RESUMO

Although extended-spectrum ß-lactamase (ESBL)-producing Enterobacteriaceae have become a worldwide public health concern, little is known regarding the clinical course of colonized or infected individuals. Our objective was to characterize the determinants of fatal outcomes related to ESBL-producing microorganisms at a large hospital in Paris, France. In 2012-2013, all consecutive patients with clinical samples testing positive for ESBL-producing Enterobacteriaceae at Saint-Antoine Hospital were identified. Patient clinical data were obtained at hospital entry, while information on intensive care unit (ICU) admissions and death were prospectively collected. Risk-factors for fatal 1-year outcomes were assessed using logistic regression. In total, 643/4684 (13%) ESBL-positive samples were observed, corresponding to 516 episodes (n = 206, 40% treated) among 330 patients. Most episodes were nosocomial-related (n = 347/516, 67%) involving Escherichia coli (n = 232/516, 45%) or Klebsiella pneumoniae (n = 164/516, 32%). Empirical antibiotic therapy was adequate in 89/206 (43%) infections, while the median length of hospital stay was 30 days [interquartile range (IQR) = 11-55] and 39/201 (19%) were admitted to the ICU. Overall, 104/241 patients (43%) with available data died within 1 year. In the multivariable analysis, 1-year death was associated with age >80 years (p = 0.01), concomitant comorbidity (p = 0.001), nosocomial-acquired infection (p = 0.002), and being infected rather than colonized (p < 0.001). In this series of patients with identified samples of ESBL-producing Enterobacteriaceae, hospital burden was large and 1-year mortality rates high. Understanding which patients in this setting would benefit from broad-spectrum empirical antibiotic therapy should be further examined.

RESUMO

Establishment of an effective prophylaxis against oral candidiasis by local treatment is essential for immunocompromised patients. The aim of the study is to assess effectiveness and stability of antifungal suspensions for mouthrinses. The assessed suspensions are compounded by one solvent among sterile water, spring water or sodium bicarbonate associated with amphotericin B (Fungizone®) or nystatine (Mycostatine®). Two others mixes are assessed: Mycostatine®-bicarbonate and Mycostatine®-Hextril®-bicarbonate as well as the two straight antifungal. In vitro activity is tested on five Candida species (C. albicans, C. glabrata, C. krusei, C. parapsilosis, C. tropicalis) after a five minutes contact between yeasts and the assessed suspension. A galenic study is realized during 3 days. Mixes associating a polyene with sodium bicarbonate have no effectiveness on Candida albicans, others mixes shows intermediate effectiveness (the percentage of yeast growth inhibition lies between 35% and 68%). Effectiveness results of Hextril®-based mixes are not explainable because of alcohol in its composition. Spring water-based mixes must be evicted due to microbiologic contaminations after 48hours. Mycostatine®-Hextril®-bicarbonate mix is not stable during 3 days. All those mouthrinses, poorly effective, excepted on C. glabrata, should be avoided. Straight Mycostatine® shows a good antifungal effectiveness excepted on C. krusei and its use should be recommended.
