Apoptosis in the kidneys of patients with type II diabetic nephropathy.

@article{citeulike:1689837, abstract = {The occurrence and extent of apoptosis in the kidneys of patients with diabetic nephropathy is largely unknown. We evaluated apoptosis in renal biopsies obtained from patients with early or advanced type II diabetic nephropathy. Apoptosis was about 6- and 3-fold higher, respectively, in glomeruli and tubules in kidneys of patients with early nephropathy than in the normal kidney and this was not further increased in advanced diabetic nephropathy. Glomerular apoptosis was related directly to hemoglobin A1(c) and systolic blood pressure, whereas tubular cell apoptosis correlated to diabetes duration and low-density lipoprotein-cholesterol. Fas, Fas ligand, and p38 mitogen-activated protein kinase expressions were enhanced in glomeruli and tubules; however, this did not correlate with apoptosis. In patients with proteinuria, apoptosis was associated with the subsequent loss of kidney function. When these parameters were subjected to multivariate analysis, only glomerular apoptosis retained a significant independent predictive value. Our findings suggest that apoptosis might be a clinically relevant mechanism of glomerular and tubular cell loss in proteinuric type II diabetic patients.Kidney International advance online publication, 12 September 2007; doi:10.1038/sj.ki.5002531.}, address = {1Nephrology Division, Department of Internal Medicine, Genoa University, Genoa, Italy.}, author = {Verzola, D and Gandolfo, M T T. and Ferrario, F and Rastaldi, M P P. and Villaggio, B and Gianiorio, F and Giannoni, M and Rimoldi, L and Lauria, F and Miji, M and Deferrari, G and Garibotto, G }, citeulike-article-id = {1689837}, doi = {http://dx.doi.org/10.1038/sj.ki.5002531}, issn = {0085-2538}, journal = {Kidney Int}, keywords = {apoptosis, dn, human}, month = {September}, posted-at = {2007-09-24 16:56:31}, priority = {2}, title = {Apoptosis in the kidneys of patients with type II diabetic nephropathy.}, url = {http://dx.doi.org/10.1038/sj.ki.5002531}, year = {2007} }
