During 8 months from October 1986 to May 1987, the clinical efficacy of sulbactam/ampicillin (SBT/ABPC) was evaluated in 63 pediatric inpatients with various infections. Clinical efficacies were evaluable in 58 patients among them (consisting of 2 patients with sepsis, 3 with tonsillitis, 12 with bronchitis, 6 with bronchopneumonia, 24 with pneumonia, 1 with phlegmon, 2 with lymphadenitis, 1 with impetigo and 7 with urinary tract infection) and were excellent in 40 patients and good in 17 with an overall efficacy rate of 98.3%. Bacteriological efficacies were assessed in 25 patients and 27 strains of organisms (consisting of 3 strains of Staphylococcus aureus, 2 Streptococcus pneumoniae, 1 Streptococcus pyogenes, 2 beta-Streptococcus, 1 Gram-positive cocci, 5 Escherichia coli, 1 Enterobacter aerogenes, 7 Haemophilus influenzae, 2 Haemophilus parainfluenzae, 1 Branhamella catarrhalis, 1 Proteus mirabilis and 1 Salmonella subgenus I). Bacteriological eradication rates were 88.9% for Gram-positive organisms, 66.7% for Gram-negative organisms and 74.1% overall. No superinfection was observed in any of patients treated. Side effects and clinical laboratory parameter abnormalities observed consisted of diarrhea in 7 (11.1%) of the 63 patients, eosinophilia in 2 (3.3%) of 61 tested, thrombocytosis in 3 (5.5%) of 55, elevation of direct bilirubin in 1 (3.3%) of 30, elevation of total bilirubin in 1 (3.1%) of 32, elevation of GOT in 4 (6.8%) of 59 and elevation of GPT in 1 (1.7%) of 59 patients tested. As an effect on the hemostatic mechanism of this drug, PIVKA II was detected in 1 patient (4.2%) of 24 tested, but findings of other coagulation tests were normal and none of patients showed bleeding tendency or inhibition of platelet aggregation. From the above results, it appears that SBT/ABPC is an efficacious and safe drug in the treatment of bacterial infections of pediatric patients.

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)

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.

Mupirocin is an investigational topical antibiotic used for treatment and prophylaxis of bacterial skin infections. Mupirocin differs from other antibiotics in its synthesis, structure, and mechanism of action. In vitro, mupirocin possesses antimicrobial activity against staphylococci, streptococci, Hemophilus influenzae, and Neisseria gonorrhoeae. Few studies comparing mupirocin to other topical antibiotics are available. Initial studies comparing mupirocin to inactive vehicle in the treatment of impetigo indicate an overall 92 percent pathogen eradication rate with active drug and 58 percent eradication rate with vehicle. Overall response to treatment of secondary skin infections was favorable in 91 percent of patients treated with mupirocin and 77 percent of those treated with vehicle. Although incidence is not greater than placebo, adverse effects have included pruritus, burning, dry skin, and erythema. Additional trials and clinical use should further help determine the role of mupirocin in the treatment of minor, primary, and secondary skin infections.

Skin and soft tissue infections are common infectious problems in pediatric practice. Recent clinical and pharmacologic evaluations of several new antimicrobial agents have shed new light on the pathogenesis and management of these infections. Staphylococcus aureus now appears to be the most common bacterial isolate in children with impetigo. In patients hospitalized because of skin and soft tissue infections, S. aureus and Haemophilus influenzae type b remain the predominant pathogens. Rational therapeutic approaches to these infections require a recognition of the interplay among the pharmacodynamic, pharmaceutic and pharmacokinetic determinants of effective antimicrobial therapy. Using this approach the therapeutic questions regarding "what drug," "what dose" and "how long to treat" can be approached. Drugs such as the aminopenicillin-beta-lactamase inhibitor combinations may offer rational outpatient therapeutic alternatives, while parenteral cefuroxime and ceftriaxone are more probably the drugs of choice for parenteral therapy. In an age when cost effectiveness must prevail, strategies using ceftriaxone for both inpatient and outpatient management may provide the safest and most cost-effective therapy.

BRL 25000 granules containing 2 parts amoxicillin and 1 part potassium clavulanate were administered to children suffering from acute infections at a daily dose of 50 mg/kg in 3 or 4 divided doses for at least 3 days. Infections included acute airway infections (81), scarlet fever and suspected scarlet fever (4), urinary tract infections (4), impetigo contagiosa (1) and acute colitis (1). Bacteria were eradicated in 91.3% (63/69) of cases treated with the BRL 25000 granules, with only 2 strains of Staphylococcus aureus, 2 of Escherichia coli, 1 of Haemophilus influenzae and 1 of Streptococcus pneumoniae remaining. Eight beta-lactamase producing strains were detected amongst the 49 clinical isolates studied and of these, 6 were eradicated after administration of the BRL 25000 granules. Good clinical efficacy was obtained in 97.8% of cases (89/91), with 1 case of acute tonsillitis and 1 of acute colitis showing no improvement. Adverse reactions were limited to 1 case of vomiting and 3 of diarrhea, and no abnormal laboratory findings were detected.

We compared responses to amoxicillin combined with clavulanic acid (ACA) with a cefaclor regimen in children with skin and soft tissue infections (impetigo and cellulitis) due to Staphylococcus aureus, Streptococcus pyogenes, and Haemophilus species. All isolates from the 41 patients we were able to evaluate were susceptible to ACA by disk susceptibility testing at the onset of treatment. The 21 children receiving ACA and 18 (90%) of 20 taking cefaclor responded to therapy. Clinical cure was achieved in 18 (86%) of 21 and 18 (90%) of 20 in the two groups, respectively. Bacteriological failure occurred in 2 (10%) patients in the cefaclor group and none in the group receiving ACA; however, there were 2 (9%) relapses and 1 (5%) reinfection among the 21 children taking ACA. Adverse effects, although mild, occurred more commonly (9 of 21 versus 1 of 20; P = 0.005) with ACA than with cefaclor.

MIC of cefadroxil (CDX) against A group beta-Streptococcus was distributed between 0.05-0.2 microgram/ml, that is, more susceptible than cephalexin (CEX) an cefaclor (CCL), and susceptible to tetracycline (TC), erythromycin (EM), lincomycin (LCM) resistant strains. Serum level was higher than CCL administered orally at the same dose, and urinary excretion ratio after oral administration was good similarly to CEX and CCL. Patients treated were mostly scarlet fever and upper respiratory tract infections as acute tonsillitis and lacunar tonsillitis. They responded well to CDX at a daily dose of 30 mg/kg divided into 3-4 times. All cases of scarlet fever became normal temperature within 2 days. Among 14 cases in which A group beta-hemolytic Streptococcus was detected by pharyngeal sputum culture at admission, 11 cases became negative on the 1st day. This result was superior to CEX, when this drug was administered orally at a daily dose of 40-60 mg/kg, bacteria became negative at the ratio of 73.3% on the 2nd day. CDX was effective for acute tonsillitis, lacunar tonsillitis, acute bronchitis, impetigo and maxillary lymphadenitis in which numerous A group beta-Streptococcus, Staphylococcus aureus and Haemophilus influenzae were proven, as well as for acute urinary tract infection due to Escherichia coli. Clinical results of CDX in totalling 69 cases were excellent in 63 cases, good in 6 cases, efficacy ratio being 100%. No local nor systemic side effects were observed in 69 cases including maximum 11 days' treatment, as well as no effect was noticed on hepatic and renal functions. From the above results, it was concluded that satisfactory treatment results may be obtained with CDX dry syrup for children at a daily dose of 20-50 mg/kg divided into 3-4 times in acute infections due to CDX susceptible pathogens.

Bacteriological, pharmacokinetic and clinical studies on SY5555 dry syrup (powder which is dissolved before use), a new penem antibiotic for oral use, were performed. The following results were obtained. 1. Antibacterial activities. MICs of SY5555, clavulanic acid/amoxicillin (CVA/AMPC), cefotiam (CTM), cefpodoxime (CPDX), cefaclor (CCL) and cefdinir (CFDN) were determined against clinically isolated Staphylococcus aureus, coagulase negative staphylococci, Streptococcus pneumoniae, Streptococcus pyogenes, Haemophilus influenzae, Moraxella catarrhalis, Escherichia coli and Enterobacter cloacae at a dose of 10(6) CFU/ml. MICs of SY5555 against S. aureus, CNS, S. pneumoniae, S. pyogenes, H. influenzae, M. catarrhalis, E. coli and E. cloacae were 0.2, 0.2, 0.2, < or = 0.025, 0.78, 0.2, 0.78 and 3.13 micrograms/ml, respectively, showing excellent antibacterial effects on these pathogens. Although the effects of SY 5555 against H. influenzae and E. coli were slightly inferior to those of CPDX and CFDN, the drug showed the most excellent antibacterial effect on other strains as compared with the control drugs. 2. Absorption and excretion In this study, plasma concentrations and urinary recovery rates were examined after administration of SY5555 at doses of 5 and 10 mg/kg (potency) after meals. With both 5 and 10 mg/kg doses, peak plasma concentrations were reached 1 hour after administration, at 0.25-2.61 micrograms/ml (mean 1.47 micrograms/ml) and 1.08-2.17 micrograms/ml (mean 1.74 micrograms/ml), respectively. The plasma levels rapidly decreased to 0.06-0.19 micrograms/ml (0.12 micrograms/ml) and 0.0503-0.0637 micrograms/ml) after 6 hours. The half-lives 1.12 hours in the 5 mg/kg group and 1.0 hour in the 10 mg/kg group. The urinary recovery rates were determined in the first 8 hours after administration in the 5 mg/kg and 6 hours in the 10 mg/kg group, and the values were as low as 1.05-12.3% and 1.6-4.33%, respectively. 3. Clinical results The clinical responses were examined in a total of 73 cases including 4 acute pneumonia, 13 acute bronchitis, 11 tonsillitis, 3 pharyngitis, 12 scarlet fever, 2 pertussis, 6 urinary tract infection, 6 otitis media, 7 lymphadenitis, 2 staphylococcal scalded skin syndrome, 2 phlegmon, 4 impetigo and 1 purulent parotitis. The treatment was effective or better in 66 of 70 cases with an efficacy rate of 94.3% (3 undeterminable cases were excluded). Bacteriological effects were examined during the clinical course for detected or suspected pathogens found before administration of SY5555. The effects were determined in 50 cases including 7 cases of polymicrobacterial infections, 57 strains in total. Eight strains, however, persisted, hence the overall eradication rate was 86.0%.(ABSTRACT TRUNCATED AT 400 WORDS)
