Synovial fibroblasts in juvenile idiopathic arthritis: A scoping review

Semin Arthritis RheumPublished Scoping review

Authors' conclusion

All included studies identified mechanisms potentially linking synovial fibroblasts to specific disease traits in juvenile idiopathic arthritis.

Study context

Population
Peer-reviewed studies on synovial fibroblasts from patients with JIAeligible studies of 1778 screened
Participants
18 eligible studies
Outcome
Current knowledge on synovial fibroblasts in JIA
Methodological detailsMEDLINE, EMBASE and Web of Science, English-language peer-reviewed studies
  • MEDLINE, EMBASE and Web of Science
  • English-language peer-reviewed studies

Main finding

As reported in the abstract

  • Most studies identified synovial fibroblast subsets or functional characteristics that may be involved in disease pathogenesis
  • Mechanisms identified: cell-cell interaction with leukocytes, pro-inflammatory signaling and unfavorable connective tissue homeostasis that may contribute to cartilage damage or bony overgrowth
  • All included studies identified mechanisms potentially linking synovial fibroblasts to specific disease traits in JIA
  • Most findings similar to mechanisms described in synovial fibroblasts from adults with arthritis
