Cefuzonam (L-105, CZON), a new parenteral cephalosporin, was evaluated for its efficacy and safety in 22 children with bacterial infections (Table 1). The results obtained are summarized below. MICs of CZON to 26 strains of isolated organisms are shown in Table 2. MICs to all 14 strains of Haemophilus influenzae and 6 strains of Streptococcus pneumoniae were less than 0.05 microgram/ml. The MIC to 2 strains of Staphylococcus aureus was 0.39 microgram/ml and that to another was 0.78 microgram/ml. Two strains of Escherichia coli showed MICs of less than 0.05 and 0.10 microgram/ml, respectively. The MIC to 1 strain of Enterococcus faecalis was 6.25 micrograms/ml. The CZON was administered in 3 or 4 divided doses at a daily dosage ranging from 58.5 to 85.7 mg/kg by 30-minute drip infusion or intravenous injection to 22 patients (9 cases of pneumonia, 9 cases of tonsillitis, 2 cases of bronchitis, 1 case each of suppurative parotitis and acute pyelonephritis) and the following clinical results were obtained; excellent: 12 cases; good: 7 cases; fair: 3 cases. The overall efficacy rate was 86% (Table 4). Diarrhea was observed in four patients, and was resolved with or without discontinuation of the medication within a week. Anemia was noted in 2 cases. Leucopenia and neutropenia was observed in 1 case. There were a moderate rises in S-GOT and S-GPT activities in 1 patient (Table 4), and they necessitated the cessation of the CZON therapy. The S-GOT and S-GPT activities became normal after the drug treatment was stopped.(ABSTRACT TRUNCATED AT 250 WORDS)

Fundamental and clinical studies on cefuzonam (L-105, CZON), a newly semisynthesized cephem antibiotic, were carried out in the field of pediatrics and the following results were obtained. Antibacterial activities of CZON against clinically isolated strains of Staphylococcus aureus, S. epidermidis, Streptococcus pneumoniae, S. pyogenes, Escherichia coli, Klebsiella pneumoniae, Haemophilus parainfluenzae and H. influenzae were compared with those of cefmenoxime (CMX), latamoxef (LMOX), cefoperazone (CPZ), cefmetazole (CMZ), cefotiam (CTM) and cefazolin (CEZ). CZON was nearly as active as CEZ against S. aureus and S. epidermidis and superior to other antibiotics against other Gram-positive cocci. Against Gram-negative rods, CZON was as active as CMX and superior to other 5 antibiotics compared. Serum concentrations and urinary excretion rates after intravenous bolus injection of CZON at doses of 10 mg/kg, 20 mg/kg and 40 mg/kg for 5 minutes in 1, 5 and 4 cases, respectively, were determined. Mean serum concentrations of CZON at these dose levels were 11.0, 43.8 and 111.5 micrograms/ml at 15 minutes, 2.4, 10.3 and 30.3 micrograms/ml at 1 hour and 0.17, 0.72 and 1.28 micrograms/ml at 4 hours, with serum half-lives of 1.79, 0.88 and 1.19 hours, respectively. Mean cumulative urinary excretion rates within 6 hours after administration were 47.9, 56.3 and 40.3%, respectively. Thirty-four pediatric patients with various bacterial infections (tonsillitis 2, acute bronchitis 1, pneumonia 14, pyothorax 1, sepsis 1, suppurative lymphadenitis 1, UTI 13 and enteritis 1) were treated with CZON at a daily dose of 40-94 mg/kg t.i.d. or q.i.d.. The overall clinical efficacy rate was 94.1%. No adverse reactions were observed except 2 cases with mild diarrhea. Abnormal laboratory findings were also mild; slight elevation of GOT and GPT in 2, eosinophilia in 1 and thrombocytosis in 1. These results clearly indicate the usefulness of CZON in the treatment of bacterial infections in children.

Cefuzonam (L-105, CZON), a new injectable cephalosporin, was used in 12 pediatric patients with infections. The following is a summary of the results: The 12 cases included 3 cases of tonsillitis (pathogen: Haemophilus parainfluenzae in 1 case, Haemophilus influenzae in 2 cases), 4 cases of pneumonia (Staphylococcus aureus in 1 case, pathogen unknown in 3 cases), 2 cases of nephropyelitis (Escherichia coli in 2 cases), 1 case of purulent lymphadenitis (pathogen unknown), 1 case of purulent thyroiditis (mixed infection of Streptococcus milleri, Haemophilus aphrophilus and anaerobes), and 1 case of vulvar abscess (E. coli). Dose levels of CZON were 42.9 approximately 93.3 mg/kg/day divided into 3 or 4 times and the drug was intravenously injected for 6 to 12 days. Clinical efficacies were excellent in 4 cases, good in 5 cases, and poor in 3 cases, with the efficacy rate of 75.0%. The 3 cases with poor efficacy consisted of 1 case each of pneumonia complicated with chronic granulomatosis, purulent thyroiditis associated with piriform recess fistula, and purulent lymphadenitis of armpit developed after surgical operation of congenital heart disease. In the first 2 cases satisfactory efficacy was not obtained by chemotherapy alone, and complete cure was seen after surgical operation. Side effects were not observed clinically. One case each of slight prolongation of prothrombin time and transient elevations of GOT and GPT values were noted but no severe abnormalities were found in laboratory tests.(ABSTRACT TRUNCATED AT 250 WORDS)

Clinical studies were performed on cefuzonam (L-105, CZON), a new cephem antibiotic, as follows. Cerebrospinal fluid (CSF) and serum concentrations. CSF and serum concentrations of CZON were measured in 1 case of septic arthritis without meningitis. One hour after 50 mg/kg intravenous bolus injection, the CSF and serum concentrations were 0.10 and 18.1 micrograms/ml, respectively, and CSF to serum concentration ratio was 0.55%. Clinical efficacy CZON was administered to 15 patients in doses ranging 54.5 approximately 212.4 mg/kg/day (94.1 mg/kg/day on average) t.i.d. or q.i.d. for 4 approximately 12 days (6.5 days on average). Of those patients, 9 were with pneumonia, one each was with bronchitis, with tonsillitis, with septic arthritis, with septicemia, with purulent meningitis and with urinary tract infection. The overall efficacy rate was 100%, i.e., efficacy was excellent in 12, good in 3. Bacteriological efficacy was excellent, i.e., 8 of 8 strains were eradicated. Side effects were observed in 2 cases, i.e., one case with loose stool and another with eruption. Laboratory abnormalities to the drug were not observed during the treatment. The above results suggested that CZON would be a useful antibiotic for treating pediatric bacterial infections.

Studies were carried out on the penetration of cefuzonam (L-105, CZON), a new synthetic cephalosporin antibiotic, into cerebrospinal fluid, and on the clinical efficacy against bacterial infections. The results are summarized as follows: Concentrations of CZON in cerebrospinal fluid at 1 hour after intravenous administration of 100 mg/kg in cases of furunculosis of the external canal, encephalitis and mumps meningitis were 0.56 micrograms/ml, 1.44 micrograms/ml and 0.33 micrograms/ml, respectively. Concentrations of CZON in cerebrospinal fluid at 1 hour after intravenous administration of 100 mg/kg in 3 cases of purulent meningitis were 2.80-6.40 micrograms/ml at the acute stage and 0.56-1.45 micrograms/ml even at the recovering stage. Sensitivities of clinically isolated strains to CZON were determined and expressed as MIC. MICs of CZON on Haemophilus influenzae, Escherichia coli, Proteus mirabilis and Klebsiella pneumoniae were similar to MIC's of cefmenoxime (CMX), and lower than those of cefoperazone (CPZ), cefmetazole (CMZ), cefatiam (CTM) and Cefazolin (CEZ). The MIC of CZON on Staphylococcus aureus was similar to those of CEZ, CMZ and CTM, and lower than those of CMX and CPZ. Clinical responses of CZON were good in 2 cases of purulent meningitis, good in 2 cases of pyothorax, excellent in 1 case of septicemia, excellent in 3 cases of urinary tract infections, excellent in 7 cases and good in 3 cases out of 10 cases of pneumonia. Clinical responses of other diseases were excellent in 4 cases of bronchitis, good in 1 case of furunculosis of the external canal, excellent in 1 case of tonsillitis. No side effects nor abnormal laboratory findings were observed except 2 cases of mild diarrhea out of 24 cases.

Cefuzonam (L-105, CZON) was given intravenously to 20 pediatric patients with the following acute bacterial infections: 13 of bronchopneumonia and 1 each of tonsillitis, purulent cervical lymphadenitis and acute tonsillitis, laryngitis, bronchitis, pyothorax, purulent meningitis complicated with septic arthritis, and urinary tract infection. Good clinical responses were obtained in all of the 20 patients and bacterial eradication of all 16 strains. No side effect was observed except 3 cases of slight elevation of transaminase, and 1 case each of soft stool and eosinophilia. From the above clinical results, it appears that CZON is a useful antibiotic for the treatment of pediatric patients with various kinds of bacterial infections.

The concentration of CZON was determined by HPLC in surgical patients with chronic otitis media, sinusitis, and tonsillitis. One gram of CZON was injected intravenously prior to surgery. The time course of the mean tissue CZON level was as follows: In the middle ear mucosa, 3.7 micrograms/g at 15 min, 7.2 micrograms/g at 30 min, and 2.9 micrograms/g at 1 hr (the half life: 21.3 min). In the maxillary sinus mucosa, 10.5 micrograms/g at 15 min, 11.8 micrograms/g at 30 min, and 2.8 micrograms/g at 1 hr (the half life: 17.5 min). In the tonsils, 14.9 micrograms/g at 15 min, 9.3 micrograms/g at 30 min, and 2.0 micrograms/g at 1 hr (the half life: 13.2 min). The concentration was high in the maxillary sinus mucosa and the tonsils, but was low in the middle ear mucosa. In the formers the transfer ratio reached its peak 15 to 30 min after administration, but in the latter the peak was reached 30 to 60 min after administration. The order of the transfer ratio at each region was above 25%. The tissue concentration exceeded the MIC80s of frequent isolates from these infections. CZON is considered to be a highly useful drug in the treatment of these infections.
