Actualités dans le syndrome de Sjögren primitif : aspects cliniques et thérapeutiques

Sjogren's syndrome (SS) is a systemic orphan disease. It is characterized by the involvement of epithelial tissues leading to the term of autoimmune epithelitis. New classification criteria have been developed in 2016. New scores have also been developed: a patient-reported outcome called ESSPRI and a score assessing systemic activity of the disease called ESSDAI. These new tools are very helpful to better stratify patients and to customize the management of this very heterogeneous disease. Among the autoimmune diseases, SS is associated with the highest risk of lymphoma. Five to ten percent of the patients will have a B cell lymphoma mostly a low-grade lymphoma developing from mucosa-associated lymphoid tissue (MALT). Major advances have been made in this field: pathogeny is better understood, new predictors are available and progresses have been made in the management of this severe complication. Research in the field of SS is very dynamic as illustrated by the high number of therapeutic trials. There is hope that these innovations, reviewed in the present article, will have potential significant repercussions for the patients in the next few years.
