NCT05287022

Brief Summary

this study is aiming at learning more about primary ciliary dyskinesia (PCD) and tests that are used to diagnose this condition. One purpose of this study is to measure the level of nitric oxide in the nasal passages and examine how often the results correlate with other tests currently done to make the diagnosis.

Outcome Measures

Primary Outcomes (1)

  • Measuring nasal nitric oxide in comparison to ciliary biopsy and genetic testing for the diagnosis of PCD

    Individuals with PCD have characteristically low values of nNO; values below an established cut-off of 77nL/min are strongly associated with PCD in compatible clinical settings. These values are not well established for individuals who are in 2-5 years of age. nNO measurements (in nL/min) in 2-5 years of age will be compared to the diagnosis of PCD and assessed to establish diagnostic cut-offs.

    throughout the study, an average of 3 years

Secondary Outcomes (1)

  • Comparing tidal breathing to resistor method

    throughout the study, an average of 3 years

Study Population

Participants will include individuals who are diagnosed with PCD or undergoing work-up for primary ciliary dyskinesia based on their clinical symptoms as determined by the primary pulmonologist or other specialist

You may qualify if:

  • Individuals who are diagnosed with Primary Ciliary Dyskinesia OR
  • Individuals with abnormal PCD diagnostics (abnormal ciliary biopsy or PCD genetics) OR
  • Individuals with unexplained bronchiectasis OR
  • Individuals undergoing PCD diagnostic testing (ciliary biopsy, PCD genetic testing) or concern based on clinical symptoms (at least two of the following):
  • Neonatal respiratory distress
  • Organ laterality defects
  • Year-round cough starting in first year of life or bronchiectasis on chest CT
  • Year-round nasal congestion starting in first year of life or pansinusitis
  • Multiple ear infections in the first two years of life with sequelae (e.g. ear tubes, chronic effusion, abnormal audiological exam)
  • History of recurrent pneumonias (at least 2 in one year or more than 3 at any time)
  • Ability to provide consent for participation in study by the participants or guardian
  • Ability to perform the test
  • Age \>= 2 years of age

You may not qualify if:

  • Individuals who are unable to understand the requirements of the study.
  • Individuals (or guardians) who are unwilling to provide consent.
  • Individuals who are unable to complete the testing
  • Recent history of sinus surgery (within four weeks) or bloody nose (within one week) of testing (they can be included at a later date)
  • Patients who are currently being treated (within one week) with antibiotics for sinusitis or respiratory symptoms (they can be included at a later date)
  • Age \<2 years of age
