User:Mr. Ibrahem/Sjögren syndrome

Sjögren syndrome (SjS, SS) is a long-term autoimmune disease that affects the body's moisture-producing glands. Primary symptoms are a dry mouth and dry eyes. Other symptoms can include dry skin, vaginal dryness, a chronic cough, numbness in the arms and legs, feeling tired, muscle and joint pains, and thyroid problems. Those affected are also at an increased risk (5%) of lymphoma.

While the exact cause is unclear, it is believed to involve a combination of genetics and an environmental trigger such as exposure to a virus or bacteria. It can occur independently of other health problems (primary Sjögren syndrome) or as a result of another connective tissue disorder (secondary Sjögren syndrome). The inflammation that results progressively damages the glands. Diagnosis is by biopsy of moisture-producing glands and blood tests looking for specific antibodies. On biopsy there are typically lymphocytes within the glands.

Treatment is directed at the person's symptoms. For dry eyes artificial tears, medications to reduce inflammation, punctal plugs, or surgery to shut the tear ducts may be tried. For a dry mouth, chewing gum (preferably sugar-free), sipping water, or a saliva substitute may be used. In those with joint or muscle pain, ibuprofen may be used. Medications that can cause dryness, such as antihistamines, may also be stopped.

The disease was described in 1933 by Henrik Sjögren, after whom it is named; however, a number of earlier descriptions of people with the symptoms exist. Between 0.2% and 1.2% of the population are affected, with half having the primary form and half the secondary form. Females are affected about ten times as often as are males. Though the disease commonly begins in middle age, anyone can be affected. Among those without other autoimmune disorders, life expectancy is unchanged.
