The urinary concentrations of fosfomycin trometamol, norfloxacin, pipemidic acid and cotrimoxazole were studied at various times after oral administration of drugs in healthy volunteers. Using the same urine, the bactericidal activity of four antimicrobial agents against Escherichia coli, Proteus mirabilis and Klebsiella pneumoniae in an in vitro model simulating the treatment of bacterial cystitis was also evaluated. The results obtained show that very high concentrations of the drugs were achieved in urine particularly after the oral administration of the fosfomycin trometamol. In the bladder model bactericidal activity of fosfomycin trometamol, norfloxacin and pipemidic acid were higher than that of cotrimoxazole; no resistant mutants to drugs were selected over a period of 24 h.

Given the prevalence of complicated urinary tract infection (UTI) and the resistance patterns of common uropathogens, antimicrobial therapy for complicated UTI must be carefully selected. For patients with complicated UTI who can be treated with oral medication, the quinolones or trimethoprim-sulfamethoxazole (TMP-SMX) are reasonable treatment choices. Enoxacin and TMP-SMX were compared for efficacy, safety, and bacteriologic response in this study. A total of 260 patients with complicated UTI were enrolled in a multicenter, open-label, randomized study and received enoxacin or TMP-SMX. Short-term assessments 5 to 9 days posttherapy and long-term assessments 4 to 6 weeks posttherapy included physical and clinical evaluations, laboratory testing, urine cultures, and susceptibility testing. Although enoxacin and TMP-SMX demonstrated comparable short-term efficacy rates, enoxacin exerted a potent, long-term bacteriologic response, particularly against Escherichia coli. Enoxacin therapy achieved a 94.7% long-term eradication rate against E coli compared with a 76.0% eradication rate against this pathogen with TMP-SMX. Most adverse events were mild, and a comparable incidence (approximately 17%) occurred in both treatment groups. These data indicate that enoxacin is an excellent addition to the armamentarium of agents commonly used in the treatment of patients with complicated UTI.

Drugs considered of choice against uncomplicated urinary tract infections are facing high resistance prevalences and resistance determinants formerly seen only at hospitals are now among community strains. Treatment guidelines from developed countries might not reflect these local trends.
The efficacy and safety of norfloxacin were compared with those of placebo, vancomycin-polymyxin, and trimethoprim-sulfamethoxazole (TMP/SMX) for prophylaxis of bacterial infections in granulocytopenic patients. The study results showed that norfloxacin treatment, which was well tolerated and not associated with any serious systemic adverse effects, prevented acquisition of gram-negative bacillary organisms. Fewer norfloxacin-treated patients (38 of 108 patients, or 35 percent) experienced microbiologically documented infections compared with patients receiving placebo (27 of 40 patients, or 68 percent), vancomycin-polymyxin (16 of 30 patients, or 53 percent), or TMP/SMX (14 of 28 patients, or 50 percent). Gram-negative bacteremia developed in five of 108 norfloxacin-treated patients (5 percent), compared with 17 of 40 placebo-treated patients (43 percent), five of 30 treated with vancomycin-polymyxin (17 percent), and one of 28 patients treated with TMP/SMX (4 percent). The incidence of gram-positive bacteremia was similar in all study groups and was not affected by norfloxacin or any other oral prophylactic antibiotics. These results suggest that norfloxacin is both safe and effective for the prevention of serious gram-negative bacillary infections in granulocytopenic patients. More effective prophylaxis of gram-positive bacterial infections, however, is needed.

Despite important differences in the management of acute pyelonephritis in Ile-de-France, a majority of the units follows similar therapeutic modalities. In the absence of consensus, new recommendations are necessary concerning the management of pyelonephritis in infants and children in France.

Forty nine patients were included in this study. The most common underlying diseases were HIV and malignancies. The mean (+/- standard deviation) age of the 49 patients was 54 +/- 20.2 years (range, 5 to 96 years). The mean CD4+ T-lymphocyte count was 110 cells/microL (range, 0-670 cells/microL). Although the mean CD4+ T-lymphocyte count of the non-HIV group was higher than that of the HIV group (165 +/- 78 cells/microL vs 57.5 +/- 97 cells/microL), statistical significance was not obtained (p=0.087). Arterial oxygenation (ratio of arterial oxygenation to fraction of inspired oxygen) was less than 200 mm Hg in 28 patients. Lactate dehydrogenase levels were higher than the normal range in 15 patients. A significantly higher proportion of patients died in the group without HIV compared with the HIV-infected patients (17/34 [50.0%] vs 1/15 [6.7%]; p=0.004).

S. flexneri is predominant in Anhui, China, and its higher antimicrobial resistance rate compared with that of S. sonnei is a cause for concern. Continuous monitoring of resistance patterns is necessary to control the spread of resistance in Shigella. The recommendations for antimicrobial treatment must be updated regularly based on surveillance results.

In multivariable analyses controlling for patient characteristics and indication for antimicrobial drug use, clarithromycin (odds ratio [OR], 3.96 [95% CI, 2.42-6.49]), levofloxacin (OR, 2.60 [95% CI, 2.18-3.10]), sulfamethoxazole-trimethoprim (OR, 2.56 [95% CI, 2.12-3.10]), metronidazole (OR, 2.11 [95% CI, 1.28-3.47]), and ciprofloxacin (OR, 1.62 [95% CI, 1.33-1.97]) were associated with higher rates of hypoglycemia compared with a panel of noninteracting antimicrobials. The number needed to harm ranged from 71 for clarithromycin to 334 for ciprofloxacin. Patient factors associated with hypoglycemia included older age, female sex, black or Hispanic race/ethnicity, higher comorbidity, and prior hypoglycemic episode. In 2009, 28.3% of patients prescribed a sulfonylurea filled a prescription for 1 of these 5 antimicrobials, which were associated with 13.2% of all hypoglycemia events in patients taking sulfonylureas. The treatment of subsequent hypoglycemia adds $30.54 in additional Medicare costs to each prescription of 1 of those 5 antimicrobials given to patients taking sulfonylureas.
