The frequency, causes, clinical and laboratory features, and outcome of febrile episodes in 160 hospitalized patients with systemic lupus erythematosus were reviewed. Eighty-three febrile episodes were identified in 63 patients and were ascribed to active lupus erythematosus alone (60 per cent), infections (23 per cent) and miscellaneous causes (17 per cent). Bacteremia was present in nine of the 19 infectious episodes and resulted in a fatal outcome in a third of the patients. Leukocytosis, neutrophilia, shaking chills and normal levels of anti-DNA antibodies were associated with infection in febrile patients with lupus erythematosus.

Blood samples of 115 patients of both sexes admitted to the hospital with urinary tract infections were examined for bacteremia. Out of 115 patients 12 (10%) had positive blood cultures associated with significant urinary counts (greater than or equal to 10(5) organisms/ml). Although 10% of the patients showed positive blood cultures indicating bacteremia none of them had shaking chills, fever or any other clinical signs of septicaemia. None of the patients from whom blood samples were taken had yet received antimicrobial therapy. Bacterial isolates from urine and blood were identical. Microorganisms most frequently isolated were found in the following order: E. coli, Proteus species, K. pneumoniae and coagulase negative staphylococci. Neoplasms, obstruction of the urinary tract and age were found to be high risk factors.

Two Bactec bottles (aerobic and anaerobic) and one single bottle Signal were used for detecting bacteremia in 405 patients (47 children and 358 adults). The two blood culture Signal and Bactec aerobic were continuous shaking for up to 24 hours. 10.3 p. cent of patients had positive cultures (62.3 p. cent Gram +, aero-anaerobic bacteria). Nine bacteremia were detected by only one system (4 for signal, 4 for Bactec) 77.1 p. cent of 83 strains were positive on the two systems together, but 7.2 p. cent only in the Bactec and 15.6 p. cent only in the Signal. The delay of growth give an advantage to the Bactec (67 p. cent in 24 hours). The advantages and the disadvantages of the two systems were analysed.

An adult mouse (18-20 g) model was developed for studying the pathogenesis of Campylobacter isolates. Iron-loaded BALB/c mice given 10(8)-10(9) Campylobacter colony forming units by intraperitoneal injection developed a severe mucoid diarrhea within 4 h. Severe diarrhea, consisting of unformed stools containing blood, mucus, and fecal leukocytes, persisted for 24 h. Diarrheal symptoms in surviving mice resolved gradually; no diarrhea was observed 5 days after inoculation. Mice not pretreated with iron developed no diarrheal symptoms, and no severe diarrhea was produced in mice inoculated orally. A transient (less than 24 h) bacteremia occurred in mice inoculated either orally or intraperitoneally. Liver, spleen, and kidney were positive for Campylobacter for 48 h; intestinal contents were positive for 5-7 days. Mice given greater than or equal to 10(10) colony forming units showed symptoms of endotoxemia (ruffled fur, inactivity, shaking, tearing, and hypothermia) and died without diarrheal symptoms. Mice given nonpathogenic Escherichia coli strain HB101, heat-killed C. jejuni cells (greater than 10(10)), C. jejuni lipopolysaccharide extract, or purified lipopolysaccharide from either Vibrio cholerae 569B or Salmonella typhimurium showed no diarrheal symptoms.

Pseudomonas stutzeri bacteremia developed in six patients undergoing hemodialysis. Fever, shaking chills, nausea, and vomiting were observed. All patients recovered, although only two received specific antibiotic therapy. The infections occurred sporadically over a period of nine months. Pseudomonas stutzeri was subsequently isolated from the dialysate that circulates within the hemodialysis machine. The ultimate source was the deionized water that is combined with the liquid concentrate to form the dialysate. Pseudomonas stutzeri could be localized to the top cannister of the dialysis machine but was also isolated throughout the machine, including the bottom reservoir and the recirculating pump. The emphasis on handwashing, strict compliance with disinfection procedures, and elimination of prolonged sitting times for the filled machine after disinfection resulted in no further cases of P stutzeri infection.

It has been previously shown that antibiotics given before hospitalization significantly reduce the proportion of positive blood cultures in community-acquired pneumonia (CAP). The aim of this prospective study was to compare the utility and cost-benefits of blood cultures in patients, hospitalized for moderate CAP, who had or had not received antibiotic therapy prior to admission. During 1 year, 53 patients were included and separated into two groups: group 1 patients had not received antibiotic treatment prior to admission (n = 30), whereas group 2 patients had been treated with antibiotics (n = 23). Within the first 48 hours, a set of blood cultures was collected if the body temperature was higher than 38.5 degrees C or in the case of shaking chills. A total of 136 blood cultures was collected; 74 in group 1 and 62 in group 2. Bacteraemia was significantly more frequent in group 1 than in group 2, 5/30 patients vs. 0/23, respectively (P < 0.05). The cost of negative blood cultures was valued at 13,939.2 FF in group 1 and 13,164.8 FF in group 2, respectively 464.6 +/- 244.3 FF and 569.3 +/- 233.4 FF per patient (n.s.). Moreover, blood cultures were the method of diagnosis in only one of the five patients with bacteraemia and in no case did a positive blood-culture result influence the initial therapeutic regime. Thus, our results suggest a reduced clinical utility and cost-benefit of blood cultures in patients hospitalized for moderate CAP who have received an antibiotic treatment prior to admission.

This study tested the protective activity of antibodies to the LPS core of Haemophilus influenzae (Borrelli et al., Infect. Immun. 1995;63: 3683-92) in a hematogenous meningitis model. Meningitis was established by intraperitoneal inoculation of infant rats with H. influenzae type b (Hib). The severity of infection was determined by daily assessment of mortality, symptoms of disease and weight changes. Mortality occurred rapidly after infection with 10(5)cfu/rat and most animals died within 24 h. At a lower infection dose (10(4)cfu/rat) the rats survived, but developed symptoms of disease such as tremor, hypothermia, lethargy and anorexia within 12-72 h post challenge. Surviving animals showed decreased weight gain. Bacteremia was detected by daily blood-cultures in 10/10 rats and cleared 6 days after inoculation. The monoclonal anti-LPS antibody MAHI 3 was used in passive protection studies. MAHI 3 increased the survival in the high inoculum group (10(5)cfu/rat) from 10-17% in control animals to 60-90%. At the lower inoculum concentration (10(4)cfu/rat) MAHI 3 treatment reduced the symptoms and blood counts. Intraperitoneal injection of MAHI 3 was more effective than intranasal injection as shown by the effect on bacteremia. We conclude that anti-LPS antibodies can protect against mortality caused by hematogenous Hib infections in infant rats.

Septic shock may be defined as hypotension caused by bacteremia and accompanied by decreased peripheral blood flow, evidenced by oliguria. Clinically, a shaking chill is the warning signal. The immediate cause of hypotension is pooling of blood in the periphery, leading to decreased venous return: later, peripheral resistance falls and cardiac failure may occur. Irreversible shock is comparable to massive reactive hyperemia. Reticuloendothelial failure, histamine release, and toxic hypersensitivity may be factors in the pathogenesis of septic shock. Adrenal failure does not usually occur, but large doses of corticosteroid are employed therapeutically to counteract the effect of histamine release or hypersensitivity to endotoxin. The keys to successful therapy are time, antibiotics, vasopressors, cortisone and correction of acidosis.

Streptococcus agalactiae typically induces serious infections in pregnant women and newborns. Nonpregnant adult patients can also be infected and mortality rate exceeds 40%. CAPD peritonitis is very rarely induced by S. agalactiae. Seven cases have been described previously and all had a very severe course, which included bacteremia, septic shock and death. A 27-year-old male with end-stage renal disease due to membranoprolipherative glomerulonephritis type I, who was on CAPD for 17 months, was admitted with the clinical and laboratory picture of CAPD peritonitis. Severe abdominal pain, shaking chills and fever 38.5 microC were also observed at presentation. Streptococcus agalactiae was isolated from the peritoneal fluid and blood culture was sterile. Under treatment with ceftazidime and tobramycin (i.p.) and vancomycin (i.v.) cultures became negative after 48 hours, abdominal symptoms resolved after 12 days and WBC count in the dialysate normalized after 14 days. As a possible source of infection the patient's partner was shown to be a vaginal carrier of a clone of S. agalactiae identical to that isolated in the peritoneal fluid. S. agalactiae is a rare cause of CAPD peritonitis with potentially very serious consequences. Anal or genital tract colonization is, in general, the source of contamination with S. agalactiae. The microbiological findings in the case presented here suggest that colonization of the patient or of his close environment may be important in the pathogenesis of S. agalactiae-induced CAPD peritonitis.

The aim of this study was to determine the prevalence and predictive features of bacteremia among patients evaluated in the emergency department for urinary tract infection. Of the 350 patients with symptomatic urinary tract infection included in this retrospective study, 53 (15%; 95%CI 11.6-19.4%) were bacteremic. Five variables were independently associated with bacteremia: residence at home rather than in an institution (OR 4; 95%CI 1.5-10.7), presence of an indwelling urinary catheter (OR 3.3; 95%CI 1.3-8.8), presence of band forms in the blood count (OR 3.3; 95%CI 1.5-7.2), shaking chills (OR 2.3; 95%CI 1.1-4.8), and neutrophilia (OR 1.1; 95%CI 1.04-1.15). These easily assessable parameters may assist in the diagnosis of bacteremic urinary tract infection and the selection of empiric antibiotic treatment, thus potentially improving a patient's prognosis.
