Open Access Abstract The aim of the present study was to investigate the effect of long-term infliximab treatment on various autoantibodies in patients with rheumatoid arthritis. Serum samples from 30 consecutive patients who were prospectively followed during infliximab and methotrexate therapy for refractory rheumatoid arthritis were tested at baseline and after 30 54 and 78 weeks. At these points median values of the Disease Activity Score were interquartile range and respectively. Various autoantibodies were assessed by standard indirect immunofluorescence and or ELISA. Initially 50 of patients were positive for antinuclear antibodies and this figure increased to 80 after 78 weeks P . A less marked similar increase was found for IgG and IgM anticardiolipin antibody titre whereas the frequency of anti-double-stranded DNA antibodies by ELISA exhibited a transient rise up to at 54 weeks and dropped to 0 at 78 weeks.
