It's Time to Start Phenotyping Our Patients with Asthma.

Advances in the management of pediatric asthma, including biologics, offer practitioners the ability to tailor therapies to individual patients. However, asthma treatment guidelines have not kept up with current studies. This review explores the current literature incorporating the use of phenotyping in pediatric patients with asthma to provide precision therapy. Biomarkers can be used to more accurately predict the development of asthma, identify features that may be associated with difficult-to-control or severe asthma, and forecast response to therapies. Biomarkers and other phenotypic data can also be helpful in patients with uncontrolled, severe asthma in the selection of a biologic therapy.
