Randomized Controlled Trial Multicenter StudyTiotropium in asthmatic adolescents symptomatic despite inhaled corticosteroids: a randomised dose-ranging study.
Tiotropium, a once-daily long-acting anticholinergic agent, has been shown to be an efficacious and safe add-on treatment for adults with symptomatic asthma, despite treatment with inhaled corticosteroids (ICS). A large proportion of asthmatic adolescents have symptomatic disease despite a wide range of therapeutic options. We investigated the efficacy and safety of three doses of tiotropium, administered in the evening (via Respimat(®) SoftMist™ inhaler), versus placebo in asthmatic adolescents symptomatic despite ICS treatment. ⋯ This first study of tiotropium in adolescents with symptomatic asthma demonstrates that tiotropium is well tolerated and efficacious as add-on to maintenance treatment with ICS. ClinicalTrials.gov identifier; NCT01122680.

Randomized Controlled Trial Multicenter StudyRepeated dyspnea score and percent FEV1 are modest predictors of hospitalization/relapse in patients with acute asthma exacerbation.
(1) Compare ideal cut-off points for DS and %FEV1 at 1 and 3 h to predict hospitalization/relapse in subjects with moderate to severe asthma exacerbation (2) Develop a multivariate regression model using DS, %FEV1, demographic, and clinical variables to predict hospitalization/relapse. ⋯ The 3-h score for %FEV1 and DS performed better than scores at any other time point and better than either parameter over time. The 3-h DS had the greatest association with the composite outcome. Neither test was a strong enough predictor to be used solely for this purpose.
