The levels of protein C (PC) and other coagulation factors were monitored during endotoxin-induced disseminated intravascular coagulation (DIC) in the dog. Initial evaluation of the effectiveness of intradermal administration of bolus endotoxin quantities into the dog, demonstrated induction of DIC in the canine, without the severe side effects associated with bacterial sepsis. Quantitative determination of canine plasma protein C levels were performed using a multiple step amidolytic assay, that included a specific precipitation of the vitamin K-dependent proteins from citrated plasma, followed by thrombin activation (and neutralization) and subsequent measurement of the activated protein C (APC) by chromogen hydrolysis. This investigation demonstrated, that over a twenty-four hour interval, intradermal administration of endotoxin produces a gradual decrease in the PC activity levels, concomitant with a significant reduction in the Factor V, Factor VIII and fibrinogen levels and platelet count, and a prolongation of the Prothrombin Time and Partial Thromboplastin Time. During the first 6 hours, protein C levels fell below the pre-levels and remained significantly lower in the surviving dogs. Thus, this endotoxin-induced DIC animal model permits evaluation of various hemostatic parameters, yet diminishes the severe clinical findings associated with DIC.

Thirty-five patients with serious infections and impaired renal function were treated empirically with 2 to 8 g of cefoperazone per day. Infections included sepsis in 14, nonbacteremic urinary infections in nine, pneumonia in five, intra-abdominal infection in five, fasciitis in one, and malignant otitis externa in one. The average age of this group was 64.3 years, 25 had ultimately fatal underlying diseases, and their average serum creatinine level was 5.2 mg/dl. Infections were caused by Enterobacteriaceae in 23 patients, Streptococcus faecalis in five, Pseudomonas aeruginosa in four, Staphylococcus aureus in four, Hemophilus influenzae in three, and Staphylococcus epidermidis, Streptococcus pneumoniae, and Clostridium sordelli in one each. Overall, 32 patients had clinical and microbiologic cures, two had improvement, and one had failure. Hypoprothrombinemia occurred in 18 of 28 patients not given vitamin K for prophylaxis and occurred more often in those with serum albumin concentrations below 3.5 g/dl. Prothrombin times returned to normal within 36 hours of treatment with vitamin K, although two patients experienced mild hematemesis. In anicteric patients with liver function abnormalities, 2 g every 12 hours produced peak and trough serum concentrations that averaged 254 and 125 micrograms/ml, respectively, compared with 179.5 and 19.5 micrograms/ml, respectively, in five with normal liver function test results. In jaundiced patients treated with 1 g every 12 hours, trough concentrations were comparably elevated. Serum concentrations did not correlate with hypoprothrombinemia, but high levels throughout the dosing interval may have contributed to the excellent cure rate in this study.

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.

A conservative approach toward elective cholecystectomy in the patient with cirrhosis has been suggested because of the strong likelihood of excessive bleeding, sepsis, and multiple organ failure. We reviewed this problem in two medical centers, studying 27 patients with cirrhosis who had undergone nonemergency biliary tract surgery. Most patients had adequate liver function preoperatively. Most operations were cholecystectomies without duct exploration. Among factors analyzed were liver function tests, coagulation tests, and Child's classification. Prothrombin time was less than 2.5 s above control in 18 patients, more than 2.5 s above control in four patients, and not recorded in five patients. All survived the operation with benign postoperative courses. Only one patient had excessive bleeding; this patient had an elevated prothrombin time preoperatively. We conclude that elective cholecystectomy can be performed safely in patients with cirrhosis who have relatively normal liver function.

Central venous plasma concentrations of thromboxane B2 (TXB2) the stable metabolite of the vasoconstrictor platelet aggregator thromboxane A2, were measured in 12 patients with septic shock. In 8 patients dying with septic shock the concentration of plasma TXB2 (912 +/- 250 pg/ml) was ten times higher than that in 4 survivors of septic shock (92 +/- 25 pg/ml) and 6 controls (91 +/- 18 pg/ml). Prothrombin time and partial thromboplastin time were significantly prolonged in nonsurvivors compared with survivors. Similarly, the alveolar-arterial oxygen gradient was significantly raised in nonsurvivors (233 +/- 39 mm Hg) compared with survivors (112 +/- 47 mm Hg). This study demonstrates that the metabolism of arachidonic acid to thromboxanes is increased in patients dying of septic shock and this raises the possibility that thromboxanes may be involved in the disseminated intravascular coagulation and respiratory distress syndrome associated with severe sepsis.

Serum cholinesterase catalytic concentrations were estimated in 26 patients diagnosed as having systemic sepsis syndrome (septic shock) in the Intensive Care Unit (12 were admitted with the diagnosis of systemic sepsis syndrome while 14 patients developed the syndrome while in the unit) and in 66 normal, healthy subjects. The assay was performed for 7 consecutive days in the patient group. There was a very significant decrease in the level of cholinesterase in the patient group from the onset of the study as compared to the control group (P < 0.00001). This decrease remained during the course of the seven day study period, indicating hepatic dysfunction early in the diagnosis. When compared to other conventional liver function tests, serum cholinesterase seems to change earlier on in the diagnosis. Prothrombin time showed a pattern of change similar to that of serum cholinesterase. There was a significant relationship between the catalytic concentration of serum cholinesterase and the outcome of the systemic sepsis syndrome, the level being significantly lower in patients who died in comparison to those who lived. It seems that serum cholinesterase is a sensitive indicator of hepatic dysfunction in the systemic sepsis syndrome.

A post-dated intra-uterine growth retarded male Malay baby was born to a 30-year-old mother gravida II by Caesarean section. Her previous pregnancy ended in still-birth. The baby was severely asphyxiated at birth. He was intubated and immediately admitted to the neonatal intensive care unit. He had anasarca, anaemia, purpura and firm, massive hepatosplenomegaly. X-rays revealed ascites and bilateral metaphysiitis of the long bones. The haemoglobin level was 5.0 gm/dl and PCV 18.3%. Coombs' test was negative. Prothrombin time (PT) and partial thromboplastin time (PTT) were prolonged. The baby and mother were positive for Venereal Disease Research Laboratory (VDRL) and the treponema pallidum haemagglutination assay (TPHA) tests. The baby was actively resuscitated but expired at three and a half hours of life due to overwhelming sepsis associated with severe anaemia and disseminated intravascular coagulation.

Hyperimmunoglobulin E syndrome (HIE) is a disorder characterized by extremely elevated serum levels of IgE and recurrent infections. Patients are particularly predisposed to have staphylococcal abscesses, usually involving skin, lungs, and joints; but they are also at risk for infections with other bacteria and fungi. We report the case of a 46-month-old boy with HIE who had Candida endocarditis and sepsis with a large fungal mass extending through the tricuspid valve and into the surrounding heart tissue, requiring surgical excision and replacement with a prosthetic valve. He had an indwelling central line for previous antibiotic therapy and had oral thrush for a month before presentation, which had been treated with oral nystatin. He was first seen with very dark urine, a new murmur, petechial rash, in shock, and disseminated intravascular coagulation. The white blood cell count was 38,700 with 70% segmented neutrophils, 9% banded neutrophils, 15% lymphocytes, 4% monocytes, and 2% eosinophils. Hemoglobin was 7.1, and platelet count was 14,000. Prothrombin time was 15.5, and partial thromboplastin time was 31; fibrinogen level was 110 mg/ml, and fibrin degradation products were greater than 40 mg/ml. Serum IgE was 38,664 and 44,510 on repeat measurement. He has had recurrent staphylococcal pneumonias with pneumatoceles, twice requiring segmental lung resection. Blood and tricuspid valve cultures grew Candida albicans. He was treated with amphotericin and flucytosine, and later switched to fluconazole, with good response to therapy. A literature search revealed no other reported case of Candida endocarditis in patients with HIE. Fungai endocarditis is a rare complication, which may occur in patients with HIE and indwelling central catheters.

Sepsis is commonly associated with disturbances of the hemostatic balance. Most of the pathophysiological changes in sepsis are caused by endotoxin acting directly through endothelial injury or indirectly through release of cytokines with procoagulant effects. The relation between cytokines and hemostatic parameters was assessed in 32 patients with sepsis. Prothrombin fragment 1+2 (F1+2), thrombin-antithrombin III complexes (TAT), tissue type plasminogen activator (t-PA) functional and antigen, plasminogen activator inhibitor-1 (PAI-1), plasminalpha2-antiplasmin complexes (PAP), D-Dimer, thrombomodulin (TM) and von Willebrand factor (vWF) were measured in patients and in 30 healthy subjects. The levels of cytokines TNF-alpha and interleukin-6 (IL-6) also were determined. A significant increase of F1+2, TAT, PAI-1, PAP, and D-Dimer was observed in septic patients as compared with controls (p<0.0001), whereas t-PA activity was significantly reduced (p<0.01). The markers of endothelial cell activation TM, vWF, and t-PA antigen also were elevated significantly as compared with the control group (p<0.01). Finally, we found a marked increase of TNF-alpha and IL-6 (p<0.0001). Whereas the increase of cytokine levels could be partially responsible for the hemostatic activation, it did not correlate with markers of endothelial activation in patients with sepsis.

Bleeding due to coagulopathy is a frequent complication of severe sepsis, especially in burn patients. The primary treatment is aimed at the underlying cause but additional supportive measures, consisting mainly of coagulation factor replacement, are frequently necessary. We describe the salutary effect of continuous veno-venous haemofiltration (CVVH) with predilution on diffuse haemorrhage in a patient with severe septic shock and renal failure. The diffuse haemorrhage was initially treated with replacement of coagulation factors. Prothrombin time and partial thromboplastin time became normal while diffuse bleeding continued and the thrombelastogram showed evidence of fibrinolysis. A short period of CVVH lead to the cessation of bleeding which was reflected by a normal thrombelastogram.
