This report summarizes the results of joint studies in pediatrics on aztreonam, the first monobactam antibiotic for practical use. Pharmacokinetics was studied in 53 cases administered with 10, 20, 40 and 50 mg/kg of aztreonam (AZT) by intravenous injection and 20 cases with 10, 20, 30, and 40 mg/kg by drip infusion. All the cases had normal hepatic and renal functions at the administration. T1/2 was in a relatively fixed range of 1.35-1.56 hours in intravenous injection cases and 1.30-1.55 hours in drip infusion. One hour after commencing administration of standard 20 mg/kg, the serum concentrations were 50.18 +/- 4.24 micrograms/ml in intravenous injection and 116.33 +/- 10.18 micrograms/ml in drip infusion and even 6 hours after the end of the administration, they were 5.80 +/- 1.16 micrograms/ml and 3.38 +/- 0.58 micrograms/ml, respectively. The cerebrospinal fluid penetration was studied on suppurative meningitis (5 cases) and nonbacterial meningitis (3 cases). The penetration was generally good with sufficient concentration for meningitis caused by E. coli and H. influenzae. Amount of the penetration decreased as the cases were improved. Twenty-nine (29) cases were excluded and 262 cases of total 291 were clinically assessed, and the pathogen-isolated 167 cases of 262 were principally analyzed. Efficacy of AZT was "excellent" for all 3 cases of E. coli sepsis and 1 case of N. meningitidis meningitis and "good" for 1 case of H. influenzae meningitis. The effective rate was 94.6% for 37 pneumonia cases, 94.7% for 76 UTI cases and 88.5% on the whole including as many as 98 "excellent" cases. However, the effective rate for 21 enteritis cases was only 52.4%. Similar trend was observed in the pathogen-unknown group and overall effective rate of total 267 cases was 86.8%. The clinical effect by pathogen was 97.7% for 44 E. coli cases and 97.1% for 34 H. influenzae cases, showing excellent results for the GNB group. AZT was also effective for 8 out of 11 P. aeruginosa cases. With regard to microbiological effect by pathogen, AZT showed a high rate of bacterial elimination for GNB, primarily 98.1% for E. coli and 100% for H. influenzae followed by 76.9% for P. aeruginosa. However, it was only 30.0% for Salmonella. Excluding the Salmonella cases, GNB elimination rate was 93.5%. Clinical and microbiological dose response was not clear partly because, same as the previous studies, the effective rate of AZT was high. It was considered, however, standard dose of 20 mg/kg X 3 approximately 4 times a day was recommendable.(ABSTRACT TRUNCATED AT 400 WORDS)

Cefotaxime (CTX) was administered to 117 pediatric patients. Although 26 of these patients were excluded from the clinical evaluation of the study because other antimicrobial agents were given concomitantly with CTX or because no infectious diseases were proved, these cases were evaluated for adverse effects of the drug. The remaining 91 cases were evaluated for clinical effect; pneumonia in 56 cases, septicemia in 5, suspected septicemia in 5, meningitis (aseptic cases included) in 3, urinary tract infection in 5 and other diseases in 17. No pathogenic organisms were identified in any of the pneumonia cases, even either by bacterial culture or other laboratory test methods. Pathogens of septicemia were E. coli in 3 cases, K. pneumoniae in 1 and E. agglomerans in 1. Those of urinary tract infections were E. coli in 3 cases, a mixed infection of S. aureus and an unidentified species of Gram-negative rods in 1, and unknown in 1. Clinical effectiveness rates of CTX were 78.6% in pneumonia and 100% in septicemia, suspected septicemia and urinary tract infections. One patient with purulent meningitis caused by H. influenzae was also treated with CTX successfully. Adverse reactions and abnormal laboratory findings were observed in 12 cases (12/117 = 10.3%); rash in 2 cases, vomiting in 1, abdominal pain in 1, diarrhea in 5, granulocytopenia and thrombocytopenia in 1, eosinophilia in 3 and elevation of liver enzymes (GOT and LDH) in 1.

Aspoxicillin (ASPC) was evaluated for its efficacy and safety in 30 infants and children with acute bacterial infections. The disease categories included acute respiratory tract (22), soft tissue (3), urinary tract (3) infections, sepsis with pyothorax (1) and purulent meningitis (1). ASPC was effective in all but 1 case of pneumonia due to beta-lactamase-positive H. influenzae (effective rate; 96.7%). Adverse reactions and abnormalities of the laboratory tests were not associated with the ASPC therapy in any of the cases. The serum half-life of ASPC after an intravenous bolus injection was 0.883 +/- 0.194 hour and excretion into urine was rapid. From the present results, ASPC is a safe and effective antibiotic when used in patients with susceptible bacterial infections.

Clinical application to ascertain the effects of aspoxicillin (ASPC), a new semisynthetic penicillin antibiotic, upon several infectious diseases of children was performed in 7 cases with pneumonia, 5 cases with acute bronchitis, each case with tonsillitis, enterocolitis, urinary tract infection and suspected sepsis. ASPC was injected by drip infusion and the dosage was 63-117 mg/kg/day in 3 and 4 times a day. Clinical efficacy obtained as "excellent" was in 7 cases, "good" in 8 cases "poor" in 1 case, and efficacy rate was 93.8%. From the bacteriological point of view, eliminated in each of H. influenzae, H. parainfluenzae, group A beta-Streptococcus and unchanged in a case of E. coli. There were transient thrombocytopenia in 2 cases and eosinophilia in 3 cases.

Clinical usage of aztreonam (AZT), a newly synthesized antibiotic which belongs to monobactam, was evaluated for its efficacy and safety in 22 patients aged from 1 month-old to 13 year-5 month-old with bacterial infections and the following results were obtained. AZT was administered to 4 patients with pyelonephritis and 10 patients with tonsillitis at a daily dosage of 40.4-120.9 mg/kg and to 5 patients with clinical sepsis associated with agranulocytosis caused by intensive antileukemic therapy at a daily dosage of 142.4-171.4 mg/kg, divided into 3 or 4, by intravenous injection or by 30 minutes drip infusion. The clinical results of these 19 evaluable patients were as follows: excellent; 10 cases, good; 5 cases, fair; 2 cases, poor; 2 cases. The over all efficacy rate was 78.9% and that of pyelonephritis and tonsillitis was 100.0%. No clinical side effects were observed in any 23 patients, including a patient who proved to be suffering from Mycoplasma pneumoniae infection, and no abnormal laboratory findings caused by AZT was noticed. The MICs of AZT against 9 strains isolated from patients with pyelonephritis and those with tonsillitis were as follows: MICs against all of 3 strains of K. pneumoniae were less than 0.05 microgram/ml. MICs against 2 out of 4 strains of H. influenzae were less than 0.05 microgram/ml and those of the remaining 2 strains were 0.10 microgram/ml. MIC against 1 strain of S. aureus was 1.56 microgram/ml. MIC against 1 strain of S. epidermidis was more than 100 micrograms/ml.(ABSTRACT TRUNCATED AT 250 WORDS)

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)

Samples of CSF, serum, and urine from 162 children with a clinical diagnosis of possible bacterial infection were examined by CIE within 1 hr of admission to the hospital. Results obtained were compared to information derived from gram stain and bacterial cultures of these specimens. Thirty-eight of 59 patients with culturally proved bacterial infections had positive CIE determinations at the time of admission. Highest correlation between culture and CIE results was in patients with meningitis due to Hemophilus influenzae type b while poorest correlation was obtained in children with pneumococcal septicemia. PRP within serum or CSF was quantitated on 21 occasions in patients with H. influenzae meningitis. Patients who experienced sequelae of their meningitis had significantly (p less than 0.005-0.025) higher levels of PRP within CSF and serum than those whose recovery was uneventful.

Anti-type b antibodies were detected in newborns and in most 6- to 8-week-old rabbits, similar to those observed in humans. Culture of the pharynx and rectum of rabbits at varied ages failed to yield Haemophilus influenzae type b. Bacteria with cross-reacting antigens were observed in both the pharyngeal and rectal cultures from rabbits of varied ages. Rabbits without preexisting serum anti-type b antibodies were highly susceptible to septicemia and death after injection of small numbers of H. influenzae type b. Passively acquired antibody, whether observed in newborns or injected into animals without preexisting antibodies, conferred a high degree of protection against H. influenzae type b.

To 6 cases of children in 2 groups of 3 each, newly developed sulbactam/cefoperazone (SBT/CPZ) was given at 20 and 40 mg/kg by intravenous bolus injection, respectively, and the serum and urinary concentrations and recoveries of SBT and CPZ were determined. To 1 case of purulent meningitis, this drug was given at 40 mg/kg by intravenous bolus injection, and the cerebrospinal fluid and serum concentrations of SBT and CPZ were determined. Susceptibility tests to SBT/CPZ and CPZ of total 289 strains were conducted; Gram-positive cocci tested consisted of 26 S. aureus strains, 20 S. pyogenes strains and 21 S. pneumoniae strains, and Gram-negative bacilli consisted of 24 H. influenzae strains, 22 E. coli strains, 26 K. pneumoniae strains, 24 E. cloacae strains, 21 E. aerogenes strains, 19 Citrobacter sp. strains, 20 S. marcescens strains, 23 P. mirabilis strains, 23 indole-positive Proteus sp. strains and 20 P. aeruginosa strains. SBT/CPZ was given to total 43 cases at a mean daily dosage of 80.4 mg/kg, in 3 or 4 divided doses (6 cases in 3 and 37 cases in 4), 1 case receiving the drug by drip infusion over 30 minutes (in 3 divided doses) and all the other 42 cases by intravenous bolus injection, for 7 days on an average. They consisted of 2 cases of tonsillitis, 1 case of otitis media, 1 case of otitis media associated with mastoiditis, 30 cases of pneumonia, 1 case of suspected septicemia, 1 case of purulent meningitis, 5 cases of urinary tract infection, 1 case of purulent lymphadenitis and 1 case of submaxillaritis. And the clinical and bacteriological effects were evaluated. Also, side reactions and laboratory examinations for abnormal values due to administration of this drug were made on 47 cases including 4 drop-outs. The following results were obtained: After administration of this drug to 2 groups of 3 children each at 20 and 40 mg/kg by intravenous bolus injection, mean serum concentrations of both SBT and CPZ reached the peaks in 5 minutes; SBT levels were 60.9 and 124.7 micrograms/ml for the 2 groups and CPZ levels were 105.0 and 214.1 micrograms/ml, respectively. In either group, CPZ levels were 1.7 times as high as SBT levels, and there was observed a dose-response in both. In the 20 mg/kg group, mean half-lives of SBT and CPZ were 0.96 and 1.24 hours, respectively, and in the 40 mg/kg group, they were 1.01 and 1.32 hours, CPZ values tending to be longer.(ABSTRACT TRUNCATED AT 400 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.
