Studies were carried out on the penetration of cefuzonam (L-105, CZON), a new synthetic cephalosporin antibiotic, into cerebrospinal fluid, and on the clinical efficacy against bacterial infections. The results are summarized as follows: Concentrations of CZON in cerebrospinal fluid at 1 hour after intravenous administration of 100 mg/kg in cases of furunculosis of the external canal, encephalitis and mumps meningitis were 0.56 micrograms/ml, 1.44 micrograms/ml and 0.33 micrograms/ml, respectively. Concentrations of CZON in cerebrospinal fluid at 1 hour after intravenous administration of 100 mg/kg in 3 cases of purulent meningitis were 2.80-6.40 micrograms/ml at the acute stage and 0.56-1.45 micrograms/ml even at the recovering stage. Sensitivities of clinically isolated strains to CZON were determined and expressed as MIC. MICs of CZON on Haemophilus influenzae, Escherichia coli, Proteus mirabilis and Klebsiella pneumoniae were similar to MIC's of cefmenoxime (CMX), and lower than those of cefoperazone (CPZ), cefmetazole (CMZ), cefatiam (CTM) and Cefazolin (CEZ). The MIC of CZON on Staphylococcus aureus was similar to those of CEZ, CMZ and CTM, and lower than those of CMX and CPZ. Clinical responses of CZON were good in 2 cases of purulent meningitis, good in 2 cases of pyothorax, excellent in 1 case of septicemia, excellent in 3 cases of urinary tract infections, excellent in 7 cases and good in 3 cases out of 10 cases of pneumonia. Clinical responses of other diseases were excellent in 4 cases of bronchitis, good in 1 case of furunculosis of the external canal, excellent in 1 case of tonsillitis. No side effects nor abnormal laboratory findings were observed except 2 cases of mild diarrhea out of 24 cases.

Clinical studies on ceftizoxime, a new cephalosporin, were carried out in our department. The following results were obtained. 1. Antibacterial activity. Antibacterial activity of ceftizoxime against 7 strains of E. coli, 6 strains of Klebsiella, 6 strains of H. influenzae, 7 strains of E. cloacae and 10 strains of S. aureus, recently isolated from patients, was compared with that of cefotiam, cefmetazole and cefazolin. Ceftizoxime was more active than the other antibiotics against E. coli, Klebsiella, H. influenzae and E. cloacae, but less active against S. aureus. 2. Urinary excretion. Urinary excretion was measured in 2 cases with normal renal function after dosing with 750 mg (35 mg/kg) and 350 mg (17 mg/kg) of ceftizoxime by intravenous injections. Urinary recovery rates within 6 hours were 97% and 82% respectively. 3. Clinical study. Eighteen children with the following bacterial infections were treated with ceftizoxime; respiratory tract infection (13), acute otitis media (1), acute intervertebral chondritis and tonsillitis (1), chronic cystitis (1), subcutaneous abscess (1) and chronic bacteremia (1). The dosage was 69--147 mg/kg q.i.d. by intravenous injection. The duration of administration was from 3 to 32 days. The clinical results were excellent in 4 cases, good in 13 cases and fair in 1 case of chronic bacteremia. The overall effectiveness rate was 94%. Slight elevation of GPT in 1 case and leukopenia (neutropenia) in 1 case were observed, but returned to the normal range immediately after discontinuation of dosing. It is considered that ceftizoxime is one of the useful first choice antibiotics used for children with bacterial infections.

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.

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.

1. MIC of 6059-S against 92 strains of clinically isolated bacteria were measured. The compound was active against most of Gram-negative rods, but was not active against Staphylococcus aureus. 2. 20 mg/kg of 6059-S (newly synthesized oxacephem antibiotics) was administered to the pediatric patients and its blood concentration was measured by agar well method using E. coli 7437 as a test organism. 3. The mean blood concentrations were maximum at 15 minutes after intravenous one-bolus injection. Maximum levels were 94.5 mcg/ml in the patients of below 5 years old and 98.7 mcg/ml above 6 years old. Their half-life of the blood levels were 95.4 and 110.6 minutes respectively. 4. The mean blood concentrations were highest at the end of the infusion in the cases of 60 minutes drip injection. Maximum levels were 85.0 mcg/ml in the patients of below 5 years old and 64.8 mcg/ml above 6 years old. 5. Clinical efficacy of 6059-S in 6 cases pyelonephritis, 2 cases of sepsis, 1 case of meningitis, 1 case of intraperitoneal abscess, 9 cases pneumonia and 2 case of tonsillitis was 100%. In the case of urinary tract infection, 4 patients were treated successfully by the administration of 20 mg/kg/day of 6059-S. Other bacterial infections were treated with 55 to 200 mg/kg/day. 6. 100% of the causative organisms were eliminated by 6059-S. They were E. coli, Klebsiella pneumoniae, Serratia marcescens, H. influenzae and beta-Streptococcus. 7. No remarkable side effect was noticed during administration.

Ceftezole (CTZ) was administered to 20 patients with hematopoietic malignancy complicated with infections. These patients consisted of 7 cases of AML, 2 ALL, 2 AMMoL, 1 APL, 1 blast crisis of CML, 2 HD, and 5 NHL. In 13 cases, sites of infection were determined and causative organisms were identified. In other 7 cases, sites of infection or causative organisms were unknown. In the former 13 cases, pneumonia was demonstrated in 6 patients, tonsillitis in 4 patients, pyelonephritis in 2 patients and sepsis in 1 patient. Klebsiella was separated from 5 patients as the causative organisms, E. coli from 2 patients, E. coli and Pseudomonas aeruginosa from 1 patient, Pseudomonas cepacia from 1 patient, Streptococcus viridans from 2 patients, Proteus from 1 patient and Torulopsis from 1 patient. Gram-negative rods were separated from 10 of the 13 cases (77%) as the causative organisms. CTZ was administered intravenously in dose from 4 g to 16 g per day combined with other antibiotics (AMK, GM, DKB, TOB, SBPC, CBPC, LC, ST). The response rate in 12 cases of acute leukemia and in 7 cases of malignant lymphoma was 58% and 43%, respectively. Infections occurred in 4 patients with less than 100 neutrophil per mm3 did never favorably responded even with CTZ.

Fundamental and clinical studies were made on cefadroxil, a new oral cephalosporin, and the following results were obtained. (1) Antibacterial activity of the drug against S. aureus, S. epidermidis, E. coli, Klebsiella, Salmonella and P. mirabilis was almost equal to that of cephalexin. The MIC of indole positive Proteus. Enterobacter, Citrobacter, S. marcescens and P. aeruginosa to cefadroxil was higher than 100 microgram/ml in almost all strains. (2) Serum concentrations following an oral administration of 10.0 to 14.3 mg/kg of cefadroxil dry syrup was highest at 2 hours in 2 cases and 1 hour in 1 case, respectively, which were 13.4 to 17.1 microgram/ml, and 1.8 to 6.8 microgram/ml at 4 hours with an T 1/2 of 1.04 to 1.62 hours and apparently longer continuation of serum concentration than that of cephalexin. Urinary recovery rate was 75-96% up to 6 hours. (3) Fourteen patients, i.e., 6 with tonsillitis and 8 with urinary tract infection, were treated with a daily oral dose of 30-50 mg/kg divided in 4 doses except 1 case divided in 3 doses. The overall efficacy rate was 100%, i.e., excellent in 13, good in 1 and no failure. Causative organisms disappeared in all cases. (4) Adverse reactions, such as diarrhea and skin rash, were not noted at all and 1 case presented a mild elevation of GOT and GPT. (5) Taste and flavor of the drug was well palatable to children. (6) Based on the above results, it is concluded cefadroxil dry syrup is a new potent cephalosporin for oral use in the treatment of acute bacterial infection in children. Daily dose of 40 mg/kg in 3-4 divided doses appeared to be appropriate.

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 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.
