Measuring nasal function in adults with chronic sinus symptoms
Part of Ear, nose & throat, Infections, Lungs & breathing clinical trials.
This study tests a specialized way of measuring how your nasal lining responds in people with chronic rhinosinusitis (long-lasting sinus inflammation). The goal is to see whether the nasal measurement is usable and safe, and to help better understand chronic sinus disease.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Be 19 years or older and weigh at least 50 kg
- Have chronic rhinosinusitis symptoms for at least 12 weeks and signs of inflammation (often checked by nasal endoscopy and sometimes a CT scan)
- Be able to do the nasal potential difference (NPD) testing
- Not be currently pregnant or breastfeeding (and have a negative pregnancy test if applicable)
- Have no major asthma flare in the last 2 months and be well enough to safely participate

This study looks at chronic rhinitis (long-term stuffy or runny nose) in Chinese adults. It aims to understand how common it is and what causes it.
This study is a registry that tracks how well treatments work for people with chronic rhinosinusitis with nasal polyps. By joining, you help doctors learn which therapies lead to better control and possibly remission of symptoms over time.
This study looks at the substances in nasal fluids from people with chronic rhinitis to better understand the condition and find new ways to diagnose it. You provide a free sample and answer some questions.
This study uses a nasal allergen provocation test to help diagnose chronic rhinitis more accurately. If you have allergic rhinitis or are a healthy volunteer, you may help researchers learn how well this test works.
