Authors' conclusion

GAS6 is an independent predictor of nephritis in patients with SSc. However, there is no association between GAS6 and nephritis in juvenile patients with SLE.

Study context

Population
Adults with systemic sclerosis (SSc) and children with systemic lupus Erythematosus (SLE)
Participants
60 vs 40
Comparison
Serum GAS6 in patients with vs without nephritis
  • SScn = 60
  • SLEn = 40
