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.

Clinical studies were performed on cefodizime (THR-221, CDZM), a new cephem antibiotic as described below. CDZM was administered to 13 patients in dose levels ranging from 55 to 96 mg/kg/day t.i.d. for 3-7 days (5.5 days on average). These patients included 8 with pneumonia, 2 with tonsillitis, 1 each with bronchitis, phlegmon and urinary tract infection. The overall efficacy rate was 92.3%, i.e., efficacy was excellent in 8, good in 4 and poor in 1. Bacteriological efficacy was 83.3%, i.e., 5 strains of bacteria (Streptococcus pneumoniae 1, Haemophilus influenzae 3, Haemophilus parainfluenzae 1) were eradicated and 1 was unchanged (Enterobacter cloacae, MIC greater than 100 micrograms/ml). Clinical side effect was not observed during the treatment. Laboratory abnormalities were observed in 2 cases, i.e., a slight elevation of GPT and a mild eosinophilia. The above results suggest that CDZM is a useful antibiotic for treating pediatric bacterial infections.

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.

The efficacy of ceftazidime in the treatment of neonatal sepsis was studied in 42 low birthweight premature babies. Forty-nine courses of ceftazidime (25 mg/kg bd, iv or im were administered. In 19 babies, treatment was stopped after 48 h, the remainder were treated for 5 days or more. Six neonates had bacteriological evidence of infection, one other was pyrexial and 29 had radiological evidence compatible with respiratory tract infection. Eight of the study population died. Only one death was attributed to infection which arose 3 days after completion of a 5-day course of ceftazidime. Two babies developed clinical signs of necrotizing enterocolitis (NEC). Clostridium difficile (7) and Cl. perfringens (2) were isolated from 34 post-treatment faecal samples but not from the two babies with NEC. No faecal sample contained Cl. difficile toxin. Post-treatment cultures from 12 neonates yielded ceftazidime-resistant micro-organisms. Ceftazidime therapy was not associated with significant alteration in serum alanine aminotransferase, urea, creatinine, protein or albumin. Four babies had an eosinophilia, three transient and one following two intrauterine transfusions. Coombs' tests were performed on 17 babies. There were no false positives. The abnormal clotting studies observed in one baby were not due to ceftazidime. In a concurrent pharmacokinetic study, the half-life of ceftazidime was 7.4 (SD +/- 4.1) h following iv administration. Other pharmacokinetic values were C max 74 (SD +/- 20) mg l-1 trough concentration 20 (SD +/- 10) mg l-1. Total body clearance ranged from 0.13 to 2.10 ml min-1 per kg and increased with increasing postnatal age.(ABSTRACT TRUNCATED AT 250 WORDS)

A pharmacokinetic and clinical study of ceftizoxime (CZX), a newly developed cephem antibiotic intended for parenteral use, was conducted in premature and newborn infants, and resulted in the following findings. 1. Pharmacokinetics (1) Average serum half-lives (T 1/2) following a one shot intravenous dose of 20 mg/kg of CZX to mature and premature newborn infants in age groups of 0-3, 4-7, 8-14, and 15-30 days were: 4.14, 3.01, 2.57, and 1.98 hours (for mature infants) and 5.26, 4.59, 3.71, and 2.64 hours (for premature infants), respectively, decreasing with ages in days of the infants. (2) Average T 1/2's after a one shot 10 mg/kg dose was similar to that after a 20 mg/kg dose. Serum concentrations of CZX were dose-dependent. (3) T 1/2 after 1-hour intravenous drip infusion revealed a same trend after one shot injection. (4) Urinary in the first approximately 6 hours recoveries following a 20 mg/kg one shot dose to mature and premature newborn infants were as follows: 35% (0-3 days old) and 45-55% (4 days old and older) in mature infants and 30% (0-3 days old) and 45% (4 days old and older) in premature infants. 2. Therapeutic effectiveness (1) The subjects examined were 112 newborn infants consisting of 83 with infections and 29 who received CZX for prophylaxis. The 83 infants had 86 cases of infections, which were classified as A, when the causative organisms were identified and as B, when the causative organisms were not identified. Rates of therapeutic effectiveness were 95.0% for group A and 95.7% for group B. Bacteriological effectiveness were studied on 41 strains isolated from group A, and were as high as 89.5% for Gram-positive organisms and 95.5% for Gram-negative organisms. The rate of successful prophylaxis for the 29 infants was 96.6%. (2) Side effects did not occur among the 120 newborn infants. Laboratory tests with abnormalities included leukopenia, neutropenia, eosinophilia, thrombocytosis and increased GOT or GPT. These pharmacodynamic and clinical findings have fully substantiated the satisfactory therapeutic usefulness of CZX in both the treatment and prevention of neonatal infections in the usual dose of 20 mg/kg, which is to be given b.i.d. for infants up to 3 days old; b.i.d. or t.i.d. for infants 4 to 7 days old, and t.i.d. or q.i.d. for infants 8 days old and older. The drug can be given in a daily dose as high as 120 mg/kg when infection is severe.

MK-0787 (Imipenem)/MK-0791 (Cilastatin sodium), a new compound of Thienamycin, was administered in treatment of 35 patients (36 cases) with chronic complicated UTI or for prevention of serious infections with much complicated factors. The patients were principally treated at a daily dose of 1 g for over 10 days. The efficacy rate of 26 patients who were evaluable in the early phase (4-7 days) was 88.5%, while it became up to 92.3% in the final phase judgment. As for clinical usefulness, the result was obtained to be as high as that of the clinical efficacy. In bacteriological study, 35 strains were clinically isolated including 7 strains of P. aeruginosa from UTI. All the strains disappeared with an eradication rate of 100% after treatment. Strains appearing after Imipenem/Cilastatin sodium treatment mainly consisted of fungi. Usefulness judgements tended to be greater in the final phase than in the early phase. As for side effects, vomiting was recorded in one case, in which the administration was discontinued. In laboratory findings there were 3 cases with elevated GPT, 2 cases with elevated GOT, one case with elevated gamma-GTP, one with thrombocytopenia, and one with eosinophilia each, but these abnormal values were slight and transient. In summary our clinical study showed that Imipenem/Cilastatin sodium was a very effective antibiotic in treatment on moderate or serious UTI or preventive use for infections in compromised hosts. Considering the features of this agent, it might be more effective and useful for clinical use in treatment on polymicrobial infections including stubborn organisms than any other antimicrobial compounds. Furthermore, it was safe and well tolerable in a long term treatment.

We studied the absorption and excretion as well as the clinical effect of rokitamycin (RKM, TMS-19-Q) dry syrup. The results we found are summarized as follows: 1. When 3 pediatric patients were medicated orally with a single dose of 10 mg/kg of the drug, its peak concentrations of 0.75 and 0.51 microgram/ml appeared in the blood in 30 minutes after administration in 2 patients, and of 0.21 microgram/ml in 1 hour in the other patient. At 4 hours after administration, its concentration in the blood was 0.07-0.08 microgram/ml in all of the patient, and at 6 hours, it was undetectable. T1/2 values were 1.05-2.08 hours. First 6-hour urinary recovery rates of the drug in the first 2 patients were 1.52 and 1.11%, respectively. 2. Twenty-four patients with 25 diseases were medicated with 7.14-12.5 mg/kg of the drug 3-4 times daily for 4-10 days. The patients consisted of 12 with tonsillitis, 7 with bronchitis, 3 with colitis, one each with Haemophilus influenzae pneumonia, mycoplasmal pneumonia, and pertussis. Clinical responses to the treatment were excellent in 7, good in 13, and poor in 5, with an efficacy rate of 80.0%. Bacteriologically, of 17 isolates whose changes were followed, 8 were eradicated, 1 decreased, and 8 remained unchanged, with an eradication rate of 47.1%. 3. No adverse reactions to the drug were observed in any of these patients, while abnormal laboratory test values observed were slight eosinophilia and also slight elevations of S-GOT and S-GPT in one of the patients.(ABSTRACT TRUNCATED AT 250 WORDS)

Ceftizoxime (CZX) was evaluated for absorption and excretion as well as for therapeutic effectiveness in neonates and premature infants. The following results were obtained. 1. Serum CZX concentrations were determined in 8 neonates or premature infants who were not more than 6 days old. Serum concentrations of the drug were examined in 6 neonates and/or premature infants after intravenous administration of about 20 mg/kg body weight. Average concentration at 1/2, 2, 4 and 6 hours after administration were 52.3, 36.4, 26.7 and 16.7 micrograms/ml, respectively. Serum concentrations in the other 2 infants who were given 29.7 and 25.1 mg/kg, were as high as 71 and 94 micrograms/ml at 1/2 hour and 22.1 and 39 micrograms/ml at 6 hours, respectively. Serum half-lives in 5 of the 6 mature neonates ranged from 2.36 to 3.34 hours, with averaged 2.75 hours, but was exceptionally long, 7.92 hours, in the other one. Half-lives in the 2 premature infants were 4.14 and 4.90 hours. 2. The therapeutic effectiveness on bacterial infection was evaluated for 10 newborn infants. Intravenous doses of 16.9 to 24.6 mg/kg were given in b.i.d. or t.i.d. regimen to 4 cases with pneumonia and 2 with septicemia, urinary tract infection and fetal infection each. To 1 infant with septicemia complicated with cephalohematoma, higher doses ranged from 21.8 to 49.8 mg/kg were given t.i.d. or q.i.d. Therapeutic efficacies were assessed as "Excellent" in 3, "Good" in 6, and "Poor" in 1, with an efficacy rate of 90.0%. Eradication of bacteria was complete in 2 infants each with Escherichia coli-induced septicemia or urinary tract infection. 3. For prophylactic use, the drug was given to 8 newborn infants in intravenous doses of 17.5 to 29.1 mg/kg b.i.d. or t.i.d. and no infection occurred in 7 cases. 4. No adverse reactions were obtained. Slight and transient increases in platelet count, GOT and GPT in 1 case and eosinophilia in another were observed. 5. These results suggested that CZX in an intravenous dose of 20 mg/kg b.i.d. or t.i.d. regimen in newborn infants up to 7 days of age would be effective and safe for the treatment of neonatal bacterial infections.

Twenty five children were treated with rokitamycin (RKM) and its clinical efficacy and side effects were evaluated. Ages of the patients ranged from 13 days to 10 years. Doses of RKM ranged 17.1-39.3 mg/kg/day for 2.3 to 17.7 days. Twenty four patients including 8 Mycoplasma pneumonia, 5 bronchopneumonia, 6 bronchitis, 2 streptococcosis, 1 otitis media, 1 tonsillitis and 1 Chlamydia conjunctivitis were evaluated for clinical efficacy. Results were excellent in 7, good in 12, fair in 4, and poor in 1 patient. One patient was excluded from the evaluation, because the patient was treated with erythromycin before entering this study. Out of the 25 patients, 3 cases showed eosinophilia, 2 cases showed elevated GOT and GPT but no adverse clinical signs due to RKM were observed. The pharmacokinetics of RKM was studied in 5 patients whose ages ranged from 8 to 12 years. Plasma peak concentrations of RKM in 2 patients were 0.14 and 0.16 micrograms/ml at 30 minutes after doses of 5 mg/kg. Peak concentrations in 3 patients ranged from 0.32 to 1.02 micrograms/ml after doses of 10 mg/kg. Portions of the drug excreted into urine within 6 hours were 0.49 and 1.03% in 2 patients each of whom was given doses of 5 mg/kg, and ranged from 1.16 to 1.30% in 3 patients, each given 10 mg/kg. Metabolic products in urine within 4 hours after doses of 5 to 10 mg/kg were studied in 4 patients. Leucomycin A7 and leucomycin V accounted for almost 90% of all the related compounds excreted.

Subjects were in-patients with bacterial urinary tract infections, ranging in age 4 months to 11 years 4 months. As a rule, daily dose was either four 125 mg (in potency) suppositories or four 125 mg (in potency) oral form given at 6-hour intervals over a period of 5 days. The number of children subjected to this study was 105. These children were divided into 2 groups (suppository 54; oral form 51) with matched pretreatment background factors. Therapeutic effectiveness rates were 70.4% for the suppository and 66.7% for the oral form, and no significant difference was observed between the 2 groups. Rates of efficacy by severity, presence or absence of underlying and/or complication diseases, daily dose and causative microorganisms did not differ significantly between the 2 groups. There was no significant difference in time-courses of improvement of clinical signs and symptoms between the 2 groups. Eradication rates for causative microorganisms were 65.9% for the suppository and 62.5% for the oral form. Most frequently isolated causative microorganisms were Escherichia coli and Proteus mirabilis. No significant differences were recognized in the therapeutic effect and usefulness evaluated by physicians in charge. The frequency of side effects did not differ significantly between the suppository group (6 with diarrhea and 1 with anal pain: 12.1%) and the oral form group (5 with diarrhea, 1 with displeasure and 1 with vomiting: 12.7%). Abnormal laboratory findings appeared in 6 cases (2 with eosinophilia, 2 with increased GOT and 2 with increased GPT) in the suppository group and 7 cases (2 with eosinophilia, 2 with thrombocytosis, 2 with increased GOT and 1 with increased GPT) in the oral form group.
