One year in review 2021: Sjogren's syndrome

Sjogren's syndrome (SS) is a multifactorial systemic autoimmune disease of unknown aetiology characterised by a wide spectrum of different clinical manifestations and scattered complications. Recently, great efforts have been made to elucidate mechanisms involved in the pathogenesis of the disease in order to identify exploitable therapeutic targets in SS. Similarly, novel insights have enabled to better define disease phenotypes and different outcomes. Ultimately, the discovery of new potential therapeutic targets and a better stratification of patients are paving new avenues for novel treatment options and treat-to-target therapeutic approach. In this review, we will provide a critical digest of the recent literature published in 2020 on SS pathogenesis, clinical manifestations and novel treatment options.
