Fundamental and clinical trials were carried out with cefminox (CMNX, MT-141) in pediatric infections. Results were as follows. The mean serum concentrations of CMNX following intravenous injection of 10, 20 and 40 mg/kg were 73.1, 112.5 and 181.4 micrograms/ml at 15 minutes after injection, respectively. The serum half-life times were 1.37, 1.20 and 1.53 hours, respectively. Average recovery rates in the urine until 6 hours from the start of injection were 91.4, 59.4 and 85.8%, respectively. The antimicrobial activity of CMNX against clinically isolated organisms was measured; CMNX was more active than CMZ and CEZ against H. influenzae. CMNX was equal to or more active than CMZ and CEZ against E. coli. CMNX was administered clinically to 32 pediatric patients with various infections; 19-pneumonia, 5-bronchopneumonia, 3-bronchitis and 5-pyelonephritis. Overall efficacy rate was 93.8%. Slight elevation of S-GOT and S-GPT was observed in 2 patients. No other serious side effect was observed.

Studies on the antibacterial activity, absorption and excretion and also clinical investigation in the field of pediatrics have been carried out with cefotiam (SCE-963, CTM), a new cephalosporin antibiotic. 1) The MICs of CTM against the following clinical isolates were measured and compared with those of CEZ: S. aureus (81 strains), E. coli (27) and K. pneumoniae (27), with CTM being inferior by 1 tube in S. aureus, being superior by 2 to 3 tubes in E. coli and by about 2 - 3 tubes in K. pneumoniae. 2) Absorption and excretion. After intravenous one shot injection at dose levels of 10 mg/kg and 20 mg/kg, the peak in the serum concentration was shown in the 15-minute value with 18.1 and 36.6 mcg/ml for 10 mg/kg and 20 mg/kg, respectively. The half-life in ;the serum was 1.14 and 0.61 hours, respectively. In the case of 1-hour intravenous drip infusion at a dose level of 10 mg/kg, it was 14.3 mcg/ml, with 0.98-hour half-life in the serum. The recovery rates from the urine within 0 to 6 hours were 50.6% and 66.2% in the case of intravenous one shot injection at dose levels of 10 mg/kg and 20 mg/kg, respectively, with 71.1% in the case of the 1-hour intravenous drip infusion. 3) Two to 3 hours after intravenous one shot injection of CTM in H. influenzae-meningitis every 4 hours at a dose level of 62.5 mg/kg at one time, the cerebrospinal fluid concentration of CTM was only 2.12 to 10.0 mcg/ml, and this fact suggests that CTM is a useful cephalosporin for treating purulent meningitis. 4) CTM was administered in 19 clinical cases, with the results being: excellent in 4 out of 4 cases of bronchitis; excellent in 5 and good in 1 out of 6 cases of pneumonia; excellent in 3 cases of pyelitis; good in purulent parotitis, purulent meningitis and bacterial pericarditis; and excellent in peritonsillar abscess, purulent osteomyelitis and staphylococcal scalded skin syndrome (S.S.S.S.). No side effects have been observed in all cases. As for abnormal laboratory findings, 3 cases of eosinophilia were seen.

The authors have carried out the laboratory and clinical studies of ceftizoxime (CZX), and obtained the following results. 1. The antibacterial activities of CZX were measured by plate dilution method against clinical isolates of S. aureus, E. coli, K. pneumoniae and P. aeruginosa. CZX inhibited the growth of S. aureus at concentrations less than 12.5 micrograms/ml, and the peak of sensitivity distribution was obtained at 3.13 micrograms/ml with an inoculum size of 10(6) cells/ml. And the peak sensitivity distribution of E. coli and K. pneumoniae were obtained at less than 0.1 microgram/ml and that of P. aeruginosa was obtained at 6.25 micrograms/ml. 2. Phagocytosis was determined by Quie's method. Phagocytosis of E. coli and K. pneumoniae by human polymorphonuclear neutrophil was more enhanced in the presence of 1 MIC and 1/2 MIC of CZX than of CEZ at 4 and 6 hours after incubation. 3. As for pharmacokinetic study, CZX was given by intravenous injection and drip infusion for 1 hour at a single dose of 10 mg/kg and 30 mg/kg. After intravenous injection of 10 mg/kg and 30 mg/kg of CZX, the mean peak serum levels were 19.1 +/- 3.4 micrograms/ml and 69.1 micrograms/ml at 30 minutes, and half-life times were 1.20 hours and 1.35 hours, respectively. After 1 hour drip infusion of 10 mg/kg and 30 mg/kg of CZX, the mean peak serum levels were 28.8 +/- 3.6 micrograms/ml and 60.9 +/- 5.9 micrograms/ml at the end of infusion, and half-life times were 1.40 hours and 1.77 hours, respectively. The mean urinary excretion rates were between 75.3% and 101% up to 6 hours after intravenous injection and drip infusion. 4. CZX was given to 4 cases with tonsillitis, 3 with pneumonia, 1 with enteritis, 4 with U.T.I., totaling 21 cases. A daily dose of CZX between 350 mg and 2,000 mg was given for 3 to 5 days. Clinical results obtained were good in all cases. No side effects and abnormal laboratory findings were observed.

Cefmetazole (CMZ), an antibiotic agent of the cephamycin group, is resistant to beta-lactamase and has a broad antibacterial spectrum covering Gram-positive cocci and Gram-negative bacilli. However, it has not been indicated for Gram-positive cocci. We examined its clinical, bacteriological and side effects in 2 infants with pneumonia and 2 with pyothorax, which had been suggested to be caused by CEZ-resistant and CMZ-sensitive Staphylococcus aureus or other inflammatory organisms by a disc sensitivity test, for 2 years and 3 months from January, 1981 to March, 1983. The patients aged 1 to 22 months, and a mean daily dose of 108 to 115 mg/kg was divided into 2 to 4 equal doses and injected into the vein at one shot for a mean fo 19 days. The following results were obtained: The clinical effect of CMZ was evaluated to be good in 1 and fair in 1 of 2 infants with pneumonia, and excellent in 1 and good in 1 of 2 with pyothorax. Bacteriologically, S. aureus was removed in an infant with pneumonia and in 2 with pyothorax. Bacteriological test was not conducted in the remaining 1 with pneumonia. No side effects were found in any cases. Eosinophilia appeared as an abnormal clinical test value in a case, but the number of eosinophils became normal after termination of the medication. As mentioned above, CMZ manifested an excellent clinical effect in infants with pneumonia or pyothorax caused by S. aureus although the number of the patients was small. From the results the antibiotic agent can be expected to be effective in these disease.

1. The in vitro antibacterial activity of cefoxitin was nearly equal to that of CEZ and CET against the 6 species of clinically isolated strains. Cefoxitin, furthermore, had an antibacterial activity against the strains of P. morganii resistant to CEZ and CET. 2. Cefoxitin was applied to a total of 17 patients including 6 cases of bronchitis, 5 of pneumonia, 2 of enteritis, and 1 each of pharyngitis, laryngitis, sinusitis and lymphadenitis. The results showed an efficacy rate of 88%. In the 6 patients from whom the isolation of pathogenic organisms was possible, the bacteriological response to cefoxitin was appreciable the efficacy rate being 83%. Thus, it is considered that cefoxitin also has a significant antibacterial activity in vivo. 3. As to the side effects following the administration of cefoxitin, urticaria-like eruption was observed in 1 case, and an elevation of transaminase in another. These findings, however, became normal soon after discontinuation of cefoxitin treatment.

The current state of causative bacteria in infectious diseases and the trends in resistance to antimicrobial agents were mentioned. The commonest micro-organisms isolated from the blood and intravascular catheter tips were CNS, S. aureus and C. albicans. Significant urine culture isolates were E. coli and other enterobacteriaceae in uncomplicated UTI, and Enterococcus spp. and Pseudomonas spp. in complicated UTI with a urinary catheter. In respiratory tract infections (RTIs), H. influenzae, S. pneumoniae, B. catarrhalis, S. aureus and P. aeruginosa, were common causative organisms. Community-acquired pneumonia was mainly caused by H. influenzae, S. pneumoniae and B. catarrhalis. In common with hospital-acquired pneumonia, P. aeruginosa, S. aureus and enterobacteriaceae were the frequent microorganisms isolated. In anaerobic infections, the most common micro-organisms were B. fragilis and other B. fragilis group isolated from intra-abdominal focus of post operative patients. The trends in the antimicrobial susceptibility of isolates of common bacteria over a period of 5 years (1988-1992) have been monitored. The proportion of isolates of S. aureus resistant to CEZ, CMZ, FMOX, IPM or MINO has increased. There was no trend towards increased resistance among isolates of P. aeruginosa except for CBPC. The incidence of resistance to PCG, ABPC, EM and LMOX increased in isolates of S. pneumoniae and that of resistance to PIPC, CMZ, LMOX and IPM increased in those of B. fragilis group.

An epidemiological investigation for penicillin-resistant Streptococcus pneumonia (PRSP) was performed at 18 medical institutes in Kinki area by the questionnaire from Kinki Infection Working Group 1995. This investigation was the first report that was performed for a long term (one year) and a large area. The most frequent specimen was sputum from out-patients (50.3%) and inpatients (48.8%), and especially from spinal fluid of 3 cases were detected. Polymicrobial infection with more than 3 pathogens was 15.7%, and it was more frequent than MRSA previously investigated. Simultaneous pathogens detected with PRSP were Candida species, Haemophilus influenzae and Staphylococcus aureus. In terms of chemosusceptibility, VCM (100%), FMOX (97.9%), IPM/CS (85.9%), CEZ (93.4%) and CDTR-PI were determined to be high by sensitive. However, the sensitivity of CCL, which was one of the most common antibiotics, was only 37.7%.
