title: Predicting the long-term course of asthma in wheezing infants is still a challenge.
abstract: Background. In recurrent wheezing infants, it is important to identify those likely to remain asthmatic in order to propose appropriate long-term management. Objective. To establish predictive factors for persistent asthma at adolescence in a population of recurrent wheezing infants. Methods. Retrospective study of 227 infants. Inclusion criteria were age under 36 months, a history of at least three wheezing episodes assessed via a doctor-led ISAAC questionnaire and a standardized allergy testing programme. At 13 years, active asthma was assessed by questionnaire. Results. Risk factors for asthma persisting into adolescence were allergic sensitization to multiple airborne allergens (OR 4.6, CI-95% (1.9-11.2) P = 0.001), initial atopic dermatitis (OR 3.4, CI-95% (1.9-6.3) P < 0.001), severe recurrent wheezing (OR 2.3, CI-95% (1.3-4.2) P = 0.007), and hypereosinophilia ≥470/mm(3) (OR 2.2, CI-95% (1.07-4.7) P = 0.033). Conclusion. While it is still difficult to predict the long-term course of asthma, atopy remains the major risk factor for persistent asthma.
