Underlying diseases, complications, clinical findings, and laboratory findings were evaluated in 158 cases of septicaemia admitted to Jikei University Hospital from 1975 to 1994, in order to conjectured factors that prescribe for the prognosis. 50% of the patients had underlying diseases. Malignancy including leukaemia (31 cases, 39.2%) was the most common underlying disease, followed by low birth weight infant (17 cases, 21.5%), aplastic anemia (9 case, 11.4%), and congenital heart disease (7 cases, 8.9%). The death rate for patients with underlying disease (27.8%) was significantly greater than the mortality for normal patients with septicaemia (8.9%) (p < 0.05). Meningitis (24.7%) was the most common complication, followed by DIC (19.6%), shock (15.2%), and pneumonia (10.8%). The mortality rate of septicaemia complicated by shock was 66.7% (p < 0.01), and that complicated by DIC was 45.2% (p < 0.01). The mortality rate for patients with the clinical findings of respiratory distress, cough, abdominal distention, cyanosis, splenomegaly, or peripheral coldness was more than 40% and significantly greater (p < 0.01). Mortality rate in patients with granulocyte counts of < 4.000/mm3, platelet counts of < 5 x 10(4)/ mm3, total protein of < 5.0 g/dl, or ESR of < 20 mm/hr were significantly greater (p < 0.01) than those in patients with normal laboratory findings. Coincidence rate of blood and stool cultures was 57.9% for E. coli, and 28.6% for Klebsiella sp., and that of blood and throat cultures was more than 30% for Pseudomonas sp., Haemophilus influenzae, and Staphylococcus aureus. In the study of antimicrobial susceptibility for microorganisms isolated, the number of drug resistant S. aureus had increased in the last 10 years.

Capnocytophaga canimorsus, formerly designated Dysgonic fermenter 2 (DF-2) was first described in 1976; it is a commensal bacterium of dogs and cats saliva, which can be transmitted to man by bite (54% of cases), scratch (8.5%), or mere exposure to animals (27%). We present a review of the clinical and microbiological characteristics of the Capnocytophaga canimorsus infections and 12 cases of infection in France. Over 100 cases of human infections have been reported, mainly septicemia in patients with diminished defences, due to splenectomy (33%), alcohol abuse (24%), immunosuppression (5%). However 40% of septicemia occur in patients with no predisposing conditions. Other infections are less frequent: meningitis, endocarditis, arthritis, pleural and localized eye infections. These infections range from mild to fulminating disease, with shock, respiratory distress, disseminated intravascular coagulation. Dermatological lesions (macular or maculopapular rash, purpura) or gangrene are common. This fastidious Gram-negative bacterium grows slowly on chocolate agar or on heart infusion agar with 5% rabbit blood incubated in 5% CO2. In spite of a great susceptibility of bacteria to antibiotics, the mortality is of 30%. Because of the severity of these infections, taking into account this organism in the management of bites is necessary, especially in patients with predisposing factors.

Changes of endotoxin in plasma, and the response of the coagulation system and blood cells in septicemia of Haemophilus parasuis infection were examined by inoculation with H. parasuis in specific pathogen-free (SPF) pigs. Eight pigs were inoculated intratracheally with 10(5), 10(6) and 10(7) colony formation units (CFU) of the strain Nagasaki (serovar 5). All pigs died 28 to 42 hr after inoculation. Haematologically, severe leukopenia occurred 24 hr post inoculation (hpi) until death. Glucose concentration decreased from 24 hpi to death. In the coagulation system, decrease of platelet counts, prolongation of prothrombin time, activated partial thromboplastin time, and increase of fibrinogen-fibrin degradation products were observed in all inoculated pigs. Endotoxin was detected in the plasma of all the inoculated pigs from 16 hpi to death, and its concentration rose dramatically just before death. H. parasuis was re-isolated from the blood of all inoculated pigs from 16 hpi to death, and also from almost all organs and body fluids of the pigs. The pigs had microthrombi in the kidney, liver and lungs, and many also had pneumonia, meningitis and serositis. H. parasuis antigen was detected in the lesions by the immunoperoxidase technique. The results indicated that disseminated intravascular coagulation (DIC) and endotoxin shock involved aggravation of clinical signs and death on the pigs induced to septicemia of H. parasuis.

Meningococcal disease is an infection caused by Neisseria meningitidis, a gram-negative diplococcus that is the leading cause of bacterial meningitis in children and young adults in the United States, with an estimated 2,600 cases reported each year. N. meningitidis infection rates are highest in children 3 to 12 months of age. Four distinct clinical situations are associated with meningococcal infection. The most common is asymptomatic nasopharyngeal colonization. Benign bacteremia is discovered in the absence of classical clinical findings of meningococcemia, but blood cultures are positive for N. meningitidis. Meningitis, the most common pathologic presentation, is associated with fever, headache, and nuchal rigidity. The mortality rate is about 5% in children and 10% to 15% in adults. Meningococcemia, the most severe form of infection, may involve petechial rash, hypotension, and disseminated intravascular coagulation. It is a fulminant condition that can, if untreated, progress from initial symptoms to coma and death in 12 to 48 hours. Spread of these endemic cases can be controlled by administering prophylactic antibiotics to close contacts of patients.

Dog bites may result in serious bacterial infections with e.g. the gram-negative rods Capnocytophaga canimorsus and Pasteurella multocida. Human disease caused by these microorganisms can be complicated by acute development of septicaemia and/or meningitis followed by disseminated intravascular coagulation syndrome, peripheral gangrene and renal failure. The mortality of C. canimorsus septicaemia is about 23-31%. These severe infections are most often reported in immunocompromised patients and occur a few days after the bite. By reviewing the literature it is concluded that the broadest prophylactic coverage is obtained by amoxicillin/clavulanic acid and that antibiotic prophylaxis should be given to all immunocompromised patients experiencing a dog bite. Moreover, prophylactic treatment should be initiated for all patients with greater penetrating wounds and those involving the hands.

Seventy-seven patients with Gram-negative bacillary meningitis (GNBM), 57 males and 20 females, aged 17-86 years, were identified at Kaohsiung Chang Gung Memorial Hospital, over an 11-year period. Fifty-four infections were community-acquired, and 23 were nosocomial; 49 were spontaneous and 28 occurred after head surgery or neurosurgery. The organisms most frequently involved were Klebsiella pneumoniae, Pseudomonas aeruginosa, Escherichia coli, and Acinetobacter. Rarer pathogens included Citrobacter species, Serratia marcescens, Enterobacter cloacae, and Proteus mirabilis. All patients who did not receive appropriate antibiotic therapy died. The mortality in those treated with appropriate antibiotics was 28%. Other statistically significant prognostic factors included septic shock, initial level of consciousness, hyperosmolar hyperglycemic nonketotic coma, disseminated intravascular coagulation, high cerebrospinal fluid lactate levels and leucocytosis. In the multiple logistic regression analysis, only appropriate antimicrobial therapy and septic shock were strongly associated with mortality even after adjusting for other potentially confounding factors. Despite the high mortality, management can be improved by early diagnosis, early use of appropriate antibiotics, and correction of underlying and associated medical derangement.

The clinical manifestations and course of meningococcal disease have been well described, but atypical presentations may, if unrecognized, lead to a delay in treatment. We describe here an unusual case of this disease in a 21-y-old woman who presented with an acute rigid abdomen, clinical and laboratory features of sepsis, shock and early DIC with no indication of meningococcal infection. She developed a rapidly spreading purpuric rash, conjunctival haemorrhages, hypotension and tachycardia and a low urine output. Laboratory investigations showed a low platelet count, low haemoglobin and normal WBC. A presumptive diagnosis of meningococcal septicaemia was made and recovery followed treatment with cefotaxime, fluids and inotropes. A fully sensitive Neisseria meningitis Group C, type 2a, subtype NT was isolated from blood cultures, but not from CSF obtained after antibiotic treatment.

A 39-year-old female, who had splenectomy for idiopathic thrombocytopenic purpura (ITP) in 1988, was admitted to our hospital with high fever, headache, and loss of consciousness on November 29,1997. Neck stiffness and Kernig's sign were present. Examination of cerebrospinal fluid showed pleocytosis up to 506 cells/mm3 with 89% of polymorphonuclear cells and elevated protein to 1,135 mg/dl, and absence of glucose, Streptococcus pneumoniae phagocytosis was detected in the fluid. We diagnosed her as having pneumococcal meningitis as overwhelming postsplenectomy infection (OPSI) syndrome. After administration of dexamethasone (8 mg/day), cefotaxime (4 g/day), and ampicillin (6 g/day), she survived without any complications. Splenectomized patients have been recognized as immunocompromized hosts, and carry high morbidity and mortality risk from fulminant bacterial infections. Therefore, emergency treatment is important to reduce high mortality in such infections. We present an adult case of OPSI syndrome which occurred as pneumococcal meningitis, and we would like to emphasize the importance of prompt use of corticosteroids and high dose of sensitive antibiotics before DIC may occur during the course of illness.

A previously healthy 16-month-old Korean girl with symptoms of fever, vomiting, and generalized tonic seizure was diagnosed to have Group D non-typhoid Salmonella meningitis. The patient was treated with ceftriaxone (100 mg/kg/day) and amikin (22.5 mg/kg/day) initially and ciprofloxacin (30 mg/kg/day) was added later because of clinical deterioration and disseminated intravascular coagulation. Brain CT performed on the second day showed a well-demarcated low density lesion in the right lentiform nucleus and both caudate nuclei, without evidence of increased intracranial pressure. MRI performed on the 11th day confirmed CT scan findings as well as right subdural fluid collection, brain atrophy, and ventriculomegaly. She underwent subdural drainage and later ventriculo-peritoneal shunt operation. Despite receiving intensive treatment, she still has severe neurologic sequelae. Our case shows that infarctions of basal ganglia and thalami are not specific for tuberculous meningitis and that meningitis complicated by infarction is indicative of grave prognosis.

A 60 year-old female who had never been seriously ill, was brought to the emergency ward after she had been found somnolent at home. She developed renal failure, meningitis, respiratory distress and disseminated intravascular coagulation. Overwhelming septicemia was evident, and streptococcus pneumoniae was isolated from blood and cerebrospinal fluid. Surprisingly, peripheral blood smears showed numerous Howell-Jolly-bodies, indicating severe impairment of splenic function. On abdominal ultrasound, CT-scan, and scintigraphy no spleen could be detected. There was no history of abdominal surgery. Apparently, congenital asplenia, which was not noticed until the age of 60, was responsible for the patient's life-threatening septicemia. We suggest that, in cases of severe septicemia, the examination of a blood smear is useful to detect functional (or congenital) asplenia.
