Preschool Wheeze: Inflammation/Infection Guided Management

This is a single-centre, randomised-controlled trial, comparing management of preschool wheeze. It specifically aims to compare management of preschool wheeze using current clinical guidelines to management determined by eosinophilic inflammation and infection. Participants will be children aged 1-5 years who have recurrent wheezing and will be allocated to one of two treatment groups, either current clinical care or pathological phenotype based management. They will be asked to make 2 study visits to the Royal Brompton Hospital over the course of 4 months.
