    Division of Gene Therapy, Research Center for Medical Sciences, The Jikei University School of Medicine, Tokyo, Japan; Department of Pediatrics, The Jikei University School of Medicine, Tokyo, Japan. Electronic address:
    Formation of antibodies against a therapeutic enzyme is an important complication during enzyme replacement therapy (ERT) for lysosomal storage diseases. Fabry disease (FD) is caused by a deficiency of alpha-galactosidase (GLA), which results in the accumulation of globotriaosylceramide (GL-3). We have shown immune tolerance induction (ITI) during ERT in FD model mice by using an anti-B lymphocyte stimulator (anti-BlyS) antibody (belimumab). Read More

    Inherited and Uncommon Causes of Stroke.
    Continuum (Minneap Minn) 2017 Feb;23(1, Cerebrovascular Disease):211-237
    Purpose Of Review: This article is a practical guide to identifying uncommon causes of stroke and offers guidance for evaluation and management, even when large controlled trials are lacking in these rarer forms of stroke.

    Recent Findings: Fabry disease causes early-onset stroke, particularly of the vertebrobasilar system; enzyme replacement therapy should be considered in affected patients. Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL), often misdiagnosed as multiple sclerosis, causes migraines, early-onset lacunar strokes, and dementia.

    When arthralgia is not arthritis.
    Eur J Rheumatol 2016 Dec 5;3(4):182-184. Epub 2016 Apr 5.
    Department of Neurology, Division, of Neurometabolism, Foundation for Study of Neurometabolic Diseases, (FESEN), Buenos Aires, Argentina.
    The presence of distal extremity pain in children and adolescents usually triggers the search of rheumatologic diseases without considering non-rheumatologic causes of joint pain. Approaching distal extremity pain with a complete differential diagnosis, including non-rheumatologic entities, may hasten diagnosis, thus decreasing cost and aiding in earlier initiation of appropriate therapy. To present a case of a patient who after years of work up of arthralgia, which was actually attributed to rheumatologic causes, had an inherited metabolic disease. Read More

    Département de dermatologie, Hôpital Hôtel-Dieu de France, Faculté de médecine, Université Saint-Joseph, Beyrouth, Liban.
    Fabry disease, also known as Anderson-Fabry disease or angiokeratoma corporis diffusum universale, is an X-linked recessive form of sphingolipidosis caused by total or partial deficiency of the lysosomal hydrolase, alpha-galactosidase A. From the youngest age, it results in a gradual ubiquitous build-up of glycosphingolipids that are not degraded by the missing enzyme. Cutaneous, neurological, nephrologic, cardiac, gastrointestinal, ophthalmological, respiratory, cochleovestibular and haematological involvement are responsible for increased mortality and significant impairment of quality of life in subjects affected by the disease.

    Impact of lysosomal storage disorders on biology of mesenchymal stem cells: Evidences from in vitro silencing of glucocerebrosidase (GBA) and alpha-galactosidase A (GLA) enzymes.
    J Cell Physiol 2017 Jan 18. Epub 2017 Jan 18.
    Department of Experimental Medicine, Biotechnology and Molecular Biology Section, Second University of Naples, Naples, Italy.
    Lysosomal storage disorders (LDS) comprise a group of rare multisystemic diseases resulting from inherited gene mutations that impair lysosomal homeostasis. The most common LSDs, Gaucher disease (GD), and Fabry disease (FD) are caused by deficiencies in the lysosomal glucocerebrosidase (GBA) and alpha-galactosidase A (GLA) enzymes, respectively. Given the systemic nature of enzyme deficiency, we hypothesized that the stem cell compartment of GD and FD patients might be also affected. Read More

    [Glomerular lipidosis].
    G Ital Nefrol 2016 Malattie Metaboliche e Rene;33(S68)
    Lipidoses occur for an abnormal storage parenchymal deposition of lipids and products of their metabolism in large amounts or sometimes, involving only some particular tissue structures. The lipid storage is usually due to an inborn error causing an enzyme absence /deficiency in the primary lipidoses and to a complex metabolism alterations in the secondary forms. However, histologically all lipid depositions look very similar, and immunohistochemical investigation, clinical pictures knowledge and genetic tests need to make a correct diagnosis. Read More

    Imbalanced Production of Reactive Oxygen Species and Mitochondrial Antioxidant-SOD2 in Fabry Disease-specific Human Induced Pluripotent Stem Cell-differentiated Vascular Endothelial Cells.
    Cell Transplant 2016 12 6. Epub 2016 Dec 6.
    Departments of Pediatrics and Laboratory Medicine, Kaohsiung Medical University Hospital, Kaohsiung Medical University, Kaohsiung, Taiwan
    Fabry disease (FD) is an X-linked inherited lysosomal storage disease caused by α-galactosidase A (GLA) deficiency. Progressive intracellular accumulation of globotriaosylceramide (Gb3) is considered to be pathogenically responsible for the phenotype variability of FD that causes cardiovascular dysfunction; however, molecular mechanisms underlying the impairment of FD-associated cardiovascular tissues remain unclear. In this study, we reprogrammed human induced pluripotent stem cells (hiPSC) from peripheral blood cells of patients with FD (FD-iPSCs); subsequently differentiated them into vascular endothelial-like cells (FD-ECs) expressing CD31, VE-cadherin, and vWF; and investigated their ability to form vascular tube-like structures.

    Importance: Erythromelalgia is a clinical diagnosis based on intermittent warmth, erythema, and pain in the distal extremities. One problem facing physicians is how to objectively test for this disease. Given that other painful conditions of the distal extremities (ie, neuropathy related to human immunodeficiency virus, diabetes, or Fabry disease) can be evaluated with a skin biopsy to visualize pathologically decreased densities of the small nerve fibers that innervate the epidermis, one hypothesis is that erythromelalgia could similarly be associated with a loss of epidermal nerve fiber density (ENFD).

    Fabry disease is caused by mutations in the GLA gene and is characterized by a large genotypic and phenotypic spectrum. Missense mutations pose a special problem for graduating diagnosis and choosing a cost-effective therapy. Some mutants retain enzymatic activity, but are less stable than the wild type protein.
