[Gougerot-Sjögren syndrome. Diagnostic criteria and therapeutic methods]

CLASSIFICATION CRITERIA: Several systems of classification criteria have been developed for Sjögren's syndrome. These systems allow patient classification but do not constitute diagnostic criteria. The most widely used is based on the Fox criteria which are totally specific but have low sensitivity. The European criteria have satisfactory sensitivity and specificity.

In all cases, the elements comprising the sicca syndrome must be identified. A labial biopsy for histology of the accessory salivary glands may be helpful. A less extensive search is sometimes sufficient if the aim is uniquely diagnostic. TREATMENT OF SJOGREN'S SYNDROME: Symptomatic treatment of the sicca syndrome with local procedures is aimed at reducing the functional disorder. The systemic route is used to treat the dysimmune component. As in most connective tissue diseases, most patients can be stabilized, limiting the functional consequences of the disease, but cure remains illusive.
