[Diagnostic criteria for Sjögren's syndrome]

Sjödgrens syndrome is a common autoimmune disease with highly variable clinical manifestations, making diagnosis difficult and sometimes delayed. Its specific clinical presentation combines oral and ocular dryness, asthenia and joint involvement. However, visceral involvement and potentially severe complications, including lymphoma, are frequently observed. These can be indicative of the disease and should lead to consider Sjögren's syndrome as a diagnosis. Internationally agreed upon diagnostic criteria were developed to improve the ability to make a definitive diagnosis, in order to provide follow-up and appropriate treatment measures as early as possible. These criteria, which include clinical, laboratory and histological measures, are easy to use in the daily practice, and make it possible to rule out the extensive differential diagnosis of sicca syndrome.
