The evolution of coagulation abnormalities was studied in Russell's viper bite victims who, on admission to hospital, showed no clinical signs of systemic envenoming. Based on the laboratory results and subsequent clinical course, three groups were distinguished. The first group, consisting of five cases, showed no activation of coagulation at any stage. The second group, consisting of six cases, developed mild to moderate abnormalities in some tests, particularly in the aPTT and factor V assay, which corrected to normal without treatment. The third group, consisting of nine patients, developed haemostatic abnormalities as early as 1-2 h after the bite, which progressed to severe defibrination 4-8 h later at which time antivenom was given. Comparison of the haemostatic abnormalities in the three groups suggested that serial monitoring of the serum FDP concentration may be of value in predicting the likelihood of systemic envenoming and progression to complete defibrination.

Factors of coagulation and fibrinolysis have been evaluated in 15 patients with untreated acute nonlymphoblastic leukaemia (ANLL). 10 patients had major bleeding (MB) and 6 had laboratory signs of DIC. 5 patients went into complete remission (CR). Antithrombin III (AT III) was decreased in 7 patients, antiplasmin (AP) in 9, fibronectin (FN) in 6 and factor XIII in 4/12. The ratio between factor VIIIR:Ag and factor VIII:C was over 2.0 in 11 patients, and high values were especially seen in patients with MB and patients with DIC. Spontaneous proteolytic activity, measured with S-2288 was increased in 3 patients who all had MB, and none of whom achieved CR. 2 patients with promyelocytic leukaemia (M3) had low fibrinogen and AP, high FDP and normal AT III, speaking for primary fibrinolysis, which in addition to proteolytic enzymes in the blast cells are important contributing factors regarding MB in ANLL.

We investigated 22 severely ill patients (21 surgical, 1 medical) at the intensive care unit. Analyses of platelet count, Normotest, antithrombin III, FDP and fibrinogen were used to divide the patients into three diagnostic groups: DIC (3 positive tests), suspected DIC (2 positive tests) and No DIC. Using these criteria 9, 8 and 5 patients were referred to these diagnostic groups, respectively. Factor XII and prekallikrein did not differ significantly between the three diagnostic groups. On the other hand the capacity of the patient plasma to inhibit kallikrein was significantly lower in the DIC group. The decrease of kallikrein inhibitory capacity was correlated to the decrease of antithrombin III and alpha 2-antiplasmin. Out of the 22 patients in the study 8 patients died, 5 of these were in the DIC group. Non-surviving patients showed lower values of the protease inhibitors than survivors. It is concluded that in this type of patients and with the laboratory methods used contact phase factors do not seem to be affected in DIC. Analyses of the kallikrein inhibitory capacity, antithrombin and alpha 2-antiplasmin on the other hand seem to be of interest to measure, though the decrease of these inhibitors could be due to consumption as well as to reduced protein synthesis. Further studies are needed to prove the prognostic value of assaying these protease inhibitors.

Plasmapheresis (50 ml fresh frozen plasma/kg body weight per session--total 9-11 liters) was performed within 36 hours of the onset of septicaemia in 7 patients (1 woman and 6 men, age 14-48 years). One 8 year old girl was treated with exchange blood transfusion (2 liters). All had symptoms of severe septic shock caused by Neisseria meningitidis (6) or by Streptococcus pneumoniae (2). All patients demonstrated signs of DIC and concomitant fibrinolysis with low platelet values, normal to low fibrinogen levels, circulating soluble fibrin and increasing amounts of FDP. Persistent extreme values were observed in 2 patients that died, whereas coagulation/fibrinolysis parameters frequently improved during plasmapheresis and gradually (more than 6 days) returned to normal values in the survivors. Although plasmapheresis was largely successful and signs of DIC and fibrinolysis were normalized, 2 patients died and 1 survived with severe sequelae. Thus, it remains to accumulate more data to conclude if plasmapheresis is beneficial in the treatment of severe septic shock and DIC.

In a controlled study of fibronectin supplementation in sepsis, 11 ICU patients in septic shock were scheduled to receive either cryoprecipitate from 20-40 donors (n = 6) or 250-300 ml of stored plasma (n = 5) (two infusions over 24 h). We wanted to: compare some "conventional" DIC variables in the ICU (platelet count, prothrombin complex = NT, FDP) to additional variables: Fibronectin (Fn), fibrinogen (Fg), F V, FVIII R:Ag, F VIII:C activity, F XII, plasminogen (Plg), antiplasmin (AP), antithrombin (AT), kallikrein inhibiting activity (KI) and spontaneous proteolytic activity (SPA): study the effects of cryoprecipitate or plasma infusion on three variables. Samples were taken before the first infusion, and 24 and 48 h after. At onset, high levels (p less than .001 when compared to blood donors) of Fg, VIIIR:Ag and VIII:C were seen. KI levels were within the normal range. F V was low (p less than .05). Fn, NT, XII, Plg, AP and AT were markedly low (p less than .001). SPA showed great variation. When compared to 28 patients with severe infections, but not in septic shock, the ICU group had higher VIIIR:Ag (p less than .05) and VIII:C (p less than .01), and lower XII, Plg, AP and AT (p less than .001). FDP was elevated in all ICU patients. Five patients were thrombocytopenic, and in these a pattern with low levels of Plg and AT was observed. Fn did not correlate well to the other variables measured. These results indicate a marked activation of coagulation and fibrinolysis in these severely ill patients.(ABSTRACT TRUNCATED AT 250 WORDS)

The procoagulant cellular activity (PCA) of intact and lysed leukaemic cells was evaluated at diagnosis in 23 patients with acute non-lymphoid leukaemia (ANLL). The leukaemic cells of all 13 patients having DIC feature (excess of fibrin monomers, serum FDP and plasma fibrino-peptide A) showed a significant (P less than 0.0001) increase of PCA, while a pattern similar to that of normal granulocytes and lymphomonocytes was observed in the remaining 10 patients without evidence of DIC. When the patients were subdivided according to the FAB cytological classification, features of DIC and increased PCA were demonstrated in 3/3 M3 patients, 5/6 M5 patients and only in 5/14 remaining patients. These findings indicate that in ANLL patients: (1) the increased PCA of leukaemic cells is closely related to the occurrence of DIC; (2) the increased PCA seems related to the differentiation line and maturation level of the leukaemic cells.

The coagulation and fibrinolytic function of 100 cases (male 75, female 25) of trauma limited to the head was evaluated in acute phase. The coagulation and fibrinolytic function was evaluated by 6 parameters, consisting of platelet counts, PT, APTT, fibrinogen, serum FDP, and protamine sulfate test. Head injury was categorized into 5 groups according to CT findings: subdural hematoma (SDH: 13 cases), cerebral contusion (CC: 46 cases), epidural hematoma (EDH: 21 cases), skull fracture only (Fr: 14 cases), and cerebral concussion (Co: 6 cases). The results were as follows, in 19 dead cases, severe coagulopathy was observed. In intracerebral injury group (SDH + CC), serum FDP level was markedly elevated. The incidence of disseminated intravascular coagulation (DIC) following head injury was 24% (in dead cases 73.7% in survival cases 12.3%) of all cases, and mortality of cases with DIC was exceedingly high (58.3%). In 14 dead cases with DIC, the patients did not recover from DIC, and their mean survival time was only 89.2 hours. In 10 survival cases with DIC, the patients recovered from DIC. APTT was the most important to estimate the mortality of head injury. Thus, the evaluation of coagulation and fibrinolytic function in head injury in acute phase is not only important to know the occurrence of DIC, but also useful to predict the severity and prognosis of head injury.

A case of nontraumatic chronic subdural hematoma due to obstruction of dural vessels by tumor cells is presented and 25 reported cases are reviewed. A 39-year-old female was referred for headache, vomiting, disturbance of consciousness and right homonymous hemianopia with macular sparing. She had undergone mammectomy for medullary nodular carcinoma of the left breast five years before. She had been treated with combined hormonal therapy and chemotherapy for the cancer metastases to the liver in preceeding six months. Hematological examination revealed drug-induced thrombocytopenia, increase of FDP in blood (80 micrograms/ml), but no abnormality of prothrombin time and fibrinogen content. Therefore in the present case there was no evidence of disseminated intravascular coagulation (DIC) after Colman's criteria. However, it was suggested that this case had compensated DIC after Cooper's criteria. CT scan showed a biconvex-shaped low and partially iso-density area over the left fronto-temporal convexity, indicative of chronic subdural hematoma, and no abnormal findings in the occipital area. After removal of the hematoma she became alert without headache and vomiting. However, seven days later she complained of headache and vomiting again. Repeated CT scan showed a larger biconvex-shaped low density area over the left hemisphere extending to the parietal region at that time. Second operation was performed, but she expired four days later. Autopsy showed systemic metastases of the medullary nodular carcinoma in the scalp, temporal muscle and dura as well as lungs, adrenal glands, ovaries and bone marrow.(ABSTRACT TRUNCATED AT 250 WORDS)

In an experimental study in the rabbit, the modifications of some haemostasis parameters (platelet count, platelet retention and aggregation, platelet factors 3 and 4, platelet and plasma plasmin inhibiting activities, fibrinogen and other plasma factor levels, FDP), and histological findings are compared in both the normal animal and the animal with disseminated intravascular coagulation (DIC) induced by thrombin perfusion after administration of fibrinolytic inhibitors (plasminogen antiactivators and proteinase inhibitors). In the normal animal, the administration of fibrinolytic inhibitors is followed by haemostatic changes similar to those found in thrombophilic states. The modifications are more pronounced with plasminogen antiactivators than with proteinase inhibitors. In the animal with DIC, the administration of fibrinolytic inhibitors enhances the haemostatic and the biological disorders produced by thrombin perfusion. The effect of the plasminogen antiactivators is even more evident. The preventive administration of heparin reduces or abolishes the biological and histological disorders induced by thrombin; its beneficial effect is considerably reduced when thrombin is combined with fibrinolytic inhibitors. The administration of acetylsalicylic acid appears to be ineffective for the prevention of haemostatic and histological changes induced by thrombin perfusion.

A study was conducted on 40 patients with abruptio placentae complicated by intrauterine death of the fetus, consumption coagulopathy and uterine inertia. All patients had severe hyperfibrinolysis (FDP > 300 microgram/ml). Following correction of shock, amniotomy was performed, intrauterine pressure catheters were placed, and oxytocin infusions were begun in all cases. The diagnosis of uterine inertia was made when the cervix failed to dilate following six hours of this treatment. After diagnosing uterine inertia, 18 patients (group B) did not. All but one patient in group A showed a marked improvement in the associated consumption coagulopathy and a rapid reawakening of uterine activity with progress to spontaneous vaginal delivery. Thirteen patients in group B did not show prepartum improvement in consumption coagulopathy or a resumption of uterine activity. These patients required cesarean section. There were two maternal deaths in group B; the overall complication rate in this group was greater than in group A.
