PREVALENCE OF BRONCHIAL HYPERRESPONSIVENESS IN PRIMARY CILIARY DYSKINESIA

Overview
All people have tiny hairs that help move mucus through their air tubes. When these hairs do not form or do not work properly it can cause the air tubes to get clogged with mucus, which can cause PCD. The purpose of this study is to look at children with PCD and see if they have another condition called “bronchial hyperresponsiveness”. This is when some of the air tubes (“bronchi”) are very sensitive (“hyperresponsive”) to certain things in the environment such as pollen, mold, pet dander, changes in temperature, and viruses. Children with PCD are often prescribed a medicine to breathe in every day called steroids to help make their air tubes less sensitive, but there are not very many research studies showing that children with PCD really need this medication.
Description
Participants will be asked to complete two visits and be given the option to complete a third visit. During these visits, researchers will take participants' vitals, give them an overall physical examination, and give participants a breathing test called spirometry.
