Adult patients with bacterial infections of the lower respiratory tract were given either cefoperazone or cefamandole in a multicenter clinical study of the clinical and bacteriologic efficacy of cefoperazone. Clinical diagnoses included pneumonia, bronchitis, lung abscess, and bronchiectasis. Efficacy was evaluated in 119 patients given cefoperazone and 73 patients given cefamandole. Major pathogens isolated included Streptococcus pneumoniae, Haemophilus influenzae, Staphylococcus aureus, Klebsiella pneumoniae, and Pseudomonas aeruginosa. Satisfactory clinical responses were noted for 96% of the patients in both treatment groups, including 14 of 17 patients given cefoperazone who were primarily infected with P. aeruginosa. Satisfactory bacteriologic responses were noted for 88% of the group given cefoperazone and 89% of the group given cefamandole. Adverse reactions related to the antibiotic occurred infrequently in each treatment group. The results of this study indicate that cefoperazone is a safe and effective antibiotic for the treatment of lower respiratory tract infections due to S. pneumoniae, H. influenzae, S. aureus, and many gram-negative bacilli, including susceptible strains of P. aeruginosa, in adult patients.

Fundamental and clinical studies of ceftizoxime, a new cephalosporin antibiotic, in children led to the following results. 1. Ceftizoxime compared favorably with cefazolin (CEZ) and cefmetazole (CMZ) for in vitro activity against clinically isolated strains of Staphylococcus aureus (31 strains), Escherichia coli (29), Klebsiella pneumoniae (30) and Pseudomonas aeruginosa (16). While somewhat less active against S. aureus than CEZ and CMZ, ceftizoxime was far more active than these 2 cephalosporin antibiotics against the test strains of E. coli and K. pneumoniae, which included strains resistant to the 2 drugs. Ceftizoxime was not particularly active against Ps. aeruginosa, but this seeming disadvantage was offset by the absolute ineffectiveness of the 2 reference drugs on this obstinate organism. 2. The time course of mean serum ceftizoxime levels in 3 pediatric patients of 5--10 years old given a single intravenous dose of 20 mg/kg was as follows: 45.4 micrograms/ml at 15 minutes, 40.4 micrograms/ml at 30 minutes, 22.1 micrograms/ml at 1 hour, 10.4 micrograms/ml at 2 hours, 2.9 micrograms/ml at 4 hours and 0.9 microgram/ml at 6 hours. The mean serum half life was 1.12 hours. The mean urinary levels of ceftizoxime at serial 2-hour collection intervals were as follows: 2,477 micrograms/ml for 1--2 hours, 1,235 micrograms/ml for 2--4 hours and 462 micrograms/ml for 4--6 hours. The mean urinary recovery up to 6 hours was 61.0%. 3. The clinical response of 28 children with infection to ceftizoxime treatment was 'excellent' in 22 children, 'good' in 4, and 'poor' in 2. These children comprised 11 with acute pneumonia, 3 with acute bronchitis, 4 with acute pyelonephritis, 2 each with acute purulent arthritis and acute enterocolitis, and 1 each with acute purulent tonsillitis, acute purulent lymphadenitis, furunculosis, subcutaneous abscess, subdural abscess and sepsis. The overall rate of effectiveness was 92.9%. Successfully eradicated strains in the bacteriological sense consisted of 4 strains each of H. influenzae and E. coli, 1 strain each of P. morganii, S. pneumoniae and S. pyogenes, 1 of the 2 strains of S. enteritidis, and 1 of the 3 strains of S. aureus. The overall rate of bacteriological effectiveness was 81.3%. No clinical side effects were observed. Changes in laboratory test findings included slightly and transiently elevated GOT and GPT in 1 child and GOT alone in another child.

Ceftizoxime, a new cephalosporin preparation, was evaluated for its antibacterial activity, absorption, excretion and clinical effectiveness, and the following results were obtained. The minimum inhibitory concentrations (MICs) of ceftizoxime against 211 clinical isolates were determined in comparison with those of cefazolin, cefmetazole, cefotiam and 6059 S. Against S. pyogenes (50 strains), ceftizoxime was 1 tube inferior to cefazolin inoculum size of 10(8) cells/ml, but was 2--3 tubes superior to cefmetazole and 6059-S. Against E. coli (50 strains), ceftizoxime and 6059-S were significantly more active than the other drugs. The susceptibility pattern of Klebsiella sp. (50 strains) to ceftizoxime was similar to that to cefotiam and 6059-S. Against Proteus sp. (50 strains), cefotiam and 6059-S were more active than the other drugs. Ceftizoxime was intermediate in activity, and cefazolin was the least active. Against H. influenzae (11 strains), ceftizoxime was the most active, with concentrations of 0.1 mcg/ml required to inhibit 100% of strains with an inoculum size of 10(8) cells/ml and 10(6) cells/ml. A dose of ceftizoxime 10 mg/kg or 20 mg/kg was administered to 15 patients aged from 5 years to 12 years, and serum levels and urinary excretion of the drug were measured. Intravenous bolus injection of the drug in dose of 10 mg/kg and 20 mg/kg yielded mean serum levels of 26.6 mcg/ml and 55.7 mcg/ml at 30 minutes, respectively. The serum levels of the drug, thereafter, declined gradually but still remained 1.3 mcg/ml and 2.7 mcg/ml at 6 hours. The serum half-lives (T 1/2) were estimated to be 1.17 hours in dose of 10 mg/kg and 1.31 hours in dose of 20 mg/kg. When a dose of 20 mg/kg was infused over a period of 30 minutes, the serum levels attained the peak of 72.4 mcg/ml to 82.4 mcg/ml (mean 79.4 mcg/ml) at the end of infusion. The levels, thereafter, tapered to mean levels of 45.3 mcg/ml at 30 minutes, 24.7 mcg/ml at 1 1/2 hours, and 3.6 mcg/ml at 5 1/2 hours, with a T 1/2 of 1.22 hours. Meanwhile, when the same dose was infused over 1 hour, the serum levels attained the peak of 59.4 mcg/ml to 68.5 mcg/ml (mean 64.2 mcg/ml). The mean serum levels after the end of infusion were 41.3 mcg/ml at 30 minutes, 21.6 mcg/ml at 1 hour and 1.9 mcg/ml at 5 hours, with a T 1/2 of 0.97 hours. Urinary recovery of the drug was 69.2% to 79.9% after intravenous injection and 62.3% to 79.9% after drip infusion, most of the given drug was excreted in the first 2 hours after administration. In our clinical study, 27 children with moderate or severe infections (12 cases of bronchopneumonia or bronchitis, 5 of pyelonephritis, 3 of purulent meningitis, etc.) were treated with ceftizoxime at the daily dose of 30--309 mg/kg for 3--23 days. Clinical response was excellent in 10, good in 9, fair in 5 and poor in 3. The drug was proved to be very effective against infections due to H. influenzae K. pneumoniae, E. coli and S. aureus. No serious side effects were observed in any case.

Cefmenoxime (CMX) was evaluated in 25 children with a suspicion of bacterial infection. Of the 20 confirmed bacterial infections, 19 were cured by CMX therapy (effective rate, 95%). The diagnoses included acute pharyngotonsillitis (4), acute bronchitis (1), pneumonia (7), streptococcal dacryocystitis (1), infections accompanied with acute leukemia (4), and acute urinary tract infections (3). The etiologic pathogens were beta-hemolytic Streptococcus group A (1), and F (1), Staphylococcus aureus (4), Haemophilus influenzae (4), Escherichia coli (4), Klebsiella pneumoniae (2), etc. CMX was very effective for 2 children with respiratory infections due to ampicillin resistant H. influenzae type b. The half life of serum concentration of CMX was 0.76 +/- 0.17 hour after an intravenous bolus injection. A cerebrospinal fluid level of CMX was 5.2 mcg/ml 1 hour after intravenous injection of 1 g (23.8 mg/kg) in a child with inflamed meninges. However this level was not as high as those of cefotaxime, latamoxef, or ceftizoxime measured in the same case. No severe adverse reaction was encountered with CMX therapy. The data suggest that CMX is a safe and effective parenteral antibiotic when used in children with susceptible bacterial infections.

To evaluate the antibacterial potency of cefotiam (CTM) clinical and laboratory studies were carried out and the results were as follows. Clinical evaluation and adverse reaction CTM was given to total of 23 patients, 10 with bronchopneumonia, 10 with bronchitis and one each with cystitis, enteritis and suspected sepsis. Overall efficacy rate was 78.3% (18/23) (excellent 9, good 9, fair 3, poor 2). Only 1 case showed a side effect of slightly elevated GOT and GPT. Antibacterial activities MIC of CTM against isolates from sputum was investigated on those patients mentioned above and was compared with MIC of CEZ and CMZ. CTM showed superior antibacterial activity against almost all strains. Especially on Haemophilus and Klebsiella antibacterial activity of CTM was impressive. Organisms in sputum Four out of 8 causative bacteria disappeared and 1 out of 8 decreased after administration of CTM. Thus CTM is considered to be the useful drug for the treatment of respiratory infection.

Ten inpatients at the Second Department of Internal Medicine, Mie University Hospital, developed infections in the course of treatment for hematopoietic disorders and were administered cefoxitin (CFX). Patients suffered from the following infections: pharyngitis, 2; bronchitis, 2; pneumonia, 2; sepsis, 2; bacteremia, 1; suspected cases of bacteremia, 2; and fever of unknown origin, 1. The number of infections totaled 12 as 1 patient with pharyngitis also developed sepsis and 1 patient with pneumonia developed bacteremia. Duration for the administration of CFX ranged between 5 and 18 days with a total dosage of between 30 and 108 g. Of the 10 patients treated with CFX, 9 were treated concomitantly with micronomicin (MCR), doxycycline (DOXY), or sulbenicillin (SBPC), some were treated concomitantly with only 1 of the drugs and some were treated concomitantly with 2 of the drugs. The following clinical results were obtained: Following treatment, 4 patients were considered "excellent", 5, "good", and 3, "poor". Clinical efficacy rate was 75%. Four strains of Gram-positive cocci (1 strain of S. aureus, 2 strains of S. epidermidis and 1 strain of Streptococcus sp.) and 3 strains of Gram-negative rods (2 strains of P. aeruginosa and 1 strain of E. cloacae) were found in the clinical specimens of the 10 patients. These results differed somewhat from reported data that Gram-negative rods such as E. coli, Klebsiella sp., Pseudomonas sp., Serratia sp., are dominant. No serious side effects requiring cessation of treatment were observed. Elevations in the levels of S-GOT, S-GPT, serum alkaline phosphatase, blood urea nitrogen, etc. were observed.(ABSTRACT TRUNCATED AT 250 WORDS)

Studies on antimicrobial activity, absorption and excretion and clinical use of cefoxitin in pediatric field were performed. 1. MIC of cefoxitin was compared with that of cefazolin and/or ampicillin for clinical isolates of Staphylococcus aureus (36 strains), Escherichia coli (35 strains), Klebsiella pneumoniae (34 strains) and Haemophilus influenzae (80 strains). MIC of cefoxitin against S. aureus was approximately 1-2 tubes higher than that of cefazolin. Many strains of E. coli and K. pneumoniae that showed high MIC to cefazolin were sensitive to cefoxitin. It is presumed that the results are due to the strong resistance of cefoxitin to beta-lactamase degradation. MIC of cefoxitin against H. influenzae was approximately 1-2 tubes lower than that of cefazolin, but approximately 4 tubes higher than that of ampicillin. 2. Serum level and urinary recovery rate of cefoxitin after one shot i.v. injection of 25 mg/kg were examined. The serum mean levels were 33.8 microgram/ml at 1/2 hour, 7.0 microgram/ml at 1 hour and 2.9 microgram/ml at 2 hours after the injection, respectively, and the drug was not detected in serum at 4 and 6 hours after the injection. The mean half-life of serum level was 27.1 minutes. The mean urinary recovery rate within 6 hours after injection was 96.0% and most of the drug were excreted into urine within 2 hours after the injection. 3. In order to evaluate clinical response, bacteriological response and side effects, cefoxitin was applied to 19 cases, i.e., 12 cases of either acute lobar pneumonia or acute bronchopneumonia, 2 cases of acute pyelitis, 1 case each of acute bronchitis, acute purulent tonsillitis, acute purulent arthritis, acute orbital phlegmon and acute buccal abscess. As for clinical response, the overall efficacy rate (the percentage of cases showed excellent and good efficacy) was 88.9%. As for bacteriological response, among the 13 strains which were determined or supposed to be causative organisms, i.e., 6 strains of Streptococcus pneumoniae, 2 strains of H. influenzae and 1 strain each of streptococcus pyogenes, alpha-Streptococcus, Enterococcus, E. coli and Neisseria sp., all strains were disappeared except for Enterococcus which was reduced by the treatment with cefoxitin. No side effect was observed in any case. Abnormalities of laboratory findings were observed in 3 cases, i.e., 1 case each of reduction of RBC and Hb, elevation of GOT and GPT and elevation of GPT, but all of them returned to normal following completion of the dosage term.

The pattern of distribution of bacteria, Mycoplasma pneumoniae and virus isolated from the same specimen recovered from the throat swab or the sputum of 479 patients with respiratory infections who were seen in six private clinics in Sendai City of Japan during the period from October to November in 1992 (period I) and from January to February in 1993 (period II) was documented. Of the 479 patients, 234 had acute pharyngitis, 145 had acute bronchitis, 96 had influenza, 21 had acute tonsillitis, 5 had acute pneumonia and 9 had other respiratory infections. One hundred (42.4%) strains of potential pathogen and one strain of M. pneumoniae were recovered from 236 cases in period I, and 66 (27.2%) strains of potential pathogen, one strain of M. pneumonae and 73 strains of Influenza virus (30.0%: 43 of type A Hong-Kong and 30 of type B) from 243 cases in period II. Of the 166 strains, major isolates were Staphylococcus aureus (56 strains), Streptococcus pneumoniae (12 strains), Streptococcus pyogenes (15 strains), Haemophilus influenzae (17 strains), Esherichia coli (4 strains), Klebsiella spp. (35 strains), Pseudomonas aeruginosa (4 strains) and Acinetobacter spp. (23 strains). Only one strain of S. aureus was resistant to methicillin (MIC: 50 micrograms/ml). None of S. pneumoniae was resistant to 1 microgram/ml of ampicillin. Ciprofloxacin was administered to 113 cases and roxythromycin to 220 cases by doctors in charge.(ABSTRACT TRUNCATED AT 250 WORDS)

The aim of this study was to determine the clinical and bacteriological efficacy and safety of piperacillin-tazobactam (PT) (4g/500 mg IV tid) in the treatment of 107 adult patients with lower respiratory tract infections (LRTI) requiring hospitalization. Patients included were 66 men and 41 women with a mean age of 55.2 years (range 18-89), enrolled from Mexican (6) and Argentinean (5) hospitals. Ninety-nine clinically evaluable patients (92.5%), 87 with pneumonia and 12 with bronchitis, were treated for a mean period of 9.3 and 7.3 days, respectively. Response to treatment was favorable in 94.3% cases with pneumonia and 100% of cases with bronchitis; 86 cases (80.3%) were bacteriologically evaluable, 77 with pneumonia (eradication 74, persistence 1, superinfection 2), and 9 with bronchitis (eradication in all). Streptococcus pneumoniae was recovered in 24, Klebsiella pneumoniae in 21, Staphylococcus aureus in 8, Haemophilus influenzae in 7, Pseudomonas aeruginosa in 5, Enterobacter spp. in 6, Escherichia coli in 6 and other organisms in 12. Toxicity or intolerance were not observed. Our data suggest that PT is a reliable therapy for severe LRTI.

The effects of S-1108, an orally active cephem antibiotic newly synthesized by Shionogi Res. Lab., on pediatric bacterial infections was studied. S-1108 was administered orally at a daily dose between 9.3 and 12.4 mg/kg in three divided doses (after each meal) for 5 to 11 days to patients with pharyngitis (2), tonsillitis (1), bronchitis (3), pneumonia (1), lymphadenitis (1), enteritis (1) and cystitis (1). The clinical efficacy rate was 100% with excellent responses in 3, good in 6 and undetermined in 1. Bacteriological effects observed indicated that one strain each of Streptococcus pneumoniae, Streptococcus pyogenes, Klebsiella pneumoniae and two strains of Haemophilus influenzae were eradicated by the treatment. No clinical side effects and laboratory test abnormalities were observed at all in this study. These results suggested that S-1108 would be a useful antibiotic for the treatment of bacterial infections in the pediatric field.
