Box 5800, 6202 AZ Maastricht, the Netherlands; e-mail: wwe{at}sane.azm.nl Reflex sympathetic dystrophy (RSD) is a relatively common disabling disorder of unknown pathophysiology. From a cohort of 52 patients, carefully selected to fulfill the recently formulated diagnostic criteria for RSD, venous blood samples were taken for typing of class I and II major histocompatibility antigens. The frequency of HLA-DQ1 was found to be significantly increased compared with control frequencies. The association provides an indication for an organic basis of RSD.
