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.

The pharmacokinetics and the clinical effectiveness of meropenem (MEPM) were examined in the field of pediatrics. The results are summarized as follows. 1. A 4-year-6-month-old girl with suppurative meningitis (Haemophilus influenzae) was treated by intravenous drip infusion of MEPM in a daily dose of 29 mg/kg which was divided into 4 dosages, each dosage being infused over 30 minutes, and the drug concentration in cerebrospinal fluid was determined. Upon completion of infusion on the 2nd day of treatment, the drug concentration was 2.52 micrograms/ml, which corresponded to 3.6% of the drug concentration in the blood. 2. MEPM was used in 10 patients, including 3 with suppurative lymphnoditis, 2 with staphylococcal scalded skin syndrome (SSSS) and 1 each with pneumonia, suppurative meningitis, suppurative knee arthritis, facial phlegmon and pyelonephritis. The daily doses ranged from 30 to 117.6 mg/kg, divided into 3 to 4 dosages and administered via intravenous drip infusion over 30 minutes. Clinical responses were evaluated as very good in 7 patients, good in 2 patients and fair in 1 patient, with an efficacy rate of 90%. 3. Isolated pathogens were 2 strains of Staphylococcus aureus, 1 strain of Klebsiella pneumoniae and 3 strains of Haemopilus influenzae. All of the 6 strains were eradicated, with an eradication rate of 100%. 4. In the safety evaluation, none of the patients was observed to have any side effects. Furthermore, no abnormal variations were found in laboratory test data possibly attributable to administration of MEPM.

We conducted a study on the pharmacokinetics and clinical application of cefpirome (CPR) in children. 1. A single intravenous injection of 20 mg/kg of CPR was given to a two-month-old boy, and the concentration of the drug in the blood was measured. Fifteen minutes after administration, the concentration was 53.3 micrograms/ml, and it gradually decreased thereafter, reaching a level of 5.18 micrograms/ml after 8 hours with a half-life in the plasma of 2.36 hours. 2. A single intravenous injection of 700 mg (50 mg/kg) of CPR and that of cefotaxime (CTX) were given to a girl with suppurative meningitis (3 years old, 14 kg, causative bacteria, Haemophilus influenzae), and concentrations of the drugs in plasma and cerebrospinal fluid after 1 hour were measured. On the second day of illness, the concentration of CTX in the plasma was 39.4 micrograms/ml and the concentration of desacetyl-CTX (D-CTX) was 25.2 micrograms/ml, while concentrations in the cerebrospinal fluid were 6.22 micrograms/ml (15.8%) for CTX and 3.94 micrograms/ml (15.6%) for D-CTX. On the third day of illness, concentration of CPR in the plasma was 59.3 micrograms/ml, while its concentration in the cerebrospinal fluid was 7.44 micrograms/ml (12.5%). 3. CPR was intravenously administered in daily dosages of 37.7-75.0 mg/kg in 2-3 portions for periods of 4-15 days to 2 patients with septicemia (causative bacteria, Klebsiella pneumoniae in 1 case and Escherichia coli in the other), 1 patient with bronchitis (K. pneumoniae), 9 patients with pneumonia (1 case of Staphylococcus aureus, 3 cases of H. influenzae, 2 cases of Haemophilus parainfluenzae, 1 case of K. pneumoniae + Pseudomonas cepacia, 2 cases of H. influenzae + Branhamella catarrhalis), 2 patients with cellulitis (1 case of S. aureus, 1 case, causative agent unknown), 1 patient with suppurative lymphadenitis (causative agent, unknown), 1 patient with staphylococcal scalded skin syndrome, 1 patient with renal abscess (causative agent, unknown), and 1 patient with a urinary tract infection (E. coli), for a total of 18 patients, with excellent results in 9 cases and good results in 9 cases, hence an efficacy rate of 100% was obtained. 4. As an accompanying side-effect, eruption was observed in 1 of the 18 patients, but when administration was discontinued, the symptom gradually receded, and it disappeared by the 4th day.(ABSTRACT TRUNCATED AT 400 WORDS)

We have carried out laboratory and clinical studies on rokitamycin (RKM, TMS-19-Q). The results are summarized as follows. Serum and urinary concentrations of RKM were determined in 6 children with ages between 6 and 12 years given single oral doses of 5, 10 and 15 mg/kg. Mean serum concentrations peaked at 30 minutes after administration of 5, 10 and 15 mg/kg, and respective peak values were 0.30 microgram/ml, 0.79 microgram/ml and 1.32 micrograms/ml. Biological half-lives for 5, 10 and 15 mg/kg were 2.0 hours, 1.65 hours and 1.36 hours. The 6-hour urinary recovery ranged from 1.11% to 2.58% after administration of 5 mg/kg, and the mean 6-hour urinary recoveries were 1.35% after administration of 10 mg/kg and 2.28% after administration of 15 mg/kg. Therapeutic responses were recorded as excellent or good in 22 (73.3%) of the children, comprising 6 with tonsillitis, 2 with pharyngitis, 4 with bronchitis, 1 with bronchopneumonia, 1 with Mycoplasma pneumonia, 2 with whooping cough, 5 with streptococcal infections, 5 with Campylobacter enteritis, 3 with impetigo and 1 with SSSS. The microbiological effectiveness of RKM on identified pathogens comprising 4 strains of Staphylococcus aureus, 1 strain of Streptococcus pneumoniae, 6 strains of Streptococcus pyogenes, 4 strains of Haemophilus influenzae and 5 strains of Campylobacter spp. was not so satisfactory as evidenced by a eradication rate of 50.0%. No significant side effect due to the drug was observed in any cases. In conclusion, RKM was found to be efficacious and safe for the treatment of bacterial infections in children.

Pharmacokinetic and clinical studies were conducted to evaluate cefuzonam (L-105, CZON), a new cephem type antibiotic, in the pediatric field. A total of 9 pediatric patients (2-14 years) was treated with intravenous injection of CZON: 4 cases with one shot of 20 mg/kg, 2 cases with one shot of 40 mg/kg and 3 cases with drip infusion over 1 hour of 40 mg/kg. CZON concentrations in serum and the excretion in urine were determined. Mean serum concentrations of CZON after one shot intravenous injection of 20 mg/kg were 49.0, 22.7, 9.03, 2.13, 0.37, and 0.09 micrograms/ml at 15, 30 minutes, 1, 2, 4 and 6 hours, respectively. With 40 mg/kg one shot intravenous injections, mean serum concentrations were 117.5, 68.0, 26.2, 8.80, 0.63 and 0.19 micrograms/ml at 15, 30 minutes, 1, 2, 4 and 6 hours, respectively. With 40 mg/kg intravenous drip infusions over 1 hour, mean concentrations were 57.1, 78.8, 12.9, 1.12 and 0.23 micrograms/ml at 30 minutes, 1, 2, 4 and 6 hours, respectively. Mean half-lives were 0.69 hour for 20 mg/kg one shot injections, 0.44 hour for 40 mg/kg one shot injections, and 0.58 hour for 40 mg/kg 1 hour drip infusions. Urinary recovery rates in 6 hour after administration were 70.8% (mean) for the 20 mg/kg one shot injection, 44.1% (1 case) for the 40 mg/kg one shot injection, and 60.0% (mean) for the 40 mg/kg 1 hour drip infusion. CZON was administered in 26 cases of pediatric infections, and the clinical efficacy, antibacterial activity, and side effects were evaluated. Of the 26 cases 2 were excluded for the reason of not having bacterial infection, and the remaining 24 cases were assessed. Included in the 24 cases were 16 cases of acute pneumonia, 2 cases of acute purulent lymphadenitis, and 1 case each of acute bronchitis, acute purulent otitis media, acute apical periodontitis, staphylococcal scalded skin syndrome (SSSS), acute pyelonephritis, and acute enteritis. Clinical efficacy evaluation showed 19 excellent cases and 5 good cases, with an efficacy rate of 100%. Bacteriologically, Staphylococcus aureus 1 strain, Streptococcus pneumoniae 1 strain, beta-Streptococcus 1 strain, Haemophilus influenzae 10 strains, Haemophilus parainfluenzae 1 strain, Proteus mirabilis 1 strain, and Campylobacter jejuni 1 strain were determined or assumed as pathogens, but all of them were eradicated.(ABSTRACT TRUNCATED AT 400 WORDS)

Ceftizoxime (FK 749, CZX) was evaluated in 24 children with a suspicion of bacterial infection. Of the 17 confirmed bacterial infections, 16 were shown to be effective (effective rate, 94.1%). The diagnosis included acute pharyngitis (2), pneumonia (6), staphylococcal empyema (1), cervical purulent lymphadenitis (2), acute enterocolitis (2), acute pyelonephritis (1), SSSS (1) and suspected septicemia (2). The etiological pathogens recovered were Streptococcus anginosus (1), Streptococcus pneumoniae (1), Staphylococcus aureus (2), Haemophilus influenzae (3), enteropathogenic Escherichia coli (1) etc. A case of suspected Pseudomonas aeruginosa septicemia was not effectively treated with CZX. The serum half-life of CZX was 1.36 hours after intravenous bolus infection. A cerebrospinal fluid level of CZX was 6.2 mcg/ml 1 hour after intravenous bolus injection of 1 g (23.8 mg/kg) in a child with inflamed meninges. No severe adverse reaction was encountered with the CZX therapy. The data suggest that CZX is an excellent candidate for the first choice parenteral antibiotic in the pediatric infections.

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.

Bacteriological, pharmacokinetic and clinical studies on SY5555 dry syrup (powder which is dissolved before use), a new penem antibiotic for oral use, were performed. The following results were obtained. 1. Antibacterial activities. MICs of SY5555, clavulanic acid/amoxicillin (CVA/AMPC), cefotiam (CTM), cefpodoxime (CPDX), cefaclor (CCL) and cefdinir (CFDN) were determined against clinically isolated Staphylococcus aureus, coagulase negative staphylococci, Streptococcus pneumoniae, Streptococcus pyogenes, Haemophilus influenzae, Moraxella catarrhalis, Escherichia coli and Enterobacter cloacae at a dose of 10(6) CFU/ml. MICs of SY5555 against S. aureus, CNS, S. pneumoniae, S. pyogenes, H. influenzae, M. catarrhalis, E. coli and E. cloacae were 0.2, 0.2, 0.2, < or = 0.025, 0.78, 0.2, 0.78 and 3.13 micrograms/ml, respectively, showing excellent antibacterial effects on these pathogens. Although the effects of SY 5555 against H. influenzae and E. coli were slightly inferior to those of CPDX and CFDN, the drug showed the most excellent antibacterial effect on other strains as compared with the control drugs. 2. Absorption and excretion In this study, plasma concentrations and urinary recovery rates were examined after administration of SY5555 at doses of 5 and 10 mg/kg (potency) after meals. With both 5 and 10 mg/kg doses, peak plasma concentrations were reached 1 hour after administration, at 0.25-2.61 micrograms/ml (mean 1.47 micrograms/ml) and 1.08-2.17 micrograms/ml (mean 1.74 micrograms/ml), respectively. The plasma levels rapidly decreased to 0.06-0.19 micrograms/ml (0.12 micrograms/ml) and 0.0503-0.0637 micrograms/ml) after 6 hours. The half-lives 1.12 hours in the 5 mg/kg group and 1.0 hour in the 10 mg/kg group. The urinary recovery rates were determined in the first 8 hours after administration in the 5 mg/kg and 6 hours in the 10 mg/kg group, and the values were as low as 1.05-12.3% and 1.6-4.33%, respectively. 3. Clinical results The clinical responses were examined in a total of 73 cases including 4 acute pneumonia, 13 acute bronchitis, 11 tonsillitis, 3 pharyngitis, 12 scarlet fever, 2 pertussis, 6 urinary tract infection, 6 otitis media, 7 lymphadenitis, 2 staphylococcal scalded skin syndrome, 2 phlegmon, 4 impetigo and 1 purulent parotitis. The treatment was effective or better in 66 of 70 cases with an efficacy rate of 94.3% (3 undeterminable cases were excluded). Bacteriological effects were examined during the clinical course for detected or suspected pathogens found before administration of SY5555. The effects were determined in 50 cases including 7 cases of polymicrobacterial infections, 57 strains in total. Eight strains, however, persisted, hence the overall eradication rate was 86.0%.(ABSTRACT TRUNCATED AT 400 WORDS)
