A current perspective on Sjögren's syndrome.

Sjögren's syndrome is a common autoimmune disorder characterized by dry mouth and dry eyes. Symptoms and signs are chronic and can be severe. The diagnosis of Sjögren's syndrome can be confusing and time-consuming. The management can also be a significant challenge for the clinicians. However, recent genomic and proteomic developments are unlocking the mystery of the disease process as well as contributing to our ability to define, diagnose, and develop new treatment modalities for patients with this complex disorder.
