ABSTRACT
Objective To explore the correlation of anticardiolipin antibody (ACL) and lupus nephritis (LN) glomerular microthrombi (GMT) in patients with systemic lupus erythematosus (SLE) and to analyze their clinical manifestations and renal pathological characteristics.Methods The clinical data of 126 LN patients treated at our hospital between January 2005 and October 2010 were retrospectively reviewed.The factors,including age,gender,the clinical manifestations in and outside of kidney were evaluated by multivariate Logistic regression analysis.Enzyme-linked immunosorbent assay (ELISA) was used to test the serum levels of ACL in all patients.Statistical analysis was conducted using x2 test and Logistic regression.Results ① All 126 patients were investigated.Thirty-eight LN patients had GMT.When compared with the LN-non-GMT group,the SLE disease activity index (SLEDAI),urinary protein quantity (24 h),serum creatinine,serum urea nitrogen,anti-dsDNA antibody (+),the incidence of severe hypertension,anemia,thrombocytopenia,arthritis were higher in the LN-GMT group (P<0.01).Logistic regression analysis showed that SLEDAI (OR=2.486,95%CI 1.678-3.684,P=0.000),anemia (OR=4.628,95%CI 1.045~20.496,P=0.044) were correlated with GMT; ② The pathologic results of renal biopsy showed that GMT had an incidence of 30.2% (n=38) in LN.As compared with the LN-non-GMT group,Wilcoxon test showed that the LN-GMT group suffered more severe greater renal pathological injuries (P=0.012).The pathological types of LN-non-GMT and LN-GMT groups were as follows:type Ⅳ (38% vs 76%) and type Ⅲ (31% vs 8%); ③ The positive rate of ACL was higher in the LN-GMT group than that in the LN-non-GMT group (n=23,61% vs n=15,36%).The differences were statistically significant (P=0.018).Conclusion GMT is not rare in LN.SLEDAI,anemia and positive ACL are correlated with GMT,LN patients with concurrent GMT have more severe renal pathological changes.
