nNO Testing for Primary Ciliary Dyskinesia
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to find better ways to diagnose Primary Ciliary Dyskinesia (PCD), a rare genetic disorder affecting breathing. It evaluates the effectiveness of current tests, such as nasal nitric oxide (nNO) testing, for diagnosing this condition. The trial gathers key health data and performs nNO tests on some participants. It suits individuals referred for PCD diagnosis who can follow the study procedures. As an unphased trial, it offers participants the chance to contribute to important research that could enhance diagnostic methods for PCD.
Do I need to stop my current medications for the trial?
The trial information does not specify whether you need to stop taking your current medications.
What prior data suggests that these PCD diagnostic tests are safe?
Research has shown that testing nasal nitric oxide (nNO) is generally safe. This test measures the amount of nitric oxide in the nose and aids in diagnosing primary ciliary dyskinesia (PCD), a rare genetic disorder. Studies have found that individuals with PCD usually have lower nNO levels, making this test useful for identifying the condition.
Importantly, nNO testing is easy to tolerate, with most people experiencing no discomfort or side effects. It does not involve needles or invasive procedures, which many find reassuring. So far, there have been no major reports of negative effects, making nNO testing a safe choice for those considering participation in clinical trials or screening for PCD.12345Why are researchers excited about this trial?
Researchers are excited about nasal nitric oxide (nNO) testing for Primary Ciliary Dyskinesia (PCD) because it offers a non-invasive way to diagnose this rare genetic disorder. Unlike traditional methods like genetic testing or ciliary biopsy, which can be invasive and time-consuming, nNO testing is quick and easy, providing immediate results. This method not only helps in confirming PCD but also aids in ongoing monitoring of the condition, making it a potentially game-changing tool for both patients and healthcare providers.
What evidence suggests that nasal nitric oxide testing is effective for diagnosing Primary Ciliary Dyskinesia?
Research has shown that measuring nasal nitric oxide (nNO) levels is useful for diagnosing primary ciliary dyskinesia (PCD). Studies have found that individuals with PCD typically exhibit very low nNO levels, making this test a simple and non-invasive diagnostic tool. In this trial, participants will undergo nNO testing, and researchers will collect clinical data to evaluate its effectiveness in diagnosing PCD. The consistently low nNO levels in PCD patients offer a reliable indicator for detection, aiding doctors in identifying PCD early and accurately.678910

Trial Overview
The study is evaluating the effectiveness of current diagnostic tests for PCD, focusing on nasal nitric oxide (nNO) testing, which measures the amount of nitric oxide in breath as an indicator of ciliary function.
How Is the Trial Designed?
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
