Clinical efficacy and safety of cefprozil (CFPZ, BMY-28100), a newly developed oral cephalosporin, were studied in our pediatric department. Clinical effectiveness, bacteriological effectiveness and side effects were studied in 116 pediatric patients with ages ranging 4 months to 11 years. CFPZ was given 4.6-14.1 mg/kg daily in 3 times for 3-10 days. Clinical efficacies were evaluated in 112 patients, and the therapeutic effectiveness were excellent in 1 and good in 6 for 7 patients with acute pharyngitis, excellent in 24 and good in 26 for acute purulent tonsillitis, excellent in 3, good in 8 and fair in 1 for acute bronchitis, excellent in 21, good in 7, fair in 1 and poor in 1 for acute pneumonia, excellent in 1 acute purulent parotitis, excellent in 2 and good in 7 for acute UTI, good in 1 impetigo, fair in 1 periproctal abscess and good in 1 acute enteritis. The effectiveness rate was 96.4%. Bacteriologically, 4 strains of Staphylococcus aureus (beta-lactamase producing strains), 1 strain of Staphylococcus epidermidis (beta-lactamase producing strain), 2 strains of Streptococcus pneumoniae, 2 strains of Streptococcus agalactiae, 4 strains of beta-Streptococcus, 1 strain of Klebsiella pneumoniae (beta-lactamase producing strain) and 1 strain of Salmonella C2 were all disappeared, and of 22 strains of Streptococcus pyogenes, 20 strains were disappeared, 1 was decreased and 1 was unknown, of 5 strains of Escherichia coli (3 beta-lactamase producing strains), 4 were disappeared and 1 was decreased, of 29 strains of Haemophilus influenzae (14 beta-lactamase producing strains), 14 were disappeared, 11 were decreased, 3 persisted and 1 was unknown and of 2 strains of Haemophilus parainfluenzae (1 beta-lactamase producing strain), 1 was disappeared and 1 persisted. The bacteriological eradication rates for Gram-positive bacteria and Gram-negative bacteria were 97.1% and 56.8%, respectively, and the drug was especially effective against Gram-positive bacteria. No side effects nor refusal of ingestion were observed. As abnormalities in laboratory test results, 3 cases of elevation of eosinophil counts and 1 of elevation of platelet counts were observed. In conclusion, CFPZ was considered to be a safe and highly effective antibiotic in pediatric infections.

Pharmacokinetic and clinical evaluations in pediatrics were made on meropenem (SM-7338, MEPM), a new parenteral dehydropeptidase-1 stable carbapenem used without any inhibitors, at 33 medical institutions. The results are summarized as follows. 1. Pharmacokinetic studies. MEPM at a dose of 10, 20, or 40 mg/kg was administered to 53 children by 30-minute drip infusion. Peak plasma concentrations (Cmax's) and plasma half-lives (T1/2's) of these doses were 28.5, 47.2 and 130.0 micrograms/ml, and 0.80, 0.93 and 0.94 hours, respectively. A clear dose response was observed in Cmax's and T1/2 values were quite similar to those observed in adults. In the first 6 hours after administration, 54.4 to 68.1% of the administered drug was recovered in urine. The cerebrospinal fluid (CSF) levels of MEPM in patients with purulent meningitis were 0.13 microgram/ml at a dose of 6 mg/kg, and 0.64 to 4.22 micrograms/ml at a dose of 29 to 44 mg/kg within day 4 of onset. The penetration rate of MEPM showed an intermediate value among those for other cephalosporin antibiotics. 2. Clinical study. Clinical efficacies of MEPM were evaluated in 389 cases. The most common doses used were 10 to 20 mg/kg/once, 2 to 3 times a day. The maximum dose was 173 mg/kg/day q.i.d. MEPM gave "excellent" or "good" responses in 242 (97.6%) out of 248 cases in which causative organisms were documented and in 134 (95.0%) out of 141 cases in which causative organisms were not identified. Clinical efficacy rates were 100% in 11 patients with purulent meningitis, 85.7% in 7 with septicemia, 98.8% in 173 with pneumonia, and 100% in 65 with UTI. Bacteriologically, 260 strains (96.7%) out of 269 strains were eradicated by MEPM treatment. Eradication rates were 89.2% for Staphylococcus aureus (37 strains) and 100% for Streptococcus pneumoniae (35 strains). The overall eradication rate for Gram-positive bacteria was 94.6%. Among Gram-negative bacteria, 98.3% out of 172 strains were eradicated. The eradication rate of Haemophilus influenzae (73 strains) was 98.6% and Pseudomonas aeruginosa (11 strains) was 90.9%, and all of Branhamella catarrhalis (15 strains), Escherichia coli (42 strains), and Klebsiella pneumoniae (6 strains) were eradicated. Out of 84 cases for which previous antibiotic therapies of 3 days or longer were not successful, MEPM gave "excellent" or "good" responses in 77 cases (91.7%) and excellent bacteriological responses (95.7%).(ABSTRACT TRUNCATED AT 400 WORDS)

Bacteriological and clinical studies have been performed on meropenem (MEPM, SM-7338), a newly developed carbapenem antibiotic, in the pediatric field. 1. Antibacterial activities of MEPM against 24 clinical isolates were determined. MEPM showed excellent activity against Gram-positive bacteria including Staphylococcus aureus and Gram-negative bacteria, especially Escherichia coli and Branhamella catarrhalis. Against Haemophilus influenzae, MEPM had a higher activity than imipenem and flomoxef, but had a lower activity than piperacillin and cefoperazone. 2. Clinical efficacies of MEPM were evaluated in 32 cases with bacterial infections. A poor efficacy was observed in 1 patient with phlegmon but excellent or good efficacies were obtained in other 31 patients with tonsillitis (1), pneumonia (17), UTI (12), or SSSS (1). The overall efficacy rate was 96.9%. All strains except 1 of S. aureus were eradicated by the administration of MEPM, and a high eradication rate of 95.8% (23 out of 24 strains) was obtained. 3. No side effects were observed in 35 evaluated cases. As abnormal laboratory test results, elevated GOT, elevated GPT, eosinophilia and neutropenia were noted in 4, 4, 4 and 2 patients, respectively. 4. Influences on blood coagulation parameters were studied. PIVKA II was elevated upon administration of MEPM in some cases, but no changes in ATT, TT, HPT or Fbg were observed during the treatment. Based on the above results, it has been concluded that MEPM is a safe and effective drug to use in the treatment of pediatric infections. The usual recommended dosage and administration should be 10 to 20 mg/kg of MEPM at a time, using intravenous drip infusion, 3 times a day.

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)

Fundamental and clinical studies on cefuzonam (L-105, CZON), a newly semisynthesized cephem antibiotic, were carried out in the field of pediatrics and the following results were obtained. Antibacterial activities of CZON against clinically isolated strains of Staphylococcus aureus, S. epidermidis, Streptococcus pneumoniae, S. pyogenes, Escherichia coli, Klebsiella pneumoniae, Haemophilus parainfluenzae and H. influenzae were compared with those of cefmenoxime (CMX), latamoxef (LMOX), cefoperazone (CPZ), cefmetazole (CMZ), cefotiam (CTM) and cefazolin (CEZ). CZON was nearly as active as CEZ against S. aureus and S. epidermidis and superior to other antibiotics against other Gram-positive cocci. Against Gram-negative rods, CZON was as active as CMX and superior to other 5 antibiotics compared. Serum concentrations and urinary excretion rates after intravenous bolus injection of CZON at doses of 10 mg/kg, 20 mg/kg and 40 mg/kg for 5 minutes in 1, 5 and 4 cases, respectively, were determined. Mean serum concentrations of CZON at these dose levels were 11.0, 43.8 and 111.5 micrograms/ml at 15 minutes, 2.4, 10.3 and 30.3 micrograms/ml at 1 hour and 0.17, 0.72 and 1.28 micrograms/ml at 4 hours, with serum half-lives of 1.79, 0.88 and 1.19 hours, respectively. Mean cumulative urinary excretion rates within 6 hours after administration were 47.9, 56.3 and 40.3%, respectively. Thirty-four pediatric patients with various bacterial infections (tonsillitis 2, acute bronchitis 1, pneumonia 14, pyothorax 1, sepsis 1, suppurative lymphadenitis 1, UTI 13 and enteritis 1) were treated with CZON at a daily dose of 40-94 mg/kg t.i.d. or q.i.d.. The overall clinical efficacy rate was 94.1%. No adverse reactions were observed except 2 cases with mild diarrhea. Abnormal laboratory findings were also mild; slight elevation of GOT and GPT in 2, eosinophilia in 1 and thrombocytosis in 1. These results clearly indicate the usefulness of CZON in the treatment of bacterial infections in children.

As a result of conducting experimental and clinical tests with the newly developed cephalosporin, cefoperazone (CPZ), the following conclusions were obtained: (1) When tested against 10 strains of Staphylococcus aureus and 16 strains of Staphylococcus epidermidis, the antibacterial activity of CPZ was found to be weaker than that of CEZ. Against 5 strains of A-beta-Streptococcus and 4 strains of Streptococcus pneumoniae, both CPZ and CEZ exhibited similar excellent antibacterial activity. CPZ was effective against 18 strains of Escherichia coli though its activity was influenced by the amount of inoculated bacteria present. Against 15 strains of Haemophilus influenzae and 10 strains of Haemophilus parahaemolyticus, CPZ was found to be more effective than CEZ though several high-resistant strains were noted. CPZ also showed more excellent antibacterial activity than CEZ against 4 strains of Haemophilus parainfluenzae, 5 strains of Klebsiella pneumoniae, 8 strains of Salmonella sp., 4 strains of Pseudomonas aeruginosa and 4 strains of Proteus sp. (2) The mean half-life in the blood following intravenous injections of 25 mg/kg and 10 mg/kg of CPZ to three children was 70 minutes. (3) One hour after intravenous injection of 25 mg/kg of CPZ to 3 cases of aseptic meningitis, drug concentration in the cerebrospinal fluid (CSF) was 1.20 mcg/ml, less than 0.39 mcg/ml and 1.55 mcg/ml. In one case, the CSF/serum ratio was 2.7%. (4) The average recovery rate in the urine of children who had received intravenous administrations of 25 mg/kg (3 children) and 10 mg/kg (1 child) was 17.8% between 0 and 6 hours. (5) Eighteen pediatric patients received CPZ in doses ranging from 48 to 170 mg/kg divided three-four times a day. They were RTI in 7, URI in 5, UTI in 5, SSSS in 1 and enteritis in 1 children. The clinical effectiveness of CPZ was judged to be remarkedly effective in 11 children, effective in 5 children and ineffective in 3 children, with an overall effective rate of 84.2%. One patient of tonsillitis combined sinusitis was considered 2 cases. The three cases in which the drug was found to e ineffective were 2 cases of pyothorax and 1 case of sinusitis. (6) Side effects were 1 case of eosinophilia, 2 cases of elevation of GOT and GPT, and 1 case of mild elevation of GOT. All were considered to be minor.

Pharmacokinetic and clinical studies on S-1108, a new oral cephem antibiotic, were performed in the field pediatrics. The following results were obtained. 1) Antibacterial activities Antibacterial activities of S-1006, the active form of S-1108, were studied against clinically isolated strains of (Staphylococcus aureus (n = 5), Streptococcus pneumoniae (n = 6), Streptococcus pyogenes (n = 3), Haemophilus influenzae (n = 8), Branhamella catarrhalis (n = 5) and Haemophilus parainfluenzae (n = 2). MIC values ranged < or = 0.025-1.56 for GPC and < or = 0.025-0.78 microgram/ml for GNR. 2) Absorption and excretion Blood concentrations and urinary excretion rates of S-1108 were measured upon administration of S-1108 after meal at dose of 3 mg/kg (n = 4), 4 mg/kg (n = 1) and 6 mg/kg (n = 1). The peak blood concentrations of S-1006 at a dose of 3 mg/kg (n = 4), ranged from 0.57 to 1.82 micrograms/ml at 1, 2 and 4 hours after dosing. Mean pharmacokinetic parameters T1/2 and AUC were 1.29 +/- 0.69 hours and 4.47 +/- 2.25 micrograms.hr/ml, respectively. At a dose of 4 mg/kg and 6 mg/kg, peak concentrations were 1.79 and 1.27 micrograms/ml at 2 and 3 hours after treatment. T1/2 and AUC were 1.34 and 1.11 hours, and 8.19 and 5.65 micrograms.hr/ml, respectively. Urinary recovery rates ranged from 13.0 to 37.2% for the first 8 hours after administration. 3) Clinical studies Clinical efficacies were examined in 32 cases of various pediatric infections including 5 cases of acute pneumonia, 11 cases of bronchitis, 2 cases of scarlet fever, 8 cases of tonsillitis, 1 case of pharyngitis, 2 cases of otitis media and 3 cases of UTI. Clinical efficacy rate was 96.9% (31/32) and bacteriological eradication rate was 87.1% (27/31).

Bacteriological, pharmacokinetic and clinical studies on cefditoren pivoxil (CDTR-PI, ME 1207) in granules, a new oral cephalosporin, were performed in the field of pediatrics. The results are summarized below. 1. Antibacterial activities: Antibacterial activities of CDTR were studied against Staphylococcus aureus, Streptococcus pneumoniae, Streptococcus pyogenes, Haemophilus influenzae, Haemophilus parainfluenzae and Branhamella catarrhalis in comparison with those of cefteram (CFTM), cefixime (CFIX), cefaclor (CCL), cefpodoxime (CPDX) and cefotiam (CTM). MIC80's of CDTR against S. aureus, S. pneumoniae, S. pyogenes, H. influenzae, H. parainfluenzae and B. catarrhalis were 1.56, 0.39, < or = 0.025, < or = 0.025, 0.05 and 0.20 micrograms/ml, respectively. These results showed that CDTR has high antibacterial activities against these organisms. 2. Absorption and excretion: Serum concentrations and urinary recovery rates of CDTR-PI (administered in granules) were determined. Upon single oral doses of 3 mg/kg and 6 mg/kg, the peak serum concentrations were 0.5-2.45 micrograms/ml at 2 to 4 hours and 1.79-4.05 micrograms/ml at 1 to 4 hours, respectively, and T 1/2 was 1.07-9.67 hours and 0.99-3.00 hours, respectively. At 8 hours after dosing, serum concentrations were 0-0.87 micrograms/ml with a dose of 3 mg/kg and 0.27-0.73 micrograms/ml with 6 mg/kg. These values indicated that the drug has a dose-dependent pharmacokinetic behavior. Urinary recovery rates in the first 8 hours were 12.9-34.2% with a dose of 3 mg/kg and 11.8-26.9% with 6 mg/kg. 3. Clinical study: Clinical efficacies were examined in a total of 81 cases consisting of 20 cases of acute bronchitis, 13 of acute pneumonia, 21 of tonsillitis, 5 of pharyngitis, 7 of scarlet fever, 2 each of impetigo, otitis media and purulent cervical lymphadenitis, 1 of pertussis and 8 of UTI. The clinical efficacy rate was 97.5% (79/81), and bacteriological eradication rate was 100% (76/76). As for side effects, 2 cases of watery stools and 1 case of minor elevation of GPT were observed.
