[Sjögren's syndrome].

A case of a woman who complained of dryness of the mouth, eyes and lack of tears is presented. For the diagnosis traditional tests were used--Schirmer's test, gastric intubation, as well as modern immunologic methods--immunoglobulins of single-chain and natural anti-DNA antibodies, radioscintigraphy of the salivary glands. The positive Schirmer's test, the slow gastric secretion with normal secretion at the lower normal range, the positive natural and anti DNA antibodies with increased IgA, IgG, IgM, and the data of the radioscintigraphy of the salivary glands make an early diagnosis possible and facilitate a timely modern treatment.
