RESUMO
Objective To evaluate the rationality of predisone dosage in the treatement of SLE with different clinical scoring systems. Methods The clinical data of 51 newly diagnosed patients with systemic lupus erythematosus(SLE) were collected, and disease activity was assessed by SLEDAI- 2000, BILAG- 2004 and SLAM-R scoring systems. The correlations between SLEDAI- 2000, BILAG- 2004 , SLAM-R scores and prednisone dosage were analyzed. Results BILAG-2004 score showed the best correlation with the dosage of prednision (r=0.827, P<0.001) .SLAM score showed the worst correlation with the dosage of prednision (r=0.512, P<0.001). Different treatment choice was associated with different organ/system involvement. Conclusions BILAG- 2004 , SLEDAI- 2000 and SLAM-R scoring systems all can be used as references for the prednisone dosage slection.It is suggested that the BILAG- 2004 scoring system is more reliable and comprehensive in clinical practice．
