Using an ELISA, anti-endothelial cell antibodies (AECA) have been found in sera obtained at the time of renal biopsy in 46 out of 57 patients (81%) with systemic lupus erythematosus (SLE) and nephritis (mean binding index (BI) = 84% +/- 52.8) compared with 22 out of 50 SLE patients (44%) without nephritis (mean BI = 45% +/- 35.9).
