title: Effect of penicillamine treatment on immune complexes in two cases of seropositive juvenile rheumatoid arthritis.
abstract: A correlation has previously been observed between the presence of enhancing complexes and cutaneous vasculitis in rheumatoid arthritis. Two parients with seropositive juvenile rheumatoid arthritis are described in whom enhancing complexes were detected before the appearance of cutaneous vasculitis. Their contrasting response to penicillamine is discussed in relation to the role of of rheumatoid factor and antinuclear antibodies.
