Invasive fungal infections (IFI) are complications after liver transplantation involving high morbidity and mortality. (1,3)-β-d-glucan (BG) is a biomarker for IFI, but its utility remains uncertain. This study was designed to evaluate the impact of BG following their diagnosis. Between January 2013 and May 2016, 271 liver transplants were performed in our institution. Serum samples were tested for BG (Fungitell(®), Associates Cape Code Inc., Falmouth, MA, USA) at least weekly between liver transplantation and the discharge of patients...

BACKGROUND: Measurement of serum (1,3)-β-D-glucan has emerged as an important diagnostic strategy for invasive fungal infections (IFI). Previous studies suggested that the eosinophil count would be related with the value of serum (1,3)-β-D-glucan. METHODS: 572 blood samples obtained from 126 patients at the First Affiliated Hospital of Zhengzhou University were analyzed. The unsuitable samples were excluded according to the patient selection. RESULTS: In our study, we found that in the 572 cumulative results, the absolute eosinophil count was significantly associated with the value of (1,3)-β-D-glucan (r = 0...

Enterococcus faecalis, a Gram-positive bacterium, and Candida albicans, a fungus, occupy overlapping niches as ubiquitous constituents of the gastrointestinal and oral microbiome. Both species also are among the most important and problematic, opportunistic nosocomial pathogens. Surprisingly, these two species antagonize each other's virulence in both nematode infection and in vitro biofilm models. We report here the identification of the E. faecalis bacteriocin, EntV, produced from the entV (ef1097) locus, as both necessary and sufficient for the reduction of C...

Antimicrobial prescriptions in neonatal intensive care units (NICUs) represent a point of concern for the emergence of MDROs and for morbidity associated with prolonged antibiotic exposure (e.g., invasive candidiasis, necrotizing enterocolitis, and late-onset sepsis). Antimicrobial stewardship programs (ASPs) have shown to be a valuable tool for the prevention of resistance with the goals of optimizing clinical outcomes while decreasing unnecessary prescribing. The most frequent ASP strategies include the correct collection and interpretation of microbiological specimens, prescription of the narrowest-spectrum antibiotic appropriate for a particular case, and de-escalation or discontinuation of therapy in defined situations...

Fluconazole (FLC) is the drug of choice when it comes to treat fungal infections such as invasive candidiasis in humans. However, the widespread use of FLC has resulted in the development of resistance to this drug in various fungal strains and, simultaneously has occasioned the need for new antifungal agents. Herein, we report the synthesis of 27 new FLC derivatives along with their antifungal activity against a panel of 13 clinically relevant fungal strains. We also explore their toxicity against mammalian cells, their hemolytic activity, as well as their mechanism of action...

Testing for Candida albicans germ-tube antibody IFA IgG assay (CAGTA) is used to detect invasive candidiasis infection. However, most suitable assays lack automation and rapid single-sample testing. The CAGTA assay was adapted in an automatic monotest system (invasive candidiasis [CAGTA] VirClia(®) IgG monotest (VirClia(®)), a chemiluminescence assay with ready-to-use reagents that provides a rapid objective result. CAGTA assay was compared with the monotest automatic VirClia(®) assay in order to establish the diagnostic reliability, accuracy, and usefulness of this method...

In Algeria, superficial mycoses are very commonly diagnosed. Deep fungal infections are less often observed. Few data from Algeria are found in the literature. We report for the first time the main causes of these diseases in our country and provide burden estimates. We searched for existing data and estimated the incidence and prevalence of fungal diseases based on the population at risk and available epidemiological data. Demographic data were derived from the Service (Office) of the Statistics (ONES), World Health Organization (WHO), The Joint Nations Programme on HIV/AIDS (UNAIDS) and national published reports...

Invasive fungal disease (IFD) can be caused by a range of pathogens. Conventional diagnosis has the capacity to detect most causes of IFD, but poor performance limits impact. The introduction of non-culture diagnostics, including the detection of (1-3)-β-D-Glucan (BDG), has shown promising performance for the detection of IFD in variety of clinical settings. Recently, the Dynamiker® Fungus (1-3)-β-D-Glucan assay (D-BDG) was released as an IFD diagnostic test. This article describes an evaluation of the D-BDG assay for the diagnosis of invasive aspergillosis (IA), invasive candidiasis (IC) and Pneumocystis pneumonia (PCP) across several high-risk patient cohorts and provides comparative data with the Associates of Cape Cod Fungitell® and BioRad Platelia™ Aspergillus Ag (GM) assays...

Oropharyngeal candidiasis (OPC), caused predominantly by Candida albicans, is a prevalent infection in patients with advanced AIDS, defects in Th17 immunity, and head and neck cancer. A characteristic feature of OPC is fungal invasion of the oral epithelial cells. One mechanism by which C. albicans hyphae can invade oral epithelial cells is by expressing the Als3 and Ssa1 invasins that interact with the epidermal growth factor receptor (EGFR) on epithelial cells and stimulate endocytosis of the organism. However, the signaling pathways that function downstream of EGFR and mediate C...

Phoom Chairatana, Elizabeth M Nolan
Human α-defensin 6 (HD6) is a 32-residue cysteine-rich peptide that contributes to innate immunity by protecting the host at mucosal sites. This peptide is produced in small intestinal Paneth cells, stored as an 81-residue precursor peptide named proHD6 in granules, and released into the lumen. One unusual feature of HD6 is that it lacks the broad-spectrum antimicrobial activity observed for other human α-defensins, including the Paneth cell peptide human α-defensin 5 (HD5). HD6 exhibits unprecedented self-assembly properties, which confer an unusual host-defense function...
