To the editor: Esdaile, Dwosh, Urowitz, Smythe, and Falk (1) have reported in this journal a similar frequency of HLA B27 in patients with seronegative rheumatiod arthritis and a control population. They infer that this is discrepant with our findings of HLA B27 in 22 and 73 patients with seronegative rheumatoid arthritis (2) but fail to comment on our predominantly male group of patients with B27, frequent subcalcaneal erosions, and absence of symmetrical upper limb joint involvement. An indistinguishable group of patients, small in number, where disorders are labelled "incomplete Reiter's syndrome," is separately considered in the Toronto group's report
