Cefmenoxime was evaluated in an open trial consisting of 41 patients. Forty infections in 36 patients could be evaluated. Thirteen patients had pyelonephritis due to Escherichia coli (two bacteremic), Pseudomonas aeruginosa, Klebsiella pneumoniae, or Streptococcus faecalis; all improved and 12 of 13 were clinically cured, but one relapse (S. faecalis) occurred at two weeks. Six patients with cystitis due to E. coli, Citrobacter freundii, Serratia marcescens, P. aeruginosa, or S. faecalis all improved, but relapse or reinfection, or both, occurred in five due to P. aeruginosa, S. faecalis, C. fruendii, or E. coli. Neurogenic bladder or other complications were present in five of 13 patients with pyelonephritis and five of six with cystitis. Ten patients with pneumonia and one with tracheobronchitis due to Hemophilus influenzae, S. pneumoniae, S. agalactiae, or Neisseria meningitidis all improved and seven had resolution without relapse, but P. aeruginosa emerged in two patients, one of whom died. Eight soft tissue infections due to Staphylococcus aureus, Peptococcus prevotti, Streptococcus species, or infections of mixed origin resolved in six. Sterility of blood cultures was obtained in one patient with endocarditis due to S. anginosus, but other therapy was substituted. Clinical resolution of the toxic shock syndrome and subsequent negative endocervical cultures for S. aureus occurred in one. Granulocytopenia of unverified cause in four (with less than 1,500 mm3) and two (with less than 2,000 mm3) was reversible. Headache during treatment occurred in six patients and a possible disulfiram-like effect in three. Elevations of serum glutamic oxalacetic transaminase and alkaline phosphatase occurred in five, Coombs' positivity in two, and diarrhea in three. Clinical efficacy of cefmenoxime was significant. Possible side effects require further study.

In this study, 63 patients with various urinary tract infections were treated with cefotaxime in different dosages. They were aged from 10 to 82 years (mean: 59). The cases included 33 cystitis, 25 pyelonephritis, 4 chronic prostatitis and 1 orchiepididymitis. 85 strains of enterobacteria were identified: 20 E. coli, 2 Citrobacter freundi, 5 Proteus mirabilis, 12 indole positive Proteus, 1 Providentia, 11 Klebsiella, 3 Enterobacter cloacae and 31 Serratia marescens and liquefaciens. 80 of these strains had MIC less than or equal to 1 mcg/ml (median: 0,12 mcg/ml). More than 2/3 of the patients were treated with a daily dose of 1.50 to 2 g, and 52 (median: 0.12 mcg/ml). More than 2/3 of the patients results showed 43 cures (9 of these with reinfection) and 20 relapses. Isolated enterobacteria strains were sensitive to cefotaxime in patients with recurrence. Relapses were due to underlying urological pathology. Among reinfection organisms, only one, an Enterobacter cloacae, was resistant to cefotaxime. The clinical, local, systemic and biological tolerance was good. Cefotaxime has been very effective in the treatment of severe urinary tract infections, especially in chronic pyelonephritis and cystitis, at an average daily dose of 2 g.

Fundamental and clinical studies of ceftizoxime, a new cephalosporin antibiotic, in children led to the following results. 1. Ceftizoxime compared favorably with cefazolin (CEZ) and cefmetazole (CMZ) for in vitro activity against clinically isolated strains of Staphylococcus aureus (31 strains), Escherichia coli (29), Klebsiella pneumoniae (30) and Pseudomonas aeruginosa (16). While somewhat less active against S. aureus than CEZ and CMZ, ceftizoxime was far more active than these 2 cephalosporin antibiotics against the test strains of E. coli and K. pneumoniae, which included strains resistant to the 2 drugs. Ceftizoxime was not particularly active against Ps. aeruginosa, but this seeming disadvantage was offset by the absolute ineffectiveness of the 2 reference drugs on this obstinate organism. 2. The time course of mean serum ceftizoxime levels in 3 pediatric patients of 5--10 years old given a single intravenous dose of 20 mg/kg was as follows: 45.4 micrograms/ml at 15 minutes, 40.4 micrograms/ml at 30 minutes, 22.1 micrograms/ml at 1 hour, 10.4 micrograms/ml at 2 hours, 2.9 micrograms/ml at 4 hours and 0.9 microgram/ml at 6 hours. The mean serum half life was 1.12 hours. The mean urinary levels of ceftizoxime at serial 2-hour collection intervals were as follows: 2,477 micrograms/ml for 1--2 hours, 1,235 micrograms/ml for 2--4 hours and 462 micrograms/ml for 4--6 hours. The mean urinary recovery up to 6 hours was 61.0%. 3. The clinical response of 28 children with infection to ceftizoxime treatment was 'excellent' in 22 children, 'good' in 4, and 'poor' in 2. These children comprised 11 with acute pneumonia, 3 with acute bronchitis, 4 with acute pyelonephritis, 2 each with acute purulent arthritis and acute enterocolitis, and 1 each with acute purulent tonsillitis, acute purulent lymphadenitis, furunculosis, subcutaneous abscess, subdural abscess and sepsis. The overall rate of effectiveness was 92.9%. Successfully eradicated strains in the bacteriological sense consisted of 4 strains each of H. influenzae and E. coli, 1 strain each of P. morganii, S. pneumoniae and S. pyogenes, 1 of the 2 strains of S. enteritidis, and 1 of the 3 strains of S. aureus. The overall rate of bacteriological effectiveness was 81.3%. No clinical side effects were observed. Changes in laboratory test findings included slightly and transiently elevated GOT and GPT in 1 child and GOT alone in another child.

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.

Cefotiam, a new broad-spectrum cephalosporin was used for the treatment of 30 cases of urinary-tract infections (UTI). Patients, 20 females, 10 males were between 23 and 76 years old. UTI were 17 cystitis, 9 pyelonephritis and 4 prostatitis. Bacteria isolated from urine were : 24 E. Coli, 3 Proteus mirabilis, 1 Providencia, 3 Klebsiella, 3 Enterobacter, 2 Serratia, 1 Staphylococcus coagulase--, DNAse--. MIC's of cefotiam ranged from 0.003 to 32 micrograms/ml (median MIC : 0.06 microgram/ml). Cefotiam was given intramuscularly in monotherapy, at the daily dosage of 1 and 2 g in two injections during 7 to 28 days. Followup of patients were at least 4 weeks after the end of treatment. Therapeutic results were : 15 cures and 2 failures by relapse in 17 cystitis, 6 cures and 3 failures by relapse in 9 pyelonephritis, 4 cures in 4 prostatitis. General tolerance was excellent in all cases. Intramusculary injections were well tolerated with a 2 p. cent lidocain solution. Biological tolerance and particularly renal tolerance was good in all patients.

In a prospective study, twenty children with a mean age of 4 years were treated with pivmecillinam, 25 mg to 40 mg per kilogram body-weight and day, for acute pyelonephritis. Urine cultures yielded growth of E. coli in sixteen instances, Klebsiella spp. in two, S. saprophyticus in one and a mixed Gram-positive flora in one patient. All children fulfilled the diagnostic criteria for upper urinary tract infection. In all cases where Gram-negative pathogens were responsible, the infections were eradicated. One reinfection was registered in a child with a concomitantly discovered congenital urological malformation. Pivmecillinam also cured one patient infected with S. saprophyticus but was ineffective in the case of mixed Gram-positive flora. It is concluded that pivmecillinam is a valuable new drug for the management of pyelonephritis in children, as most of these infections are caused by Gram-negative organisms.

Amdinocillin in combination with another beta-lactam antibiotic (ampicillin, cephalothin, cefamandole or cefoxitin) was used to treat 25 patients with pyelonephritis (with or without bacteremia), pneumonia, bacteremia secondary to intravenous devices, and urinary tract infections (with catheter in place) due to gram-negative organisms. The combination resulted in a clinical response in 96 percent of the patients and a bacteriologic response in 100 percent at 72 hours. Few toxic effects were seen. At long-term follow-up, relapse occurred in three of 10 patients with pyelonephritis who were treated with a combination regimen and completed their course of antimicrobial therapy with a beta-lactam antibiotic. Reinfection occurred in one patient who had a urinary tract infection with a catheter in place. In vitro testing showed that the cefamandole-amdinocillin combination most frequently produced synergy against the strains of Escherichia coli isolated. Synergy with the antibiotic combinations was also seen against strains of Klebsiella pneumoniae. It was difficult to correlate the in vitro test results with the in vivo therapeutic effect of these antibiotic combinations.

The virulence of 93 clinical isolates of Klebsiella was compared in a mouse model by subcutaneous injection. Skin pathogenicity was measured by estimating the number of viable bacteria in the lesions 24 h after infection with a dose of 10(7) bacteria. Strains of serotypes K1-6 were compared with strains of serotypes higher than K6. All K1 and K5, and some K2 and K4 strains were more virulent for mice than strains with a serotype higher than K6. The K3 strains were significantly less virulent than the strains with a serotype higher than K6. The bacteriological findings were confirmed by histological examination with some strains. No differences in virulence were observed between strains of the same serotype isolated from patients with cystitis or from those with pyelonephritis, nor between strains of the same serotype isolated from the blood of patients with septicaemia or from other sites. The mouse model has been found satisfactory for observing differences in virulence between Klebsiella isolates.

A total of 38 patients with active pyelonephritis and significant bacteriuria were treated with the Bulgarian antibiotic cephalotin, the bacteria isolated from their urine manifesting susceptibility to the Bulgarian broad-spectrum antibiotic cephalotin. Twenty six from the patients were with preserved renal function, and 12 with various stages of renal insufficiency. The subjective complaints, febrility, leukocyturia and bacteriuria were best affected. The highest anti-bacterial effect was observed in the patients with uroinfections caused by E. coli, Proteus mirabilis, Klebsiella and staphylococci. Cephalotin has a good tolerance and has no adverse effects. Painful infiltrations were established in some of the patients in the region of the site of intramuscular application, with a transitory character. Cephalotin was assessed, on the base of the study, to be a good and prospective broad-scpectrum antibiotic, deserving to be widely applied in the therapeutic practice.

Azthreonam, the first monobactam, was given to 40 patients with urinary tract infection. Patients included 27 females, aged 17 to 77 years. UTI was complicated cystitis in 10 patients, pyelonephritis in 11, and prostatitis in 19. The following bacteria were recovered from urine: 12 E. coli, 1 Levinea , 3 Proteus mirabilis, 7 Klebsiella, 14 Serratia and 14 Pseudomonas. MICs of azthreonam ranged from 0.0035 to 16 micrograms/ml (mean 0.12 microgram/ml). Azthreonam was given intramuscularly, as monotherapy, in a daily dosage of 2 g, in two divided doses, for 10 to 29 days (mean: 28 days). Follow-up was at least 4 weeks after completion of treatment. Therapeutic results were as follows: 8 cures and 2 failures by relapse in 10 cystitis , 6 cures and 5 failures by relapse in 11 pyelonephritis , and 12 cures and 7 failures by relapse in 19 prostatitis . General and local tolerance were excellent. There were no hematologic or renal side effects. Transaminases SGOT and especially SGPT increased transiently in 7 patients and returned to normal after treatment was discontinued; premature withdrawal was needed in only one case.
