Cefteram pivoxil (CFTM-PI), the pivaloyloxymethyl ester of cefteram (CFTM) in which aminothiazol was also introduced into the 7 position of cephem nucleus, is a new oral cephem antibiotic. CFTM-PI was absorbed through the intestines and hydrolyzed to CFTM by esterases in the intestinal wall and existed in the body fluids as CFTM. A tablet form of this drug has been released in Japan and now a granular form for pediatric patients has been developed. We have determined MICs of 5 drugs (CFTM, cephalexin (CEX), cefaclor (CCL), ampicillin (ABPC), erythromycin (EM], against stock strains and MICs of 6 drugs (CFTM, CEX, CCL, ABPC, methicillin, cloxacillin) against fresh strains from patients received to CFTM-PI, with an inoculum size of 10(6) cfu/ml. A total of 149 strains included Gram-positive cocci i.e. Staphylococcus aureus (11), Streptococcus pyogenes (85), Streptococcus agalactiae (16) and Streptococcus pneumoniae (4), and Gram-negative rods i.e. Haemophilus influenzae (11), Bordetella pertussis (11), Escherichia coli (9), Proteus mirabilis (1) and Morganella morganii (1). The granular form of CFTM-PI was administered to 9 boys (age: 8 years 3 months approximately 10 years 10 months) to determine serum and urinary concentrations of the drug and its urinary recovery rates using bioassay. Doses of 1.5, 3.0 and 6.0 mg/kg were given orally 30 minutes after meal to 3 boys, respectively. Urinary concentrations and its urinary recovery rates of T-2525A, a main metabolite of CFTM, were determined using high performance liquid chromatography (HPLC). To study clinical and bacteriological effects of this drug, a mean daily dose of 3.3 mg/kg divided 3-4 times a day (3 times: 133 cases, 4 times: 9 cases) was administered for 8 days on the average to a total of 142 cases with pharyngitis (22), tonsillitis (12), acute bronchitis (3), pneumonia (11), pleurisy (1), scarlet fever (28), acute purulent otitis media (16), impetigo (13), abscess (2), purulent lymphadenitis (1) and urinary tract infection (33). Adverse reactions and abnormal effects on laboratory test values attributable to this drug were studied in patients. The results obtained are summarized as follows. 1. With regard to Gram-positive cocci, MICs of CFTM against 11 fresh strains of S. aureus ranged from 3.13 to 6.25 micrograms/ml except for 1 strain, thus CFTM was equally effective to CEX, but less active than the other drugs tested.(ABSTRACT TRUNCATED AT 400 WORDS)

A total of 560 patients were treated in two double-blind, randomized multicenter studies to compare the safety and efficacy of cefixime (400 mg administered once daily) and amoxicillin (250 or 500 mg administered three times daily) for the treatment of bacterial respiratory tract infections. Eighty percent of the 244 patients treated in the lower respiratory tract infections (LRTI) study had acute bronchitis. Streptococcus pneumoniae (13 percent), Haemophilus influenzae (28 percent), and Escherichia coli (10 percent) were the pathogens most frequently isolated from sputum in these patients. Among evaluable patients with positive bacterial culture results at baseline, a favorable clinical response (cured or improved) was obtained in 100 percent of the cefixime-treated patients (22 of 22) and in 96 percent of the amoxicillin-treated patients (23 of 24). Bacteriologic eradication rates were 100 percent and 83 percent for cefixime and amoxicillin, respectively. In the upper respiratory tract infections (URTI) study, 316 patients with pharyngitis (80 percent) or tonsillitis (14 percent) were treated. Group A, beta-hemolytic Streptococcus (69 percent) and H. influenzae (8 percent) were the pathogens most frequently isolated from the throat culture specimens of these patients. Favorable clinical results were obtained in 99 percent of the evaluable cefixime-treated group (n = 73) and in 98 percent of the amoxicillin-treated group (n = 66). The bacteriologic eradication rates were 93 percent and 100 percent, respectively. The adverse experiences reported during both studies were similar in nature and frequency to those reported for other beta-lactam antibiotics with the exception of a higher incidence of altered bowel movement (diarrhea and stool changes) with both drugs. These episodes usually resolved without remedial medication when the treatment was withdrawn. No significant adverse laboratory findings were observed. Results of these trials demonstrate that cefixime at a dosage of 400 mg once daily is an effective and safe oral antibiotic for the treatment of acute respiratory tract infections.

We have carried out laboratory and clinical studies on rokitamycin (RKM, TMS-19-Q). The results are summarized as follows. Serum and urinary concentrations of RKM were determined in 6 children with ages between 6 and 12 years given single oral doses of 5, 10 and 15 mg/kg. Mean serum concentrations peaked at 30 minutes after administration of 5, 10 and 15 mg/kg, and respective peak values were 0.30 microgram/ml, 0.79 microgram/ml and 1.32 micrograms/ml. Biological half-lives for 5, 10 and 15 mg/kg were 2.0 hours, 1.65 hours and 1.36 hours. The 6-hour urinary recovery ranged from 1.11% to 2.58% after administration of 5 mg/kg, and the mean 6-hour urinary recoveries were 1.35% after administration of 10 mg/kg and 2.28% after administration of 15 mg/kg. Therapeutic responses were recorded as excellent or good in 22 (73.3%) of the children, comprising 6 with tonsillitis, 2 with pharyngitis, 4 with bronchitis, 1 with bronchopneumonia, 1 with Mycoplasma pneumonia, 2 with whooping cough, 5 with streptococcal infections, 5 with Campylobacter enteritis, 3 with impetigo and 1 with SSSS. The microbiological effectiveness of RKM on identified pathogens comprising 4 strains of Staphylococcus aureus, 1 strain of Streptococcus pneumoniae, 6 strains of Streptococcus pyogenes, 4 strains of Haemophilus influenzae and 5 strains of Campylobacter spp. was not so satisfactory as evidenced by a eradication rate of 50.0%. No significant side effect due to the drug was observed in any cases. In conclusion, RKM was found to be efficacious and safe for the treatment of bacterial infections in children.

Rokitamycin (RKM), a newly developed macrolide antibiotic with a 16-membered ring, dissolves well under acidic conditions. It has been improved over other macrolides to minimize individual variations in its absorbability. We measured, using the GA-test, variations in gastric acidities of 43 children with ages between 1 to 14 years, and investigated the relationship between gastric acidities and pharmacokinetic values. Also activities (expressed in MICs) of antimicrobial agents were studied against clinically isolated 229 bacterial strains using an inoculum size of 10(6) cells/ml. Tested organisms included Streptococcus pyogenes (77 strains), Streptococcus agalactiae (29), Streptococcus pneumoniae (2), as Gram-positive cocci, and Haemophilus influenzae (1), Haemophilus parainfluenzae (1), Bordetella pertussis (12), Salmonella sp. (4) and Campylobacter jejuni (103) as Gram-negative bacilli. Against stock strains of bacteria, MICs of 10 drugs (RKM, erythromycin (EM), josamycin (JM), midecamycin (MDM), midecamycin acetate (MOM), clindamycin (CLDM), amoxicillin (AMPC), cefaclor (CCL), minocycline, ofloxacin (OFLX] were determined. Against isolates from patients who underwent treatment with RKM, MICs of only 4 drugs (RKM, EM, JM, MOM) were determined. Measurements were made on plasma and urinary concentrations of RKM and its urinary recovery rates after patients including 6 boys with ages between 5 years 1 month and 11 years 6 months were administered with RKM (dry syrup). Two groups of 6 boys were administered between meals with RKM at dose levels of 5 and 10 mg/kg, respectively. Clinical and bacteriological effects of RKM were evaluated for 175 patients including 5 cases of pharyngitis, 3 tonsillitis, 32 pneumonia, 17 mycoplasmal pneumonia, 34 atypical pneumonia, 28 streptococcal infections, 29 Campylobacter enteritis, 4 Salmonella gastroenteritis, and 23 enteritis due to unknown organisms. Five drop-out cases were excluded from the evaluations. In the evaluable cases, an average dose level used was 31.8 mg/kg/day, with a daily dose divided into 3 to 4 administrations and with an average treatment duration of 9 days. Adverse reactions of RKM and its effects on laboratory test values were investigated in these patients including the drop out cases. Obtained results of these studies are summarized below. 1. The GA-test produced pH values indicating that amounts of gastric acid were mostly either normal or high in 42 of the 43 subjects tested (97.7%), and only one low acid case (2.3%) was observed.(ABSTRACT TRUNCATED AT 400 WORDS)

The emergence of beta-lactamase producing bacteria in the microflora in the oropharyngeal cavity was studied in ten healthy volunteers treated with 1 g phenoxymethylpenicillin b.i.d. for ten days. Beta-lactamase activity in saliva was also investigated. A significant increase in the number of beta-lactamase producing strains of Bacteroides species and Fusobacterium nucleatum was observed. One beta-lactamase producing Staphylococcus aureus strain was recovered in one of the volunteers before the penicillin administration started and three Staphylococcus aureus strains produced beta-lactamase after ten days of antibiotic treatment. Beta-lactamase-production in Haemophilus influenzae, Haemophilus parainfluenzae or Branhamella catarrhalis was not observed before, during or after the antibiotic treatment. Beta-lactamase activity was noted in the broth cultures from one volunteer colonized with a beta-lactamase producing Escherichia coli strain. Beta-lactamase activity in saliva was observed in all volunteers, the activity increasing significantly in parallel to the increase of beta-lactamase producing bacterial strains. Beta-lactamase activity in saliva was completely inhibited in vitro by clavulanic acid and p-chloromercurbenzoate and about 70-80 per cent of the activity was inhibited by cefoxitin. The increase of beta-lactamase producing bacteria in the oropharynx as a consequence of penicillin treatment raises doubt as to whether penicillin is the drug of choice in the treatment of tonsillitis caused by group A streptococci when previous treatment has failed.

A total of 29 patients with pediatric infections was treated orally with 21.4-44.4 mg/kg/day of rokitamycin (RKM) dry syrup. The obtained results are summarized as follows. 1. Clinical responses to RKM in 24 evaluable patients were excellent in 2 and good in 3 of 5 patients with tonsillitis and laryngitis; excellent in 3 and good in 5 of 8 patients with bronchitis; excellent in 3, good in 2 and fair in one of 6 patients with bronchopneumonia; excellent in 2 and good in the other of 3 patients with psittacosis; and excellent in 2 of 2 patients with Campylobacter colitis. The overall efficacy rate was 95.8%. 2. Bacteriological responses to the drug were: reduction in 1 and no change in the other of 2 strains of Streptococcus pyogenes; eradication of a strain of Streptococcus pneumoniae and 2 strains of Staphylococcus aureus; eradication of 2 and no change in 3 of 5 strains of Haemophilus influenzae; and eradication of 2 out of 2 strains of Campylobacter spp. 3. Diarrhea was complained of as an adverse reaction to the RKM medication by 1 patient, abdominal pain was reported by another, and anorexia by another of the 27 patients treated. Laboratory examination was performed on some patients, but not abnormal test values were found except in 1 case showing an increase in platelet count from 27.6 to 78.2 X 10(4)/mm8. The results suggested that RKM dry syrup might be a very useful and safe drug for the treatment of pediatric infections.

Pharmacokinetic, bacteriological and clinical studies on sultamicillin (SBTPC) fine granule were carried out in the field of pediatrics. The results obtained are summarized as follows. 1. Antibacterial activities of SBTPC against clinically isolated strains of Haemophilus influenzae, Haemophilus parainfluenzae, Streptococcus pneumoniae, Streptococcus pyogenes, Streptococcus agalactiae, Staphylococcus aureus, Branhamella catarrhalis, and Escherichia coli were compared with those of ampicillin (ABPC). SBTPC was superior to ABPC especially against beta-lactamase producing H. influenzae, E. coli, S. aureus, and B. catarrhalis. 2. Serum concentrations and urinary excretion rates of sulbactam (SBT) and ABPC after administration of SBTPC fine granule at a dose level of 10 mg/kg in 2 cases were determined. Mean half-lives of SBT and ABPC in the serum following oral administration were about 1.33 and 1.61 hours respectively. Mean urinary recovery rates of SBT and ABPC in 6 hours after oral administration at a dose of 10 mg/kg were 58.7% and 49.6% respectively. 3. SBTPC fine granule was administered to 20 pediatric patients with various bacterial infections (pneumonia 8 cases, bronchitis 2, pharyngitis 2, tonsillitis 4, subcutaneous abscess 1 and urinary tract infection 3). The overall clinical efficacy rate was 100% and the overall bacteriological eradication rate was 75%. 4. No adverse reactions were observed except 1 case of loose stool. No abnormal laboratory test values were observed. These results indicate the usefulness of SBTPC fine granule in the treatment of bacterial infections in children.

Sultamicillin fine granules were used orally in 18 pediatric patients with infections in doses ranging 7.3-10.0 mg/kg t.i.d. or q.i.d. The following is a summary of the results: 1. Clinical efficacies in 16 cases with tonsillitis were excellent in 13 cases, good in 2 cases and fair in 1 case. Efficacy in 1 case of bronchitis and 1 case of pneumonia were good. The overall efficacy rate in the 18 cases was 94.4%. 2. Four out of 5 strains of Staphylococcus aureus were eradicated but 1 strain persisted. Three out of 7 strains of Haemophilus influenzae were rated as eradicated, 1 strain as decreased and 3 strains as persisted. Two strains of Streptococcus pyogenes and 3 strains of Haemophilus parainfluenzae were eradicated. The bacteriological efficacy rate for the 17 strains was 70.6%. Four strains out of the 17 were found to produce beta-lactamase and 3 strains were suspected, to produce the enzyme, but of these 7 strains, 5 strains were eradicated. 3. Diarrhea and loose stool were observed as side effects in each of 2 cases. It appeared that diarrhea was related to this drug. A slight elevation of GOT was observed in 1 case in laboratory tests. 4. This drug appears to be easy for children to take in terms of taste and smell.

We have summarized our experience in recovery of beta-lactamase-producing bacteria (BLPB) in head and neck infection (HNI). These HNI include conjunctivitis, serous and chronic otitis media, cholesteatoma, chronic mastoiditis, chronic sinusitis, adenoiditis, recurrent tonsillitis in children and adults, peritonsillar abscess, and retropharyngeal abscess. Beta-lactamase-producing bacteria were found in 262 (51%) of 513 patients with HNI; 72% had aerobic BLPB and 57% had anaerobic BLPB. The infections, where these organisms were most frequently recovered, were adenoiditis (85% of patients), tonsillitis in adults (82%) and children (74%), retropharyngeal abscess (71%), and chronic otitis media (57%). The predominant BLPB were Staphylococcus aureus (49% of patients with BLPB), the Bacteroides-melaninogenicus group (28%), the Bacteroides fragilis group (20%), Pseudomonas aeruginosa (13%), Hemophilus influenzae (5%), and Branhamella catarrhalis (3%). The high incidence of recovery of BLPB in head and neck infections may have important implications on the antimicrobial management of these infections.

Pharmacokinetical, bacteriological and clinical studies of flomoxef (FMOX, 6315-S), a new cephem antibiotic, were conducted in the pediatric field. 1. Mean drug concentrations in the blood after intravenous one shot injection of FMOX 20 mg/kg to 5 children (aged 5-8 years) were 39.7 micrograms/ml at 1/4 hour, 24.1 micrograms/ml at 1/2 hour, 12.2 micrograms/ml at 1 hour, 4.7 micrograms/ml at 2 hours, 1.1 microgram/ml at 4 hours, and 0.3 microgram/ml at 6 hours. The mean half-life in blood was 0.65 hour. Mean concentrations in urine was 3,558 micrograms/ml during 0-2 hours after intravenous injection, 568 micrograms/ml during 2-4 hours, and 117 micrograms/ml during 4-6 hours. The mean 6-hour urinary recovery rate was 72.8%. 2. Clinically, FMOX was administered to 32 children (5 months to 9 years) with infections, i.e. 29 with pneumonia, 1 each with acute purulent tonsillitis, acute purulent lymphadenitis and cellulitis. The treatment was excellent in 24 cases and good in 8. Thus, the efficacy rate was 100%. 3. The bacteriological effect of FMOX was investigated using 11 clinical isolates which were considered to be causative organisms, i.e. 1 strain of Staphylococcus aureus, 1 strain of Streptococcus pneumoniae, 8 strains of Haemophilus influenzae and 1 strain of Haemophilus parainfluenzae. Except one strain (H. influenzae) which was just decreased, all the bacteria were eliminated. 4. No side effect was found at all. As abnormal laboratory findings, elevation of GOT was found in 1 case, thrombocytosis in 2, and eosinophilia in 1 but all the changes were slight and were normalized by the time of re-examination. The above results suggest that FMOX is a useful and safe drug for the pediatric practice just as in the adult field.
