Candida auris has emerged as a significant clinical entity due to its ability to cause outbreaks within the healthcare setting. A key feature of its nosocomial lifestyle is its ability to transfer between patients, yet little is known about the mechanisms behind this. A panel of C. auris clinical isolates was screened for their planktonic and sessile susceptibilities to skin disinfection challenge using povidone iodine, chlorhexidine and hydrogen peroxide. C. auris biofilms displayed increased tolerance to these strategies compared to planktonic cells...

BACKGROUND: Superficial fungal infections of the skin, nails and hair are common with Trichophyton rubrum and Candida albicans being the main pathogens. Yet, in some patients, mycological cultures show growth of more than one fungal agent in the same anatomical region. OBJECTIVE: This study analyses prevalence, frequency and fungal agents found in superficial fungal mixed infections and discusses consequences for diagnostics and treatment. METHODS: Mycological data obtained between January 2006 to December 2015 from clinical specimens from a total cohort of 7733 patients with suspected fungal infections were retrospectively analysed...

Interactions in the airway ecology of cystic fibrosis may alter organism persistence and clinical outcomes. Better understanding of such interactions could guide clinical decisions. We fitted logistic regression models using generalized estimating equations to longitudinal two-year patient cohorts in the Cystic Fibrosis Foundation Patient Registry, 2003-2011 to study associations between airway organisms present in each calendar year and their presence in the subsequent year. Models were adjusted for clinical characteristics and multiple observations per patient and tested for sensitivity to cystic fibrosis-specific treatments...

Photodynamic therapy (PDT) is a process that combines a photosensitizing drug and light and promotes phototoxic responses in target cells, mainly via oxidative damage. Antifungal photodynamic therapy has been successfully employed against Candida species, dermatophytes, and deep mycoses. We present a case of a cutaneous granuloma caused by C. albicans treated with 5-aminolevulinic acid (ALA)-PDT. A 64-year-old man presented with two plaques on his right hand and wrist for 2 years. The diagnosis was made based on histopathology, mycology, and molecular identification of paraffin-embedded tissues...

Fungal pathogens are a growing threat to public health. As human immunodeficiency becomes increasingly common, fungal infections are becoming more prevalent. The use of antifungal agents for prophylaxis and treatment of fungal infections has favored the emergence of previously rare or unidentified species of drug-resistant fungal pathogens, including several Candida and Cryptococcus species, as well as mold pathogens. As these new and increasingly drug-resistant fungal pathogens continue to emerge, novel strategies for rapid identification and treatment are necessary to combat these life-threatening infections...

BACKGROUND: Neonatal candidiasis causes significant morbidity and mortality in high risk infants. The micafungin dosage regimen of 10 mg/kg established for the treatment of neonatal candidiasis is based on a laboratory animal model of neonatal hematogenous Candida meningoencephalitis and pharmacokinetic (PK)-pharmacodynamic (PD) bridging studies. However, little is known about the how these PK-PD data translate clinically. METHODS: Micafungin plasma concentrations from infants were used to construct a population PK model using Pmetrics software...

Purpose: A significant increase in the incidence of fungal infections and drug resistance has been observed in the past decades due to limited availability of broad-spectrum antifungal drugs. Nanomedicines have shown significant antimicrobial potential against various drug-resistant microbes. Silver nanoparticles (AgNps) are known for their antimicrobial properties and lower host toxicity; however, for clinical applications, evaluation of their impact at cellular and molecular levels is essential...

Candidemia is a bloodstream fungal infection caused by Candida species and is most commonly observed in hospitalized patients. Even with proper antifungal drug treatment, mortality rates remain high at 40-50%. Therefore, prophylactic or preemptive antifungal medications are currently recommended in order to prevent infections in high-risk patients. Moreover, the majority of women experience at least one episode of vulvovaginal candidiasis (VVC) throughout their lifetime and many of them suffer from recurrent VVC (RVVC) with frequent relapses for the rest of their lives...

During the last two decades incidences of fungal infections dramatically increased and the often accompanying failure of available antifungal therapies represents a substantial clinical problem. The urgent need for novel antimycotics called particular attention to the study of natural products. The genus Hypericum includes many species that are used in the traditional medicine to treat pathological states like inflammations and infections caused by fungi. However, despite the diffused use of Hypericum -based products the antifungal potential of the genus is still poorly investigated...

Progress in diagnosis and treatment of endocrine diseases has made pregnancy possible for women with endocrinopathies, including Cushing's syndrome (CS). The risk of maternal-fetal complications in patients who are not biochemically controlled, however, is substantial. Therefore, the surgical and/or medical control of hypercortisolism is mandatory prior to conceiving. A diagnosis of de novo CS during gestation is difficult due to changes in the hypothalamic-pituitary-adrenal axis during pregnancy, which may lead to some clinical features suggestive of CS along with abnormal laboratory tests...

SCY-078, the first in a new class of β 1,3-glucan synthesis inhibitors, is being developed as an oral and intravenous antifungal treatment for Candida and Aspergillus species fungal infections. In vitro, studies indicated SCY-078 is an inhibitor of cytochrome P450 (CYP) 2C8 with markedly lower effect over other CYP isozymes. To examine clinically relevant effects of the potential interaction with SCY-078, this phase 1, open-label, 2-period crossover study evaluated the pharmacokinetic parameters of rosiglitazone, a sensitive substrate of CYP2C8 metabolism, in the absence and presence of SCY-078 dosed to therapeutically relevant SCY-078 concentration exposure after repeat dosing...

Many infectious diseases disproportionately affect people in the developing world. Cryptococcal meningitis is one of the most common mycoses in HIV-AIDS patients, with the highest burden of disease in sub-Saharan Africa. Current best treatment regimens still result in unacceptably high mortality rates, and more effective antifungal agents are needed urgently. Drug development is hampered by the difficulty of developing effective antifungal agents that are not also toxic to human cells, and by a reluctance among pharmaceutical companies to invest in drugs that cannot guarantee a high financial return...

Introduction Fungal infection of the peritoneum has become more common in recent years, the most common cause of which is Candida. Candida peritonitis is considered as a severe disease and is regarded as an independent risk factor for mortality in postoperative peritonitis. This study was planned to find out the clinical significance of Candida isolation on the outcome of the patients with peritonitis in terms of morbidity and mortality. Methods This prospective study included consecutive patients admitted and operated for secondary peritonitis over a two-year period in a tertiary care hospital in South India...

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...
