RESUMO

The European Confederation of Medical Mycology (ECMM), formed due to the surge in invasive fungal infections (IFI), initiated the Excellence Centers program in 2016 to guide stakeholders to leading medical mycology sites. This report focuses on the Cologne ECMM Excellence Center, recognized with Diamond status for active global involvement in 2017. The center offers free consultation via email and phone, responding within 24 h for life-threatening IFI, collecting data on origin, pathogens, infection details, and more. Over two years, 189 requests were received globally, predominantly from Germany (85%), mainly involving Aspergillus spp., Mucorales, and Candida spp. Fungal mixed infections occurred in 4% of cases. The center's service effectively addresses IFI challenges, advocating for a comprehensive study encompassing all ECMM Excellence Centers to enhance global mycological care. Proactive expansion of consultancy platforms is crucial, with future analyses needed to assess expert advice's impact on patient outcomes.

RESUMO

BACKGROUND: The International Society for Human and Animal Mycology (ISHAM) working group proposed recommendations for managing allergic bronchopulmonary aspergillosis (ABPA) a decade ago. There is a need to update these recommendations due to advances in diagnostics and therapeutics. METHODS: An international expert group was convened to develop guidelines for managing ABPA (caused by Aspergillus spp.) and allergic bronchopulmonary mycosis (ABPM; caused by fungi other than Aspergillus spp.) in adults and children using a modified Delphi method (two online rounds and one in-person meeting). We defined consensus as ≥70% agreement or disagreement. The terms "recommend" and "suggest" are used when the consensus was ≥70% and <70%, respectively. RESULTS: We recommend screening for A. fumigatus sensitisation using fungus-specific IgE in all newly diagnosed asthmatic adults at tertiary care but only difficult-to-treat asthmatic children. We recommend diagnosing ABPA in those with predisposing conditions or compatible clinico-radiological presentation, with a mandatory demonstration of fungal sensitisation and serum total IgE ≥500 IU·mL-1 and two of the following: fungal-specific IgG, peripheral blood eosinophilia or suggestive imaging. ABPM is considered in those with an ABPA-like presentation but normal A. fumigatus-IgE. Additionally, diagnosing ABPM requires repeated growth of the causative fungus from sputum. We do not routinely recommend treating asymptomatic ABPA patients. We recommend oral prednisolone or itraconazole monotherapy for treating acute ABPA (newly diagnosed or exacerbation), with prednisolone and itraconazole combination only for treating recurrent ABPA exacerbations. We have devised an objective multidimensional criterion to assess treatment response. CONCLUSION: We have framed consensus guidelines for diagnosing, classifying and treating ABPA/M for patient care and research.

RESUMO

The success of the clinical management of invasive fungal diseases (IFD) is highly dependent on suitable tools for timely and accurate diagnosis for effective treatment. An in-depth analysis of the ability of European institutions to promptly and accurately diagnose IFD was previously conducted to identify limitations and aspects to improve. Here, we evaluated and discussed the specific case of Portugal, for which, to our knowledge, there are no reports describing the national mycological diagnostic capacity and access to antifungal treatment. Data from 16 Portuguese medical institutions were collected via an online electronic case report form covering different parameters, including institution profile, self-perceived IFD incidence, target patients, diagnostic methods and reagents, and available antifungals. The majority of participating institutions (69%) reported a low-very low incidence of IFD, with Candida spp. indicated as the most relevant fungal pathogen, followed by Aspergillus spp. and Cryptococcus spp. All institutions had access to culture and microscopy, whereas 94 and 88% were able to run antigen-detection assays and molecular tests, respectively. All of the institutions capable of providing antifungal therapy declared to have access to at least one antifungal. However, echinocandins were only available at 85% of the sites. Therapeutic drug monitoring (TDM) was reported to remain a very restricted practice in Portugal, being available in 19% of the institutions, with the TDM of itraconazole and posaconazole performed in only 6% of them. Importantly, several of these resources are outsourced to external entities. Except for TDM, Portugal appears to be well-prepared concerning the overall capacity to diagnose and treat IFD. Future efforts should focus on promoting the widespread availability of TDM and improved access to multiple classes of antifungals, to further improve patient outcomes.

RESUMO

We present the case of a twenty six year-old woman with rheumatoid arthritis, treated with certolizumab. She sought medical attention due to cough, fever and night sweats. X-ray exam showed a miliary pneumonia. She was treated for tuberculosis and 50days later she presented with aphasia. Magnetic nuclear resonance revealed brain lesions. Histoplasma capsulatum PCR test and urinary antigen were positive, so an antifungal treatment with voriconazole was started. Visual adverse effects forced to change the antifungal schedule in both the length of treatment and the antifungal drug. With this measure the patient progressed favorably. The test of urinary Histoplasma capsulatum antigen and PCR amplification were key to make a diagnosis and also for a follow-up.

RESUMO

Natural and human-made disasters have long played a role in shaping the environment and microbial communities, also affecting non-microbial life on Earth. Disaster microbiology is a new concept based on the notion that a disaster changes the environment causing adaptation or alteration of microbial populations -growth, death, transportation to a new area, development traits, or resistance- that can have downstream effects on the affected ecosystem. Such downstream effects include blooms of microbial populations and the ability to colonize a new niche or host, cause disease, or survive in former extreme conditions. Throughout history, fungal populations have been affected by disasters. There are prehistoric archeological records of fungal blooms after asteroid impacts and fungi implicated in the fall of the dinosaurs. In recent times, drought and dust storms have caused disturbance of soil fungi, and hurricanes have induced the growth of molds on wet surfaces, resulting in an increased incidence of fungal disease. Probably, the anticipated increase in extreme heat would force fungi adaptation to survive at high temperatures, like those in the human body, and thus be able to infect mammals. This may lead to a drastic rise of new fungal diseases in humans.


Los desastres naturales o los causados por el hombre impactan la formación de ecosistemas y comunidades microbianas, y también afectan las formas de vida no microbianas. Este concepto es conocido como "microbiología de desastres", una subespecialización de la microbiología, basada en los cambios ambientales generados por un desastre y las posibles adaptaciones o alteraciones de las poblaciones microbianas ­crecimiento, muerte, trasporte a una nueva región, o adquisición de resistencia o de nuevas características­ que influirán en el moldeamiento del ecosistema transformado. Algunos de los efectos de estas adaptaciones pueden ser: el surgimiento de poblaciones microbianas, la habilidad de colonizar nuevos nichos u huéspedes, la generación de nuevas enfermedades, o el crecimiento de microorganismos en condiciones que antes eran "extremas" para ellos. A lo largo de la historia, varias poblaciones de hongos han sido afectadas por desastres. Existen registros arqueológicos prehistóricos que evidencian la presencia y el crecimiento de hongos luego del impacto de asteroides, y otros de hongos relacionados con la extinción de los dinosaurios. Actualmente, las sequías y las tormentas de polvo causan perturbaciones en las comunidades de hongos del suelo, y los huracanes inducen el crecimiento de hongos filamentosos en superficies húmedas, lo que aumenta la cantidad de enfermedades por hongos. Además, con el aumento de las temperaturas extremas es posible que los hongos puedan adaptarse para sobrevivir a temperaturas más altas, equivalentes a las temperaturas corporales, y nuevas especies puedan infectar mamíferos. Esto puede llevar a un aumento drástico de las infecciones fúngicas en humanos.

RESUMO

In forensic case work, fungal growth is occasionally observed on decomposed cadavers, however, the isolation of these organisms is not always carried out routinely. The usefulness of investigating fungi isolated from corpses in forensic settings, has been reported, such as providing trace evidence, estimating the time since death, and ascertaining the time of deposition. A 32-year-old male missing for 4 months, was found in a car in a forest far from his home and had died from blood loss, having been stabbed with a kitchen knife in the left side of his chest. Whitish or white greenish colonies ranging 5 cm to 8 cm in size were observed over his whole body. Penicillium commune and Cladosporium cladosporioides were isolated from the colonies. A 49-year-old male missing for one month, and was found dead at 500 m elevation in the mountains. An autopsy was conducted, but the cause of death could not be determined. Dark greenish or whitish colonies were found on his face and neck, and Epicoccum nigrum, Mucor sp.. Cladosporium sp., and Pestalotiopsis sp. were isolated. Penicillium sp. and Cladosporium sp. are major indoor fungi, and Epicoccum sp. and Pestalotiopsis sp. are plant pathogens found in outdoor environments. There was no discrepancy between the police statement and findings of the corpse such as place discovered, types of isolated fungi, and estimated time since death. Identifying fungi on cadavers may aid in forensic casework, and further studies are needed to develop for the use of fungi as a forensic tool.

RESUMO

Introducción. La tiña de la cabeza es una micosis que se presenta en el tejido queratinizado, afecta al cuero cabelludo y puede causar alopecia, prurito y descamación. Este tipo de micosis es más frecuente en niños de edad escolar, por lo que puede desencadenar un problema de salud pública. En Colombia, los principales agentes etiológicos reportados son los dermatofitos zoofílicos. Objetivo. En el presente estudio se buscó caracterizar un brote de tinea capitis en 32 niños de un colegio de la zona rural del departamento del Cauca. Materiales y métodos. Se llevó a cabo una investigación epidemiológica de campo en la que se aplicó una encuesta estructurada para caracterizar aspectos sociodemográficos y factores predisponentes para su ocurrencia. Se recolectaron muestras de escamas de cuero cabelludo y cabellos afectados para estudios micológicos. Finalmente, por medio de la Secretaría Departamental del Cauca y del hospital local, se manejó el brote de tinea capitis y se hicieron recomendaciones a los niños, los padres de familia y la población en general para prevenir estas micosis. Este estudio contó con el consentimiento informado verbal por parte de los padres de familia y los niños. Resultados. El agente etiológico aislado en el 63 % de las muestras recolectadas fue Trichophyton tonsurans y el principal factor predisponente para esta micosis fue compartir máquinas rasuradoras (87,5 %). El agente etiológico de este brote de tinea capitis no inflamatoria fue un dermatofito antropofílico. Conclusión. Idealmente, se deben practicar los estudios micológicos con el fin de establecer el agente etiológico y, así, plantear las terapéuticas y recomendaciones según las guías de manejo. Además, se debe realizar un trabajo multidisciplinario para el control del brote y la educación de la población respecto a esta micosis.


Introduction. Tinea capitis is a mycosis of keratinized tissue, which affects the scalp and may cause alopecia, pruritus, and desquamation. This type of mycosis is more frequent in school-age children, and it may represent a public health problem; the main etiological agents reported for Colombia are zoophilic dermatophytes. Objective. To characterize an outbreak of Tinea capitis in 32 children from a rural school in the department of Cauca. Materials and methods. We conducted an epidemiological field study using a structured survey to characterize sociodemographic aspects and predisposing factors for this mycosis. We collected samples of affected scalp scales and hair for mycological studies. The children and the general population received recommendations, about these mycoses' prevention, from Cauca's health authorities and the local hospital. The parents verbally approved the informed consent. Results. The etiological agent isolated in 63% of the collected samples was Trichophyton tonsurans, an anthropophilic dermatophyte, and the main predisposing factor was sharing razors (87.5%). Conclusions. Ideally, mycological studies define the etiological agent to propose therapeutics and recommendations in agreement with management guidelines. Implementation of multidisciplinary measures to control the outbreak and educate the population is required.

RESUMO

The ability of fungi to mineralize substrates is a common but underestimated phenomenon. Now, researchers have demonstrated the usefulness of this process in fossilization by documenting the formation of hydroxyapatite nanofibres. This opens new avenues in palaeomycology and palaeontology.

RESUMO

Italian mycologist Pier Andrea Saccardo is best remembered for his monumental Sylloge Fungorum, the first 'modern' effort to compile all identified fungi within a single classification scheme. The existing history of mycology is limited and has primarily focused on developments within England, but this article argues that Saccardo and his collaborators on the Sylloge supported a vital transnational expansion of mycological knowledge exchange and played a crucial role in stabilizing the tangled knot of local naming and identification among the world's amateur and professional mycologists. Written in the 'universal' scientific language of Latin, the Sylloge served as an early database of fungal knowledge and symbolized a broader unification of mycological inquiry in a moment of expanded scientific correspondence. The article situates this proto-database in broader histories of big data in biology and shows how the Sylloge formed a globalizing foundation for the twentieth century's major collecting and taxonomic advances in mycology.

RESUMO

Criminal cases are studied from several disciplines to link a suspect with a criminal act. In this case, a man was reported missing in a coastal area in Buenos Aires Province, Argentina. The victim's relatives pointed to a possible suspect, and the local police carried out the investigation. We contributed to this research by applying palynological and mycological techniques. Palynomorphs and fungal spores offer valuable trace evidence, as they can be easily transferred between objects and crime scenes due to their minute size and persist on them for a long time. The victim was found 25 days later, lying on sandy soil, which partially covered the body, 35 km from where the suspect was arrested. Comparative samples were collected from the crime scene and the suspect's home and belongings (clothes, footwear, and seized vehicle). The palynological associations obtained from the crime scene and the defendant's belongings were dominated by diatoms and acritarchs (Acantomorphitae), all elements of marine origin, and a high CFU number of Bipolaris cynodontis, which allowed the defendant's clothing to be related to the place of corpse discovery. Soil from the defendant's home had an entirely continental composition, and the fungal biota was characteristic of prairie areas which were different from those of the crime scene.

RESUMO

Online social media networks are an integral part of modern life. Microblogging sites such as Twitter have hundreds of millions of active users globally and have been enthusiastically adopted by many in the medical profession. For advancing a relatively neglected field such as fungal infection, this can be especially advantageous. Education, research networking, case discussions and public and patient engagement can all be greatly enhanced through the use of social media networks. This review highlights the ways in which this can work successfully in the case of aspergillosis and fungal infection in general, as well as highlighting the dangers and pitfalls of social media medicine.

RESUMO

BACKGROUND: The aim of this study was to culture fungi from the nasal discharge of patients with chronic rhinosinusitis (CRS) using both a traditional and Ponikau et al's method, and subsequently compare the culture results between CRS with nasal polyps (CRSwNPs) and without nasal polyps (CRSsNPs), and between eosinophilic and noneosinophilic CRS. METHODS: Eighty-one CRS patients with CRS who underwent functional endoscopic sinus surgery were enrolled. Before surgery, the severity of each patient's CRS was evaluated through an endoscopic examination and CT scan. Swab samples were collected from the middle meatus for traditional fungal cultures using cotton-tipped sticks. Afterward, the ipsilateral nasal cavity was irrigated, with the irrigated fluid processed using Ponikau et al's method for fungal culture. RESULTS: The endoscopic and CT scores were significantly higher in CRSwNPs than CRSsNPs, but were not different between eosinophilic CRS and noneosinophilic CRS. Using Ponikau et al's method, 61/81 (75.3%) of the specimens grew fungi. Among them, 20 of 32 (62.5%) CRSwNPs specimens and 41 of 49 (83.7%) CRSsNPs specimens grew fungi. For eosinophilic CRS specimens, 35 of 46 (76.1%) grew fungi, and 26 of 35 (74.3%) noneosinophilic CRS specimens grew fungi. The fungal culture rate was borderline significantly higher in CRSsNPs than CRSwNPs ( p = 0.058) but was not significantly different between eosinophilic CRS and noneosinophilic CRS ( p = 1). However, Cladosporium was significantly more common in CRSsNPs than CRSwNPs ( p = 0.048). CONCLUSION: Our results showed that the mycology of CRS was different between CRSwNPs and CRSsNPs.

RESUMO

INTRODUCTION: Invasive fungal infections (IFIs) in Asia/Pacific are a particular threat to patients with malignancies, uncontrolled diabetes mellitus or undiagnosed/untreated human immunodeficiency virus infection and acquired immunodeficiency syndrome (HIV/AIDS). Adequate and early access to diagnostic tools and antifungals is essential for IFI clinical management and patient survival. METHODS: Details on institution profile, self-perception on IFI, and access to microscopy, culture, serology, antigen detection, molecular testing, and therapeutic drug monitoring for IFI were collected in a survey. RESULTS: As of June 2022, 235 centres from 40 countries/territories in Asia/Pacific answered the questionnaire. More than half the centres were from six countries: India (25%), China (17%), Thailand (5%), Indonesia, Iran, and Japan (4% each). Candida spp. (93%) and Aspergillus spp. (75%) were considered the most relevant pathogens. Most institutions had access to microscopy (98%) or culture-based approaches (97%). Furthermore, 79% of centres had access to antigen detection, 66% to molecular assays, and 63% to antibody tests. Access to antifungals varied between countries/territories. At least one triazole was available in 93% of the reporting sites (voriconazole [89%] was the most common mould-active azole), whereas 80% had at least one amphotericin B formulation, and 72% had at least one echinocandin. CONCLUSION: According to the replies provided, the resources available for IFI diagnosis and management vary among Asia/Pacific countries/territories. Economical or geographical factors may play a key role in the incidence and clinical handling of this disease burden. Regional cooperation may be a good strategy to overcome shortcomings.

RESUMO

Brazilian medical mycology considerably expanded in the last decades due to the efforts of several pioneers who started and expanded mycology during the twentieth century. In this manuscript, we highlight some of the contributions of one of these pioneers: Professor Luiz R. Travassos, who started his career in the field of microbiology in the 1960s. We will discuss his contributions to the areas of medical mycology and glycobiology, with a focus on glycosphingolipids, sialic acids, and surface enzymes.
