Renal vein fibrin degradation products (FDP's) in glomerulonephritis.
In order to determine the role of intrarenal vascular coagulation (IVC) in chronic glomerulonephritis, coagulant parameters in renal blood (RVB), urine FDP's and renal histology were examined in 70 patients with chronic glomerulonephritis (CGN). RVB was obtained by Seldinger's technique. A correlation was obtained between an increase of fibrinogen, FDP and soluble fibrin monomer complexes (SFMC) in RVB and the degree of intraglomerular fibrin deposition shown on immunofluorescence. An increase of FDP's, SFMC and a slight decrease of fibrinolytic activity in RVB were observed in patients with CGN with decreased renal function or with the nephrotic syndrome. Daily excretion of FDP in the urine and the extent of intraglomerular fibrin deposition were greater in nephrotics than in non-nephrotics. We conclude that measurement of coagulation parameters in RVB is a reliable and sensitive method of assessing IVC, and that IVC plays an important role in aggravation of chronic glomerulonephritis, particularly when the nephrotic syndrome is present.
