Our investigation of cefotiam in pediatric infection produced the following results: 1. Cefotiam was administered intravenously by one shot or drip infusion in 20 patients with infectious diseases. These diseases consisted of 13 pneumonia, 3 upper respiratory tract infections, 3 pyelonephritis, 2 other urinary tract infections and one purulent meningitis. Cefotiam was effective in all cases. 2. Transient elevation in serum GOT, GPT, Al-P and LDH was observed in 3 cases. But other side effect was not noted in any cases.

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.

Fundamental and clinical studies of cefotaxime (CTX) were carried out in pregnant women. The following results were obtained. CTX was more rapidly eliminated from the serum of pregnant women than that of adult males. Urinary excretion of CTX in pregnant women was comparable to that in nonpregnant women and adult males. Passage of CTX to the embryo, fetus and fetal appendages was minimal. Peak amniotic fluid concentration (9.8 mcg/ml) was attained at 3.5 hours after administration of CTX and gradually declined thereafter. This amniotic fluid concentration was sufficiently higher than reported MIC90 of CTX against E. coli strains. CTX was used in the treatment of 6 pregnant patients with acute pyelonephritis and 2 with puerperal infections. The bacteriological and clinical responses were both 100%. Since passage of CX into the amniotic fluid is favorable, CTX can be expected to be effective for the prophylaxis of intrauterine amniotic infection associated with early rupture of the membrane. CTX was used in the treatment of a neonate with purulent meningitis. The clinical response was effective. CTX did not cause any noteworthy adverse reactions or laboratory data abnormalities in our patients or neonates.

From 1976 to 1981, 28 episodes of group B streptococcus (GBS) septicemia were identified in our hospital (CHUV, University Hospital Lausanne), 18 in 17 adults and 10 in newborns. The latter had acute respiratory distress syndrome (8 cases) or meningitis (2 cases). In adults the skin was the main source of infection (6 diabetic foot, 4 acute cellulitis complicating chronic skin diseases, 2 infections secondary to diagnostic procedures (capillary and ascitic taps) and 1 meningitis secondary to neurosurgery). The other sources of infection were 1 pharyngitis, 1 pneumonia and 1 pyelonephritis. Eleven patients had an underlying disease (7 diabetes and 4 malignancies). Four patients developed septic osteoarticular metastases, one after a 3 weeks' course of antibiotic. In the latter case, as well as in the two adult patients who died, the strains of GBS were found to be tolerant to penicillin. Thus, GBS septicemia are not rare in adults and occur often in compromised hosts such as diabetics. The portal of entry is frequently the skin and the course may be severe with distant complications.

In an effort to study whether previous data obtained from animal studies showing decreased blood ketone body concentration and suggesting a shut-off of ketone body production in acute infection are valid also for man, 14 previously healthy patients, suffering from pyelonephritis, pneumonia, serous meningitis or upper respiratory tract infection were investigated. There were great interindividual differences in the ketone body response, which seems to be insulin dependent. The results indicate that in man there is probably no general inhibition of ketone body production in the liver in acute infection.

Laboratory and clinical studies on ceftazidime ( CAZ ), a new cephem antibiotic, were carried out in the field of pediatrics. The results were as follows: Antibacterial activities of CAZ against clinically isolated strains of S. pneumoniae, H. influenzae, E. coli and P. aeruginosa were compared with those of cefotaxime (CTX), ceftizoxime (CZX), latamoxef ( LMOX ), cefoperazone (CPZ) and cefmetazole (CMZ), and also with cefsulodin (CFS) and gentamicin (GM) against P. aeruginosa. Against S. pneumoniae and H. influenzae, CAZ was almost as active as CTX, CZX and CPZ. Against E. coli, it was almost as active as CTX, CZX and LMOX . Against P. aeruginosa, it was almost as active as CFS and GM. Serum concentrations and urinary excretion rates after intravenous bolus injection of CAZ at doses of 20 mg/kg and 10 mg/kg for 5 minutes in each 2 cases (4 cases in total) were determined. The mean serum concentrations of CAZ were 78.9 and 52.0 micrograms/ml at 15 minutes, 38.5 and 27.4 micrograms/ml at 1 hour, and 6.5 and 4.8 micrograms/ml at 4 hours, with serum half-lives (T 1/2) of 1.39 and 1.80 hours respectively. Mean cumulative urinary excretion rate within 6 hours after administration was 84.6%. In a patient with chronic renal failure, serum half-life was 3.22 hours and urinary excretion rate within 6 hours was 22.8% (after intravenous bolus injection of CAZ at a dose of 10 mg/kg). CAZ was administered at a dose of 55.5 mg/kg by intravenous bolus injection to a child with purulent meningitis. The levels of CAZ in the cerebrospinal fluid (CSF) at 1 hour after administration were 2.7-38.9 micrograms/ml with CSF/Serum ratios of 3.2-28.8%. Forty-two pediatric patients with various bacterial infections (pyelonephritis 14, tonsillitis 1, bronchopneumonia 3, pneumonia 17, purulent meningitis 1, bacteremia 2, SSSS 1, enterocolitis 3) were treated with CAZ at a daily dose of 49-222 mg/kg t.i.d. or q.i.d. (as a rule 60 mg/kg t.i.d.). The efficacy rate was 97.6% clinically and 97.8% bacteriologically. No adverse reactions were observed except 1 case with mild diarrhea. Abnormal laboratory findings were also only mild; eosinophilia in 1, slight elevation of GOT in 5 and that of GOT & GPT in 3 cases. These results indicate the usefulness of CAZ in the treatment of bacterial infections in children.

Ceftazidime ( CAZ ), a new injectable cephem antibiotic, was used for treatment of infections in children, and the following results were obtained. After an intravenous injection of CAZ at a dose of 20 mg/kg, the mean blood levels in 2 patients were 41.5 micrograms/ml at 30 minutes, 18.1 micrograms/ml at 2 hours and 2.55 micrograms/ml at 6 hours, with the half-life (T 1/2) of 1.37 hours. In a 22-day-old baby with meningitis given CAZ intravenously at a dose of 43.5 mg/kg, the blood levels were 100 micrograms/ml at 30 minutes, 68 micrograms/ml at 2 hours and 25 micrograms/ml at 6 hours, with the half-life (T 1/2) of 2.96 hours. After intravenous administration of CAZ in doses ranging from 35.7 to 50 mg/kg, CSF concentrations ranged from N.D. to 6.3 micrograms/ml in 3 patients with purulent meningitis, although 19 micrograms/ml at 1 hour and 13 micrograms/ml at 2 hours in 1 patient after intravenous administration of 46.7 mg/kg. In patient with mumps meningitis, CSF concentrations were undetectable after intravenous administration of 35.7 mg/kg. Seventeen patients (each 1 patient with lymphadenitis, tonsillitis and septicemia, each 2 patients with pneumonia, bronchiectatic bronchitis, pyothorax and purulent meningitis, each 3 patients with pyelonephritis and enteritis) were treated with CAZ intravenously, at the daily doses of 178.2 mg/kg and 200 mg/kg in 4 divided doses in patients with meningitis and 44.1 to 103.4 mg/kg in 3 divided doses in patients with other infections (two of them were given by intravenous drip infusion for 30 minutes). The clinical responses were excellent or good in all the patients except for 1 case of Salmonella enteritis (poor) and 1 case of Campylobacter enteritis (poor). The efficacy rate was 88.2%. It was noteworthy that the clinical response was excellent in 1 case of septicemia with P. aeruginosa with leukemic stage of malignant lymphoma and in 2 cases of purulent meningitis. As side effects, fever, eruption, leukocytopenia, elevation in GOT and positive CRP considered to be allergic, were observed on day 16 of administration in 1 case of pyothorax. These symptoms disappeared by discontinuance of administration. In addition, there were elevation in GOT and GPT in 2 cases and elevation in GOT in 2 cases and elevation in GPT in 1 case; they were all mild or transient, and there was nothing to be worried about.(ABSTRACT TRUNCATED AT 400 WORDS)

1. MIC of 6059-S against 92 strains of clinically isolated bacteria were measured. The compound was active against most of Gram-negative rods, but was not active against Staphylococcus aureus. 2. 20 mg/kg of 6059-S (newly synthesized oxacephem antibiotics) was administered to the pediatric patients and its blood concentration was measured by agar well method using E. coli 7437 as a test organism. 3. The mean blood concentrations were maximum at 15 minutes after intravenous one-bolus injection. Maximum levels were 94.5 mcg/ml in the patients of below 5 years old and 98.7 mcg/ml above 6 years old. Their half-life of the blood levels were 95.4 and 110.6 minutes respectively. 4. The mean blood concentrations were highest at the end of the infusion in the cases of 60 minutes drip injection. Maximum levels were 85.0 mcg/ml in the patients of below 5 years old and 64.8 mcg/ml above 6 years old. 5. Clinical efficacy of 6059-S in 6 cases pyelonephritis, 2 cases of sepsis, 1 case of meningitis, 1 case of intraperitoneal abscess, 9 cases pneumonia and 2 case of tonsillitis was 100%. In the case of urinary tract infection, 4 patients were treated successfully by the administration of 20 mg/kg/day of 6059-S. Other bacterial infections were treated with 55 to 200 mg/kg/day. 6. 100% of the causative organisms were eliminated by 6059-S. They were E. coli, Klebsiella pneumoniae, Serratia marcescens, H. influenzae and beta-Streptococcus. 7. No remarkable side effect was noticed during administration.

Aztreonam (SQ 26,776) is the first parenteral monobactam agent to be used in patient trials. The agent has significant activity in vitro against facultative aerobic gram-negative bacteria but not against gram-positive or anaerobic bacteria. Aztreonam was used for a year to treat 106 hospitalized patients with a total of 131 documented gram-negative infections. Important exclusion criteria included granulocytopenia, hyperbilirubinemia, meningitis, patients less than 13 years of age, pregnancy, and history of anaphylaxis to penicillin. In this study of 35 men and 71 women, there were 67 cases of pyelonephritis (25% bacteremic), 19 of pneumonia (16% bacteremic), 10 of skin or soft-tissue infections, 9 cases of osteomyelitis, and 6 cases of postpartum endometritis. During the study period, 159 facultative aerobic gram-negative bacteria were tested for aztreonam susceptibility, and 144 (91%) were found to be susceptible. Eighty percent of infections were cured by both clinical and microbiological criteria and each of the other 26 infections showed clinical improvement. Eradication of the infecting organism was achieved in 89% of infections without adverse reaction or drug toxicity.

The efficacy and safety of intravenous trimethoprim-sulfamethoxazole (TMP-SMZ) were evaluated in 22 adults with serious infections caused by gram-negative bacteria. These infections included pneumonia, meningitis, pyelonephritis, deep-seated abscesses, and endocarditis. Of the 19 patients who could be evaluated, 12 (63%) were cured, and four (21%) showed definite improvement; three patients (16%) failed to respond to treatment. The only serious side effect occurred in a patient who had an acute reaction after his first dose. Mild adverse reactions were relatively common: three patients (13.6%) developed skin rashes, in one case with bronchospasm and eosinophilia. Mild transient decline of renal function was observed in five patients (22.7%) and decline of hepatic function in seven patients (31.8%); these abnormalities were not necessarily attributable to the drug. Although side effects were more common than previous reports indicate, intravenous TMP-SMZ was effective in the treatment of life-threatening infections unresponsive to other antibiotics.
