Title: Serum anti-SS-B/La and IgA rheumatoid factor are markers of salivary gland disease activity in primary Sjögren's syndrome. Author: Atkinson JC, Travis WD, Slocum L, Ebbs WL, Fox PC. Journal: Arthritis Rheum; 1992 Nov; 35(11):1368-72. PubMed ID: 1445455. Abstract: OBJECTIVE: To identify serologic markers of salivary gland disease activity in 43 patients with primary Sjögren's syndrome. METHODS: Comparison of salivary gland biopsies (focus scores) and flow rates with serum concentrations of IgA and IgM rheumatoid factor (RF), total serum IgG, serum anti-SS-B/La antibodies, and the erythrocyte sedimentation rate. RESULTS: Serum anti-SS-B/La antibody levels correlated with focus scores (rs = 0.477, P < 0.0025). Serum IgA-RF concentrations correlated inversely with stimulated parotid gland salivary flow rates (rs = -0.394, P < 0.01). CONCLUSION: Measuring serum levels of anti-SS-B/La and IgA-RF would be useful when monitoring salivary responses in therapeutic trials, especially in patients with minimal salivary function.[Abstract] [Full Text] [Related] [New Search]
