Sjogren syndrome

Sjogren syndrome is a chronic inflammatory and autoimmune disorder characterized by diminished lacrimal and salivary gland secretion (sicca complex).

May present with fatigue and dry eyes (keratoconjunctivitis sicca) and dry mouth (xerostomia).

Diagnosed by positive antinuclear antibodies, anti-60 kD (SS-A) Ro and anti-La autoantibodies, decreased saliva and tear production, lymphocytic infiltration in labial salivary gland biopsy.

Treatment is mainly symptomatic.

Sjogren syndrome is a systemic autoimmune disorder, characterized by the presence of dry eyes (keratoconjunctivitis sicca) and dry mouth (xerostomia) as a consequence of lymphocytic infiltration into the lacrimal and salivary glands.[1]Nocturne G, Mariette X.

Additional symptoms can include dryness of skin, nose, throat, vagina; arthralgias and myalgias; peripheral neuropathies; pulmonary, thyroid, and renal disorders; and lymphoma.[2]Fox PC.

Sjogren syndrome can occur alone (primary Sjogren syndrome) or be associated with another autoimmune disease (secondary Sjogren syndrome) such as lupus, rheumatoid arthritis, and systemic sclerosis.[3]Anaya JM, Tobon GJ, Vega P, et al.
