Twenty-four fatal cases of echo 11 infection in the eleven years 1968-78 are presented. All were children, and could be divided into two groups according to age at death and clinical presentation. The first group comprised 12 babies who died aged between 5 and 11 days after a short illness characterised by collapse, acidosis, and bleeding. At necropsy there was evidence of disseminated intravascular coagulation with haemorrhage into many organs including the renal medulla, suprarenal glands, gastrointestinal tract, and central nervous system. Six cases showed hepatic necrosis which was massive in three. Virus was present in many tissues. Infection was probably acquired from the mothers at delivery in 3 cases. Low maternal neutralising antibody titres and prematurity were thought to be adverse factors in the outcome. The second group consisted of 12 children aged between 9 weeks and 4 years 10 months who died suddenly. Pathological findings included upper respiratory tract infection, pneumonia, encephalitis, and gastroenteritis. Six of this group had been classified as 'cot deaths'. The role of echo 11 in the death of some of these older children is unknown. This report shows the danger of echo 11 to neonates, especially if unprotected by maternal antibody.

Fatal Mycoplasma pneumoniae infection in a 30-yr-old woman is described. After 9 days of symptoms, the patient developed severe respiratory distress, rapidly progressive pneumonia, cardiovascular collapse, and acute renal failure. Death occurred 24 h after hospital admission. Postmortem examination demonstrated a diffuse membranous laryngotracheobronchitis, massive bilateral pneumonia, disseminated intravascular coagulation with widespread renal involvement, and hemorrhagic necrosis of the adrenal glands. Mycoplasma pneumoniae was isolated from the trachea, lungs, kidney, and brain, indicating hematogenous dissemination of the organism from its portal of entry in the respiratory tract.

22 patients with severe preeclampsia-eclampsia were treated in our Intensive Care Unit from 1972 to 1978. Control of convulsions was achieved by diazepam, diphenylhydantoin and phenobarbital. In 11 comatose patients brain monitoring was carried out by frequent neurological examination and use of computerized x-ray tomography; aspiration of gastric contents was prevented by nasotracheal intubation. Brain oedema therapy included controlled hyperventilation, steroids and mannitol (7 patients). 10 patients with respiratory failure (due to pulmonary oedema, "shock lung" or aspiration pneumonitis) were treated by mechanical ventilation. Diastolic blood pressure above 100 mm Hg was reduced by hydralazine. Diuresis was induced by normalization of hypovolaemia with albumin and plasma expanders. Six patients died (27%); main causes of death included intracerebral haemorrhage, brain oedema, heart failure, acute pulmonary thromboembolism and bleeding from DIC.

A therapeutic trial of transfusions with polymorphonuclear leukocyte concentrates was performed in newborn infants with bacterial sepsis proven by blood culture. With each transfusion, 20 ml/kg of a preparation obtained by continuous flow filtration leukapheresis, and containing 0.5 to 1 x 10(9) WBC, with less than 6% lymphocytes, was administered. Twenty newborn infants with sepsis received from 2 to 15 PMN transfusions. Results were compared with findings in 18 newborn infants with sepsis admitted during the trial period, and not treated because of unavailability of the PMN preparation (Group B). Infants with fulminant illness were excluded from both groups. Groups A and B were similar with respect to clinical characteristics and to etiology (in the majority cases a highly antibiotic-resistant Klebsiella). The mortality rate was significantly lower in Group A than in Group B in the whole series (10% vs 72%, P < 0.001), and also in the subgroups with birth weight equal or below 1,500 gm (10% vs 91%, P < 0.001). Major complications and associated conditions (i.e., necrotizing enterocolitis, meningitis, pneumonia, peritonitis, osteoarthritis, disseminated intravascular coagulation) were observed in 12 patients of Group B, and in only three infants of Group A. Untoward effects attributable to PMN transfusions were never observed. PMN transfusion was a highly effective therapeutic tool in our population of infected newborn infants.

We examined the kinetics of tumor necrosis factor (TNF) production induced by Escherichia coli lipopolysaccharide (LPS) in relation to LPS tolerance and endotoxemic lesions of piglets. The plasma of piglets demonstrated cytotoxicity to TNF-sensitive L929 cells between 0.5 and 4 h after inoculation with 200 micrograms kg-1 of LPS. This cytotoxicity was neutralized by anti-bovine TNF serum. These piglets had disseminated intravascular coagulation (DIC) and meningoencephalitis. However, if piglets were first treated with three doses of 40 micrograms kg-1 of LPS, both TNF production and the occurrence of DIC were inhibited when 200 micrograms kg-1 of LPS was inoculated into these piglets. Repetitive inoculation with increasing doses of LPS induced fibrinoid vasculitis, meningoencephalitis and pneumonitis, while hemorrhage was minimal. A very low amount of TNF activity was detected from most of the samples of a piglet after repeated LPS inoculation. These results suggested that severity of the hemorrhagic and thrombotic lesions might relate to the amount of endogenous TNF activity, and that LPS tolerance might relate to inhibition of TNF production.

This report outlines our experience with streptococcal toxic shock syndrome (STSS) at the Veterans General Hospital-Kaohsiung during the period October 1990 to November 1993. Group A streptococci were isolated from blood or normally sterile tissue in association with hypotension and multi-organ failure in the eight cases studied. A primary focus of infection was identified in seven cases, including pneumonia (1), septic arthritis (1) and soft-tissue infections (5). The remaining patient suffered from hyperglycemic hyperosmolar non-ketotic coma and Group A streptococcal bacteremia, without an obvious focus of infection. There were four cases of bacteremia. Clinical complications included acute renal failure in all eight cases, disseminated intravascular coagulation in five cases, liver involvement in two cases, adult respiratory distress syndrome in one case and soft-tissue necrosis in five cases. All isolates were sensitive to penicillin, and most patients were treated with intravenous penicillin G, with or without other antibiotics (gentamicin or clindamycin). Of the six patients with soft-tissue infection, two underwent amputation of the infected limb, and one patient underwent sono-guided pigtail drainage of psoas muscle abscess. Three of the patients died. STSS may be uncommon in Taiwan, but it is not rare. Early recognition of STSS (facilitated by Gram stain and culture), prompt debridement and drainage, and adequate antibiotic treatment with penicillin or clindamycin, or both, are necessary for control of such lethal infections.

The aims of this retrospective study were to review the frequency and patterns of bacterial sepsis in children infected with human immunodeficiency virus. The charts of 233 human immunodeficiency virus-infected children cared for during a 10-year period in 4 tertiary hospitals in Madrid were reviewed. There were 43 episodes of sepsis in 31 (13%) children. Twenty of them had acquired immunodeficiency syndrome, 10 were class PA2 and 1 was class P1B. The most common organisms recovered were: nontyphoidal Salmonella, 10 cases (23%); Streptococcus pneumoniae, 9 cases (21%); Staphylococcus epidermidis, 6 cases (14%); Escherichia coli, 5 cases (12%); Enterococcus faecalis, 4 cases (9%); Campylobacter jejuni, 2 cases (5%). In 28 episodes of bacteremia there were other sites of associated infection: pneumonia, 6 cases; urinary tract infection (UTI), 5 cases; gastrointestinal disease, 4 cases; catheter-related bacteremia, 12 cases. Eight patients had more than 1 episode of bacteremia. The rate of complications was high: 6 children had septic shock; and 2 of them developed disseminated intravascular coagulation. There was 1 death directly related to sepsis.

Twenty-eight alcoholic patients with community-acquired pneumonia who were admitted to a referral medical center during a 3-year period were reviewed. All were men and with few exceptions were heavy smokers. The overall mortality was 64.3%. The most dramatic group was that of 11 patients (39.3%) with bacteremic Klebsiella pneumoniae pneumonia (BKPP), which had high mortality rate (100%), short onset of illness before hospital admission (42.6 +/- 8.2 h, mean +/- SD), and short survival time after the admission (24.6 +/- 7.9 h). All these 11 patients needed intensive care unit (ICU) management and ventilatory support. ARterial blood gas values showed marked hypoxemia and metabolic acidosis in most of these 11 patients, and presence of shock at arrival in the hospital was noted in 8 patients. Acute renal failure and disseminated intravascular coagulation developed in six patients. Chest radiographs showed pleural effusion and radiographic spread in nearly 50% of patients. Combination chemotherapy consisting of one aminoglycoside and one second- or third-generation cephalosporin was initiated in all patients. The rapidly fatal outcome of these 11 patients with BKPP despite management with adequate antibiotics and intensive care indicated the fulminant nature of this disease. High virulence of the microorganism, altered immune response, and increased susceptibility to infection may all have contributed to the fulminancy in this group of patients. The disease continues to present many difficulties in management.

Endotoxin(lipopolysaccharide = LPS), cell wall component of gram-negative bacteria, activates monocytes and macrophages to release cytokines, reactive nitrogen intermediates (RNI), and to generate tissue factor(TF) which initiate coagulation. We have purified 7kDa and 18kDa cationic antibacterial proteins (CAP-7 and CAP-18) with LPS-binding and LPS-neutralizing activities from rabbit granulocytes using as an assay the agglutination of erythrocytes coated with Re-LPS. From protein sequencing, CAP-7 was identified as the C-terminal 37 amino acid fragment of CAP-18. Synthetic peptide #197 (identical sequence to CAP-7, Gly1-Try37) and #36-1 (a truncation of CAP consisting of 32 amino acid residues, Gly1-Ala32) showed LPS-binding activity. Each peptide inhibited LPS-induced tissue factor(TF) generation by murine peritoneal macrophages, even added 1-3 hours after stimulation of cells with LPS. C57BL/6 mice treated with #197 were significantly protected from lethal LPS challenge. Peptide #36 also blocked the LPS-induced lethality. These peptides had antibacterial activity to gram-negative bacteria, such as E.coli, S.typhimurium, K.pneumonia, Ps.aeruginosa and also to gram-positive S.aureus (Methicillin sensitive and resistant strains). Both peptides inhibited TF- and Xa-induced plasma clotting. Using synthetic chromotogenic substrates, both CAP7 peptides blocked the coagulation cascade at two sites, activation of factor X to Xa and conversion of Factor II (prothrombin) to factor IIa (thrombin). In vivo treatment of peptide #197 prevented acute lethality in mice injected with tissue factor (rabbit brain thromboplastin). Two other peptides, #32(Gly1-Phe9) and #50(Ile13-Typ37) failed to demonstrate LPS-binding, LPS-neutralizing, antibacterial and anticoagulant activities. The active peptides but not the inactive peptide maintain a putative heparin binding domain at their N-termini. This heparin binding domain is participate in the LPS-binding, LPS neutralizing, antibacterial and anticoagulant activities of CAP7. These active peptides may have a therapeutic potential for treatment for DIC due to sepsis and endotoxin shock.

Varicella, usually a benign infection of childhood, is known to be associated with more serious complications, especially in adults and immunocompromised patients. Of these, varicella pneumonitis is the most common. Primary varicella hepatitis has been described, though rarely, in immunocompromised patients. We present a case of a previously healthy human immunodeficiency virus-negative 26-year-old immigrant from El Salvador in whom primary varicella developed that rapidly progressed to fulminant hepatic failure, disseminated intravascular coagulation, and death. Autopsy revealed evidence of varicella in the liver, adrenal glands, and myometrium. To our knowledge, this is the first report of a fatal case of varicella hepatitis in a previously healthy, immunocompetent patient.
