In 26 infants and children with septicemia or bacterial meningitis, significantly elevated plasma levels of elastase-alpha 1-proteinase inhibitor (E-alpha 1-PI) were present at time of recognition of infection, even in those patients with neutropenia (range of reference values: 25 to 190 micrograms/L, n = 142; patients: 444 to 2049 micrograms/L, n = 26). After initiation of therapy, normalization of E-alpha 1-PI levels was observed in all patients who recovered from infection. In addition, 18 of 19 children with bacterial meningitis had increased cerebrospinal fluid concentrations of E-alpha 1-PI above the range of normal (range of reference values: 0 to 39 micrograms/L, n = 62; patients: 30 to 3490 micrograms/L, n = 19); concentrations of E-alpha 1-PI in bacterial meningitis were significantly increased when compared with those in aseptic meningitis (range 25 to 194 micrograms/L; n = 15). In 30 patients with local bacterial infections (pneumonia, urinary tract infections, etc.), E-alpha 1-PI was also elevated. These data suggest that E-alpha 1-PI is a sensitive indicator of systemic and local bacterial infection in childhood.

Intra-abdominal sepsis most frequently follows penetrating or blunt abdominal trauma or perforated appendicitis or diverticulitis. The initial leakage of the endogenous gastrointestinal microflora into the peritoneal cavity results in peritonitis and secondary septicemia, which is frequently followed by localized intra-abdominal abscess. These infections are most frequently polymicrobial and relate directly to the unique endogenous microflora at the various levels of the gastrointestinal tract. The treatment of intra-abdominal sepsis is primarily centered around prompt, appropriate surgical intervention. Parenterally administered antibiotics are also required to decrease the chance of local bacterial infection or septicemia. The choice of the appropriate agent(s) to be used initially, before the results of culture and sensitivity reports are available, depends primarily on the clinical presentation and also on whether the intra-abdominal infection occurred in the community or within the hospital setting. Clinical and experimental studies of intra-abdominal sepsis have largely stressed the use of antibiotic agents that have a spectrum of activity effective against the aerobic coliforms and anaerobic Bacteroides fragilis.

Serial quantitative measurements of C-reactive protein (CRP) were performed, using an automated enzyme immunoassay method, in 127 neonates (114 premature and 13 full-term) classified in three groups: neonates with a normal postnatal course (group 1, n = 69), neonates with clinical suspicion of bacterial infection but with negative cultures (group 2, n = 49), and neonates with proven bacterial infection (group 3, n = 9). A total of 545 serial serum CRP concentrations were determined. In group 1, CRP concentrations were below the detection limit of the method (10 mg/L) except in one neonate who suffered from neonatal anoxia but whose clinical course was uncomplicated (CRP: 31 mg/L within 24 h of life). Thirty-three neonates of group 2 had CRP values consistently below 10 mg/L while 16 had elevated CRP concentrations at least on one occasion ranging from 10 to 70 mg/L. Diagnoses other than bacterial infection could explain the raised CRP concentrations in neonates of group 2. CRP concentrations were found to be elevated (greater than 80 mg/L) during the course of infectious diseases in all neonates with proven bacterial infection (septicemia (4), pneumonia (1), multiple micro-abscesses (1), urinary tract infection (3]. Serial measurement of CRP concentrations are shown to be valuable in detecting bacterial infection in neonates as well as in following the efficacy of antimicrobial therapy.

We performed a prospective, controlled study of kinetic therapy in acute, severe stroke. This therapy involved continuous mobilization of a bedridden patient by means of a specially designed rotating bed. All patients with acute stroke presenting to the Neurology Service over an 18-month period were screened, and those that qualified were assigned to confinement in either a routine hospital bed or a rotating bed. We found that the most common complication of stroke with bed confinement of 4 days or longer was bacterial infection consisting of either pneumonia, sepsis, or urinary tract infection. The two variables found to be of greatest significance in affecting the rate of infection were length of bed confinement, especially for greater than 13 days (2.3-fold increased risk, p less than 0.04), and placement in a routine hospital bed (2.9-fold increased risk, p = 0.023).

Posttraumatic acute cholecystitis is an often unrecognized and potentially fatal complication seen among patients hospitalized for trauma, and differs in etiology from cholecystitis which develops de novo. The cause, although not yet clearly defined, is believed to be related to bile stasis, ischemia, bacterial infection, sepsis, the activation of factor XII, and the Shwarzman reaction. A case is described in which a 53-year-old man with pelvic fractures developed acute acalculous cholecystitis and died of multiple organ failure 3 weeks following cholecystectomy. The histopathological findings are also reported; these are most likely attributed to the Shwarzman reaction or the activation of the factor XII pathways. There has been a tendency to regard posttraumatic acute acalculous cholecystitis as induced by trauma, and calculous as mere coincidence. We believe, however, that it is not calculous but histopathological findings that determine whether acute cholecystitis following trauma was more than coincidence or just mere coincidence. Although progress in clinical care has improved the chances of survival of severely traumatized patients, posttraumatic acute cholecystitis has been increasing in frequency. We cannot be careful enough in judging the relationship of this fatal complication to the initial trauma.

Immunosuppressed burned patients receiving antibiotics for suppression of bacterial infection are ideal hosts for opportunistic fungi. Massive excision of burns with autograft and homograft coverage has radically changed the course of disease. Three hundred ninety-three patients were admitted to the Shriners Burns Institute, of whom 125 patients had fungus cultured during their hospitalization and 42 patients subsequently developed involvement of three or more organs. Twenty-one of the 42 patients developed Candida septicemia requiring amphotericin B or flucytosine therapy. The mean third-degree burn in patients with Candida septicemia was 65% total body surface area compared to three-organ involvement/no clinical sepsis at 38% mean third-degree burn. Patients developing candidemia did so during the first week postburn and 7 days after excision therapy. It is hypothesized that massive burns with immunosuppression are further suppressed by repeated surgical intervention, anesthesia, and perioperative use of broad-spectrum antibiotics, further predisposing these patients to early development of Candida septicemia. With early recognition of burn wound invasion by routine biopsies, wound swabs, and early amphotericin therapy, the mortality has been reduced to 14% compared to 60-90% reported in other series.

A retrospective analysis was performed of 109 previously well infants younger than 4 weeks of age with a history of fever who were evaluated for sepsis in an emergency department. The objective was to assess whether infants who were afebrile at the time of evaluation were at similar risk for serious bacterial infection compared with infants with documented fever at the time of evaluation. Of 109 infants evaluated 54 were afebrile and 55 had fever (rectal temperature, greater than 38 degrees C). Serious bacterial infection occurred in 8 (14.5%) infants with documented fever and in none of those who were afebrile at the time of presentation (P = 0.003). An initial complete blood count profile of the two groups showed that nearly all (96%) in the afebrile group had a complete blood count differential ratio [% of lymphocytes + % of monocytes)/(% of polymorphonuclear leukocytes + % band forms] of greater than 1, whereas the majority (87.5%) of febrile infants with serious infection had a differential ratio of less than 1. The neonate with a history of fever who is afebrile upon presentation should receive a complete evaluation for possible bacterial infection. The neonate who appears well, has no focal source of infection on examination and whose laboratory data do not reveal any abnormality represents a low risk for serious bacterial infection.

This case illustrates a unique clinical presentation of primary systemic amyloidosis, namely, overwhelming pneumococcal sepsis. Although there exists a well-established association between hyposplenism and overwhelming bacterial infection, amyloid replacement of the spleen as a primary cause of the hyposplenism has not been reported. Functional hyposplenism in regard to the effect of the spleen on erythrocytes has been reported in cases of diffuse splenic amyloid infiltration. The patient described had a fulminant course and associated disseminated intravascular coagulation, two clinical features more commonly seen in pneumococcemia occurring in asplenic patients as opposed to patients with normal splenic function. He had no predisposing factors, other than amyloid replacement of the spleen, to account for the development of overwhelming pneumococcemia. The immunologic function of the spleen in protection against overwhelming bacterial infection is briefly discussed.

Antiserum against Escherichia coli J5, a "rough" mutant of E. coli 0111, has been reported to confer broad-spectrum protection against serologically unrelated gram-negative bacteria. In order to re-evaluate these findings, we examined the influence of rabbit antiserum against E. coli J5 on the phagocytosis of heterologous gram-negative bacteria by rabbit granulocytes in vitro and its ability to protect mice against gram-negative bacterial infection. In vitro, J5 antiserum enhanced the phagocytosis of E. coli 0111, E. coli 06 and Serratia marcescens 06/014:H2 when compared to normal rabbit serum. However, J5 antiserum did not enhance the phagocytosis of Klebsiella pneumoniae type 2 and Pseudomonas aeruginosa serotype 9. In vivo, the protective effect of J5 antiserum against lethal gram-negative infection was not superior to that of normal (pre-immune) serum with the exception of E. coli 0111 septicemia. In contrast, type-specific antiserum against each of the smooth gram-negative bacteria markedly enhanced phagocytosis in vitro and exerted significant protection in vivo. Thus, in this study antiserum against E. coli J5 proved to be of limited value for opsonization of gram-negative bacteria and protection against gram-negative bacterial infection.

We have followed 46 children with acquired immunodeficiency syndrome and acquired immunodeficiency syndrome-related complex. Twenty-six patients had at least one episode of serious bacterial infection. Twenty-seven episodes of sepsis were documented in 21 patients. Soft tissue infection was common in both the presence and the absence of documented bacteremia. Urinary tract infection commonly presented as worsening diarrhea in the absence of sepsis. Organisms commonly isolated included Streptococcus pneumoniae, Haemophilus influenzae and Salmonella sp. Staphylococcal infection accompanied episodes of cellulitis/abscess. Escherichia coli commonly caused urinary tract infection in the absence of sepsis. Enteric and nosocomial sepsis was limited to hospitalized, instrumented patients or to individuals who had received prior antibiotic therapy as outpatients. We conclude that bacterial infection causes serious morbidity in acquired immunodeficiency syndrome and acquired immunodeficiency syndrome-related complex and may be further evidence for altered humoral immunity in the disorder.
