There is an emerging necessity for improved therapies against Candida-related infections, with significant implications for global healthcare. Current antifungal agents, limited in number, target specific pathways, but resistance remains a concern. Flucytosine (5FC) exhibits antifungal activity, particularly against Candida. However, monotherapy efficacy is limited, necessitating combination treatments. Herein, we report PEGylated squalene-based nanocarriers for 5FC loading, aiming to enhance its monotherapy efficacy against Candida strains. The loading of 5FC within micelles was achieved using the ultrasound-assisted solvent evaporation method. The 5FC-loaded micelles, together with non-loaded micelles, were thoroughly characterized and analyzed. STEM and DLS analysis confirmed the core-shell morphology with nanometric dimensions along with improved colloidal stability. The quantification of drug loading efficiency and drug loading capacity was calculated using the UV-Vis technique. The in vitro drug-release studies in simulated physiological conditions showed sustained release within 48 hours. Moreover, the release kinetics calculated using mathematical models showed a Fickian diffusion drug release mechanism in simulated physiological conditions with a slower diffusion rate. The in vitro antifungal activity was tested on Candida albicans, Candida glabrata, and Candida parapsilosis. The results showed improved antifungal activity for the nanotherapeutic and unchanged in vitro toxicity toward normal cells, suggesting promising advancements in 5FC therapy.

UNASSIGNED: This safety analysis investigates treatment-emergent mucosal/cutaneous Candida infections in patients treated with ixekizumab (IXE), an anti-interleukin-17A monoclonal antibody, across the approved indications: psoriasis (PsO), psoriatic arthritis (PsA), and axial spondyloarthritis (axSpA).
UNASSIGNED: Safety data were pooled from 25 clinical studies. Incidence rates (IRs) are expressed as per 100 patient-years (PY), using the entire duration of exposure.
UNASSIGNED: Candida infections had an IR of 1.9 per 100 PY in patients with PsO (N = 6892;total PY = 18025.7), 2.0 per 100 PY in patients with PsA (N = 1401; total PY = 2247.7), and 1.2 per 100 PY in patients with axSpA (N = 932;total PY = 2097.7). The majority of treatment-emergent Candida infections were: (i) experienced only once by patients (IR = 1.3;IR = 1.6;IR = 1.0), (ii) mild/moderate in severity (IR = 0.8/0.9;IR = 1.5/0.4;IR = 0.8/0.5) as opposed to severe (IR = 0.0; IR = 0.0; IR = 0.0), (iii) oral Candida or genital Candida (IR = 0.9/0.6;IR = 1.0/0.7;IR = 0.4/0.6), (iv) marked as recovered/resolved during the studies (89.3%;93.8%;90.3%), (v) not leading to IXE discontinuation (0.0%;0.0%;0.1% discontinued), (vi) managed with topical (34.7%;22.2%;11.5%) or no anti-fungal medications (63.5%;77.8%;80.8%) as opposed to systemic therapies (1.5%;0.0%;7.7%), (vii) typically resolved before next visit.
UNASSIGNED: This integrated safety analysis shows that the risk of developing Candida infections is low with IXE, and the severity is mild-to-moderate in most instances across the approved IXE indications.
UNASSIGNED: A comprehensive list of the clinical trials and their registration numbers is reported in Table S1 of the supplemental material.
Ixekizumab(IXE) is a drug approved for the treatment of psoriasis, psoriatic arthritis,and axial spondyloarthritis. IXE belongs to the class of molecules that block aprotein called interleukin-17A. Since interleukin-17A is involved in the defenseagainst fungi, the clinical use of this class of drug has the potential to increasethe risk of developing fungal infections, such as Candida infections.Therefore, researcherscollected safety data from 25 clinical studies comprising 9225 adult patientstreated with IXE: 6892 with psoriasis, 1401 with psoriatic arthritis, and 932with axial spondyloarthritis. Researchers looked at the rate of new cases of Candidainfections, the so-called incidence rate, and found that 1.9 per 100patient-years experienced at least 1 Candida infection in the psoriasis group, 2.0per 100 patient-years in the psoriatic arthritis group, and 1.2 per 100patient-years in the axial spondyloarthritis group.Acrossindications, the majority of Candida infections (i) were experienced only once by patients, (ii) were mild or moderate in severity, (iii) involved infections caused by superficial skin fungus in themouth or genitals, (iv) wereconsidered recovered/resolved during the studies, (v) did not lead to IXE discontinuation, (vi) were managed with topical anti-fungal medications or nomedications, and (vii) typicallyresolved before next visit.In conclusion,this safety analysis shows that the risk of developing Candida infections islow with IXE, and the severity is mild-to-moderate in most instances across theapproved IXE indications.

BACKGROUND: Candida auris is an emerging multidrug-resistant fungus associated with catheter-related bloodstream infections. In vitro efficacy of chlorhexidine (CHX) and CHX-silver sulfadiazine-impregnated (CHX-S) antimicrobial central venous catheters (CVCs) against C auris was investigated.
METHODS: Minimum inhibitory and bactericidal CHX concentrations were determined against 19 C auris isolates. To assess extraluminal efficacy, segments from CVCs impregnated externally (CHX-S1) and both externally and internally (CHX-S2) were plasma-conditioned for 1- and 6-day, and to assess intraluminal efficacy, CHX-S2 CVCs were preconditioned with saline-lock for 6days, followed by 24-hour C auris inoculation and microbial adherence determination on impregnated and nonimpregnated CVCs.
RESULTS: CHX inhibited all C auris isolates with minimum inhibitory and bactericidal concentrations range of 8 to 128 μg/mL. C auris adherence was reduced on CHX-S1 and CHX-S2 extraluminally by 100% on day 1, 86.96% to 100% on day 7, and intraluminally on CHX-S2 by 56.86% to 90.52% on day 7.
CONCLUSIONS: CHX and CHX-S CVC performance against C auris observed in this study is consistent with antimicrobial benefits observed in prior preclinical and randomized controlled clinical studies.
CONCLUSIONS: CHX showed strong inhibitory and cidal effects on C auris. CHX-S CVCs proved highly efficacious against this pathogen under in vitro conditions. Additional studies, however, are required to confirm clinical benefit.

The incidence of Candida infections has increased in the last decade, posing a serious threat to public health. Appropriately facing this challenge requires precise epidemiological data on species and antimicrobial resistance incidence, but many countries lack appropriate surveillance programs. This study aims to bridge this gap for Morocco by identifying and phenotyping a year-long collection of clinical isolates (n = 93) from four clinics in Tetouan. We compared the current standard in species identification with molecular methods and assessed susceptibility to fluconazole and anidulafungin. Our results identified limitations in currently used diagnostics approaches, and revealed that C. albicans ranks as the most prevalent species with 60 strains (64.52%), followed by C. glabrata with 14 (15.05%), C. parapsilosis with 6 (6.45%), and C. tropicalis with 4 (4.30%). In addition, we report the first identification of C. metapsilosis in Morocco. Susceptibility results for fluconazole revealed that some isolates were approaching MICs resistance breakpoints in C. albicans (2), and C. glabrata (1). Our study also identified anidulafungin resistant strains in C. albicans (1), C. tropicalis (1), and C. krusei (2), rendering the two strains from the latter species multidrug-resistant due to their innate resistance to fluconazole. These results raise concerns about species identification and antifungal resistance in Morocco and highlight the urgent need for more accurate methods and preventive strategies to combat fungal infections in the country.

Candida albicans is a commensal fungus that infects the humans and becomes an opportunistic pathogen particularly in immuno-compromised patients. Among the Candida genus, yeast C. albicans is the most frequently incriminated species and is responsible for nearly 50-90% of human candidiasis, with vulvovaginal candidiasis alone, affecting about 75% of the women worldwide. One of the significant virulence traits in C. albicans is its tendency to alternate between the yeast and hyphae morphotypes, accounting for the development of multi-drug resistance in them. Thus, a thorough comprehension of the decision points and genes controlling this transition is necessary, to understand the pathogenicity of this, naturally occurring, pernicious fungus. Additionally, the formation of C. albicans biofilm is yet another pathogenesis trait and a paramount cause of invasive candidiasis. Since 1980 and in 90 s, wide spread use of immune-suppressing therapies and over prescription of fluconazole, a drug used to treat chronic fungal infections, triggered the emergence of novel anti-fungal drug development. Thus, this review thoroughly elucidates the diseases associated with C. albicans infection as well as the anti-fungal resistance mechanism associated with them and identifies the emerging therapeutic agents, along with a rigorous discussion regarding the future strategies that can possibly be adopted for the cure of this deleterious pathogen.

Candida albicans, a ubiquitous opportunistic fungal pathogen, plays a pivotal role in human health and disease. As a commensal organism, it normally resides harmlessly within the human microbiota. However, under certain conditions, C. albicans can transition into a pathogenic state, leading to various infections collectively known as candidiasis. With the increasing prevalence of immunocompromised individuals and the widespread use of invasive medical procedures, candidiasis has become a significant public health concern. The emergence of drug-resistant strains further complicates treatment options, highlighting the urgent need for alternative therapeutic strategies. Antifungal peptides (AFPs) have gained considerable attention as potential candidates for combating Candida spp. infections. These naturally occurring peptides possess broad-spectrum antimicrobial activity, including specific efficacy against C. albicans. AFPs exhibit several advantageous properties, such as rapid killing kinetics, low propensity for resistance development, and diverse mechanisms of action, making them promising alternatives to conventional antifungal agents. In recent years, extensive research has focused on discovering and developing novel AFPs with improved efficacy and selectivity against Candida species. Advances in biotechnology and synthetic peptide design have enabled the modification and optimization of natural peptides, enhancing their stability, bioavailability, and therapeutic potential. Nevertheless, several challenges must be addressed before AFPs can be widely implemented in clinical practice. These include optimizing peptide stability, enhancing delivery methods, overcoming potential toxicity concerns, and conducting comprehensive preclinical and clinical studies. This commentary presents a short overview of candidemia and AFP; articles and reviews published in the last 10 years were searched on The National Library of Medicine (National Center for Biotechnology Information-NIH-PubMed). The terms used were C. albicans infections, antimicrobial peptides, antifungal peptides, antifungal peptides mechanisms of action, candidemia treatments and guidelines, synthetic peptides and their challenges, and antimicrobial peptides in clinical trials as the main ones. Older publications were cited if they brought some relevant concept or helped to bring a perspective into our narrative. Articles older than 20 years and those that appeared in PubMed but did not match our goal to bring updated information about using antifungal peptides as an alternative to C. albicans infections were not considered.

Candida species cause life-threatening infections with high morbidity and mortality rates and their resistance to conventional therapy is closely linked to biofilm formation. Thus, the development of new approaches to study Candida biofilms and the identification of novel therapeutic strategies could yield improved clinical outcomes. In the current study, we have set up an impedance-based in vitro system to study Candida spp. biofilms in real-time and to evaluate their sensitivity to two conventional antifungal groups used in clinical practice - azoles and echinocandins. Both fluconazole and voriconazole were unable to inhibit biofilm formation in most strains tested, while echinocandins showed biofilm inhibitory capacity at relatively low concentrations (starting from 0.625 mg/L). However, assays performed on 24 h Candida albicans and C. glabrata biofilms revealed that micafungin and caspofungin failed to eradicate mature biofilms at all tested concentrations, evidencing that once formed, Candida spp. biofilms are extremely difficult to eliminate using currently available antifungals. We then evaluated the antifungal and anti-biofilm effect of andrographolide, a natural compound isolated from the plant Andrographis paniculata with known antibiofilm activity on Gram-positive and Gram-negative bacteria. Optical density measures, impedance evaluation, CFU counts, and electron microscopy data showed that andrographolide strongly inhibits planktonic Candida spp. growth and halts Candida spp. biofilm formation in a dose-dependent manner in all tested strains. Moreover, andrographolide was capable of eliminating mature biofilms and viable cell numbers by up to 99.9% in the C. albicans and C. glabrata strains tested, suggesting its potential as a new approach to treat multi-resistant Candida spp. biofilm-related infections.

Opportunistic fungal infections by Candida species arise among cancer patients due to the weakened immune system following extensive chemotherapy. Prophylaxis with antifungal agents have developed the resistance of Candida spp. to antifungals. Accurate identification of yeasts and susceptibility patterns are main concerns that can directly effect on the treatment of patients.
Over a period of three years, 325 cancer patients suspected to Candida infections were included in the current investigation. The clinical isolates were molecularly identified by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). All strains, were examined for in vitro susceptibility to the amphotericin B, itraconazole, fluconazole, and anidulafungin according to the CLSI M27 document.
Seventy-four cancer patients had Candida infections (22.7%). Candida albicans was the most common species (83.8%). Antifungal susceptibility results indicated that 100% of the Candida isolates were sensitive to amphotericin B; however, 17.6%, 9.4%, and 5.4% of clinical isolates were resistant to anidulafungin, fluconazole, and itraconazole, respectively.
The findings of the present work shows a warning increase in resistance to echinocandins. Since all fluconazole resistance isolates were obtained from candidemia, we recommend amphotericin B as the first line therapy for this potentially fatal infection.

Auto-brewery syndrome (ABS) occurs when the gastrointestinal tract produces excessive endogenous ethanol. This article examines various aspects of ABS such as its epidemiology, underlying etiology, diagnostic difficulties, management strategies, and social implications. By synthesizing the existing medical literature, we hope to identify understanding gaps, pave the way for further research, and ultimately improve detection, treatment, and awareness. The databases we used are PubMed, PubMed Central, and Google Scholar. We carefully screened all published articles from inception till date and narrowed down 24 relevant articles. We at Richmond University Medical Center and Mount Sinai are one of the leading medical centers for diagnosing and treating this rare condition in the United States.

Superficial cutaneous and mucosal Candida infections are common and widely affect both the immunocompromised as well as the immunocompetent populations. Common infections may include Candida paronychia, cutaneous candidiasis, oral candidiasis, vulvovaginal candidiasis, and Candida onychomycosis. Although C albicans has been considered to be the most common pathogen, other Candida species have emerged as potential causes of certain infections. Currently, a variety of antifungal agents is available to treat these infections. They include fluconazole, ketoconazole, and itraconazole. These agents have been widely used to treat fungal infections, including superficial and systemic candidiasis. However, some concerns exist regarding safety associated with longterm use of ketoconazole, and emerging issues of Candida resistance to fluconazole in some patient subsets have been reported. Itraconazole has proven efficacy in treating cutaneous and mucosal Candida infections. Additionally, studies have demonstrated that itraconazole may have increased efficacy and an excellent safety profile when administered in a pulse-dose, or intermittent fashion, for superficial mycotic infections. Itraconazole is an effective agent that warrants consideration when selecting treatment for Candida infections.
