AIM: To characterize the effect of hepatic steatosis (HS) on the progression of chronic hepatitis B. METHODS: A total of 162 chronic hepatitis B (CHB) patients confirmed by liver biopsy were involved in this study. All subjects were prospectively followed-up for 5 years in real-life clinical practice. Fibrosis stage was determined using aspartate aminotransferase-to-platelet ratio index (APRI). The end-point was cirrhosis, liver cancer or death. The effects of steatosis on the biological behavior of hepatocellular carcinoma cells were investigated using oleic acid-induced lipid accumulation in HepG2, HLE, PLC, and SMMC-7721 cells...

Glucocorticoids influence a wide range of metabolic processes in the human body and excessive glucocorticoid exposure is known to contribute to the development of metabolic disease. We evaluated the utility of the novel glucocorticoid receptor (GR) antagonist CORT125281 for its potential to overcome adiposity, glucose intolerance and dyslipidaemia, and compared this head-to-head with classic GR antagonist RU486 (mifepristone). We show that, while RU486 displays cross-reactivity to the progesterone and androgen receptor, CORT125281 selectively inhibits GR transcriptional activity...

Context: Bile acids (BA) are signalling molecules controlling energy homeostasis which can be both toxic and protective for the liver. BA alterations have been reported in obesity, insulin resistance (IR) and non-alcoholic steatohepatitis (NASH). However whether BA alterations contribute to NASH independently of the metabolic status is unclear. Objective: To assess BA alterations associated with NASH independently of BMI and IR. Design & Setting: Patients visiting the obesity clinic of the Antwerp University Hospital (a tertiary referral facility) were recruited from 2006 to 2014...

Context: Obesity is associated with hypoadiponectemia, dyslipidemia and increased risk of coronary vascular disease (CVD). Mechanisms linking these conditions remain to be fully understood. Cholesterol efflux capacity (CEC) is a crucial functional property of high-density lipoprotein (HDL) that strongly predicts CVD incidence. Objective: To investigate whether age, fat distribution, and other obesity related factors affect CEC in juvenile and adult overweight/obese participants of the STYJOBS/EDECTA cohort (NCT00482924)...

MC analysis of biological tissue is considered to be very difficult due to the lack of validated methods. This is the primary limiting factor for monitoring potential risks in both the flesh of aquatic organisms and the aquatic ecosystem. In this study, an effective method to determine free MCs (MC-LR and MC-RR) in the muscle and liver tissues of freshwater cultured fish was developed using solid-phase extraction (SPE) and liquid chromatography-tandem mass spectrometry (LC/MS-MS). The extraction solvent, time of extraction, eluent and purification of the extract were optimized...

This cross-sectional study was conducted on 15 infants and toddlers with chronic liver disease (CLD) to validate arm anthropometry as an accurate measure of body composition (BC) compared to dual-energy X-ray absorptiometry (DXA) and to predict growth from BC.The z-score means of the anthropometric indicators were < -2SD, except for body fat index and subscapular skinfold which were between -2 and +2 SD. Fat mass was predicted by arm adiposity indicators and fat-free mass by arm muscle area. Bone mineral content explained 87% of variation in length...

OBJECTIVES: Cerebrotendinous xanthomatosis (CTX) is caused by defects in sterol 27-hydroxylase (CYP27A1, encoded by CYP27A1), a key enzyme in the bile acid synthesis pathway. CTX usually presents as neurologic disease in adults or older children. The very rare reports of CTX manifest as neonatal cholestasis assess the cholestasis as transient, with patient survival. Our experience differs. METHODS: Homozygous or compound heterozygous CYP27A1 mutations were detected in 8 neonatal cholestasis patients by whole exome sequencing, panel sequencing, or Sanger sequencing...

We report a case of intrapulmonary ectopic liver associated with Scimitar syndrome. A two month old male child who presented with features of congestive cardiac failure underwent extensive cardiac and radiological investigations and was diagnosed with Scimitar syndrome. He was also found to have a mass in the lower lobe of the right lung, the possibilities being either a pulmonary sequestration or a diaphragmatic hernia. As his dyspnea progressively worsened, a right lower lobectomy was performed at the age of two years...

LC-MS and immunoassay can detect protein biomarkers. Immunoassays are more commonly used but can potentially be outperformed by LC-MS. These techniques have limitations including the necessity to generate separate calibration curves for each biomarker. We present a rapid mass spectrometry-based assay utilising a universal calibration curve. For the first time we analyse clinical samples using the HeavyPeptide IGNIS kit which establishes a 6-point calibration curve and determines the biomarker concentration in a single LC-MS acquisition...

BACKGROUND: Brain gray (GM) and white matter (WM) volumes are related to weight changes. The impact of structural variations in GM and WM on the variance in resting energy expenditure (REE) and the REE on fat free mass (FFM) association is unknown. The aim of this study was to address this in healthy Caucasian subjects. METHODS: Cross-sectional data analysis of 493 healthy Caucasian subjects (age range 6 to 80 years; three age groups) with comprehensive information on FFM, organ and tissue masses and detailed brain composition as assessed by whole body magnetic resonance imaging (MRI) and REE (assessed by indirect calorimetry)...

Hepatic myelolipoma is a rare entity with only 17 cases described in the literature. A 73mm right liver mass was fortuitously discovered in a 55-year-old man. The biopsy showed normal hepatic tissue adjacent to a normal medular like hematopoïetic tissue, showing trilieage hematopoieses, including myeloid cells, erythroid cells and megakaryocytic cells. The diagnosis of hepatic myelolipoma was proposed. This benign tumor was initially described in adrenal gland, which is the most common topography. No malignancy or bleeding complication has been described in its hepatical location...

Selaginella tamariscina (Beauv.) has been used for traditional herbal medicine for treatment of cancer, hepatitis, and diabetes in the Orient. Numerous bioactive compounds including alkaloids, flavonoids, lignans, and selaginellins have been identified in this medicinal plant. Among them, selaginellins having a quinone methide unit and an alkylphenol moiety have been known to possess anticancer, antidiabetic, and neuroprotective activity. Although there have been studies on the biological activities of selaginellins, their modulatory potential of cytochrome P450 (P450) and uridine 5'-diphosphoglucuronosyltransferase (UGT) activities have not been previously evaluated...

Anorexia nervosa (AN) has the highest mortality rate of all psychiatric illnesses due to the widespread organ dysfunction caused by the underlying severe malnutrition. Starvation causes hepatocyte injury and death leading to a rise in aminotransferases. Malnutrition-induced hepatitis is common among individuals with AN especially as body mass index decreases. Acute liver failure associated with coagulopathy and encephalopathy can rarely occur. Liver enzymes may also less commonly increase as part of the refeeding process due to hepatic steatosis and can be distinguished from starvation hepatitis by the finding of a fatty liver on ultrasonography...

Carney triad is a synchronous or metachronous association of gastric gastrointestinal stromal tumors (GIST), pulmonary chondroma and extra-adrenal paraganglioma. The majority of patients have only one or two components of the triad, all three tumors being found in only about 2% of the patients at the time of the first diagnosis. The most common combination is gastric and pulmonary tumors. We report a case of Carney triad which was diagnosed at Masaryk Memorial Cancer Institute. A 57-year-old female patient with a history of gastric resection for leiomyosarcoma at the age of 14 and with an unclear pulmonary lesion evident on chest X-ray since as early as 2003...

Rhein, a glucoside chemical compound found in a traditional Chinese medicine derived from the roots of rhubarb, induces cell apoptosis and is considered to have high potential as an antitumor drug. Several previous studies showed that rhein can inhibit cell proliferation and trigger mitochondria-related or endoplasmic reticulum (ER) stress-dependent apoptotic processes. However, the side effects of rhein on pre- and post-implantation embryonic development remain unclear. Here, we show that rhein has cytotoxic effects on blastocyst-stage mouse embryos and induces oxidative stress and immunotoxicity in mouse fetuses...

REVIEW
Yves Ingenbleek
Protein-depleted states generate allosteric inhibition of liver cystathionine β-synthase (CBS), which governs the first enzymatic step of the transsulfuration cascade, resulting in upstream accretion of homocysteine (Hcy) in body fluids. A similar Hcy increase may arise from normal hepatocytes undergoing experimentally-induced impairment of betaine-homocysteine methyltransferase (BHTM) activity or from components of lean body mass (LBM) submitted to any inflammatory disorder. LBM comprises a composite agglomeration of extrarenal tissues characterized by naturally occurring BHTM inactivity...
