Long‐term outcome and prognostic factors in enthesitis‐related arthritis: A case–control study

Abstract

In this study, patients with ERA had poorer physical outcomes compared with patients with oligoarticular or polyarticular JIA and controls from the general population. A family history of related diseases, sex, the presence of HLA-DRB1*08, the absence of HLA-DPB1*02, a persistently elevated ESR, early hip or ankle arthritis, and high numbers of affected joints were predictors of an unfavorable outcome.
