Why smell may change after COVID-19: a nose tissue study
Part of Brain & nervous system, Infections, Lungs & breathing clinical trials.
This study looks at why some people lose or change their sense of smell after COVID-19. Researchers will take a tiny sample of tissue from your nose to study the cells and molecules involved.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must have had COVID-19 and now have lasting smell problems (like things smelling wrong or not smelling much at all).
- You must be willing to have a small biopsy (tissue sample) taken from your nasal passages for research.
- You cannot have other nose conditions (like sinusitis, polyps, or a deviated septum) that could affect your smell.
- You cannot be taking blood thinners (anticoagulants).
- You cannot be allergic to numbing medicines (local anesthetics).

This study tests a new way of doing smell training to help people whose sense of smell has not recovered after a viral illness. It may help you smell things better again.
This trial studies how smell testing might affect your health. You'll take part in online sessions where you smell different scents and answer questions.
This study tests whether a special smell training program can help people with chronic sinusitis improve their sense of smell after sinus surgery. If you have ongoing smell loss three months after surgery, you may be able to join.
This study looks at how smell (olfactory function) changes with age in healthy adults. If you're 50 or older, you may be able to join to help researchers understand age-related changes in smell.
This study looks at why people with nasal polyps lose their sense of smell and how it might come back. You may be able to join if you have had nasal blockage, runny nose, smell loss, or facial pain for at least 12 weeks, have polyps seen inside your nose, and are using a steroid spray regularly.
This trial studies whether daily smell training can improve smell loss caused by COVID-19. It may help people regain smell and possibly reduce related symptoms like distorted smells.
