During 8 months from October 1986 to May 1987, the clinical efficacy of sulbactam/ampicillin (SBT/ABPC) was evaluated in 63 pediatric inpatients with various infections. Clinical efficacies were evaluable in 58 patients among them (consisting of 2 patients with sepsis, 3 with tonsillitis, 12 with bronchitis, 6 with bronchopneumonia, 24 with pneumonia, 1 with phlegmon, 2 with lymphadenitis, 1 with impetigo and 7 with urinary tract infection) and were excellent in 40 patients and good in 17 with an overall efficacy rate of 98.3%. Bacteriological efficacies were assessed in 25 patients and 27 strains of organisms (consisting of 3 strains of Staphylococcus aureus, 2 Streptococcus pneumoniae, 1 Streptococcus pyogenes, 2 beta-Streptococcus, 1 Gram-positive cocci, 5 Escherichia coli, 1 Enterobacter aerogenes, 7 Haemophilus influenzae, 2 Haemophilus parainfluenzae, 1 Branhamella catarrhalis, 1 Proteus mirabilis and 1 Salmonella subgenus I). Bacteriological eradication rates were 88.9% for Gram-positive organisms, 66.7% for Gram-negative organisms and 74.1% overall. No superinfection was observed in any of patients treated. Side effects and clinical laboratory parameter abnormalities observed consisted of diarrhea in 7 (11.1%) of the 63 patients, eosinophilia in 2 (3.3%) of 61 tested, thrombocytosis in 3 (5.5%) of 55, elevation of direct bilirubin in 1 (3.3%) of 30, elevation of total bilirubin in 1 (3.1%) of 32, elevation of GOT in 4 (6.8%) of 59 and elevation of GPT in 1 (1.7%) of 59 patients tested. As an effect on the hemostatic mechanism of this drug, PIVKA II was detected in 1 patient (4.2%) of 24 tested, but findings of other coagulation tests were normal and none of patients showed bleeding tendency or inhibition of platelet aggregation. From the above results, it appears that SBT/ABPC is an efficacious and safe drug in the treatment of bacterial infections of pediatric patients.

Cefpodoxime proxetil (CPDX-PR, CS-807) is a new oral cephem derivative drug in which carboxylic acid was esterified to the 4-position of CPDX (oxime type cephem antibiotic). CPDX-PR is hydrolyzed mainly with esterase in intestinal wall and CPDX exists as an active form in body fluid. While there are numerous study reports using CPDX-PR in tablet forms in Japan, the dry syrup formula for pediatric use was newly developed. The dry syrup of CPDX-PR was orally administered 20 minutes after meal to the 6 boys of ages from 8 years and 1 month to 10 years and 10 months, with doses of 3 and 6 mg/kg, respectively, for 3 cases each. Serum concentrations and urinary concentrations and recovery rate of the drug were investigated. In addition to the above, the clinical and bacteriological studies were performed in a total of 105 cases consisting of children with ages ranging from 2 months to 11 years and 8 months, upon administering an average dose of 3.4 mg/kg, 3 to 4 times per day (96 cases of 3 times and 9 cases of 4 times). The 105 cases included 13 cases of pharyngitis, 21 cases of tonsillitis, 4 cases of acute bronchitis, 6 cases of pneumonia, 1 case of pleurisy, 13 cases of scarlet fever, 41 cases of urinary tract infection, 3 cases of posthitis and 3 cases of bacillary dysentery. Drug sensitivity test was performed for the following strains: (i) Strains retained by our department; 52 strains of Streptococcus pyogenes, 18 strains of Streptococcus agalactiae, and 11 strains of Bordetella pertussis, and (ii) strains isolated from cases to which CPDX-PR was administered; 2 strains of Staphylococcus aureus, 8 strains of S. pyogenes, 2 strains of Haemophilus influenzae, 10 strains of Escherichia coli, and 1 strain of Proteus mirabilis. Drug sensitivities of the strains retained by our department were tested with the inoculum sizes of 10(8) and 10(6) cfu/ml for R-3746 (Na-salt of CPDX), cefaclor (CCL), cephalexin (CEX), amoxicillin (AMPC), and methicillin (DMPPC), and those against strains separated from the cases to which CPDX-PR was administered were tested with the same inoculum sizes for R-3746, CCL, CEX, cefadroxil, ampicillin (ABPC), DMPPC and cloxacillin (MCIPC). Adverse reactions and abnormal clinical laboratory test results were also examined.(ABSTRACT TRUNCATED AT 400 WORDS)

We compared intravenously administered ciprofloxacin with ceftazidime in a randomized, double-blind study. Patients received ciprofloxacin 200 mg intravenously every 12 hours or ceftazidime 2 g intravenously every eight hours, with placebo infusions to maintain blinding. Therapy with metronidazole was added for suspected or documented intra-abdominal infection. Thirty-two of the 57 ciprofloxacin-treated patients were evaluable for determination of efficacy and had 41 bacterial isolates from 34 sites. Thirty-six of the 56 ceftazidime patients were evaluable for determination of efficacy and had 41 bacterial isolates from 38 sites. Seven of 35 bacteremic patients had no identifiable primary focus. The most commonly isolated pathogens were Escherichia coli, Streptococcus pneumoniae, Staphylococcus aureus, and Klebsiella pneumoniae. Cure rates and bacteriologic eradication rates were comparable. Nine patients did not improve. Patients with treatment failures in the ciprofloxacin group included a quadriplegic patient with relapse of urinary tract infection with bacteremia (K. pneumoniae). Another patient with bacteremia (Pseudomonas aeruginosa), pneumonia (Proteus vulgaris), and urinary tract infection (P. vulgaris, Providencia sp.) died on the first treatment day. The third patient (S. aureus and Streptococcus pneumoniae pneumonia) had a new aspiration pneumonia develop on the third day; the pneumococcus also persisted. Undrained S. pneumoniae empyema caused the fourth ciprofloxacin treatment failure, and the fifth patient had a relapse of S. aureus pneumonia with bacteremia. One ceftazidime-treated patient died of pneumococcal pneumonia on the first day. Another had persistent Staphylococcus epidermidis and Listeria bacteremia despite 48 hours of treatment. Two other patients had pneumonia (S. aureus and P. aeruginosa, respectively) and completed full courses of ceftazidime therapy without improvement. Five patients had pneumococcal bacteremia; four patients were cured: one of two patients in the ciprofloxacin group and three of three patients in the ceftazidime group. Significant increases in the number of platelets (four patients with ciprofloxacin treatment, one patient with ceftazidime treatment) and declines in the number of platelets (one patient with ciprofloxacin treatment, one patient with ceftazidime treatment) were observed. Intravenously administered ciprofloxacin is comparable with ceftazidime and is a safe and effective antibiotic for the treatment of patients with serious infections, including bacteremia.

Oral ciprofloxacin has been shown to be effective in the treatment of infections due to gram-positive cocci and gram-negative rods. The efficacy and safety of intravenous ciprofloxacin was compared with that of intravenous ceftazidime in the treatment of 59 patients with well-documented serious infections in a prospective, controlled, randomized study with a third-party blinding. Thirty-three patients were treated with intravenous ciprofloxacin (200 mg every 12 hours, plus a daily extra placebo dose); 26 patients were treated with ceftazidime (1 g every eight hours). The severity of the infections, underlying diseases, and demographic features were comparable in both groups, although there were more men in the ciprofloxacin group. For ciprofloxacin/ceftazidime treatments, respectively, the evaluated infections were: pyelonephritis (16 patients/nine patients), pneumonia (three/five), soft-tissue infections (four/zero), spontaneous peritonitis (five/two), primary bacteremia (three/eight), and other (two/two). Isolated pathogens included: Escherichia coli (22/12), Klebsiella sp. (five/four), Pseudomonas aeruginosa (two/three), Haemophilus influenzae (one/one), Proteus mirabilis (two/zero), Proteus vulgaris (one/zero), Salmonella sp. (zero/two), Plesiomonas shigelloides (one/zero), and others (one/four). The clinical responses were cure or improvement in 31 ciprofloxacin cases/21 ceftazidime cases; failure, zero/four; and indeterminate, two/one. The bacteriologic responses were eradication in 28 ciprofloxacin cases/22 ceftazidime cases; persistence, one/three; and indeterminate, four/one. Mild intolerance occurred in three ciprofloxacin cases and two ceftazidime cases. A mild increase in serum hepatic enzymes was observed in two patients in each group. Superinfections occurred in five patients: enterococcal septicemia (zero/two) and urinary tract infections (one/two). The results presented suggest that intravenous ciprofloxacin is an effective and safe antimicrobial agent for the treatment of serious infections, with an efficacy comparable with that of ceftazidime, a broad-spectrum cephalosporin. An additional advantage seems to be a lower rate of superinfections.

A total of 82 patients involving 83 episodes of proven or presumed bacterial infection were treated with sulbactam/ampicillin. These included 36 cases of soft tissue infection or abscess, four cases of joint or bone infection, 20 cases of respiratory tract infection (17 cases of pneumonia, two of otitis media, and one of tonsillitis), 15 urinary tract infections, three cases of enterocolitis, one case of infective endocarditis, two cases of septicemia, and two of peritonitis. The causative pathogen was isolated in 48 cases (49 infections). These pathogens included Staphylococcus aureus 13 cases, Staphylococcus epidermidis one, Streptococcus pyogenes two, Streptococcus pneumoniae two, Viridans group streptococcus two, peptostreptococcus one, Haemophilus influenzae one, Escherichia coli 12, Enterobacter cloacae three, Proteus mirabilis one, Acinetobacter calcoaceticus one, Salmonella spp. two, Shigella sonnei one, Bacteroides fragilis one, and polymicrobial infections of various combinations in five cases. No bacterial pathogens were isolated in 34 infections, 14 cases of pneumonia and 15 soft tissue infections. Sulbactam/ampicillin was given by intravenous bolus in a dosage range of 75-450 mg/kg/day in four divided doses for variable periods of time depending on the type and severity of the infection. Of a total of 83 episodes of infections, 80 (96.4%) cases were either cured or improved. Bacteriologic eradication also occurred in 46 (93.9%) of 49 infections. Side effects were diarrhea in two patients, acute hemolytic anemia in one patient, and transient elevations in SGOT and leukopenia in one patient. Side effects disappeared upon completion of treatment. Sulbactam/ampicillin is a safe and effective antibiotic for the treatment of common pediatric infections.

Forty-four camels slaughtered at Nyala abattoir, western Sudan, were examined for infection with the larvae of Cephalopina titillator. The infection rate was found to be 100 p. 100. The parasitic burden ranged between 8-243 per animal. They were recovered throughout the year. The first stage larvae were noticed from December to May, indicating the breeding season of the fly. The larvae were found to cause visible pathological lesions on the nasopharynx. These were also demonstrated histopathologically. Bacteriological examinations revealed the presence of Pasteurella haemolytica and Klebsiella ozaenae as possible causes of pneumonia, and Corynebacterium species which could possibly cause pyogenic infections locally. Organisms from the camel environment like Bacillus and Proteus species were also isolated.

Cefteram pivoxil (CFTM-PI), the pivaloyloxymethyl ester of cefteram (CFTM) in which aminothiazol was also introduced into the 7 position of cephem nucleus, is a new oral cephem antibiotic. CFTM-PI was absorbed through the intestines and hydrolyzed to CFTM by esterases in the intestinal wall and existed in the body fluids as CFTM. A tablet form of this drug has been released in Japan and now a granular form for pediatric patients has been developed. We have determined MICs of 5 drugs (CFTM, cephalexin (CEX), cefaclor (CCL), ampicillin (ABPC), erythromycin (EM], against stock strains and MICs of 6 drugs (CFTM, CEX, CCL, ABPC, methicillin, cloxacillin) against fresh strains from patients received to CFTM-PI, with an inoculum size of 10(6) cfu/ml. A total of 149 strains included Gram-positive cocci i.e. Staphylococcus aureus (11), Streptococcus pyogenes (85), Streptococcus agalactiae (16) and Streptococcus pneumoniae (4), and Gram-negative rods i.e. Haemophilus influenzae (11), Bordetella pertussis (11), Escherichia coli (9), Proteus mirabilis (1) and Morganella morganii (1). The granular form of CFTM-PI was administered to 9 boys (age: 8 years 3 months approximately 10 years 10 months) to determine serum and urinary concentrations of the drug and its urinary recovery rates using bioassay. Doses of 1.5, 3.0 and 6.0 mg/kg were given orally 30 minutes after meal to 3 boys, respectively. Urinary concentrations and its urinary recovery rates of T-2525A, a main metabolite of CFTM, were determined using high performance liquid chromatography (HPLC). To study clinical and bacteriological effects of this drug, a mean daily dose of 3.3 mg/kg divided 3-4 times a day (3 times: 133 cases, 4 times: 9 cases) was administered for 8 days on the average to a total of 142 cases with pharyngitis (22), tonsillitis (12), acute bronchitis (3), pneumonia (11), pleurisy (1), scarlet fever (28), acute purulent otitis media (16), impetigo (13), abscess (2), purulent lymphadenitis (1) and urinary tract infection (33). Adverse reactions and abnormal effects on laboratory test values attributable to this drug were studied in patients. The results obtained are summarized as follows. 1. With regard to Gram-positive cocci, MICs of CFTM against 11 fresh strains of S. aureus ranged from 3.13 to 6.25 micrograms/ml except for 1 strain, thus CFTM was equally effective to CEX, but less active than the other drugs tested.(ABSTRACT TRUNCATED AT 400 WORDS)

In a prospective study 43 patients (19 men, 24 women) suffering from severe bacterial infections such as peritonitis (n = 16), soft tissue infection (n = 12), pneumonia (n = 7), septicemia (n = 6), catheter sepsis (n = 2), cholangitis (n = 4), osteomyelitis (n = 3), complicated urinary tract infection (n = 2) or endocarditis (n = 1) were treated t. i. d. with short-time i. v. infusions of 0.5 g imipenem/cilastatin for five to 37 days (means = 9). All the patients were cured or significantly improved following therapy with imipenem/cilastatin alone or in combination with surgical intervention. The most frequent isolates were Escherichia coli, Pseudomonas aeruginosa, Proteus mirabilis, Staphylococcus aureus, Staphylococcus epidermidis and Streptococcus faecalis. 58 (83%) of the 70 pathogens isolated initially were eliminated. The 12 microorganisms (gram-negative aerobic bacteria) which persisted were non-contributory to the course of the infection and had MICs between 0.32 and 4 mg/l. The MICs for 60 isolates were less than or equal to 1 mg/l; the MICs for nine isolates were in the range of 2 to 8 mg/l. One S. epidermidis isolate presented primary resistance to imipenem (MIC 16 mg/l). The tolerability was good. Phlebitis was observed in one case only. Based on our experience we conclude that monotherapy with imipenem/cilastatin at a dosage of 0.5 g t. i. d. is appropriate for the treatment of severe bacterial infections.

The therapeutic activities of orally administered FK482 were compared with those of reference antibiotics against systemic and local infections with a variety of bacteria in mice and rabbits. In systemic infections in mice, oral FK482 was almost as effective as oral cefaclor (CCL) and more effective than oral cephalexin (CEX) against Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae and Proteus mirabilis infections. However, FK482 afforded superior protective activity when given subcutaneously against E. coli infection in mice, and this activity was more potent than that of subcutaneously given CCL. In comparison with CCL, the reason that the in vivo activity of orally given FK482 against mouse systemic infections was weaker than had been anticipated from its potent in vitro activity was due to its poor oral absorption in mice. In local infections in rabbits, a species in which FK482 was better absorbed than in mice, FK482 was more effective than CCL, CEX or amoxicillin (AMPC). Against pneumonia induced by S. aureus or Streptococcus pyogenes, FK482 was as effective as AMPC and more effective than CCL in reducing the number of viable bacteria in the lungs of infected rabbits. In the oral treatment of experimental ascending pyelonephritis in rabbits, FK482 was superior to CCL and AMPC against methicillin-resistant S. aureus infection, as effective as AMPC and more effective than CCL against Enterococcus faecalis infection, and as effective as cefixime (CFIX) and more effective than CCL and AMPC against E. coli infection in reducing the number of viable bacteria in the kidneys and urine.

The therapeutic effectiveness of a single oral dose (60 and 200 mg/kg body weight) of fosfomycin trometamol (FT), norfloxacin, trimethoprim sulfamethoxazole (Bactrim) and pipemidic acid against experimental cystitis in the rat were compared. Infections were produced with clinical isolates of Klebsiella pneumoniae, Proteus mirabilis and Escherichia coli in a total of 135 Sprague-Dawley albino rats. Oral treatment with all four drugs consistently lowered the numbers of CFU in bladder tissue, especially E. coli and P. mirabilis. Fosfomycin trometamol appeared to be as effective as norfloxacin for treatment of E. coli cystitis even thoughs its minimal inhibitory concentration (MIC) in vitro is 100 times greater than that of the quinolonic antibiotic. Fosfomycin trometamol, pipemidic acid and Bactrim were equally effective against P. mirabilis infection, but FT was less active than norfloxacin or Bactrim for treatment of K. pneumonia cystitis. In conclusion, single dose treatment with fosfomycin trometamol was effective for treatment of experimental cystitis in the rat and might, by extrapolation, be of use in clinical practice for single dose treatment of uncomplicated urinary tract infections.
