title: [The effectiveness of montelukast in recurrent post-bronchiolitis wheezing].
abstract: Some studies showed increased levels of leukotrienes in the nasopharyngeal secretions in children with wheezing secondary to viral infections, leading to therapeutical attempts with leukotriene receptor inhibitors in infants and small children with recurrent wheezing. This is a double blind randomized study for evaluating the efficacy of montelukast in infants and small children. In the study group (20 children) treated with montelukast, 5 mg/day for 3 months, the frequency of bronchial obstruction episodes in the 6 months following the start of therapy was significantly lower (p = 0.001) than the 6 months before treatment (1.25 +/- 1.41 versus 3.79 +/- 2.41). In the control group (18 children) treated with placebo, the frequency of the bronchial obstruction episodes decreased (from 3.04 +/- 1 to 2.41 +/- 1.5) in the two analyzed periods, but the differences were not statistically significant (p = 0.067). The differences between the two groups are present also after excluding the children with atopy. The results suggest the beneficial role of leukotriene receptor antagonists in improving the symptoms of patients with recurrent post-bronchiolitis wheezing.
