In order to clarify the abnormalities of intra-glomerular coagulation and fibrinolysis in patients with various renal diseases, urinary fibrin/fibrinogen degradation products (FDP) have been examined by several methods. We established a highly sensitive new method of enzyme-linked immunosorbent assay for urinary FDP. The results were as follow: 1) The mean +/- SD of urinary FDP in normal subjects was 10.30 +/- 9.08ng/ml. 2) The urinary FDP levels in chronic glomerulonephritis, nephrotic syndrome and chronic renal failure patients were significantly higher than normal subjects, and the levels in SLE, Alport's syndrome patients were higher than normal subjects. 3) The urinary FDP levels were a little bit higher in the patients with proliferative glomerulonephritis than in chronic glomerulonephritis patients with minor lesion or membranous nephropathy. 4) There was significant correlation between urinary FDP and urinary protein in chronic glomerulonephritis, while there was no correlation in nephrotic syndrome. 5) There was no correlation between urinary FDP and intra-glomerular fibrin deposits examined by immunofluorescent study in chronic glomerulonephritis, while in nephrotic syndrome, there were high levels of urinary FDP in the positive fibrin deposits cases. These results suggested that the most of the part of excretion of the urinary FDP in chronic glomerulonephritis is associated with the filtration of blood FDP to urine through the glomerular basement membrane, while in the nephrotic syndrome cases the origin of urinary FDP is related to the filtration and/or the intra-glomerular coagulation abnormalities.

UI MeSH Term Description Entries
D007674 Kidney Diseases Pathological processes of the KIDNEY or its component tissues. Disease, Kidney,Diseases, Kidney,Kidney Disease
D008297 Male Males
D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D009404 Nephrotic Syndrome A condition characterized by severe PROTEINURIA, greater than 3.5 g/day in an average adult. The substantial loss of protein in the urine results in complications such as HYPOPROTEINEMIA; generalized EDEMA; HYPERTENSION; and HYPERLIPIDEMIAS. Diseases associated with nephrotic syndrome generally cause chronic kidney dysfunction.

D004797 Enzyme-Linked Immunosorbent Assay An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.
