Bacteriological, pharmacokinetic and clinical studies on cefpodoxime proxetil (CPDX-PR, CS-807), a new oral cephem antibiotic, were carried out in the field of pediatrics. The results obtained are summarized as follows. 1. Antibacterial activities of R-3746 (Na-salt of cefpodoxime (CPDX] against clinically isolated strains of Streptococcus pneumoniae, Streptococcus pyogenes, Staphylococcus aureus, Enterococcus faecalis, Branhamella catarrhalis, Escherichia coli, Proteus mirabilis and Haemophilus influenzae were compared with those of cefaclor, cephalexin and cefadroxil. R-3746 is superior to other antibiotics against S. pneumoniae, S. pyogenes, B. catarrhalis and Gram-negative rods. 2. Serum concentrations of CPDX after administration of CPDX-PR at doses of 3 mg/kg (fasting), 6 mg/kg (non-fasting) and 6 mg/kg (fasting) were determined. Mean AUC (area under curve)'s of CPDX obtained were 9.60, 31.35 and 17.89 micrograms.hr/ml, respectively for the 3 dosages. The mean half-lives of CPDX were 3.35, 1.88 and 1.76 hours, respectively. The mean urinary recovery rate within 8 hours after administration of CPDX-PR at a dose of 3 mg/kg (fasting) was 39.2%. 3. CPDX-PR was administered to 37 pediatric patients with various bacterial infections (pyelonephritis 9, cystitis 4, pneumonia 7, acute bronchitis 3, otitis media 2, tonsillitis 10, subcutaneous abscess 1 and purulent lymphadenitis 1). The overall clinical efficacy rate was 91.9% and the overall bacteriological eradication rate was also 91.9%. 4. No adverse reactions were observed. Abnormal laboratory findings were moderate, eosinophilia in 2 and slight elevation of GOT and GPT in 1. The taste and the odor of the CPDX-PR preparation was sufficiently tolerable. From the above results we have concluded that CPDX-PR is a useful oral antibiotic in the treatment of bacterial infections in children.

Sulbactam/Ampicillin (SBT/ABPC), a combination at a fixed ratio of ABPC and SBT which is an irreversible inhibitor of beta-lactamase in a 2:1 ratio, was clinically evaluated for its efficacy and safety in 24 patients with ages from 5 month-old to 12 years old with bacterial infection. The results obtained are summarized as follows. 1. A pharmacokinetic study following 30 mg/kg SBT/ABPC administration by 30 minutes drip infusion or intravenous bolus injection showed that mean half-lives of SBT and ABPC were 48.9 minutes and 40.2 minutes, respectively, and mean urinary excretion rates of SBT and ABPC in the first 6 hours were 67.1% and 48.3%, respectively. 2. SBT/ABPC was administered to 14 patients with bronchopneumonia, 4 patients with tonsillitis, a patient each with acute upper respiratory infection, with submandibular lymphadenitis, with phlegmon, with enterocolitis, with pyelonephritis and with cystitis at a daily dosage of 88.2-133.3 mg/kg, divided into 3 or 4, by intravenous bolus injection or by 30 minutes drip infusion. Clinical responses of the 24 patients were as follows: excellent: 17 patients, good: 7 patients. The efficacy rate was 100%. 3. Neither clinical adverse reactions nor abnormal laboratory test values, except slight eosinophilia in a patient and an elevation of GOT, GPT in another were observed. 4. MICs of SBT/ABPC against 7 strong beta-lactamase producing strains isolated from some of the patients were as follows. MIC against a strain of Staphylococcus aureus was 3.13 micrograms/ml, MICs against 2 out of 5 strains of Branhamella catarrhalis were 0.10 microgram/ml and those of the remaining 3 strains were 0.20 microgram/ml. MIC against a strain of Haemophilus parainfluenzae was 3.13 micrograms/ml. 5. These data described above show that SBT/ABPC has excellent bactericidal capacity against beta-lactamase producing bacteria as well as beta-lactamase non-producing Gram-positive and negative bacteria and suggest that SBT/ABPC is a very useful antibiotic for pediatric patients.

Cefixime (CFIX, Cefspan), a new oral cephem, was used in the treatment of urinary tract infections, and was evaluated for its therapeutic effectiveness and safety at the Department of Urology, Osaka University Hospital and 16 affiliated hospitals. A total of 238 patients were administered daily doses of 200 or 400 mg. Clinical efficacy was assessed on 92 female patients with acute uncomplicated cystitis and 42 patients with complicated UTI according to the Criteria for Clinical Evaluation of Antimicrobial Agents in UTI (3rd ed.) recommended by the Japan UTI Committee, to which we added our own minimum modification. Clinical efficacy was evaluated as excellent in 57 of the acute uncomplicated cystitis cases, moderate in 33 and poor in 2, with an overall clinical effectiveness rate of 98%. Clinical efficacy was evaluated as excellent in 12 of the complicated UTI cases moderate in 12 and poor in 18, with an overall clinical effectiveness rate of 57%. In one case of uncomplicated pyelonephritis, CFIX showed an excellent efficacy. Of the total of 102 bacterial strains isolated from uncomplicated UTIs, 95 (93%) were eradicated by CFIX, while 36 (72%) eradicated in 50 strains isolated from complicated UTIs. Subjective adverse reactions were seen in 4 cases (1.7%) of the 236 patients, as generalized pruritus and upper gastrointestinal discomforts. Abnormal laboratory findings were recorded in 6 out of 141 cases. They were increases in serum GPT, GOT, alkaline phosphatases, total bilirubin, as well as increases in peripheral leukocytes. These adverse symptoms and abnormal laboratory findings disappeared after the termination of CFIX administration. CFIX might therefore be considered as a clinically useful oral antibiotic in the treatment of UTI.

The clinical effectiveness of a new synthetic pyridoncarboxylic acid derivative, norfloxacin (NFLX: Baccidal) was studied in the urological field. NFLX was given clinically to 50 patients with urogenital tract infections; 40 cases were acute simple cystitis and 10 cases were complicated UTI satisfied the criteria of the UTI committee. Thirty two bacterial strains were isolated from the group of acute simple cystitis and 10 bacterial strains were isolated from the group of complicated UTI. Susceptibility of NFLX by the method of distribution and disk sensitivity was 97% in the former group and 89% in the latter group. The overall clinical efficacy rate estimated by the criteria of the UTI committee in 32 cases with acute simple cystitis was 97% and in 10 cases with complicated UTI was 60%. The incidence of side effect was 8.0% (4/50). All of these side effects which were nausea, abdominal fullness and headache may be attributable to the administration of NFLX. No abnormal laboratory findings were observed except for elevation in GOT and GPT values in 1 case (4.0%), which returned to normal after NFLX treatment. Therefore NFLX is suggested to be a clinically useful and safe drug in the treatment of UTI.

A patient with Jo-1 antibody-associated polymyositis (Jo-1 PM) had a Karnofsky score of 40% and severe muscle, liver and lung damage that was refractory to standard therapy. The female patient received an autologous T-cell-depleted haematopoietic stem cell transplant (HSCT) after myeloablative conditioning. The transplant procedure was complicated by severe adult respiratory distress syndrome (ARDS) and adenovirus-associated haemorrhagic cystitis as well as cytomegalovirus (CMV) reactivation. The patient's creatinine phosphokinase (CPK) and alanine transaminase (ALT) values were normal on day 21. The patient's strength has improved remarkably and her dyspnoea is subjectively improved. At 15 months after the transplant, the patient was well with a Karnofsky score of 80% and had been off any therapy, including steroids, for 14 months.

Busulfan (Bu) is an important component of some myeloablative regimens prior to stem cell transplantation (SCT). Over the last few years it has been shown that other drugs administered concomitantly can influence Bu pharmacokinetics. In the present study, we compared Bu concentrations (trough levels) in three groups of patients. Group A (n=5) received metronidazole as graft-versus-host disease prophylaxis during Bu treatment. Group B (n=9) received Bu only for 2 days followed by 2 days of Bu and metronidazole. Group C (n=10) was a control group that received Bu without metronidazole. The mean Bu levels for Group A receiving metronidazole during conditioning was significantly (P<0.001) higher (948+/-280 ng/ml), compared to those observed in the control group (507+/-75 ng/ml). In Group B, the administration of metronidazole resulted in a significant (P<0.001) increase in Bu levels (807+/-90 ng/ml) during the last 2 days, compared to 452+/-68 ng/ml during the first 2 days. In Group A, one patient died with multiorgan failure, three experienced veno-occlusive disease (VOD) and one developed hemorrhagic cystitis. Elevated liver transaminases (AST, ALT) and bilirubin were detected in all Group A patients. In Group B, six patients had elevated liver function tests but no VOD was observed. We conclude that metronidazole should not be administered simultaneously with Bu to avoid the high plasma levels of Bu, which may lead to severe toxicity and/or treatment related mortality.
