Efficacy of Individualized Rituximab in Maintaining Remission of Moderate and Severe Systemic Lupus Erythematosus

Several clinical studies have shown that rituximab is safe and effective for the induction of remission in moderate to severe systemic lupus erythematosus, and has been recommended by several guidelines for the induction of remission in refractory lupus with important organ involvement. However, there are few studies on the use of rituximab in the long-term maintenance and remission of the disease. There is no recognized scheme for the dose, interval and course of treatment of the drug. In this study, patients with moderate and severe systemic lupus erythematosus who achieved remission after standardized treatment were randomly divided into two groups at 1:1 and followed up every 3 months for 24 months. The basic situation and disease activity score of each subject were recorded. The recurrence rate of each observation group was calculated, the influencing factors of disease recurrence were analyzed, and a more reasonable drug use scheme was explored.
