Longitudinal associations of flare and damage accrual in patients with systemic lupus erythematosus

Lupus Sci MedPublished Prospective cohort study

Authors' conclusion

Flares independently increased the risk of damage accrual.

Study context

Population
Patients with systemic lupus erythematosus (SLE) in the Asia Pacific Lupus Collaboration cohort with ≥3 years of prospectively captured datamedian follow-up 5.7 years
Participants
1,556 patients
Exposure
Flares vs no flares
Outcome
Damage accrual (SLICC/ACR DI, assessed annually)
Methodological detailsmultivariable, multifailure survival analyses
