Abstract

Sjogren’s syndrome (SS) is a non-hereditary and relatively common disease  with adult onset. It is characterized by extreme tiredness, diminished  exocrine  glandular function, specific auto-antibody production and focal infiltration of B and T lymphocytes. The disease may be also complicated by malignant lymphoma. Most SS patients have high serum levels of anti-nuclear antibodies (ANA), and the ANA subtypes SS-A and SS-B (autoantibodies to RNA-modifying spliceosome components) are used as diagnostic markers of SS. Antibodies to chromatin make  cancer  cells more  sensitive  to DNA-binding  cytostatic drugs  suggests that  indeed  the  ANA in SS may  have  some  influence on  cellular functions, and  perhaps contribute to SS patients’ symptoms.

A most recent  report from our department has demonstrated that  ANA including SS-A and SS-B are present at high titres in sera obtained from SS patients many years before the onset  of symptoms, and even longer times before the diagnosis was established.
