Hereditary Angioedema (HAE) is a rare and disabling disease. Early diagnosis and appropriate therapy are essential. This update and revision of the global guideline for HAE provides up-to-date consensus recommendations for the management of HAE. In the development of this update and revision of the guideline, an international expert panel reviewed the existing evidence and developed 20 recommendations that were discussed, finalized and consented during the guideline consensus conference in June 2016 in Vienna. The final version of this update and revision of the guideline incorporates the contributions of a board of expert reviewers and the endorsing societies. The goal of this guideline update and revision is to provide clinicians and their patients with guidance that will assist them in making rational decisions in the management of HAE with deficient C1-inhibitor (type 1) and HAE with dysfunctional C1-inhibitor (type 2). The key clinical questions covered by these recommendations are: 1) How should HAE-1/2 be defined and classified?, 2) How should HAE-1/2 be diagnosed?, 3) Should HAE-1/2 patients receive prophylactic and/or on-demand treatment and what treatment options should be used?, 4) Should HAE-1/2 management be different for special HAE-1/2 patient groups such as pregnant/lactating women or children?, and 5) Should HAE-1/2 management incorporate self-administration of therapies and patient support measures?

In Europe, allergen extracts are standardized based on skin prick wheal size in 20-30 allergic subjects. To understand the biological activity of clinically effective Sublingual immunotherapy, we used this method to determine the biological activity of solution and tablet Timothy grass pollen (TIM) extracts, compared to an FDA-approved extract (Reference) of 10 000 BAU/ml. Blinded, quadruplicate skin prick tests with concentrate and three serial half-log dilutions allowed the construction of a semilogarithmic regression line per extract. Bioequivalent allergy units (BAU) values were obtained from the comparison with reference. Extracts and dilutions showed a neat linear dose response (all: R > 0.98) in 33 rhinitis patients. Relative potencies: Staloral 12 000 BAU/ml, Soluprick 10 300 BAU/ml, Oralair 8200 BAU, and Grazax 6200 BAU. Even though all extract concentrates differed in wheal size (P = 0.01-0.001), Grazax producing a 25% smaller wheal size than Oralair , and the biological activity of these clinically effective TIM tablets led in the same range (6200-8200 BAU; 0.92-1.23 cm ). SLIT dose-finding studies for other pollens might start with allergen extracts producing 1.1 cm wheal surface.
La mayoría de los pacientes con rinitis alérgica no recibe el manejo idóneo, sino que se automedica. MASK (Mobile Airways Sentinel Network) forma parte integral de un proyecto apoyado por la Unión Europea contra las enfermedades crónicas y enfocado al envejecimiento activo y saludable. Constituye la tercera fase de ARIA (Allergic Rhinitis and its Impact on Asthma), en la cual mediante una aplicación móvil en un dispositivo inteligente se intenta guiar al paciente en el control de su multimorbilidad, rinitis o conjuntivitis alérgicas o asma. La aplicación Diario de Alergia por MACVIA-ARIA es gratuita y está disponible para Android e iOS. Al descargarla al celular del paciente, a este se le piden datos de su perfil, patologías alérgicas y medicación; posteriormente, mediante una escala visual analógica se le invita a determinar el grado de afectación en nariz, ojos y bronquios y su influencia sobre su productividad laboral/escolar. Con los datos del Diario de Alergia se observa que existe un nuevo patrón de presentación: rinitis alérgica + conjuntivitis alérgica + asma, con mayor afectación, así como un alto nivel de automedicación: en general, el paciente toma medicación cuando presenta síntomas. La app se ha desplegado en 23 países, incluyendo varios países hispanohablantes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
