Seventy-two patients with rheumatoid arthritis (RA) and 18 with systemic lupus erythematosus (SLE) were typed for HLA class I and II antigens. No association was found with any of the antigens tested. However, B8 and DR3 were increased in patients with extra-articular features (EAF), while DR1 was increased in those with RA without EAF. In SLE a trend towards an increased frequency of DR7 was observed. DR5 was the negative marker in both diseases. Our results confirm the peculiar genetic characteristics in our population.
