The evidence of efficacy of allergen immunotherapy (AIT) for respiratory allergy has been demonstrated by a number of meta-analyses. However, the daily practice of AIT is quite different from controlled trials, facing challenges in terms of selection of patients, practical performance, and, of particular importance, use of allergen extracts of inadequate quality. We here performed […]

Allergy diagnostics have changed in the last 10-15 y, moving from the use of extracts for in vivo and in vitro diagnosis to the Component Resolved Diagnosis, based on purified or recombinant allergens. As expected, aerobiology developed similarly, and measurement of allergens in both outdoor and indoor air is now feasible. With the aim of […]
Allergen immunotherapy (AIT) represents the only way to modify the natural history of allergic diseases. Unfortunately, AIT is not always followed by a reduction in symptoms. The main reasons for such failure can be inadequate diagnosis and/or the poor treatment. In both cases, an incomplete or insufficient understanding of the component (s) responsible for the […]
Relevant allergens are major contributors to the safety and efficacy of allergenic extracts used in allergen immunotherapy (AIT). As such, they should be accurately quantified, as recommended by the 2008 European guidelines on allergen products. Until now, the quantification of relevant allergens was mainly performed by using immunoassays (e.g. ELISA) that relying upon specific antibodies. […]
Many pharmaceutical and biotechnological products are temperature-sensitive and should normally be kept at a controlled temperature, particularly during transport, in order to prevent the loss of their stability and activity. Therefore, stability studies should be performed for temperature-sensitive products, considering product characteristics, typical environmental conditions, and anticipating environmental extremes that may occur during product transport […]
We performed a survey, based on a questionnaire including 20 items, submitted anonymously to Italian trainees in Allergology and Clinical Immunology, in order to obtain information about their specific allergen immunotherapy (AIT) practices. The questionnaire was sent to 40 trainees, who had attended the last two years of the training course. Thirty-four subjects (mean age: […]
In its century-long history, allergen immunotherapy (AIT), has shown continuous evolution in terms of the materials and the treatment schedules used, the adequate duration, and the mechanisms of action underlying its clinical efficacy. The passage from the empirical phase of AIT to the era of evidence-based medicine (EBM) was associated with achievement of the highest […]
