Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Background: Uveitis is inflammation inside of the eye. It can cause vision loss. Little is known about the disease. There are few treatment options. Researchers want to learn how the bacteria in the gut might affect how people with uveitis respond to treatment. Objective: To investigate the natural bacteria present in the gut and intestines to study whether it might affect uveitis treatment. Eligibility: People ages 13 and older with non-infectious uveitis who are enrolled in the ADalimumab Vs. conventional ImmunoSupprEssion for uveitis (ADVISE) trial, and their uveitis is being treated or will be treated with an oral corticosteroid, conventional immunosuppressive drugs, or adalimumab. Design: Participants will have 2 study visits at their respective clinical sites. The visits will be 6 months apart. The visits will align with the main ADVISE trial visits. Participants will give blood samples. A needle will be used to take blood from an arm vein. They will also give stool samples. They will get stool collection kits. They will collect each sample at home and send it to the NIH. Participants will complete online diet history questionnaires. They will get an ID and password to access the questionnaires. The ID is a unique code. This means it does not contain any personal identifiers. They can complete the questionnaires at home. Participation in this study will last for 6 months.
