised by disordered B cell function, is one of the most common primary immunodeficiency disorders. Patients with CVID are at lifelong risk of recurrent infections, particularly of the respiratory and gastrointestinal tracts. Paradoxically, given their immunocompromised state, patients with CVID are also at significantly increased risk of autoimmune disorders, which are seen in almost 25% of cases. The authors report a 24-year-old female patient with CVID, manifested as severe hypogammaglobulinaemia with recurrent sinopulmonary infections and enterocolitis, who presented with transaminitis, chronic diarrhoea and haematemesis...

Chronic inflammation is increasingly recognized as an important component of tumorigenesis and metabolic diseases. The roles of microRNA149* (miRNA149*) in inflammation remain poorly understood. Here, we demonstrate that miR-149* is a suppressor of STAT3-mediated inflammation. MiR-149*(-/-) mice were generated with CRISPR/CAS9 technique. In a lipopolysaccharide (LPS)-induced inflammation model, miR-149*(-/-) mice show more severe liver injury and inflammation, compared with wild-type (WT) mice. MiR-149*(-/-) mice also displayed elevated messenger RNA (mRNA) levels of interleukin (IL)-6, inducible nitric oxide synthase (iNOS), complement C3 (C3) and IL-4 in response to LPS...

Background/Aim: Antiviral treatment for patients in HBeAg-positive chronic hepatitis B virus (HBV) infection is still controversial. We assessed whether antiviral treatment reduces liver disease progression in those patients. Methods: This study included consecutive patients that tested positive for HBeAg with an HBV DNA >20,000 IU/mL, ALT <40 IU/L and without evidence of cirrhosis in eight large-volume hospitals in Korea. The primary endpoint was the development of hepatocellular carcinoma (HCC) and the secondary endpoint was the development of cirrhosis...
