Summary

This study is looking for 530 adults with hay fever in South-Eastern Australia to help create a tool that predicts thunderstorm asthma. Participants will have allergy and lung function tests, then track their symptoms during spring for two years. The goal is to find warning signs (biomarkers) so doctors can advise protective treatments before asthma attacks happen.

Dec 2030

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: Consenting adults aged 18 to 70 years with seasonal allergic rhinitis willing to undertake: * Lung function testing * Blood sample collection for risk factor identification, -Prospectively logging their symptoms and medications through the springtime season using the CARISTA symptom monitoring platform . - Exclusion Criteria: * Individuals unable to provide informed consent * Individuals who do not suffer from symptoms of seasonal allergic rhinitis * Individuals who do not consent to lung function testing and blood sample collection - Individuals with unstable asthma (FEV1 by spirometry less than 70% predicted), a recent exacerbation or change of asthma preventive medication use (within one month) would be excluded, although re-screening would be permitted after one month, time permitting. * Individuals with severe asthma requiring the use of continuous oral corticosteroids or biological medication for severe asthma. * The presence of any medical illness, such as cardiac disease, pre-existing illness or immunomodulatory therapy that, in the opinion of the Investigators, would compromise participant safety or the derivation of biomarkers during the study.
