Thirty children over the age of one month were treated with amikacin (BBK8), a new aminoglycoside derived from kanamycin A, with three intramuscular dosage schedules. Each group consisted of ten patients. The first received 7-5 mg/kg/12 hours, the second 7-5 mg/kg/24 hours and the third, 3-75 mg/kg/12 hours. The infections and the bacteria were similar in all three groups: pyelonephritis, abscesses of soft tissues, infected wounds, septicaemia, superinfected empyema, gastro-enteritis, chronic otitis media; the bacteria were E. coli, Klebsiella, Pseudomonas and Salmonella. A were sensitive by the Kirby-Bauer method, although two were resistant by dilution in Petri dish. Of the thirty patients, twenty four (80%) were cured. The schedule of 3-75 mg/kg/12 hours was as effective as the schedule of 7-5 mg/kg/12 hours for infections such as pyelonephritis, superficial abscesses, contaminated wounds, gastro-enteritis and sepsis. The cases with infections localized in rather unaccessible sites required double the dose and strict drainage and cleanliness. Plasma levels with the administration of 3-75 mg/kg fluctuated between 8-3 and 12-6 mcg/ml; with 7-5 mg/kg they fluctuated between 8-6 and 13-1. The minimum inhibitory level (MIL) for the majority of the bacteria was 1-25 mcg/ml. No toxic reactions were observed.

The antibacterial activity of levofloxacin was compared with those of ofloxacin, ciprofloxacin, and other antibiotics. In general, levofloxacin was equally active or up to fourfold more active than ofloxacin against all 801 organisms tested. Levofloxacin was twofold [corrected] more active than ciprofloxacin against Streptococcus pneumoniae and 2- to 4-fold more active than ciprofloxacin against Staphylococcus aureus, Xanthomonas maltophilia, and Bacteroides fragilis. Levofloxacin was two- to eightfold more active than ciprofloxacin against coagulase-negative staphylococci and Acinetobacter spp., although these improvements in potency may not be clinically relevant. Levofloxacin inhibited 90% of streptococci when it was used at concentrations of 1 to 2 micrograms/ml. Levofloxacin was two- to fourfold less active than ciprofloxacin against most members of the family Enterobacteriaceae, such as Escherichia coli; Klebsiella pneumoniae; Citrobacter, Proteus, Providencia, Salmonella, and Yersinia spp.; and Pseudomonas aeruginosa. Both compounds were equally active against Pseudomonas cepacia. The in vitro DNA gyrase inhibitory activity of levofloxacin was as potent as that of ciprofloxacin, with a 50% inhibitory concentration of 0.65 micrograms/ml against an E. coli enzyme. In vivo, oral treatment with levofloxacin was as efficacious or more efficacious than that with ciprofloxacin in systemic as well as pyelonephritis infections in mice. Levofloxacin achieved higher concentrations in the serum and tissue of mice than did ciprofloxacin. This study presents some potential advantages of the pure L isomer of ofloxacin over ciprofloxacin and other quinolones.

The pharmacokinetics and the clinical effectiveness of meropenem (MEPM) were examined in the field of pediatrics. The results are summarized as follows. 1. A 4-year-6-month-old girl with suppurative meningitis (Haemophilus influenzae) was treated by intravenous drip infusion of MEPM in a daily dose of 29 mg/kg which was divided into 4 dosages, each dosage being infused over 30 minutes, and the drug concentration in cerebrospinal fluid was determined. Upon completion of infusion on the 2nd day of treatment, the drug concentration was 2.52 micrograms/ml, which corresponded to 3.6% of the drug concentration in the blood. 2. MEPM was used in 10 patients, including 3 with suppurative lymphnoditis, 2 with staphylococcal scalded skin syndrome (SSSS) and 1 each with pneumonia, suppurative meningitis, suppurative knee arthritis, facial phlegmon and pyelonephritis. The daily doses ranged from 30 to 117.6 mg/kg, divided into 3 to 4 dosages and administered via intravenous drip infusion over 30 minutes. Clinical responses were evaluated as very good in 7 patients, good in 2 patients and fair in 1 patient, with an efficacy rate of 90%. 3. Isolated pathogens were 2 strains of Staphylococcus aureus, 1 strain of Klebsiella pneumoniae and 3 strains of Haemopilus influenzae. All of the 6 strains were eradicated, with an eradication rate of 100%. 4. In the safety evaluation, none of the patients was observed to have any side effects. Furthermore, no abnormal variations were found in laboratory test data possibly attributable to administration of MEPM.

The protective effect of immunization with a polyvalent vaccine (SolcoUrovac) was studied in the mouse and the rat. The i.m. immunization increased the resistance of mice to challenge infection with all homologous strains of bacteria. The LD50 values for E. coli, Proteus mirabilis and Streptococcus were 3.5-4.5 times and that of Klebsiella as much as 600 times that in nonimmunized mice. Protection against challenge with heterologous E. coli was also achieved and persisted for about 20 weeks. Immunization with the vaccine also provided marked protection against pyelonephritis in rats. Kidneys with abscesses were seen only one-third as often as in controls, and the size of the individual abscesses was substantially smaller in the vaccinated animals. Based on the quantity of bacteria in the kidneys it was postulated that the vaccination increased the clearance of bacteria.

Cefetamet pivoxil was investigated in an open, randomized comparative study involving a total of 37 children with acute pyelonephritis, whose ages ranged from 2 to 14 years. The patients received either 10 mg/kg (n = 18) or 20 mg/kg (n = 8) cefetamet pivoxil twice daily, or 30-50 mg/kg amoxycillin/clavulanic acid three times daily (n = 11) for a period of 7-10 days. Escherichia coli was the main causative agent isolated in 28 (75.7%) of the patients; other pathogens included Proteus mirabilis (three patients). Proteus species (one patient), Klebsiella pneumoniae (two patients), Pseudomonas diminuta (one patient) and mixed infections (three patients). No differences in the overall treatment outcome could be observed between the treatment regimens used and, at the end of treatment, all pathogens were eradicated with neither relapse, nor persistence of the isolated pathogen, nor reinfection occurring. The clinical signs and symptoms had subsided in all patients at treatment end and the tolerability of the trial drugs was found to be satisfactory with no premature treatment withdrawal required. It is concluded that cefetamet pivoxil in the standard twice-daily dose of 10 mg/kg was equally effective and as well tolerated as 20 mg/kg cefetamet pivoxil given twice daily or 30-50 mg/kg amoxycillin/clavulanic acid given three times daily.

The efficacy and safety of parenteral ofloxacin were evaluated in an open, multicenter study of hospitalized patients with pyelonephritis. The patients received ofloxacin 400 mg IV as an initial dose followed by ofloxacin 200 mg IV b.i.d. for a minimum of three days. The patients could then continue ofloxacin orally 200 mg b.i.d. for a total of seven to fourteen days. The most common pathogens isolated were Escherichia coli, Enterobacter cloacae, and Klebsiella pneumoniae. Microbiologic eradication was achieved in 65 of 66 evaluable patients (98%), and clinical cure or clinical improvement was noted in all patients. Of 82 patients evaluable for safety, 12 (15%) reported drug-related adverse events, the most frequent of which was pruritus or rash. None of the patients experienced drug-related central nervous system symptoms. Ofloxacin is well tolerated and highly effective in the treatment of pyelonephritis.

The authors report on 48 patients with calculous pyelonephritis. Urinary obstruction was caused by renal calculi in 21 patients and ureteral calculi in 27. Urine cultures were positive in 87.5% and bacteremia was seen in 70%. The common organisms in urine and blood culture were E. coli, Proteus and Klebsiella. Septic shock occurred in 10 (20.8%) out of 48 patients. Calculous pyelonephritis with urinary obstruction is a very serious condition.

Pyelonephritis emphysematous (PE) is a life threatening renal infection which is observed practically exclusively as a serious complication of diabetes mellitus. 95% of the 73 cases which have been reviewed were found in diabetic patients. The symptomatology resembles that of severe acute pyelonephritis but the disease differs from this in that, in PE, emphysema develops in the actual renal parenchyma and/or in the perirenal tissues. The most important single factor in the etiology appears to be ischaemia of the tissues which are employed as growth media for the microorganisms involved. Infections with E. coli, Klebsiella pneumoniae, Aerobacter and Proteus are the most commonly found. Isolated cases with Candida and Cryptococcus neoformans have been observed. The mortality in untreated cases of PE is 100%. With medical treatment alone, the mortality decreases to 73% while, when combined medical and surgical intervention is employed, the mortality can be reduced to 30%.

On the fifth day of a course of antibiotic therapy for acute Klebsiella pyelonephritis, a 21-year-old pregnant woman developed adult respiratory distress syndrome. She improved rapidly on fluid restriction and intravenous furosemide and did not require mechanical ventilation. 17 weeks later, after 40 weeks of pregnancy, she spontaneously delivered a healthy male infant weighing 3280 g.

In a prospective, open clinical study, 50 urological patients with acute pyelonephritis were treated with the oral cephalosporin cefixime. The medication (2 x 200 mg/day) was given for seven to ten days. Clinical, bacteriological as well as hematological examinations were carried out prior to, during and immediately after therapy. A late check-up was performed five to nine days after the end of therapy. 46 of the 50 cases were evaluable for efficacy, and all 50 patients were included in safety evaluation. The most frequent pathogens isolated prior to therapy were Escherichia coli (34 times), Proteus mirabilis (six times), Klebsiella pneumoniae (twice) and coagulase-negative staphylococci (twice). Immediately after the end of therapy the pathogens were eradicated in 44 (97.5%) patients. At the late check-up the urine was sterile in 29 (63%) patients. A relapse was observed in 11 patients, a reinfection in four and the initially isolated pathogens had persisted in two. Immediately after the end of therapy 44 (95.7%) patients were clinically cured and two patients had improved. At the late check-up 41 patients were classified as clinically cured, three showed improvement, and two improvement with relapse. Adverse reactions (one case nausea and exanthem, and one case of meteorism) occurred in two patients. No changes in the blood counts or in the liver and kidney functions were observed. In the study described here cefixime proved to be an effective and well tolerated antibiotic for the treatment of upper urinary tract infections; it is of particular interest that 16 of the 50 patients presented with underlying disease favoring infection.
