Brief summary
Treating severe thrombocytopenia is a challenge in the management of systemic lupus erythematosus. Although rheumatologists have followed some rules in real practice,there is very few evidence to support the current treatment algorithm. The purpose of this study is to compare the complete remission rate and partial remission rate of cyclophosphamide and hydroxychloroquine for treating severe thrombocytopenia in Chinese SLE patients.
Detailed description
This is a prospective,randomized,open-label,multi-center clinical trial. The aim of this study is to test the efficacy of GC(gluco-corticosteroid)+HCQ(hydroxychloroquine) and GC(glucocorticosteroid)+CTX(cyclophosphamide) with sequential AZA(azathioprine) in the induction and maintenance therapy of severe thrombocytopenia in SLE patients.
Interventions
Hydroxychloroquine 200 mg BID for 12 months
Cyclophosphamide 1000mg intravenous infusion every month for 6 months
After Cyclophosphamide treatment, Azathioprine 100mg once daily for 6 months
Methylprednisolone 40-50 mg once daily for 1 months and then taped for 12 months
