Drivers Of Childhood Asthma More Complex Than Thought

TUESDAY, Aug. 12, 2025 (HealthDay News) — Asthma flare-ups in children might be more complicated than previously thought, with hidden forces combining to restrict their airways, a new study says.

About 50% to 60% of children with severe asthma have a type called eosinophilic asthma, which are driven by white blood cells called eosinophils.

Treatment of eosinophilic asthma typically involves quelling type 2 (T2) inflammation, an immune response that promotes the production and activation of eosinophils, researchers said in background notes.
