Title: [Studies of urinary proteins, FDP (fibrinogen degradation products), and NAG (N-acetyl-beta-D-glucosaminidase) in renal transplanted patients]. Author: Kunikata S, Ikegami M, Imanishi M, Nishioka T, Ishii T, Uemura T, Kanda H, Matsuura T, Akiyama T, Kurita T. Journal: Hinyokika Kiyo; 1989 Aug; 35(8):1299-304. PubMed ID: 2816597. Abstract: The urinary proteins, FDP (fibrinogen degradation products), and NAG (N-acetyl-beta-D-glucosaminidase) in renal transplanted patients were studied. SDS (sodium dodecyl sulphate) electrophoresis was used for the differentiation of urinary proteins according to their molecular size. In the azathioprine-treated patients with stable renal function, most of the urinary proteins were albumin. However, the low molecular weight (LMW) proteins, which were suggestive of tubular proteins, appeared in the urine of the ciclosporin-treated patients with stable renal function. During the rejection episodes of the ciclosporin-treated patients, the fraction of LMW proteins increased. The elevation of urinary FDP and NAG index (urinary NAG/urinary Cr) were detected in association with rejection episodes. Urinary NAG index increased in proportion to the elevation of serum Cr. However, the elevation of urinary NAG index was found in some ciclosporin-treated patients with normal serum Cr. The elevation of NAG index without the elevation of urinary FDP occurred in ciclosporin nephrotoxicity. The SDS electrophoresis of urinary proteins, urinary FDP, and urinary NAG index can be useful parameters for monitoring ciclosporin nephrotoxicity.[Abstract] [Full Text] [Related] [New Search]
