Polyarthritis in adults with hypogammaglobulinaemia and its rapid response to immunoglobulin treatment.

Abstract

Five patients with primary hypogammaglobulinaemia developed a severe polyarthritis that had some features in common with rheumatoid arthritis. Their joint disease could be distinguished from rheumatoid arthritis, however, by the dramatic improvement after gammaglobulin treatment. The arthritis of hypogammaglobulinaemia can, therefore, be included among the few potentially curable polyarthritides.
