Cefotiam, one of the new cephem antibiotics, was used in 14 cases with pediatric infections: (10 cases with respiratory tract infections, 2 with urinary tract infections, each 1 with purulent meningitis + sepsis and acute appendicitis). The patients were aged between 15 days and 9 years old. The drug was, a rule, given at a daily dose of 50 mg/kg to 100 mg/kg q.i.d. by bolus intravenous injection. The duration of treatment was between 3 and 38 days. The treatment produced the following clinical responses: Out of the 10 cases, good response in 7 with respiratory tract infections, fair in 1 and poor in the remaining 2. The responses in urinary tract infections were excellent in 1 and good in the other case. An apparently clear response was obtained in 1 case with purulent meningitis + sepsis due to K. pneumoniae. Also, an excellent response was seen in 1 case with acute appendicitis. The response rate including fair response was 85.7%. The suspected pathogens isolated from 5 cases (S. aureus: 1. strain, H. influenzae: 1, K. pneumoniae 2, E. coli: 1) were eliminated after CTM administration. Good clinical responses were also obtained in these cases. No side effect was observed. Mild elevation of GOT and GPT was noted during the treatment in 1 case. It is unclear, however, if CTM was associated with this side effect or not. P. aeruginosa, Serratia appeared after superinfection in 1 case.

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.

We examined the antibacterial activity of MX in comparison with those of other CEPs, using aerobic Gram-positive cocci, aerobic Gram-negative bacilli and anaerobic bacteria, 870 strains in total, all isolated from clinical specimens, in 1979 and 1980. Against Streptococcus, CMX showed superior antibacterial activity than those of CFX, CMZ, CXM and CTM. Against H. influenzae, CMX also showed superior antibacterial activity than those of CFX, CMX, CXM, CTM and CEZ. ABPC-and PIPC-resistant strains were sensitive to CMX. CTX, CPZ and CZX also showed antibacterial activities equivalent to that of CMX. Against enteric bacteria, E. coli, Klebsiella, E. cloacae, Serratia, C. freundii and Proteus, CMX showed superior antibacterial activity than those of CFX, CMZ, CXM, CTM and CEZ. Especially, against E. coli, Klebsiella, P. mirabilis, P. rettgeri and P. inconstans, CMX showed strong antibacterial activity. As to non-fermentation bacteria, CMX's antibacterial activity was relatively weak except P. putrefaciens, Alcaligenes and Comamonas. However, it was superior than that of CEZ. In comparison with other CEPs, the strength of CMX varied according to the kinds of bacteria. As to anaerobic bacteria, CMX showed strong antibacterial activity against Peptococcus, Peptostreptococcus, Lactobacillus, Propionibacterium, C. perfringens, Veillonella and Fusobacterium. However, its antibacterial activity against Bacteroides was similar to those of other CEPs.

Clinically isolated 741 strains of 10 bacterial genus (except for Pseudomonas aeruginosa) which are frequent causal pathogens of infection in the otorhinolaryngological field were examined for their sensitivity to second-generation cephem agents, CTM, CXM and CMZ using the first-generation agent, CEZ, as a control. 1) The antibacterial activity of CTM, CXM, and CMZ was expanded to H. influenzae and Proteus spp. (indole positive) as compared with the first-generation agent, CEZ. CTM and CXM and strong antibacterial activity against H. influenzae. CMZ was slightly inferior to them in this activity. In contrast, against Proteus spp. (indole positive) CMZ was most effective and CTM was more effective than CXM. 2) The proportion of strains of S. aureus resistant to CEPs was 6.5% in CEZ, 4.8% in CTM, 8.1% in CXM, and as low as 1.6% in CMZ.

Two hundred seventy-six bacterial strains were isolated as possible causative pathogens mainly from sputum in 248 patients with lower respiratory tract infections at 12 medical institutions in various parts of Japan during the period from September 1982 to March 1983. Of these, 272 isolates including 28 Staphylococcus aureus strains, 38 Streptococcus pneumoniae strains, 107 Haemophilus influenzae strains, 68 Pseudomonas aeruginosa strains, 17 Klebsiella pneumoniae strains, 9 Escherichia coli strains and 5 strains of other species were tested in vitro for MICs of various antibiotics, and their drug sensitivity distributions determined. Data were also analyzed for distribution of cases by clinical entities, age and sex, interrelations between the types of infections and the species and frequency of isolation of organisms, and relations of the antimicrobial regimens at collection of clinical specimens to the species and frequency of isolation of the organisms. It engenders great interest that there was a significant increase in frequency of S. aureus isolation within 7 days after antibiotic therapy, compared to pretreatment isolation frequency, in the 1982 series. This seems to deserve further investigation in detail. The H. influenzae strains isolated with the highest frequency in 1981 and those in 1982 were examined as to susceptibility to several representative antibiotics, with interdrug comparisons: ABPC vs. SBPC, CTM vs. CMZ, and CMX vs. LMOX. The isolates demonstrated high degrees of susceptibility to these drugs and there was no conspicuous change in bacterial sensitivity to the drugs.

Susceptibility of 100 clinical isolates of H. influenzae (84 beta-lactamase non-producing strains and 16 beta-lactamase producing strains) to 5 cephamycin antibiotics was studied in comparison with 3 reference antibiotics. In MIC90 against beta-lactamase non-producing strains, LMOX and ABPC were the most excellent, followed by T-1982, CTT, CTM, CMZ, CFX and CEZ. Against beta-lactamase producing strains, all the cephamycin antibiotics were as active as against beta-lactamase non-producing strains, whereas ABPC was extremely less active with the MIC90 of greater than 100 micrograms/ml. CTM and CEZ were about 1 tube less active than against beta-lactamase non-producing strains. Thus, it was confirmed that the cephamycin antibiotics were stable to beta-lactamase.
