Quantitative studies of the effects of defibrination (with ancrod) have been undertaken in two forms of allergic glomerular damage, nephrotoxic serum nephritis and acute serum sickness in rabbits. No differences in intrarenal fixation of nephrotoxic antibody, complement activation or host antibody response were detected between defibrinated and untreated rabbits with nephrotoxic serum nephritis. Defibrination prevented intraglomerular fibrin deposition in this disease; but some glomerular damage as shown by a rise in blood urea and endothelial proliferation still occurred in defibrinated animals. No differences in immune elimination of BSA, circulating immune complex formation or intrarenal localization of immune complexes were noted in defibrinated animals with acute serum sickness. No intraglomerular fibrin deposition was detected in treated or untreated animals in this disease model. It is concluded that the protective effects of ancrod are directly related to defibrination, and not to any other modification of allergic events.

One week after treatment with intravenously administered immune globulin and aspirin, a child with Kawasaki disease had persistent fever and an increase in coronary artery diameter to greater than 3 mm. Two additional doses of immune globulin were given intravenously. Rapid hemolysis occurred, followed by disseminated intravascular coagulation and serum sickness. Clinicians should be aware that immune globulin preparations contain antibodies to blood-type antigens that may cause significant hemolysis and disseminated intravascular coagulation.

Coagulation studies were performed in a patient who had been bitten by a snake of the species Bothrops neuwiedi. The patient presented with hemorrhagic necrosis at the envenomization site and considerable bleeding from venous puncture sites. He developed a severe defibrination syndrome with a clottable fibrinogen level of approximately 0.1 g/l. Fibrinogen was not measurable by clotting time assay. Fibrin degradation products were greatly elevated. Treatment with antivenom caused an anaphylactic reaction within ten minutes and serum sickness after three days. In vitro experiments revealed that B. neuwiedi venom directly activates Factors II and X, but does not activate Factor XIII. In vivo consumption of Factor XIII after B. neuwiedi envenomization is ascribed to the action of Factor IIa. At low venom concentrations clotting is initiated by activation of prothrombin by the venom either directly or via Factor X activation. Treatment with heparin might be beneficial in coagulopathy secondary to snake bite by reducing circulating active thrombin. The venom contains thrombin-like proteases which cause slow clotting of fibrinogen, and plasmin-like components causing further proteolysis of fibrinogen and fibrin. Antivenom has no effect on the proteolytic action of the snake venom. The in vivo effects of antivenom are presumably caused by acceleration of the elimination of venom components from the circulation. Intravenous administration of antivenom caused normalization of blood coagulation parameters within 48 h.
