Check for undiagnosed PCD in adults with bronchiectasis

Official title: Novel Use of Combined High-Speed Video Microscopy and Nasal Nitric Oxide Screening for Identification of Primary Ciliary Dyskinesia in Adult Bronchiectasis

Run by Indiana University · NCT07566611 · Data updated 2026-11-12

This study tests whether nasal nitric oxide measurement and nasal samples can help find previously undiagnosed primary ciliary dyskinesia in adults with bronchiectasis.

Is this trial a fit for you?

Likely a good fit

Adults aged 18 and older with CT-confirmed bronchiectasis who have not been diagnosed with cystic fibrosis or primary ciliary dyskinesia and can complete the testing procedures.

Probably not a fit

Individuals unable to perform the required testing or who already have a confirmed diagnosis of PCD or CF may not benefit from the study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Adults with CT-confirmed bronchiectasis will undergo nasal nitric oxide testing and analysis of nasal samples to identify undiagnosed primary ciliary dyskinesia. The study focuses on how often PCD is present but unrecognized in this population, acknowledging that many cases lack a clear cause. High-speed video microscopy analysis, a key diagnostic tool for PCD, is highlighted as part of the assessment approach. Results could improve targeted management and genetic counseling for affected patients. No comparator group or traditional randomized design is described in this protocol.

Why it matters

Potential benefit: Identifying undiagnosed PCD could lead to more personalized care and better disease prognosis for adults with bronchiectasis.

How similar studies have gone: There is prior evidence that PCD testing can reveal undiagnosed cases in bronchiectasis, though the approach combining nNO and HSVA in adults with non-CF bronchiectasis is less established.
