The activity of the extrinsic pathway inhibitor (EPI), which is the factor-Xa-dependent inhibitor of the factor VIIa-tissue
thromboplastin
complex, was serially determined in 13 patients with postoperative/posttraumatic
septicemia
, and compared to the activity of antithrombin (AT), heparin cofactor II and protein C (PC). In the survivors (n = 8), initial low values for all the inhibitors normalized during recovery. In the demises (n = 5), a progressive increase in EPI activity was observed until death, whereas progressive decreases were observed for the other inhibitors. No correlation was found between the inhibitor values and the endotoxin concentration. We conclude that EPI activities are increased in the late course of fatal
septicemia
. Apparently, a large EPI-AT gap is a severe prognostic indicator in such patients.

A patient with T-polyagglutinable red cells and a severe coagulopathy provided an opportunity to observe the results of plasma transfusion in the face of T-activation. The patient was a 52-year-old Navajo Indian with a perforated gall bladder and related
sepsis
due to Clostridium perfringens. The gall bladder was removed surgically. Postoperatively, he had severe thrombocytopenia, and prolonged partial
thromboplastin
and prothrombin times. The patient's red cells were agglutinated by Arachis hypogaea and Glycine soja lectins but were unagglutinated by extracts of Salvia horminum, Salvia sclarea, and Bandeiraea simplicifolia. No untoward reactions or any evidence of hemolysis were observed when the patient was given platelet concentrates and 4 units of single-donor plasma. Serial plasma hemoglobin and haptoglobin levels documented that there was no hemolysis. His coagulopathy responded, and he had a successful surgical re-exploration and recovery. This case documents that serious adverse consequences do not necessarily follow transfusion of plasma in a recipient with T-activated red cells. T-activation is a relative but not absolute contraindication to plasma transfusion.

Adult respiratory distress syndrome (ARDS) is a complex pulmonary clinicopathologic condition associated with pulmonary endothelial injury and blood coagulation activation. In patients with ARDS from all causes, factor VII levels were significantly reduced. Patients with ARDS caused by
sepsis
had more evidence of intravascular coagulation and fibrinolysis than did patients with trauma-related ARDS by having significantly (p less than or equal to 0.05) increased prothrombin times, activated partial
thromboplastin
times, and fibrin degradation products, and decreased antithrombin III concentration. We sought to determine whether the proteins of the contact system of plasma proteolysis (factor XII, prekallikrein, high molecular weight kininogen, and C1 inhibitor) were also activated after acute lung injury. Patients with ARDS caused by either trauma or
sepsis
had significantly (p less than or equal to 0.01) reduced factor XII levels, high molecular weight kininogen functional activity, prekallikrein activity, and prekallikrein antigen levels compared with controls. In both the
sepsis
-related and trauma-related ARDS groups, C1 inhibitor activity was significantly reduced but C1 inhibitor antigen levels were significantly elevated from control. These findings showed that the proteins of the contact system were more extensively activated in ARDS than were the proteins that contribute to later reactions in intravascular coagulation and fibrinolysis. Activation of the contact system proteins could be the result of endothelial injury occurring as part of ARDS. Intravascular coagulation and fibrinolysis in patients with ARDS also arise from components independent from contact system activation.

Infected patients with hematological disorders were treated with the combination of cefmenoxime (CMX) and cefsulodin (CFS). This therapy was done on 74 patients, of whom 38 (51%) had acute myelocytic leukemia, 14 (19%) malignant lymphoma, 7 (9%) acute lymphocytic leukemia, 5 aplastic anemia, 4 adult T cell leukemia, 4 chronic myelocytic leukemia, 1 multiple myeloma and 1 histiocytic medullary reticulosis. Complicated infections included 5 cases of
septicemia
, 41 cases of suspected
septicemia
, 19 cases of respiratory tract infection, 2 with anal abscess, 1 with urinary tract infection and others. The obtained results were as follows: Clinical effectiveness of the combination therapy was excellent in 17 cases (23.0%), good in 24 (32.4%) and poor in 33 (44.6%). Total clinical efficacy rate was 55.4%. Clinical efficacy rate was 40% against septicemias, 51.2% against suspected septicemias and 57.9% against respiratory tract infections. Causative pathogens were isolated in only 21 cases (28.4%): Gram-positive bacteria in 9 cases, Gram-negative bacteria in 11 and fungus in 1. About half of the Gram-negative bacteria belonged to Pseudomonas sp. The efficacy rate of this combination therapy against Gram-negative bacterial infections was 72.7% but the rate against Gram-positive bacterial infections were only 33.3%. Only in 1 case, this combination therapy was discontinued because of drug eruption. Abnormal laboratory findings were observed in 5 cases: Elevation of BUN in 3, GOT and GPT in 1 and prolongation of activated partial
thromboplastin
time in 1. In conclusion, this combination therapy of CMX and CFS is useful and safe against infections complicated by hematological disorders.

The author analyses the reported data and his own findings concerned with the involvement of mononuclear phagocytes in the regulation of hemostasis and in the pathogenesis of a number of frequently occurring forms of the hemostatic system pathology. The content of monocytic
thromboplastin
was measured in 56 patients with the intravascular blood coagulation syndrome of varying etiology. Production of monocytic
thromboplastin
reached the highest degree in patients with purulent conditions whereas in patients presenting with the terminal stage of
sepsis
, it did not exceed normal or even dropped down, which may be connected with depletion of monocytes because of their preliminary hyperactivation.

Gram-negative septic shock remains a major clinical problem. One frequently encountered complication of
sepsis
is disseminated intravascular coagulation (DIC). The present study was to determine in an Escherichia coli endotoxemia awake rat model the efficacy of antithrombin-III (AT-III) prophylaxis and to explore the role of DIC in the pathogenesis of endotoxemia. We demonstrated that DIC occurs very early, before the appearance of detectable serious abnormalities in cardiovascular, metabolic, and biochemical variables indicative of organ damage or dysfunction; AT-III prophylaxis significantly ameliorates DIC, as evidenced by completely preventing the fall in plasma fibrinogen concentration and significantly limiting the increases in prothrombin time and activated partial
thromboplastin
time after 4 hours of endotoxemia; and AT-III prophylaxis dramatically increases permanent survival. Results of this study suggest that AT-III prophylaxis is very protective above a threshold dosage in an endotoxemic rat model and that protection is in part due to ameliorating DIC. Our data also suggest that DIC occurs very early during endotoxemia and may in part be responsible for the pathogenesis of endotoxemia in the rat. We conclude that AT-III prophylaxis may be efficacious in conditions of impending DIC, such as gram-negative
septicemia
/endotoxemia.

Rats were subjected to gram-negative
septicemia
induced by cecal perforation or were sham-operated. Thromboplastin values increased in blood monocytes (40-fold), peritoneal macrophages (115-fold) pleural macrophages (5-fold), splenic macrophages (3-fold), and lung alveolar macrophages (1.4-fold) in septic animals as compared to controls. In septic animals disseminated intravascular coagulation was evidenced by a significant (p less than 0.05) fall in fibrinogen, factor VII, X and platelets. A simultaneous and significant (p less than 0.05) decrease in
thromboplastin
content of tissue-specimens from lung and spleen was observed in rats with
septicemia
, whereas increased
thromboplastin
values were demonstrated in tissue-samples from cecum - the infectious focus. This might reflect mobilization of mononuclear phagocytes in favour of the site of infection.

The relationship between mononuclear phagocyte
thromboplastin
activity, microorganisms and levels of endotoxin in peritoneal fluid and splanchnic and systemic circulation was evaluated during experimental endogenous gram-negative peritonitis in the rat. Significant rise in
thromboplastin
activity of mononuclear phagocytes was demonstrated in all three compartments. This newly synthesized
thromboplastin
is a trigger for important biologic systems such as the coagulation cascade, and thus may play a major role in the development of disseminated intravascular coagulation so often occurring in gram-negative
sepsis
. It probably also participates in the formation of fibrous intraabdominal adhesions. Aerobic and anaerobic microorganisms together with endotoxin were detected already 1 1/2 hours after induction of peritonitis, and subsequently were found to increase in parallel fashion. Determination of endotoxin is a rapid and seemingly reliable method for early detection of gram-negative infection and thus may be of clinical value.

Tissue
thromboplastin
generation in monocytes was studied during various stages of Escherichia coli endotoxinaemia in pigs. The pigs were monitored in halothane anaesthesia and mechanically ventilated. Blood was sampled from the superior caval vein before and during endotoxin infusion and up to 6 hours after its start. Monnuclear leukocytes were harvested with Lymphoprep separation and monocyte counts were made, using TRITC-labelled sheep erythrocytes, acridine orange and a fluorescence microscope. Thromboplastin was quantified in a two-stage assay by incubating the test sample together with purified factor X, factor VII and Ca++. The generated
factor Xa
was thereafter assayed. There was statistically significant increase of tissue
thromboplastin
activity in monocytes after endotoxin infusion. Maximum level was reached at the end of the infusion and was maintained throughout the observation period. Decrease occurred in platelets, leukocytes, antithrombin III, fibrinogen and clotting factors V, VII and VIII, and clotting time was prolonged. These findings indicated significant disseminated intravascular coagulation. The endotoxin-stimulated monocytes with their elevated tissue thrombo-plastin activity thus may play an important part in development of the DIC which so often follows
septicemia
.

Factors associated with prolongation of the prothrombin time were analyzed in 94 patients with intra-abdominal
sepsis
. Patients were randomized prospectively to receive either the combination of tobramycin and clindamycin (TM/C) or moxalactam (MOX). This paper presents a retrospective review designed to compare the frequency of prolonged clotting times and to analyze predisposing factors. Prothrombin time (PT) prolongation occurred more frequently in patients given moxalactam (19 of 47 patients) than in patients given the combination of tobramycin and clindamycin (9 of 47 patients) (p less than 0.05). Prolongation of the partial
thromboplastin
time (PTT) occurred in all patients with a prolonged PT. Liver disease, upper gastrointestinal surgery, and use of cimetidine were more frequent in those patients with abnormal PT/PTT values (p less than 0.05). Two moxalactam-treated patients with subsequent PT/PTT prolongation had individual clotting factors assayed before moxalactam treatment and at the time of detection of the abnormal PT. The activity of clotting factors II, VII, VIII, IX, X, and XII was reduced during MOX therapy. Treatment with vitamin K reversed the abnormality. In view of underlying abnormalities and rapid response to parenteral vitamin K, the mechanism is probably an acute vitamin K deficiency superimposed upon chronic vitamin K deficiency. In patients with intra-abdominal infection, those treated with MOX are more likely to develop abnormal PT than those treated with TM/C. Since abnormal PT/PTT was common even in TM/C patients, supplemental vitamin K should be considered for all seriously ill, older patients with abdominal infections.
