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.

The clinical manifestations of septicemic melioidosis and other bacterial septicemia were studied at Srinagarind Hospital, Khon Kaen University. Forty-three cases of septicemic melioidosis and 68 non-melioidosis septicemia cases were analysed. By univariate analysis, the following clinical features are associated with septicemic melioidosis: male patients; age below 45 years; underlying diabetes mellitus or renal failure; pulmonary infection, impending respiratory failure and multiorgan involvement, while abdominal pain and urinary tract infection were more common in non-melioidosis septicemia. By using discriminant analysis and logistic regression, 3 features (diabetes mellitus, multiorgan involvement, and no abdominal pain or pulmonary infection) could discriminate the two groups with the accuracy of more than 85 per cent.

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.

A 77-year-old male, who had been treated with carboquone and busulfan for polycythemia vera (PV), developed myelodysplastic syndrome (MDS) 8 years later. On admission the peripheral blood revealed pancytopenia, but blastoid cells were not noted. The bone marrow showed hypercellularity, and functional and morphological abnormalities in trilineages of hemocytes. Cytogenetic study showed complex abnormalities involving chromosomes 5 and 7. We diagnosed this case as secondary MDS to alkylating agents. He was treated with 1, 25 (OH)2 vitamin D3. However, it was not effective and the percentage of myeloblasts increased to 14.4%. In spite of supportive therapy, he died of sepsis due to urinary tract infection.

A retrospective study was performed of 292 infants younger than 2 months of age with a history of fever who received a standardized evaluation and were admitted to the hospital for possible sepsis. The purpose was to correlate the presence of this symptom with subsequent temperature patterns and the rate of serious bacterial infections (SBI). Caretakers reported fever per rectum via thermometer in 244 infants and tactile fever in 48 infants. Of 244 infants with reported fever per rectum, 224 (92%) had fever on presentation or during the subsequent 48 hours of hospitalization; by contrast, only 22 of 48 infants (46%) with reported tactile fever had fever on presentation or during the subsequent 48 hours of hospitalization (P less than 0.0001). Of 26 infants with tactile fever who were afebrile on presentation, none had subsequent fever during hospitalization and only 1 (3.8%) had SBI (urinary tract infection); of 40 infants with reported fever per rectum who were afebrile on presentation, 8 (20%) had subsequent fever during hospitalization and 4 (10%) had SBI (meningitis, bacteremia, osteomyelitis and urinary tract infection). There were a total of 19 infants (6.5%) with SBI; although 5 (27%) were afebrile on presentation (4 with reported fever per rectum, 1 with tactile fever), all 19 exhibited abnormal clinical and/or laboratory features on evaluation which were suggestive of underlying serious infection. Management decisions for young infants with reported fever should be based on both clinical findings and temperature-pattern profiles.

The effect of intravesically applied antibiotic solution in the prevention of infectious complications of renal transplantation was evaluated in a prospective, randomized study. The bladder was filled preoperatively with saline solution containing cephalotin in the test group, and with saline solution only in the controls. Both groups of patients received IV doses of cephamandole during, and once after, surgery. Two hundred consecutive patients were randomly allocated to the study groups. The overall incidence of urinary tract infection was 10.4% during the first 4 postoperative weeks; that of wound infections was 1.6% and of septicemia 3.3%. The addition of cephalotin to the bladder irrigation fluid did not have any effect on the overall incidence of infectious complications.

Nine neonates were treated with aztreonam (AZT) and its clinical efficacy and side effects were evaluated. Six of the patients were treated with a combination of AZT and ampicillin. Ages of the patients ranged from 0 to 24 days, and their body weights ranged from 2,290 to 4,260 g. Doses of AZT ranged 18.8 to 23.7 mg/kg every 8 to 12 hours for 3 to 7 days. Three patients with infections including urinary tract infection, cervical abscess, and suspicion of sepsis, appeared to respond to the treatment of AZT alone. Among them, clinical results were excellent in 1, good in 2 patients. Those patients subjected to the combination therapy showed excellent response in 1 and good in 5. The drug was well tolerated, but 1 had diarrhea. The pharmacokinetics of AZT was studied in 9 patients. Their ages ranged from 0 to 30 days, and body weights ranged from 2,000 to 4,000 g. Serum concentrations of AZT were 27.2 to 48.3 micrograms/ml at 1 hour after single 20 mg/kg intravenous bolus injection, and the levels were 3.4 to 15.5 micrograms/ml at 6 hours in 5 infants heavier than 2,500 g. Elimination half-lives of AZT ranged from 1.57 to 3.72 hours (mean 2.72 hours). Serum concentrations of AZT were 21.6 to 41.8 micrograms/ml at 1 hour after single 20 mg/kg intravenous bolus injection, and the levels were 10.2 to 17.0 micrograms/ml at 6 hours in 3 infants lighter than 2,500 g. The elimination half-lives of AZT were 3.63 to 4.86 hours (mean 4.31 hours).(ABSTRACT TRUNCATED AT 250 WORDS)

Clinical and pharmacokinetic studies on aztreonam (AZT) were performed in neonates. The results are summarized as follows: A total of 6 cases consisting of 5 mature and 1 low-birth-weight infants was clinically evaluated. AZT 20 mg/kg was administered 2-3 times daily, via 1 hour intravenous drip infusion for 6-21 days. Concomitantly, vancomycin (VCM) 15 mg/kg was administered to 1 case 3 times daily, via 1 hour intravenous drip infusion for 3 days and ampicillin (ABPC) 20-50 mg/kg to 3 cases 3 time daily via 30 minutes intravenous drip infusion for 2-6 days. Of the 6 bacterial infection cases (1 with sepsis and purulent meningitis, 2 with sepsis, 2 with urinary tract infection and 1 with perirectal abscess), clinical effects of AZT were evaluated in 4 cases (2 each with sepsis and urinary tract infection) as "excellent" in all the cases. All of the causative organisms (Escherichia coli in 3 and Enterobacter cloacae in 1) were eradicated by the treatment with AZT. Neither clinical side effect nor abnormal laboratory test value caused by AZT was observed. MICs of AZT against 10 clinical isolates (Staphylococcus aureus 1, E. coli 4, Klebsiella pneumoniae 1, E. cloacae 1, Haemophilus influenzae 1 and Pseudomonas aeruginosa 2) from neonatal patients with bacterial infections were examined. As results, AZT showed very good antibacterial activity comparable or even superior to cefoperazone, cefotaxime, latamoxef; however, the activity against P. aeruginosa was inferior to imipenem.(ABSTRACT TRUNCATED AT 250 WORDS)

Pharmacokinetic and clinical studies on aztreonam (AZT) were performed in neonates. Serum concentrations and urinary excretion of AZT were determined in 12 neonates with ages between 0 and 7 days (birth weights were between 1,260 and 3,500 g) upon intravenous injection or 1 hour drip intravenous infusion of AZT at 20 mg/kg. Serum concentrations of AZT at 1 hour after i.v. administration were 54.0 +/- 12.5 micrograms/ml, and half-lives were 6.01 +/- 0.70 hours. Serum concentrations of AZT reached their peaks at the end of drip infusion with levels of 42.1 +/- 17.6 micrograms/ml in the d.i.v. group and half-lives were 6.40 +/- 1.88 hours. Urinary recovery rates in the first 12 hours after administration were 28.5 +/- 6.4% for the i.v. group and 32.3 +/- 13.9% for the d.i.v. group. AZT was administered to 12 neonatal patients (2 cases of sepsis, 2 cases of suspected sepsis, 3 cases of pneumonia, 2 cases of urinary tract infection and 3 cases for prophylaxis), and clinical effectiveness, bacteriological efficacy and adverse reactions were evaluated. Clinical efficacies in 9 cases except 3 cases with prophylactic use were excellent in 1 case, good in 5 cases, fair in 1 case, poor in 1 case and unknown in 1 case, thus the efficacy rate was 75%. Bacteriological effects in 3 strains with Gram-negative bacilli were eradicated in 2 strains and unchanged in 1 strain, hence the bacteriological eradication rate was 66.7%. Increased GOT and GPT were observed in 1 cases as abnormal laboratory test results, but the abnormality was not serious.(ABSTRACT TRUNCATED AT 250 WORDS)

Serum concentration, urinary excretion and clinical application of aztreonam (AZT) were studied as follows: 1. Serum concentrations of AZT 1 hour after intravenous injection were 21.0 micrograms/ml in 1 case administered with approximately 10 mg/kg drug and 44.2 micrograms/ml on the average for 7 cases given approximately 20 mg/kg, indicating that serum concentrations are dose-dependent. Average serum half-life in 3 mature babies was 4.75 hours and that in 4 premature babies was 6.59 hours thus T 1/2 was longer in the latter. T 1/2 of 64 days of age newborn was 3.80 hours. Urinary recovery rates in 2 cases examined were 52.1 and 51.9%. 2. Daily dosages of AZT 39.9-63.3 mg/kg were intravenously administered to 10 newborns and prematures b.i.d. or t.i.d., 5 cases of which received AZT alone and the other 5 received AZT in combination with ampicillin (ABPC). Of the above 10 cases, AZT was given to 8 cases for treatment and to the other 2 cases for prophylaxis. Excluding 2 unascertainable cases, AZT showed good or better effectiveness in all the 6 cases in the treatment group, i.e., sepsis 1, suspected sepsis 1 and urinary tract infection 4 cases. All the identified pathogens (Escherichia coli 2 strains, Klebsiella pneumoniae 1 strain and Enterobacter 2 strains) were eliminated by the treatment. No onset of infection was observed in either of the 2 cases with prophylaxis. One of them was administered with AZT for 52 days consecutively but neither side effect nor abnormal laboratory test value was observed. 3. Side effect was not observed at all. One case each of minor degree of platelet increase and GOT elevation was recorded as an abnormal test value. The elevated GOT value continued to be high even after the completion of the administration and it was presumed to be due to the primary disease, heart failure. 4. As results of the above studies, AZT was considered to be effective and safe for neonatal infections caused by Gram-negative bacteria. It may be safer to initiate the treatment with AZT and ABPC in combination than with AZT alone before the identification of pathogen and to change the therapy to single administration of either AZT or ABPC when the pathogens are identified. With respect to method of administration, AZT 20 mg/kg 2 or 3 times a day appeared to show expected efficacy for the newborns with in 7 days after birth.
