Prediction of Relapse Risk in Stable Systemic Lupus Erythematosus

• Status: Unknown status
• Trial end date: 2020-06-01
• Target enrollment: 0
• Participant gender: All

Summary

Whether and when systemic lupus erythematosus (SLE) patients with stable disease should withdraw glucocorticoid (GC)? How about the relapse risk? What are the risk factors for disease flare? All the above are unclear. Long-course GC treatment has a lot of side-effects even in a sustaining low dose. The aim of this study is to explore the relapse risk after GC withdrawal in SLE patients with stable disease more than one year and to establish a predictive model for flare risk stratification.
