What Is Sjögren’s Syndrome?
Sjögren’s syndrome is a systemic inflammatory autoimmune disease with a chronic, progressive course that primarily attacks the lacrimal glands of the eye and the salivary glands of the mouth, which are exocrine glands. Exocrine glands secrete the substances they produce through a duct.
Sjögren’s syndrome is ordinarily characterized by dysfunction of the lacrimal glands to produce tears causing dry eye and the salivary glands to produce saliva causing dry mouth, but is not limited by or to these features.
Besides involvement of these exocrine glands, there may be involvement of other parts of the body, termed extraglandular, which may be more severe than eye or mouth features.
There is not yet agreement on classifying Sjögren’s syndrome. Primary and secondary are the two forms generally accepted.1  Both forms can cause mild to severe disease, called the spectrum:
- Primary Sjögren syndrome. Disease occurs without involvement of other linked autoimmune disorders. In addition to the eyes and mouth, the nose, throat and skin may also be affected and joints, lungs, kidneys, blood vessels, digestive organs and nerves as well.2  Systemic manifestations (other than eyes and mouth) concern a third of patients, including lymphoma in 5% of the patients.3 
- Secondary Sjögren’s syndrome. Disease complicates other autoimmune disease such as systemic lupus erythematosus, rheumatoid arthritis, primary biliary cirrhosis, and celiac disease.
Diagnosis of Sjögren’s syndrome is made by most doctors based on Schimer’s test for tears and unstimulated whole salivary flow to assess objective eye and oral involvement, since these are the tests most physicians use in clinical practice.4  Specific antibody tests would be positive for anti-Ro (SSA)/anti-La (SSB) autoantibodies. Sjögren’s syndrome should also be considered when extraglandular manifestations such as vasculitis, polyneuropathy or arthritis occur, even when the patients do not complain of dry eyes and mouth.5 
There is no cure for Sjögren’s syndrome. Treatment is aimed to diminish symptoms. For example, steroids and Ibupropen are used to decrease inflammation and pain in joints. Artificial tears and ointments are used for dry eye.
Most people who develop Sjogren’s syndrome are older than 40 years. Nine of ten people with Sjögren’s syndrome are women.6
