Twenty-one patients were included in an open randomized study comparing vancomycin 1 g bd with teicoplanin 400 mg daily in severe methicillin-resistant Staphylococcus aureus infections. The median duration of therapy was 15 days for vancomycin and 21 days for teicoplanin. Most patients presented with severe underlying conditions, such as major surgery (8), solid tumours (5), multiple trauma (3). The infections treated, included septicaemia, osteomyelitis, bronchopneumonia, cellulitis and acute pyelonephritis. Mean MICs of the strains were 0.39 mg/l for vancomycin and 0.195 mg/l for teicoplanin. Mean trough and peak serum concentrations of vancomycin were 14.3 +/- 5 mg/l and 34.3 +/- 13 mg/l, while the teicoplanin values were 7.5 +/- 4 mg/l and 17 +/- 7 mg/l. The cure rate was seven of 12 in the teicoplanin group and six of nine in the vancomycin group, with four and three cases, respectively, of improvement and one failure in the teicoplanin group. Transient renal impairment occurred in two cases with both regimens; superinfection and colonization in three patients and one patient, respectively, with both regimens.

One hundred and four children who were hospitalized for documented or suspected non-CNS bacterial infections (56 males/48 females, 22 days to 15 years old) were treated with intravenous imipenem/cilastatin for 9.4 days (range 3 to 28 days). Children up to three years of age received 100 mg/kg/day and older children 60 mg/kg/day, administered in four divided doses. Bacterial pathogens were isolated before therapy in 85%. Diagnoses in the 74 evaluable patients included bronchopneumonia with or without empyema (20%), peritonitis complicating appendicitis (16%), skin/soft tissue abscesses (14%), septicemia (11%) and miscellaneous other infections (39%). Among evaluable patients, 95% were clinically cured or improved. One patients, a marasmic child with pneumonitis due to pseudomonas, died during therapy. One evaluable patient each with shigellosis, Klebsiella pneumoniae empyema and streptococcal pneumonia had bacteriologic eradication or suppression but, due partly to noninfectious complications, had no overall clinical improvement. Most bacterial isolates (101/108) were eradicated, including many gram-negative and gram-positive aerobes and anaerobes; three pathogens persisted (one Proteus mirabilis and one Salmonella typhi, one Staphylococcus aureus); and one Escherichia coli pyelonephritis recurred after therapy ended too early. Imipenem/cilastatin was well tolerated by 91% of children. Clinical adverse experiences (AEs), none serious except for the one death, occurred in 19%; 12% were judged possibly related to imipenem/cilastatin, but none probably or definitely related. No serious laboratory AEs occurred; the most common AEs were eosinophilia (11%), urine discoloration, and infusion site pain. Imipenem/cilastatin is well tolerated and has excellent clinical efficacy in a wide variety of pediatric infections.

Flomoxef (FMOX, 6315-S), a newly synthesized antibiotic which belongs to the oxacephem group, was clinically evaluated for its efficacy and safety in 17 patients with ages ranging from 1 month to 9 year-8-month who had bacterial infections. The results obtained were summarized as follows. 1. A pharmacokinetic study following 20 mg/kg FMOX administration by intravenous bolus injection showed that the half-life of FMOX (beta phase) was 39.8 minutes and the urinary excretion of FMOX in the first 6 hours was 76.5%. 2. FMOX was administered to 3 patients with pneumonia, 8 patients with bronchopneumonia, 2 patients with tonsillitis, 2 patients with pyelonephritis, one patient each with cervical lymphadenitis, and pustulosis associated with severe varicella at daily dosage levels of 61.9 approximately 87.2 mg/kg, divided into 3 or 4 administrations by intravenous bolus injection or by 30 minutes drip infusion. The clinical results of these 17 patients were as follows; excellent: 14 patients, good: 2 patients, poor: 1 patient. The efficacy rate was 94.1%. 3. No clinical adverse reaction was observed in any of the 17 patients. Neutropenia, eosinophilia, a slight elevation of GPT and slight elevations of GOT & GPT were observed in 1, 1, 1, and 2 patients, respectively. No abnormality in coagulation system was observed in any of 10 evaluable patients. 4. MICs of FMOX against 13 strains isolated from patients were as follows. MIC against 2 out of 3 strains of Streptococcus pneumoniae was 0.20 micrograms/ml and that of the remaining 1 strain was 0.39 micrograms/ml.(ABSTRACT TRUNCATED AT 250 WORDS)

Fundamental and clinical studies were performed on a newly developed carbapenem antibiotic, imipenem/cilastatin sodium (MK-0787/MK-0791), and results were summarized as follows. The antibacterial activity of MK-0787 at an inoculum of 10(6) cells/ml against strains of S. aureus which were sensitive or resistant to cefazolin (CEZ), E. coli, P. mirabilis, K. pneumoniae, S. marcescens and P. aeruginosa were determined and compared with activities of ceftazidime (CAZ), CEZ, cefmetazole (CMZ), ceftizoxime (CZX), latamoxef (LMOX), cefamandole (CMD), cefoperazone (CPZ), cefsulodin (CFS) and piperacillin (PIPC). The peak MIC of MK-0787 was less than or equal to 0.024 micrograms/ml against S. aureus, which were sensitive or resistant to CEZ, 0.10 micrograms/ml against E. coli, P. mirabilis, or K. pneumoniae, 0.39 micrograms/ml against S. marcescens and 1.56 micrograms/ml against P. aeruginosa. The antibacterial activity of MK-0787 against these bacteria was, on the whole, superior to that of CAZ, CEZ, CMZ, CZX, LMOX, CMD, CPZ, CFS or PIPC. The pharmacokinetics of MK-0787/MK-0791 was studied in 10 children at dose levels of 10 mg/10 mg/kg and 20 mg/20 mg/kg by a 30-minute intravenous drip infusion. Maximum serum levels of MK-0787, at dose levels of 10 mg/10 mg/kg and 20 mg/20 mg/kg were 41.6 micrograms/ml and 72.9 micrograms/ml, respectively, at the end of infusion and 0.1 micrograms/ml at 6 hours, respectively, after drip infusion. The half-life of both dose levels was 0.9 hour. Mean peak serum levels of MK-0791, at dose levels of 10 mg/10 mg/kg and 20 mg/20 mg/kg, were 49.7 micrograms/ml and 87.0 micrograms/ml, respectively, with half-life of 1.1 and 0.6 hour, respectively. Urinary recovery rates of MK-0787 for 6 hours at dose levels of 10 mg/10 mg/kg and 20 mg/20 mg/kg, were 47.8-82.7% and 25.5-78.0%, respectively, and of MK-0791 for 6 hours were 51.7-93.4% and 40.3-94.4%, respectively. Twenty-four patients, including 1 with purulent meningitis, 1 with septicemia, 1 with pyothorax, 10 with bronchopneumonia, 7 with pyelonephritis and 4 with infections of cutaneous soft tissue were treated with MK-0787/MK-0791 at dose levels of over 100 mg/100 mg/kg/day with purulent meningitis and septicemia and 28.8 mg/28.8 mg-72.8 mg/72.8 mg/kg/day with other infections. The clinical response in all patients was excellent or good.(ABSTRACT TRUNCATED AT 400 WORDS)

Ceftazidime (CAZ) was administered to 34 full-term and premature infants aged 0-27 days with various bacterial infections in a dose of 10 or 20 mg/kg by intravenous bolus injection, and plasma concentrations and urinary recovery rates in these subjects during recovery periods were studied. Because of the small number of the cases recruited, neonates were not divided into the full-term and the premature group, but into 3 groups based on day-age: 0-3 days, 4-7 days, and 8 days or older. Concentrations and rates of transfer of CAZ into cerebrospinal fluid (CSF) were determined in 2 cases, and biliary concentrations in another case. A clinical evaluation of CAZ was performed in 12 male and 6 female infants aged 1 day to 4 months and 19 days, including 2 each with purulent meningitis, pneumonia and pyelonephritis, 3 with septicemia, 1 each with septicemia suspected, cholangitis, osteomyelitis, bronchopneumonia, staphylococcal scaled skin syndrome, and acute enterocolitis and 3 for prophylactic use. Plasma concentrations and urinary recovery rates of CAZ The intravenous bolus injection at 10 mg/kg. Peak plasma concentrations of CAZ were obtained at the first collection (30 minutes) of blood samples or 1 hour in all 3 groups, ranging from 23.3 to 26.9 micrograms/ml with no significant variations, plasma concentrations then slowly decreased, and were still 6.04-9.88 micrograms/ml even at 6 hours after the administration. The half-lives of CAZ in plasma tended to be shorter in older day-age neonates, with mean half-lives being 3.59, 2.50 and 2.50 hours for the youngest. The intravenous bolus injection at 20 mg/kg. Peak concentrations were obtained at the first collection of blood samples in all 3 groups (0-3 days: 15 minutes, the others: 30 minutes), being 54.8, 39.9 and 43.8 micrograms/ml, respectively, then slowly decreased and were still 10.4-15.7 micrograms/ml even at 6 hours after the administration. Inter-age differences in half-lives were marked, i.e., 3.6 hours in 0-3-day group, 3.48 hours in 4-7-day group and 2.75 hours in 8-day or older group. Urinary recovery rates were about 40-60% without reference to day-age neonates. CSF concentrations About 50 mg/kg of CAZ was given to each of 2 cases.(ABSTRACT TRUNCATED AT 400 WORDS)

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.

Ceftizoxime, a new cephalosporin preparation, was evaluated for its antibacterial activity, absorption, excretion and clinical effectiveness, and the following results were obtained. The minimum inhibitory concentrations (MICs) of ceftizoxime against 211 clinical isolates were determined in comparison with those of cefazolin, cefmetazole, cefotiam and 6059 S. Against S. pyogenes (50 strains), ceftizoxime was 1 tube inferior to cefazolin inoculum size of 10(8) cells/ml, but was 2--3 tubes superior to cefmetazole and 6059-S. Against E. coli (50 strains), ceftizoxime and 6059-S were significantly more active than the other drugs. The susceptibility pattern of Klebsiella sp. (50 strains) to ceftizoxime was similar to that to cefotiam and 6059-S. Against Proteus sp. (50 strains), cefotiam and 6059-S were more active than the other drugs. Ceftizoxime was intermediate in activity, and cefazolin was the least active. Against H. influenzae (11 strains), ceftizoxime was the most active, with concentrations of 0.1 mcg/ml required to inhibit 100% of strains with an inoculum size of 10(8) cells/ml and 10(6) cells/ml. A dose of ceftizoxime 10 mg/kg or 20 mg/kg was administered to 15 patients aged from 5 years to 12 years, and serum levels and urinary excretion of the drug were measured. Intravenous bolus injection of the drug in dose of 10 mg/kg and 20 mg/kg yielded mean serum levels of 26.6 mcg/ml and 55.7 mcg/ml at 30 minutes, respectively. The serum levels of the drug, thereafter, declined gradually but still remained 1.3 mcg/ml and 2.7 mcg/ml at 6 hours. The serum half-lives (T 1/2) were estimated to be 1.17 hours in dose of 10 mg/kg and 1.31 hours in dose of 20 mg/kg. When a dose of 20 mg/kg was infused over a period of 30 minutes, the serum levels attained the peak of 72.4 mcg/ml to 82.4 mcg/ml (mean 79.4 mcg/ml) at the end of infusion. The levels, thereafter, tapered to mean levels of 45.3 mcg/ml at 30 minutes, 24.7 mcg/ml at 1 1/2 hours, and 3.6 mcg/ml at 5 1/2 hours, with a T 1/2 of 1.22 hours. Meanwhile, when the same dose was infused over 1 hour, the serum levels attained the peak of 59.4 mcg/ml to 68.5 mcg/ml (mean 64.2 mcg/ml). The mean serum levels after the end of infusion were 41.3 mcg/ml at 30 minutes, 21.6 mcg/ml at 1 hour and 1.9 mcg/ml at 5 hours, with a T 1/2 of 0.97 hours. Urinary recovery of the drug was 69.2% to 79.9% after intravenous injection and 62.3% to 79.9% after drip infusion, most of the given drug was excreted in the first 2 hours after administration. In our clinical study, 27 children with moderate or severe infections (12 cases of bronchopneumonia or bronchitis, 5 of pyelonephritis, 3 of purulent meningitis, etc.) were treated with ceftizoxime at the daily dose of 30--309 mg/kg for 3--23 days. Clinical response was excellent in 10, good in 9, fair in 5 and poor in 3. The drug was proved to be very effective against infections due to H. influenzae K. pneumoniae, E. coli and S. aureus. No serious side effects were observed in any case.

T-1982 (cefbuperazone), a new cephamycin antibiotic, was basically and clinically studied in the field of pediatrics, and the following results were obtained. 1. The antibacterial activity of T-1982 was compared with that of CEZ, CMZ and ABPC. T-1982 was more active than the other drugs against Gram-negative bacteria, the sensitivity of E. coli (22 strains), K. pneumoniae (18 strains), P. mirabilis (19 strains), P. vulgaris (4 strains), P. morganii (5 strains) and K. oxytoca (4 strains) distributing less than 0.39, 0.1, 1.56, 0.39, 6.25 and 0.2 microgram/ml, respectively. Two of 3 strains of C. freundii were inhibited by 12.5 micrograms/ml. Against Gram-positive bacteria, the activity of T-1982 was inferior to that of the other drugs. S. pyogenes (28 strains) were inhibited by 0.78 microgram/ml or less, but the sensitivity of S. aureus (34 strains distributed 12.5-100 micrograms/ml). 2. T-1982 was administered to each 3 children at a dose of 20 mg/kg by one shot intravenous injection or 1 hour drip infusion, or at dose of 40 mg/kg by 1 hour drip infusion. The mean serum levels at 0.25, 0.5, 1, 2, 4 and 6 hours after one shot intravenous injection of 20 mg/kg were respectively 74.3, 56.3, 42.3, 17.6, 5.7 and 1.2 micrograms/ml with the mean half-life of 1.01 hours. The values were 32.9, 50.0, 73.7, 27.5, 12.4 and 4.5 micrograms/ml and 1.31 hours by intravenous drip infusion of 20 mg/kg and 50.4, 104.7, 136.3, 62.3, 18.6 and 6.9 micrograms/ml and 1.16 hours by intravenous drip infusion of 40 mg/kg. The mean urinary recovery rates within 6 hours were 47.7, 67.6 and 60.9%, respectively. 3. Treatment with T-1982 was made in 28 cases of pediatric infections; 1 case of acute bronchitis, 19 cases of acute bronchopneumonia or lobar pneumonia, 2 cases of acute purulent cervical lymphadenitis, 4 cases of acute pyelonephritis and each 1 case of subcutaneous abscess and suspected bacterial endocarditis. The clinical responses assessed in 27 cases were excellent in 21 cases, good in 5 cases and poor in 1 case, the efficacy rate being 96.3%. Bacteriologically, 2 strains of S. aureus, 3 strains of S. pneumoniae, 4 strains of H. influenzae, 2 strains of E. coli and 1 strain of P. mirabilis were eradicated. One strain of S. faecalis was reduced. No side effects were observed in any cases. Slight elevation of GOT and GPT and that of GOT were noted in each 1 case.
