Diagnosis of disseminated intravascular coagulation (DIC) was made in 64 cases (16.2%) among a total of 395 autopsy cases. There were 31 men and 33 women. Their ages ranged from 31 to 91 years (mean 76.3). Underlying diseases were mainly malignancy and
sepsis
. Fresh cardiac lesions were found in 40 cases (62.5%). Coronary thrombosis was found in 13 cases (20.3%) and myocardial necrosis in 24 cases (37.5%), with acute myocardial infarction in 9 and focal necrosis in 15. Nonbacterial thrombotic endocarditis was found in 17 cases (26.6%), mural thrombi in 11 (17.2%), and bleeding of the heart in 11 (17.2%). Platelet count,
fibrinogen
and euglobulin lysis time were not correlated with myocardial necrosis nor coronary thrombosis. Increase of fibrin degradation products correlated with the presence of coronary thrombosis with or without myocardial necrosis. DIC was found with a high incidence in the aged, and many of them were complicated with fresh cardiac lesions. Development of acute myocardial infarction depends on the small thrombi in the severe stenosis of the main coronary arteries or on the multiple microthrombi in the peripheral coronary branches.

A critically ill patient with disseminated intravascular coagulation (DIC) secondary to gram negative
septicemia
is reported. Low dose (5-10 mu/kg/h) heparin by intravenous infusion promptly inhibited intravascular coagulation, as reflected by laboratory studies. Fibrin monomer (FM) became undetectable, concentration of fibrin degradation products (FDP) fell,
fibrinogen
rose, and the activated partial thromboplastin time (PTT) shortened. Unintentional, temporary interruption of heparin resulted in transient return of abnormal laboratory values. The patient went on to make a complete recovery. Although the therapeutic contribution of heparin could not be proven in this patient, the laboratory data suggested that it was a valuable adjunct and in the dosage given unlikely to potentiate bleeding. The monitoring of heparin therapy in DIC by measurement of FDP, FM, and
fibrinogen
rather than clotting time is recommended.

The study included 28 infants with infectious gastroenteritis who evolved with disturbances of coagulation and in whom laboratory tests were practiced by micromethods through capillary puncture. The most frequently seen abnormality was a combination of vitamin K dependent factors deficiency with thrombocytopenia. Another observation in our study is that hypofibrinogenemia in infants with infectious gastroenteritis is not always secondary to disseminated intravascular coagulation. A decrease in
fibrinogen
in these cases is explained by a lack in synthesis of this factor in infants with malnutrition since out of 16 malnourished infants, 75% evolved with hypofibrinogenemia, while eutrophic infants evolved with normal
fibrinogen
. The disseminated intravascular coagulation syndrome was seen more frequently in patients with infectious gastroenteritis complicated with
septicemia
and shock, 57% of the patients did not show manifestations of bleeding nor of thrombosis which justifies in these cases a systematic investigation of the coagulation mechanism.

The DIC syndrome is the most common cause of an abnormal hemorrhage tendency during pregnancy and the puerperium and reflects systemic activation of the coagulation cascade by circulating thromboplastic material, with secondary activation of the fibrinolytic system. Its presence in a pregnant patient almost invariably is evidence of an underlying obstetric disorder such as abruptio placentae, eclampsia, retention of a dead fetus, amniotic fluid embolism, placental retention or bacterial
sepsis
. Diagnosis of the DIC syndrome rests on the demonstration of reduced levels of
fibrinogen
and platelets, prolongation of the thrombin, prothrombin and partial thromboplastin times, and the presence of fibrin/
fibrinogen
degradation products (FDP) in the serum. Therapy consists of prompt removal of the source of procoagulant material, replacement of depleted clotting factors and, in some cases, anti-coagulation with heparin.

Serial measurements of coagulation activity, platelet counts, and platelet aggregation were done in patients with full-thickness burns involving 25% or more of body surface area to detect specific changes that might correlate with the onset of
septicemia
. Mean and maximal values for prothrombin time, partial thromboplastin time, thrombin time, activities of factor V and factor VIII, and concentrations of
fibrinogen
and
fibrinogen
-related antigens observed in the presence of bacterial
septicemia
did not differ significantly from those observed in the absence of
septicemia
. Mean platelet counts were significantly less with
sepsis
, but values in individual subjects were not indicative of the presence of
septicemia
. By contrast, platelet aggregation in response to adenosine diphosphate, epinephrine, and collagen always became severely abnormal with the onset of
septicemia
but not in the absence of
sepsis
.

The pathogenesis of experimental meningococcal
septicemia
and the efficacy of heparin sodium therapy were evaluated by inoculating rabbits intraperitoneally with type B meningococci in mucin. Half the rabbits died, and the respiratory distress and circulatory failure that occurred during the terminal phase of the disease were associated with diffuse pulmonary capillary and venular thrombosis and with renal glomerular fibrin deposition. Platelet and leukocyte counts and plasma
fibrinogen
levels decreased in all rabbits, and prothrombin and partial thromboplastin times were prolonged. Pretreatment with heparin sodium diminished intravascular fibrin deposition but failed to prevent the pulmonary microthrombi and did not either reduce the mortality or improve the survival time. We conclude that death in meningococcal
septicemia
is due to widespread thrombosis of the pulmonary microcirculation. The disease is complicated by diffuse intravascular coagulation, which can be controlled with heparin sodium but which is not immediately life-threatening.

Fibrinogen
survival using 125I-labelled homologous
fibrinogen
was studied in 17 adults with acute leukemia. Five patients in complete remission had normal
fibrinogen
survival and turnover rate. Five of 6 patients undergoing induction therapy and 4 of 6 in relapse had shortened
fibrinogen
survival; the turnover rate was increased in all 12 patients. Nine of 12 patients with active disease had elevated levels of
fibrinogen
degradation products in the serum. Serial coagulation studies did not support the diagnosis of overt disseminated intravascular coagulation. There was no correlation between the morphological type of leukemia, chemotherapy, the presence of fever and
sepsis
, or liver dysfunction and
fibrinogen
survival. Other possible causes of the accelerated
fibrinogen
turnover in patients with active disease are discussed.

In 339 patients with various diseases factor XIII (FSF) was determined with the specific amine incorporation method of Lorand et al (1969). Normal values were found in patients with renal (216 patients) or liver diseases (33 patients), in 39 patients with recurrent deep venous thrombosis and in 17 children with congenital cyanotic heart disease. Low levels were found in patients with various conditions, such as
sepsis
, multiple fractures and combustio complicated by an abnormal proteolytic activity (fibrinolysis and/or activation of the coagulation system with signs of disseminated coagulation). No correlation was found between the FSF and the
fibrinogen
values or the levels of fibrin/
fibrinogen
degradation products (FDP). Low FSF values were found in 4 patients with erosive gastritis, with gastrointestinal bleedings and a local fibrinolytic activity in the gastric juice. Although the FSF must be very low (smaller than 1%) if it is to cause bleedings, the low levels in these patients with many other coexisting disturbances in the coagulation system and/or an increased fibrinolytic activity most probably contribute to the increased bleeding tendency in such patients.

Blood rheologic measurements together with peripheral resistance determinations in vivo were made in 27 critically ill patients. Eighteen of these patients (group I) suffered from violent trauma or operative injury and the other 9 (group II) were patients with generalized
sepsis
. As a result of fluid therapy all patients underwent hemodilution, resulting in a decrease in blood viscosity. This drop in blood viscosity was counteracted to some extent by an increased plasma viscosity due to elevated
fibrinogen
levels and a decreased red cell deformability associated with massive transfusions of stored blood. The correlation of vivo hemodynamics with blood rheological data made it possible to separate the relative roles of vascular dimensions and blood viscosity in affecting the total peripheral resistance. This approach permitted us to distinguish varying degrees of vasoconstriction in nonseptic patients in low flow states (group I) and varying degrees of vasodilation in septic patients (group II). This type of analysis serves to elucidate the pathophysiology of hemodynamic alterations in disease and provides a rational basis for devising an effective therapeutic program.

Disseminated intravascular coagulation (DIC) is a syndrome caused by the systemic generation of thrombin. Most cases are due to pathological activation of the intrinsic coagulation systems (e.g. in
sepsis
), and/or the extrinsic system (e.g. in malignancy and head trauma). Diagnosis is made by finding abnormalities in at least 3 of 4 laboratory values, namely prothrombin time, platelet count,
fibrinogen
and
fibrinogen
/fibrin degradation products. The most common clinical manifestation of DIC is bleeding, with thrombosis in less than 10% of acute cases but more frequently encountered in chronic DIC associated with malignancy. Acute DIC must first be treated by specific therapy of the underlying disease and general support measures. If serial clinical and laboratory monitoring improves, no further treatment is required. If severe or life-threatening haemorrhage occurs or a thrombotic event ensues, heparin anticoagulation followed by aggressive replacement with platelets, fresh plasma and possibly cryoprecipitate is indicated. Heparin doses should be 'therapeutic' (i.e. adequate to overcome the coagulant forces that may have produced a relative heparin-resistant state in the blood). Chronic DIC with haemorrhage, or more usually thrombosis, should also be treated with heparin; warfarin is ineffective. If DIC persists because, for example, a tumour does not regress, long term outpatient subcutaneous heparin therapy may be required.
