Iron is an essential trace element whose absorption is usually tightly regulated in the duodenum. HFE-related hereditary hemochromatosis (HH) is characterized by abnormally low expression of the iron-regulatory hormone, hepcidin, which results in increased iron absorption. The liver is crucial for iron homeostasis as it is the main production site of hepcidin. The aim of this study was to explo...

Background: Iron overload can cause many complications and damage many organs as well as physiologic functions. Consumption of phetochemicals and flavonoids with iron chelating ability, instead of synthetic iron chelators, can be less harmful and more effective. The aim of this review is to investigate hydrophilic phytochelators in iron overload condition. Methods: In this review, the possible ...

Hepatic iron overload has been associated classically with the genetic disorder hereditary hemochromatosis. More recently, it has become apparent that mild-to-moderate degrees of elevated hepatic iron stores observed in other liver diseases also have clinical relevance. The goal was to use a mouse model of dietary hepatic iron overload and isobaric tag for relative and absolute quantitation pro...

Non-alcoholic fatty liver disease (NAFLD) includes a spectrum of clinical entities ranging from simple steatosis to non-alcoholic steatohepatitis (NASH) with possible evolution to cirrhosis and hepatocellular carcinoma. Iron is considered a putative element that interacts with oxygen radicals in inducing liver damage and fibrosis. The role of hepatic iron in the progression of NASH remains cont...

BACKGROUND AND OBJECTIVES Iron overload among hemodialysis patients was previously considered rare but is now an increasingly recognized clinical situation. We analyzed correlations between iron biomarkers and the liver iron concentration (LIC) measured by magnetic resonance imaging (MRI), and examined their diagnostic accuracy for iron overload. DESIGN, SETTING, PARTICIPANTS AND MEASUREMENTS...

Infection with Yersinia enterocolitica (YE) typically presents with mild gastroenteritis without systemic infection. However, systemic YE infection has been described in states of iron overload. We present the case of a patient with sepsis with hepatic abscesses due to YE infection. Workup revealed a past diagnosis of diabetes mellitus and hemochromatosis which had been untreated for the previo...

BACKGROUND/AIMS The pathogenesis of non-alcoholic steatohepatitis (NASH) is poorly understood. Hepatic iron and copper overload can directly cause lipid peroxidation and eventually hepatic damage. The aim of this study was to investigate the role of hepatic iron and copper accumulation in the development of NASH. METHODS Fifty-three patients with NASH were studied. All patients underwent live...

Background T2* measurement is widely used in the assessment of patients at risk for cardiac and hepatic iron overload (1,2). The conventional breath-hold, ECG-triggered, segmented, multi-echo gradient echo sequence (BH MGRE) used for myocardial T2* quantification (3) is very sensitive to respiratory motion and may not be feasible in patients who are unable to breath-hold. To overcome this limit...

Nonalcoholic fatty liver disease (NAFLD) is now the most common liver disease in the world. NAFLD can progress to nonalcoholic steatohepatitis (NASH), cirrhosis and eventually hepatocellular carcinoma. Acquired hepatic iron overload is seen in a number of patients with NAFLD; however, its significance in the pathology of NAFLD is still debated. Here, we investigated the role of dietary iron sup...

It is well known that hepatic siderosis and high serum iron levels occur in most PCT patients. The role of genetic hemochromatosis in the pathogenesis of iron overload in PCT has been hypothesized for many years but it is only recently that the genetic defect causing hemochromatosis has been identified. There are two known mutations in the hemochromatosis gene (HFE): cystein 282 tyrosine (Cys28...
