    The role of T2*-weighted gradient echo in the diagnosis of tumefactive intrahepatic extramedullary hematopoiesis in myelodysplastic syndrome and diffuse hepatic iron overload: a case report and review of the literature.
    J Med Case Rep 2018 Jan 15;12(1). Epub 2018 Jan 15.
    Department of Diagnostic Radiology, University of Iowa Hospitals and Clinics, 200 Hawkins Dr, Iowa City, IA, 52242, USA.
    Background: Extramedullary hematopoiesis is the proliferation of hematopoietic cells outside bone marrow secondary to marrow hematopoiesis failure. Extramedullary hematopoiesis rarely presents as a mass-forming hepatic lesion; in this case, imaging-based differentiation from primary and metastatic hepatic neoplasms is difficult, often leading to biopsy for definitive diagnosis. We report a case of tumefactive hepatic extramedullary hematopoiesis in the setting of myelodysplastic syndrome with concurrent hepatic iron overload, and the role of T2*-weighted gradient-echo magnetic resonance imaging in differentiating extramedullary hematopoiesis from primary and metastatic hepatic lesions.

    Advanced iron-overload cardiomyopathy in a genetic murine model is rescued by resveratrol therapy.
    Biosci Rep 2018 Feb 10;38(1). Epub 2018 Jan 10.
    Division of Cardiology, Department of Medicine, University of Alberta, Edmonton, Canada
    Iron-overload cardiomyopathy is prevalent on a worldwide basis and is a major comorbidity in patients with genetic hemochromatosis and secondary iron overload. Therapies are limited in part due to lack of a valid preclinical model, which recapitulates advanced iron-overload cardiomyopathy. Male hemojuvelin (HJV) knockout (HJVKO) mice, which lack HJV, a bone morphogenetic co-receptor protein required for hepcidin expression and systemic iron homeostasis, were fed a high-iron diet starting at 4 weeks of age for a duration of 1 year.

    The interaction of iron and the genome: For better and for worse.
    Mutat Res 2017 Oct 14;774:25-32. Epub 2017 Sep 14.
    SFR Biosit UMS CNRS 3480/US INSERM 018, Rennes, France; Institut NuMeCan, Inserm U 1241, Université de Rennes 1, Rennes, France.
    Iron, as an essential nutrient, and the DNA, as the carrier of genetic information which is physically compacted into chromosomes, are both needed for normal life and well-being. Therefore, it is not surprising that close interactions exist between iron and the genome. On the one hand, iron, especially when present in excess, may alter genome stability through oxidative stress, and may favor cell cycle abnormalities and the development of malignant diseases.

    Genetic hemochromatosis: Pathophysiology, diagnostic and therapeutic management.
    Presse Med 2017 Dec 20;46(12 Pt 2):e288-e295. Epub 2017 Nov 20.
    Inserm-UMR 991, 2, rue Henri-Le-Guilloux, 35033 Rennes, France.
    The term hemochromatosis (HC) corresponds to several diseases characterized by systemic iron overload of genetic origin and affecting both the quality of life and life expectancy. Major improvement in the knowledge of iron metabolism permits to divide these diseases into two main pathophysiological categories. For most HC forms (types 1, 2, 3 and 4B HC) iron overload is related to cellular hepcidin deprivation which causes an increase of plasma iron concentration and the appearance of plasma non-transferrin bound iron.

    Iron induced RNA-oxidation in the general population and in mouse tissue.
    Free Radic Biol Med 2018 Feb 20;115:127-135. Epub 2017 Nov 20.
    Department of Clinical Pharmacology, Bispebjerg and Frederiksberg Hospital, Copenhagen, Denmark; Faculty of Health and Medical Sciences, University of Copenhagen, Copenhagen, Denmark.
    Iron promotes formation of hydroxyl radicals by the Fenton reaction, subsequently leading to potential oxidatively generated damage of nucleic acids. Oxidatively generated damage to RNA, measured as 8-oxo-7,8-dihydroguanosine (8-oxoGuo) in urine, is increased in patients with genetic iron overload, which have led us to test the hypothesis that high iron status, assessed by iron biomarkers and genetic disposition, increases urinary excretion of 8-oxoGuo. In a general Danish population study we used a Mendelian randomization design with HFE genotypes as a proxy for iron status and supplemented with ex vivo experiments in mice muscle tissue exposed to iron(II) sulfate to attempt to clarify this hypothesis.

    Characterization of three novel pathogenic SLC40A1 mutations and genotype/phenotype correlations in 7 Italian families with type 4 hereditary hemochromatosis.
    Biochim Biophys Acta 2018 Feb 14;1864(2):464-470. Epub 2017 Nov 14.
    Department of Biosciences and Territory, University of Molise, Pesche, Italy. Electronic address:
    Mutations of SLC40A1 encoding ferroportin (Fpn), the unique cellular iron exporter, severely affect iron homeostasis causing type 4 hereditary hemochromatosis, an autosomal dominant iron overload condition with variable phenotypic manifestations. This disease can be classified as type 4A, better known as "ferroportin disease", which is due to "loss of function" mutations that lead to decreased iron export from cells, or as type 4B hemochromatosis, which is caused by "gain of function" mutations, conferring partial or complete resistance to hepcidin-mediated Fpn degradation. In this work, we discuss clinical and molecular findings on a group of patients in whom a SLC40A1 single copy missense variant was identified. Read More

    Iatrogenic iron overload and its potential consequences in patients on hemodialysis.
    Presse Med 2017 Dec 16;46(12 Pt 2):e312-e328. Epub 2017 Nov 16.
    University of California, Division of Nephrology and Hypertension, Irvine, USA.
    Iron overload was considered rare in hemodialysis patients until recently, but its clinical frequency is now increasingly recognized. The liver is the main site of iron storage and the liver iron concentration (LIC) is closely correlated with total iron stores in patients with secondary hemosiderosis and genetic hemochromatosis. Magnetic resonance imaging (MRI) is now the gold standard method for estimating and monitoring LIC. Read More

    Diagnosis of hyperferritinemia in routine clinical practice.
    Presse Med 2017 Dec 20;46(12 Pt 2):e329-e338. Epub 2017 Nov 20.
    CHU de Dijon, hôpital du Bocage, 2, boulevard du Maréchal-de-Lattre-de-Tassigny, BP 77908, 21079 Dijon cedex, France.
    The discovery of hyperferritinemia is often fortuitous, revealed in results from a laboratory screening or follow-up test. The aim of the diagnostic procedure is therefore to identify its cause and to identify or rule out hepatic iron overload, in a three-stage process. In the first step, clinical findings and several simple laboratory tests are sufficient to detect four of the most frequent causes of high ferritin concentrations: alcoholism, inflammatory syndrome, cytolysis, and metabolic syndrome.

    Iron and infection.
    Int J Hematol 2018 Jan 16;107(1):7-15. Epub 2017 Nov 16.
    CHS 52-243, Departments of Medicine and Pathology, David Geffen School of Medicine, University of California, 10833 Le Conte Ave., Los Angeles, CA, 90095, USA.
    Iron is an essential trace metal for nearly all infectious microorganisms, and host defense mechanisms target this dependence to deprive microbes of iron. This review highlights mechanisms that are activated during infections to restrict iron on mucosal surfaces, in plasma and extracellular fluid, and within macrophages. Iron overload disorders, such as hereditary hemochromatosis or β-thalassemia, interfere with iron-restrictive host responses, and thereby cause increased susceptibility to infections with microbes that can exploit this vulnerability.

    Although iron is vital, its free form is likely to be involved in oxidation-reduction reactions, leading to the formation of free radicals and oxidative stress. Living organisms have developed protein systems to transport free iron through the cell membranes and biological fluids and store it in a non-toxic and readily mobilizable form to avoid iron toxicity. Hepcidin plays a crucial role in maintaining iron homeostasis. Read More

    Iron Metabolism Laboratory, QIMR Berghofer Medical Research Institute, Herston, Queensland, Australia; and Schools of.
    Iron is an essential trace element, but it is also toxic in excess, and thus mammals have developed elegant mechanisms for keeping both cellular and whole-body iron concentrations within the optimal physiologic range. In the diet, iron is either sequestered within heme or in various nonheme forms. Although the absorption of heme iron is poorly understood, nonheme iron is transported across the apical membrane of the intestinal enterocyte by divalent metal-ion transporter 1 (DMT1) and is exported into the circulation via ferroportin 1 (FPN1).

    Objectives: Intrahepatic (ICC) and extrahepatic (ECC) cholangiocarcinomas are rare tumors that arise from the epithelial cells of the bile ducts, and the etiology of both cancer types is poorly understood. Thus, we utilized the Surveillance, Epidemiology, and End Results (SEER)-Medicare resource to examine risk factors and novel preexisting medical conditions that may be associated with these cancer types.

    Methods: Between 2000 and 2011, 2,092 ICC and 2,981 ECC cases and 323,615 controls were identified using the SEER-Medicare database. Read More

    Increased Plasma Ferritin Concentration and Low-Grade Inflammation-A Mendelian Randomization Study.
    Clin Chem 2017 Oct 16. Epub 2017 Oct 16.
    Faculty of Health and Medical Sciences, University of Copenhagen, Copenhagen, Denmark;
    Background: It is unknown why increased plasma ferritin concentration predicts all-cause mortality. As low-grade inflammation and increased plasma ferritin concentration are associated with all-cause mortality, we hypothesized that increased plasma ferritin concentration is genetically associated with low-grade inflammation.

    Methods: We investigated whether increased plasma ferritin concentration is associated with low-grade inflammation [i. Read More

    A Patient with Nafcillin-Associated Drug-Induced Liver Failure.
    Case Rep Gastroenterol 2017 Sep-Dec;11(3):564-568. Epub 2017 Sep 26.

    Nafcillin-induced acute liver injury is a rare and potentially fatal complication that has been known since the 1960s but inadequately studied. At this time, the only proven treatment is early discontinuation of the drug. Because of the high prevalence of nafcillin class antibiotic use in the United States, it is important for clinicians to have a high clinical suspicion for this diagnosis. Read More

    Introduction: The aim of this study is to describe a case of a melanotic macule found in conjunction with a giant cell fibroma (GCF). For oral pigmented lesions without an identifiable etiologic factor, critical factors in determining the differential diagnosis are clinical history, symmetry, and uniformity of the lesions. Potential differential diagnosis includes racial pigmentation, endocrine disturbance, Peutz-Jeghers syndrome, trauma, hemochromatosis, oral malignant melanoma, or idiopathic etiology and melanotic macules.
