[Sjögren's syndrom: clinical, diagnostic and therapeutic innovations].

Sjögren's syndrome (SS) is a systemic autoimmune disease affecting the lacrimal and salivary glands. In up to one third of patients, SS may be complicated by potentially severe extra-glandular visceral involvement, which can be life-threatening. Diagnosis is often difficult based on a combination of clinical and biological evidence. The development of new imaging techniques can now help the clinician in his diagnostic approach. Long considered incurable, new medical and surgical treatments are being studied and are potentially promising. Paramedical management and regular physical activity are also essential and contribute to the improvement of patients' fatigue. The objective of this article is to review the main clinical manifestations as well as the diagnostic and therapeutic novelties developed in recent years.
