Cefodizime (THR-221, CDZM), a newly developed injectable cephem antibiotic, was injected intravenously to 13 cases of pediatric infections. Patients received the drug at a dose level of approximately 20 mg/kg x 3 times daily. The results obtained are summarized as follows. 1. Clinical efficacy was excellent in 4 patients, good in 6 and poor in 0 for 10 cases (2 phlegmon, 1 periproctal abscess, 5 pneumonia and 2 bronchitis) except 3 Mycoplasma pneumonia. 2. Three strains of pathogens were followed for their changes (Streptococcus pyogenes in 1 phlegmon, Klebsiella pneumoniae in periproctal abscess and Haemophilus influenzae in 1 bronchitis) and they were found to have been eliminated. 3. No adverse reactions occurred. Abnormal changes in laboratory test data found were 2 cases of eosinophilia, 1 cash each of increased GOT and GPT, and thrombocytosis, but none of them was severe.

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.

A newly developed cephalosporin, cefteram pivoxil (CFTM-PI, T-2588), was evaluated clinically in 40 patients. A pharmacokinetic study was also performed with 8 patients. CFTM-PI was administered as granules. One patient was given CFTM-PI at a dose of 1.5 mg/kg, each of 3 patients was given the drug at a dose of 3 mg/kg and each of 4 patients at a dose of 6 mg/kg. In most cases, serum concentrations of CFTM were determined at 2, 3, 4, and 6 hours after dosing. Urinary concentrations of CFTM were measured for urinary samples collected during periods of 0-2, 2-4, 4-6 and 6-8 hours after dosing. CFTM was assayed using the disk or the cup method using Klebsiella pneumoniae ATCC 10031 as the test organism. The clinical evaluation was conducted in 40 children including 13 patients of acute tonsillitis, 10 of acute lacunar tonsillitis, 10 of scarlet fever, 2 of acute bronchitis, 2 of pneumonia, and 1 each of pneumonia with enteritis, phlegmon and urinary tract infection. The patients were from 4 months to 13 years old. Daily doses were from 8.7 to 12 mg/kg. After CFTM-PI administration in doses 1.5 mg/kg, 3 mg/kg and 6 mg/kg, peak serum concentrations of CFTM were 0.38 microgram/ml, 0.73-2.25 micrograms/ml and 1.2-2.9 micrograms/ml, respectively, and half-lives were 1.55, 0.95-2.30 and 0.80-2.72 hours, respectively. Urinary excretion rates up to 6 or 8 hours after dosing were 10.8-24.7%. Clinical efficacies of CFTM-PI in 40 patients were "excellent" in 27 children, "good" in 12 children and "fair" in 1 with an efficacy rate of 97.5%. Twenty seven strains of causative organisms, including 15 strains of Streptococcus pyogenes, 1 of Escherichia coli, 1 of Salmonella 04, 6 of Haemophilus influenzae, 1 of Haemophilus parainfluenzae and 3 of Branhamella catarrhalis, were isolated. After treatment all strains except 1 strain of B. catarrhalis (unchanged), Salmonella 04 (unknown) and 1 strain of H. parainfluenzae (unknown) were eradicated. Side effects observed clinically were only 1 case of diarrhea. Eosinophilia was observed in 1 case.

Pharmacokinetic and clinical studies of ceftizoxime (CZX) were performed in infants given intravenously. The obtained results are summarized as follows. 1. Serum concentrations of CZX in 2 and 3 day-old mature infants given 20 mg/kg by one shot intravenous injection peaked at 49.0 and 57.9 micrograms/ml in 1 hour and decreased to 14.4 and 24.9 micrograms/ml in 8 hours after dosing, respectively. Half-lives were 3.9 and 5.6 hours, respectively. In 5 day-old or older mature infants, peak serum levels ranged from 20.9 to 38.0 micrograms/ml at 1 hour after the injection. Levels of CZX at 8 hours after injection were 1.31 to 7.32 micrograms/ml. Half-lives were 1.6-3.0 hours in all the infants except one. 2. In a 3 day-old premature infant given the same dose by a bolus intravenous injection, the serum level peaked at 45.7 micrograms/ml in 1 hour after the injection. The level at 8 hours after injection was 15.7 micrograms/ml. The half-life was 4.2 hours. In 5-15 day-old premature infants, half-lives were 2.3-3.1 hours in all the infants except one. 3. Serum concentrations of CZX in 1 and 2 day-old infants given 20 mg/kg by intravenous drip infusion peaked at 49.4 to 115.0 micrograms/ml in 1 hour after dosing. Half-lives were rather long, 4.0 and 5.1 hours, in the 2 infants. 4. Peak serum levels and half-lives tended to be lower and shorter in 5 day-old or older ones than in the 3 day-old or younger infants. 5. No changes in the serum concentration were observed even after dosing with 20 mg/kg of continuous one shot intravenous injection. 6. Urinary recovery rates during the first 8 hours (one is 6 hours, two is 9 hours) after 20 mg/kg intravenous bolus injection of CZX tended to be lower in 3 day-old or younger infants than in 5 day-old or older infants. 7. Eleven infants with various bacterial infections were given CZX by intravenous bolus injection or drip infusion. Dosage of CZX used in the present study were 36-148 mg/kg/day in 2-3 divided doses. Duration of treatment ranged from 3 to 12 days. Clinical efficacy of CZX was excellent or good in all the infants with acute bronchitis, acute pneumonia, suspected sepsis infected in uterine, acute otitis media, cellulitis, meningitis caused by Klebsiella pneumoniae and Escherichia coli, acute urinary tract infection and periproctic abscess except 1 case of acute bronchitis.(ABSTRACT TRUNCATED AT 250 WORDS)

The investigations the frequency of the occurrences of hospital infections were carried in a General Pediatric Ward. Most of the infections (77 per cent) appeared in children up to one year of age. The hospital infections mostly affected children residing in rural areas. The etiological agent was E. coli (36 per cent), Proteus (22.7 per cent) Klebsiella and Staphylococcus. The infections caused by E. coli mainly appeared in girls, others- in boys. The frequency of the occurrences of hospital infections was also analysed with respect to the primary disease of a child. In most cases of additional infections were found in children with upper respiratory tract infections, pneumonia and bronchitis. The above differences are statistically valid.

Fundamental and clinical studies on cefuzonam (L-105, CZON), a newly semisynthesized cephem antibiotic, were carried out in the field of pediatrics and the following results were obtained. Antibacterial activities of CZON against clinically isolated strains of Staphylococcus aureus, S. epidermidis, Streptococcus pneumoniae, S. pyogenes, Escherichia coli, Klebsiella pneumoniae, Haemophilus parainfluenzae and H. influenzae were compared with those of cefmenoxime (CMX), latamoxef (LMOX), cefoperazone (CPZ), cefmetazole (CMZ), cefotiam (CTM) and cefazolin (CEZ). CZON was nearly as active as CEZ against S. aureus and S. epidermidis and superior to other antibiotics against other Gram-positive cocci. Against Gram-negative rods, CZON was as active as CMX and superior to other 5 antibiotics compared. Serum concentrations and urinary excretion rates after intravenous bolus injection of CZON at doses of 10 mg/kg, 20 mg/kg and 40 mg/kg for 5 minutes in 1, 5 and 4 cases, respectively, were determined. Mean serum concentrations of CZON at these dose levels were 11.0, 43.8 and 111.5 micrograms/ml at 15 minutes, 2.4, 10.3 and 30.3 micrograms/ml at 1 hour and 0.17, 0.72 and 1.28 micrograms/ml at 4 hours, with serum half-lives of 1.79, 0.88 and 1.19 hours, respectively. Mean cumulative urinary excretion rates within 6 hours after administration were 47.9, 56.3 and 40.3%, respectively. Thirty-four pediatric patients with various bacterial infections (tonsillitis 2, acute bronchitis 1, pneumonia 14, pyothorax 1, sepsis 1, suppurative lymphadenitis 1, UTI 13 and enteritis 1) were treated with CZON at a daily dose of 40-94 mg/kg t.i.d. or q.i.d.. The overall clinical efficacy rate was 94.1%. No adverse reactions were observed except 2 cases with mild diarrhea. Abnormal laboratory findings were also mild; slight elevation of GOT and GPT in 2, eosinophilia in 1 and thrombocytosis in 1. These results clearly indicate the usefulness of CZON in the treatment of bacterial infections in children.

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.

The most important lower respiratory infection is pneumonia, the fourth leading cause of death. Most cases of bronchitis are of viral etiology and are not major problems. Empyema can present an important problem in management. Although the diagnosis of pneumonia is usually relatively straightforward, the specific etiologic diagnosis remains a major problem. Availability of empyema fluid or a positive blood culture result can be helpful in making the etiologic diagnosis, but these are unavailable in most patients. Screening of sputum Gram stains under 100 X magnification is very important; there should be fewer than 10 squamous epithelial cells, more than 25 polymorphonuclear leukocytes, or both per field of this size. The major causes of pneumonia are Streptococcus pneumoniae, Mycoplasma pneumoniae, anaerobic bacteria, Staphylococcus aureus, various gram-negative aerobic or facultative bacilli and Legionella. However, many other organisms are capable of causing pneumonia, even in the immunocompetent host. Further adding to the problem is the fact that a number of different organisms are manifesting increasing resistance to antimicrobial agents. Our study with ticarcillin plus clavulanic acid included seven patients with pneumonia, one with empyema, and one with purulent tracheobronchitis. Organisms recovered from pleural fluid, transtracheal aspiration and sputum or tracheostomy aspirate included multiple anaerobes, pneumococci, S. aureus, Hemophilus influenzae, Klebsiella pneumoniae, K. ozaenae, Pseudomonas aeruginosa, Acinetobacter, Enterobacter cloacae, Proteus mirabilis, beta-hemolytic streptococci, Neisseria meningitidis and Branhamella catarrhalis. Several of the organisms were ticarcillin resistant. Eight of the patients had cures and the other patient showed improvement. Only minor side-effects were encountered--Coombs' positivity (without hemolysis), eosinophilia, drug fever and one case of questionable neutropenia.

Sulbactam/cefoperazone (SBT/CPZ) was used in pediatric patients with acute infections, and the following results were obtained. SBT/CPZ was administered to 18 pediatric patients with acute infections. Out of them, 14 patients, i.e., 3 with acute tonsillitis, 1 with acute laryngitis, 1 with acute bronchitis, 4 with acute pneumonia, 4 with bronchopneumonia, 1 with pyothorax, were adopted for the evaluation, and the other 4 were excluded because they were judged inadequate for clinical efficacy evaluation. The clinical efficacy of SBT/CPZ was assessed as excellent in 4, good in 9 and fair in 1. The effective rate was 92.9%. In 6 cases causative organisms were detected, i.e., Haemophilus influenzae in 3, Klebsiella in 1 and Staphylococcus aureus in 2 cases. Eradication of these organisms was confirmed in all cases except for 1 patient with pyothorax caused by S. aureus. The doses used in 12 out of the evaluated 14 cases ranged from 58.4 to 80 mg/kg/day, 84.1 mg/kg/day was used in 1 case and 101.4 mg/kg/day was used in 1 case with pyothorax. Patients with severe infections were generally given large doses. The frequency of administration was 3 times per day except 1 case, and intravenous drip infusion was used in all cases. The duration of treatment was 2- less than 3 days for 7 cases, 3-5 days for 6 cases and 9 days for 1 case (pyothorax). No clinical side effects were observed in any case. In laboratory examinations, a slight elevation of GOT was observed in 1 case, but no abnormal findings in the other cases. From the above results, SBT/CPZ was considered to be a highly useful drug in the treatment of pediatric infections.
