Background. @entity1691 ( @entity1691 ) is a common @entity627 and is characterized by inflammation of the axial skeleton. @entity1530 is strongly associated with @entity1691 . Juvenile-onset @entity1691 (JAS) with disease onset before 16 years of age differs from @entity5427 ( @entity5427 ) in many respects. Objective. To compare the clinical features in JAS with different @entity4788 subtypes and analyze the differences between JAS and @entity5427 . Methods. 145 JAS and 360 @entity5427 @entity1 were included. The demographic data, clinical manifestations, laboratory markers, Bath @entity1691 indices, and @entity4788 subtypes were recorded. Results. @entity625 , @entity4932 , BASDAI, ESR, and CRP were significantly higher in JAS @entity1 with @entity1530 (*)2704 than those with @entity4788 -negative. Enthesitis and ESR were significantly higher in @entity1 with @entity1530 (*)2705 than those with @entity4788 -negative. The onset age of @entity1530 (*)2715 group was much earlier than the other groups. The @entity625 , @entity4932 , and hip joint involvement in JAS with @entity1530 (*)2704 were significantly higher than those in @entity5427 with @entity1530 (*)2704. Conclusion. JAS with different @entity4788 subtypes had similar features in most of manifestations; JAS and @entity5427 @entity1 with the same subtype could have distinctive courses. Early diagnosis, @entity572 , and control of @entity32 in JAS @entity1 will be helpful for improving the prognosis.
