Objective To determine the feasibility and risk of flares by achieving successful glucocorticoid (GC) tapering during the first year of juvenile SLE and the value of early achievement of childhood lupus low disease activity state (cLLDAS).Methods The medical charts of children with moderate-to-severe SLE between 2012 and 2022 were retrospectively analysed. Successful tapering was defined as the employment of a prednisolone equivalent dose, lower dose of either ≤7.5 mg/day or ≤0.15 mg/kg/day, as per the cLLDAS definition. A linear mixed-effects model was used to determine the fixed effects affecting the GC dose over the first year. Cox regression analysis was used to identify whether successful tapering increased the risk of flares, and logistic regression was used to determine the odds of flares after the twelfth month of treatment.Results Successful GC tapering was observed in 50 out of 80 patients (62.5%) within the first year of treatment, and flares were observed in 23 (28.8%) patients. The GC tapering trajectories over time were similar based on flare observations (p>0.05). Furthermore, successful tapering did not increase the risk of flares. Additionally, patients without flares received significantly higher GC doses as the initial treatment (p=0.046). Achievement of cLLDAS was observed in 40 (50%) patients at the twelfth month; however, achievement was not protective against future flares, and positive anti-double-stranded DNA antibodies at the twelfth month increased the odds of flares (OR: 4.8, p=0.008).Conclusion Successful GC tapering is feasible and does not increase the risk of flares during the early disease phase. However, flares are common and adversely affect GC tapering. Thus, the identification of children with an increased risk of flares on GC tapering is needed to reduce the GC burden.
