Endoplasmic reticulum (ER) stress is an important pathogenic mechanism for alcoholic (ALD) and nonalcoholic fatty liver disease (NAFLD). Iron overload is an important cofactor for liver injury in ALD and NAFLD, but its role in ER stress and associated stress signaling pathways is unclear. To investigate this, we developed a murine model of combined liver(More)
BACKGROUND Serum hepcidin concentration is potentially affected by inflammation and iron stores in chronic liver disease (CLD), but little is known about the relationship between hepcidin and the degree of hepatic fibrosis. We investigated the potential role of serum hepcidin as a biomarker of advanced liver disease. METHODS Serum hepcidin was measured in(More)
BACKGROUND & AIMS Adrenal insufficiency (AI) has been reported in patients with advanced liver disease. Diagnosing AI is problematic owing to controversies in using total serum cortisol as a measure of adrenal function. No published data exist on directly measured plasma free cortisol (PFC) in patients with liver disease. METHODS This prospective study(More)
Published data on adrenocortical function in septic shock have enrolled patients at various stages of critical illness and predominantly used plasma total cortisol, with minimal information on serial changes. Moreover, plasma free cortisol and tissue corticosteroid activity may not be strongly associated; however, few published data exist. The aim of this(More)
The HFE protein plays a crucial role in the control of cellular iron homeostasis. Steatosis is commonly observed in HFE-related iron-overload disorders, and current evidence suggests a causal link between iron and steatosis. Here, we investigated the potential contribution of HFE mutations to hepatic lipid metabolism and its role in the pathogenesis of(More)
OBJECTIVE To investigate the agreement between two methods of measurement of plasma free cortisol in acutely ill patients; an indirect method using the Coolens equation, and direct measurement using high-performance liquid chromatography-tandem mass spectrometry, which is the gold standard. DESIGN, PARTICIPANTS AND SETTING Prospective observational study(More)
BACKGROUND & AIMS Hyperferritinemia is a common abnormality. This study determined the prevalence of hepatic iron overload in subjects of northern European origin with hyperferritinemia. METHODS Fifty-two consecutive subjects referred for evaluation of suspected iron overload (serum ferritin level >350 microg/L) were divided into 3 groups: group 1,(More)
AIM To assess the efficacy and safety of mycophenolate mofetil (MMF) prospectively in inflammatory bowel disease (IBD) patients intolerant or refractory to conventional medical therapy. METHODS Crohn's disease (CD) or ulcerative colitis/IBD unclassified (UC/IBDU) patients intolerant or refractory to conventional medical therapy received MMF (500-2000 mg(More)
BACKGROUND Combined iron overload and alcohol may promote synergistic chronic liver injury and toxicity. The role of specific dietary fats in influencing the development of co-toxic alcoholic liver disease needs further evaluation and is investigated in this study. METHODS Wild-type (WT) and the iron-loaded Hfe-null (Hfe(-/-) ) mice were fed chow (CC), a(More)
