Immune Responses to Antigens in Non-Infectious Eye Inflammatory Diseases - Full Text View

ClinicalTrials.gov Identifier:	NCT00357071

Purpose

This study will collect blood samples from patients with non-infectious eye inflammatory diseases-a spectrum of eye disorders that can produce sight-threatening vision loss. The blood will be analyzed for substances that may provide a better understanding of the nature of these disorders, possibly leading to improved treatments. Treatment is not offered under this protocol.

Patients 6 years of age and older with an eye inflammatory disease, including non-infectious uveitis, ocular cicatricial pemphigoid, non-infectious scleritis, episcleritis, Stevens Johnson syndrome, Moorens ulcer, peripheral ulcerative keratitis and keratoconjunctivitis sicca, may be eligible for this study. Patients may or may not currently be participating in a treatment trial.

Participants will have blood drawn through a needle in an arm vein. More samples may be collected if patients enrolled in another study are scheduled for additional visits. No more than 4 teaspoonfuls of blood will be collected at any one time.

Detailed Description:

Ocular inflammatory diseases can lead to visual loss in adults as well as in children. These conditions are usually characterized by repeated exacerbations and remissions. The underlying cause of majority of these conditions is not clear even though an autoimmune mechanism has been implicated.

Various studies have reported an altered immunological profile in these patients. An underlying immune mechanism has been thought to be playing a role in at least some of the ocular inflammatory diseases.

This protocol proposes to test for proliferative cell mediated and humoral responses against self-antigens from patients with ocular inflammatory diseases. Patients will be recruited from other ongoing protocols. An attempt would be made to find any correlation between the clinical disease and the immunological findings. These findings will not be used for diagnostic nor therapeutic purposes.
