In a study published in the Journal of the Japanese Society of Allergy (Arerugi) last June, authors investigated whether, in infants and young children who experienced their first episode of wheezing, abnormal findings of allergological examination were present and could predict the development of asthma.
They noticed that these children had higher levels in some parameters (i.e. eosinophils, IgE, etc.) than normal children. But additionally, during the follow-up period of one year and 9 months on average, the incidence of wheezing episodes was also significantly higher in the patients with those previous high parameters.
CONCLUSION: These results suggest that it is convenient to conduct allergological examination even in infants and young children, who have had wheezing episode for the first time, for the purpose of providing against the subsequent occurrence of asthma
