Utility of PCD Diagnostics to Improve Clinical Care

June 28, 2025 updated by: Michael O'Connor, Vanderbilt University Medical Center
This is a study evaluating the utility of current Primary Ciliary Dyskinesia (PCD) diagnostic tests, including nasal nitric oxide testing.

Intervention / Treatment

Detailed Description

This study is a prospective data collection of individuals referred to the investigators clinical center for considerations of PCD. Participants sign informed consent to have clinical information entered into a secure electronic database. As part of this study, participants may have nasal nitric oxide (nNO) testing performed. nNO testing is a research procedure, but it is a test with growing utility for making a diagnosis of PCD when performed in the right clinical setting.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Other: Nasal Nitric Oxide testing and collection of clinical data
Participants will have nNO testing is indicated. All participants in this study have some basic clinical data collected at time of enrollment. Participants with a confirmed diagnosis of PCD or in those participants with a working diagnosis of PCD in which ongoing nNO testing is performed have prospective data collection. Some participants have a confirmed diagnosis of PCD by genetics or ciliary biopsy at time of study entry and thus do not need nNO testing, but are followed prospectively with collection of basic clinical data
Collection of already performed clinical data and nNO testing
