Vitamin E pretreatment significantly prevented E. coli-induced Disseminated Intravascular Coagulation (DIC) in rats (1). DIC, a reduction in fibrinogen and a falling platelet count and diffuse haemorrhage are part of the clinical features of Haemorrhagic Shock Encephalopathy Syndrome (HSES), recognised as a disease entity in the 1980s (2). At the SIDS Conference 1974 Reisinger described the effect of Escherichia coli (E. coli) endotoxin on the rabbit (3). An early effect was a reduction in fibrinogen and a falling platelet count, resulting in the release of relatively large amounts of the neuro-transmitter serotonin, stored in platelets (3, 4). Fibrinogen inhibited the release of serotonin from platelets (24). Serotonin is released from platelets during platelet aggregation (14). Platelet aggregation is inhibited by vitamin E (1). Serotonin is a neuro-transmitter associated with deep sleep, respiratory movements and cardiovascular collapse (3). Death at a later stage involved vascular permeability, edema and haemorrhage. After fibrin-platelet clots had formed DIC was present in lungs, kidneys and other organs (3). Medical researchers in Australia linked almost half of SIDS victims with a poisonous strain of intestinal E. coli bacteria (5). Dietary selenium in the intestinal villous tip is considered a daily modulator of cytochrome P450-dependent metabolism of drugs and toxins absorbed by intestinal mucosa (6). Villous atrophy occurs in HSES (2).

The procoagulant activity of mononuclear cells (MNCs) may play an important role in the disseminated intravascular coagulation seen in septic shock. This study compares the capacity of Escherichia coli (E. coli) and recombinant human TNF-alpha (rhTNF-alpha) to induce procoagulant activity by baboon MNCs. In vivo studies showed that MNC procoagulant activity was significantly increased at T + 120 min after LD100 E. coli infusion into baboons. Most of this procoagulant activity was attributable to tissue factor. In contrast, a bolus infusion of rhTNF-alpha (150 micrograms/kg) and a monoclonal antibody to activated protein C (2 mg/kg) did not induce any increase of MNC procoagulant activity at T + 120 min even though the plasma TNF-alpha level was 10 times higher than that seen following infusion of E. coli. In vitro studies showed that E. coli at concentrations comparable to that observed in the vivo study and LPS at a concentration of 2.5 ng/mL induced more intense tissue factor expression by both human and baboon monocytes than rhTNF-alpha in the concentrations ranging from 10 to 1,000 ng/mL. These results suggest that TNF-alpha alone is not sufficient to induced noticeable MNC procoagulant activity, at least, in the early stage of this septic shock model.

We present a case of emphysematous pyelonephritis (EPN) with sepsis and disseminated intravascular coagulation (DIC). An 87-year-old man with a history of uncontrolled diabetes mellitus (DM) for more than 25 years was admitted to our hospital for altered mental status and high fever. The initial diagnosis was acute pyelonephritis based on the findings of pyuria and right costovertebral angle knock pain. DIC developed rapidly even though empirical antimicrobial therapy had been started immediately. The abdominal CT revealed the presence of gas in the right renal parenchyma; the definitive diagnosis was EPN. Escherichia coli (E. coli) was identified from both blood and urine cultures. We selected medical conservative therapy with antibiotics because of his advanced age and a history of myocardial infarction three months previously. With only noninvasive therapy and no surgical therapy, his condition improved and he was discharged four months after admission. EPN is a rare, severe gas-forming, necrotizing infection of the renal parenchyma and surrounding areas. Over 90% of the cases occur in DM patients and the most common causative organism is E. coli (60%). The mortality rate with only medical conservative therapy is approximately 20% and transurethral and/or percutaneous drainage or nephrectomy are generally reported to be necessary. To our knowledge, no case with EPN over the age of 84 years has been reported. Although his condition was very severe on admission and long-term antimicrobial therapy was necessary, he was ambulatory at the time of discharge. Herein, we report the pertinent EPN literature and discuss the management of EPN.

This study was conducted to evaluate alterations in coagulation parameters in dairy cows affected with acute Escherichia coli (E. coli) mastitis and to compare those values to cows affected with Staphylococcus aureus (S. aureus ) mastitis. Twenty-four, adult Holstein-Friesian dairy cows affected with acute E. coli mastitis and 17 cows affected with S. aureus mastitis were studied. Cows affected with E. coli mastitis had significantly prolonged activated partial thromboplastin time (APTT) (P < 0.01), prothrombin time (PT) (P < 0.05) and decreased (P < 0.05) platelets numbers. Cows with S. aureus mastitis had only significantly prolonged APTT (P < 0.05) and decreased (P < 0.05) platelet counts. In the hematology evaluation, cows affected with E. coli and those affected with S. aureus mastitis had elevated hematocrit values but only significantly (P < 0.05) so in mastitic cows caused by E. coli. Both groups of mastitic cows had significantly (P < 0.05) lower leukocyte counts. Only cows with E. coli mastitis had significantly (P < 0.05) lower neutrophil count. In the plasma biochemical evaluation, creatinine concentrations were significantly (P < 0.05) elevated in both groups of cows. Blood urea nitrogen (BUN) concentration was only significantly elevated in cows affected with E. coli mastitis. Results of this study indicated that dairy cows affected with acute E. coli mastitis are more likely to develop clinical manifestations of disseminated intravascular coagulation than cows affected with S. aureus mastitis.

An outbreak of enterohemorrhagic Escherichia coli (EHEC) occurred in Toyama and other prefectures in Japan during 2011. Some patients, including adults, showed complications such as encephalopathy, disseminated intravascular coagulation, and hemolytic-uremic syndrome, and the disease course was extremely aggressive. This report describes the clinical features of four patients infected with Escherichia coli (E. coli) O111 who developed very severe to fatal complications. The initial symptoms in all patients included abdominal pain, diarrhea, and bloody stools, and neurological abnormalities started to appear from 1 to 3 days after admission. Vomiting and pyrexia developed in three patients. Leukocyte counts, lactate dehydrogenase (LDH), and fibrin/fibrinogen degradation products were elevated, and thrombocytopenia was evident. Extremely elevated LDH and severe thrombocytopenia were characteristic at the time encephalopathy became apparent. All patients received oral fosfomycin, intravenous antibiotics, and anticoagulant therapy, three received gamma globulin, plasma exchange, and blood transfusion, and two received steroids and dialysis. Three patients required mechanical ventilation, and two adult patients died. E. coli O111 positive for Shiga toxin 2 was detected in stool culture in two patients, and serological tests for E. coli O111 were positive in the other two patients. In conclusion, EHEC O111 can cause severe illness in children and adults, and the prognosis becomes poorer as the severity of complications increases. Close monitoring including platelet counts and LDH are useful. Once these clinical parameters change, intensive treatment should be provided to prevent the development of severe complications.
