Pharmacokinetic and clinical studies on sulbactam/ampicillin (SBT/ABPC) were carried out in the field of pediatrics. 1. Absorption and excretion Serum levels and urinary excretion of SBT/ABPC were studied in 4 children with ages 6 to 8 years. The mean serum concentration of SBT at 15 minutes following a single intravenous injection of 30 mg/kg of SBT/ABPC was 27.4 +/- 2.2 micrograms/ml and that of ABPC was 42.8 +/- 3.9 micrograms/ml, and their concentrations declined with mean half-lives of 1.06 +/- 0.15 hours and 0.84 +/- 0.05 hour, respectively, and at 6 hours were 0.3 +/- 0.2 microgram/ml and 0.2 +/- 0.1 microgram/ml on the average, respectively. The urinary recovery rates of SBT and ABPC at 6 hours after the injection were 59.0 +/- 22.4% and 58.4 +/- 25.3% on the average, respectively. 2. Clinical study SBT/ABPC was used for the treatment of a total of 36 pediatric patients with ages ranging 2 months to 11 years and it's clinical effectiveness, bacteriological efficacy and adverse effects were evaluated. Clinical efficacies in 5 patients with acute purulent tonsillitis, 26 with acute pneumonia and 1 with acute pyelonephritis were judged to be excellent in 27 cases and good in 5 cases with an overall efficacy ratio of 100.0%. Clinical efficacies in 6 patients whose infections were caused by beta-lactamase producing strains were judged to be excellent in all cases. Bacteriological efficacies of SBT/ABPC were assessed on 1 strain of Staphylococcus aureus (beta-lactamase producing strain), 2 strains of Streptococcus pneumoniae, 16 strains of Haemophilus influenzae (5 beta-lactamase producing strains and 11 non-beta-lactamase producing strains), 1 non-beta-lactamase strain of Haemophilus parainfluenzae and 2 strains of Escherichia coli (non-beta-lactamase producing strains). All strains except 1 strain of H. influenzae (beta-lactamase producing strain) which decreased in number were eradicated with a bacteriological eradication rate of 95.5%. Only 1 patient complained of diarrhea which was suspected to be related to the drug. No other side effect was reported. Elevations of GOT and GPT were observed in only 1 patient. The above results suggested that SBT/ABPC was a useful drug with preferable safety profile in the treatment for pediatric patients with infectious disease caused by beta-lactamase producing strains as well as those by non-beta-lactamase producing strains.

The therapeutic activity of FCE 22891 was compared with that of two new oral cephalosporins, cefuroxime axetil and cefixime against Streptococcus pneumoniae respiratory infection and subcutaneous abscesses induced by mixed aerobes and anaerobes in mice. In experimental pneumonia FCE 22891 was the most active antibiotic. In aerobic abscesses FCE 22891 proved the most active agent in infections induced by methicillin susceptible and resistant Staphylococcus aureus while all three compounds were very active, against Str. pyogenes. In abscesses caused by Gram-negative bacteria, FCE 22891 showed good and constant efficacy. Cefixime was the most active drug against the two susceptible strains of Escherichia coli and Enterobacter cloacae and also against resistant Esch. coli but was inactive against a strain of Ent. cloacae that produced cephalosporinase. Cefuroxime axetil was less active than the other two drugs against Gram-negative bacteria with adequate efficacy only against a susceptible strain of Ent. cloacae. FCE 22891 was more effective than cefixime and cefuroxime axetil in preventing and reducing the size of abscesses induced by Bacteroides fragilis 101. We conclude that FCE 22891, despite its short half life of 6 min in mice, exerts comparable and sometimes better activity than the two oral cephalosporins characterized by longer half lives.

Clinical trials were carried out on the use of sulbactam/ampicillin (SBT/ABPC) (combination rate of 1:2) in pediatric infections. Results were as follows: 1. The mean half-lives of SBT and ABPC in the serum following intravenous injection of SBT/ABPC were about 1.05 and 0.90 hours, respectively. 2. The mean urinary excretions of SBT and ABPC in 6 hours after intravenous injection of SBT/ABPC were 71.2% and 62.2%, respectively. 3. SBT/ABPC was administered to 23 pediatric patients with various infections: 17 patients with pneumonia, 3 with tonsillitis, 2 with urinary tract infection and 1 with cervical lymphadenitis. The overall efficacy rate was 95.7%. In particular, 2 urinary tract infections caused by highly beta-lactamase producing Escherichia coli were improved by the treatment with SBT/ABPC. 4. No adverse reactions were observed except 2 cases of mild diarrhea. Abnormal laboratory test values included thrombocytosis in 4 and slight elevation of GOT and GPT in 1, but they were transient.

Laboratory and clinical studies of sulbactam/ampicillin (SBT/ABPC) in children have been carried out, and the following results were obtained. 1. Antibacterial effect MICs of SBT/ABPC were only one-tube less than or similar to those of ABPC against susceptible organisms. Against ABPC-resistant organisms at the inoculum size of 10(8) cells/ml however, SBT/ABPC was superior to ABPC when evaluated in terms of their MIC values. When MICs of SBT/ABPC were compared to those of ABPC against organisms with high beta-lactamase producing activities, it was found that many of ABPC-resistant organisms were much susceptible to SBT/ABPC. 2. Absorption and urinary excretion In 2 cases to which 50 mg/kg and 20 mg/kg SBT/ABPC were respectively given over 30 minutes by drip infusion, peak serum levels were obtained at the end of the drip infusion with peak levels of SBT of 45.5 micrograms/ml, 12.5 micrograms/ml, respectively and those of ABPC of 83.0 micrograms/ml, 22.9 micrograms/ml, respectively. The half-lives of SBT and ABPC were 0.94 hour and 0.98 hour, respectively. The mean urinary excretion rates in the first 6 hours after the end of administration were 84.4% for SBT and 63.1% for ABPC. 3. Clinical results Clinical efficacies were evaluated in 24 cases including 9 cases of pneumonia, 2 cases of upper respiratory infection, 7 cases of urinary tract infection and 1 case each of bronchopneumonia, pyothorax, tonsillitis, streptococcal infection, ++ phlegmon and staphylococcal scalded skin syndrome. Clinical efficacies were excellent or good in 19 cases with an overall efficacy rate of 86.4%. Adverse effect was found in 1 case with nausea and vomiting, and abnormal laboratory test values observed were 2 cases each of eosinophilia, slight elevation of GOT and GPT and elevation of LDH, but they were not serious.

The usefulness of sulbactam/ampicillin (SBT/ABPC) in the treatment of pediatric infections was evaluated. 1. Twenty pediatric patients with infection were treated with SBT/ABPC and an intravenous dosage of 27.8-47.4 mg/kg, 3 to 4 times a day. Clinical efficacies in 18 patients excluding 2 patients of Mycoplasma pneumonia (9 cases of pneumonia, 6 urinary tract infection, 1 tonsillitis, 1 maxillary sinusitis and 1 osteomyelitis) were judged to be excellent in 13 patients and good in 5. There was no case of failure. 2. Bacteriological efficacies against 16 strains (1 Staphylococcus aureus, 3 Enterococcus faecalis, 4 Haemophilus influenzae, 2 Haemophilus parainfluenzae, 5 Escherichia coli and 1 Serratia sp.) isolated from 13 of the 18 patients were rated as "eradicated" for 13 strains, "decreased" for 1 and "unchanged" for 2 with an eradication rate of 81.3%. Of 13 strains eradicated, 3 were those with high beta-lactamase productivity. 3. Rash as a side effect developed in 1 patient and eosinophilia and elevated GOT and GPT were observed in 7 patients but none of them were serious. 4. Blood levels of the drug following an intravenous dose of 30 mg/kg were determined in 2 pediatric patients. Blood levels of SBT and ABPC at 30 minutes after intravenous administration were 19.0 and 29.2 micrograms/ml in one patient and 21.0 and 31.6 micrograms/ml in another, respectively, and those at 4 hours were 0.48 and 0.62 microgram/ml in one patient and 0.59 and 0.89 microgram/ml in another, respectively. The half-lives of SBT were 0.67 and 0.70 hour and those of ABPC were 0.64 and 0.69 hour in the 2 patients, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

Twenty-nine intubated pediatric patients were prospectively studied to determine whether nontypable Haemophilus influenzae (NTHI) is associated with the development of nosocomial pneumonia. Throat cultures and tracheal Gram stains, leukocyte counts and cultures were obtained immediately following intubation, then serial studies on tracheal secretions were performed. Median patient age was 13 months. One patient had preexisting lung disease and 14 (48%) had pneumonia when intubated. There were five deaths. NTHI was recovered from the initial throat or tracheal culture in seven patients (24%); none developed a nosocomial lower respiratory tract infection. NTHI was not associated with any of three cases of nosocomial pneumonia. Three of 12 NTHI isolates were beta-lactamase producers. Tracheal leukocyte counts and Gram stains were not predictive of pneumonia, either at the time of intubation or subsequently. We conclude that NTHI in the oropharynx or trachea is not predictive of pneumonia among intubated pediatric patients.

1. Absorption and elimination Serum and urinary levels of cefodizime (CDZM, THR-221) were determined in 7 children with ages ranging from 3 to 12 years after a intravenous bolus injection of the drug at 20 mg/kg. The average serum level of the drug was 119.27 +/- 13.83 micrograms/ml at 30 minutes, then decreased gradually with a half-life of 2.01 +/- 0.25 hours to 10.56 +/- 2.93 micrograms/ml at 6 hours. The average urinary elimination rate was 77.34 +/- 12.60%. 2. Clinical study CDZM was given to the following 39 patients with ages ranging from 2 months to 15 years and clinical efficacy, bacteriological response and adverse reactions were evaluated. The treated cases were 2 cases of acute purulent tonsillitis, 30 cases of acute pneumonia, 1 case of acute purulent otitis media and 2 cases of acute urinary tract infections. Clinical efficacies were excellent in 29 cases, good in 5 cases and poor in 1 with an efficacy rate of 97.1%. Organisms presumed to be pathogens included 3 strains of Streptococcus pneumoniae, 1 beta-Streptococcus, 1 Staphylococcus epidermidis, 9 Haemophilus influenzae (1 beta-lactamase producing strain and 8 non-producing strains) and 1 Enterococcus faecalis. The last one was decreased and the others were eradicated with an eradication rate of 93.3% for all strains. Adverse reactions occurred in no patients. Abnormal changes in laboratory test values involved only 1 case each of elevated GOT, elevated GOT and GPT, eosinophilia and thrombocytosis. Based on the above-mentioned result and features of this drug, it was confirmed that this drug showed an excellent usefulness in the treatment of infections in childhood. It may be also effective in the management of infections under immunosuppression.

Eighteen patients 2 months to 11 years of age with culture proven bacterial infections were treated with parenteral ticarcillin/clavulanic acid in a noncomparative study. Seven patients had pneumonia, two had tracheobronchitis, three had soft tissue abscess, two had periorbital cellulitis, three had urinary tract infection and one had purulent bursitis. Four of the 18 were bacteremic. Organisms treated included Staphylococcus aureus (6), Pseudomonas aeruginosa (5), Haemophilus influenzae (2), Branhamella catarrhalis (2), Escherichia coli (1), Streptococcus pneumoniae (1), Klebsiella pneumoniae (1), Streptococcus pyogenes (1) and Serratia marcescens (1). Thirteen of 15 (87%) organisms tested were beta-lactamase positive. Therapy was given intravenously in six doses per day at 310 mg/kg. Duration of treatment ranged from 5 to 28 (mean 11) days, with an average time of 4 days to clinical improvement. Seventeen patients (94%) were clinically cured. One patient with recurrent aspiration pneumonia due to mixed infection with multiple gram-negative enteric bacilli failed therapy. Adverse effects were minimal and transient. Notably, mild to moderate thrombocytosis occurred in four (22%) patients that resolved uneventfully. We conclude that ticarcillin/clavulanic acid is safe and effective therapy for serious infections in hospitalized children.

Pharmacokinetic, bacteriological and clinical studies on cefpodoxime proxetil (CPDX-PR, CS-807), a newly developed oral cephem, were carried out in the treatment of infectious diseases in the field of pediatrics. 1. Since CPDX demonstrates very powerful antimicrobial actions against such Gram-negative bacilli as Escherichia coli, Salmonella sp., Klebsiella pneumoniae and Serratia sp., such Gram-positive cocci as Streptococcus pyogenes and Streptococcus pneumoniae, and beta-lactamase producing Branhamella catarrhalis and Haemophilus influenzae, this drug was thought to be useful for the treatment of pediatric infectious diseases when main causative bacteria in the field of pediatrics were taken into account. 2. When changes in blood and urine concentrations of CPDX following the administration of this drug at 3.7 mg/kg before meal were determined, Cmax and T1/2 were found to be 2.98 micrograms/ml at 2-hour and 1.73 hours, respectively; an urinary excretion rate in the first 6 hours and a maximum urine concentration were 32.5% and 52 micrograms/ml, respectively. 3. Clinically, 8 of 8 patients with the upper respiratory tract infections (100%), 28 of 29 patients with bronchitis and/or pneumonia (96.6%), 3 of 4 patients with otitis media (75%), 2 of 2 patients with sinusitis (100%), 3 of 3 patients with the skin soft tissue infections (100%), 1 of 1 patient with bacterial enteritis (100%) and 11 of 14 patients with urinary tract infections (78.6%) responded well to the treatment with CPDX-PR, showing a 91.8% efficacy rate in all the patients treated. 4. Bacteriologically, Staphylococcus aureus, Staphylococcus epidermidis, S. pyogenes, S. pneumoniae, E. faecalis, B. catarrhalis, H. influenzae, E. coli and Salmonella typhimurium were all eradicated from 5, 1, 4, 6, 1, 5, 5, 11 and 1 patient, respectively. An eradication rate in all the patients examined was 97.5% (39/40). 5. Gastrointestinal symptoms appeared as side effects in 2 of 71 patients (vomiting in 1 and diarrhea in 1), hence, an incidence of side effects was 2.8% (2/71). As for abnormal laboratory findings, eosinophilia, thrombocytosis and increases in GOT and GPT were observed in 3 of 39 patients examined (7.7%), 1 of 39 patients (2.6%) and 2 of 34 patients (5.9%), respectively. In addition, we also examined the effect of the drug on the hemostatic system, but found no changes upon the treatment. Based on these results, it appeared that CPDX-PR was a useful and safe drug in treatment of infectious diseases in the field of pediatrics when administered 2-3 times a day at a dose of 3-6 mg/kg.

Infectious episodes in 90 patients with hematological disorders were treated with sulbactam/cefoperazone (SBT/CPZ), a new combination drug of a potent beta-lactamase inhibitor, sodium sulbactam, and a third generation cephalosporin, sodium cefoperazone. Clinical responses to the SBT/CPZ regimen were excellent in 23 cases, good in 30 cases, fair in 11 cases, and poor in 26 cases. The overall efficacy rate (percentage of cases showing excellent or good responses) was 58.9%. Efficacy rates classified according to different infections were: 80% in documented sepsis, 57.6% in suspected sepsis, 61.1% in pneumonia and 50% in other infections. One episode of side effect was encountered with redness and itching of skin. Hepatic disorders were observed in 3 cases. These adverse reactions, however, were not serious. These results indicate that SBT/CPZ has a high therapeutic efficacy to severe infections in patients with hematological disorders.
