Primary Sjögren’s syndrome is a chronic systemic immune-mediated condition of unknown aetiology characterised by focal lymphocytic infiltration of exocrine (mainly salivary and lacrimal) glands. It affects 0.1-4.6% of the European population and 90% of cases are female. Although it usually presents in the fifth or sixth decade, it can be seen in younger people who tend to present with systemic disease and are less likely to have classical sicca symptoms. Patients should be referred to a rheumatologist to confirm diagnosis, and this may involve scintigraphy/sialography and/or labial gland biopsy.
