Abstract: Juvenile spondyloarthritis（JSpA）is an important group of articular rheumatism in children under 16 years old，which is associated with human leucocyte antigen B27. It is often misdiagnosed with its diverse clinical manifestations of less involvement of the axial skeletons but more hips and peripheral entheses in children than in adults. The rheumatism  associations international（ILAR） published the definition and classification standard（ILAR standard） of juvenile idiopathic arthritis（JIA） in 2004，which covered almost all childhood chronic arthritis. Among them，the sixth category enthesitis-related arthritis（ERA） contains part of JSpA，resulting in some cases of clinical confusion between JSpA and ERA，of which peripheral arthritis associated with attachment points and/or aponeurotic attachment point inflammation were both diagnosed as ERA. Due to this confusion，the international organization for trials in childhood rheumatism（PRINTO） developed the latest classification criteria in 2018，and proposed the classification criteria of ERA/SpA，to distinguish it from other subtypes of JIA. This article describes the latest diagnosis and treatment progress in ERA/SpA-related JIA，which aims to enhance clinicians’ understanding，diagnosis and treatment level of ERA/SpA related JIA and thus improve the prognosis.
