OBJECTIVE To estimate the cost-effectiveness of three echinocandins (anidulafungin, caspofungin, and micafungin) and generic fluconazole in the treatment of nonneutropenic adult patients with candidemia and/or invasive candidiasis in intensive care units in Spain. MATERIALS AND METHODS A decision-tree model was applied. The success and safety (hepatic and renal adverse effects) of first-line ...

Our objective was to evaluate the maximum tolerated dose of caspofungin for invasive aspergillosis (IA). The safety and pharmacokinetics of escalating dosages of caspofungin were investigated in IA. Eight patients each received caspofungin 70, 100, 150, or 200 mg once a day (QD). Dose-limiting toxicity (DLT) was defined as the same non-hematological treatment-related adverse event of grade ≥ 4 ...

The Platelia Aspergillus antigen enzyme-linked immunosorbent assay (ELISA) (Bio-Rad, Marnes-la-Coquette, France) has become an important tool for the early detection of invasive aspergillosis in immunocompromised patients (4). This ELISA uses a rat monoclonal antibody (EB-A2) which reacts with -(1,5)-galactofuranose, a side chain of galactomannan (GM). Cross-reactivity of the Platelia ELISA wit...

A high-dose-step-down strategy for caspofungin treatment was evaluated in an experimental model of advanced-stage invasive pulmonary aspergillosis. The therapeutic efficacy of caspofungin in relation to the severity of invasive pulmonary infection caused by Aspergillus fumigatus in transiently neutropenic rats was investigated by using rat survival and the decrease in the fungal burden as the p...

BACKGROUND Candiduria is a rising condition among hospitalized patients and Candida albicans is the most common recovered agent. However, non-albicans Candida species (NACs) such as C. glabrata, C. krusei, C. parapsilosis, and C. tropicalis are also important. Although most Candida species especially C. albicans are sensitive to routinely used antifungals, an increasing trend in resistance has ...

BACKGROUND Invasive candidiasis is an important cause of morbidity and mortality among patients with health care-associated infection. The echinocandins have potent fungicidal activity against most Candida species, but there are few data comparing the safety and efficacy of echinocandins in the treatment of invasive candidiasis. METHODS This was an international, randomized, double-blind tria...

BACKGROUND Consecutive Candida glabrata isolates recovered from a patient in an intensive care unit were resistant to amphotericin B (minimum inhibitory concentration, up to 32 mu g/mL; determined by Etest [AB Biodisk]). Analyses at the national reference laboratory showed that some isolates were also resistant to azoles and caspofungin. In this study, 4 isolates were studied thoroughly using s...

A commercially prepared, dried colorimetric microdilution panel (Sensititre YeastOne Trek Diagnostic Systems, Cleveland, OH) was compared in three different laboratories with the Clinical and Laboratory Standards Institute (CLSI) reference microdilution method by testing 2 quality control strains, 25 reproducibility strains, and 404 isolates of Candida spp. against anidulafungin, caspofungin, a...

Biofilms play a major role in Staphylococcus aureus pathogenicity but respond poorly to antibiotics. Here, we show that the antifungal caspofungin improves the activity of fluoroquinolones (moxifloxacin, delafloxacin) against S. aureus biofilms grown in vitro (96-well plates or catheters) and in vivo (murine model of implanted catheters). The degree of synergy among different clinical isolates ...

Candida albicans, a clinically important dimorphic fungal pathogen that can evade immune attack by masking its cell wall beta-glucan from immune recognition, mutes protective host responses mediated by the Dectin-1 beta-glucan receptor on innate immune cells. Although the ability of C. albicans to switch between a yeast- or hyphal-form is a key virulence determinant, the role of each morphotype...
