Washed gut bacteria transplant for nasal allergy symptoms
Treatments studied
Part of Ear, nose & throat, Immune system & allergy, Infections, Lungs & breathing clinical trials.
This trial tests whether washing and transplanting healthy gut bacteria can help relieve nasal allergy symptoms. It is for people with ongoing stuffy, runny, or itchy nose who haven't taken certain stomach or antibiotic medicines recently.

This trial tests if a special type of fecal transplant (called washed microbiota transplantation) can help calm the immune system and reduce allergy symptoms. If you have moderate-to-severe allergic rhinitis and are otherwise healthy, this treatment might offer a new way to find relief.
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.
This trial tests a treatment called washed microbiota transplantation for people with food intolerance. It may help reduce symptoms by restoring healthy gut bacteria.
This trial tests whether transplanting specially cleaned gut bacteria from healthy donors can help children with ADHD. It aims to see if improving the balance of gut bacteria can reduce ADHD symptoms.
This trial tests if washed microbiota transplantation (WMT) can help solid organ transplant recipients who develop gut symptoms, infections, or rejection after their transplant. WMT may restore a healthy balance of gut bacteria to improve these problems.
This trial tests if transplanting healthy nasal bacteria from a donor can help people with chronic sinusitis. It aims to restore a healthy microbiome in the nose to reduce symptoms like congestion and discharge.
