title: Coexistence of HLA-B27 ankylosing spondylitis and DR4 seropositive nodular rheumatoid arthritis in patient with membranous nephropathy.
abstract: A case of definite ankylosing spondylitis (AS), classical rheumatoid arthritis (RA) and membranous nephropathy is presented. Concurrent presence of the HLA-B27 and HLA-DR4 antigens was demonstrated. The association of AS and RA as well as RA and membranous nephropathy are discussed and the literature reviewed.
