Abstract
Serum from 91 patients with Sjögren's syndrome (SS) was examined for antiperinuclear factor (APF). Nine out of 29 patients with SS alone (31.0%) were positive as opposed to 27 out of 40 with SS + rheumatoid arthritis (67.5%) and to 3 out of 22 with SS + other autoimmune disorders (13.6%). A clear relationship was established between APF and agglutinating or non-agglutinating rheumatoid factor.
