Clinical Report: Effects of Prolonged High Disease Activity on Damage Accumulation

Overview

This study investigates the impact of cumulative high disease activity on damage accrual in pediatric systemic lupus erythematosus (cSLE).

Background

Childhood-onset systemic lupus erythematosus (cSLE) presents unique challenges, often leading to more severe clinical manifestations and a higher risk of long-term organ damage compared to adult-onset SLE. This study aims to fill gaps in the literature regarding the effects of prolonged high disease activity in cSLE patients.

Data Highlights

Key Findings

• 64.3% of cSLE patients experienced high disease activity status (HDAS).
• Patients with HDAS had a significantly higher rate of damage accrual (33.3% vs. 11.4%, p < 0.001).
• Time-adjusted cumulative HDAS (cHDAS) was significantly higher in patients with damage.
• Increasing thresholds of time-adjusted cHDAS correlated with higher risk of damage accrual (hazard ratios from 6.2 to 16.1).
• Neuropsychiatric involvement and cHDAS ≥5% were independent predictors of damage accrual.

Clinical Implications

The findings highlight the association between cumulative high disease activity in cSLE patients and long-term organ damage.

Conclusion

The study highlights the association between prolonged high disease activity and damage accrual in pediatric SLE.
