NCT05889013

Brief Summary

This cross-sectional and longitudinal observational study is to gather data on the utility of tests that are used to make a diagnosis of primary ciliary dyskinesia (PCD). There is new testing available, called nasal nitric oxide testing, that non-invasively measures nitric oxide levels in the sinus cavity. Individuals with PCD characteristically have low levels, but this testing does not have extensive data from everyday clinical practice. The objective of this proposal is to improve the diagnostic approach to children and adults with clinical concerns for primary ciliary dyskinesia (PCD).

Outcome Measures

Primary Outcomes (2)

  • Creation of Nasal NO REDCap registry

    To establish a research registry to characterize the features of individuals that undergo PCD diagnostic testing at Connecticut Children's Medical Center and UCONN.

    2-3 years

  • Evaluation of utility of PCD diagnostic testing

    To evaluate the utility of PCD diagnostic testing, including potential use of nasal nitric oxide in comparison to genetic testing and ciliary biopsy, in pulmonary practice at Connecticut Children's Medical Center and UCONN.

    2-3 years

Secondary Outcomes (1)

  • Refinement and Improvement of PCD Diagnostic Testing

    1-2 years

Study Arms (1)

Nasal Nitric Oxide

Participants who are referred by his/her clinician for nasal NO testing and meet the inclusion and exclusion criteria will undergo testing. Clinical information regarding prior diagnostic testing will be collected at time of enrollment. Participants that have a confirmed diagnosis of PCD by genetics or ciliary biopsy at time of study entry

Device: Nasal Nitric Oxide testing

Interventions

Collection of already performed clinical data and nNO testing

Also known as: nNO testing
Nasal Nitric Oxide

Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

The target population are ages 2 and up. Participant selection will be on a referral basis for the consideration of a clinical suspicion for PCD. Participants will be identified by pulmonary providers that consider testing for PCD based on the clinical symptoms of the participant. These providers will thenrefer for enrollment in the study based on the clinical considerations for a diagnosis of PCD.

You may qualify if:

  • Age ≥ 2 years of age
  • Must have two of the following clinical history points:
  • Neonatal respiratory distress
  • Chronic nasal congestion/runny nose
  • Chronic cough
  • Situs/laterality defects
  • Bronchiectasis
  • Ability to provide informed consent or consent of parent/guardian and ass

You may not qualify if:

  • Recent history of sinus surgery or bloody nose in the past week
  • Age \< 2 years of age
  • Inability to tolerate probe in nose
  • Sinusitis or other respiratory exacerbation currently being treated with antibiotics
  • Admitted to hospital for respiratory exacerbation (inpatient status)
  • Inability to understand the requirements of the study or be unwilling to provide written informed consent (as evidenced by signature on an informed consent document approved by the IRB)
  • Any other reason for which the study investigators feel the patient is not a good candidate to complete the testing
