title: Distribution of HLA-B27 in patients with juvenile rheumatoid arthritis.
abstract: HLA antigens were examined in 27 patients with juvenile rheumatoid arthritis. HLA-B27 was found in none. The result was different from most other previously reported studies. The most likely explanation for this difference is the possibility that some patients with juvenile ankylosing spondylitis may have been included among the patients in the other studies.
