Management of allergic disease in the elderly: key considerations, recommendations and emerging therapies

The number of people over 65 is increasing around the world. At present, between 5 and 10% of allergic diseases affect the elderly. In particular, rhinitis is increasing worldwide; the presence of high comorbidity makes the therapy of asthma even more complicated. With reference to dermatological allergies, the dryness of the skin favors the onset of allergic contact and atopic dermatitis, while the senescence of mucous membranes and the impaired secretion of polymeric IgA could be linked to food allergy. Overcoming the problem of adverse drug reaction is limited by the diagnostic difficulty in patients taking multiple drugs. In addition, some drugs, such as β-blockers, angiotensin-converting enzyme (ACE)-inhibitors and NSAIDs, are relevant factors of urticaria and anaphylaxis. The aim of this review is to provide updated diagnostic and therapeutic guidelines through a better understanding of the pathophysiologic mechanisms, preventive measures and adherence to therapy.
