Some Candida albicans isolates from AIDS patients with oropharyngeal candidiasis are becoming resistant to the azole antifungal agent fluconazole after prolonged treatment with this compound. Most of the C. albicans isolates resistant to fluconazole fail to accumulate this antifungal agent, and this has been considered a cause of resistance. This phenomenon was shown to be linked to an increase in the amounts of mRNA of a C. albicans ABC (ATP-binding cassette) transporter gene called CDR1 and of a gene conferring benomyl resistance (BENr), the product of which belongs to the class of major facilitator multidrug efflux transporters (D. Sanglard, K. Kuchler, F. Ischer, J. L. Pagani, M. Monod, and J. Bille, Antimicrob. Agents Chemother. 39:2378-2386, 1995). To analyze the roles of these multidrug transporters in the efflux of azole antifungal agents, we constructed C. albicans mutants with single and double deletion mutations of the corresponding genes. The mutants were tested for their ...

Of the 76 isolates, 33 were identified as Candida albicans while 37 were C. parapsilosis, three were C. tropicalis, and three were identified as C. glabrata. The geometric mean range for MIC (μg/ml) with regard to all isolates was 0.077 to 3 μg/ml for FLU and ITR, and 0.375 to 0.70 μg/ml for propolis. It was shown that propolis had significant antifungal activity against all Candida strains and the MIC range of propolis was determined as 0185 to 3 μg/ml ...
TY - JOUR. T1 - Empirical antifungal therapy in patients with neutropenia and persistent or recurrent fever of unknown origin. AU - Martino, Rodrigo. AU - Viscoli, Claudio. PY - 2006/1. Y1 - 2006/1. N2 - Persistent or recurrent fever of unexplained origin (PFUO) in neutropenic patients receiving antibiotic therapy is commonly treated with empirical antifungal therapy (EAFT). EAFT was established as an adequate management of PFUO around 20 years ago with conventional amphotericin B deoxycholate (c-AmB), despite its high rate of infusional and systemic toxicities. In recent years, EAFT trials for PFUO have used less toxic agents, such as the lipid formulations of AmB, the new azoles, and the echinocandin, caspofungin. In clinical trials, the lipid formulations of AmB [especially liposomal AmB (L-AmB)] provided similar efficacy with lower toxicity but at a much higher cost. Although rarely used in clinical practice, fluconazole is equivalent to c-AmB, provided patients at high risk of Aspergillus ...
In an analysis of approximately 1.4 million pregnancies in Denmark, use of the oral antifungal medication fluconazole during pregnancy was associated with an increased risk of spontaneous abortion compared with risk among unexposed women and women who used a topical antifungal during pregnancy, according to a study in the Jan. 5 issue of JAMA.
Background: Over the past 5 decades, therapeutic options for invasive fungal infections have remained limited and sub-optimal. Recently, novel antifungal agents like caspofungin and voriconazole have been approved for use. These antifungals offer an advancement in antifungal therapy; however, clinical experience with these agents is limited. We therefore sought to examine how these agents are being used and their impact on patient outcomes at an urban medical center. Methods: The charts of the first 15 patients receiving voriconazole and 15 consecutive patients receiving caspofungin were retrospectively identified and reviewed. Data extraction included patient demographics, past medical history, current admission diagnosis, laboratory values, radiology results, microbiology, and antifungal use. Follow up care in outpatient clinics were reviewed for patient outcome and radiological improvements, when available. Results: 11 patients received antifungal treatment with caspofungin, 3 with ...

These findings confirm and extend those reported previously regarding the antifungal activity of ravuconazole (4, 7, 13, 18) and voriconazole (1, 5, 6, 10, 13, 18). Both triazoles were more active in vitro than fluconazole and itraconazole against virtually all of the Candida spp. tested. Although the MICs of ravuconazole and voriconazole for C. albicans and C. glabrata isolates that were resistant to fluconazole and itraconazole (RR phenotype) were also found to be elevated, those isolates that were resistant to fluconazole alone (RS phenotype) and those for which fluconazole MICs were 16 to 32 μg/ml, were susceptible to ≤1 μg of both ravuconazole and voriconazole per ml. As reported by Perea et al. (12), high-level fluconazole-resistant strains of C. albicans commonly display multiple mechanisms of resistance, including overexpression of MDR1 and CDR efflux pumps as well as alterations in the target enzyme and overexpression of the genes encoding the enzyme. Such isolates have been shown ...
In the past, in vitro testing of antifungal agents has been regarded as problematic, but standardized methods have now been developed for Candida spp. and C. neoformans(9). For these methods to be useful, the results should provide a reliable prediction of the response to treatment for humans with infections. In particular, a high MIC should often correlate with therapeutic failure (15). Numerous reports have demonstrated that the ability to predict clinical outcome differs from agent to agent and depends on the patient population studied (5). For instance, high MICs of fluconazole are often predictive of therapeutic failure in human immunodeficiency virus-positive patients with oral candidiasis (12, 16, 17) but do not correlate with the clinical outcome in patients with candidemia (14). The situation with other antifungal agents is even less clear, but a number of investigations have reported that for the amphotericin B MICs for isolates of Candida spp. recovered during prolonged treatment with ...
A standardized broth microdilution method was used to test the antifungal activity of geldanamycin (GA), an inhibitor of heat shock protein 90 (Hsp90), alone or in combination with the antifungal agent fluconazole (FLC) against 32 clinical isolates of Candida spp. In addition, a disk diffusion test was also used to evaluate the antifungal effect of these two drugs against Candida spp. by measuring the inhibition zone diameters. We found that the range of minimal inhibitory concentrations (MICs) for GA alone against Candida spp. was 3.2-12.8 mg/L and the geometric mean of MICs was 6.54 mg/L. In addition, the combination of GA with FLC showed synergistic effects in vitro against 2 FLC-susceptible and 6 FLC-resistant isolates of C. albicans. As for the other isolates, indifference but no antagonism was observed. In the disk diffusion assay, the diameter of inhibition zones for FLC combined with GA against FLC-resistant C. albicans isolates was 30 mm, while no inhibition was observed with FLC alone. ...

Background: Azoles and polyenes are antifungal agents used for treatment and/or prophylaxis of C. albicans infections, and a high increase in antifungal resistance in clinical isolates of C. albicans in HIV/AIDS patients has been reported. Five genetic clades were described among C. albicans isolates using DNA fingerprinting methods (clades I, II, III, SA and NG). Although these clades have been described, little is known about their phenotypic characteristics, and not much is known about antifungal resistance with regard to each of these clades. The widespread use of fluconazole has led to its increased resistance reported world-wide. Resistance to fluconazole can be caused by point mutations in the ERG11 gene or overexpression of this gene, however, not much is known about the contribution of these mutations and over-expression to fluconazole resistance among different clades of C. albicans, and whether mutations or over-expression are clade-related. There is evidence to suggest that ...

New antifungals. Maria Coca, researcher at CRAG and one of the senior authors of the study, explains that "only a few classes of antifungal agents are available today, and even these are not fully effective due to the development of resistance, host toxicity, and undesirable side effects. Many of these compounds do not even comply with the regulations, and therefore they cannot be used. Thus, there is an urgent need to develop novel antifungals, whose properties and mechanisms of action represent improvements on the existing ones, and which can be applied in diverse fields, including crop and postharvest protection, preservation in cosmetics, materials and food, and animal and human health." Cocas research group, in collaboration with the IATAs researcher Jose F. Marcos, aims to develop new antifungal compounds based on the antifungal proteins (AFPs) secreted by filamentous fungi. The problem is that the synthesis of these compounds is extremely complex; hence their exploitation requires ...

Introduction. Many researchers, particularly the ones from countries with a rich biodiversity, have contributed to the detection of new antifungal compounds in medicinal plants. Screening by using in vitro evaluation is a useful tool for the discovery of new potential antifungal agents from natural products such as essential oils and extracts derived from plants (1). Colombia is the second richest country in the world in biodiversity, and its floral diversity is estimated at 40,000 species of vascular plants (2). Although Colombia possesses a rich tradition in the use of medicinal plants, the antifungal activity of medicinal plantsâ derivates has not been deeply studied.. Candidiasis is a common infection of the skin, nails, oral cavity, esophagus, and vagina, caused by yeast of the Candida genus. Systemic yeast infections are a common consequence of immunosuppression, long-term indwelling catheters, and endocrinopathies. Candida albicans is the most common pathogen causing that fungal ...
Voriconazole is an antifungal agent which has been approved for treatment of a broad range of fungal infections, including those caused by Candida species. The authors, from the United Kingdom, the United States of America and New Zealand, analyzed susceptibility data for the yeasts isolated from patients taking part in the voriconazole phase III clinical trials. The aim was to compare the effectiveness of voriconazole with other agents, by studying the yeasts response to these antifungal agents in vitro, and also to check for resistance to voriconazole. The researchers analyzed the effect of itraconazole, fluconazole, amphotericin B and voriconazole versus 1763 yeasts isolated from samples obtained from 472 patients. The yeast cultures obtained were predominantly Candida spp. (97.1%), although there were seven genera and 22 species of yeasts in all. The infections the patients were suffering from arose most commonly from surgery/trauma/burns (37% of patients), haematological malignancy (13%) ...
A fungal infection can range from mild to severe, and can be life threatening, requiring hospitalization and possibly many months of one or more antifungal medications to eliminate the infection. A life threatening fungal infection probably sounds odd to you because the most common fungal infections are of the skin, vagina and mouth, such as athletes foot, jock itch, ringworm, vaginal yeast infections and oral thrush. Skin infections can usually be prevented or cleared up by keeping the area clean and dry. Most are treatable with medications you can buy without a prescription. Sometimes stubborn fungal infections require prescription antifungal medication, so see your health care provider if yours does not clear up with home treatment.
Invasive fungal infections are becoming an increasingly important cause of human mortality and morbidity, particularly for immunocompromised populations. The fungal pathogens Candida albicans, Cryptococcus neoformans, and Aspergillus fumigatus collectively contribute to over 1 million human deaths annually. Hence, the importance of safe and effective antifungal therapeutics for the practice of modern medicine has never been greater. Given that fungi are eukaryotes like their human host, the number of unique molecular targets that can be exploited for drug development remains limited. Only three classes of molecules are currently approved for the treatment of invasive mycoses. The efficacy of these agents is compromised by host toxicity, fungistatic activity, or the emergence of drug resistance in pathogen populations. Here we describe our current arsenal of antifungals and highlight current strategies that are being employed to improve the therapeutic safety and efficacy of these drugs. We discuss state
Using combination antifungal therapy for invasive mold diseases is still a grey area that remains to be supported by robust data and relies heavily on clinician assessment.
RESULTS: In all, 15 (65%) of the 23 centers were adult SCT centers, 7 (31%) were pediatric SCT centers, and 1 center treated both adult and pediatric patients. All centers (23/23) performed both allogeneic and autologous transplants, 20 centers performed non-myeloablative transplants, 8 performed cord blood transplants, and 7 performed unrelated transplants. Primary antifungal prophylaxis was used at all 23 centers during allogeneic transplants, whereas 18 of the 23 centers used it during every autologous transplant and 2 of the 23 centers used it during autologous transplants on a per case basis. The most common drug used for prophylaxis was fluconazole (F) (21/23), followed by itraconazole (I) (3/23), amphotericin-B (2/23), and posaconazole (1/23). Among the 23 centers, 3 reported that for allogenic transplants they changed the antifungal prophylactic in cases of graft versus host disease (GVHD), and 12 of the 23 centers reported that they changed the antifungal prophylactic in case of nearby ...
SCY-078 is an antifungal agent in clinical development for the treatment of fungal infections caused by Candida and Aspergillus species. SCY-078 is a triterpenoid, semi-synthetic derivative of the natural product enfumafungin - a structurally distinct and novel class of glucan synthase inhibitor. SCY-078 combines the well-established activity of glucan synthase inhibitors with the potential flexibility of having IV and oral formulations. By belonging to a chemical class distinct from other antifungals, SCY-078 has shown in vitro and in vivo activity against multi-drug resistant pathogens, including azole- and echinocandin-resistant strains. The U.S. Food and Drug Administration granted Fast Track, Qualified Infectious Disease Product and Orphan Drug Designations for the formulations of SCY-078 for the indications of invasive candidiasis (including candidemia) and invasive aspergillosis..

The posaconazole prescribing information recommends an upfront cyclosporine dosage reduction upon initiation of posaconazole prophylaxis. recommendation might be modified. TEXT Posaconazole is certainly a book triazole with broad-spectrum antifungal activity and a good toxicity profile (4 7 thats currently accepted for principal antifungal prophylaxis in allogeneic bloodstream and marrow transplantation (allo-BMT) recipients with graft-versus-host disease (GVHD) (18). Posaconazole prophylaxis in allo-BMT recipients is generally administered in combination with immunosuppressive drugs for GVHD Wortmannin prophylaxis and/or treatment most commonly cyclosporine (CsA). On the basis of its CYP3A4-inhibitory activity posaconazole increases the exposure to CsA warranting a recommendation for close monitoring. ...
Current antifungal agents in medicine presents high toxicity and collateral effects, targets limited cell constituents and different resistance mechanisms have already been described. In order to identify novel potential antifungal drug targets, two hypothetical Candida albicans genes potentially essential and with singular expression profile have been characterized. The ORF CaYlr339c is conserved among fungal species from Candida and Saccharomyces genus, is transcribed in yeast and hyphae and an approximately 18-kDa protein was identified in hyphae and yeasts C. albicans cell extracts by western blotting. The ORF CaYdr187c is conserved in a few representatives of the Saccharomyces genus, is transcribed only in yeasts and potentially codifies a surface protein. These findings indicate that the selected ORFs are real genes and could be good candidates for the discovery of new functions and the development of new antifungal agents in the future. In an attempt to test the possible role of the ...
Antifungal therapy is an important element of patient management for acute and chronic diseases. Yet, as the global burden of fungal infections rises, treatment choices are constrained due to limited classes of antifungal agents. Furthermore, clinical management of fungal diseases is made even more tenuous by the emergence of antifungal drug resistance. More recently, the evolution of multidrug resistant organisms refractory to several different classes of antifungal agents is alarming. The resistance mechanisms responsible are largely shared by strains displaying inherently reduced susceptibility to specific antifungal agents and strains acquiring resistance during therapy. The principal molecular mechanisms are well characterized and include diminished drug-target interactions through changes in affinity and target abundance, and reduction in the intracellular level of drug through expression of high-capacity efflux pumps and biofilm formation. In some strains, high-level resistance occurs through a
The prevention and treatment of invasive fungal infections is being improved by the relatively recent introduction of new antifungal agents. While some of these agents offer better efficacy, others are proving their value more in improved tolerability, said John R. 1
There is a growing need for new antifungal therapies like isavuconazole because serious fungal infections caused by Aspergillus and other molds are on the rise due to the increasing numbers of immunosuppressed patients, including those with active cancer. These infections are associated with high morbidity and mortality. If approved, isavuconazole has the potential to be an important new option for the treatment of these life-threatening fungal infections," says Andrew Ullman of Julius Maximilians University in Wuerzburg, Germany, one of the researchers presenting data ...
Antifungal creams are part of the treatment plan for fungal infections in dogs. These remedies are applied topically, on the skin. Most of them can also be used in more sensitive areas of the body. An antifungal cream relieves the uncomfortable symptoms and destroys the fungi.. The disadvantage of using antifungal creams is that the dog might lick them off the skin before the medication can produce any effect. You should try to prevent this after applying the cream by bandaging the skin or making sure you massage the cream into the skin.. Generally antifungal creams designed for human use can also be used in dogs. Before starting any type of treatment it is best to consult your veterinarian and let him decide on the most appropriate product for your dogs infection. The most common active substances of antifungal creams are:. ...

Roy et al conducted a study of the role of OTC vaginal pH self-test products in improving the use of antifungal medications.6 The studys objectives were to: 1) assess patients ability to understand how to use a vaginal pH self-test product to diagnose vaginitis; 2) determine whether there is similarity between vaginal pH readings by patients and by HCPs; and 3) decide whether a vaginal pH self-test product can help reduce the inappropriate use of OTC antifungal medications. The patients were of varied backgrounds, educational levels (range, 0 years of formal education to graduate school), and ages (range, 17 to 73 years). Of the 151 women studied, 33 (22%) were asymptomatic and 118 (78%) were symptomatic. Of the 118 symptomatic patients, 96 were premenopausal, were not pregnant, and had a uterus in situ. Since a final diagnosis was not supplied by the HCP for eight patients, 88 symptomatic patients were used for analysis. A vaginal pH level exceeding 4.5 was considered to be a positive finding ...
Invasive aspergillosis (IA) is a devastating opportunistic infection and its treatment constitutes a considerable burden for the health care system. Immunocompromised patients are at an increased risk for IA, which is mainly caused by the species Aspergillus fumigatus. An early and reliable diagnosis is required to initiate the appropriate antifungal therapy. However, diagnostic sensitivity and accuracy still needs to be improved, which can be achieved at least partly by the definition of new biomarkers. Besides the direct detection of the pathogen by the current diagnostic methods, the analysis of the host response is a promising strategy toward this aim. Following this approach, we sought to identify new biomarkers for IA. For this purpose, we analyzed gene expression profiles of hematological patients and compared profiles of patients suffering from IA with non-IA patients. Based on microarray data, we applied a comprehensive feature selection using a random forest classifier. We identified ...
JUNE 25TH 2013 , Manchester, UK, F2G Limited, a privately-held antifungal drug discovery and development company and The University of Manchester, today announced the commencement of a 6.1 million euro EU -funded project to discover and develop novel antifungal drugs to treat serious, life-threatening fungal infections.

This project aims to develop novel agents with completely new ways of acting in order to combat the increasing tide of drug resistant fungal infections. NOFUN will use F2Gs discovery assets and the Universitys fungal genomics platforms in addition to the drug development and characterisation expertise ...
Trailing endpoints occasionally complicate the interpretation of antimicrobial susceptibility testing of both bacteria and fungi. Early studies in bacterial susceptibility testing made note of the phenomenon, especially in the testing of sulfonamide compounds (2). Both broth and agar methods have been associated with trailing endpoints (2, 4, 5). The effect was attributed to the bacteriostatic action of the sulfonamides, with several generations being required before significant growth inhibition occurs. In addition, these isolates were not felt to be clinically resistant, despite high MICs. In one study, in vivo testing in mice showed no difference between susceptible isolates and those for which trailing endpoints were observed (6).. Antifungal susceptibility testing has made considerable progress in recent years. Specifically, the NCCLS methods (broth macro- and microdilution) have been shown to be reproducible and clinically useful, with good in vitro-in vivo correlation in the setting of ...
Anidulafungin is an antifungal medication that fights infections caused by fungus. Anidulafungin treats candida (yeast) infections in the blood, or in the stomach or esophagus. Anidulafungin may also be used for purposes not listed in this medication guide.
Invasive fungal diseases have increased many fold over the past 50 years. Current treatment regimens typically require prolonged administration of antifungal medications that can have significant toxicity. Moreover, our present potent antifungal armamentarium fails to eradicate fungal pathogens from certain compromised hosts. Additionally, invasive fungal diseases continue to have unacceptably high mortality rates. A growing body of work has focused on the utility of vaccines and/or immunotherapy as a powerful tool in combating mycoses, either for the active treatment, as an adjuvant, or in the prevention of specific fungal pathogens. This Research Topic will detail the exciting progress in developing vaccines and immunotherapy for fungi.

Invasive fungal infections have become an important cause of mortality in immunocompromised and severely ill patients, in both the developing world and western countries. The mortality rates from these infections can reach 50% or more. Candida albicans is the most common human fungal pathogen, causing mucosal infections and systemic invasive disease. A key feature of fungi is that they are eukaryotic organisms closely related to their human host, posing a problem for the design of safe, but effective antifungal therapy. Excitingly, we have identified a new fungal-specific factor not conserved in humans, Taf14, which represents a promising antifungal drug target. Current studies suggest that Taf14 plays a role in transcription and DNA repair, and potentially impacts on two key virulence attributes in C. albicans, adherence and filamentous growth. However, the molecular functions of this factor are unknown. Targeting Taf14 or the process it regulates would represent a completely novel approach to ...

Recently, the scientific interest into biological properties of EO has been increasing. In particular, a large number of papers have been published on the EO antimicrobial activity, but many of them focused on the activity of EO in solution against bacteria and yeasts while little investigation on the effect of EO in vapour state has been performed (Inouye et al. 2000, 2001a, 2001b). In the present study, the antifungal activity of seven EO were compared by microdilution and VC methods against dermatophytes and other moulds. Quantification of the EO antimicrobial activity appears to be influenced by the test method used, as evidenced by the differences between the MICs obtained by BM and VC methods. The results revealed that five of the seven EO tested were stronger inhibitory in vapour state than in liquid phase. The efficacy of EO in vapour state was probably attributable to the direct deposition of EO on lipophilic fungal mycelia together with an indirect effect via adsorption through the ...
New research indicates that the oral antifungal drug itraconazole, most commonly used to treat nail fungus, may keep prostate cancer from worsening
An FDA-approved drug used for preventing recurrence of breast cancer shows promise in fighting life-threatening fungal infections common in immune-compromised patients, such as infants born prematurely and patients with cancer. Some scientists suspected that tamoxifen has antifungal properties; now new research from the University of Rochester Medical Center shows that it actually kills fungus cells and stops them from causing disease.. "Its still early, but if tamoxifen, or molecules like it, turns out to be an effective treatment against serious fungal infections, itll be a welcome addition to our arsenal," said Damian Krysan, M.D., Ph.D., author of the research recently published in the journal Antimicrobial Agents and Chemotherapy and assistant professor of Pediatrics at the University of Rochester Medical Center .. While serious fungal infections are generally isolated to patients with cancer, patients in intensive care units, patients with HIV or patients taking immune-suppression ...
