The pathogenetic significance of intravascular coagulation in experimental acute renal failure. 1978

Serum and urine fibrin(ogen) degradation products (FDP), FDP clearances, and serum urea nitrogen (SUN) concentrations of rats challenged with glycerol-induced myohemoglobinuria were measured serially over a period of 4 days. The results obtained in animals that developed acute renal failure (ARF) were compared with those obtained in rats made refractory to renal failure by long-term salt loading or recent recovery from prior renal failure. Only the rats susceptible to ARF experienced a major rise in serum FDP concentration. Urine FDP excretion rose most markedly in the same rats but, being elevated in all groups. showed the utilization of fibrinogen whether serum FDP values increased or not. The results obtained might reflect differences in the degree of intravascular coagulation which are pathogenetically important. It is possible, however, that increased serum FDP concentrations found exclusively in rats with ARF are the results rather than the cause of impaired filtration, and that reduced tubular absorption may at least partly account for the high urinary FDP excretion observed in this model of experimental acute renal failure.

D009212 Myoglobinuria The presence of MYOGLOBIN in URINE usually as a result of rhabdomyolysis. Myoglobinurias
D001803 Blood Transfusion The introduction of whole blood or blood component directly into the blood stream. (Dorland, 27th ed) Blood Transfusions,Transfusion, Blood,Transfusions, Blood
D001806 Blood Urea Nitrogen The urea concentration of the blood stated in terms of nitrogen content. Serum (plasma) urea nitrogen is approximately 12% higher than blood urea nitrogen concentration because of the greater protein content of red blood cells. Increases in blood or serum urea nitrogen are referred to as azotemia and may have prerenal, renal, or postrenal causes.

D004211 Disseminated Intravascular Coagulation A disorder characterized by procoagulant substances entering the general circulation causing a systemic thrombotic process. The activation of the clotting mechanism may arise from any of a number of disorders. A majority of the patients manifest skin lesions, sometimes leading to PURPURA FULMINANS.

D006456 Hemoglobinuria The presence of free HEMOGLOBIN in the URINE, indicating hemolysis of ERYTHROCYTES within the vascular system. After saturating the hemoglobin-binding proteins (HAPTOGLOBINS), free hemoglobin begins to appear in the urine.
