Vibratory Urticaria
Vibratory urticaria Description Vibratory urticaria is a condition in which exposing the skin to vibration, repetitive stretching, or friction results in allergy symptoms such as hives (urticaria), swelling ( angioedema), redness (erythema), and itching (pruritus) in the affected area. The reaction can be brought on by towel drying, hand clapping, running, a bumpy ride in a vehicle, or other repetitive stimulation. Headaches, fatigue, faintness, blurry vision, a metallic taste in the mouth, facial flushing, and more widespread swelling (especially of the face) can also occur during these episodes, especially if the stimulation is extreme or prolonged. The reaction occurs within a few minutes of the stimulation and generally lasts up to an hour. Affected individuals can have several episodes per day. Frequency Vibratory urticaria is a rare disorder; its prevalence is unknown. It belongs to a class of disorders called physical urticarias in which allergy symptoms are brought on by direct exposure to factors such as pressure, heat, cold, or sunlight. Physical urticarias have been estimated to occur in up to 5 per 1,000 people. Causes Vibratory urticaria can be caused by a mutation in the ADGRE2 gene. This gene provides instructions for making a protein found in several types of immune system cells, including mast cells. Mast cells, which are found in many body tissues including the skin, are important for the normal protective functions of the immune system. They also play a role in allergic reactions, which occur when the immune system overreacts to stimuli that are not harmful. The specific role of the ADGRE2 protein in mast cells is not well understood. -

10 Chronic Urticaria As an Autoimmune Disease
10 Chronic Urticaria as an Autoimmune Disease Michihiro Hide, Malcolm W. Greaves Introduction Urticaria is conventionally classified as acute, intermittent and chronic (Grea- ves 2000a). Acute urticaria which frequently involves an IgE-mediated im- munological mechanism, is common, its causes often recognised by the patient, and will not be considered further. Intermittent urticaria – frequent bouts of unexplained urticaria at intervals of weeks or months – will be dis- cussed here on the same basis as ‘ordinary’ chronic urticaria. The latter is conventionally defined as the occurrence of daily or almost daily whealing for at least six weeks. The etiology of chronic urticaria is usually obscure. The different clinical varieties of chronic urticaria will be briefly considered here, and attention will be devoted to a newly emerged entity – autoimmune chronic urticaria, since establishing this diagnosis has conceptual, prognostic and the- rapeutic implications. Contact urticaria and angioedema without urticaria will not be dealt with in this account. Classification of Chronic Urticaria The clinical subtypes of chronic urticaria are illustrated in the pie-chart of Fig. 1. The frequency of these subtypes is based upon the authors’ experience at the St John’s Institute of Dermatology in UK. Whilst there may well be mi- nor differences, it is likely that the frequency distribution of these subtypes will be essentially similar in most centres in Europe and North America (Grea- ves 1995, 2000b). However, our experience suggests that the incidence of angioedema, especially that complicated by ordinary chronic urticaria is sub- stantially lower in Japan and south Asian countries (unpublished observation). 310 Michihiro Hide and Malcolm W. -

FULL TEXT BOOK Scientific Program Lecture Summaries Oral Presentations Poster Presentations 1 INVITATION Dear colleagues, We are pleased to announce the 5th INDERCOS Congress, taking place 12-15 March 2020 in İstanbul-TURKEY. The main topics of this meeting will be “Immunogenetics in Dermatology and Aging”. Through plenaries and parallel workshop sessions, we aim to share insights and experiences and discuss how advances in aesthetic and general dermatology. In order to success this, we have very distinctive international speakers with extensive experience and a range of expertise across aesthetic dermatology and dermatology. Several major histocompatibility complex and nonmajor histocompatibility complex genetic polymorphisms have been identified which may contribute to the inflammatory skin diseases and skin aging. Most of these genetic variants are associated with mechanisms attributed to the pathogenesis of skin disease and aging, including pathways involved in cytokines, chemokine and vitamin regulation and ultraviolet light exposure and other environmental factors. Immunogenetics is a subspeciality of medicine that studies the relationship between genetics and immunology. Immunogenetics helps in understanding the pathogenesis of several autoimmune, malign, infectious skin diseases and also skin aging. 5th INDERCOS congress focuses on the genetic research areas of autoimmune skin diseases such as connective tissue diseases, psoriasis, skin cancers, vasculitis, skin aging and skin infections. Lectures on genetics of cell interaction with immune system, immune response to transplantation, immune based therapies for treatment of cancers and inflammatory skin diseases and aging, antigenic phylogeny of alleles, alloantigens will be discussed. We hope you will be together with us in this fascinating, high quality scientifically educational congress and we look forward to your precious participation and feedback. -

Sensitization Against Skin Resident Fungi Is Associated with Atopy In
Altrichter et al. Clin Transl Allergy (2020) 10:18 https://doi.org/10.1186/s13601-020-00324-z Clinical and Translational Allergy RESEARCH Open Access Sensitization against skin resident fungi is associated with atopy in cholinergic urticaria patients Sabine Altrichter1 , Pia Schumacher1, Ola Alraboni1, Yiyu Wang1, Makiko Hiragun2, Michihiro Hide2 and Marcus Maurer1* Abstract Background: Cholinergic urticaria (CholU) is a common type of chronic inducible urticaria, characterized by small itchy wheals that appear upon physical exercise or passive warming. Malassezia globosa, a skin resident fungus, has been identifed as an antigen that induces mast cell/basophil degranulation and wheal formation through specifc IgE, in Japanese patients with atopic dermatitis and CholU. In this study we aimed in assessing the rate of IgE sensiti- zations against skin resident fungi in European CholU patients. Methods: We assessed serum IgE levels to Malassezia furfur, Candida albicans and Trichophyton mentagrophytes using routine lab testing and Malassezia globosa using a newly established ELISA. We correlated the results to wheal forma- tion and other clinical features. Results: Four patients (of 30 tested) had elevated levels of IgE against Malassezia furfur and Candida albicans and two had elevated levels of IgE against Trichophyton mentagrophytes. Four sera (of 25 tested) had elevated levels of IgE to the Malassezia globosa antigen supMGL_1304. Sensitization to one skin fungus was highly correlated with sensitiza- tion to the other tested fungi. We saw highly signifcant correlations of sensitization to supMGL_1304 with wheal size in the autologous sweat skin test (r 0.7, P 0.002, n 19), the Erlangen atopy score (r 0.5, P 0.03, n 19), total s = = = s = = = IgE serum levels (rs 0.5, P 0.04, n 19) and a positive screen for IgE against common airborne/inhalant allergens s (sx1; r 0.54, P 0.02,= n =19). -
