Of the 175 enrolled patients, urine was obtained by clean catch in 138 (79%), catheterization in 35 (20%), first-pass void in 1 (0.6%), and undocumented method in 1 (0.6%). Pyuria was demonstrated in 164 patients (94%), but only 97 (55%) had a positive urine culture. The combination of pyuria and a positive urine culture confirmed UTI in 90 patients (51%). The most commonly prescribed antibiotics were cefdinir in 103 patients (59%), trimethoprim/sulfamethoxazole in 40 (23%), and ciprofloxacin in 23 (13%). The median duration of prescribed therapy was 10 days (interquartile range, 7-10 days). Treatment duration was correlated negatively with age (r = -0.53, P < 0.01).

A number of oral third-generation cephalosporins (cefixime, cefetamet pivoxil, ceftibuten and cefpodoxime proxetil) have been widely trialled and are becoming available. In addition, cefdinir may also be marketed. Compared with first- and second-generation agents, the oral third-generation cephalosporins have an improved antibacterial spectrum and reduced minimum inhibitory concentrations against common Gram-negative pathogens. In contrast, with the exception of cefdinir, they are less active against Staphylococcus aureus. They have favourable pharmacokinetic profiles and are generally administered in once- or twice-daily regimens. They are well tolerated, but cefixime has been associated with a particularly high rate of diarrhoea. Possible clinical indications for the use of oral third-generation cephalosporins include upper and lower respiratory, genitourinary and soft-tissue infections and follow-on treatment of severe infections requiring hospitalisation. At present, these drugs offer no particular clinical advantages over standard therapy in most circumstances. However, they may be considered where there is hypersensitivity to penicillins, a high incidence of resistance to first-line therapy in the community, or failure of standard therapy. Further studies are needed to define the efficacy of oral third-generation agents in the prevention of rheumatic fever and as follow-on therapy for severe infections. The oral third-generation cephalosporins are generally more expensive than standard agents, but detailed studies that include extended costs (e.g. treatment of adverse effects, treatment of clinical failure, return visits to physicians) have yet to be reported.
Patients with acute exacerbations of chronic bronchitis were treated with cefdinir 300 mg bd for 5 days or cefprozil 500 mg bd for 10 days in a prospective, randomized, double-blind, multicentre study. Of the 548 patients enrolled, 281 (51%) were evaluable. The clinical cure rates at the test-of-cure visit were 80% (114/142) and 72% (100/139) for the evaluable patients treated with cefdinir and cefprozil, respectively. Respiratory tract pathogens were isolated from 409 (75%) of 548 admission sputum specimens, with the predominant pathogens being Haemophilus parainfluenzae, Haemophilus influenzae, Staphylococcus aureus and Moraxella catarrhalis. The microbiological eradication rates at the test-of-cure visit were 81% (157 of 193 pathogens) and 84% (166 of 198 pathogens) for the evaluable patients treated with cefdinir and cefprozil, respectively. Adverse event rates while on treatment were equivalent between the two treatment groups. The incidence of diarrhoea during therapy was higher for patients treated with cefdinir (17%) than for patients treated with cefprozil (6%) (P < 0.01), but most cases were mild and did not lead to discontinuation of treatment. These results indicate that a 5 day regimen of cefdinir is as effective and safe in the treatment of patients with acute exacerbations of chronic bronchitis as a 10 day regimen of cefprozil.

The minimum inhibitory concentrations (MICs) of tosufloxacin (TFLX), levofloxacin (LVFX), ciprofloxacin (CPFX), gatifloxacin (GFLX), sparfloxacin (SPFX), azithromycin (AZM), cefteram (CFTM), cefdinir (CFDN) and cefpodoxime (CPDX) against 337 clinical isolates of Streptococcus pneumoniae isolated from Japanese hospital from 1997 to 2002 were investigated by agar plate method. The incidence of penicillin-susceptible S. pneumoniae (PSSP), penicillin-intermediate resistant S. pneumoniae (PISP), and penicillin-resistant S. pneumoniae (PRSP) in each year was studied, and the MICs of antibacterial agents against these strains were determined. As the results, the total incidence of PSSP, PISP, and PRSP was 51.0%, 40.4% and 8.6%, respectively. The incidences of PSSP from 1997 to 2002 were 46.0-55.9%, and were almost definite in each year. In quinolone antibiotics, the differences of antibacterial activity among TFLX, SPFX, and GFLX against PSSP, PISP, and PRSP, were not observed, and these 3 quinolones had potent antibacterial activity. Although CPFX and LVFX showed antibacterial activity as well as other quinolones by 2001, the CPFX-resistant or LVFX-intermediate resistant strains of PSSP were seen with 56.5% and 91.3% in 2002, respectively. Thirty percents of each PSSP, PISP, and PRSP strains were AZM-resistant strains. Such tendency of increase was recognized in PSSP. Against cephem antibiotics, the incidence of intermediate resistant and resistant strains was higher for PISP and PRSP than for PSSP. No difference in the incidence of resistant strains was noted among CFTM, CFDN, and CPDX.

Cefdinir, a new oral 2-amino-5-thiazolyl cephalosporin, inhibited the luminol-amplified chemiluminescence (LACL) response of human neutrophils stimulated by PMA but not opsonized zymosan, in a concentration-dependent but not time-dependent manner. The LACL response to opsonized zymosan in cytochalasin B-treated neutrophils was, however, inhibited by cefdinir. Various cephalosporins, regardless of the presence of a 2-amino-5-thiazolyl moiety, did not significantly alter the neutrophil LACL response triggered by PMA and zymosan. The LACL response induced by the calcium ionophore A23187 and FMLP was also impaired by cefdinir, and this impairment was increased in cytochalasin B-treated neutrophils. Superoxide anion generation by neutrophils, measured in terms of lucigenin-amplified chemiluminescence and cytochrome c reduction, was not altered. Spontaneous and FMLP-induced neutrophil degranulation, assessed by lysozyme and beta-glucuronidase release, were not modified by cefdinir. Furthermore, cefdinir inhibited LACL generation in cell-free systems consisting of H2O2, NaI, and either horseradish peroxidase or a myeloperoxidase-containing neutrophil extract. Orthodianisidine oxidation in these two acellular systems was inhibited by cefdinir. Cefdinir did not alter neutrophil bacterial killing at concentrations that inhibited myeloperoxidase-containing neutrophil extract-dependent reactions induced by soluble stimuli. Taken together, these data strongly suggest that cefdinir directly inhibits the activity of myeloperoxidase-containing neutrophil extract released into the extracellular medium during neutrophil stimulation by soluble mediators, but has no effect on that released into the phagolysosome during phagocytosis. This unusual property of a member of the beta-lactam family could be of interest in modulating the exaggerated inflammatory process often associated with infectious diseases.

We investigated the susceptibility to antibacterials of 194 strains of Haemophilus influenzae isolated from medical facilities in Gifu prefecture between 2005 and 2006, and compared these results with those of 280 strains of H. influenzae isolated between 1999 and 2000. Additionally, the strains that had been separated between 2005 and 2006 were examined for beta-lactamase (BL) production, the mutation of ftsI gene coding for PBP3, the bla gene coding for TEM type of BL and the serotype. Referring to the CLSI breakpoint, H. influenzae strains were classified into the following categories: (1) beta-lactamase-negative ampicillin-susceptible (BLNAS) strains, which showed BL negative, ampicillin (ABPC) and ampicillin/sulbactam (ABPC/SBT)-MIC < or = microg/ml, (2) beta-lactamase producing ampicillin-resistant (BLPAR) strains, which showed BL producing and ABPC/SBT-MIC < or =2 microg/ml, (3) beta-lactamase-negative ampicillin-resistant (BLNAR) strains, which showed BL negative, ABPC and ABPC/SBT-MIC > or =2 microg/ml, (4) beta-lactamase-producing amoxicillin/clavulanic acid-resistant (BLPACR) strains, which showed BL producing and ABPC/SBT-MIC > or =4 microg/ml. The prevalence of each resistance class were 71.8% for BLNAS, 7.9% for BLPAR, 19.6% for BLNAR and 0.7% for BLPACR in strains isolated between 1999 and 2000. But they were 38.1% for BLNAS, 4.6% for BLPAR, 54.6% for BLNAR and 2.6% for BLPACR in strains isolated between 2005 and 2006, indicating that the percentage of BLNAS and BLPAR decreased and that of BLNAR and BLPACR increased from 1999-2000 to 2005-2006. On the basis of ftsI substitutions and having bla gene, the strains isolated between 2005 and 2006 were classified into the following distribution: 24.2% for gBLNAS, 4.1% for gBLPAR, 10.8% for gLow-BLNAR, 57.7% for gBLNAR, and 3.1% for gBLPACR-II. Ratio of BLNAR belonging to gBLNAR and gLow-BLNAR based on the ftsI substitutions and having bla gene was higher than that based on the susceptibility pattern. The MIC50 and MIC90 for those strains isolated between 2005 and 2006 were as follows; 0.0039, 0.0156 microg/ml for garenoxacin, 0.0078, 0.0156 microg/ml for tosufloxacin and ciprofloxacin, 0.0156, 0.0313 microg/ml for levofloxacin, 0.0313, 0.0625 microg/ml for norfloxacin, 0.0625, 0.25 microg/ml for piperacillin/ tazobactam, 0.0625, 0.5 microg/ml for piperacillin, 0.125, 0.25 microg/ml for ceftriaxone and cefditoren, 0.5, 1 microg/ml for cefteram, chloramphenicol and tetracycline, 0.5, 2 microg/ml for cefotaxime, 2, 8 microg/ml for ampicillin, ampicillin/sulbactam and cefdinir. In comparison with the values for the strains isolated between 1999 and 2000, the MIC50s of beta-lactam for the strains isolated between 2005 and 2006 increased over 4 times.

Pharmacokinetic, bacteriological, and clinical studies on cefdinir (CFDN, FK482) (10% fine granules), a new oral cephem, were performed in pediatrics. 1. Bioequivalencies of plasma concentrations and urinary excretions of CFDN 5% and 10% fine granules were investigated on 3 pediatric patients with ages between 5 to 13 years administered with a drug in fasting state at a dose level of 3 mg/kg using a cross over method. Average plasma concentrations in a group of patients administered with 5% fine granules peaked at 3 hours after administration with a level of 1.05 +/- 0.29 micrograms/ml (mean +/- S.E.) and decreased to 0.12 +/- 0.05 micrograms/ml at 8 hours with a half-life of 1.48 +/- 0.09 hours. In the group administered with 10% fine granules, average plasma concentrations peaked at 2 hours after administration with a level of 1.32 +/- 0.12 micrograms/ml, and decreased to 0.20 +/- 0.11 microgram/ml at 8 hours with a half-life of 1.68 +/- 0.28 hours. The first 8-hour urinary recovery rates of CFDN in the 5% and 10% fine granules groups averaged 19.64 +/- 5.69% and 23.37 +/- 2.36%, respectively. Both average and individual plasma concentrations and urinary recovery rates in the patients of the 10% fine granules group were somewhat higher than those of the 5% fine granules group, but no significant differences were observed between the 2 groups including areas under concentrations. 2. CFDN 10% fine granule preparation was administered to 33 pediatric patients with ages between 1 to 13 years with various infections, and its clinical effects, bacteriological effects and safety were assessed. In 31 of the 33 patients (2 patients were excluded since they were with non-bacterial infections) clinical effects were excellent in all of 9 patients with scarlet fever (3), acute pharyngitis (3) or impetigo (3), excellent in 12 and good in 3 of 15 patients with acute purulent tonsillitis, and excellent in 4 and good in 3 of 7 patients with acute pneumonia. The overall efficacy rate was 100%. Bacteriological effects against causative organisms were evaluated. All the identified Staphylococcus aureus (4 strains) and Streptococcus agalactiae (1) were eradicated. Of 10 strains of Streptococcus pyogenes, 9 strains were eradicated and the other one was reduced. Of 7 strains of Haemophilus influenzae 4 were eradicated, 1 persisted and the fate of the remaining 2 were unknown. The overall eradication rate was 90.0%. Microbial substitutions were observed in 5 patients. The new, replacing bacteria were all Haemophilus spp.(ABSTRACT TRUNCATED AT 400 WORDS)

CE could quench (static quenching) the intrinsic fluorescence of BSA by forming the CE-BSA complex. The main binding forces were considered as hydrogen bonds and Van der Waals forces based on the calculated values of the thermodynamic parameter. The process of binding was spontaneous because Gibbs free energy change was negative. The primary binding site for CE was located at sub-domain II of BSA. The values of Hill's coefficients were less than 1, indicating a negative cooperative effect. Synchronous fluorescence spectra showed that the conjugation reaction between CE and BSA did not affect the conformation of BSA, and the binding site was close to the tyrosine residue.
