Paediatric respiratory reviews

The inability to accurately predict the outcome of infants with recurrent wheezy bronchitis makes the early use of inhaled corticosteroids (ICS) controversial. Data from bronchoalveolar lavages and epidemiological surveys suggest a persistent inflammation of the airways in the more severe cases. ⋯ In infants with episodic viral-associated wheeze with or without interval symptoms, ICS use carries the risk of overtreatment and of adverse effects. Long-term prospective studies are urgently required to assess the efficacy and safety of ICS and their possible effects on the natural history of infantile asthma.
