House dust mites-driven allergic rhinitis: could its natural history be modified? Expert Rev Clin Immunol. 2021 Jan 20;: Authors: Ciprandi G, Tosca MA Abstract INTRODUCTION: Allergic rhinitis (AR) is the most common IgE-mediated disease. House dust mites (HDM) sensitization is the main cause of AR. HDM-driven AR is characterized by a typical natural history consisting of possible progression to asthma. Allergen Immunotherapy (AIT) is, at present, a unique treatment to modify the natural history of allergic diseases. Tablets AIT (TAIT) represents a new era in AIT. There is evidence that TAIT could prevent asthma in AR patients. AREAS COVERED: The literature search methodology was based on the articles cited by PubMed from 1980 to 2020. AIT's rationale is to restore an immunological and, consequently, clinical tolerance toward the causal allergen. Namely, allergy is characterized by a specific and functional defect of tolerogenic mechanisms. The progression from rhinitis to asthma may be influenced by a relevant risk factor, such as the persistent type 2 inflammation of airways. HDM are perennial allergens and allergen exposure is the condicio sine qua non to maintain inflammation. AIT could modify the progression toward asthma restoring physiologic immune response to the causal allergen and consequently dampening type 2 inflammation. EXPERT OPINION: : Patients with HDM-driven AR are susceptible to develop asthma over t...
