- Brief summaryRespiratory syncytial virus (RSV) lower respiratory tract infection (LRTI) is the most frequent cause of bronchiolitis during infancy. During the winter season RSV bronchiolitis is one the most common causes of hospitalization. About 10% of hospitalized children with RSV LRTI require mechanical ventilation. Long-term airway morbidity occurs in about half of hospitalized infants with RSV LRTI, which is referred to as post-bronchiolitis wheeze (PBW). Good evidence exists that milder forms of RSV LRTI, which do not require hospital admission, are also associated with post-bronchiolitis wheeze. It has been shown that post-bronchiolitis wheeze is associated with decreased health-related quality of life over a broad range of domains.

Two non-excluding alternative hypotheses have been mentioned in the pathogenesis of RSV infection and post-bronchiolitis wheeze. First, it is possible that pre-existent pathology underlies both RSV infection and post-bronchiolitis wheeze (parallel hypothesis). It has been suggested that congenital decreased lung function precedes RSV infection. However, this still requires formal proof.

Prevention of severe RSV infection in preterm infants with gestational age <36 weeks is possible using monthly infection with palivizumab during the winter season. This effect of this humanized monoclonal antibody has been established in a large randomized controlled trial. In the Netherlands this drug is only used up to gestational age 32 weeks. Preterm children with gestational age 32-35 weeks are not prophylactically treated with palivizumab because of high costs.
It is not known whether recurrent wheeze in preterm children is caused by RSV infection (serial hypothesis) or that RSV infection is the first indication of chronic airway morbidity that would develop anyway (parallel hypothesis). This study aims to distinguish between these two hypotheses by investigating whether prevention of RSV (by palivizumab) results in decreased incidence of recurrent wheeze.

In this randomized controlled trial the number of wheezing days in the first year of life will be compared between infants receiving palivizumab and placebo. Definite results are expected in 2011.
