ABSTRACT
Introduction
Pollen-induced allergic rhinitis (PIAR) is a widespread disease in children, and its prevalence is rapidly evolving. In addition, it may be associated with other atopic diseases, in particular asthma. In most cases, PIAR can be treated effectively by avoiding exposure to responsible allergens and using symptomatic treatments, including intranasal/oral antihistamines or/and nasal corticosteroids, according to ARIA guidelines. In recent decades, new medicines have been studied and developed: allergen-specific immunotherapy (AIT), anti-IgE antibodies, and probiotics. In addition, nutraceuticals have also been used as add-on treatments. This review aims to discuss and compare the old and new therapeutic strategies for PIAR in children.
Areas covered
Allergic rhinitis is a type 2 inflammatory disease. The management of patients with PIAR entails medications, AIT, and ancillary therapies. In addition, children with PIAR and associated severe asthma may be inclusively treated with biologics. Namely, subjects with allergic comorbidities could benefit from biological agents. However, AIT presently remains the unique causal treatment for PIAR.
Expert opinion
New strategies may include combined treatments, mainly concerning fixed associations with antihistamines and corticosteroids, nutraceutical products, and new AIT formulations.
Article highlights
Pollen-induced allergic rhinitis is a common disease characterized by typical symptoms and inflammatory reaction.
Different therapeutic strategies are available, including antihistamines, corticosteroids, allergen immunotherapy, and nutraceuticals.
Pharmacologic treatments are effective and generally safe but are not a resolutive strategy.
Allergen-specific immunotherapy is the only curative therapy still now.
Nutraceuticals could represent an attractive add-on therapy.
