A total of 296 episodes of bacteremia due to Enterobacter occurred in 281 patients with cancer between 1972 and 1986. The majority of these episodes were caused by Enterobacter cloacae. Seventy-four percent of the patients developed their infection while in the hospital and 55% had received therapeutic antibiotics during the 10 days preceding the onset of the infection. Enterobacter bacteremia was associated with shock in 24% of the patients and with disseminated intravascular coagulation in only 3%. The overall rate of response to therapy was 79% and increased to 85% during the last 5-year period. Only five patients remained afebrile during their infection, but four of these five died. Only 37% of the patients with shock responded to therapy compared with 93% of the patients without shock. The rate of response to therapy was 86% among patients without pulmonary infection compared with only 53% among those with pulmonary infection. The response rate to therapy with a single antibiotic was 73% and that to therapy with two antibiotics was 85%. As single therapeutic agents aminoglycosides were less effective than beta-lactam agents.

We analyze retrospectively all bacteremic episodes seen between January and December, 1987 in our institution. From a total number of blood cultures performed of 897, 145 were positive (16%), and 67 of them considered as contamination (7.5%). There were 78 episodes of bacteremia in 74 patients, 38 males and 36 females. Forty-eight episodes were community-acquired and 30 were nosocomial bacteremia episodes. Aerobic bacteria were isolated in 64 cases, anaerobic bacteria in 9 cases and polymicrobial bacteremia in 5 cases. The most commonly isolated microorganism was S. epidermidis in nosocomial cases and E. coli in community-acquired cases. Predisposing conditions registered were diabetes mellitus in 16 cases (20%), cirrhosis of the liver in 3 (4%), corticosteroid therapy in 7 (9%) and surgical procedures in 19 (24%). Shock was seen in 16 cases (20%), DIC in 8 cases (10%) and ARDS in 5 (6.5%). Appropriate antibiotic treatment was used in 60 episodes (77%). Seventeen patients (22%) died. Prognostic factors identified were: nosocomial bacteremia (p less than 0.05), corticosteroid prior therapy (p less than 0.05), underlying disease UF or RF (p less than 0.0001) and the presence of shock (p less than 0.0001). Mean hospital stay was 20.1 days in bacteremic patients vs. 7.6 days in non bacteremic patients (p less than 0.00001).

Clostridial bacteremia is rare and has a variable presentation from asymptomatic to septic shock with disseminated intravascular coagulation (DIC), red cell hemolysis, and rapid death. In order to delineate the predisposing and prognostic factors in these patients, the authors reviewed 47 cases of clostridial bacteremia presenting over a seven year period at a major metropolitan teaching hospital. Predisposing factors included locally decreased oxidation reduction potential (Eh) in 43 per cent (including atherosclerosis, diabetes, and radiation therapy), systemic immunosuppression in 53 per cent (including alcohol abuse, chemotherapy, steroids, and malignancy), and a site of epithelial barrier disruption. The sites of clostridial invasion included: gastrointestinal tract (GI) (n = 22), pulmonary (n = 7), cutaneous (n = 7), undetermined (n = 7), and female genital tract (n = 4). Seven patients were found to have malignancy. Seventy-nine per cent of the blood culture isolates were histotoxic species (Clostridia perfringens and C. septicum). The overall mortality was 47 per cent. Significant differences between survivors and deaths included DIC, new onset renal failure, severe atherosclerotic disease, and age (P less than .05). The authors conclude that clostridial bacteremia is uncommon but highly lethal and may occur when decreased tissue Eh, systemic immunosuppression, and an epithelial barrier disruption are present. Poor outcome appears to be a reflection of advanced age, underlying illness, and presence of a histotoxic species.

Human plasma contains an inhibitor of tissue factor-initiated coagulation known as the lipoprotein-associated coagulation inhibitor (LACI) or also known as the extrinsic pathway inhibitor (EPI). A competitive fluorescent immunoassay was developed to measure the plasma concentration of LACI in samples from normal individuals and patients with a variety of diseases. The LACI concentration in an adult control population varied from 60% to 160% of the mean with a mean value corresponding to 89 ng/mL or 2.25 nmol/L. Plasma LACI levels were not decreased in patients with severe chronic hepatic failure, warfarin therapy, primary pulmonary hypertension, thrombosis, or the lupus anticoagulant. Plasma LACI antigen was decreased in some, but not all patients with gram-negative bacteremia and evidence for disseminated intravascular coagulation. Plasma LACI levels were elevated in women undergoing the early stages of labor (29%), in patients receiving intravenous tissue-type plasminogen activator (45%), and in patients receiving intravenous heparin (375%). A radioligand blot of the pre- and post-heparin plasma samples shows the increase to be in a 40-Kd form of LACI. Very low levels of plasma LACI antigen were found in patients with homozygous abetalipoproteinemia and hypobetalipoproteinemia, diseases associated with low plasma levels of apolipoprotein B containing lipoproteins. Following the injection of heparin into one patient with homozygous abetalipoproteinemia, the plasma LACI antigen level increased to a level comparable with that in normal individuals after heparin treatment.

Although bacteremia caused by non-typhoidal salmonella is frequently observed in immunocompromised hosts, it is rare to find this condition in healthy subjects. In this report, we present a case of bacteremia due to Salmonella enteritidis detected in a healthy man. A 59-year-old man was admitted to our hospital with a fifty-day history of fever on May 18, 1985. On admission, he showed no symptoms except high body temperature (38.8 degrees C). In the laboratory data, C-reactive protein was 3+, white- cell count was 9600, and erythrocyte sedimentation rate was 12 mm/h. Culture in blood and stool yielded Salmonella enteritidis. However, no abnormal findings were found in UGIS, barium enema, OC + DIC, abdominal CT and echography. As soon as Ampicillin was administered, the fever was gone and the blood culture yielded nothing. After six months, the stool culture was negative for pathological intestinal bacterial flora and he was in good physical condition. Generally, bacteremia develops mainly in the immunocompromised hosts, such as patients with neoplastic disease, AIDS, leukemia or collagen disease. The literature provides so far twenty three adult cases of bacteremia due to non-typhoidal salmonella in Japan. Only two of them had no systemic disease as well as our case. Although it is unknown why bacteremia developed in this healthy man, we reported that bacteremia developed rarely in subjects with healthy condition.

We prospectively evaluated 61 episodes of bacteremia in 54 patients with hepatic cirrhosis, representing 9% of the overall number of bacteremic episodes in adult patients seen in our center during the study period. Spontaneous bacteremia represented 46% of all episodes (virtually always in patients with ascites), followed by the urinary origin (30%). Gram negative organisms were isolated in 71% of episodes. 43% of these were hospital-acquired 25% of patients had spontaneous peritonitis. Among other complications of bacteremia there were shock (28%), renal failure (24%), and disseminated intravascular coagulation (6%). The mortality rate due to sepsis was 28%, that due to complications of cirrhosis by itself was 20%, and that of nonrelated diseases was 8%. Shock and renal failure secondary to bacteremia were independent predictors of a poor prognosis.

Candidemias were reviewed in 22 elderly patients hospitalized in Yokufukai Geriatric Hospital. Their ages ranged from 62 to 101 years, with a mean age of 81 years. Sixteen patients had either old cerebrovascular disease or senile dementia. In seven patients, synchronous or metachronous bacteremia in the blood culture was associated with the candidemia. Eighty-six percent of total candidemias were related to intravenous hyperalimentation (IVH). The mean duration from the start of IVH to candidemia was 46 days. Eleven patients (50%) developed candidemia within one month after the beginning of IVH. Fourteen patients had the IVH catheters changed one or more times before the time of positive candida in the blood culture. The mean duration from the start of IVH to candidemia was 59 days. Eight patients, on the other hand, had the catheters unchanged and the mean duration was 23 days. Ninety-six percent were receiving broad-spectrum antibiotic therapy at the time of the positive candida in blood culture. Eight patients developed DIC. The overall mortality was 91% (twenty patients) and thirteen (65%) of them died within one month after the onset of candidemia. There was no difference in mortality when all candidemic patients received no anti-mycotic therapy were compared with the patients given any amount of miconazole or 5-FC. The causes of death for candidemic patients included fungemic shock (6 patients), hemorrhagic shock (4 patients), and shock associated with DIC (3 patients). From the results of this study, candidemia in the elderly was produced by various underlying diseases such as central nervous system diseases or pneumonia.(ABSTRACT TRUNCATED AT 250 WORDS)

Although polymicrobial bacteremia has been described in several previous series, there has been no recent study of patients using rigorous statistical analysis. Our objective was to characterize a present-day patient population with polymicrobial bacteremia and to define factors prognostic of survival. Polymicrobial bacteremia accounted for 6% of all positive blood cultures at a university hospital and a Veterans Administration hospital over a 2 1/2 year period in the late 1980s. The majority of these patients were elderly with significant underlying diseases, notably malignancies, and 56% of all episodes were nosocomially acquired. Enterobacteriaceae have remained the most common organisms, though the frequency of gram-positive cocci isolated has increased compared to older studies. Gastrointestinal, genitourinary, and skin and soft-tissue sources were the most common, although the incidence of infections due to central venous catheters appeared to be increasing. The source of 25% of bacteremia was not identified despite newer diagnostic techniques. By univariate analysis, mortality, which was 36% overall, correlated with thrombocytopenia, respiratory failure, disseminated intravascular coagulation, encephalopathy, severity of underlying disease, hemolysis, adult respiratory distress syndrome, use of steroids, renal insufficiency, institution, presence of central lines, and nosocomial acquisition. Using stepwise logistic regression analysis, mortality was predicted by respiratory failure, severity of underlying disease, and hemolysis. We conclude that polymicrobial bacteremia remains an important entity in the present-day hospitalized population, with an increasing frequency of gram-positive organisms and catheter sources, and a large proportion of undiagnosed etiologies.

Fatal pneumococcal bacteremia, disseminated intravascular coagulation and Waterhouse Friderichsen syndrome in a vaccinated, splenectomized adult were caused by serotype 22F (Danish classification), which was not included in the vaccine. Revaccination with a 23-valent pneumococcal vaccine and antibiotic prophylaxis are advocated for patients who have undergone splenectomy.

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.
