Antineutrophil cytoplasmic autoantibodies (ANCA) were detected in patients
with autoimmune and vascular diseases such as Wegener's granulomatosis,
polyarteritis nodosa and systemic lupus erythematosus. Indirect
immunofluorescence (IIF) technique was employed to detect these autoantibodies.
By this method, two general patterns of ANCA were seen: a cytoplasmic (cANCA)
and a perinuclear form (p-ANCA). These antibodies were also observed
in rheumatoid arthritis (RA) but their prevalence and clinical significance have not
been determined. In this study the presence of ANCA in 52 RA patients (10 males
and 42 females) and its relationship with disease activity was evaluated. 26.9% of
patients were ANCA-positive, 36% of whom had c-ANCA and 64% a p-ANCA
pattern. The results also showed that there is no significant correlation between
ANCA titer and disease activity (p
