Randomised placebo controlled trial of inhaled corticosteroids for treatment of chronic cough in children.

This study is testing whether a 2-week course of inhaled corticosteroids (steroid puffers) can speed up recovery from chronic cough in children. Chronic cough is defined as a cough lasting 4 weeks or more. Researchers are also testing whether a specific breathing test (FeNO — measuring nitric oxide in exhaled breath) can predict which children will respond best to this treatment. You may be eligible if: - Your child has a cough lasting 4 weeks or more - Your child is between 18 months and 16 years old - Your child is able to use an inhaler with a spacer device You may NOT be eligible if: - Your child received oral or inhaled steroids in the week before this study - Your child is unable to tolerate inhaled corticosteroids or use a spacer - Your child has cerebral palsy or a severe developmental disability - Your child has a confirmed chronic respiratory illness (e.g., asthma already diagnosed) - Your child has a weakened immune system Talk to your doctor about whether this trial might be right for you.
