Bilastine for the treatment of allergic rhinoconjunctivitis and urticaria: results from an international Delphi study.

Background: Second-generation oral H1-antihistamines, including bilastine, represent the emerging treatments of allergic rhinitis (including rhinoconjunctivitis) and chronic urticaria in both adults and children. This study analyses available evidence supporting the use of bilastine amongst second-generation antihistamines for the symptomatic treatment of allergic rhinitis and urticaria in adults and children. Methods: Consensus amongst experts from 17 countries on the ideal treatment of rhinitis and urticaria, and the specific role of bilastine was measured by means of a modified Delphi process. A total of 12 statements were voted on by the experts using a five-point Likert scale (1 = strongly disagree; 2 = disagree; 3 = undecided; 4 = agree; 5 = strongly agree). The definition of consensus was set at a minimum of 80% concordance for 4+5 scores (agree or strongly agree). Results: All proposed statements reached consensus, with a concordance of ≥98% for five statements and ≥96% for seven. Conclusions: The wide consensus obtained for the proposed statements suggests a prominent role for bilastine in the management of allergic rhinitis and urticaria.

Digitally-enabled, person-centred care (PCC) in allergen immunotherapy: An ARIA-EAACI Position Paper.

In rhinitis and asthma, several mHealth apps have been developed but only a few have been validated. However, these apps have a high potential for improving person-centred care (PCC), especially in allergen immunotherapy (AIT). They can provide support in AIT initiation by selecting the appropriate patient and allergen shared decision-making. They can also help in (i) the evaluation of (early) efficacy, (ii) early and late stopping rules and (iii) the evaluation of (carried-over) efficacy after cessation of the treatment course. Future perspectives have been formulated in the first report of a joint task force (TF)-Allergic Rhinitis and Its Impact on Asthma (ARIA) and the European Academy of Allergy and Clinical Immunology (EAACI)-on digital biomarkers. The TF on AIT now aims to (i) outline the potential of the clinical applications of mHealth solutions, (ii) express their current limitations, (iii) make proposals regarding further developments for both clinical practice and scientific purpose and (iv) suggest which of the tools might best comply with the purpose of digitally-enabled PCC in AIT.

Polysensitisation is associated with more severe symptoms: The reality of patients with allergy.

BACKGROUND: Studying the sensitisation profiles of patients with allergies allows for a deeper understanding of the disease which may facilitate the selection of the best-personalised allergen immunotherapy. This observational, cross-sectional, multicentre study aimed to demonstrate the heterogeneity of the German population with allergies by analysing specific immunoglobulin E (sIgE) patterns towards aeroallergens and exploring the relationship between sensitisation and clinical symptoms. METHODS: In total, 500 patients with allergies from different regions of Germany were recruited based on their case histories, clinical allergic symptoms and skin prick test data for aeroallergens. Serum samples were analysed using ImmunoCAP assays to determine sIgE levels for 33 allergenic sources and 43 molecular allergens. RESULTS: Most patients (81%) were polysensitised. Betula verrucosa pollen was the most common cause of sensitisation (59%), followed by Phleum pratense (58%) and Dermatophagoides pteronyssinus (44%). The highest prevalence rates of molecular allergens were observed for Bet v 1 (84%) from birch pollen, Phl p 1 from grass pollen (82%), Der p 2 (69%) from mites and Fel d 1 (69%) from cat. Polysensitisation was significantly associated with the presence of asthma and the severity of rhinitis symptoms. CONCLUSIONS: Our findings show a high rate of polysensitisation and emphasise the importance of molecular diagnosis for more precise and comprehensive insights into sensitisation patterns and their association with clinical symptoms. These data may help improve personalised diagnosis and immunotherapy adapted to the needs of individual patients in the region.
