Cladosporium species novum Invasive Pulmonary Infection in a Patient with Post-COVID-19 Syndrome and AIDS. Diagnostics (Basel) 2025; 15:781. [PMID: 40150123 PMCID: PMC11941363 DOI: 10.3390/diagnostics15060781] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2025] [Revised: 03/17/2025] [Accepted: 03/17/2025] [Indexed: 03/29/2025] Open
Abstract
Background and Clinical Significance: Since the prevalence of fungal lung infections is increasing, certain agents, such as Cladosporium spp., have emerged as unexpected causes. Cladosporium spp. fungi are ubiquitous in environments such as soil, fruits, and wine corks; they are a part of the normal human skin flora; and they are known respiratory allergens. Case Presentation: A patient with a history of post-COVID-19 syndrome and AIDS presented with lung pathology indicative of an invasive fungal infection. The initial histopathological examination revealed numerous yeast-like cells with narrow-based budding, which led to a mistaken diagnosis of cryptococcosis. However, further detailed examination revealed sparse hyphae in the lung tissue, suggesting a more complex fungal infection. Molecular analyses and sequence BLAST alignment were performed, ultimately identifying the infectious agent as "Cladosporium species novum", a rare cause of invasive pulmonary cladosporiasis. Conclusions: Invasive pulmonary cladosporiasis is a rare condition, and the morphological features of the fungus alone were insufficient to establish a correct diagnosis. A comprehensive pathohistological and molecular approach with bioinformatics tools is essential for the correct identification of rare and potentially life-threatening fungal pathogens in immunocompromised patients.

Abstract
STUDY OBJECTIVE Complex pharmacotherapy in cancer patients increases the likelihood of drug-drug interactions (DDIs). Pharmacists play a critical role in the identification and management of DDIs. The aim of present study was to evaluate the role of pharmacist in identifying antifungal drug interactions in cancer patients and providing relevant recommendations. METHODOLOGY A retrospective, cross-sectional study was conducted to identify antifungal drug interactions over the period of 5 years (2019-2023) among cancer patients. Electronic medical record of 384 hospitalized patients receiving systemic antifungal therapy were reviewed. Severity of interactions and risk classification were made using UptoDate® LexidrugTM software. Pharmacists' recommendations regarding DDIs were also documented. Descriptive statistics and logistic regression were applied to interpret results. RESULTS Antifungals were more frequently prescribed to adult patients (53.9%). Female cancer patients were significantly more likely to encounter DDIs than males (p < 0.003). Type of cancer and fungal infections were significantly associated with incidence of DDIs (p < 0.01; p = 0.000). Pharmacist identified DDIs in 53.9% antifungal prescriptions with 22.2% classified as major interactions. A substantial proportion of these interactions involved voriconazole (40.1%). Majority of pharmacist's recommendations included dose optimization of voriconazole (10.4%), close monitoring of RFTs (8.9%) and withholding amphotericin (5.2%) during chemotherapy. All of the recommendations made by pharmacists were accepted by physicians (100%). CONCLUSION The findings indicate that pharmacists identified DDIs in 53.9% of prescriptions and all of their recommendations were accepted by physicians. This highlights the critical role of pharmacists in detecting potential interactions, ensuring medication safety, and minimizing adverse effects associated with complex pharmacotherapy.

Abstract
Background Mycetoma is a chronic granulomatous disease affecting the skin, subcutaneous tissues, and bones, particularly in tropical and subtropical regions. Sudan, especially its Eastern Sinnar locality, experiences a significant burden due to environmental conditions and limited access to healthcare, while the population's lack of awareness and understanding often leads to delays in diagnosis and treatment. Methods We conducted a descriptive cross-sectional, community-based study in Eastern Sinnar, Sudan, to investigate the prevalence, risk factors, and awareness of mycetoma among local residents. Using Cochran's formula, we calculated a required sample size of 400 participants from a total population of 245 201. Then, we randomly selected these participants from five villages chosen through stratified sampling. Data were collected via a validated questionnaire assessing sociodemographic characteristics and mycetoma-related information, a review of medical records to confirm infection types and prevalence, and interviews with the Directorate of the Mycetoma Centre in Sinnar. We used χ2 tests for associations in our analysis, with P-values ≤0.05 indicating statistical significance. Results The mycetoma prevalence was 5.4%, with males comprising 76.4% of infected cases. However, the difference in infection rates between genders was not statistically significant (P = 0.248). While infection rates were higher among certain occupational groups, such as farmers and shepherds, the association between occupation and mycetoma infection was non-significant (P = 0.107). We also found no significant associations with educational level (P = 0.104) or age (P = 0.514), but did detect significant associations for family history of infection (P < 0.001), animal ownership (P = 0.004), and not wearing shoes during work (P = 0.05). Awareness of mycetoma was relatively high, with 78.3% of respondents acknowledging the disease, though knowledge gaps remained, especially regarding its transmission, with only 36.1% believing it to be transmissible. Conclusions The study highlights the need for targeted health education programmes, particularly emphasising protective footwear and safe animal-handling practices. These findings are crucial for informing public health strategies aimed at reducing the burden of mycetoma in endemic regions such as Eastern Sinnar.

Abstract
Cordyceps militaris is a medicinal mushroom widely utilized in traditional East Asian medicine, recognized for its diverse therapeutic properties. This review explores the potential of C. militaris-derived bioactive gels for applications in dermatology and skincare, with a particular focus on their therapeutic and anti-aging benefits. In response to the rising incidence of skin cancers and the growing demand for natural bioactive ingredients, C. militaris has emerged as a valuable source of functional compounds, including cordycepin, polysaccharides, and adenosine. These compounds exhibit multiple bioactivities, including apoptosis induction, cell cycle arrest, and anti-inflammatory effects, which have been shown to be particularly effective against melanoma and other skin cancers. Additionally, the antioxidant properties of C. militaris enhance skin resilience by scavenging reactive oxygen species, reducing oxidative stress, and promoting collagen synthesis, thereby addressing skin health and anti-aging requirements. The potential for incorporating C. militaris compounds into gel-based formulations for skincare is also examined, either as standalone bioactives or in combination with synergistic ingredients. Emphasis is placed on the necessity of clinical trials and standardization to establish the safety, efficacy, and reproducibility of such applications. By providing a safer alternative to synthetic agents, C. militaris-derived bioactive gels represent a promising advancement in dermatology and skincare.

The nasal mycobiome of individuals with allergic rhinitis and asthma differs from that of healthy controls in composition, structure and function. Front Microbiol 2024; 15:1464257. [PMID: 39741585 PMCID: PMC11685215 DOI: 10.3389/fmicb.2024.1464257] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2024] [Accepted: 10/17/2024] [Indexed: 01/03/2025] Open
Abstract
Allergic rhinitis (AR) and asthma (AS) are two of the most common chronic respiratory diseases and a major public health concern. Multiple studies have demonstrated the role of the nasal bacteriome in AR and AS, but little is known about the airway mycobiome and its potential association to airway inflammatory diseases. Here we used the internal transcriber spacers (ITS) 1 and 2 and high-throughput sequencing to characterize the nasal mycobiome of 339 individuals with AR, AR with asthma (ARAS), AS and healthy controls (CT). Seven to ten of the 14 most abundant fungal genera (Malassezia, Alternaria, Cladosporium, Penicillium, Wallemia, Rhodotorula, Sporobolomyces, Naganishia, Vishniacozyma, and Filobasidium) in the nasal cavity differed significantly (p ≤ 0.049) between AS, AR or ARAS, and CT. However, none of the same genera varied significantly between the three respiratory disease groups. The nasal mycobiomes of AR and ARAS patients showed the highest intra-group diversity, while CT showed the lowest. Alpha-diversity indices of microbial richness and evenness only varied significantly (p ≤ 0.024) between AR or ARAS and CT, while all disease groups showed significant differences (p ≤ 0.0004) in microbial structure (i.e., beta-diversity indices) when compared to CT samples. Thirty metabolic pathways (PICRUSt2) were differentially abundant (Wald's test) between AR or ARAS and CT patients, but only three of them associated with 5-aminoimidazole ribonucleotide (AIR) biosynthesis were over abundant (log2 Fold Change >0.75) in the ARAS group. AIR has been associated to fungal pathogenesis in plants. Spiec-Easi fungal networks varied among groups, but AR and ARAS showed more similar interactions among their members than with those in the CT mycobiome; this suggests chronic respiratory allergic diseases may disrupt fungal connectivity in the nasal cavity. This study contributes valuable fungal data and results to understand the relationships between the nasal mycobiome and allergy-related conditions. It demonstrates for the first time that the nasal mycobiota varies during health and allergic rhinitis (with and without comorbid asthma) and reveals specific taxa, metabolic pathways and fungal interactions that may relate to chronic airway disease.

Abstract
Skin problems are common, affecting up to one-third of the population during their lifetime, and they are frequently encountered by advanced clinical practitioners (ACPs) in both primary and secondary care settings. Despite the prevalence of dermatological presentations, ACPs often feel unprepared to conduct a thorough dermatological history and examination. This article aims to provide guidance to trainees and qualified ACPs, whether in acute hospital settings or primary care, to perform dermatological assessments and examinations systematically. This is the first article in a two-part series on dermatological assessment.

Abstract
With increasing use of broad-spectrum antibiotics, advances in organ and stem-cell transplant therapy, and the continued diabetes mellitus II epidemic, as well as other risk factors, reports of fungal infections of the CNS have been increasing. The most lethal subset is the angioinvasive fungal infection. Aspergillus fumigatus, Mucor, and Fusarium tend to affect immunocompromised individuals depending on their risk factors. Exserohilum rostratum and Cladophialaphora species tend to infect immunocompetent individuals. Early diagnosis and treatment are imperative for improved outcomes and reduced morbidity and mortality. Clinical presentation is often nonspecific, while neuroimaging can be helpful for accurate diagnosis. CT of the head and/or the maxillofacial structures is the primary imaging modality. Once the infection begins to proliferate, areas of vasogenic and cytotoxic edema, with regional mass effect and shift of the midline structures may be seen. These findings, however, are often nonspecific and may also be seen in underlying neoplasm, inflammatory processes, and other intracranial infections. Characteristic findings on T1, T2, diffusion-weighted imaging (DWI), and gradient echo sequences (GRE) may help to further narrow the differential diagnoses. We present a review of neuroimaging findings that will aid the neuroradiologist in distinguishing intracranial angioinvasive fungal infections and lead to improved patient outcomes.

Abstract
Allergic rhinitis and asthma are two prevailing chronic airway diseases and serious public health concerns. Previous research has already described the role of the airway bacteriome in these two diseases, but almost no study so far has explored the mycobiome and its possible association to airway inflammation. Here we sequenced the internal transcribed spacers (ITS) 1 and 2 to characterize the oral mycobiome of 349 Portuguese children and young adults with allergic rhinitis alone (AR) or with asthma (ARAS), asthmatics (AS) and healthy controls (HC). Our genomic analyses showed that the two most abundant fungal phyla (Ascomycota and Basidiomycota) and 3-5 of the 14 most abundant fungal genera (Cladosporium, Aspergillus, Aleurina, Candida and Rhodotorula) in the mouth differed significantly (P ≤ 0.04) between both rhinitic groups and HC. However, none of the same taxa varied significantly between the three respiratory disease groups (AR, ARAS and AS). The oral mycobiomes of respiratory ill patients showed the highest intra-group diversity (microbial richness and evenness), while HC showed the lowest, with all alpha-diversity indices varying significantly (P ≤ 0.0424) between them. Similarly, all disease groups showed significant differences (P ≤ 0.0052) in microbial structure (i.e., beta-diversity indices) when compared to HC samples. Thirty metabolic pathways (PICRUSt2) were differentially abundant (Wald's test) between AR or ARAS and HC patients, but only one of them (D-galactose degradation I) was over abundant (log2 Fold Change >0.75) in the ARAS group. Spiec-Easi fungal networks varied greatly among groups, which suggests chronic respiratory allergic diseases may alter fungal connectivity in the mouth. This study increases our comprehension of the role of the oral mycobiome in allergy-related conditions. It shows for the first time that the oral mycobiota changes during health and allergic rhinitis (with and without asthma comorbidity) and highlights specific taxa, metabolic pathways and fungal interactions that may relate to chronic airway disease.

Cureus 2024; 16:e68375. [PMID: 39355457 PMCID: PMC11443987 DOI: 10.7759/cureus.68375] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2024] [Accepted: 09/01/2024] [Indexed: 10/03/2024] Open
Abstract
Coccidioidomycosis and histoplasmosis are endemic mycoses caused by the Coccidioides species and Histoplasma capsulatum, respectively. While these fungal infections are often associated with immunocompromised individuals, they pose significant risks to immunocompetent hosts. This review comprehensively analyzes these infections in immunocompetent individuals, focusing on clinical features, diagnostic approaches, and management strategies. The current understanding of coccidioidomycosis and histoplasmosis in immunocompetent individuals includes their clinical presentations, diagnostic methodologies, and treatment options. A literature review encompassed recent studies, clinical guidelines, and expert opinions. Data were analyzed to highlight critical aspects of the clinical manifestations, diagnostic processes, and management of these infections in immunocompetent patients. Coccidioidomycosis typically presents with pulmonary symptoms that may range from mild to severe and can include chronic and disseminated forms. Histoplasmosis also presents a spectrum of pulmonary symptoms with the potential for extrapulmonary dissemination. Diagnostic approaches for both infections involve clinical evaluation, serological tests, culture, and imaging studies. Management strategies include antifungal therapies such as fluconazole and itraconazole for coccidioidomycosis and itraconazole and amphotericin B for histoplasmosis, with treatment duration and monitoring tailored to the severity of the infection. Coccidioidomycosis and histoplasmosis can significantly affect immunocompetent individuals, with clinical presentations varying widely from mild to severe. Accurate diagnosis and appropriate management are crucial for optimal outcomes. This review underscores the importance of awareness and timely intervention in managing these endemic mycoses and highlights the need for continued research into better diagnostic and therapeutic approaches.

Abstract
NKT cells, unique lymphocytes bridging innate and adaptive immunity, offer significant potential for managing inflammatory disorders like asthma. Activating iNKT induces increasing IFN-γ, TGF-β, IL-2, and IL-10 potentially suppressing allergic asthma. However, their immunomodulatory effects, including granzyme-perforin-mediated cytotoxicity, and expression of TIM-3 and TRAIL warrant careful consideration and targeted approaches. Although CAR-T cell therapy has achieved remarkable success in treating certain cancers, its limitations necessitate exploring alternative approaches. In this context, CAR-NKT cells emerge as a promising approach for overcoming these challenges, potentially achieving safer and more effective immunotherapies. Strategies involve targeting distinct IgE-receptors and their interactions with CAR-NKT cells, potentially disrupting allergen-mast cell/basophil interactions and preventing inflammatory cytokine release. Additionally, targeting immune checkpoints like PDL-2, inducible ICOS, FASL, CTLA-4, and CD137 or dectin-1 for fungal asthma could further modulate immune responses. Furthermore, artificial intelligence and machine learning hold immense promise for revolutionizing NKT cell-based asthma therapy. AI can optimize CAR-NKT cell functionalities, design personalized treatment strategies, and unlock a future of precise and effective care. This review discusses various approaches to enhancing CAR-NKT cell efficacy and longevity, along with the challenges and opportunities they present in the treatment of allergic asthma.

Abstract
Allergic fungal rhinosinusitis (AFRS) is a subtype of chronic rhinosinusitis, characterized by excessive immune responses to environmental molds or fungi. The diagnosis and classification of AFRS into systemic and local types remain clinically challenging due to overlapping characteristics. This study investigated the prevalence of AFRS, its manifestation and associated factors in systemic and local AFRS. A total of 200 patients diagnosed with fungal rhinosinusitis underwent both skin provocation tests (SPT) and nasal provocation tests (NPT) to confirm AFRS and classify systemic and local types. Patients were considered to have AFRS if either the SPT or NPT was positive. Among these, patients with systemic AFRS were those who had a SPT positive. Local AFRS was when patients had a negative SPT and a positive NPT. Medical history, serum total IgE level, nasal endoscopy examinations, and CT scans were also recorded. Most patients were female (65.8%), with a mean age of 55.6 years (SD = 14.4). Based on the SPT and NPT results, 31% of patients (n = 62) were diagnosed with AFRS. Among these, 54.8% (n = 34) had systemic AFRS, while 45.2% (n = 28) had local AFRS. Patients with AFRS exhibited significantly higher levels of total IgE, eosinophils, and more pronounced signs and symptoms compared to those without AFRS. However, no statistically significant differences were observed between patients with systemic AFRS and those with local AFRS. AFRS was prevalent in our study. Among patients with AFRS, both systemic AFRS and local AFRS were also prevalent. While allergic indicators and clinical presentations can aid in AFRS diagnosis, minimal distinctions were observed between systemic and local AFRS. A comprehensive assessment incorporating both local and systemic allergic responses through provocation tests, such as a combination of skin and nasal tests, is imperative for optimizing AFRS diagnosis and management.

Bayesian analysis suggests independent development of sensitization to different fungal allergens. World Allergy Organ J 2024; 17:100908. [PMID: 38800499 PMCID: PMC11126528 DOI: 10.1016/j.waojou.2024.100908] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2023] [Revised: 03/05/2024] [Accepted: 04/18/2024] [Indexed: 05/29/2024] Open
Abstract
Background Fungi are known for their ability to cause allergies, but data on individual sensitization to them are insufficient. The purpose of the study was to carry out a comprehensive analysis of the fungal allergens' sensitization profile in the Ukrainian population and to determine both population and individual sensitivity to these allergens. Methods We utilized a set of ALEX allergy test data from 20,033 inhabitants of 17 regions of Ukraine from 1 to 89 years conducted in 2020-2022. A complex of programs in the Python language was developed and Bayesian network analysis was applied to determine the sensitivity combinations in individual patients to various fungal components. Results Sensitivity to Alt a 1 dominated and was observed in 79.39% of patients, and 62.17% of them were sensitive solely to Alt a 1. Exclusive sensitivity to Mala s 6 was second in individual patient profiles with a frequency of 4.06%. Combined sensitivity to Alt a 1 - Asp f 3 was third with a share of 3.28%. Pen ch and Cla h extracts stimulated the production of the lowest median sIgE levels. The highest median sIgE levels were for Alt a 1, Mala s 11 and Asp f 6, respectively. Median sIgE levels increased in adults compared to children for all components of Aspergillus fumigatus, as well as for Mala s 5 and Mala s 11. In the rest of the cases, they decreased in adults compared to children. The sensitization rates to fungi in general and specifically to Alternaria were lower in the western parts of Ukraine, especially in the Carpathian region, situated within the Broad-leaved Forest zone. The results of Bayesian modeling revealed that in the case of Alt a 1, the simultaneous absence of sensitivity to Cla h 8, Mala s 11, Mala s 5 and Mala s 6 molecules could condition the presence of sensitization to the major Alternaria allergen with a probability of 92.42%. In all other cases, there was a high probability of absence of sensitivity to particular allergen against the background of absence of sensitivity to other ones, which may indicate the independent development of sensitization to different fungal allergens. Conclusions Sensitivity to Alt a 1 dominated in the studied population with a lower rate in the western regions. The highest median sIgE levels were induced by Alt a 1, Mala s 11 and Asp f 6. Bayesian Analysis suggest a high probability of the independent development of sensitization to different fungal allergens. The idea that sensitization to one allergen may be protective against sensitization to another one(s) requires further clinical study.

Abstract
Airborne fungal spores are a major cause of fungal diseases in humans, animals, and plants as well as contamination of foods. Previous studies found a variety of regulators including VosA, VelB, WetA, and SscA for sporogenesis and the long-term viability in Aspergillus nidulans. To gain a mechanistic understanding of the complex regulatory mechanisms in asexual spores, here, we focused on the relationship between VosA and SscA using comparative transcriptomic analysis and phenotypic studies. The ΔsscA ΔvosA double-mutant conidia have lower spore viability and stress tolerance compared to the ΔsscA or ΔvosA single mutant conidia. Deletion of sscA or vosA affects chitin levels and mRNA levels of chitin biosynthetic genes in conidia. In addition, SscA and VosA are required for the dormant state of conidia and conidial germination by modulating the mRNA levels of the cytoskeleton and development-associated genes. Overall, these results suggest that SscA and VosA play interdependent roles in governing spore maturation, dormancy, and germination in A. nidulans.

Abstract
Among the various prominent fungal infections, superficial ones are widespread. A large number of antifungal agents and their formulations for topical use are commercially available. They have some pharmacokinetic limitations which cannot be retracted by conventional delivery systems. While nanoformulations composed of lipidic and polymeric nanoparticles have the potential to overcome the limitations of conventional systems. The broad spectrum category of antifungals i.e. azoles (ketoconazole, voriconazole, econazole, miconazole, etc.) nanoparticles have been designed, prepared and their pharmacokinetic and pharmacodynamic profile was established. This review briefly elaborates on the types of nano-based topical drug delivery systems and portrays their advantages for researchers in the related field to benefit the available antifungal therapeutics.

Abstract
The purpose of the current study was to prepare and evaluate a citronella oil-loaded microemulsion-based micro-emulgel for the treatment of Candida albicans. The primary objective was to use the skin to transfer hydrophobic medications into the bloodstream. The formulation included cinnamon oil as an antifungal oil and citronella oil as an active pharmaceutical ingredient, respectively. Tween 80 and PEG 200 were used as the surfactant and co-surfactant, respectively, to create phase diagrams. Carbopol 940, one of the frequently used polymers, was investigated for its ability to prepare gel formulations. The optimized (F3) batch contained the highest percentage (87.05 ± 0.03%) of drug content and, according to the statistics provided, had the highest drug release rate of around 87.05% within 4 h. The Korsmeyer-Peppas model with n value of 0.82, which is in the range 0.5-1, had the highest r2 value, indicating that release following non-Fickian/anomalous diffusion provided a better dimension for all of the formulations. The optimized (F3) formulation had stronger antifungal activity in comparison to other formulations. This leads to the conclusion that citronella oil can be made into a micro-emulgel, which may improve its release in aqueous systems while maintaining a high level of drug release at the target site.

Abstract
The relationship between cancer and microorganisms has been extensively studied, with bacteria receiving more attention than fungi. However, fungi have been shown to play a significant role in cancer development and progression. Understanding the underlying mechanisms is crucial for identifying new avenues in prevention and treatment. To evaluate the current state of research on fungi and cancer, we conducted a comprehensive bibliometric analysis. Using the Web of Science Core Collection database, we searched for English-language articles published between 1998 and 2022. Analyzing the resulting publication data, we identified trends, patterns, and research gaps. Our analysis encompassed co-authorship networks, citation analysis, and keyword co-occurrence analysis. With 8283 publications identified, averaging 331.32 publications per year, our findings highlight China, the United States, India, Japan, and Germany as the top contributing countries. The Chinese Academy of Sciences, Sun Yat-Sen University, and University of São Paulo emerged as the most productive institutions. Key themes in the literature included "cancer," "cytotoxicity," "apoptosis," "metabolites," and "fungus." Recent trends indicate increased interest in keywords such as "green synthesis," "molecular docking," "anticancer activity," "antibacterial," "anticancer," and "silver nanoparticles." Our study provides a comprehensive assessment of the current research landscape in the field of fungi and cancer, offering insights into collaborative networks, research directions, and emerging hotspots. The growing publication rate demonstrates the rising interest in the topic, while identifying leading countries, institutions, and research themes serves as a valuable resource for researchers, policymakers, and funders interested in supporting investigations on fungi-derived compounds as potential anti-cancer agents.
