What researchers measure

Primary outcomes

  1. The remission rate of SLE response index at month 12 of treatment

    Use SRI-4 to represent the response index, with a higher response rate indicating better drug efficacy

    Time frame: months 12

  2. Improvement in platelet count

    Platelet count at month of treatment,Increased platelet count indicates improvement in disease

    Time frame: months 12

Secondary outcomes

  1. Percentage of patients with a decrease of ≥ 4 points in the SELENA-SLEDAI score from baseline at months 6 and 12

    A decrease of ≥ 4 points from baseline in the SELENA-SLEDAI score indicates a good drug response effect

    Time frame: months 6 and 12

  2. Hormone reduction

    Changes in patient hormone dose from baseline at month 12,reduced hormone dosage indicates improvement in disease

    Time frame: month 12

  3. B lymphocyte count

    Changes in patient B lymphocyte count from baseline at month 12

    Time frame: month 12
