The technique of plasma fibrinogen chromatography was used to study sequential changes in coagulant and fibrinolytic activity in six patients with severe pre-eclampsia. Plasma soluble fibrinogen-fibrin complex and plasma fibrinogen-fibrin degradation product levels were measured as indices of coagulant and fibrinolytic activity respectively. Clinical deterioration antenatally was accompanied by increasing coagulant and decreasing fibrinolytic activity, while a more stable clinical picture was associated with steady coagulant and increasing fibrinolytic activity. Following delivery, a surge in fibrinolytic activity accompanied or preceded clinical recovery. The pattern of increased coagulant and diminished fibrinolytic activity would seem to favour the development of disseminated intravascular coagulation in these patients and it is possible that the balance between coagulant and fibrinolytic activity may influence the clinical course and outcome of the pregnancy.

Hepatic rupture as a late complication of toxemic pregnancy is a rare yet lethal condition requiring rapid recognition and surgical management. The clinical triad of toxemia, right upper quadrant pain, and sudden hypotension is the diagnostic hallmark of presentation. Most patients present near the time of delivery and are found to have subcapsular hematomas of the right hepatic lobe with free rupture into the peritoneal cavity and resultant exsanguinating hemorrhage. The association of toxemia and disseminated intravascular coagulation with secondary microembolic damage to the liver and other organs has been discussed. Basic surgical principles in the managment of hepatic subcapsular hematomas, and the prolonged postoperative course and frequent complications in these patients have been stressed.

Using 125I-labelled fibrinogen the metabolism of this protein was studied in 29 patients with II-III stage congestive circulatory insufficiency due to ischemic heart disease and rheumatic heart diseases. It was established that with the progression of circulatory insufficiency fibrinogen half-life increased. The body content of total fibrinogen increased with the gradual intensification of circulatory insufficiency due to growth of the extravascular (noncirculating) fraction. The growth is associated with the intensified egress of circulating fibrinogen into the extravascular space (thrombus, tissue, etc.). The role of disseminated intravascular clotting and consumption coagulopathy in the pathogenesis of congestive circulatory failure is discussed.

Testing for soluble fibrin complexes was performed using a sensitive and reliable haemagglutination assay, with red cells sensitized by fibrin monomers. The principle is based on the fact that the monomers linked to red cells and induce their agglutination. This test, used in clinical trials, has revealed the presence of soluble complexes in every confirmed case of acute DIC, but also in Chronic DIC where diagnosis is difficult to establish (negative ethanol gelation test, normal or sub-normal levels of fibrin breakdown products). In Cirrhosis of the liver, the test gives positive results in a non negligible number of cases. Several hypotheses are made to explain why in certain confirmed cases of DIC, low fibrin breakdown products levels are found.

The results of this paper indicate that cattle infected with B. bovis (argentina) have a markedly altered and activated coagulation system. A degree of thrombin activation occurs due partly to release of thromboplastin-like substances from lysed erythrocytes but due primarily to activation of kallikrein by babesial proteases. This produces a hyperfibrinogenaemia, particularly in intact cattle, with soluble fibrin complexes constituting up to one-third of the total fibrinogen concentration. High molecular weight non-coagulable fibrinogen-like proteins are detected terminally but more so in splenectomized cattle. Plasminogen concentration decreases in splenectomized but not intact cattle while low molecular weight fibrinogen degradation products are not easily detected. It is suggested that a hypercoagulable intermediate state with little or no fibrin deposition occurs rather than terminal disseminated intravascular coagulation.

The correlation between disseminated intravascular coagulation (DIC) and pulmonary insufficiency following trauma and shock was studied in patients. Serial coagulation tests were performed on nine patients suffering from adult respiratory distress syndrome (ARDS), and six of nine showed the evidence of consumption coagulopathy. Heparin infusion was effective in two patients with the improvement of platelet counts, other coagulation factors and the concomitant improvement of lung function.

The role of disseminated intravascular coagulation (DIC) in the pathogenesis of adult respiratory distress syndrome (ARDS) was studied in the experimental animals. ARDS was simulated in dogs by the administration of various doses of Escherichia coli endotoxin (Difco). The alveolar surface activity in the group which received lethal dose of endotoxin (3 mg/kg) exhibited no significant alterations with mild pulmonary insufficiency and little pathologic change five hours after the induction of shock. On the other hand, a significant decrease in alveolar surface activity was found to develop in the group which received sublethal dose of endotoxin (1 mg/kg) accompanying enlarged alveolar-arterial oxygen tension differences (A-aDO2) and elevated pulmonary vascular resistance after 24 hours. These changes occurred concomitantly with pathologic findings of DIC, interstitial edema and atelectasis. The disturbance in ventilatory function observed in prolonged shock appeared to be related to the impairment of pulmonary microcirculation caused by DIC and subsequent hypoxia of lung tissue which led to a loss of alveolar surfactant.

Blood coagulation and fibrinolysis parameters were studied during 10 days of total fasting in healthy, normal weight males. A reduction of plasma levels of factor VIII activity with a concomitant decrease in factor VIII antigen was found, without other laboratory evidence for a disseminated intravascular coagulation. The effect of 10 days' starvation on blood coagulation appears to be small but the effect of more prolonged starvation might implicate impaired hemostasis.

The significance and frequency of fibrin thrombi (FT), the pathological hallmark of disseminated intravascular coagulation (DIC), in ischemic intestine were analyzed in a retrospective study of the infarcted bowel of patients with occlusive mesenteric ischemia (OMI) and nonocclusive mesenteric ischemia (NOMI). Representative intestinal sections were studied from 10 patients with NOMI of the small and/or large bowel and 12 patients, with OMI of varied etiology. Three patients with inflammatory bowel disease and 1 patient with DIC and bowel necrosis were also studied. Routine hematoxylin and eosin stains for fibrin were prepared for each specimen. The number of FT was quantitated. FT were identified in each of the 10 cases of NOMI; however in only 2 were they prominent. FT were identified in 6 of the 12 cases of OMI and in 4 of these 6 they were a prominent feature. Rare FT were present in the cases of inflammatory bowel disease and did not correlate with the inflammatory process. No FT were present in the intestinal sections of the DIC case. FT are a nonspecific feature of necrosis and can be identified in both occlusive and nonocclusive ischemic bowel disease. Their presence in the intestine of NOMI therefore cannot be used to implicate DIC as the primary cause of this entity.

Consumption coagulopathy is frequently observed in a resuscitation department. 120 cases of various etiologies are reviewed: complications of pregnancy (61 cases), infections (23 cases) or various stresses: acute hemolysis, shock, severe hepatic failure, intoxications, acidosis, heat-stroke... Consumption coagulopathy is intricated with the general stress which induces it, and with the visceral lesions induced by the stress and which can be aggravated by the consumption coagulopathy. The state of shock is observed in 76% of the cases, the haemorrhagic syndrome in 73%. Acute hemolysis and the clinical signs evocative of disseminated intravascular coagulation (cutaneous signs) are more rare. Following the initial manifestations, visceral complications may develop: renal, hepatic, respiratory, neurological, digestive. The evolution of the biology must be carefully studied. The diagnosis is made on both clinical and biological data. Etiological and pathophysiological treatment should be carried out. In our series, controlled and adapted heparin therapy was given systematically.
