Bacteriological, pharmacokinetic and clinical studies on cefpirome (CPR, HR 810), a new cephem antibiotic, were carried out in the field of pediatrics. The results obtained are summarized below. 1. Antibacterial activities of CPR against clinically isolated strains of Staphylococcus aureus, Streptococcus pneumoniae, Streptococcus pyogenes, Streptococcus agalactiae, Escherichia coli, Klebsiella pneumoniae, Haemophilus influenzae and Haemophilus parainfluenzae were superior to those of ceftazidime. 2. Plasma concentrations and urinary excretion rates after intravenous bolus injection of CPR at doses of 10, 20 and 40 mg/kg for 5 minutes in 2 cases each were determined. Mean peak plasma concentrations of CPR at these dose levels were 33.9, 62.9 and 96.0 micrograms/ml at 15 minutes with plasma half-lives of 1.58, 1.69, and 2.13 hours, respectively. Mean cumulative urinary excretion rates in the first 8 hours after administration were 51.2, 78.0 and 74.9%, respectively. 3. Ten patients with bacterial infections (pneumonia 5 cases, urinary tract infection 5 cases) were treated with CPR at a daily dose of 16-79 mg/kg/day. The overall clinical efficacy and bacteriological eradication rates were both 100%. 4. No adverse reactions were observed except in 1 case of mild pain in blood vessels. Abnormal laboratory test results were also mild, slight elevation of GOT, GPT and thrombocytosis in 1 case and eosinophilia in 1 case.

Cefpirome (CPR, HR 810), a new cephem antibiotic, was investigated for its penetration into cerebrospinal fluid (CSF), and its clinical efficacy against bacterial infections. 1. CSF concentrations of CPR following intravenous injection was investigated in 2 patients with purulent meningitis. In one of them, the concentrations were 2.11 micrograms/ml and 1.31 micrograms/ml on 3 and 8 days, respectively, after start of administration. In the other patient, they were 24.2 micrograms/ml, and 1.35 micrograms/ml on 2 days and 7 days after administration, respectively. 2. Antibacterial activities of CPR against clinical isolates, Escherichia coli, Haemophilus influenzae, Staphylococcus aureus and Streptococcus pneumoniae, except those against Pseudomonas aeruginosa, were clearly superior to those of ceftazidime. 3. Clinical efficacies evaluated in 15 patients were "excellent" in 9, "good" in 5 and "unknown" in 1. The overall efficacy rate was 93.0%. 4. Clinical efficacies were "excellent" in 1 patient with bacteremia, "excellent" in 6 and "good" in one of 7 patients with pneumonia, and "good" in both of the 2 patients with purulent meningitis. Clinical efficacies against other diseases were "excellent" or "good", in 1 patient with pyothorax, 1 patient with purulent lymphadenitis, and 2 patients with facial cellulitis. In 1 patient with biliary tract infection, the results of treatment with CPR were "unknown" due to insufficient clinical data. 5. No adverse reactions were observed except in 1 patient who showed an increase in platelet count.

Cefpirome (HR 810, CPR), a new cephem antibiotic, was investigated for its experimental and clinical studies in pediatrics. The results obtained are summarized as follows. 1. Plasma and urinary levels of CPR were determined in 2 children (age 5 and 7 years) after the one shot intravenous injection of the drug at 20 mg/kg. Average plasma levels of the drug were 44.7 micrograms/ml, 28.5 micrograms/ml, 10.5 micrograms/ml, 4.6 micrograms/ml and 1.5 micrograms/ml at 1/2 hour, 1 hour, 2 hours, 4 hours and 6 hours, respectively, and the average half life was 1.57 hours. Average urinary levels of the drug were 1,785 micrograms/ml, 545 micrograms/ml and 198 micrograms/ml at 0-2 hours, 2-4 hours, 4-6 hours, respectively and the average urinary elimination rate was 52.0%. The results were nearly equivalent to those in adults except for urinary elimination rate which tended to be slightly lower than that in adults. 2. Cerebrospinal fluid levels in 3 cases of purulent meningitis treated with CPR were investigated. Cerebrospinal fluid levels in a case of Neisseria meningitidis were 11.5-23.1 micrograms/ml at 1 hour and 0.94 microgram/ml at 5 hours after intravenous injection of 44.4 mg/kg, 4 times a day. Cerebrospinal fluid levels in a case of Streptococcus pneumoniae were 1.01-4.23 micrograms/ml at 1 hour after intravenous injection of 49.0 mg/kg, 6 times a day, and in the other case with Streptococcus pneumoniae, the levels were 16.8-37.1 micrograms/ml at 1 hour, 11.3 and 3.60 micrograms/ml at 3 and 4 hours after intravenous injection 52.2 mg/kg, 6 times a day. These results are not inferior to those with cefotaxime or ceftriaxone. These levels appear to be higher than MIC90 values against Escherichia coli, Streptococcus agalactiae, S. pneumoniae or Haemophilus influenzae which are the major pathogens of these diseases. 3. CPR was given to 62 patients and clinical efficacy, bacteriological response and adverse reactions were evaluated. Evaluated cases for clinical efficacy included 3 cases of purulent meningitis, 1 case of acute purulent otitis media, 2 cases of acute purulent tonsillitis, 1 case of acute bronchitis, 49 cases of acute pneumoniae, 1 case of scarlet fever, 1 case of acute osteomyelitis, 1 case of acute enterocolitis, and 2 cases of acute UTI, totalling 61 cases. Clinical efficacies were excellent in 38 cases, good in 22 cases and fair in 1 case with an efficacy rete of 98.4% (excellent + good).(ABSTRACT TRUNCATED AT 400 WORDS)

A research group was organized with the purpose of making basic and clinical studies on cefpirome sulfate (HR810, CPR), a newly developed cephalosporin antibiotic, in the pediatric field. Through meetings a joint research was done involving 19 key institutions and their related facilities throughout Japan. The obtained results are summarized as follows. 1. Antibacterial Activities Minimum inhibitory concentrations (MICs) were determined against 71 Gram-positive and 110 Gram-negative bacteria in the present clinical trials. CPR showed antibacterial activities 2-16 times higher than those of ceftazidime (CAZ) against Staphylococcus aureus and other Gram-positive bacteria including MRSA. Against Gram-negative bacteria, CPR showed a somewhat broad range of distribution in MIC against Branhamella catarrhalis, while the antibiotic inhibited the growth of all the strains of Escherichia coli and Haemophilus influenzae at concentrations no more than 0.10 and 0.20 micrograms/ml, respectively. 2. Blood Concentrations and Urinary Excretion Rates The pharmacokinetics in pediatric patients was investigated with a dose of 20 mg/kg in most cases via one shot intravenous injection or 30- and 60-minute intravenous drip infusion. Mean blood concentrations of CPR at 15 minutes after one shot intravenous injection of 10, 20, and 40 mg/kg were 51.2, 70.5, and 123.5 micrograms/ml, with half-lives of 1.21, 1.39, and 1.53 hours, respectively. Urinary excretion rates in 6 hours were 63.6, 66.0 and 71.6%, respectively for the 3 dose levels. After 30- and 60-minute intravenous drip infusions at the same dose, the pharmacokinetic parameters observed were similar to those obtained with one shot injections. 3. Concentration in the Cerebrospinal Fluid CPR penetrated well into the cerebrospinal fluid in patients with purulent meningitis and levels of 1.85-24.2 micrograms/ml 45-60 minutes were achieved after intravenous injection at a dose of 40-80 mg/kg, the penetration rate of CPR was at an intermediate degree compared with other cephalosporin antibiotics. 4. Clinical Results Clinical efficacies of CPR on infectious diseases were analyzed in 454 plus 3 cases which were complicated with other infectious diseases, hence totaling 457 cases out of 499 cases originally chosen for clinical evaluation. The remaining 45 cases were excluded from the clinical evaluation. As for the clinical efficacy, CPR was found to be effective (good or excellent) in 430 (94.1%) of the 457 cases. CPR was found to be effective in 243 (95.3%) of 255 cases for which causative bacteria were identified. The efficacy rate was 92.6% (187 of 202) in those cases in which causative bacteria were not identified.(ABSTRACT TRUNCATED AT 400 WORDS)

Cefpirome (CPR, HR 810), a new parenteral cephalosporin antibiotic, was studied for its pharmacokinetics, bacteriological and clinical effects in the field of pediatrics. 1. CPR was very active against Staphylococcus aureus, Staphylococcus epidermidis, Coagulase-negative staphylococci, Streptococcus pneumoniae among Gram-positive cocci. Antibacterial activities of CPR were also strong against Branhamella catarrhalis, Haemophilus influenzae, Escherichia coli, Salmonella sp., Klebsiella oxytoca, Enterobacter cloacae, Pseudomonas aeruginosa among Gram-negative rods. 2. The plasma concentration 15 minutes after a bolus intravenous injection of 20 mg/kg was 80.4 micrograms/ml, and the T 1/2 (beta) was 1.03 hours. Plasma concentrations after intravenous drip infusion over 30 minutes of 20 mg/kg and 25 mg/kg were 48.3 and 117 micrograms/ml at the end of infusion, and T 1/2 (beta) for these dosage were 1.14 and 1.45 hours. 3. The urinary recovery rates over 6 hours after administration were 45.2-63.9% for CPR. 4. Clinical efficacies of CPR were excellent in 31 patients and good in 30 patients with an efficacy rate of 98.4%. In bacteriological examinations, causative organisms were eradicated with an eradication rate of 95.7%. 5. As side effects, diarrhea was observed in 5 patients and loose stool in 1 patient with an incidence of 8.2%. Abnormal values were found in some patients in clinical laboratory tests for eosinophilia, thrombocytosis and an elevation of GOT, GPT and triglyceride. These findings indicate that CPR will be useful against bacterial infections in pediatrics.

Pharmacokinetics and clinical effects of cefpirome (CPR, HR 810) in children were studied. When 20 mg/kg and 40 mg/kg doses of CPR were administered to 4 children through 30 minutes' drip infusion, half-lives were 1.23 +/- 0.23 (mean +/- S.D.) hours and 1.37 +/- 0.35 (mean +/- S.D.) hours, respectively for the 2 dose levels, and recovery rates in urine in the first 6 hours after administration were 74.8% and 56.1%, respectively. CPR was administered to 15 cases (3 tonsillitis, 3 bronchitis, 5 bronchopneumonia, 1 acute cystitis, 1 coxoiliatitis, 1 otitis media, 1 otitis externa). The efficacy rate was 86.7%. Seven strains of bacteria were isolated and identified 4 Haemophilus influenzae, 3 Staphylococcus aureus, 1 Pseudomonas sp. from these cases. These bacteria in children were followed after administration of CPR. Six strains were eradicated and one was reduced in number. No adverse effects of CPR were observed except in 2 cases, one of which showed transient eosinophilia and the other showed a transient increase of transaminase. These results suggest that CPR may be an effective and safe drug to use on children clinically.

The study dealt with etiological diagnostics of bacterial exacerbations of chronic obstructive pulmonary disease (COPD). Samples of bronchial secretion were obtained from 73 patients hospitalized in connection with COPD exacerbations and investigated by the culture method and PSR. The former technique revealed bacterial pathogens in 64 (82%) patients. Gram-positive bacteria (Streptococcus pneumoniae) predominated in patients with stage I and II COPD, Gram-negative (Pseudomonas aeruginosa) and mixt infection in those with stage III and IV COPD. CPR proved more sensitive for isolation of DNA of Gram-negative pathogens (Haemophilus influenzae and Enterobacteriaceae).
