 Global Trends in Anaphylaxis Epidemiology and Clinical Implications

Abstract


The true global scale of anaphylaxis remains elusive, because many episodes occur in the community without presentation to health care facilities, and most regions have not yet developed reliable systems with which to monitor severe allergic events. The most robust data sets currently available are based largely on hospital admissions, which are limited by inherent issues of misdiagnosis, misclassification, and generalizability. Despite this, there is convincing evidence of a global increase in rates of all-cause anaphylaxis, driven largely by medication- and food-related anaphylaxis. There is no evidence of parallel increases in global all-cause anaphylaxis mortality, with surprisingly similar estimates for case-fatality rates at approximately 0.5% to 1% of fatal outcomes for hospitalizations due to anaphylaxis across several regions. Studying regional patterns of anaphylaxis to certain triggers have provided valuable insights into susceptibility and sensitizing events: for example, the link between the mAb cetuximab and allergy to mammalian meat. Likewise, data from published fatality registers can identify potentially modifiable risk factors that can be used to inform clinical practice, such as prevention of delayed epinephrine administration, correct posturing during anaphylaxis, special attention to populations at risk (such as the elderly on multiple medications), and use of venom immunotherapy in individuals at risk of insect-related anaphylaxis.

    Muchos episodios de anafilaxia ocurren en la comunidad sin que se presenten en los centros de atención médica, por lo que su epidemiologia es difícil de determinar, ademas que la mayoría de las regiones aún no han desarrollado sistemas confiables para monitorear eventos alérgicos graves. Los datos más sólidos actualmente disponibles se basan en gran medida en los registros hospitalarios, que están limitados por cuestiones inherentes de diagnóstico erróneo y clasificación errónea. A pesar de esto, existe evidencia convincente de un aumento global en las tasas de anafilaxia por todas las causas, en gran medida por la anafilaxia relacionada con los medicamentos y los alimentos. Cabe recalcar la falta del conocimiento medico acerca del tema, enlazo estudio de interes realizado por el servicio de Alergologia clínica UdeA en cabeza del Dr Ricardo Cardona https://revistaalergia.mx/ojs/index.php/ram/article/view/524/1015

ICON: Diagnosis and management of allergic conjunctivitis. Miércoles 25 de marzo

ICON: Diagnosis and management of allergic conjunctivitis. Authors: Bielory L1, Delgado L2, Katelaris CH3, Leonardi A4, Rosario N5, Vichyanoud P6. Author information Abstract Ocular allergy (OA), interchangeably known as allergic conjunctivitis, is a common immunological hypersensitivity disorder affecting up to 40% of the population. Ocular allergy has been increasing in frequency, with symptoms of itching, redness, and swelling that significantly impacts an individual's quality of life (QOL). Ocular allergy is an often underdiagnosed and undertreated health problem, because only 10% of patients with OA symptoms seek medical attention, whereas most patients manage with over-the-counter medications and complementary nonpharmacological remedies. The clinical course, duration, severity, and co-morbidities are varied and depend, in part, on the specific ocular tissues that are affected and on immunologic mechanism(s) involved, both local and systemic. It is frequently associat...

 Instructivo para la vigilancia en salud pública intensificada de infección respiratoria aguda asociada al nuevo coronavirus 2019 (COVID-19).  Fecha de actualización: viernes 20 de marzo 2020 Versión: 7 1. Introducción El 31 de diciembre de 2019 la Comisión Municipal de Salud y Sanidad de Wuhan (provincia de Hubei, China) informó sobre un agrupamiento de 27 casos de neumonía de etiología desconocida con inicio de síntomas el 8 de diciembre; los casos reportaban antecedente de exposición común a un mercado de mariscos, pescados y animales vivos en la ciudad de Wuhan. El 7 de enero de 2020, las autoridades chinas identificaron como agente causante del brote un nuevo tipo de virus de la familia Coronaviridae, que fue denominado “nuevo coronavirus”, SARS-COV-2 (1). Dado que los casos de coronavirus suelen causar síntomas respiratorios, la Organización Mundial de la Salud (OMS) ha emitido recomendaciones de protec...

BCG Vaccination Enhances the Immunogenicity of Subsequent Influenza Vaccination in Healthy Volunteers: A Randomized, Placebo-Controlled Pilot Study. Martes 14 de abril

BCG Vaccination Enhances the Immunogenicity of Subsequent Influenza Vaccination in Healthy Volunteers: A Randomized, Placebo-Controlled Pilot Study Authors: Jenneke Leentjens 1, Matthijs Kox 2, Robin Stokman 2, Jelle Gerretsen 2, Dimitri A Diavatopoulos 3, Reinout van Crevel 4, Guus F Rimmelzwaan 5, Peter Pickkers 2, Mihai G Netea 4 Abstract Background: Influenza-related morbidity and mortality remain high. Seasonal vaccination is the backbone of influenza management but does not always result in protective antibody titers. Nonspecific effects of BCG vaccination related to enhanced function of myeloid antigen-presenting cells have been reported. We hypothesized that BCG vaccination could also enhance immune responses to influenza vaccination. Methods: Healthy volunteers received either live attenuated BCG vaccine (n = 20) or placebo (n = 20) in a randomized fashion, followed by intramuscular injection of trivalent influenza vaccine 14 days later. Hemagglutination-inhibiting (H...
