Comparison between Disk Diffusion and Microdilution Methods for Determining Susceptibility of Clinical Fungal Isolates to Caspofungin

2007

ABSTRACT We compared the caspofungin (CAS) susceptibility testing results generated by the disk diffusion (DD) assay with the results of the Clinical and Laboratory Standards Institute (CLSI) broth microdilution (BD) reference method for 106 yeast isolates. The isolates represented 11 different fungal species, including Candida albicans ( n = 50), C. parapsilosis ( n = 10), C. glabrata ( n = 10), C. tropicalis ( n = 10), C. guillermondii ( n = 6), C. rugosa ( n = 5), C. krusei ( n = 5), C. kefyr ( n = 2), C. pelliculosa ( n = 2), Saccharomyces cerevisiae ( n = 3), and Geotrichum candidum ( n = 3). The DD assay was performed in supplemented Mueller-Hinton agar with CAS, which was tested at c…

International Multicentre Study of Candida auris Infections

2021

Background:Candida auris has emerged globally as a multi-drug resistant yeast and is commonly associated with nosocomial outbreaks in ICUs. Methods: We conducted a retrospective observational multicentre study to determine the epidemiology of C. auris infections, its management strategies, patient outcomes, and infection prevention and control practices across 10 centres from five countries. Results: Significant risk factors for C. auris infection include the age group of 61–70 years (39%), recent history of ICU admission (63%), diabetes (63%), renal failure (52%), presence of CVC (91%) and previous history of antibiotic treatment (96%). C. auris was commonly isolated from blood (76%). Echi…

Evaluation of the Disk Diffusion Method Compared to the Microdilution Method in Susceptibility Testing of Anidulafungin against Filamentous Fungi

2008

ABSTRACT Susceptibility testing of anidulafungin (AFG) against 32 mold isolates showed an excellent correlation between disk diffusion (DD) and broth microdilution methods. Based on our data, a 2-μg disk of AFG and a 24-h reading time might represent the best parameters for AFG DD testing against filamentous fungi.

Posaconazole concentrations in the central nervous system

more susceptible to the killing activity of caspofungin. This study is the first comparing caspofungin killing activity against the closely related species C. parapsilosis, C. orthopsilosis and C. metapsilosis. Killing curves, regardless of the medium used, showed a decreasing order of susceptibility to caspofungin: C. metapsilosis . C. orthopsilosis . C. parapsilosis. Based on high echinocandin MICs for C. parapsilosis sensu stricto, in the case of isolates identified as C. parapsilosis sensu lato low MICs of echinocandins may be regarded as an indicator that an isolate is in fact C. orthopsilosis or C. metapsilosis; in the case of isolates with low echinocandin MICs, DNA-based identificat…

Anidulafungin in combination with amphotericin B against Aspergillus fumigatus.

2009

ABSTRACT We investigated the effects of anidulafungin alone and in combination with amphotericin B against Aspergillus fumigatus . Indifference was the only type of interaction observed in vitro. Anidulafungin at 1 and 5 mg/kg of body weight/day, amphotericin B at 1 mg/kg/day, and combination therapy prolonged the survival of mice with invasive aspergillosis. Anidulafungin at 5 mg/kg/day, alone and in combination with amphotericin B, reduced the kidney fungal burden. Overall, the combination was not superior to the most active single drug.

Safety of micafungin in prospective and retrospective clinical trials

2012

Summary Managing fungal diseases remains a major challenge for clinicians despite the improved armamentarium of antifungal agents. This review identified 19 publications reporting safety data on micafungin. Two of these publications were spin off publications, the remaining 17 (15 prospective, two retrospective) were included in the main assessment. Major adverse events reported which occurred in more than 2% in the study populations were infusion-related, gastro-intestinal and hepatic (LFT parameters elevations). Micafungin demonstrated significantly less renal events compared with liposomal amphotericin B and less hepatic events compared with voriconazole. Compared with fluconazole no sig…

Economic evaluation of caspofungin vs liposomal amphotericin B for empirical therapy of suspected systemic fungal infection in the German hospital se…

2007

As antifungal agents are frequently used in hematology and oncology, economic data on the empirical therapy of suspected systemic fungal infection are pivotal. Data were analyzed according to: (1) the rate of nephrotoxicity related to treatment with caspofungin in comparison to liposomal amphotericin B (L-AmB) from a randomized clinical trial, (2) the effect of nephrotoxicity on length of hospital stay from a European observational study, and (3) an example of total bottom-up cost in a department of hematology in Germany. All estimates include 95% confidence intervals (CI) using two-stage Monte Carlo simulation on binominal and Gaussian random variables from separate studies with comparable…
