OBJECTIVE: Visceral adiposity index (VAI) is a mathematical model associated with cardiometabolic risk in adults, but studies on children failed to support this association. Our group has proposed a pediatric VAI model using pediatric ranges, but it has not yet been evaluated and needs further adjustments. The objective of this study was to further adjust the proposed pediatric VAI by age, creating a new pediatric metabolic index (PMI), and assess the correlation of the PMI with insulin resistance indexes and hepatic enzymes...

Psoriasis is a chronic inflammatory disease of the skin affecting approximately 2% of the world's population. Systemic treatments, including methotrexate and cyclosporin, are associated with potential hepatotoxicity, due to either direct liver damage or immunosuppression or both immunomediated and a direct liver injury; therefore, treatment of patients with psoriasis poses a therapeutic challenge. The aim of this minireview is to help clinicians in the management of psoriatic patients who develop signs of liver dysfunction...

The development of nonalcoholic fatty liver disease (NAFLD) is caused by the steatosis of hepatocytes, which induces oxidative stress (OS). Thus, OS has an important role in the development of NAFLD. In the present study, the L-02 hepatocyte cell line was used to develop a steatosis cell model. The best model was determined using an MTT assay and the triglyceride levels. Model cells were treated with high concentrations of uric acid (UA; 0, 5, 10, 20 and 30 mg/dl) for 24, 48, 72 and 96 h. Indicators of oxidation were then measured, which included total superoxide dismutase (SOD), malonaldehyde (MDA) and reduced glutathione (GSH), and the transcriptional and translational levels of SOD1 and γ-glutamate-cysteine ligase (γ-GCLC) were also determined...

Scutellaria baicalensis has been reported to improve the lipid metabolism of high-fat diet-induced liver dysfunction, but direct evidence is rare. This study aimed to explore the effects and mechanisms of S. baicalensis and its major constituent baicalin on hepatic lipotoxicity. KK-Ay mice and orotic acid (OA)-induced nonalcoholic fatty liver disease (NAFLD) rats were used to evaluate lipid metabolism regulatory effects. Sodium oleate-induced triglyceride-accumulated HepG2 cells were used for the mechanism study, pretreated with or without compound C or STO-609 or transfected with liver kinase B1 (LKB1) siRNA...

AIMS: While several non-invasive clinical/metabolic scores have been designed to predict the presence of nonalcoholic steatohepatitis (NASH), none was specifically validated in patients with T2DM. We aimed to assess the utility of existing metabolomics scores to classify liver disease in patients with T2DM. MATERIALS AND METHODS: A total of 220 patients with T2DM were recruited. Patients underwent routine lab tests, a liver proton magnetic resonance spectroscopy (1 H-MRS), a 75-gram OGTT, and a liver biopsy if they had NAFLD by1 H-MRS...

Arctigenin (ATG), a lignin extracted from Arctium lappa (L.), exerts antioxidant and anti-inflammatory effects. We hypothesized that ATG exerts a protective effect on hepatocytes by preventing nonalcoholic fatty liver disease (NAFLD) progression associated with lipid oxidation-associated lipotoxicity and inflammation. We established an in vitro NAFLD cell model by using normal WRL68 hepatocytes to investigate oleic acid (OA) accumulation and the potential bioactive role of ATG. The results revealed that ATG inhibited OA-induced lipid accumulation, lipid peroxidation, and inflammation in WRL68 hepatocytes, as determined using Oil Red O staining, thiobarbituric acid reactive substance assay, and inflammation antibody array assays...

Nonalcoholic fatty liver disease (NAFLD) is the hepatic manifestation of the obesity epidemic. Recent studies have clearly shown that the stage of fibrosis in adults with NAFLD is the most important histological feature in long-term outcomes and the development of liver-related complications. Despite the paucity of data regarding the natural history of pediatric NAFLD, its progression to cirrhosis and end-stage liver disease requiring liver transplantation is well documented. Given the high prevalence of NAFLD in children and adults, there is an urgent need to find safe and cost-effective alternatives to biopsy to determine the stage of liver fibrosis...

Nonalcoholic fatty liver disease (NAFLD) is a kind of liver lipid synthesis and degradation imbalance related with metabolic syndrome. Celecoxib shows the function of ameliorating NAFLD, but the underlying mechanisms remain unknown. Here, we discuss the possible mechanisms of celecoxib alleviating NAFLD by restoring autophagic flux. Lipids were accumulated in L02 cells treated with palmitate as well as SD rats fed with high-fat diet. Western blot showed that LC3 II/I was higher and p62 was lower on the early stage of steatosis while on the late stage both of them were higher, indicating that autophagic flux was activated on the early stage of steatosis, but blocked on the late stage...

Excess lipid accumulation is an early signature of nonalcoholic fatty liver disease (NAFLD). Although liver receptor homolog 1 (LRH-1) (encoded by NR5A2) is suppressed in human NAFLD, evidence linking this phospholipid-bound nuclear receptor to hepatic lipid metabolism is lacking. Here, we report an essential role for LRH-1 in hepatic lipid storage and phospholipid composition based on an acute hepatic KO of LRH-1 in adult mice (LRH-1AAV8-Cre mice). Indeed, LRH-1-deficient hepatocytes exhibited large cytosolic lipid droplets and increased triglycerides (TGs)...

Pioglitazone (PIO) has been reported to be effective for nonalcoholic fatty liver disease (NAFLD) and alogliptin (ALO) may have efficacy against NAFLD progression in patients with type 2 diabetes mellitus (T2DM). The present study examined the effectiveness of ALO in a rodent model of NAFLD and diabetes mellitus. KK‑Ay mice were used to produce an NAFLD model via administration of a choline‑deficient (CD) diet. To examine the effects of alogliptin, KK‑Ay mice were provided with a CD diet with 0.03% ALO and/or 0...

BACKGROUND & AIMS: Nonalcoholic fatty liver disease is common in HIV, but there are no approved therapies. The aim of this open-label proof-of-concept study was to determine the effect of the mineralocorticoid receptor antagonist eplerenone on hepatic fat in HIV-infected patients with hepatic fat ≥ 5% by magnetic resonance spectroscopy. METHODS: Five subjects received eplerenone (25 mg daily x 1 week followed by 50 mg daily x 23 weeks). Laboratory tests were done at each visit, and the primary endpoint, change in hepatic fat content, was determined by MRI spectroscopy at baseline and week 24...

Increasingly, evidence suggests that exposure to maternal obesity creates an inflammatory environment in utero , exerting long-lasting postnatal signatures on the juvenile innate immune system and microbiome that may predispose offspring to development of fatty liver disease. We found that exposure to a maternal Western-style diet (WD) accelerated fibrogenesis in the liver of offspring and was associated with early recruitment of proinflammatory macrophages at 8-12 weeks and microbial dysbiosis as early as 3 weeks of age...

Insulin resistance is a key risk factor in the progression of nonalcoholic fatty liver disease (NAFLD) and may lead to liver fibrosis. Natural killer (NK) cells are thought to exert an antifibrotic effect through their killing of activated hepatic stellate cells (HSCs). Here, we investigated how the interplay between NK cells and HSCs are modified by insulin resistance in NAFLD. Fresh peripheral blood NK cells (clusters of differentiation [CD]56dim , CD16+ ) were collected from 22 healthy adults and 72 patients with NAFLD not currently taking any medications and without signs of metabolic syndrome...

Vinyl chloride (VC), a common industrial organochlorine and environmental pollutant, has been shown to directly cause hepatic angiosarcoma and toxicant-associated steatohepatitis at high exposure levels. However, the impact of lower concentrations of VC on the progression of underlying liver diseases (e.g., nonalcoholic fatty liver disease [NAFLD]) is unclear. Given the high prevalence of NAFLD in the United States (and worldwide) population, this is an important concern. Recent studies by our group with VC metabolites suggest a potential interaction between VC exposure and underlying liver disease to cause enhanced damage...
