Serum bile salt-stimulated lipase levels associates with systemic inflammation and declines with effect of treatment in juvenile idiopathic arthritis

Pediatr Rheumatol Online JPublished Cross-sectional study

Authors' conclusion

Serum BSSL tracks systemic inflammatory activity and decreases with clinical improvement in JIA

Study context

Population
Children with juvenile idiopathic arthritis (JIA) and healthy controls
Exposure
Children with JIA vs healthy controls
Outcome
Serum BSSL concentrations
Methodological detailscase-control comparison with healthy controls, longitudinal follow-up after treatment
  • Case-control comparison with healthy controls
  • Longitudinal follow-up after treatment

Main finding

As reported in the abstract

Serum BSSL concentration
  • Significantly higher serum bile salt-stimulated lipase (BSSL) concentrations in children with JIA than in healthy controls
  • BSSL levels decreased following medical treatment

Observational data: associations, not effects.

Further findings

Correlations of BSSL with inflammatory markers and disease activity

BSSL correlated positively with platelets, ESR and S100A8/A9
No correlation with JADAS27
