Abstract | BACKGROUND AND PURPOSE: METHODS: Serum samples were collected from SLE patients with biopsy-proven lupus nephritis (n = 32), stable SLE patients (n = 32) and healthy controls (n = 32). The SLE Disease Activity Index (SLEDAI) of SLE patients was scored, and levels of anti-endothelial cell antibodies ( AECA) and anti-endothelial activities in serum samples were measured by cell- enzyme-linked immunosorbent assay and crystal violet assay, respectively, using cultured human endothelial EA.hy926 cells. RESULTS: Significantly higher AECA (p<0.001) and anti-endothelial activities (p<0.001) were found in sera from patients with lupus nephritis compared with that from stable SLE patients or controls. Moreover, AECA titers (p<0.001) and anti-endothelial activities (p<0.001) were strongly correlated with SLEDAI scores in these patients. CONCLUSION: The strong correlations of AECA and anti-endothelial activity with lupus nephritis activity support an endothelial origin for renal complications in Taiwanese SLE patients.
