Correlations between Raynaud’s phenomenon, vasculitis, and immunological features in patients with primary Sjögren’s syndrome
| Primary SS with Raynaud’s phenomenon (n=19) | Primary SS without Raynaud’s phenomenon (n=31) | p Value2-150 | Primary SS with vasculitis (n=13) | Primary SS without vasculitis (n=37) | p Value2-150 | |
| AECA level (mean (SD) OD) | 0.55 (0.21) | 0.37 (0.17) | <0.01 | 0.47 (0.25) | 0.42 (0.19) | NS |
| Cryoglobulinaemia | 3 | 6 | NS | 6 | 3 | <0.01 |
| Antinuclear antibodies | 11 | 20 | NS | 10 | 21 | NS |
| Anti-SS-A antibodies | 8 | 15 | NS | 11 | 12 | <0.01 |
| Anti-SS-B antibodies | 7 | 12 | NS | 10 | 9 | <0.01 |
↵2-150 The Mann-Whitney U test was used for comparison of AECA levels. The χ2 test with Yates’s correction was used for the other parameters. OD : optical density; SS : Sjögren’s syndrome.
