A total of 15 patients with a variety of infectious disease were treated with fosfomycin in Chang Gung Memorial Hospital, Kaoshiung. The drug was administered by iv drip infusion in doses of 204g per day for 5-28 days. The clinical response was satisfactory in 6 (100%) of 6 patients with urinary tract infection, 8 (80%) of 10 with septicemia and 1 with pneumonia. Overall, fosfomycin was effective in 13 (86%) of all patients treated. Except for 1 isolate of the pathogen, B. fragilis, and another 1 isolate of oxacillin-resistant Staphylococcus aureus, all the other 16 pathogens isolated, including Escherichia coli, Aeromonas, Klebsiella. Staphylococcus aureus, Acinetobacter, and Pseudomonas aeruginosa were successfully eradicated. Only 1 case developed skin rash. So fosfomycin is a useful agent and gram (-) organisms including oxacillin-resistant Staphylococcus aureus and Pseudomonas aeruginosa.

Pharmacokinetics and clinical study of aztreonam (AZT) in neonates and premature infants were conducted with the following results: 1. Pharmacokinetics (1) Serum concentrations of AZT at 30 minutes after one-shot intravenous injection of 10 mg/kg and 20 mg/kg to neonates including premature infants were 20.6-26.6 micrograms/ml and 38.5-46.4 micrograms/ml, respectively, and decreased thereafter. A dose response was observed in the serum concentrations with administration of AZT 10 mg/kg and 20 mg/kg. (2) Serum half-lives (T1/2) tended to be shorter in both mature and premature infants as their day-ages increased and T1/2 tended to be prolonged in premature infants compared with mature infants. (3) Changes in serum concentration upon one-hour intravenous drip infusion of AZT 20 mg/kg were very similar to those upon one-shot intravenous injection. (4) Urinary excretions in the first 6 hours after one-shot intravenous injection of AZT 10 mg/kg or 20 mg/kg tended to increase in mature infants as they grew and showed excretion rate of 26.2-54.3% but those in premature infants did not show any specific tendency with rate of 17.5-45.1%. Urinary excretions upon intravenous drip-infusion showed a tendency very similar to those upon intravenous injection. 2. Clinical studies (1) Clinically evaluable cases of AZT treatment were 88 cases (91 diseases), in which pathogenic organisms were identified in 56 cases (Group A), i.e., sepsis 9, purulent meningitis 2, pneumonia 8, urinary tract infection (UTI) 33 and others. Total efficacy rate was 98.2% including "excellent" (39), "good" (16) and "fair" (1). Number of cases in which pathogenic organisms were unknown (Group B) was 11, i.e., suspected sepsis (4), pneumonia (3) and intrauterine infection (4) and the efficacy rate was 100% with "excellent" (4) and "good" (7). Thus, both group A and B showed excellent results. AZT was also given to 24 cases for prophylaxis and all the cases showed prophylactic effect of AZT.4+ Bacteriologically AZT was deemed effective in 53 cases out of 56 (Group A) with identified pathogens "eradicated" and "unchanged" (2), thus the bacterial eradication rate was 96.2%. (3) A minor degree of loose feces was observed in 1 (1.3%) of 80 cases as a side effect. Abnormal laboratory test values found were eosinophilia (3 cases), elevation of GOT and GPT (2), platelet-increase (1), elevation of GOT (1), and thrombocytopenia.elevation of GOT.GPT.LDH (1). Every one of these was of a minor degree and transient. From the above pharmacokinetics and clinical results, standard dosage of AZT to neonates and premature infants should be in a unit dose of 20 mg/kg, twice daily to those with ages between 0 and 3 days, and 2 to 3 times daily to those with ages 4 days and above, by intravenous injection or intravenous drip infusion.

Cefodizime (CDZM), a newly developed injectable cephem antibiotic, was given via bolus intravenous injection at each of 3 dose levels of 10, 20 and 40 mg/kg to each 3 children, and serum and urinary levels and urinary recovery rates were followed. A total of 57 patients received CDZM in the following regimen via bolus intravenous injection, and clinical efficacies, and microbial responses were evaluated. Mean dosage per application: 20.9 mg/kg, number of application per day: between 2 and 4 (2 times for 3 patients, 3 for 26 patients and 4 for 28 patients), mean duration of the therapy: 1 week. Patients consisted of 1 case of peritonsillar abscess, 2 acute bronchitis, 38 pneumonia, 8 urinary tract infection, 1 staphylococcal scalded skin syndrome, 2 cellulitis, 4 purulent lymphadenitis and 1 typhoid fever. In addition to the patients mentioned above 6 patients who dropped out were involved in the evaluation of adverse reactions and influence of the drug on laboratory test data, and the following results were obtained. 1. Five minutes after bolus intravenous injection in doses of 10, 20 and 40 mg/kg, serum levels determined by the bioassay method were at their maxima, i.e. 114.0, 264.6 and 461.6 micrograms/ml, respectively. Serum levels of drugs were dose-dependent throughout all the dosage levels tested. Mean serum half-lives of the drug were 1.757, 1.552 and 1.668 hours, respectively, for the 3 dose levels. Serum levels of the drug determined by the HPLC method were similar to those by the bioassay method: The maximum serum levels occurred at 5 minutes after administration, mean maximum concentrations were 105.5, 264.0 and 461.7 micrograms/ml for the 3 dose levels, and a dose response was noted for the 3 dose levels. The half-lives were 1.755, 1.598 and 1.668 hours, respectively. 2. Mean maximum concentrations in urine determined by bioassay for 2 of 3 cases received 10 mg/kg and 3 cases each given 20 and 40 mg/kg of CDZM were 884.3, 3,061 and 7,352 micrograms/ml, respectively, in the first 2 hours after administration. These levels were also dose-dependent. Mean recovery rates were 74.4, 78.4 and 71.5%, respectively, in the first 8 hours after administration. Mean maximum concentrations in urine measured by HPLC were similar to those determined by bioassay, i.e. 962.3, 3,404 and 7,899 micrograms/ml in the first 2 hours. They were, also, dose-dependent. Mean recovery rates were 82.1, 86.0 and 76.5%, respectively, in the first 8 hours after administration. The HPLC determinations gave slightly higher levels than the bioassay.(ABSTRACT TRUNCATED AT 400 WORDS)

A total of 162 patients (134 males and 28 females) scheduled for coronary artery bypass grafting (144) or valve surgery (18) were randomly assigned to receive, under double-blind conditions, either pefloxacin 400 mg iv or cefazolin 1.0 g 30 min before the surgical incision and then post-operatively 12-hourly x 4 or 6-hourly x 8, respectively. Positive per- and post-operative cultures were seen in 27 patients (11 pefloxacin, 16 cefazolin) and 47 micro-organisms were isolated: 34 per-operatively (21 pefloxacin, 13 cefazolin) and 13 post-operatively (4 pefloxacin, 9 cefazolin). There were five failures of prophylaxis (2 pefloxacin, 3 cefazolin): two early (less than 5 days: 1 pefloxacin, 1 cefazolin) and three late (greater than or equal to 5 days, 1 pefloxacin, 2 cefazolin) divided into (i) one major primary failure in the cefazolin group (1 cefazolin resistant Staphylococcus epidermidis mediastinitis); (ii) two minor primary failures, one in each group (Gram-positive sternal incision abscesses) and (iii) two secondary failures (1 cefazolin resistant Enterobacter cloacae and Pseudomonas aeruginosa UTI in the cefazolin group and one culture negative pneumonia in the pefloxacin group). Tolerance to both antibiotics was excellent. In our sample of patients, the efficacy and safety of pefloxacin was not different from those of cefazolin in prophylaxis in cardiovascular surgery.

We have carried our laboratory and clinical studies on cefodizime (CDZM, THR-221). The results were summarized as follows. CDZM was given by 30-minute drip infusion to 2 children at a single dose of 10 mg/kg and to 2 children at a single dose of 20 mg/kg and to 3 children at a single dose of 40 mg/kg. After the 30-minute drip infusion, mean serum levels of CDZM obtained for the 3 dose levels were 76.16 +/- 5.52 micrograms/ml, 170.49 +/- 16.70 micrograms/ml, 270.01 +/- 50.44 micrograms/ml at the end of injection, respectively, and serum half-lives were 2.03 +/- 0.78 hours, 2.03 +/- 0.38 hours, 2.28 +/- 0.30 hours, respectively. The mean urinary excretion rate of CDZM were 83.3 +/- 22.3%, 73.1 +/- 13.9%, 51.1 +/- 8.5% in the first 8 hours after the 30-minute drip infusion of 10 mg/kg, 20 mg/kg, 40 mg/kg, 40 mg/kg, respectively. Treatment with CDZM was made in 28 cases of pediatric bacterial infections; 5 cases of tonsillitis, 2 cases of bronchitis, 10 cases of pneumonia, 6 cases of enteritis, 3 cases of urinary tract infection and 1 case each of maxillary sinusitis and laryngitis. Results obtained were excellent in 13 cases, good in 7 cases, fair in 2 cases, poor in 6 cases. No significant side effect due to the drug was observed except one case of thrombocytosis and 2 cases each of elevated GOT and elevated GOT and GPT.

From December 1985 to May 1986, Xanthomonas maltophilia (formerly known as Pseudomonas maltophilia) was isolated at an increased rate at our institution; 52 isolates of X. maltophilia were obtained in cultures of clinical specimens from 38 patients during that time. The records of 35 of these patients form the basis of this study. Twelve (71%) of the 17 infected and nine (50%) of the 18 colonized patients had received or were receiving antimicrobial therapy. Eleven of 17 patients (three of seven with septicemia, three of five with pneumonia, three with urinary tract infection, and two with wound infection) responded to antimicrobial therapy. Microbiologic studies of the potential environmental sources revealed growth of X. maltophilia in two water faucets and in one water sample from the medical intensive care unit. X. maltophilia is emerging as an important nosocomial pathogen in immunocompromised patients, especially those receiving broad-spectrum antimicrobial therapy.

Cefoperazone was used in the treatment of infections in 13 cases of chronic renal failure. In 8 cases recurrent urinary tract infections were diagnosed, septicaemia in 3 cases, pneumonia in 2. Cefoperazone 2-4 g daily was a very effective and well tolerated drug. Only one therapeutic failure was noted in a patient with mixed urinary tract infection (strains of Enterobacter cloacae and Klebsiella pneumoniae). No side effects developed, and in patients in the phase of moderate renal failure some decrease of serum creatinine was noted after the completion of treatment.

Patients under immunosuppressive therapy with malignant diseases, malformations, premature infants or children after major surgical interventions and trauma are particularly susceptible to infections. In these patients nosocomial infections with multiply resistant organisms may occur despite broad spectrum antibiotic prophylaxis or antimicrobial chemotherapy of existing infections. In an open clinical study 31 infants and children with an overall 45 episodes of life-threatening hospital-acquired infections occurring under broad spectrum antimicrobial coverage were treated with imipenem/cilastatin alone or in various combinations. All the patients were immunocompromised. The most frequent single diagnosis was sepsis--documented by a positive blood culture--followed by nosocomial pneumonia, urinary tract infection and peritonitis. In seven patients an infection of implanted biomaterial was present which could not be controlled by the previously administered antimicrobial therapy. Imipenem/cilastatin was given in a dose of 50 mg/kg BW. Therapy was well tolerated, no side effects were observed. A total of 34 of 45 episodes could be successfully treated with imipenem/cilastatin alone or in various combinations. One child died from refractory candida sepsis; five further children died from the underlying disorder, the respective infectious complications having been controlled adequately. Treatment failures were due to infection with Candida albicans, Pseudomonas cepacia and resistant Streptococcus faecium. Imipenem/cilastatin proved to be a suitable antibiotic for the treatment of life-threatening nosocomial infections and reinfections in children.

Pharmacokinetic, bacteriological and clinical studies on cefdinir (CFDN), a newly developed oral cephalosporin, were performed on children with infections. The pharmacokinetics was examined in 3 patients. The peak plasma concentrations were 1.97 micrograms/ml, 0.84 microgram/ml and 1.67 micrograms/ml in the 3 patients. The 0 to 6 or 8-hour urinary excretion rates were 22.2%, 18.1%, and 32.7%, respectively. These results were similar to those in adult patients. Clinical response to CFDN was evaluated in 21 patients, 4 patients with pharyngitis (an efficacy rate of 100%), 7 with tonsillitis (85.7%), 1 with bronchitis (excellent), 1 with pneumonia (fair), 6 with scarlet fever (100%), 1 with staphylococcal scaled skin syndrome (good) and 1 with urinary tract infection (good). Thus, an overall efficacy rate of 90.5% was achieved. With regard to microbiological effect on pathogens, 14 of the 15 strains identified as pathogens were eradicated, with an eradication rate of 93.3%. The safety was evaluated in a total of 23 cases. Diarrhea, elevated eosinophil count and elevated S-GPT were observed in one patient each. The side effect and abnormalities in laboratory tests were not serious, however. It was concluded that CFDN, with its excellent antibacterial effect, was an efficacious and safe drug for the treatment of pediatric infections.

We randomized 400 patients who were scheduled for an elective cardiovascular operation involving median sternotomy to receive cefamandole nafate or cefonicid in a prospective double-blind study. Three hundred fifty-seven patients were evaluable for prophylactic efficacy. Chest wound and donor site infections and early prosthetic valve endocarditis occurred more frequently with cefonicid (11 patients, 6.3%) than with cefamandole (4 patients, 2.2%) (p = 0.05). Three patients, all in the cefonicid group, required sternal debridement to control postoperative deep wound infections. Twenty-five miscellaneous postoperative infections (urinary tract infection, pneumonia, intravenous site infection, bacteremia, sepsis, Clostridium difficile diarrhea) occurred in 16 patients (9.19%) in the cefonicid group and four in 4 patients (2.19%) in the cefamandole group (p = 0.003). These data indicate that cefamandole is superior to cefonicid in preventing both surgical wound infections and miscellaneous nonsurgical infections after cardiovascular operations.
