Overwhelming sepsis is rarely complicated by secretory diarrhea. We present a case of fulminant sepsis associated with dermatologic manifestations, disseminated intravascular coagulation (DIC), and a severe secretory diarrhea that has not previously been described. This followed a dog bite, and the patient was otherwise healthy. The combination of septic shock, skin lesions, and DIC occurring after a dog bite has been attributed to dysgonic fermentor 2 organisms, now called Capnocytophaga canimorsus, but none were cultured in this case (7). Dysgonic fermentor-2 may be a new cause of secretory diarrhea and should be considered in the differential diagnosis of overwhelming sepsis associated with diarrhea.

We observed 73 patients with the hemolytic uremic syndrome (HUS) in 9 years (1980-1988), comprising 34% of patients with acute renal failure treated over the same period. There were 53 boys and 20 girls; 59% were below the age of 2 years and 33% between 2 and 5 years. Acute, usually severe dysentery, responding poorly to various antibiotics, was the prodromal illness in 80%, whereas 12% had watery diarrhea. Most patients had severe renal involvement with anuria in 56% and oliguria in 30%. A polymorphonuclear leukocytosis was present in 85% of cases, but had no correlation with the highest levels of blood urea. Coagulation abnormalities suggesting consumption coagulopathy were found in 24 of 30 cases. The results of stool culture showed Shigella species in 7 cases and nontyphoidal Salmonella in 9. Escherichia coli were isolated in 11 cases, but were not further characterized. Renal biopsy showed total or patchy cortical necrosis in 20 of 50 cases. The patients were managed with supportive care, including transfusion of fresh blood or plasma and dialysis as required. The mortality was 60%, being chiefly related to the duration of renal failure and presence of renal cortical necrosis, whereas persistent dysentery and infections were complicating factors. The presence of convulsions and coagulation defects had no relation to the outcome. Our observations indicate that HUS in children in northern India is mostly related to dysentery, likely to be shigellosis, and is usually associated with severe renal damage and a high death rate.

Disseminated intravascular coagulation (DIC) is a frequent complication of meningococcal sepsis in children. The clinical course variability, the severity of manifestations and the need of an early diagnosis for appropriate treatment, guides us to report a case of meningococcal sepsis and DIC. The patient, male, prematurely born, 11 months years old, presented himself with high fever of sudden onset, malaise, diarrhea, diffuse skin rash with abdominal petechiae, and no clinical evidence of meningitidis. Initial hematochemical findings, peripheral leukocytosis, quantitative and qualitative changes in plasma coagulation factors, liquoral hypocellularity together with the development of signs of meningeal irritation (stiff neck and back) were considered diagnostic clues for meningococcal sepsis associated with DIC. A gram-negative diplococcus was cultured from liquor. Primary goals of the treatment of this life-threatening clinical picture were the elimination of the bacterial component, the correction of clotting disorders and careful control of shock and metabolic acidosis often related with DIC. The patient then received a wide spectrum Cephalosporin, fresh frozen plasma, appropriate electrolyte solutions and eventually heparin, which led to a complete control and resolution of symptomatology.

Rabbits were given polyclonal anti-tissue factor (TF) immunoglobulin G (IgG) before an injection of endotoxin to test the hypothesis that TF triggers disseminated intravascular coagulation (DIC) after endotoxin. The rabbits had been prepared with cortisone to develop DIC after one injection of endotoxin. Anti-TF IgG substantially reduced the falls in fibrinogen, factors V and VIII, and platelets noted in control rabbits given preimmune IgG before endotoxin. At autopsy 24 hours later, fibrin was present in glomerular capillaries of 4 of 5 control rabbits, but in none of 11 rabbits given anti-TF IgG. DIC was also induced in a second group of rabbits by the infusion, over 4 hours, of 1 microgram/kg of purified, reconstituted rabbit brain TF. This resulted in striking falls in plasma fibrinogen, factors V, and VIII that were diminished, but not prevented by prior treatment with anti-TF IgG. Circulating activated factor VII, induced by either TF infusion or endotoxin, could not be detected after DIC. Mean plasma extrinsic pathway inhibitor (EPI) activity did not fall significantly after endotoxin, and only to about 65% of the preinfusion after infusion of TF. Thus, DIC induced by both agents proceeded despite nearly normal plasma EPI levels. Because EPI neutralizes factor VIIa/TF in vitro only after a short lag period, the DIC that persisted for up to 6 hours after injection of endotoxin suggests that TF activity continued to be generated during this period on cells to which the circulating blood was exposed. All animals given endotoxin became ill with cyanosis, tachypnea, cold ears, and diarrhea, regardless of whether they had received anti-TF IgG to attenuate DIC. Infusion of TF caused some animals to die acutely with pulmonary arterial thromboses, but surviving animals did not appear ill. The findings support the hypothesis that exposure of blood to TF triggers DIC after endotoxin, but is not important for the pathogenesis of endotoxin-induced shock.

A 20-year-old female presented with sudden onset of abdominal pain, diarrhoea and vomiting progressing to fever, tachycardia and mild hypotension. Within 12 hours, a petechial rash appeared on the face and abdomen, spreading to the extremities. Laboratory findings confirmed the diagnosis of acute meningococcaemia. Clinical features of endotoxic shock, vasculitis and skin necrosis rapidly ensued. Aggressive treatment to control the septicaemia, disseminated intravascular coagulation and unstable cardiovascular state ultimately proved successful. Approximately 6 weeks later, amputation of some of the digits and extensive skin grafting were carried out in the Regional Burns Unit. However, serious psychological side effects gradually began to appear which required urgent psychiatric intervention. For an active young woman the challenge of coping with such a severe illness and coming to terms with the disability and disfigurement resulting from it was almost overwhelming. It was, perhaps, particularly hard because of the threat posed to her ambition to complete her nursing education and become a nurse. Little was found in the nursing literature on acute meningococcaemia. But this illness provides considerable challenges not only to those who suffer from it, but also to those who nurse them. A final brief review of published literature on acute meningococcaemia and the clinical manifestations and outcome of it is provided for those who wish to know more about it.

We treated nine infants who unexpectedly developed shock, seizures, and fever, followed by diarrhea, consumption coagulopathy, and hepatorenal dysfunction. Despite vigorous treatment, three infants died and all except one of the six survivors have severe residual neurologic abnormalities. Postmortem findings included cerebral edema, white matter petechial hemorrhages, gastrointestinal hemorrhages, and fatty liver. These clinicopathologic features are similar to those previously described in 10 infants as being due to hemorrhagic shock and encephalopathy, except for the presence of fatty liver in our patients. Based on the combined experience of 19 infants, we propose diagnostic criteria for hemorrhagic shock and encephalopathy that may facilitate recognition and differentiation from other shock syndromes in infancy.

A previously healthy 35-year-old woman was seen at 37 weeks' gestation with a 10-day history of fever, vomiting, diarrhea and malaise. Serum laboratory findings included elevation of serum bilirubin and AST, prolongation of serum prothrombin time and a positive monospot. A tentative diagnosis of acute fatty liver of pregnancy was made, and a healthy male infant was delivered by emergency cesarean section because of fetal distress. Over the subsequent 3 days, acute progressive oliguric renal failure, disseminated intravascular coagulation, hypoglycemia requiring intravenous dextrose infusion and pancreatitis developed; her mental status progressed to stage III encephalopathy. Quantitative computed tomography estimated the liver volume to be 770 cm3. The decision to proceed with orthotopic liver transplantation was made on the basis of progressive clinical deterioration despite aggressive support and because of her small liver size. After transplant, the patient's multisystem failure rapidly reversed. Histopathological examination of the native liver demonstrated predominantly zone 3 microvesicular steatosis with characteristic ultrastructural changes consistent with acute fatty liver of pregnancy. Southern blot analysis for Epstein-Barr virus DNA was negative. We conclude that orthotopic liver transplantation should be considered for the small group of patients with fulminant hepatic failure associated with acute fatty liver of pregnancy who manifest signs of irreversible liver failure despite delivery of the fetus and aggresive supportive care.

Cholera disease can be induced in the rabbit by duodenal inoculation (DI) of Vibrio cholerae organisms after ligation of the cecum (C) (DIC model). When ligation of the cecum is omitted, no disease symptoms develop. In contrast, the animals are primed which becomes apparent as vibriocidal protection upon challenge with V. cholerae in the DIC model. This protection coincides with high anti-O antigen IgA levels in the bile. The O antigen was shown to be the protective antigen and it must be presented by live organisms. A non-enterotoxigenic mutant of V. cholerae induced protective immunity in the rabbit but was reported to cause mild diarrhea in human volunteers. Looking for alternatives, we applied cholera toxin, known as a mucosal adjuvant, together with killed V. cholerae cells to rabbits. Unfortunately, the minimum adjuvant dose was equal to the minimum toxic dose. A Salmonella typhimurium strain expressing also the V. cholerae O antigen induced systemic rather than local immunity which was not protective. Several Escherichia coli strains were able to elicit a local immune response, but the animal to animal differences were considerable. Therefore, V. cholerae itself was thought to be the most appropriate carrier organism. Some non-enterotoxigenic and auxotrophic mutants of V. cholerae were able to prime and did not show any undesired side-effects in the DIC model. Therefore, further attenuation of non-toxigenic V. cholerae strains by means of stable deletions in nutritional genes seems to be the most promising way to obtain acceptable vaccine candidates.

We experienced 57 episodes of Pseudomonas aeruginosa bacteremia in 55 patients with hematologic disorders in a 16-year period. Ninety-five percent of the patients had hematologic malignancies such as acute leukemia. All but one patient received cytotoxic or immunosuppressive therapy at or prior to the onset of bacteremia. Seventy-seven percent of the episodes occurred during profound granulocytopenia of below 100/mm3. All the patients acquired their infection in the hospital, and 96% had received antibiotic therapy during the preceding two weeks. Periodontal, anorectal, lower respiratory tract, and urogenital infections were the sources of bacteremia in about three-quarters of the episodes. Periodontal infection tended to progress to cellulitis of the face or the floor of the mouth, often resulting in bacteremia of the unimicrobial type, while anorectal infection predisposed to abscess formation, frequently leading to bacteremia of the polymicrobial type. Cellulitis at onset was seen in 35% of the episodes. Most sites of infection did not become apparent until one to three days after the onset of fever, probably because of depressed inflammatory response associated with severe granulocytopenia. The majority of patients complained of gastrointestinal symptoms such as nausea and vomiting, abdominal pain, diarrhea, and abdominal fullness at the onset of bacteremia. Major complications included bacteremic shock (63%), impaired consciousness (25%), ecthyma gangrenosum or hemorrhagic gangrenous cellulitis (18%), and jaundice (12%). Furthermore, there were one case each of endocarditis and disseminated intravascular coagulation. It was thus suggested that the clinical picture of P. aeruginosa bacteremia complicating hematologic disorders is influenced by the predisposing conditions associated with the underlying diseases and their treatment.

Although a 39-year-old male received the curative operation of total gastrectomy for advanced scirrhous carcinoma of the stomach, recurrence of cancer was occurred soon after the surgery, accompanied by hemorrhagic diathesis from DIC. The abdominal CT scan examination revealed the rapid enlargement in the size of the several lymphnodes around the abdominal aorta, and the blood chemistry tests showed marked increase of the serum CEA value. The sequential chemotherapy with intermediate dose of MTX and 5-FU in conjunction with OK-432 was started to treat the case. This chemotherapy was carried out once a week for 5 times and consequently DIC was led to the perfect remission. Furthermore, CEA level decreased within normal range, and the size of the enlarged lymphnodes at paraaortic area diminished remarkably. Although he complained of nausea and loss of appetite during the treatment, no severe adverse effects such as granulocytopenia, diarrhea, or loss of hair were observed. The successful result in this patient suggests that sequential therapy of intermediate dose of MTX and 5-FU with administration of OK-432 may be effective in the treatment of advanced scirrhous carcinoma of the stomach.
