AbstractIn the diagnosis of Sjögren's syndrome the Salivary gland sonography (SGUS) has become established and can lead to a higher specificity of the applicable classification criteria. The OMERACT score is used to objectify the SGUS findings. In laboratory diagnostics, the subspecification of anti-SSA/Ro antibodies, but possibly also new biomarkers, are becoming increasingly important regarding diagnostic safety and the expected manifestations. When it comes to prevention, it has been shown that not only psychological stress, but also cardiovascular risk and the risk of lymphoma allow high-risk patients to be identified more precisely in the future. Using cluster analyses, various phenotype groups could be identified to which clinical parameters could be assigned. In 2020, therapy recommendations were published that are based on the clinical manifestations of SjS and recommend medications that are also used in the treatment of systemic lupus erythematosus (SLE) or rheumatoid arthritis. A particularly large number of therapeutic approaches are dedicated to the B cell: Rituximab and Belimumab have been included in the EULAR recommendations for serious manifestations and Ianalumab has a promising effect. Another focus of current research is the inhibition of co-stimulation between immune cells. After recent disappointing results for Abatacept, clinical trials show promising effects on Iscalimab and Dazodalibep.Thieme. All rights reserved.
