ABSTRACT
Objective To explore the correlation of disease activity with the primary syndromes of deficiency and excess types of lupus nephritis(LN). Methods A retrospective study was carried out in 134 LN patients,and the LN patients were differentiated into deficiency syndrome(deficiency group)and excess syndrome(excess group). The disease activity related indicators of systemic lupus erythematosus disease activity index(SLEDAI)scores, complements, inflammation indexes, and urine indicators were compared between the two groups. Results Of the 134 LN patients,33 cases were differentiated into excess syndrome,and 101 cases were differentiated into deficiency syndrome. According to the SLEDAI scores, 9.09％ of the patients in excess group were inactive, 4.95％ of the patients in deficiency group were inactive, and most of the patients in the two groups were at severe active stage. There was no significant difference of SLEDAI scores between the two groups(P>0.05) . The differences of complement C3 and C4 , inflammation indexes of C-reactive protein(CRP)and erythrocyte sedimentation rate(ESR),urine protein,and urine occult blood were also insignificant between the two groups (P>0.05). Conclusion There is no correlation between deficiency-excess syndrome differentiation and disease activity of LN. Most of the LN patients with deficiency syndrome are at active stage,but not at remission stage.
