OBJECTIVES: Echinocandins represent the first-line treatment of candidemia. Acquired echinocandin resistance is mainly observed among Candida albicans and glabrata and is associated with FKS hotspot mutations. The commercial Sensititre YeastOneTM (SYO) kit is widely used for antifungal susceptibility testing, but interpretive clinical breakpoints are not well defined. We determined echinocandins epidemiological cut-off values (ECV) for C. albicans/glabrata tested by SYO and assessed their ability to identify FKS mutants in a national survey of candidemia...

Vulvovaginal candidiasis (VVC) is an inflammatory disease of the vulva and vagina caused by different yeasts of the genus Candida which is responsible for infection in pregnant patients who attended Maternidade Escola Januário Cicco, Rio Grande do Norte, Brazil. From 41 samples, 19 yeasts were identified phenotypically as Candida albicans, and one as C. glabrata which is reported as the non-albicans species most frequently isolated from vulvovaginitis. The susceptibility to selected antifungal agents (fluocytosine, fluconazole, voriconazole, amphotericin B, caspofungin and micafungin) was determined, and the association between patient related signs and symptoms aided the construction of an epidemiological profile...

Background: Controversies remain over caspofungin dosage adjustments in cirrhosis, particularly Child-Pugh (CP) B or C. The product information for of caspofungin recommends a maintenance dose reduction from 50 to 35 mg for patients with CP-B cirrhosis. Objectives: To quantify the impact of cirrhosis and the severity of hepatic impairment on the pharmacokinetics (PK) of caspofungin. Patients and methods: We performed PK studies of a single 70 mg dose of caspofungin in patients with decompensated CP-B (n = 10) or CP-C (n = 10) cirrhosis and of multiple doses in 21 non-cirrhotic ICU patients with hypoalbuminaemia...

Caspofungin is an echinocandin antifungal agent licensed as a first-line therapy for invasive candidiasis in patients with moderate to severe illness or recent exposure to azoles. In this study we developed a whole-body physiology-based pharmacokinetics (WB-PBPK) model to predict the pharmacokinetics (PK) of caspofungin, and combined with Monte Carlo simulation (MCS) to optimize clinical dosage regimens of caspofungin in different kinds of patients. A WB-PBPK model of caspofungin was built and validated with raw data from 4 previous trials of general patients, intensive care unit (ICU) patients with Child-Pugh B, ICU patients on continuous renal replacement therapy, mild and moderate hepatic insuffciency (HI) patients...

Neoscytalidium spp. are ascomycetous fungi consisting of pigmented and hyaline varieties both able to cause skin and nail infection. Their color-based identification is inaccurate and may compromise the outcome of the studies with these fungi. The aim of this study was to genotype 32 isolates morphologically identified as Neoscytalidiumdimidiatum or N. dimidiatum var. hyalinum by multilocus sequence typing (MLST), differentiate the two varieties by their sequence types, evaluate their susceptibility to seven commercial antifungal drugs [amphotericin B (AMB), voriconazole (VOR), terbinafine (TER), 5-flucytosine (5FC), ketoconazole (KET), fluconazole (FLU), and caspofungin (CAS)], and also to the antimicrobial photodynamic treatment (APDT) with the phenothiazinium photosensitizers (PS) methylene blue (MB), new methylene blue (NMBN), toluidine blue O (TBO) and the pentacyclic derivative S137...

Candidiases are the most recurrent fungal infections, especially among immunosuppressed patients. Although Candida albicans is still the most widespread isolated species, non-Candida albicans Candida species have been increasing. The goal of this work was to determine the susceptibility of C. glabrata biofilms to echinocandins and to evaluate their effect on the biofilm matrix composition, comparing the results with other Candida species. Drug susceptibilities were assessed through the determination of minimum inhibitory concentration (MIC), minimum fungicidal concentration (MFC) and minimum biofilm eradication concentration (MBEC) of caspofungin (Csf) and micafugin (Mcf)...

Invasive aspergillosis (IA) affects lungs and disseminates mostly in patients with neutropenia and/or receiving immunosuppressive and steroid therapies. Despite progress in diagnosis and therapy of IA, it is still characterized by a high mortality rate. Currently, voriconazole is considered as the standard therapy for invasive aspergillosis. Over the recent years, triazole resistant Aspergillus fumigatus isolates have emerged in the environment due to the use of fungicidal agricultural products with the risk of developing IA related to a resistant isolate...

The emerging human fungal pathogen Candida auris has been recognized as a multidrug resistant species and is associated with high mortality. This fungus was first described in Japan in 2009 and has been reported in at least 18 countries on five continents. In this study, we report the first isolate of C. auris from the bronchoalveolar lavage fluid (BALF) of a hospitalized woman in China. Interestingly, this isolate is susceptible to all tested antifungals including amphotericin B, fluconazole, and caspofungin...

Neutrophils are the first white blood cells to respond to microbes and to limit their invasion of the body. However, the growth of the microbes into colonies often challenges the neutrophils ability to contain them. To study the interactions between neutrophils and microbial colonies, we designed an assay for arranging microbes in clusters of controlled size (i.e. living colloids). The patterned microbes in the living colloid are mechanically trapped inside the wells and fully accessible to neutrophils. Using the assay, we studied the interactions between human neutrophils and Candida albicans and Staphylococcus aureus, two common human pathogens...

The role of penetration limitation in Candida biofilm-associated antifungal resistance remains unclear. Most of the previous work has been done on Candida albicans, although non-albicans (NAC) species are also implicated in invasive candidiasis and the biofilm matrix has been shown to vary amongst different species. Only a few studies have evaluated clinical isolates. This study aimed to determine the relevance of penetration limitation in the antifungal resistance of biofilms formed by C. albicans and NAC clinical isolates, using an agar disk diffusion assay...

The importance of antifungal agents and their clinical implications has received little attention in comparison to antibiotics, particularly in the health-care setting. However, apart from bacterial infections rising in hospitals, the incidences of fungal infections are growing with the development of resistance to conventional antifungal agents. Newer antifungal agents such as echinocandins (ECs) have been extensively studied over the past decade and are recognised as a superior treatment compared with prior antifungals as a first line of therapy in tertiary institutions...
