RESUMEN
Candida species, commensal residents of human skin, are recognized as the cause of cutaneous candidiasis across various body surfaces. Individuals with weakened immune systems, particularly those with immunosuppressive conditions, are significantly more susceptible to this infection. Diabetes mellitus, a major metabolic disorder, has emerged as a critical factor inducing immunosuppression, thereby facilitating Candida colonization and subsequent skin infections. This comprehensive review examines the prevalence of different types of Candida albicans-induced cutaneous candidiasis in diabetic patients. It explores the underlying mechanisms of pathogenicity and offers insights into recommended preventive measures and treatment strategies. Diabetes notably increases vulnerability to oral and oesophageal candidiasis. Additionally, it can precipitate vulvovaginal candidiasis in females, Candida balanitis in males, and diaper candidiasis in young children with diabetes. Diabetic individuals may also experience candidal infections on their nails, hands and feet. Notably, diabetes appears to be a risk factor for intertrigo syndrome in obese individuals and periodontal disorders in denture wearers. In conclusion, the intricate relationship between diabetes and cutaneous candidiasis necessitates a comprehensive understanding to strategize effective management planning. Further investigation and interdisciplinary collaborative efforts are crucial to address this multifaceted challenge and uncover novel approaches for the treatment, management and prevention of both health conditions, including the development of safer and more effective antifungal agents.

The current research was aimed to synthesize a phytomolecule, naringenin (NRG)-mediated silver nanoparticles (NRG-SNPs) to study their antifungal potential against Candida albicans (C. albicans) and Candida glabrata (C. glabrata). The NRG-SNPs were synthesized by using NRG as a reducing agent. The synthesis of NRG-SNPs was confirmed by a color change and surface plasmon resonance (SPR) peak at 425 nm. Furthermore, the NRG-SNPs were analyzed for size, PDI, and zeta potential, which were found to be 35 ± 0.21 nm, 0.19 ± 0.03, and 17.73 ± 0.92 mV, respectively. In silico results demonstrated that NRG had a strong affinity towards the sterol 14α-demethylase. The docking with ceramide revealed the skin permeation efficiency of the NRG-SNPs. Next, the NRG-SNPs were loaded into the topical dermal dosage form (NRG-SNPs-TDDF) by formulating a gel using Carbopol Ultrez 10 NF. The MIC50 of NRG solution and TSC-SNPs against C. albicans was found to be 50 µg/mL and 4.8 µg/mL, respectively, significantly (P < 0.05) higher than 0.3625 µg/mL of NRG-SNPs-TDDF. Correspondingly, MIC50 results were calculated against C. glabrata and the results of NRG, TSC-SNPs, NRG-SNPs-TDDF, and miconazole nitrate were found to be 50 µg/mL, 9.6 µg/mL, 0.3625 µg/mL, and 3-µg/mL, respectively. Interestingly, MIC50 of NRG-SNPs-TDDF was significantly (P < 0.05) lower than MIC50 of miconazole nitrate against C. glabrata. The FICI (fractional inhibitory concentration index) value against both the C. albicans and C. glabrata was found to be 0.016 and 0.011, respectively, which indicated the synergistic antifungal activity of NRG-SNPs-TDDF. Thus, NRG-SNPs-TDDF warrants further in depth in vivo study under a set of stringent parameters for translating in to a clinically viable antifungal product.

Congenital systemic candidiasis is a rare disease observed in both full-term and preterm infants. It can occur with or without congenital cutaneous candidiasis (CCC) and to date, only a few cases have been reported in the literature. We report here, a case of a full-term newborn who presented with diffuse skin eruptions at birth. Blood, urine, and skin scraping cultures were positive and the aetiological agent was Candida albicans. After six weeks of anti-fungal treatment with fluconazole, the newborn was cured. Early diagnosis is crucial in preventing complications caused by candidiasis in newborns.

Candida infection is seen in patients with weak or disrupted host responses. Cutaneous candidiasis typically affects the intertriginous areas and presents with a red plaque surrounded by satellite lesions. Diagnosis of cutaneous candidiasis is made by visual inspection followed by potassium hydroxide normal saline microscopic preparation (wet mount) and polymerase chain reaction identification or culture of fungal organism. The following case describes a 38-year-old patient with limited mobility who presented with a peri sacral lesion that was first assumed to be a decubitus ulcer by nursing facility staff, but proved to be a cutaneous infection by Candida tropicalis, a less common Candida species. The unusual location as well as the characteristic C. tropicalis micro- and macroscopic appearance are described which ultimately led to the diagnosis of a cutaneous fungal infection in an otherwise immunocompetent individual that was resolved with fluconazole therapy. Our case report emphasizes the need for early diagnosis of cutaneous lesions in patients with limited mobility in consideration that not all Candida species thrive in similar environments and can present in unusual locations of the human body. Although rare, C. tropicalis could be found in this vulnerable population.

Candidiasis is an acute or subacute fungal infection caused by fungi that belongs to candida genus, with Candida albicansbeing the most frequent causative agent. Candida kefyr is a rare cause of candidiasis which has been reported in systemic candidiasis and deep infections. However, to date, it has never been reported as a cause in dermatophytosis. We report a case of candidiasis caused by Candida kefyr in a 72-year-old woman with a chief complaint of pruritic erythematous rash on the back from one day prior to admission. Diagnosis was established based on clinical features, direct microscopic examination with 10% potassium hydroxide solution, gram staining. The fungal species was determined by carbohydrate fermentation test which showed a positive result for Candida kefyr. The patient was treated with miconazole cream and fusidic cream and showed significant clinical improvement.

Invasive fungal infections remain a challenge due to lack of effective antifungal agents and serious drug resistance. Discovery of antifungal agents with novel antifungal mechanism is important and urgent. Previously, we designed the first CYP51/HDAC dual inhibitors with potent activity against resistant Candida albicans infections. To better understand the antifungal spectrum and synergistic mechanism, herein new CYP51/HDAC dual inhibitors were designed which showed potent in vitro and in vivo antifungal activity against C. neoformans and C. tropicalis infections. Antifungal mechanism studies revealed that the CYP51/HDAC dual inhibitors acted by inhibiting various virulence factors of C. tropicalis and C. neoformans and down-regulating resistance-associated genes. This study highlights the potential of CYP51/HDAC dual inhibitors as a promising strategy for the discovery of novel broad-spectrum antifungal agents.

Congenital cutaneous candidiasis is an infrequent invasive fungal infection that usually appears in the first days of life. Extremely low birth weight infants are the most frequently affected. Classic presentation includes diffuse extensive erythematous rash with papules, plaques, pustules and vesicles, which later undergoes desquamation. Systemic dissemination is common in extremely low birth weight infants. Blood, urine and cerebrospinal fluid evaluation should be included in the initial assessment. Early and prolonged treatment has been associated with decreased mortality. We report the case of congenital cutaneous candidiasis in a preterm infant. Early skin lesion recognition allowed establishing adequate treatment in the first hours of life.

Introduction: Macrophage expressed gene 1 (MPEG1) is highly expressed in macrophages and other phagocytes. The gene encodes a bactericidal pore-forming protein, dubbed Perforin-2. Structural-, animal-, and cell-based studies have established that perforin-2 facilitates the destruction of phagocytosed microbes upon its activation within acidic phagosomes. Relative to wild-type controls, Mpeg1 knockout mice suffer significantly higher mortality rates when challenged with gram-negative or -positive pathogens. Only four variants of MPEG1 have been functionally characterized, each in association with pulmonary infections. Here we report a new MPEG1 non-sense variant in a patient with the a newly described association with persistent polymicrobial infections of the skin and soft tissue. Case Description: A young adult female patient was evaluated for recurrent abscesses and cellulitis of the breast and demonstrated a heterozygous, rare variant in MPEG1 p.Tyr430*. Multiple courses of broad-spectrum antimicrobials and surgical incision and drainage failed to resolve the infection. Functional studies revealed that the truncation variant resulted in significantly reduced capacity of the patient's phagocytes to kill intracellular bacteria. Patient-derived macrophages responded to interferon gamma (IFN-γ) by significantly increasing the expression of MPEG1. IFN-γ treatment supported perforin-2 dependent bactericidal activity and wound healing. Conclusions: This case expands the phenotype of MPEG1 deficiency to include severe skin and soft tissue infection. We showed that haploinsufficiency of perforin-2 reduced the bactericidal capacity of human phagocytes. Interferon-gamma therapy increases expression of perforin-2, which may compensate for such variants. Thus, treatment with IFN-γ could help prevent infections.

The administration of conventional dosage forms of itraconazole (ITZ) for cutaneous candidiasis treatment is limited by its poor aqueous solubility and the deep location ofCandida albicans(CA) in this disease. In the present work, we developed a nanocrystal (NC) form of ITZ, which was incorporated into dissolving microneedles (MNs) to facilitate skin delivery of ITZ into the infection site. The NCs were prepared by media milling with an ultra-small-scale device using Pluronic®F127 as a stabiliser. The antifungal activity of ITZ was enhanced by NC formulations (MIC value of 2.5 µg/ml), compared to a coarse dispersion of ITZ (MIC value of >2560 µg/ml). The formulation of ITZ into NCs increased dissolution rate by 3-fold. Furthermore, the dissolving MNs containing ITZ-NCs exhibited better dermatokinetic profiles, compared to needle-free patches and conventional creams containing ITZ-NCs. Importantly, the antifungal activity in anex vivocandidiasis infection model exhibited that the CA viability declined by up to 100% after 48 h of administration. These studies have verified the concept that the incorporation of ITZ-NCs into dissolving MNs can offer an effective approach for cutaneous candidiasis treatment.

BACKGROUND: Cutaneous congenital candidiasis (CCC) is a rare condition consisting of invasive fungal infection of the epidermis and dermis that mostly affects preterm infants. Maternal vaginal candidiasis is present in half of the cases, although the occurrence of invasive candidiasis during pregnancy or peripartum period is exceptional. CASE REPORT: We present the case of a full-term infant that was born by vacuum-assisted vaginal delivery to an apparently healthy 33 year-old woman with no history of intravenous drug use or vaginal candidiasis during pregnancy. The newborn showed a diffuse maculopapular rash with respiratory distress and bilateral interstitial lung infiltrates, requiring nasal continuous positive airway pressure support. Blood cultures obtained from the mother due to intrapartum fever yielded Candida albicans. Cultures of vaginal discharge and neonate skin also yielded C. albicans with the same in vitro susceptibly pattern. No alternative source for candidemia was identified. The clinical course after starting a systemic antifungal therapy was favorable in both the mother and the neonate, with clearance of candidemia and resolution of the skin lesions. CONCLUSIONS: CCC must be considered in full-term newborns with maculopapular rash at birth or during the first days of life. The absence of alternative sources for bloodstream infection in the present case suggests a potential etiopathogenic relationship between CCC and maternal candidemia. It is reasonable to rule out postpartum candidemia when CCC is suspected.

Here, a cotton wound dressing was prepared with control release of Ketoconazole (KZ) to kill skin fungus. KZ alone and KZ/ß-cyclodextrin (ß-CD) were loaded on cotton through diverse methods. The drug release, antimicrobial activities against C. albicans, A. niger, E. coli and S. aureus and also cell cytotoxicity were studied. 1H NMR ensured the formation of KZ/ß-CD complex, SEM images showed surface morphology and confirmed stability. KZ interestingly reacted with the cotton in the batch treatment possibly due to the two active chlorine groups, high temperature and relatively long treatment time. Good antifungal activities and slow release reported for the KZ treated fabric, however KZ/ß-CD loaded more on the fabric with regular and slow release for longer time. The batch performed better than continuous method indicated good antifungal activities with more KZ loading and slower release. Also a cross-linking agent along with ß-CD/KZ prolonged the release time with excellent washing stability.

Cutaneous candidiasis is a common skin disease, and several treatments have been investigated within the last fifty years. Yet, systematic reviews are lacking, and evidence-based topical and systemic treatment strategies remain unclear. Thus, the aim of this review was to summarize efficacy and adverse effects of topical and oral therapies for cutaneous candidiasis in all age groups. Two individual researchers searched PubMed and EMBASE for 'cutaneous candidiasis' and 'cutaneous candidiasis treatment', 'intertrigo', 'diaper dermatitis' and 'cheilitis'. Searches were limited to 'English language', 'clinical trials' and 'human subjects', and prospective clinical trials published in abstracts or articles were included. In total, 149 studies were identified, of which 44 were eligible, comprising 41 studies of 19 topical therapies and four studies of three systemic therapies for cutaneous candidiasis. Topical therapies were investigated in infants, children, adolescents, adults and elderly, while studies of systemic therapies were limited to adolescents and adults. Clotrimazole, nystatin and miconazole were the most studied topical drugs and demonstrated similar efficacy with complete cure rates of 73%-100%. Single-drug therapy was as effective as combinations of antifungal, antibacterial and topical corticosteroid. Four studies investigated systemic therapy, and oral fluconazole demonstrated similar efficacy to oral ketoconazole and topical clotrimazole. Limitations to this review were mainly that heterogeneity of studies hindered meta-analyses. In conclusions, clotrimazole, nystatin and miconazole were the most studied topical drugs and demonstrated equal good efficacy and mild adverse effects similar to combinations of antifungal, antibacterial and topical corticosteroids. Oral fluconazole was as effective as topical clotrimazole and is the only commercially available evidence-based option for systemic treatment of cutaneous candidiasis.

Clotrimazole is widely used for the management of cutaneous candidiasis infection. The low solubility of clotrimazole and excipient-related topical side effects (of currently available marketed products) cause the compromised efficacy of the therapy with poor patient compliance. In the present investigation, a clotrimazole nanocrystal-based nanogel was developed. Clotrimazole nanocrystals were optimized with studying the impact of individual process parameters of the media milling technique. The optimum level of individual process parameters was considered in the development of optimized batches. A promising result was obtained with a non-ionic stabilizer, polysorbate 80, at a concentration of 1.5%w/v, showing a distinct reduction in the particle size from above 31 µm to 264 nm and a polydispersity index of 0.211 with media milling at 1500 rpm for 6 h. This result was found to be in concordance with the TEM images, revealing a sharp diminution in particle morphology. Powder X-ray diffraction and differential scanning calorimetry results revealed crystallinity of clotrimazole (CTZ) in nanocrystal form. The optimized nanocrystal suspension was formulated into nanogel with carbopol 934, having a viscosity of 86.43 ± 2.06 Pa s at 25°C, which enhanced the ease of application of CTZ nanocrystals topically. A diffusion study showed around 82% of CTZ is transported across the membrane with the flux of 110.07 µg cm-2 h-1. In vivo results of the nanogel revealed improvement in CTZ release with 52% CTZ retention in different strata of the skin. The developed nanogel showed a significant improvement in the eradication of fungal infection within 10 days of application over Candida albicans-induced Wistar rat model. In a nutshell, the CTZ nanocrystal-loaded nanogel could achieve the goal of retaining CTZ in skin layers providing a prolonged effect and was able to treat cutaneous candidiasis in a short span with improved compliance for the candidiasis patients.

BACKGROUND: Dual-release mechanism of ethosomal gels (ie, ethosomes and gel) makes them as versatile drug delivery systems for topical applications. Clove oil is obtained from the clove buds exhibited broad antifungal and antibacterial activity. Cutaneous candidiasis is the infection caused by Candida albicans or other Candida species. AIM: The aim of the present study was to prepare ethosomal gel of clove oil and evaluate its effectiveness in the treatment of cutaneous candidiasis. METHODS: Ethosomes of clove oil was formulated by using varying concentrations of soyaphosphotidyl choline and ethanol, and later, it was incorporated into carbapol 974 base gels to form ethosomal gel. The prepared ethosomal gels were also evaluated for spreadability, drug release studies, ex vivo permeation study, and antifungal activity. RESULTS: The optimized formulation did not cause any irritation to the skin since the pH of formulation was in the pH range of skin. The ethosomal gel showed satisfactory antifungal activity against the fungus C. albicans compared to pure clove oil. CONCLUSIONS: The results showed that developed formulation could be promising one in the topical delivery of clove oil for the treatment of cutaneous candidiasis.
