Washed gut bacteria transplant for allergic rhinitis
Treatments studied
Part of Ear, nose & throat, Immune system & allergy, Lungs & breathing clinical trials.
This trial tests a treatment called washed microbiota transplantation, which transfers gut bacteria from healthy donors to people with allergic rhinitis. The goal is to see if changing the gut bacteria can reduce allergy symptoms like sneezing, itching, and a runny or blocked nose.

This trial is studying the bacteria in your nose and mouth during treatment with an allergy spray placed under your tongue. The goal is to understand how this treatment affects your allergy symptoms and your body's natural defenses.
This study uses a small microneedle patch to collect skin-related samples to help predict how well allergy immunotherapy may work. It includes people with house dust mite allergy and also a healthy control group, so researchers can compare biomarker results.
This trial tests whether transplanting specially washed gut bacteria from healthy donors can reduce nasal allergy symptoms like congestion, runny nose, itching, and sneezing. The transplant is given through a tube into the stomach or intestines, and could be a new way to treat chronic rhinitis.
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 4-week treatment of electroacupuncture combined with microneedle knife for people with moderate to severe allergic rhinitis. It may help reduce symptoms without relying on standard allergy medications.
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.
