The behavior of Italian allergists in prescribing allergen immunotherapy for house dust mites allergy.

The meeting 'Clinical Evidence, Extracts Quality and Biotechnology Innovation in Allergen Immunotherapy' held in Trieste (Italy) on 1 October 2017 concerned the outcomes of a real-world survey conducted on a group of Italian allergists about allergen immunotherapy (AIT) for house dust mites allergy. It pointed out: allergist's confidence that AIT should be prescribed continuously; tablets seem to be well accepted by patients and effective in most subjects with a fast onset of action (3-6 months); combined score for symptom severity and medication use is universally assessed; there is disagreement about the diagnosis of house dust mites allergy, the quote of AIT prescription, the choice for AIT route of administration, assessment of serum IgE and perception of patient's adherence.
