[Variations in salivary immunoglobulins in Sjögren's syndrome (author's transl)].

A study of salivary immunoglobulins (IgA, IgG, IgM) was made in 74 subjects with or without Sjögren's syndrome. In the normal subjects, only IgA could be detected by classical immunodiffusion techniques. A correlation was sought between the presence of IgG and/or IgM in the saliva, and various clinical or objective clinical examinations, as well as with accessory salivary gland biopsy. This study indicates that in Sjögren's syndrome the detection of IgG and/or IgM is strongly correlated with sialography which is the surest examination used clinically. Thus the detection and estimation of salivary immunoglobulins is thus a simple and specific complementary examination in Sjögren's syndrome.
