HLA-B27 Antigen in Diagnosis of Atypical Seronegative Inflammatory Arthropathy
Overview
Affiliations
Eighteen patients with an inflammatory pauciarticular peripheral arthropathy not typical of any known entity showed an asymmetrical pattern of disease, with a predilection for the lower extremities. Destructive joint changes and deformities were absent (mean follow-up 10 years). Although spondylitis and sacroiliitis were absent on x-rays, HLA-B27 antigen was found in 8 patients (44%). This antigen and similar joint symptoms are also found in other forms of arthritis.
