Sera from 50 patients with various stages of ankylosing spondylitis were tested for the presence of antinuclear antibodies (ANA), anti-DNA antibodies, rheumatoid factor and antistreptolysin. Antinuclear antibodies (immunofluorescent technique) were detected in the sera of 10 patients (20%), associated in one case with anti-DNA antibodies (immunofluorescent technique). The disease activity in ANA-positive cases was low to moderate.
