Real-life evidence in allergen immunotherapy: Moving forward with mHealth apps.

AIM

The efficacy and safety of allergen immunotherapy (AIT) in allergic rhinitis has been classically assessed using randomized controlled trials (RCTs). However, RCTs may have limitations in their external validity, and their evidence may be complemented with that from real-world studies. We aimed to review the mHealth apps that can be used for retrieving real-world data on AIT in allergic rhinitis.

MATERIALS AND METHODS

We applied an automatic tool to identify the mHealth apps (available in the Google Play and Apple App stores) that can be used to assess patients under AIT for allergic rhinitis. Apps meeting the inclusion criteria were reviewed, and the corresponding scientific evidence was assessed.

RESULTS

We identified five apps with scientific publications in the context of allergic rhinitis: AirRater, AllergyMonitor, MASK-air, Husteblume, and Pollen App. Of those, only MASK-air and AllergyMonitor assessed AIT in patients with allergic rhinitis. MASK-air has enabled the comparison of reported symptoms among patients treated vs. not-treated with AIT. MASK-air has also allowed for the development of combined symptom-medication scores that can be used as endpoints for AIT trials. AllergyMonitor has identified that mobile technology can improve adherence to AIT and is set to support the prescription of AIT for patients with allergic rhinitis by a more precise identification of the pollen season.

CONCLUSION

Mobile health tools allow for the collection of large volumes of real-world data and can be useful for generating hypotheses on AIT. However, such hypotheses require confirmation by epidemiological studies and RCTs.
