Clinical efficacy and safety of cefprozil (CFPZ, BMY-28100), a newly developed oral cephalosporin, were studied in our pediatric department. Clinical effectiveness, bacteriological effectiveness and side effects were studied in 116 pediatric patients with ages ranging 4 months to 11 years. CFPZ was given 4.6-14.1 mg/kg daily in 3 times for 3-10 days. Clinical efficacies were evaluated in 112 patients, and the therapeutic effectiveness were excellent in 1 and good in 6 for 7 patients with acute pharyngitis, excellent in 24 and good in 26 for acute purulent tonsillitis, excellent in 3, good in 8 and fair in 1 for acute bronchitis, excellent in 21, good in 7, fair in 1 and poor in 1 for acute pneumonia, excellent in 1 acute purulent parotitis, excellent in 2 and good in 7 for acute UTI, good in 1 impetigo, fair in 1 periproctal abscess and good in 1 acute enteritis. The effectiveness rate was 96.4%. Bacteriologically, 4 strains of Staphylococcus aureus (beta-lactamase producing strains), 1 strain of Staphylococcus epidermidis (beta-lactamase producing strain), 2 strains of Streptococcus pneumoniae, 2 strains of Streptococcus agalactiae, 4 strains of beta-Streptococcus, 1 strain of Klebsiella pneumoniae (beta-lactamase producing strain) and 1 strain of Salmonella C2 were all disappeared, and of 22 strains of Streptococcus pyogenes, 20 strains were disappeared, 1 was decreased and 1 was unknown, of 5 strains of Escherichia coli (3 beta-lactamase producing strains), 4 were disappeared and 1 was decreased, of 29 strains of Haemophilus influenzae (14 beta-lactamase producing strains), 14 were disappeared, 11 were decreased, 3 persisted and 1 was unknown and of 2 strains of Haemophilus parainfluenzae (1 beta-lactamase producing strain), 1 was disappeared and 1 persisted. The bacteriological eradication rates for Gram-positive bacteria and Gram-negative bacteria were 97.1% and 56.8%, respectively, and the drug was especially effective against Gram-positive bacteria. No side effects nor refusal of ingestion were observed. As abnormalities in laboratory test results, 3 cases of elevation of eosinophil counts and 1 of elevation of platelet counts were observed. In conclusion, CFPZ was considered to be a safe and highly effective antibiotic in pediatric infections.

So far, no ideal study providing an exhaustive knowledge of acute pharyngitis epidemiology has been carried out. What is available now is a number of investigations, all with deficiencies, which concern the duration of the disease (there may be seasonal variations), its limits in space and, above all, the number of pathogens sought for. A well-organized investigation span over at least one year, involve a fairly wide range of age-groups and be repeated in several countries. Bacterial epidemiology is dominated by beta-haemolytic streptococci group A, but other streptococcal groups, notably group C, have been incriminated. Other responsible bacteria, such as Haemophilus spp., Staphylococcus spp. and Corynebacterium spp., are extremely rare but most probable. Mycoplasma pneumoniae and perhaps Chlamydia pneumoniae are probably found more frequently. Rheumatic fever--which had virtually disappeared in medically advanced countries due to a higher level of life and to the general use of penicillin therapy--has reappeared in recent years, as shown by a few North-American epidemics. Such epidemics have come on time to remind us that we should be vigilant and continue, as in the past, to treat all streptococcal foci systematically, in order to prevent the occurrence of rheumatic fever.

Clinical evaluation in pediatrics on cefdinir (CFDN, FK482) (5% fine granules), a new oral cephem, was performed. 1. CFDN was administered to 112 pediatric patients with ages between 1 month to 13 years with various infections. Dose levels used were 3.0-8.9 mg/kg (mean 5.1 mg/kg) t.i.d. for 3-14 days (mean 6.7 days). The studied patients included 2 patients with scarlet fever, 6 with acute pharyngitis, 6 with acute rhinopharyngitis, 52 with acute purulent tonsillitis, 8 with acute bronchitis, 24 with acute pneumonia, 7 with acute urinary tract infections, 1 with acute vaginitis, and 6 with impetigo. Total doses ranged from 0.6 to 4.05 g. One hundred eleven of the 112 patients were evaluated for clinical efficacy and all the patients were evaluated for safety. 2. Clinical effects were excellent in 51 cases, good in 57, and fair in 3 with an extremely high efficacy rate of 97.3%. Efficacy rates were 100% in scarlet fever, acute pharyngitis, acute purulent tonsillitis, acute bronchitis, acute vaginitis and impetigo, and 83.3%, 95.7%, 85.7% in acute rhinopharyngitis, acute pneumonia, and acute urinary tract infections, respectively. Good clinical effects were observed regardless of diseases. 3. Causative organisms were identified in 79 cases, of which 71 were found to be monobacterial infections and 8 were found to be multi-bacterial infections. In mono-bacterial infections, clinical efficacies were 100% for those caused by Staphylococcus aureus/Streptococcus pyogenes/Streptococcus pneumoniae/beta-Streptococcus except those in A and B groups with an overall efficacy of 100% against Gram-positive cocci (GPC) and they were 89.5%, 100%, 100% for those caused by Haemophilus influenzae, Haemophilus parainfluenzae, and Escherichia coli, respectively, with an overall efficacy of 90.3% in Gram-negative rods (GNR). In multi-bacterial infections also, a clinical efficacy of 100% was obtained. 4. Bacteriological effects were studied for 89 strains in the 79 cases. The eradication rate for a few strains of S. pneumoniae was low, 25%, but it was 100% for S. aureus, with the same results for S. pyogenes, and beta-Streptococcus. The eradication rate on GPC was high 94.1%. Among GNR, 66.7% of E. coli, 50.0% of H. influenzae, and 71.4% of H. parainfluenzae was eradicated. The overall eradication rate for GNR was 55.3%, lower than that for GPC. Microbial substitutions were observed in 13 cases, with Haemophilus sp. replacing other bacteria. 5. Diarrhea and soft stools were noted in 4 and 2 patients, respectively. The severity of these side effects, however, was slight and it was possible to continue the CFDN treatment.(ABSTRACT TRUNCATED AT 400 WORDS)

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)

Cefixime (CFIX) was evaluated clinically in pediatric respiratory tract infections, particularly those caused by Haemophilus influenzae: 1. The total number of children in this study treated with CFIX was 232, out of which 215 cases were evaluated for clinical efficacy and 224 cases were investigated for safety. A daily dosage of 3-6 mg/kg/day was given divided into 2 to 3 times daily for 3-15 days. 2. Causative organisms were identified in 146 cases, out of which 128 cases were found to be single microbial infections and 18 cases were mixed infections. In single microbial infections, clinical efficacy was 100% for those caused by H. influenzae/Haemophilus parainfluenzae, and was 95% for Streptococcus pyogenes with an overall efficacy of 96.9%. In mixed infections, the clinical efficacy was 100% for those caused by a combination of H. influenzae and Streptococcus pneumoniae, and the overall rate was 94.4%. An involvement of H. influenzae was observed in 108 cases with a clinical efficacy rate of 99.1%, and definite involvement of beta-lactamase secreting strains of H. influenzae was found in 32 cases with a clinical efficacy of 96.9%. 3. Bacteriological effect was studied for 164 strains identified in 146 cases, and eradication rates were 89.5% for H. influenzae, 100% for H. parainfluenzae and S. pyogenes, and 71.4% for S. pneumoniae. The overall eradication rate was 91.4%. Superinfection was observed in 21 cases. MICs against 78 strains of H. influenzae were in a range of less than or equal to 0.10 microgram/ml regardless of beta-lactamase production, and far superior to cefaclor and amoxicillin. MICs against S. pyogenes and S. pneumoniae were in ranges of less than or equal to 0.10 microgram/ml and 0.39 micrograms/ml, respectively. 4. Clinical efficacy was 93.0% in 215 cases (excellent: 136, good: 64, fairly good: 10, poor: 5). CFIX attained a high efficacy in the range of 89.4-95.7% in acute pharyngitis, acute tonsillitis, acute bronchitis and acute pneumonia. 5. Safety was monitored in 224 cases and there were only one case of loose stool and another of diarrhea as side effects. There were no abnormal findings in 31 cases of the laboratory test. In conclusion, it was confirmed that CFIX is excellent and safe in the treatment of the respiratory tract infections.

The efficacy rate, minimal inhibitory concentrations (MICs), and resistance of fluoroquinolone agents against causative organisms in respiratory tract infections from January to March, 1988 were investigated. Of 333 pathogenic strains 85% consisted of 5 major causative organisms of respiratory tract infection (Haemophilus influenzae, Pseudomonas aeruginosa, Streptococcus pneumoniae, Branhamella catarrhalis, and Staphylococcus aureus). In 61 (59 cases) of these 333 strains, including 3 cases of acute pharyngitis, 5 of acute bronchitis, 3 of pneumonia, and 48 of chronic lower respiratory tract infection fluoroquinolone agents were administered. The efficacy rate was 76.3% in all cases, and 75% in cases with chronic lower respiratory tract infection. The fluoroquinolone agents were 100% effective in H. influenzae and B. catarrhalis, though the efficacy rate was 67% in S. aureus and 40% in P. aeruginosa. The susceptibility of all strains to fluoroquinolone agents were investigated. There was no resistant strain in H. influenzae and B. catarrhalis, though resistant strains to fluoroquinolone agents have increased in S. aureus and P. aeruginosa. The efficacy rate was investigated using the MIC of administered fluoroquinolone agent against causative organisms. It is surmised that the efficacy of that agent has an MIC of 1.56-3.13 micrograms/ml.

The epidemiology of community-acquired respiratory tract infections (RTI) is reviewed with emphasis on acute pharyngitis, otitis media, sinusitis, epiglottitis and pneumonia. The numerical importance of upper respiratory tract infections is stressed and their economic impact discussed. Community-acquired pneumonia, although less common, is a more serious infection with a frequent requirement for hospitalization. The heterogeneous microbial aetiology of RTI is stressed, together with the impact this has on chemotherapeutic choice. The latter is likely to remain largely empirical and based on the prevalence of identified pathogens, spectrum of activity and the pharmacokinetic behaviour of the selected agents. The increasing frequency of resistance among respiratory pathogens, notably Haemophilus influenzae, and to a lesser extent Streptococcus pneumoniae, together with the high incidence of beta-lactamase production among Branhamella catarrhalis is of concern. In addition, the issue of beta-lactam inactivation by commensal bacteria suggests that chemotherapeutic strategies for the control of community-acquired respiratory tract infection might justifiably be reconsidered.

The bacteriology of the isolates from the sputum or the throat swab of patients with respiratory infections visiting a doctor in private practice in Sendai city during the period from March in 1988 to February in 1989 was documented, and their sensitivity to 45 antimicrobial agents was determined. Of the 568 patients, 514 cases had acute pharyngitis, 8 cases each had acute tonsillitis and acute bronchitis, 7 cases were acute pneumonia, 6 cases had herpangina, 18 cases had hand-foot-mouth disease with the signs of respiratory infections, 5 cases had varicella with the signs of respiratory infections and 2 cases were mumps with the signs of respiratory infections. Three hundred strains of potential (greater than or equal to 10(7) CFU/ml) pathogens were recovered from 293 of the 568 cases, which consisted of 124 strains of Haemophilus influenzae, 58 strains of Streptococcus pneumoniae, 45 strains of Staphylococcus aureus, 26 strains of Branhamella catarrhalis, 25 strains of Streptococcus pyogenes, 9 strains of Klebsiella pneumoniae and 13 strains of other species, not including non-fermentile gram-negative bacteria such as Pseudomonas aeruginosa and Acinetobacter calcoaceticus. Staphylococcus aureus and other strains were documented simultaneously in 6 out of 7 cases in which multi-organisms were recovered. Many strains of Staphylococcus aureus were isolated from young patients throughout the year. On the other hand many strains of Branhamella catarrhalis were isolated from elderly patients in winter. The sensitivity of 45 antimicrobial agents of 231 of 300 strains was determined by sensitivity disks (EIKEN, Japan). No strain of the Haemophilus influenzae in this study was resistant to ampicillin. None of the Streptococcus pneumoniae and Streptococcus pyogenes was resistant to ampicillin or cefazolin. None of the Staphylococcus aureus was resistant to cloxacillin, cefazolin, gentamicin or ofloxacin. We conclude from the above results that antibiotic-resistant strains are found presumably only in a very few cases in primary care clinic.

Cefodizime (THR-221, CDZM), a new cephalosporin antibiotic, was evaluated for its safety and efficacy in 27 children with various bacterial infections. The episodes of infections included pneumonia (6 cases), bronchopneumonia (11 cases), lung abscess (1 case), acute pharyngitis (2 cases), cervical lymphadenitis (1 case), infected cephalohematoma (1 case), urinary tract infection (1 case), sepsis (2 cases) and purulent meningitis (2 cases). CDZM was effective in all but one, and its efficacy rate was 96.3%. The main etiologic pathogens were Staphylococcus aureus, Haemophilus influenzae, Haemophilus parainfluenzae, Streptococcus pneumoniae, Streptococcus agalactiae, Escherichia coli, Citrobacter freundii and Branhamella catarrhalis. The elimination rate was 92.3%. As adverse reactions or abnormalities, diarrhea was encountered in 4 cases. A slight elevation of serum transaminases or eosinophils was observed in 4 cases. The serum half-life was approximately 1.8-1.9 hours in children after intravenous bolus injections. Concentrations of CDZM in cerebrospinal fluids were well above MIC values of CDZM against those organisms responsible for the infections. The data suggest that CDZM is a safe and effective antibiotic when used in children with bacterial infections including purulent meningitis.

Cefodizime (THR-221, CDZM), a new parenteral cephalosporin, was evaluated for its efficacy and safety in 20 children with bacterial infections (Table 1), and the following results were obtained. 1. CDZM was administered in 3 or 4 divided doses at daily dosages ranging from 54.5 to 84.2 mg/kg administered by 30 minutes drip infusion or intravenous injection to 20 patients (7 cases of acute tonsillitis, 6 cases of pneumonia, 2 cases each of bronchitis and suppurative cervical lymphadenitis, and 1 case each of acute pharyngitis, acute enteritis and furunculosis) and the following clinical results were obtained: excellent, 7 cases; good, 11 cases; fair, 2 cases. The overall efficacy rate was 90% (Table 4). 2. MICs of CDZM against 15 strains of isolated organisms are shown in Table 2. MICs against all 7 strains of Haemophilus influenzae were less than 0.025 micrograms/ml. MIC against 1 out of 5 strains of Streptococcus pneumoniae was 0.05 micrograms/ml and those against 2 strains were 0.10 micrograms/ml and against the other 2 were 0.20 micrograms/ml. MICs against 3 strains of Staphylococcus aureus were 1.56, 25 and higher than 100 micrograms/ml, respectively. 3. No clinical adverse reaction was observed in any of the 20 patients. Eosinophilia was observed in 2 cases. A slight elevation of S-GOT was found in 1 patient (case No. 8) and moderate elevation of S-GOT and S-GPT in another (case No. 18) (Table 4). In case No. 18, the S-GOT and S-GPT activity improved after the administration of the drug was stopped.(ABSTRACT TRUNCATED AT 250 WORDS)
