Objective: To observe the effect of Cordyceps sinensis and artemisinin in preventing recurrence of lupus nephritis (LN).
Methods: Sixty-one LN patients, who had no activities by corticosterone and cyclophosphamide (CTX) impacting therapy were randomly divided into two groups. The 31 cases in the treated group were given Cordyceps powder 2-4 g/d before meal and artemisinin 0.6 g/d after meal in three portions orally taken for 3 years. The 30 patients in the control group were treated with tripterygiitotorum and/or Baoshenkang tablet. The consecutive observation lasted for 5 years to monitor the clinical manifestations of lupus and laboratory indexes including blood creatinine, creatinine clearance rate (CCr) and antinuclear antibodies (ANA).
Results: The therapeutic effect showed markedly effective in 26 cases (83.9%), effective in 4 (12.9%) and ineffective in 1 (3.2%) in the treated group, while in the control group, the corresponding numbers were 15 (50.0%), 8 (26.7%) and 7 (23.3%), the difference between the two groups in markedly effective rate was significant (P < 0.01). In the treated group, C3 level was stabilized at above 1.21 +/- 0.20 g/L, which was over the normal range, CCr was unchanged as compared before and after treatment, which was significantly different from that in the control group. Moreover, the side-effects occurred in the treated group was less.
Conclusion: Cordyceps and artemisinin could prevent the recurrence of LN and protect kidney function.
