    Iron participates in oxygen transport, energetic, metabolic, and immunologic processes. There are 2 main causes of iron overload: hereditary hemochromatosis which is a primary cause, is a metabolic disorder caused by mutations of genes that control iron metabolism and secondary hemochromatosis caused by multitransfusions, chronic hemolysis, and intake of iron rich food. The most common type of hereditary hemochromatosis is caused by HFE gene mutation. Read More

    IUBMB Life 2017 Apr 6. Epub 2017 Apr 6.
    Lady Davis Institute for Medical Research and Department of Medicine, McGill University, Montreal, Quebec, Canada.
    Iron is an essential nutrient that is potentially toxic due to its redox reactivity. Insufficient iron supply to erythroid cells, the major iron consumers in the body, leads to various forms of anemia. On the other hand, iron overload (hemochromatosis) is associated with tissue damage and diseases of liver, pancreas, and heart. Read More

    The role of iron in the pathogenesis of atherosclerosis.
    Physiol Res 2017 Apr;66(Supplementum 1):S55-S67
    Second Department of Internal Medicine, Third Faculty of Medicine, Charles University and University Hospital Královské Vinohrady, Prague, Czech Republic.
    Ferritin and increased iron stores first appeared on the list of cardiovascular risk factors more than 30 years ago and their causal role in the pathogenesis of atherosclerosis has been heavily discussed since the early 1990s. It seems that besides traditional factors such as hyperlipoproteinemia, hypertension, diabetes mellitus, obesity, physical inactivity, smoking and family history, high iron stores represent an additional parameter that could modify individual cardiovascular risk. The role of iron in the pathogenesis of atherosclerosis was originally primarily associated with its ability to catalyze the formation of highly reactive free oxygen radicals and the oxidation of atherogenic lipoproteins.

    Mice lacking liver-specific β-catenin develop steatohepatitis and fibrosis after iron overload.
    J Hepatol 2017 Mar 21. Epub 2017 Mar 21.
    Department of Pathology (Division of Experimental Pathology), University of California at Los Angeles, Los Angeles, CA; Pittsburgh Liver Research Center, University of California at Los Angeles, Los Angeles, CA; Department of Medicine (Division of Gastroenterology, Hepatology and Nutrition), University of California at Los Angeles, Los Angeles, CA. Electronic address:
    Background & Aims: Iron overload disorders such as hereditary hemochromatosis and iron-loading anemias are a common cause of morbidity from liver diseases and increase risk of hepatic fibrosis and hepatocellular carcinoma (HCC). Once iron-induced damage occurs, treatment options are limited partly because of the lack of animal models recapitulating human disease, which do not exhibit relevant sequelae after chronic iron overload.

    Methods: Since liver-specific β-catenin knockout mice (KO) are susceptible to injury, fibrosis and tumorigenesis following chemical carcinogen exposure, iron-overload diet was administered to KO and littermate control (CON) mice for various times. Read More

    Identification of New BMP6 Pro-Peptide Mutations in Patients with Iron Overload.
    Am J Hematol 2017 Mar 23. Epub 2017 Mar 23.
    Department of Medicine, Section of Internal Medicine, University of Verona, Verona, Italy.
    Hereditary Hemochromatosis (HH) is a genetically heterogeneous disorder caused by mutations in at least 5 different genes (HFE, HJV, TFR2, SLC40A1, HAMP) involved in the production or activity of the liver hormone hepcidin, a key regulator of systemic iron homeostasis. Nevertheless, patients with an HH-like phenotype that remains completely/partially unexplained despite extensive sequencing of known genes are not infrequently seen at referral centers, suggesting a role of still unknown genetic factors. A compelling candidate is Bone Morphogenetic Protein 6 (BMP6), which acts as a major activator of the BMP-SMAD signaling pathway, ultimately leading to the upregulation of hepcidin gene transcription.

    Diabetes in HFE Hemochromatosis.
    J Diabetes Res 2017 26;2017:9826930. Epub 2017 Feb 26.
    Southern Iron Disorders Center, Birmingham, AL 35209, USA; Department of Microbiology, University of Alabama at Birmingham, Birmingham, AL 35294, USA.
    Diabetes in whites of European descent with hemochromatosis was first attributed to pancreatic siderosis. Later observations revealed that the pathogenesis of diabetes in HFE hemochromatosis is multifactorial and its clinical manifestations are heterogeneous. Increased type 2 diabetes risk in HFE hemochromatosis is associated with one or more factors, including abnormal iron homeostasis and iron overload, decreased insulin secretion, cirrhosis, diabetes in first-degree relatives, increased body mass index, insulin resistance, and metabolic syndrome.

    The Regulation of Iron Absorption and Homeostasis.
    Clin Biochem Rev 2016 May;37(2):51-62
    QIMR Berghofer Medical Research Institute, Brisbane, Queensland, 4006 Australia.
    Iron is an essential element in biology, required for numerous cellular processes. Either too much or too little iron can be detrimental, and organisms have developed mechanisms for balancing iron within safe limits. In mammals there are no controlled mechanisms for the excretion of excess iron, hence body iron homeostasis is regulated at the sites of absorption, utilisation and recycling. Read More

    HFE mutations and iron in hemodialysis patients.
    Hemodial Int 2017 Mar 15. Epub 2017 Mar 15.
    Department of Pathophysiology and Transplantation, Internal Medicine and Metabolic Diseases, Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico, Università degli Studi di Milano, Milano, Italy.
    Introduction: in chronic hemodialysis patients, a disruption in iron metabolism ranging from absolute to functional deficiency, with compartmentalization of this metal into macrophages, is often observed. Chronic inflammation indeed often causes an upregulation of the iron hormone hepcidin, thereby reducing iron absorption and availability to the erythron.

    Methods: we systematically reviewed the literature on the role of genetic risk factors on iron metabolism in hemodialysis. Read More

It also summarises the venesection procedure itself and the considerations for setting up a venesection service in a doctor's surgery. Read More

    DIAGNOSIS OF ENDOCRINE DISEASE: Expanding the cause of hypopituitarism.
    Eur J Endocrinol 2017 Jun 3;176(6):R269-R282. Epub 2017 Mar 3.
    School of MedicineUniversity of Belgrade, Belgrade, Serbia
    Hypopituitarism is defined as one or more pituitary hormone deficits due to a lesion in the hypothalamic-pituitary region. By far, the most common cause of hypopituitarism associated with a sellar mass is a pituitary adenoma. A high index of suspicion is required for diagnosing hypopituitarism in several other conditions such as other massess in the sellar and parasellar region, brain damage caused by radiation and by traumatic brain injury, vascular lesions, infiltrative/immunological/inflammatory diseases (lymphocytic hypophysitis, sarcoidosis and hemochromatosis), infectious diseases and genetic disorders.

    Serum ferritin concentration predicts hepatic fibrosis better than hepatic iron concentration in human HFE-Haemochromatosis.
    Liver Int 2017 Feb 23. Epub 2017 Feb 23.
    Hepatic Fibrosis Group, QIMR Berghofer Medical Research Institute, Brisbane, Queensland, Australia.
    Background & Aims: Ferritin is purported to have proinflammatory and profibrogenic effects on hepatic stellate cells. Thus, rather than acting as a passive indicator of hepatic iron concentration (HIC) in haemochromatosis, ferritin may directly influence fibrosis. This study evaluated whether serum ferritin is a better predictor of hepatic fibrosis compared to variables previously associated with increased fibrosis risk in haemochromatosis. Read More

    Whole genome sequencing of one complex pedigree illustrates challenges with genomic medicine.
    BMC Med Genomics 2017 Feb 23;10(1):10. Epub 2017 Feb 23.
    Stanley Institute for Cognitive Genomics, One Bungtown Road, Cold Spring Harbor Laboratory, Cold Spring Harbor, NY, USA.
    Background: Human Phenotype Ontology (HPO) has risen as a useful tool for precision medicine by providing a standardized vocabulary of phenotypic abnormalities to describe presentations of human pathologies; however, there have been relatively few reports combining whole genome sequencing (WGS) and HPO, especially in the context of structural variants.

    Methods: We illustrate an integrative analysis of WGS and HPO using an extended pedigree, which involves Prader-Willi Syndrome (PWS), hereditary hemochromatosis (HH), and dysautonomia-like symptoms. A comprehensive WGS pipeline was used to ensure reliable detection of genomic variants. Read More

    Eur J Med Chem 2017 Mar 11;129:110-123. Epub 2017 Feb 11.
    Department of Pharmacology-Physiology, Université de Sherbrooke, 3001 12(e) Avenue Nord, Sherbrooke, Québec, J1H 5N4, Canada; Institut de Pharmacologie de Sherbrooke, Université de Sherbrooke, 3001 12(e) Avenue Nord, Sherbrooke, Québec, J1H 5N4, Canada. Electronic address:
    Matriptase-2, a type II transmembrane serine protease (TTSP), is expressed in the liver and regulates iron homeostasis via the cleavage of hemojuvelin. Matriptase-2 emerges as an attractive target for the treatment of conditions associated with iron overload, such as hemochromatosis or beta-thalassemia. Starting from the crystal structure of its closest homolog matriptase, we constructed a homology model of matriptase-2 in order to further optimize the selectivity of serine trap peptidomimetic inhibitors for matriptase-2 vs matriptase.

    Center for Iron Disorders, Department of Medicine, David Geffen School of Medicine, University of California Los Angeles, Los Angeles, CA
    Iron is required for many biological processes but is also toxic in excess; thus, body iron balance is maintained through sophisticated regulatory mechanisms. The lack of a regulated iron excretory mechanism means that body iron balance is controlled at the level of absorption from the diet. Iron absorption is regulated by the hepatic peptide hormone hepcidin. Read More

    Relevance of C5b9 immunostaining in the diagnosis of neonatal hemochromatosis.
    Pediatr Res 2017 Mar 1. Epub 2017 Mar 1.
    Department of pathology, Hôpital Femme-Mère-Enfant, CHU de Lyon, France.
    Background: Neonatal hemochromatosis caused by a gestational alloimmune mechanism or gestational alloimmune liver disease (GALD) is a rare perinatal disorder characterized by intra- and extrahepatic iron overload. It is believed to result from complement-mediated liver injury, in which the classical complement pathway is activated by maternal antibody/fetal antigen complexes, leading to hepatocyte lysis by the membrane attack complex C5b9. According to some authors, C5b9 expression in more than 75% of liver parenchyma is specific for GALD. Read More
