How best to diagnose asthma in infants and toddlers?

Abstract

No reliable way exists to diagnose asthma in infants and toddlers. Recurrent wheezing, especially apart from colds, combined with physician diagnosed eczema or atopic dermatitis, eosinophilia, and a parental history of asthma, increase the probability of a subsequent asthma diagnosis in the absence of other causes (strength of recommendation: B, 2 good-quality cohort studies).
