Identification of definitive serum biomarkers associated with disease activity in primary Sjögren's syndrome

In this study, we sought to identify definitive biomarkers associated with disease activity in primary Sjögren's syndrome (pSS). Serum protein concentrations in pSS patients and healthy controls (HCs) were comprehensively screened using high-throughput proteomic analysis, and differentially expressed proteins were extracted. Correlation between differentially expressed proteins and European League Against Rheumatism Sjögren's Syndrome Disease Activity Index (ESSDAI) scores was analyzed and disease activity-associated biomarkers were identified. These biomarkers were validated by enzyme-linked... Mehr ...
