BACKGROUND: The most optimal antifungal agent for empiric treatment of invasive fungal diseases (IFDs) in febrile neutropenia is controversial. Our objective was evaluate the relative efficacy of antifungals for all-cause mortality, fungal infection-related mortality and treatment response in this population. METHODS: Pubmed, Embase and Cochrane Library were searched to identify randomized controlled trials (RCTs). Two reviewers performed the quality assessment and extracted data independently...

In August 2015, Dipodascus capitatus was isolated from two patients admitted to the neonatal intensive care unit. Nosocomial acquisition of the fungus was suspected and epidemiological studies were undertaken. The patients were simultaneously hospitalized, and the comparison of the two isolates by two independent molecular typing methods have confirmed clonal dissemination of a single strain of D. capitatus. Antimicrobial susceptibility testing was useful for identifying the appropriated antifungal therapy in micafungin...

Various fungi have the ability to colonize surfaces and to form biofilms. Fungal biofilm-associated infections are frequently refractory to targeted treatment because of resistance to antifungal drugs. One fungus that frequently colonises the respiratory tract of cystic fibrosis (CF) patients is the opportunistic black yeast-like fungus Exophiala dermatitidis. We investigated the biofilm-forming ability of E. dermatitidis and its susceptibility to various antiinfective agents and natural compounds. We tested 58 E...

Kodamaea ohmeri is a rare yeast pathogen that has recently emerged as an important cause of fungemia in immunocompromised patients. However, appropriate therapy for this infection remains unclear. We report a case of catheter-related blood stream infection caused by K. ohmeri in a 58-year-old patient who improved after removal of the central venous catheter and administration of micafungin. Considering the antibiotic susceptibility of this pathogen and reviewing literature, echinocandins may be the first choice for an empiric therapy for this pathogen...

REVIEW
C C Chang, M A Slavin, S C-A Chen
The echinocandins-caspofungin, anidulafungin and micafungin-are semi-synthetic cyclic hexapeptide antimicrobial agents with modified N-linked acyl lipid side chains which anchor the compounds to the phospholipid bilayer of the fungal cell membrane, thereby inhibiting synthesis of fungal cell wall glucan. Over the last 10 years, echinocandins have become the first-line antifungal treatment of candidaemia and other forms of invasive candidiasis (IC). Echinocandins are generally well tolerated, but their use is limited by their requirement for daily intravenous dosing, lack of oral formulation and limited spectrum...

Saprochaete and Geotrichum spp. are rare emerging fungi causing invasive fungal diseases in immunosuppressed patients and scarce evidence is available for treatment decisions. Among 505 cases of rare IFD from the FungiScope(™) registry, we identified 23 cases of invasive infections caused by these fungi reported from 10 countries over a 12-year period. All cases were adults and previous chemotherapy with associated neutropenia was the most common co-morbidity. Fungaemia was confirmed in 14 (61%) cases and deep organ involvement included lungs, liver, spleen, central nervous system and kidneys...

The available data focused on breakthrough candidemia (BC) in allogeneic hematopoietic stem cell transplant (allo-HSCT) recipients were rare. BC has been defined as candidemia that develops on being administered antifungal agents (AAs). Medical and microbiological records of the recipients who had received allo-HSCT between December 2008 and December 2014 were reviewed. Out of 768 allo-HSCT cases, 26 developed BC. Among the 26 causative strains, 22 strains were stored and identified by sequencing. The following species were isolated: C...

INTRODUCTION: Non-Candida opportunistic yeasts are emerging causes of bloodstream infection (BSI) in immunocompromised hosts. However, their clinical presentation, management, and outcomes in stem cell transplant (SCT) recipients are not well described. CASE REPORT AND REVIEW: We report the first case to our knowledge of Pseudozyma BSI in a SCT recipient. He had evidence of cutaneous involvement, which has not been previously described in the literature. He became infected while neutropenic and receiving empiric micafungin, which is notable because Pseudozyma is reported to be resistant to echinocandins...

Currently, echinocandins are first-line drugs for treatment of invasive candidiasis. However, data on how serum influences killing activity of echinocandins against uncommon Candida species are limited. Therefore, the killing activity of micafungin in RPMI-1640 and in 50% serum was compared against Candida guilliermondii, Candida lusitaniae, and Candida kefyr. Minimum inhibitory concentration (MIC) ranges in RPMI-1640 were 0.5-1, 0.12-0.25, and 0.06-0.12 mg/L, respectively. In 50% serum, MICs increased 32- to 256-fold...

The activity of CD101 and comparators was evaluated against 606 invasive fungal isolates collected worldwide during 2014 using the CLSI method. All C. albicans (n=251), C. tropicalis (n=51), C. krusei (n=16), and C. dubliniensis (n=11) were inhibited by ≤0.12 μg/ml of CD101 and were susceptible or wild type to other echinocandins. Five C. glabrata (n=100) displayed CD101 MIC values of 1-4 μg/ml, elevated caspofungin (2->8 μg/ml), anidulafungin (2-4 μg/ml), and micafungin (2-4 μg/ml) MICs, and carried mutations on fks1/fks2 C...

BACKGROUND: Echinocandins are an important class of antifungal agents in the treatment of invasive candidiasis. However, little is known about the metabolomic effects of echinocandins on Candida We therefore performed LC-high-resolution MS (LC-HRMS)-based metabolomics profiling of the response of Candida albicans cells to increasing concentrations of micafungin to determine the metabolic response of Candida to micafungin subinhibitory injury. METHODS: Isolates of C...

Scopulariopsis brevicaulis onychomycosis with local cutaneous invasion was diagnosed in an acute leukemia patient and unsuccessfully treated with high-dose micafungin, based on antifungal susceptibility testing. This case should alert clinicians to the possible severe evolution of onychomycosis in neutropenic patients and suggests that surgery should be preferred in such a situation.

REVIEW
Markus Ruhnke, Stefan Schwartz
Patients with hematological cancer have a high risk of invasive fungal diseases (IFDs). These infections are mostly life threatening and an early diagnosis and initiation of appropriate antifungal therapy are essential for the clinical outcome. Most commonly, Aspergillus and Candida species are involved. However, other non-Aspergillus molds are increasingly be identified in cases of documented IFDs. Important risk factors are long lasting granulocytopenia with neutrophil counts below 500/μl for more than 10 days or graft-versus-host disease resulting from allogeneic stem-cell transplantation...

COMPARATIVE STUDY
David Cretella, Katie E Barber, S Travis King, Kayla R Stover
The rising rates of invasive fungal infections caused by non-albicans Candida and the increasing emergence of antifungal resistance complicate the management of invasive candidiasis. Accurate and timely antifungal susceptibility testing is critical to targeting antifungal therapy. The purpose of this study was to compare commercially available susceptibility testing methods using prospectively collected Candida isolates. Susceptibility testing was performed on 74 Candida isolates collected from July 2014 to March 2015 using broth microdilution according to the Clinical and Laboratory Standards Institute method, Etest, Vitek 2 (YS-05) and Sensititre...
