Fundamental and clinical studies were carried out with aztreonam (AZT), a new monocyclic beta-lactam antibiotic, in pediatric infections. Results were as follows. The mean half-lives in the vein blood were 1.09 hours, 1.18 hours, 1.22 hours after injection, when the doses were 10, 20 and 40 mg/kg, respectively. Dose response was observed. The average recovery rates in the urine between 0 and 6 hours were 40.2%, 42.3%, 50.8% when the doses were 10, 20 and 40 mg/kg, respectively. The antibacterial activity of AZT against 16 clinical isolates were determined in comparison with those of ABPC, CPZ, LMOX and CTX. Against 8 clinical isolates of E. coli and 3 of H. influenzae, the activity of AZT was equal or superior to that of CPZ, LMOX and CTX, and way by far superior to that of ABPC. Twenty-three pediatric patients received AZT in doses ranging from 48 to 79 mg/kg divided 3 times a day; 12 cases of urinary tract infection, 9 cases of respiratory tract infection and 2 cases of bacterial enterocolitis. The rate of clinical effectiveness was 100%. No side effect was observed. Slight elevation of GOT and GPT were observed in 2 cases, increase of platelet count in 2. All were considered to be transient and mild.

Clinical studies of aztreonam (AZT) were performed in 10 pediatric cases. One transient pyuria case with 10(3)/ml E. faecalis detected in urine was excluded from clinical evaluation, because the presence of infection was unclear. Results were as follows: AZT was effective on 1 patient with meningitis (causative organism: H. influenzae), who was treated with 41.7 mg/kg 4 times a day. Results of administration of 58.1-78.9 mg/kg 3 or 4 times a day by intravenous injection for 1 E. coli sepsis-and-pyelonephritis complication case and 7 pyelonephritis cases (causative organisms: E. coli in 1, E. coli + E. faecalis in 1, E. faecalis in 1, P. aeruginosa in 3 and unknown in 1) were excellent in 4, good in 2 and poor in 2 cases. The pathogens of the 2 poor cases were E. faecalis and P. aeruginosa, respectively. Six of the pyelonephritis cases had vesicoureteral refluxes as an underlying condition. Clinical and microbiological effects of AZT were considered to be closely correlated with its MIC values. No side effect was recognized. Though abnormal laboratory findings were obtained in 4 cases, including elevations of GOT X GPT in 2 cases, GPT elevation in 1 case and plateletcount increase in 1 case. All of these abnormalities were minor and transient. The serum concentrations of AZT for a two-month-old patient with pyelonephritis were 65, 50, 35, 22.8 and 12.4 micrograms/ml at 1/2, 1, 2, 4 and 6 hours, respectively and T1/2 was 2.42 hours after injecting AZT 20 mg/kg by intravenous injection.(ABSTRACT TRUNCATED AT 250 WORDS)

Ceftriaxone (Ro 13-9904, CTRX), a new parenteral cephalosporin, was used for pediatric infections and the following results were obtained. CTRX was administered twice daily by intravenous injection with about 20 mg/kg in 6 cases consisting of 2 cases with purulent lymphadenitis of the neck, 2 with urinary tract infection, 1 with sepsis and pyelonephritis and 1 with sepsis and purulent lymphadenitis of the neck. The result was excellent in 4 and good in 2. One case with H. influenzae meningitis, receiving 50 mg/kg CTRX by intravenous injection twice daily, showed an excellent response without having any sequela. Among those mentioned above, diarrhea in 2 cases and elevated GOT and GPT in 2 were observed, all of which were transitory and not serious. The blood level of CTRX at 1/2, 1, 2, 4, 6 and 8 hours after intravenous injection with 20 mg/kg to a girl of 8 years and 8 months of age with urinary tract infection was 114, 86, 70, 42, 29 and 21.8 micrograms/ml, respectively. The half-life time was 3.5 hours while the urinary recovery rate up to 6 hours was 58.0%. The concentration in the cerebrospinal fluid of 1 case with H. influenzae meningitis ranged from 2.1 to 8.2 micrograms/ml at 3 hours after administration and from 1.15 to 2.65 micrograms/ml after about 12 hours (prior to the next administration). The above-mentioned results suggest that CTRX is a new antibiotic useful for pediatric infections caused with susceptible bacteria and is effective by intravenous injection with 10 mg/kg twice daily for moderate infections and with 20 mg/kg twice daily for severe ones, except for meningitis. As for purulent meningitis, the administration dosage and frequency will have to be further examined based on the intravenous injection with 50 mg/kg twice daily.

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.

Cefotiam, one of the new cephem antibiotics, was used in 14 cases with pediatric infections: (10 cases with respiratory tract infections, 2 with urinary tract infections, each 1 with purulent meningitis + sepsis and acute appendicitis). The patients were aged between 15 days and 9 years old. The drug was, a rule, given at a daily dose of 50 mg/kg to 100 mg/kg q.i.d. by bolus intravenous injection. The duration of treatment was between 3 and 38 days. The treatment produced the following clinical responses: Out of the 10 cases, good response in 7 with respiratory tract infections, fair in 1 and poor in the remaining 2. The responses in urinary tract infections were excellent in 1 and good in the other case. An apparently clear response was obtained in 1 case with purulent meningitis + sepsis due to K. pneumoniae. Also, an excellent response was seen in 1 case with acute appendicitis. The response rate including fair response was 85.7%. The suspected pathogens isolated from 5 cases (S. aureus: 1. strain, H. influenzae: 1, K. pneumoniae 2, E. coli: 1) were eliminated after CTM administration. Good clinical responses were also obtained in these cases. No side effect was observed. Mild elevation of GOT and GPT was noted during the treatment in 1 case. It is unclear, however, if CTM was associated with this side effect or not. P. aeruginosa, Serratia appeared after superinfection in 1 case.

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.

Experimental and clinical trials were carried out with ceftizoxime in pediatric infections. Results were as follows. 1. The antibacterial activity of ceftizoxime against clinically isolated organisms was determined. Ceftizoxime was more active than cefazolin, cefotiam and cefmetazole against K. pneumoniae, E. coli and H. influenzae. 2. The serum concentrations of ceftizoxime following intravenous injection of 10 mg/kg were 16.2, 10.1, 6.2, 1.8 micrograms/ml at 30, 60, 120, 240 minutes after injection, respectively. Ceftizoxime was excreted with the rate of 97.2% in the 6-hour urine after injection. 3. Twenty-one patients comprising 5 with urinary tract infection, 16 with respiratory tract infection were received ceftizoxime at the doses ranging from 32 to 109 mg/kg divided 3 or 4 times a day. The results were excellent in 8 and good in 13 patients. The rate of satisfactory clinical response was 100%. 4. Slight and transient elevation of GPT was observed in 1 patient. Other side effects were not observed in any of these 21 patients.

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.

Ceftizoxime (CZX) and latamoxef (LMOX), new synthetic cephems, are stable against various types of beta-lactamase and highly active against Gram-negative rods, such as H. influenzae, Serratia, Enterobacter and indole (+) Proteus. In this study, we evaluated clinical effects of CZX and LMOX in the clinical management of infections in acute leukemia. Sixteen episodes of infections were treated with CZX or LMOX. Four causative organisms, P. aeruginosa, S. faecalis, K. pneumoniae and A. faecalis, were identified in 2 episodes of infections. Clinical effects were recognized at 75% in 8 episodes treated with CZX and at 71% in 7 episodes treated with LMOX, respectively. The transient evaluation of GOT, GPT and Al-P, recognized in several cases. In conclusion, the clinical effects of CZX and LMOX are promised in clinical management of infections in acute leukemia.

T-1982 (cefbuperazone), a new cephamycin antibiotic, was basically and clinically studied in the field of pediatrics, and the following results were obtained. 1. The antibacterial activity of T-1982 was compared with that of CEZ, CMZ and ABPC. T-1982 was more active than the other drugs against Gram-negative bacteria, the sensitivity of E. coli (22 strains), K. pneumoniae (18 strains), P. mirabilis (19 strains), P. vulgaris (4 strains), P. morganii (5 strains) and K. oxytoca (4 strains) distributing less than 0.39, 0.1, 1.56, 0.39, 6.25 and 0.2 microgram/ml, respectively. Two of 3 strains of C. freundii were inhibited by 12.5 micrograms/ml. Against Gram-positive bacteria, the activity of T-1982 was inferior to that of the other drugs. S. pyogenes (28 strains) were inhibited by 0.78 microgram/ml or less, but the sensitivity of S. aureus (34 strains distributed 12.5-100 micrograms/ml). 2. T-1982 was administered to each 3 children at a dose of 20 mg/kg by one shot intravenous injection or 1 hour drip infusion, or at dose of 40 mg/kg by 1 hour drip infusion. The mean serum levels at 0.25, 0.5, 1, 2, 4 and 6 hours after one shot intravenous injection of 20 mg/kg were respectively 74.3, 56.3, 42.3, 17.6, 5.7 and 1.2 micrograms/ml with the mean half-life of 1.01 hours. The values were 32.9, 50.0, 73.7, 27.5, 12.4 and 4.5 micrograms/ml and 1.31 hours by intravenous drip infusion of 20 mg/kg and 50.4, 104.7, 136.3, 62.3, 18.6 and 6.9 micrograms/ml and 1.16 hours by intravenous drip infusion of 40 mg/kg. The mean urinary recovery rates within 6 hours were 47.7, 67.6 and 60.9%, respectively. 3. Treatment with T-1982 was made in 28 cases of pediatric infections; 1 case of acute bronchitis, 19 cases of acute bronchopneumonia or lobar pneumonia, 2 cases of acute purulent cervical lymphadenitis, 4 cases of acute pyelonephritis and each 1 case of subcutaneous abscess and suspected bacterial endocarditis. The clinical responses assessed in 27 cases were excellent in 21 cases, good in 5 cases and poor in 1 case, the efficacy rate being 96.3%. Bacteriologically, 2 strains of S. aureus, 3 strains of S. pneumoniae, 4 strains of H. influenzae, 2 strains of E. coli and 1 strain of P. mirabilis were eradicated. One strain of S. faecalis was reduced. No side effects were observed in any cases. Slight elevation of GOT and GPT and that of GOT were noted in each 1 case.
