Sjögren's Syndrome is diagnosed using Rheumatoid factor (RF) and anti-CCP antibodies, ANA, anti-dsDNA, complement (C3/C4) for lupus, ESR and CRP and targeted clinical evaluation. Sjögren's syndrome is an autoimmune disease primarily affecting the salivary and lacrimal glands, causing dry eyes (xerophthalmia) and dry mouth (xerostomia). It can be primary or secondary to other autoimmune diseases like RA or lupus.
Clinical Context
The diagnostic process for Sjögren's Syndrome begins with Inflammatory markers and targeted autoantibody panel; joint imaging; specialist rheumatology review for diagnostic uncertainty. Key investigations include Rheumatoid factor (RF) and anti-CCP antibodies, ANA, anti-dsDNA, complement (C3/C4) for lupus, ESR and CRP, Plain X-ray of affected joints. The gold standard is: ACR/EULAR classification criteria; synovial biopsy or polarised microscopy (crystal arthropathies); MRI sacroiliitis for axial spondyloarthritis. Clinical guidelines from ACR / EULAR / BSR / NICE define the diagnostic criteria and recommended investigation pathway.
