Abstract:
BACKGROUND: Endothelin-1 has been found to be a potent mitogen in cultured mesangial cells. In addition, the urinary hyperexcretion of endothelin-1 was observed in patients with glomerulonephritis. METHODS: The author studied endothelin-1 immunoreactivity in 64 kidney biopsies of patients with various glomerular diseases by immunoperoxidase staining utilizing anti-endothelin-1 serum from the rabbit. RESULTS: A group of Ig A nephropathy with glomerular proliferative change (8 focal glomerulonephritis and 7 diffuse mesangial proliferative glemerulonephritis) and a group of other proliferative glomerulonephritis (11 membranoproliferative glomerulonephritis type I, 5 poststreptococcal glomerulonephritis, 8 focal or diffuse proliferative lupus nephritis) have more prominent endothelin-1 protein expression in the glomerular endothelium, the vascular endothelium and the tubular epithelium than non-proliferative glomerular disease group (12 minimal change nephrotic syndrome, 7 membranous nephropathies, 6 IgA nephropathies with minor glomerular abnormality). CONCLUSION: These results suggest that endothelin-1 has a potential role in the pathophysiology of proliferative glomerualr diseases.
