In daily clinical routine, experimentally, or when measuring therapeutic success clinically, nasal allergen challenge is fundamental. It is further one of the key diagnostic tools when initiating specific allergen immunotherapy. So far, national recommendations offered guidance on its execution; however, international divergence left many questions unanswered. These differ…

Manifesto on small airway involvement and management in asthma and chronic obstructive pulmonary disease: an Interasma (Global Asthma Association - G…

2016

International audience; Evidence that enables us to identify, assess, and access the small airways in asthma and chronic obstructive pulmonary disease (COPD) has led INTERASMA (Global Asthma Association) and WAO to take a position on the role of the small airways in these diseases. Starting from an extensive literature review, both organizations developed, discussed, and approved the manifesto, which was subsequently approved and endorsed by the chairs of ARIA and GA2LEN. The manifesto describes the evidence gathered to date and defines and proposes issues on small airway involvement and management in asthma and COPD with the aim of challenging assumptions, fostering commitment, and bringin…

Interruption of CD28-mediated costimulation during allergen challenge protects mice from allergic airway disease

2012

Background Allergic asthma is a T H 2-promoted hyperreactivity with an immediate, IgE, and mast cell–dependent response followed by eosinophil-dominated inflammation and airway obstruction. Objective Because costimulation by CD28 is essential for T H 2 but not T H 1 responses, we investigated the effect of selective interference with this pathway in mice using the models of ovalbumin and house dust mite–induced airway inflammation. Methods To study the role of CD28 in the effector phase of allergic airway inflammation, we developed an inducibly CD28-deleting mouse strain or alternatively used a CD28 ligand-binding site–specific mouse anti-mouse mAb blocking CD28 engagement. Results We show …

SLIT's Prevention of the Allergic March.

2018

PURPOSE OF REVIEW: The progression of atopic disorders from atopic dermatitis in infants to allergic rhinitis and asthma in children, adolescents, and adults defines the allergy march. Allergen immunotherapy is the only causal treatment altering the immunological mechanism underlying the allergic diseases. The sublingual administration route is more acceptable than the subcutaneous one in pediatric age. RECENT FINDINGS: Several studies show the efficacy and safety profile of sublingual immunotherapy (SLIT) for the treatment of respiratory allergy diseases, but few data are available on its effect of primary and secondary prevention of allergic disease. The purpose of this manuscript is to r…

Immunologische Grundlagen der allergischen Spätreaktion

1965

An transferaktiven Zellen von tb-sensibilisierten Tieren sind mindestens zwei distinkte zellstandige Antikorper nachweisbar. Eine Art dieser Antikorper ist gegen Tuberkulopolysaccharid und die andere gegen Tuberkuloprotein gerichtet. Sie haben beide nach Kontakt mit dem Antigen die Fahigkeit, Komplement zu binden. Eine Cytolyse kommt sowohl durch eine zellstandig ablaufende Immunreaktion zwischen Polysaccharid-Antikorper und Tuberkuloprotein-Antikorper mit dem Antigen zustande, jedoch ist dazu nur im letzteren Falle Komplement erforderlich. Nach Kontakt mit dem Antigen ist also beim Polysacharid-Antikorper eine Komplementbindung moglich, fur eine Cytolyse aber nicht notig. Die beiden zellst…

Antigens of <i>Euparipha pisana</i> (Snail)

1988

The data obtained in this study suggest that eating <i>Euparipha pisana</i> (snail), a common food in Mediterranean countries, could give serious allergic reaction such as asthma. We describe here the identification and partial characterization of allergenic molecules form this new source. An aqueous extract of snail was obtained by homogenization in distilled water, centrifugation, dialysis and defatting with ethyl ether. Skin prick test (SPT) performed with the snail extract on 70 subjects allergic to the more common allergens of the Mediterranean area gave a SPT positivity in 61% of the subjects tested, with a mean value of histamine-equivalent prick (HEP) equal to 0.81 ± 0.2…

Analysis of a database to predict the result of allergy testing in vivo in patients with chronic nasal symptoms and the development of the software A…

2014

Background. This thesis consist of parts(i)Introduction in wich we present the clinical problem of rhinitis;(ii)the methods to evaluate the diagnostic choises;(iii)the rational errors in Allergy,(iv)the experimental part of thesis with wich we developed the software ARTSTAT,wich is the application of the analysis reported.Objective: We studied the ability of the logistic regression model obtained by the evaluaqtion of a database, to detect patients with positive allergy skin prick test(SPT)and patients with negative SPT. The model developed was valitated using the data set obtained from another medical institution. Methods: The analysis was carried out using a database obtained from a quest…

The future outlook on allergen immunotherapy in children: 2018 and beyond

2018

Abstract Allergen immunotherapy (AIT) is the only currently available immune-modifying and aetiological treatment for patients suffering from IgE-mediated diseases. In childhood, it represents a suitable therapeutic option to intervene during the early phases of respiratory allergic diseases such as rhino-conjunctivitis and asthma, which is when their progression may be more easily influenced. A growing body of evidence shows that oral immunotherapy represents a promising treatment option in children with persistent IgE- mediated food allergy. The efficacy of AIT is under investigation also in patients with extrinsic atopic dermatitis, currently with controversial results. Furthermore, AIT …

The Role of Mobile Health Technologies in Stratifying Patients for AIT and Its Cessation: The ARIA-EAACI Perspective.

2020

Allergen immunotherapy (AIT) is a proven therapeutic option for the treatment of allergic rhinitis and/or asthma. Many international or national practice guidelines have been produced, but the evidence-based method varies and they do not usually propose care pathways. The present article considers the possible role of mobile health in AIT for allergic rhinitis/asthma. There are no currently available validated biologic biomarkers that can predict AIT success, and mobile health biomarkers have some relevance. In the current article, the following aspects will be discussed: patient stratification for AIT, symptom-medication scores for the follow-up of patients, clinical trials, as well as the…
