Ceftriaxone (Ro 13-9904, CTRX), developed by F. Hoffmann-La Roche Ltd. in Switzerland, was used for the pediatric infections and the following results were obtained. The mean blood level of CTRX in 2 children after a 60-minute intravenous drip infusion with 20 mg/kg was 58.6 micrograms/ml at 30 minutes, 75.0 micrograms/ml at 1 hour, 39.85 micrograms/ml at 2 hours, 27.74 micrograms/ml at 4 hours, 20.71 micrograms/ml at 6 hours, 11.72 micrograms/ml at 12 hours and 3.91 micrograms/ml at 24 hours while the half-life time was 5.9 hours in one child and 7.6 hours in the other. CTRX was used in 22 children with acute infections consisting of 3 with acute pharyngeal tonsillitis, 4 with acute bronchitis, 8 with bronchopneumonia, 6 with infections of skin soft tissue and 1 with salmonellosis. The results were excellent in 5 cases and good in 17, indicating an efficacy rate of 100%. Out of 10 cases where the causative strains were detected, 4 cases were followed about the activities of the respective bacteria, i.e., H. influenzae, Streptococcus group A, S. aureus and Salmonella group B, all of which were eradicated after the end of administration. The daily dose of CTRX ranged from 30 to 50 mg/kg and generally a larger dose was used for serious infections. CTRX was administered twice daily in 20 out of 22 cases, by an intravenous injection in 4 and an intravenous drip infusion in 18, for 2 to 4 days in 16 and 5 to 8 1/2 days in 6. No clinical adverse reactions were observed while the laboratory test found a slight elevation of GOT in one and that of GOT and GPT in another. From the above results, CTRX was judged to be a highly useful drug for treatment of pediatric infections.

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.

Laboratory and clinical studies were performed as follows on ceftizoxime (CZX), a new cephalosporin antibiotic. 1. Susceptibility of clinically isolated bacteria to CZX and cefotiam (CTM) or sulbenicillin (SBPC). Antibacterial activities of CZX and CTM were compared against S. aureus, E. coli, K. pneumoniae, E. cloacae, H. influenzae and E. aerogenes; CZX was compared with SBPC against Ps. aeruginosa. CZX and CTM were nearly equal in activity against S. aureus, but CZX was found to be more active than CTM by 1--10 tubes against E. coli, K. pneumoniae, E. cloacae, H. influenzae and E. aerogenes. Against Ps. aeruginosa, CZX and SBPC were nearly equal in activity. 2. Serum concentration and urinary recovery. Serum concentrations of CZX were measured in 6 patients given CZX for prophylactic purpose during cardiac catheterization. In 2 patients given 20 mg/kg of CZX intravenously, the average serum concentration was 38.9 micrograms/ml at 30 minutes after intravenous bolus injection. In 3 patients given 10 mg/kg of CZX by intravenous drip infusion, the peak average serum concentration was 28.1 micrograms/ml at the end of infusion. Urinary recovery in 2 patients tested was 81.1% and 92.5% until 6--7 hours after intravenous bolus injection. 3. Clinical efficacy. CZX was given intravenously to 24 patients in doses of 30--111 mg/kg (57.1 mg/kg on an average) t.i.d. or q.i.d. for 3--16 days (5.5 days on an average): 1 with lacunar tonsillitis, 4 with acute bronchitis, 12 with pneumonia, 2 with enterocolitis, 2 with soft tissue infection, 2 with lymphadenitis and 1 with UTI. The overall efficacy rate was 95.8%, i.e., efficacy was excellent in 10 (41.7%), good in 13 (54.2%), and poor in 1 (4.2%). Bacteriological efficacy was excellent, i.e. 21 of the 23 strains disappeared. One patient had mild and transient diarrhea, but no other laboratory abnormalities were observed during treatment. The above results suggest that CZX is 1 of the most useful antibiotics for treating pediatric infections, especially due to Gram negative bacteria.

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.

Laboratory and clinical studies were performed on cefmenoxime (CMX), a new cephalosporin antibiotic, and the following results were obtained. 1. Susceptibility of clinically isolated bacteria to CMX and cefotiam (CTM) or cefazolin (CEZ) Antimicrobial activity of CMX was compared with that of CTM and CEZ against S. aureus, S. epidermidis, S. pneumoniae, H. influenzae and E. coli. CEZ and CTM were more active than CMX against S. aureus, S. epidermidis and S. pneumoniae. But CMX was found to be more active by 1-10 tubes than CEZ and CTM against H. influenzae and E. coli. 2. Clinical efficacy. CMX was intravenously administered to 19 patients; 3 with lacunar tonsillitis, 2 with acute bronchitis, 8 with bronchopneumonia, 3 with UTI, 1 with septicemia, 1 with acute panperitonitis, 1 with S.S.S.S. at daily doses of 30-115 mg/kg (64.6 mg/kg on an average) t.i.d. or q.i.d. for 3-17 days (6.1 days on an average). The overall efficacy rate was 94.7%, i.e., efficacy was excellent in 10 cases (52.6%), good in 8 cases (42.1%), and poor in 1 case (5.3%). Bacteriological efficacy was good, i.e. 16 of the 19 strains disappeared. Transient eosinophilia was observed in 1 patient, but no other laboratory abnormality was observed during treatment. The above results suggest that CMX is 1 of the useful antibiotics in treatment of pediatric infections, especially due to Gram negative bacteria.

Cephalexin, a semisynthetic cephalosporin antibiotic, has wide clinical application in respiratory infections of children and adults. In pharyngitis and tonsillitis due to beta-haemolytic streptococci, it is comparable to penicillin, cyclocillin, and cephaloglycin, as measured by clinical response, bacteriological cure rate, and incidence of relapse and reinfection. In otitis media, it is effective at dosages of 50-100 mg/kg/day except in those infections caused by Haemophilus influenzae, in which there is failure in 50% of the cases. In other infections of the upper respiratory tract, it appears to be effective except, again, in those caused by H. influenzae. Dosages of 1-2 g/day have been used in adults and 20-100 mg/kg/day in children. Adverse effects, mostly gastrointestinal upsets, rash, and urticaria, have been relatively infrequent and have not required discontinuance of the drug.

Laboratory and clinical studies on ceftazidime ( CAZ ), a new cephem antibiotic, were carried out in the field of pediatrics. The results were as follows: Antibacterial activities of CAZ against clinically isolated strains of S. pneumoniae, H. influenzae, E. coli and P. aeruginosa were compared with those of cefotaxime (CTX), ceftizoxime (CZX), latamoxef ( LMOX ), cefoperazone (CPZ) and cefmetazole (CMZ), and also with cefsulodin (CFS) and gentamicin (GM) against P. aeruginosa. Against S. pneumoniae and H. influenzae, CAZ was almost as active as CTX, CZX and CPZ. Against E. coli, it was almost as active as CTX, CZX and LMOX . Against P. aeruginosa, it was almost as active as CFS and GM. Serum concentrations and urinary excretion rates after intravenous bolus injection of CAZ at doses of 20 mg/kg and 10 mg/kg for 5 minutes in each 2 cases (4 cases in total) were determined. The mean serum concentrations of CAZ were 78.9 and 52.0 micrograms/ml at 15 minutes, 38.5 and 27.4 micrograms/ml at 1 hour, and 6.5 and 4.8 micrograms/ml at 4 hours, with serum half-lives (T 1/2) of 1.39 and 1.80 hours respectively. Mean cumulative urinary excretion rate within 6 hours after administration was 84.6%. In a patient with chronic renal failure, serum half-life was 3.22 hours and urinary excretion rate within 6 hours was 22.8% (after intravenous bolus injection of CAZ at a dose of 10 mg/kg). CAZ was administered at a dose of 55.5 mg/kg by intravenous bolus injection to a child with purulent meningitis. The levels of CAZ in the cerebrospinal fluid (CSF) at 1 hour after administration were 2.7-38.9 micrograms/ml with CSF/Serum ratios of 3.2-28.8%. Forty-two pediatric patients with various bacterial infections (pyelonephritis 14, tonsillitis 1, bronchopneumonia 3, pneumonia 17, purulent meningitis 1, bacteremia 2, SSSS 1, enterocolitis 3) were treated with CAZ at a daily dose of 49-222 mg/kg t.i.d. or q.i.d. (as a rule 60 mg/kg t.i.d.). The efficacy rate was 97.6% clinically and 97.8% bacteriologically. No adverse reactions were observed except 1 case with mild diarrhea. Abnormal laboratory findings were also only mild; eosinophilia in 1, slight elevation of GOT in 5 and that of GOT & GPT in 3 cases. These results indicate the usefulness of CAZ in the treatment of bacterial infections in children.

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.

Laboratory and clinical studies were performed on 6059-S in the field of pediatrics, a new semi-synthetic 1-oxacephem antibiotic, and results were as follows. 1. MICs of 6059-S were compared with those of cefazolin (CEZ) and cefmetazole (CMZ) on 31 strains of S. aureus, 29 strains of E. coli, 30 strains of K. pneumoniae and 16 strains of P. aeruginosa. With the inoculum size of 10(8) cells/ml an 10(6) cells/ml, the peak of distribution of MICs were S. aureus 6.25, 3.13 micrograms/ml, E. coli 0.2, 0.1 micrograms/ml, K. pneumoniae 0.2, 0.05 micrograms/ml and P. aeruginosa 12.5, 6.25 micrograms/ml, respectively. MICs 6059-S against S. aureus was more less 2 to 3 tubes than CEZ and CMZ, but against E. coli and K. pneunoniae were more higher than 3 to 4 tubes than CEZ and CMZ. 2. The serum concentrations and urinary recovery rate of 6059-S were measured in 5 pediatric patients. 6059-S was given 20 mg/kg by an intravenous injection to 2 cases or a 30 minutes intravenous drip infusion to 3 cases. The mean concentration of the former were 64.3, 44.3, 26.8, 11.7 and 5.0 micrograms/ml at 0.5, 1, 2, 4 and 6 hours, and T 1/2 was 1.51 hours. The urinary recovery rates was 75.0% within 6 hours after the injections. The mean concentration of the latter were 65.3, 86.3, 63.0, 40.3, 17.8 and 8.9 micrograms/ml at 0.25, 0.5, 1, 2, 4 and 6 hours, and T 1/2 was 1.63 hours. The urinary recovery rates was 52.1% within 6 hours after the injection. 3. Eleven cases with acute pneumonia, 1 case with acute bronchitis, 3 cases with acute purulent tonsillitis, 1 case with acute purulent parotitis and 1 case subcutaneous abscess were treated with 6059-S by intravenous injection. All cases were above effective clinically. Five strains of H. influenzae, 3 strains of S. pneumoniae, 2 strains of S. pyogenes and 1 strain of S. aureus were eradicated in all strains. No clinical adverse reaction and abnormal laboratory findings were noted.
