Because of the persistently high mortality from sepsis in cancer patients, a retrospective study was designed to identify the causative organisms and to determine the factors affecting the outcome of sepsis. A total of 84 episodes of septicemia in 61 children with cancer were studied. The more frequently isolated organisms were: Staphylococcus aureus (21.4%); Escherichia coli (18%); Klebsiella (7.1%); Pseudomonas (6%); and Bacteroides fragilis (6%). Other isolates included Proteus, Serratia, Acinetobacter, hemolytic Streptococcus, and Bacillus cereus. In 10.7% of septic episodes, mixed bacterial infections were documented. Twenty-four (28.6%) resulted in death; in 13 (54%) death occurred within 24 hours after admission. The fatality rate was high in cases associated with absolute polymorphonuclear leukocyte counts of less than 100/cu mm, in neoplastic relapse, and when infection with gram-negative, anaerobic and mixed bacterial flora occurred.

The study on sensitivity of clinical strains of the causative agents of purulent infections to carbenicillin showed that 34.6% of the staphylococcal strains, 48.1% of the E. coli strains and 40.3% of the Proteus strains were sensitive to the antibiotic. The strains of Ps. aeruginosa were characterized by moderate sensitivity to carbenicillin. The MTC for most of the isolates ranged within 25-128 microgram/ml. High therapeutic efficacy of carbenicillin in treatment of cases with purulent inflammatory processes of various localization was shown. Positive results were obtained in 82.5% of the adults and 76.2% of the premature infants treated with carbenicillin. A satisfactory therapeutic effect was observed in the cases with sepsis, diffuse purulent peritonitis and abscessing pneumonia treated with carbenicillin in combination with gentamicin.

Three groups of extensive burn patients of the surgical intensive care unit (ICU) have been compared: Group I: twenty patients, who were treated locally without silver sulfadiazinate (1968-1970); Group II: the twenty first patients topically treated with silver sulfadiazinate (1970-1972); Group III: twenty similarly treated patients, with silver sulfadiazinate, six years later (1976-1977). The groups are statistically comparable. All bacteriological samples were computerized; the chi-square method was used for statistical analysis of the data. The main conclusions are: (A) Silver sulfadiazinate treatment reduced Pseudomonas aeruginosa and Proteus sepsis. No change in Coliform bacilli sepsis was observed. After six years, a rise in Klebsiella sepsis and Candida sepsis was noted. (B) A quantitative estimate of infections in each group was made by measuring the percentage of positive samples, taking into account the five above-mentioned strains. In the beginning, silver sulfadiazinate reduced quantitative sepsis, but this benefit decreased after six years; the same evolution was demonstrated for positive blood bacteriology; severe septicaemia showed a parallel pattern.

Twenty-five patients were treated with ticarcillin disodium, 18 of whom had anaerobic infections that included pleuropulmonary infections (seven), mandibular osteomyelitis (four), perirectal abscess (two), sepsis, primary site unknown (one), liver abscess (one), pelvic abscess (one), decubitus ulcer (one), and synergistic gangrene (one). Seven had no anaerobic infections. Three had anaerobic septicemia. Culture results included anaerobes: peptococci (ten), peptostreptococci (ten), Bacteroides fragilis (six), Bacteroides not fragilis (ten), eubacteria (three), fusobacteria (two), Clostridium (one), Veillonella (one), and acidaminococcus (one); aerobes: Proteus (three), Klebsiella (two), Escherichia coli (two), and streptococci (two). Six patients with mixed aerobic infections initially received gentamicin sulfate in addition. The serum levels were 110 +/- 20 microgram/ml one hour after intravenous infusion of 5 g of ticarcillin disodium. All anaerobic isolates were susceptible at less than or equal to 100 microgram/ml and 85% by less than or equal to 25 microgram/ml of ticarcillin. Sixteen patients responded well to ticarcillin and two failed to respond. Our study suggests that ticarcillin is useful in the treatment of anaerobic infections.

Of 611 prospectively studied patients in a surgical intensive care unit, 177 developed hospital infections (29%): urinary tract infections (37.2%), pneumonia (22.5%), sepsis (19.7%), wound infections (9.6%), etc. The commonest pathogens were Pseud. aeruginosa, E. coli, Staph. aureus, enterococci, Klebsiella pneumoniae and Proteus mirabilis. In preventing and combating hospital infections in intensive care units, priority should be given not to antibiotics but to hygiene in the hospital. Systemic antibiotic prophylaxis prevents neither hospital-contracted pneumonia, sepsis nor urinary tract infections. There is an urgent need for controlled studies on the necessity and selection of locally active antibacterial and antimycotic substances to prevent germ ascension in vein and bladder catheters.

Antibacterial activity of gentamycin sulfate was studied in vitro and in treatment of albino mice with experimental infections. Gentamycin was superior to kanamycin with respect to its antibacterial effect against clinical strains of Staphylococcus, Coli bacteria, Proteus and Ps. aeruginosa. High efficiency of gentamycin was found with respect to acute and chronic staphylococcal infection, acute Proteus and Coli sepsis. The antibiotic was characterized by low LD50, high chemotherapeutic index, rapid decrease in isolation of the causative agent from the animal organs. The activity of gentamycin against infections caused by Ps. aeruginosa was the main advantage of gentamycin in comparison to kanamycin.

Bacteremia was documented in 19 (76%) of 24 patients with sepsis caused solely by decubitus ulcers, persisted in all but two, and was polymicrobial in 10 (42%). Obligate anaerobes were isolated from 12 patients (63%) and included Bacteroides fragilis in 11 (58%). Aerobes, primarily Proteus (21%) and Staphylococcus (16%), were isolated in nine patients (47%). Therapy was judged appropriate when the microbial isolates were susceptible in vitro to the antibiotic used. Nineteen patients received clindamycin plus gentamicin, which was considered appropriate for all but one patient. Four patients received cephalothin plus kanamycin, which was inappropriate for three patients. One patient received appropriate treatment with methicillin, gentamicin, and chloramphenicol. Patients who received appropriate antibiotics and had surgical intervention had the lowest mortality rate (14%); in those treated with appropriate antibiotics but without surgical intervention, the incidence of death was 67% (P less than 0.05). Patients who received inappropriate antibiotics, whether or not there was surgical intervention, had a 75% mortality rate (P less than 0.05). Surgical debridement and antibiotic therapy effective against aerobic as well as anaerobic bacteria are important factors in the treatment of sepsis caused by decubitus ulcers.

Clindamycin and gentamicin were used in combination to treat 107 patients empirically for suspected aerobic-anaerobic sepsis. All patients were seriously ill and required initiation of treatment before results of cultures could be obtained. Infections included intraabdominal sepsis, hospital-acquired aspiration pneumonia, and soft tissue infections. Exudate cultured from 65 patients showed that the prediction of a mixed aerobic-anaerobic flora was correct in 46 patients (71%). Isolates from exudate included Escherichia coli, Bacteroides fragilis, clostridia, peptostreptococci, Proteus species, Klebsiella species, and Staphylococcus aureus. In 29 patients with bacteremia, the most frequent blood culture isolate was B. fragilis. Analysis of response to treatment showed that 92 patients were cured, five could not be evaluated adequately, and 10 failed to respond to therapy. Therapeutic failure primarily resulted from overwhelming sepsis, despite susceptibility of the pathogens to prescribed antibiotics.

The safety and efficacy of tobramycin and cephalothin in treatment of suspected sepsis were studied in neutropenic children with various malignancies. Twenty episodes of suspected sepsis in 19 febrile children with cancer were treated with parenteral tobramycin and cephalothin; the duration of therapy ranged from one to 80 days. In 14 of the 20 episodes of suspected sepsis, a favorable clinical response was achieved within five days after initiation of antibiotic therapy. These episodes included a urinary tract infection with Proteus mirabilis and sepsis due to Escherichia coli. In four of the additional six episodes, clinical deterioration was though to be caused by the underlying malignancies. Two episodes included a case of E. coli spesis that ended fatally and a nosocomial infection with Eikenella corrodens. Results of this study suggest that combination therapy with tobramycin and cephalothin is safe and efficacious in treatment of suspected sepsis in febrile children with malignancies and neutropenia.

The minimal inhibitory concentrations of gentamicin and minocycline alone and in combination were determined by a broth microdilution method for 100 aerobic, facultative, and anaerobic isolates representative of pathogens recovered from patients with intra-abdominal sepsis. Gentamicin inhibited all strains of Klebsiella, Enterobacter, and Pseudomonas aeruginosa in concentrations of 0.4 to 3.1 mug/ml and all strains of Escherichia coli and Proteus mirabilis in concentrations of 0.8 to 12.5 mug/ml. Whereas minocycline did not consistently inhibit these organisms in concentrations of 1.6 mug or less/ml, it did act synergistically with gentamicin against 43% of the Enterobacteriaceae tested in clinically achievable concentrations; significant synergy was most common with E. coli (60%). Minocycline inhibited 62% of Bacteroides fragilis, 71% of Clostridium, 40% of anaerobic cocci, and 40% of enterococci tested in concentrations of 1.6 mug or less/ml. Whereas gentamicin rarely inhibited these organisms in concentrations of 6.2 mug or less/ml, it did act synergistically with minocycline against 20% of B. fragilis, 67% of Clostridium, 22% of anaerobic cocci, and 22% of enterococci (which had minimal inhibitory concentrations of minocycline within the range tested) at clinically achievable concentrations. Although only four (13%) of the 30 isolates resistant to both gentamicin and minocycline alone were inhibited by clinically achievable concentrations of the combination, the observed synergy, particularly against strains of E. coli, was considered to be of potential clinical usefulness. Antagonism between gentamicin and minocycline was not observed at the concentrations tested.
