Childhood allergic rhinitis predicts asthma persistence in adults

Most patients with asthma have rhinitis suggesting the concept of ‘one airway one disease’ or ‘united airways’. However, not all patients with rhinitis present with asthma.

The association between allergic rhinitis and asthma is well documented, but the temporal sequence of this association has not been closely examined.

According to a recent literature review, childhood allergic rhinitis was associated with a 2- to 7-fold increased risk of asthma in preadolescence, adolescence, or adult life.

Childhood allergic rhinitis was associated with a 3-fold increased risk of childhood asthma persisting compared with remitting by middle age. Asthma burden in later life might be reduced by more aggressive treatment of allergic rhinitis in early life.
