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.

Experimental pyelonephritis induced in rats by a single intrarenal injection of Pseudomonas aeruginosa, Serratia marcescens, Candida albicans, and Cryptococcus neoformans was studied pathologically and immunohistologically. The lesions which develop following intrarenal inoculation were similar to those seen during the course of pyelonephritis in man. Localization of the whole bacteria and the amorphous bacterial antigens and the whole fungi and the amorphous fungal antigens in the inflammatory lesions persisted up to 10-12 and 6-8 weeks, respectively. After that, continued inflammatory changes in progressive scarring can evolve in the absence of persistent bacterial or fungal antigens. Rat gamma globulin was localized in the plasma cells of the renal inflammatory infiltrates from 5-6 days to the end of the experiment (14th week). The incidence of progressive renal sclerosis was high in case of Candida pyelonephritis. The possible roles of progressive renal scarring by C. albicans are discussed.

Bacterial pyelonephritis was induced in mice by direct microinoculation of Pseudomonas aeruginosa in the kidney. In the acute phase of P. aeruginosa pyelonephritis, a state of cell-mediated immunity impairment, evaluated both in vitro as lymphocyte reactivity to concanavalin A and in vivo as host versus graft reaction has been observed. Furthermore, delayed-type hypersensitivity to specific bacterial antigen has been detected only when the kidney infection was subsiding, i.e., 3 weeks after bacteria inoculation. When investigating the mechanism of such T-cell impairment, we were unable to transfer the immunodepression, suggesting that suppressor cells are not involved in vivo. The role of P. aeruginosa inhibition of cell-mediated immunity in the pyelonephritic host is discussed.

The incidence of infection in the renal transplant patient is directly related to the net immunosuppressive effect achieved and the duration of time over which this therapy is administered. A second major factor in the causation of infections in this population is the nosocomial hazards to which these patients are exposed, ranging from invasive instrumentation to environmental contamination with Aspergillus species, Legionella pneumophila, Pseudomonas aeruginosa and other microbial pathogens. Careful surveillance is necessary to identify and eliminate such nosocomial sources of infection. The major types of infection observed can be categorized according to the time period post-transplant in which they occur: postsurgical bacterial infection in the first month after transplantation; opportunistic infection, with cytomegalovirus playing a major role, and transplant pyelonephritis in the period one to four months post-transplant; and a mixture of conventional and opportunistic infections in the last post-transplant period. Conventional infection in this late period occurs primarily in patients with good renal function who are receiving minimal immunosuppressive therapy; opportunistic infection occurs primarily in patients with poor renal function who are receiving higher levels of immunosuppression.

Ceftizoxime (FK 749, CZX) was evaluated in 24 children with a suspicion of bacterial infection. Of the 17 confirmed bacterial infections, 16 were shown to be effective (effective rate, 94.1%). The diagnosis included acute pharyngitis (2), pneumonia (6), staphylococcal empyema (1), cervical purulent lymphadenitis (2), acute enterocolitis (2), acute pyelonephritis (1), SSSS (1) and suspected septicemia (2). The etiological pathogens recovered were Streptococcus anginosus (1), Streptococcus pneumoniae (1), Staphylococcus aureus (2), Haemophilus influenzae (3), enteropathogenic Escherichia coli (1) etc. A case of suspected Pseudomonas aeruginosa septicemia was not effectively treated with CZX. The serum half-life of CZX was 1.36 hours after intravenous bolus infection. A cerebrospinal fluid level of CZX was 6.2 mcg/ml 1 hour after intravenous bolus injection of 1 g (23.8 mg/kg) in a child with inflamed meninges. No severe adverse reaction was encountered with the CZX therapy. The data suggest that CZX is an excellent candidate for the first choice parenteral antibiotic in the pediatric infections.

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.

In 54 patients suffering from a variety of severe systemic infections the combination of mezlocillin (4 g iv 6-hourly) plus cefotaxime (2 g iv 8-hourly) was compared to that of gentamicin (1.5 mg/kg im or iv 8-hourly) plus cefoxitin (2 g iv 6-hourly). In the gentamicin/cefoxitin group metronidazole (500 mg iv 8-hourly) was added for anaerobic infections. Treatment assignment was randomized. The patients' diagnoses were: pyelonephritis (24), pneumonia (14), infected burns (9), osteomyelitis (2), and abdominal infections (5). Pathogens included: Escherichia coli (31), other Enterobacteriaceae (21), Pseudomonas aeruginosa (13), anaerobes (4), and others (2). Treatment with mezlocillin/cefotaxime cured 20 (74%) of 27 patients and caused improvement in 5, while in 19 (70%) patients the pathogens were eradicated. In the gentamicin/cefoxitin group 17 (63%) of 27 patients were cured and 6 improved, while in 15 (56%) pathogens were eradicated. One patient in the first group developed a rash, while in the second group two patients developed thrombophlebitis and another two transient nephrotoxicity. The combination of mezlocillin and cefotaxime can be recommended for the rational and empirical treatment of serious systemic infections.

Ceftazidime, a new beta-lactamase resistant aminothiazo-oyl cephalosporin with a broad spectrum of antibacterial activity against gram-positive and gram-negative bacteria, including Pseudomonas species, was evaluated clinically for efficacy and safety at 3 dosage levels in patients with acute genitourinary tract infection. Sixty patients with infections, including cystitis, pyelonephritis, epididymitis and prostatitis, were assigned randomly to 1 of the 3 dosage regimens: 250, 500 or 1,000 mg. administered intramuscularly every 12 hours. Patients were evaluated bacteriologically and clinically during the course of treatment and after treatment. All patients became asymptomatic and showed clinical improvement or cure within 48 to 72 hours regardless of dosage. Bacteriological success, namely eradication of the pathogen during therapy with no recurrence of superinfection during followup, was attained in 95 per cent of the patients with uncomplicated infections and in 61 per cent of those with complicated infections. Superinfections accounted for most of the noncures, particularly with the 250 mg. regimen. The difference in success rates between the 250 mg. dosage, and the 500 mg. and 1 gm. dosages in patients with complicated infections was statistically significant. Injections were well tolerated without significant side effects. No clinically important variations in laboratory tests were observed. The results indicate that ceftazidime is a useful third generation cephalosporin for complicated and uncomplicated genitourinary infections but it is recommended that the 250 mg. dosage not be used in patients with complicated infections.

Twenty-one hospitalized patients with infectious diseases were randomly assigned to receive either thienamycin formamidine/renal dipeptidase inhibitor or cefazolin. Infections treated included septicaemia, pneumonia, osteomyelitis, pyelonephritis, cellulitis and cutaneous abscesses. All eleven patients treated with thienamycin formamidine/renal dipeptidase inhibitor responded well to therapy. One of the ten patients treated with cefazolin developed a superinfection with Pseudomonas aeruginosa. Side effects detected were minor in both groups.

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.
