Sjogren's syndrome is a chronic inflammatory disease of unknown aethiology. It is characterized by decreased secretion of salivary and lacrimal glands, which induces keratoconjunctivitis sicca and xerostomia. Sjogren's syndrome is a central autoimmune disease, and it has characteristics of both organ-specific and generalized autoimmune diseases. It can exist as a primary disease or is associated with other autoimmune diseases (most freyuently with systemic lupus erythematosus or rheumatoid arthritis) and is classified as a secondary Sjogren's syndrome. The aethiology is multifactorial, and it has not yet been completely explained. In the pathogenesis of the disease the important role have genetic predisposition, chronic oestrogen stimulation, end viral infections, especially of the herpes virus group (EBV, CMV, HHV6) and retroviruses. In the clinical picture xerostomia, xerophtalmia and non-erosive arthritis are the most common features, with the whole spectrum of extraglandular manifestations of respiratory, gastrointestinal, skin, and haematologic, neurologic and endocrinologic disturbances. Pathohistological findings of minor labial salivary gland lymphocyte infiltration is the most specific and the most sensitive diagnostic criterion of Sjogren's syndrome. The diagnosis of keratoconjunctivitis sicca is made by Schrimer's test, Rose bengal dye staining and by the "tear break up time". Differential diagnosis of Sjogren's syndrome includes an extremely large number of various pathologic states. The treatment of Sjogren's syndrome consists of symptomatic treatment of dry mucosas (artificial tears, etc.) and also of antiinflammatory drugs, glucocorticoids, immunosuppressive drugs. Plasmapheresis and intravenous administration of immunoglobulins are used for immunosuppression in these patients.

Sjogren's syndrome is a chronic progressive autoimmune disorder manifested predominately by xerostomia (dry mouth) and keratoconjunctivitis sicca (dry eyes). It can also affect many body systems. Up to 5% of people over the age of 60 years have primary Sjogren's syndrome, and approximately one third of patients present with extraglandular (systemic) manifestations. This disease is seen mostly in middle-aged women, with a small but significant proportion of these women developing lymphoid neoplasia. The exact etiology is still unknown. This autoimmune disorder is characterized by B-cell activation, the production of numerous auto-antibodies, and the loss of immune tolerance. Salivary gland biopsy remains the most helpful diagnostic test. Treatment is aimed at moisture replacement, which alleviates the discomfort and slows the destructive process. Because of its prevalence in older women, the obstetrician-gynecologist must be aware of the diagnostic and therapeutic approach to Sjogren's syndrome.
