Abstract

Plasma fibronectin (cold-insoluble globulin) is known to be cross-linked to fibrin during the final stage of blood coagulation and is probably the major nonspecific opsonin of blood. We measured the concentration of plasma fibronectin in 36 hospitalized patients (11 with malignancy, 12 with infection, 13 with other underlying diseases) with evidence of fibrin depostion and lysis. Plasma fibronectin concentration was greater than 2 S.D. below the mean of normals in 17 of the patients (p less than 0.001). Depression of fibronectin was not related to severity of disseminated intravascular coagulation, as assessed by fibrinogen concentration and the quantity of FDP in serum. Depressed plasma fibronectin concentration and the quantity of FDP in serum. Depressed plasma fibronectin concentration was an unfavorable prognostic finding, inasmuch as 12 of the 17 patients with depressed fibronectin concentrations died during hospitalization as compared to five of the 19 patients with normal fibronectin concentrations (p less than 0.02). We speculate that specific depletion of plasma fibronectin, because of codeposition with fibrin or due to increased utilization as a nonspecific opsonin, may contribute to the organ failure seen in severely...Continue Reading

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
