title: Seronegative pauciarticular arthritis and HLA B27.
abstract: Twenty-six patients with a pauciarticular arthritis have been studied clinically, radiologically and with histocompatibility typing. An increased frequency of HLA B27 was found (p = 1.87 x 10(-12)). Low back and buttock pain, Achilles tendinitis and dactylitis of the toes were more frequent in HLA-B27 positive patients. It is suggested that histocompatibility testing may be of some value in diagnosis and in the investigation of the possible 'reactive' nature of this type of arthritis.
