Experimental and clinical studies on cefoperazone (CPZ), a new synthetic cephalosporin, were performed in the field of pediatrics. 1) The MICs of CPZ against 26 strains of S. aureus, 21 strains of E. coli, 20 strains of K. pneumoniae and 15 strains of H. influenzae which were clinically isolated were estimated and compared with those of CEZ and ABPC. Some strains were found to be high in the MIC of CPZ against S. aureus, E. coli and K. pneumoniae by original inoculation but 88% of S. aureus, 95% of E. coli, 95% of K. pneumoniae and 100% of H. influenzae were under 6.25 mcg/ml by 100 times dilution inoculation. The MIC of CPZ against S. aureus was inferior to CEZ and superior to ABPC, and that against E. coli, K. pneumoniae and H. influenzae was superior to CEZ and ABPC. 2) The serum concentration, urinary concentration and recovery rate from urine were measured in two healthy infants and one infant in the stage of convalescence from cholangiohepatitis after a single intravenous administration of 25 mg/kg of CPZ. The mean serum concentration in the two healthy infants was 88.0 mcg/ml at 30 minutes, 63.0 at 1 hour, 31.4 at 2 hours, 12.2 at 4 hours and 4.2 at 6 hours; the half-life was 1.29 hours, and the recovery rate from urine was 14.5%. 3) The clinical effect of CPZ was examined in 16 cases of acute lobar pneumonia or acute bronchopneumonia, 1 case of acute bronchitis and 4 cases of acute urinary tract infections. All of the cases responded effectively or markedly effectively. Among the causative bacteria in those cases, 2 strains of S. pneumoniae, 1 strain of S. faecalis, 1 strain of H. influenzae and 2 strains of E. coli and 1 strain of K. pneumoniae disappeared following the administration of CPZ. The bacteriological effect against 1 strain of P. aeruginosa was unknown, but clinical effectiveness was observed in this case. No clinical side effects were observed. Laboratory examination carried out before and after the administration revealed a rise of GOT and eosinophilia in each one case, but in both abnormality returned to normal after termination of therapy.

Laboratory and clinical studies were performed on 6059-S in the field of pediatrics, a new semi-synthetic 1-oxacephem antibiotic, and results were as follows. 1. MICs of 6059-S were compared with those of cefazolin (CEZ) and cefmetazole (CMZ) on 31 strains of S. aureus, 29 strains of E. coli, 30 strains of K. pneumoniae and 16 strains of P. aeruginosa. With the inoculum size of 10(8) cells/ml an 10(6) cells/ml, the peak of distribution of MICs were S. aureus 6.25, 3.13 micrograms/ml, E. coli 0.2, 0.1 micrograms/ml, K. pneumoniae 0.2, 0.05 micrograms/ml and P. aeruginosa 12.5, 6.25 micrograms/ml, respectively. MICs 6059-S against S. aureus was more less 2 to 3 tubes than CEZ and CMZ, but against E. coli and K. pneunoniae were more higher than 3 to 4 tubes than CEZ and CMZ. 2. The serum concentrations and urinary recovery rate of 6059-S were measured in 5 pediatric patients. 6059-S was given 20 mg/kg by an intravenous injection to 2 cases or a 30 minutes intravenous drip infusion to 3 cases. The mean concentration of the former were 64.3, 44.3, 26.8, 11.7 and 5.0 micrograms/ml at 0.5, 1, 2, 4 and 6 hours, and T 1/2 was 1.51 hours. The urinary recovery rates was 75.0% within 6 hours after the injections. The mean concentration of the latter were 65.3, 86.3, 63.0, 40.3, 17.8 and 8.9 micrograms/ml at 0.25, 0.5, 1, 2, 4 and 6 hours, and T 1/2 was 1.63 hours. The urinary recovery rates was 52.1% within 6 hours after the injection. 3. Eleven cases with acute pneumonia, 1 case with acute bronchitis, 3 cases with acute purulent tonsillitis, 1 case with acute purulent parotitis and 1 case subcutaneous abscess were treated with 6059-S by intravenous injection. All cases were above effective clinically. Five strains of H. influenzae, 3 strains of S. pneumoniae, 2 strains of S. pyogenes and 1 strain of S. aureus were eradicated in all strains. No clinical adverse reaction and abnormal laboratory findings were noted.

Cefotetan (CTT), a new cephamycin antibiotic having a long serum half-life (2.93 +/- 0.78 hours), was evaluated for its safety and efficacy in children. Twenty-four patients were treated with a daily dose of 30 to 100 mg/kg of CTT by intravenous administrations mostly in 2 divided doses. The diagnoses of the effective patients were acute bronchitis (5), pneumonia (4), acute urinary tract infections (4), acute enterocolitis (2), presumed septicemia (1), and phlegmon (1); and the effectiveness was 77.3%. The pathogens recovered from these patients were S. pneumoniae (1), H. influenzae (3), S. marcescens (1), E. coli (2), and K. oxytoca (1). CTT was not effective in staphylococcal pneumonia and empyema (each 1 case), in Pseudomonas pneumonia (2), and in a case of brain abscess and mastoiditis of unknown etiology. Diarrhea (2), and transient elevations of the serum GOT, GPT, and LDH (1) were associated with the CTT therapy, but no severe adverse reaction was encountered. The CSF level of CTT seemed to be lower among several new cephalosporins. From the present study, CTT appears to be a safe and effective antibiotic when used in children with susceptible bacterial infections. A twice-a-day schedule was recommended from its long serum half-life.

Fundamental and clinical studies of cefotetan (CTT) were made in pediatric field and the following results were obtained. Antimicrobial activity MIC80 values of CTT against clinically isolated S. aureus (32 strains), E. coli (33 strains) and K. pneumoniae (33 strains) were 25, 0.1 and 0.1 microgram/ml respectively. Antimicrobial activities of CTT against E. coli and K. pneumoniae were superior to those of CMZ, though the activity against S. aureus was inferior to that of CMZ. Pharmacokinetics When 20 mg/kg of CTT was administered to 3 children, who were 3 to 8 years of age, by a intravenous bolus injection, the mean serum concentrations of the drug after 1/2, 1, 2, 4, 6 and 8 hours were 110.7 +/- 9.2, 81.7 +/- 10.1, 50.0 +/- 7.5, 25.3 +/- 4.6, 14.9 +/- 5.5 and 7.7 +/- 2.8 micrograms/ml respectively, and the mean half-life (beta) was 2.01 +/- 0.32 hours. The mean concentrations of the drug in urine after 0-2, 2-4, 4-6 and 6-8 hours were 1,377 +/- 787, 1,045 +/- 689, 1,067 +/- 680 and 358 +/- 80 micrograms/ml respectively, and the mean recovery rate by 8 hours was 67.3 +/- 16.2%. Clinical study CTT was administered to 42 children of 2 monthes to 14 years of age, and clinical response, bacteriological effect and adverse reaction of the drug were studied. Clinical effects were evaluated in 8 cases of acute purulent tonsillitis, each 1 case of acute otitis media and acute bronchitis, 16 cases of acute bronchopneumonia or acute lobar pneumonia, 9 cases of acute pyelonephritis and 1 case of erysipelas, the results were excellent in 30 cases, good in 3, fair in 2 and poor in 1, and thus 91.7% of efficacy rate was obtained. Out of suspected causative organisms including 12 strains of H. influenzae, 1 strain of H. parainfluenzae, 7 strains of E. coli, 2 strains of S. pyogenes, 2 strains of S. pneumoniae and each 1 strain of S. epidermidis and S. faecalis, all the strains except each 1 strain of H. influenzae and S. faecalis disappeared after the treatment. Thus 92.3% of eradication rate was obtained. No side effects were recognized. Though abnormal laboratory findings were observed in 3 cases (7.1%), including elevation of GOT and GPT in 2 cases and eosinophilia in 1 case, those findings came to be normal after the treatment.

The effect of the endotoxin of a noncapsulated Haemophilus influenzae strain isolated from bronchitis was studied on the respiration of mice. Inhalation of the H. influenzae endotoxin resulted in heavy attacks of dyspnoea with non-specific histological changes in the lung. The endotoxin elicited no direct response in isolated organs, but produced cytotoxic changes in HEp-2 tissue cultures. The experiments led to the conclusion that the clinical signs and the histological changes may be explained by the direct damaging effect of endotoxin on the cells and by the released mediator substances.

Fundamental and clinical studies of ampicillin (ABPC) suppository (KS-R1) were performed in children with respiratory tract infections. Serum levels of ABPC after rectal administration of KS-R1 at a dose of 250 mg (11.4-17.7 mg/kg) in 3 children (3-5 years old) were 4.0-10.2 micrograms/ml (average 6.4 micrograms/ml) at 1/4 hour, 3.8-9.4 micrograms/ml (average 6.2 micrograms/ml) at 1/2 hour, 1.2-4.5 micrograms/ml (average 2.8 micrograms/ml) at 1 hour, 0.3-1.4 micrograms/ml (average 0.7 micrograms/ml) at 2 hours, and 0.3 microgram/ml in 1 case and unmeasurable amount in 2 cases at 4 hours. Urine concentrations of ABPC were 230-445 micrograms/ml (average 312 micrograms/ml) in 0-2 hours, 5.3-156 micrograms/ml (average 66.7 micrograms/ml) in 2-4 hours, and 1.3-13.4 micrograms/ml (average 6.1 micrograms/ml) in 4-6 hours, and the recovery rate into urine was 6.6-27.7% (average 15.6%) up to 6 hours. Clinical effects of KS-R1 on 16 childish patients with respiratory tract infections (acute purulent tonsillitis in 9 cases, acute bronchitis in 5 cases, acute bronchopneumonia in 1 case and acute purulent otitis media in 1 case) were excellent in 13 cases, good in 2 cases and poor in 1 case, and the effective rate was 93.8%. Bacteriologically, 5 strains of S. pyogenes, 4 strains of S. pneumoniae and 3 strains of H. influenzae were all eradicated with eradication rate of 100%. Side effect was weak diarrhea in 1 case, but this diarrhea immediately disappeared with discontinuation of treatment. There was no abnormality of clinical laboratory findings. It was concluded that KS-R1 is a useful drug for the treatment of respiratory tract infections in children.

Cefpiramide (CPM), a new broad-spectrum cephalosporin antibiotic with good antipseudomonas activities, was evaluated for its safety and efficacy in 20 children with bacterial infections. The diagnoses of the patients included pneumonia (10), acute bronchitis (1), streptococcal pharyngitis (1), purulent cervical lymphadenitis (1), urinary tract infections (2), acute enterocolitis (1), infections in agranulocytosis and acute leukemia (2), and acute purulent meningitis (2). Of the 20 patients, 17 were cured by the CPM therapy. The main etiologic pathogens were H. influenzae, P. aeruginosa, P. fluorescens, S. pneumoniae and E. coli. The serum half-life of CPM was 2.4 to 4.1 hours after an intravenous bolus injection. As an adverse reaction, diarrhea was encountered in 4 cases, and 1 of them experienced severe watery diarrhea with significant fecal colonization of K. oxytoca. The data suggest that CPM is an effective antibiotic when used in children with susceptible bacterial infections. Administrations divided in 2 to 3 dosages will be enough to maintain effective serum levels.

In an eight year period 16 cases of serious extrapulmonary Hemophilus influenzae infection in adults were identified, including cases of meningitis, pericarditis, epiglottitis, empyema, cellulitis, osteomyelitis, endometritis, urinary tract infection, orbital cellulitis, primary peritonitis, mesenteric lymphadenitis and aortic graft infection. An 18 month prospective study of H. influenzae infection in hospitalized adults identified 10 cases of bronchitis, 25 of pneumonia and 65 of respiratory tract colonization, but there were no extrapulmonary infections. In 29 percent of the respiratory tract infections, H. influenzae appeared to be a nosocomial pathogen; in 71 percent, the infection was mixed. Finally, 110 clinical isolates of H. influenzae were studied for antimicrobial susceptibility. Eight percent were ampicillin resistant, two strains were resistant to tetracycline and one to chloramphenicol, but all were susceptible to trimethoprim-sulfamethoxazole and cefamandole.

9, 3"-Diacetylmidecamycin (MOM), a new macrolide antibiotic, was administered to 28 patients: 6 with pharyngitis caused by Group A beta-Streptococcus, 2 with lacunar tonsillitis, 8 with upper respiratory tract infection, 6 with acute bronchitis, 3 with Mycoplasma pneumonia, 1 with primary atypical pneumonia, 1 with pneumonia caused by H. influenzae and 1 with whooping cough. MOM in the form of fine granules was administered at a daily dose of about 20-30 mg/kg divided into 3 doses. Isolated group A beta-Streptococcus strains were eradicated in only 1 out of 6 strain S. One strain of H. influenzae was eradicated. The clinical results could be obtained with 21 cases and the response was excellent in 1 case, good in 7, fair in 3 and poor in 10. Although diarrhea was found in 3 cases during the administration of MOM, it was not clear whether these phenomena were caused by MOM, because of the prevalence of diarrhea among the children treated by us at that time.

This study is concerned with the value of bacteriological sputum examination by lower respiratory tract infections. Prominence was given to quantitative aspects; colony forming units and markers of infection as leucocytes, albumin and erythrocytes were determined from homogenized specimens. It turned out that numbers exceeding 10(6) per ml of pathogenic bacteria correlated in more than 90% with clinical evidence of bronchitis or pneumonia if cases with antibiotic treatment are not taken into account. There is, in addition to that, more than 90% correlation between the number of colony forming units of these sizes and a leucocyte count of more than 20 per 125 magnification field, which is significant of infection. The markers of infection mentioned above, can be determined by a simple semi-quantitative test-stick method. It was possible to show good relation between the number of leucocytes counted by microscope and the "Cyturtest". Compared to the "routine method" especially pneumococcus and H. influenzae could be isolated much more frequently by applying the method of homogenizing sputum. The rough quantitative informations of the "routine method" did hardly coincide with the exactly determined bacterial numbers.
