In children with several kinds of renal diseases, fragments of urinary fibrin/fibrinogen degradation products (FDP) and crosslinked fibrin degradation products (XLFbDP) were investigated by autoradiography using western blotting method. Results were compared with distribution and immunological features of intraglomerular fibrin/fibrinogen related antigen (FRA) based on immunohistopathologic method containing monochloroacetic acid (MCA) treatment. In patients with minimal change nephrotic syndrome or membranous nephropathy, crosslinked fibrin (XLFb) was not present in their glomeruli, and urinary FDP were composed of fibrinogen degradation products (FgDP) such as X, Y and D. On the other hand, in cases of proliferative glomerulonephritis such as Henoch-Schönleinpurpura nephritis or IgA nephropathy, XLFb was frequently observed along glomerular capillary walls. In these cases, urinary FDP were composed of XLFbDP (D-dimer) togetherwith FgDP. It was concluded that the presence of D-dimer in the urine suggested intraglomerular XLFb, but some part of urinary FDP, especially FgDP, were derived from plasma fibrinogen or FDP.
