title: [Correlation study between lupus nephritis patients of rheumatism syndrome and SLEDAI--a clinical study].
abstract: OBJECTIVE
  To explore lupus nephritis (LN) patients' monocyte chemotactic protein 1 (MCP-1) and urinary IP-10 (ulP-10) levels, the correlation between each clinical activity index and rheumatism syndrome, thereby proving objective evidence for microscopic typing of rheumatism syndrome.
  
  
  METHODS
  Totally 60 LN patients were assigned to the rheumatism group (31 cases) and the non-rheumatism group (29 cases). Besides, 20 healthy volunteers were recruited as the normal control group. Clinical data and renal pathology were collected, and urinary levels of MCP-1 and IP-10 detected by ELISA. The correlation between rheumatism syndrome and each activity index as well as manifestations of clinical activities was comprehensively analyzed. Results (1) Patients in the rheumatism group were more liable to occur fever, serositis, edema, and hypertension (P<0.05). (2) Compared with the non-rheumatism group, patients in the rheumatism group exhibited much higher levels of 24 h protein quantification and blood urea nitrogen, higher levels of uMCP-1 and ulP-10. Microscopic hematuria, anti-ds-DNA, anti-Sm, the positive rate of AnuA, scores of SLEDAI and BILAG were higher in the rheumatism group than in the non-rheumatism group (P<0.05). Levels of plasma albumin and complement C3 were lower in the rheumatism group than in the non-rheumatism group (P<0.05). (3) The average activity index (AI) of the renal pathology was higher in the rheumatism group than in the non-rheumatism group. The most frequent pathological type of rheumatism group was type IV of LN.
  
  
  CONCLUSIONS
  More severe renal damage and immune abnormality occurred in LN patients of rheumatism syndrome. Rheumatism syndrome is closely correlated to clinical activity indices.
