Sjogren's syndrome (SS) is an autoimmune disease chiefly affecting the exocrine glands. Manifestations of SS include salivary and lacrimal gland dysfunction. There is no generally accepted treatment for the underlying autoimmune reactivity or the exocrine gland dysfunction in SS. We propose to test the effects of etanercept therapy. In a randomized, double-masked, outpatient protocol, patients will receive etanercept for 2 times/week for 3 months. Therapy will be given by subcutaneous injection. Efficacy of treatment will be assessed by monitoring salivary and lacrimal function, serological markers of autoimmune activity, and subjective reports of local and systemic symptoms. The present trial will serve as a screening protocol to identify if etanercept should be further analyzed in a larger clinical trial for efficacy.
