RESUMEN
The epidemiological dynamics of paracoccidioidomycosis (PCM) has been changing over the years. We analyzed secondary public data from the Hospital Information System of the Brazilian Unified Health System (SIH/SUS), focusing on PCM-related hospitalizations and in-hospital deaths. In the period between 2010 and 2019, 396 hospitalizations and 30 deaths were related to PCM among 7 073 334 hospitalizations registered in Rio de Janeiro. We highlight the rising rates, reflecting the increase in the number of acute forms previously reported. Urgent public health policies are essential to prevent poor outcomes related to this neglected mycosis.
Epidemiology of paracoccidioidomycosis has been changing in endemic areas. We analyzed secondary data on hospitalizations in Rio de Janeiro, an important endemic area. There is a trend on increasing rates of hospitalizations and in-hospital deaths mainly in the Metropolitan belt.

The World Health Organization, in response to the growing burden of fungal disease, established a process to develop a fungal pathogen priority list. This systematic review aimed to evaluate the epidemiology and impact of infections caused by Talaromyces marneffei, Coccidioides species, and Paracoccidioides species. PubMed and Web of Sciences databases were searched to identify studies published between 1 January 2011 and 23 February 2021 reporting on mortality, complications and sequelae, antifungal susceptibility, preventability, annual incidence, and trends. Overall, 25, 17, and 6 articles were included for T. marneffei, Coccidioides spp. and Paracoccidioides spp., respectively. Mortality rates were high in those with invasive talaromycosis and paracoccidioidomycosis (up to 21% and 22.7%, respectively). Hospitalization was frequent in those with coccidioidomycosis (up to 84%), and while the duration was short (mean/median 3-7 days), readmission was common (38%). Reduced susceptibility to fluconazole and echinocandins was observed for T. marneffei and Coccidioides spp., whereas >88% of T. marneffei isolates had minimum inhibitory concentration values ≤0.015 µg/ml for itraconazole, posaconazole, and voriconazole. Risk factors for mortality in those with talaromycosis included low CD4 counts (odds ratio 2.90 when CD4 count <200 cells/µl compared with 24.26 when CD4 count <50 cells/µl). Outbreaks of coccidioidomycosis and paracoccidioidomycosis were associated with construction work (relative risk 4.4-210.6 and 5.7-times increase, respectively). In the United States of America, cases of coccidioidomycosis increased between 2014 and 2017 (from 8232 to 14 364/year). National and global surveillance as well as more detailed studies to better define sequelae, risk factors, outcomes, global distribution, and trends are required.

The impact of COVID-19 on paracoccidioidomycosis (PCM) in Argentina and the consequences generated by the pandemic are discussed. From 2018 to 3 years after the pandemic declaration, 285 proven PCM patients were registered. No association between both diseases was documented. PCM frequency decreased to extremely low levels in 2020. Mandatory social isolation and the emotional and psychological effects generated under pandemic circumstances led to delays in diagnosis, severe disseminated cases, and other challenges for diagnosis in subsequent years. Probable underdiagnosis should be considered due to the overlap of clinical manifestations, the low index of suspicion and the lack of sensitive diagnostic tools.

BACKGROUND: Paracoccidioidomycosis (PCM) is the leading cause of death among systemic mycoses in Brazil. On the other hand, oral squamous cell carcinoma (OSCC) is the most prevalent malignant neoplasm of the mouth. Both lesions rarely affect the tongue dorsum and may share similar clinical characteristics. This study aimed to retrieve cases of single oral ulcers diagnosed as PCM or OSCC. MATERIAL AND METHODS: A cross-sectional retrospective study was conducted. All patients who had a single ulcer on dorsum of the tongue and confirmed diagnosis of PCM or OSCC were evaluated. RESULTS: A total of 9 patients (5 women and 4 men) were evaluated, 5 patients had OSCCs (mean age = 69,8 years old), and 4 patients PCM (mean age = 51 years old). Most of the lesions were infiltrated and indurated in the palpation exam. Duration ranged from 1 to 12 months (mean time of 5.2 months and 4.7 months for OSCC and PCM, respectively). OSCC was the main clinical diagnosis hypothesis. CONCLUSIONS: Although uncommon, PCM and OSCC should be considered as a differential diagnosis hypothesis in infiltrated ulcers on the tongue dorsum. Incisional biopsy is mandatory to confirm the diagnosis and indicate the appropriate treatment.

Paracoccidioidomycosis is an infection with the potential for environmental dissemination, especially in regions of hot and humid climate, where human cases have been recorded in the Southwestern Amazon of Brazil, specifically in the state of Acre. Despite studies providing information about the presence of these fungi in soil and animal samples, such as armadillos, further investigations are still needed to determine the epidemiological distribution of the genus Paracoccidioides. The aim of this study was to detect the occurrence of Paracoccidioides fungi in the Southwestern Amazon. To achieve this, 60 soil samples were collected from armadillo burrows on rural properties in the in the municipalities of Acrelândia, Bujari, Plácido de Castro, Rio Branco, Sena Madureira, and Senador Guiomard, located in the state of Acre, Brazil. Fungal DNA was extracted from these samples using the DNEASY® PowerSoil kit-Quiagen, followed by Nested PCR technique with ITS4 and ITS5 as external primers, and PBITS-E and PBITS-R as internal primers. DNA amplification products of about 380 bp compatible with Paracoccidioides spp. were detected in six samples (10%), being sequenced and identified as P. brasiliensis. These findings indicate that the soils of the Acre state could be considered a potential source for Paracoccidioides spp., suggesting that local infections are likely.

BACKGROUND Paracoccidioidomycosis (PCM) is a systemic mycosis endemic to Latin America. Etiological agents are Paracoccidioides species that diverge phylogenetically throughout South America. OBJECTIVES This study aimed to document the epidemiology of PCM in Venezuela. METHODS We have performed a retrospective cross-sectional descriptive study in 31,081 clinical records of patients from two reference centres during 65 years (1954-2019). FINDINGS PCM diagnosis was confirmed in 745 patients. Chronic PCM was the most prevalent form (90.06% cases); 80.67% were male and the most affected age range was 41-60. Farming and construction were the most prevalent occupation and Miranda State had a higher prevalence. Lung and skin were the most affected organs, followed by oral manifestations. Direct examination, culture and serology showed a high sensibility, and no statistical difference was observed among the diagnostic tools. Out of 17 Paracoccidioides isolates genotyped from Venezuela, one was typed as Paracoccidioides americana and 16 as Paracoccidioides venezuelensis. MAIN CONCLUSIONS Clinical manifestations observed, information about the epidemiology and molecular profile is essential not only for diagnosis but also for understanding therapeutic responses to mycotic drugs and prognosis. Therefore, it is necessary to sequence all positive isolated strains in order to confirm the dominance of P. venezuelensis in Venezuela.

Paracoccidioidomycosis is a systemicmycosis caused by the Paracoccidioides brasiliensis fungus, which is endemic in Latin America. Brazil is the country with the highest number of cases. The affection of the central nervous system (CNS), a potentially fatal condition, occurs in 12% of the cases. The following forms of presentation are identified:meningeal, which is unusual;meningoencephalitic; and pseudotumoral, the latter two being more frequent. Imaging tests are essential for the diagnosis, but the histological identification of the fungus is required for confirmation of the pathology. The clinical picture depends on the neuraxial location.We present a case of amale rural worker, with expansive lesions in the CNS compatible with paracoccidioidomycosis.

Background and Objectives: Paracoccidioidomycosis (PCM) is a systemic disease caused by the dimorphic fungus Paracoccidioides brasiliensis found in the tropical and subtropical regions of Latin America. This study aimed to perform a retrospective analysis of PCM cases from the northern region of Rio Grande do Sul, Brazil. Methods: A total of 200 records of PCM cases diagnosed at the local reference pathology laboratory from 1995 to 2015 were analyzed Results: Of the patients, 185 were male and 15 female. Patients ranged in age from 31 to 80 years, the largest pro portion ( being aged between 51 and 60 years and living or working in the countryside. Clinical samples were mostly obtained from the oral cavity, followed by the oropharynx, lungs, brain, skin, and prostate. Conclusion: PCM is endemic in the south o f Brazil, as the local economy is largely based on agricultural activities, favoring the contact of the population with P. brasiliensis . Due to the great similarity between PCM symptoms and other respiratory diseases, the differential diagnosis is essentia l for the correct treatment of the disease and to avoid its progression.(AU)

Con el objetivo de describir las características clínico-epidemiológicas de la paracoccidioidomicosis, se realizó un estudio descriptivo de los casos diagnosticados por el Servicio de Microbiología Clínica del hospital de adultos Dr. Julio C. Perrando, de la ciudad de Resistencia (Chaco, Argentina). Entre 2011 y 2014 se detectaron 46 casos. En 2013 y 2014 se constató un incremento de la tasa de incidencia de alrededor de 4 veces con respecto a los anos anteriores. La forma crónica fue la predominante, con una media de edad de los pacientes de 53 anos. Del total de ellos, a 39 se les realizaron pruebas serológicas. En 15 de 39 casos, las pruebas serológicas fueron la única herramienta diagnóstica, mientras que en 4 de estos casos con diagnóstico microbiológico, la prueba resultó no reactiva. La inclusión de la paracoccidioidomicosis en el diagnóstico diferencial de pacientes de áreas endémicas que presentan un síndrome infeccioso inespecífico y la aplicación de las herramientas diagnósticas disponibles contribuyen al diagnóstico oportuno, así como a disminuir las secuelas de esta afección y su impacto socioeconómico.
In order to describe the clinical and epidemiological characteristics of paracoccidioidomycosis, a descriptive study of all the cases diagnosed by the Clinical Microbiology Service at Dr. Julio C. Perrando hospital in the city of Resistencia (Chaco Province, Argentina) was conducted. Between 2011 and 2014, 46 cases were detected. In the period 2013-2014, an almost 4-fold increase in the incidence rate was detected. The chronic form of the disease was predominant with an average age of 53 years. Serological tests in 39 out of 46 patients were performed. In 15 of 39 patients, serological tests were the only diagnostic tool while in 4 patients with a microbiological diagnosis serological tests were non-reactive. In patients from endemic areas with non-specific infectious syndrome it is important to include paracoccidioidomycosis in the differential diagnosis and to apply all available diagnostic tools to reach a timely diagnosis and to reduce the long-term sequelae and their socio-economic impact.

La paracoccidioidomicosis es una micosis sistemática, endémica de amplias regiones de América Latina, causada por un hongo termodimorfo, Paracoccidioides brasiliensis. Afecta de manera predominante a individuos de mediana edad y sexo masculino, en particular aquellos que cumplen tareas rurales. la infección se adquiere por vía inhalatoria, y puede diseminarse por vía hemática a diversos órganos y tejidos. La enfermedad puede evolucionar en forma aguda, subaguda o crónica. El diagnóstico presuntivo de la paracoccidioidomicosis se sustenta en los antecedentes epidemiológicos del paciente y en las manifestaciones clínicas. El diagnóstico etiológico clásico consiste en la visualización, el aislamiento y la identificación del agente causal, o bien el empleo de pruebas serológicas para determinar la presencia de anticuerpos específicos en sangre. Se presentan tres casos de paracoccidioidomicosis en pacientes varones, dos con formas agudas de la enfermedad y el restante con una forma crónica. En todos los casos, el diagnóstico se efectuó por los hallazgos de la microscopia, los cultivos y las pruebas serológicas
Paracoccidioidomycosis is a systemic mycosis, endemic to large regions of Latin America, caused by a thermodimorphic fungus, Paracoccidioides brasiliensis. It predominantly affects middle-aged and male individuals, particularly those who perform rural tasks. The infection is acquired by inhalation, and it can spread by blod to various organs and tissues. The disease can evolve in acute, subacute or chronic form. The presumptive diagnosis of paracoccidiodomycosis is based on the patient's epidemiological history and clinical manifestations. The classic etiological diagnosis consists of visualization, isolation and identification of the causative agent, or the use of serological tests to determine the presence of specific antibodies in the blood. There are threee cases of paracoccidioidomycosis in male patients, two with acute forms of the disease and the remaining with a chronic form. In all cases, the diagnosis was made by the findings of microscopy, cultures and serological tests

SUMMARYThe epidemiological characteristics of paracoccidioidomycosis were reviewed and updated. The new endemic areas in Brazil were discussed in the section regarding the geographic distribution of the mycosis. Subclinical infection with Paracoccidioides brasiliensis was discussed on the basis of skin test surveys with antigens of the fungus, seroepidemiological studies, and disease cases outside Latin America. Large case series permitted a comparison of the prevalence of the mycosis in different regions, its estimated incidence and risk factors for the development of the disease. Aspects modulating the expression of the clinical forms of paracoccidioidomycosis are also presented. This review also deals with diseases associated with the mycosis, opportunistic paracoccidioidomycosis, lethality, mortality and infection and disease in animals.

Paracoccidioides brasiliensis is the etiological agent of the major systemic mycosis in Brazil, called paracoccidioidomycosis. Although the Rio Grande do Sul is considered an endemic area of the disease, there are few studies on the ecology of P. brasiliensis in the state. Therefore, this study aimed to evaluate the infection of P. brasiliensis in horses from the mesoregion of Southwest Riograndense, using these animals as sentinels. Serological techniques, such as double immunodiffusion in agar gel (AGID) and indirect ELISA, were performed to detect the anti-gp43 P. brasiliensis antibody in horses from five different farms in the region of Bagé, RS, Brazil. Serology was performed in 200 Pure Blood English horses up to two years of age that were born and raised exclusively at the farms. Of these horses, 12% had anti-gp43 antibodies according to the ELISA results, with rates ranging from 0 to 30% according to the farm of origin (p < 0.001). Based on the immunodiffusion results, all equine serum samples were negative. These results indicate the presence of the fungus P. brasiliensis in the middle region of the southwestern state of Rio Grande do Sul, Brazil.

Paracoccidioidomycosis (PCM) is caused by dimorphic fungi from theParacoccidioides brasiliensis complex. Previous studies have demonstrated that the severity of disease is associated with a T-helper 2 immune response characterised by high interleukin (IL)-4 production. In the present study we analysed two polymorphisms in the IL-4gene (-590 C/T and intron-3 microsatellite) in 76 patients with PCM and 73 control subjects from an endemic area. The production of IL-4 by peripheral blood mononuclear cells after antigen or phytohaemagglutinin stimulation was determined by ELISA. A significant correlation was observed between the RP2/RP2 intron-3 genotype and infection with Paracoccidioides sp.(p = 0.011), whereas the RP1/RP1 genotype was correlated with resistance. No significant correlation was observed for the IL-4promoter polymorphism. Furthermore, the low IL-4 expression observed in the control group compared with patients was associated with the RP1/RP1 genotype. These results suggest that IL-4polymorphisms might be associated with the ability of the host to control Paracoccidioides sp.infection. The relevance of this polymorphism is supported by the observation that patients with disease produce high levels of IL-4 following mitogen or antigen stimulation. The IL-4gene is located in the cytokine cluster region of chromosome 5 where other polymorphisms have also been described.

A paracoccidioidomicose (PCM), doença provocada pelo Paracoccidioidis brasiliensis, é a mais importante micose profunda existente na América Latina. Foi descrita inicialmente no Brasil em 1908 por Adolfo Lutz, comcontribuições posteriores de relevância, para seu entendimento, de Splendore e Almeida. Pode acometer pessoas de todas as faixas etárias, evoluindo de forma aguda-subaguda ou crônica, respectivamente, em crianças-adolescentes e adultos após os 30 anos de idade. Possui desde manifestações benignas até formas graves com risco de morte. Apresenta anatomopatologicamente caráter granulomatoso e supurativo, acometendo principalmente os pulmões, mucosas das vias aéreas superiores e boca, pele e linfonodos, podendo afetar todos os órgãos e sistemas.

With the objective to evaluate the behavior of paracoccidioidomycosis in the last three decades, clinical and epidemiological data of 595 patients admitted to clinical services of the Federal University of Mato Grosso do Sul from 1980 to 2009 were investigated. Gender, age distribution, clinical form, comorbidity with tuberculosis or AIDS, and mortality were compared by decades of clinical admission. It was shown that during the three decades there was a decrease in women percentage, and the same manner occurred a reduction in participants in the age group of 20 to 39 years. Moreover, the acute/subacute forms have been diminished in the period. These fluctuations are closely related and can be simultaneously analyzed. Increased AIDS co-infection prevalence from the first to the second decade was also revealed, coinciding with the appearance of the retroviral epidemic and stabilizing during the third decade. No change in the tuberculosis co-infection rate was observed (overall = 6.9%). It reinforces the importance of this co-morbidity. The overall mortality rate remained steady at 6.7%, not varying significantly from one decade to another. The persistent mortality rate calls attention to the importance of this neglected disease.
Com o objetivo de avaliar o comportamento da paracoccidioidomicose nas últimas três décadas, dados clínicos e epidemiológicos de 595 pacientes atendidos dentre 1980 a 2009 no Hospital da Universidade Federal de Mato Grosso do Sul foram estudados. Sexo, faixa etária, forma clínica, associação com tuberculose ou AIDS e mortalidade foram comparados por década em que a doença foi diagnosticada. Observou-se, nas três décadas do estudo, uma redução do percentual de mulheres, de pacientes do grupo de 20 a 39 anos, assim como de casos com a forma aguda/subaguda. Estas alterações estão intimamente relacionadas e podem ser analisadas simultaneamente. Houve aumento de casos de coinfecção com AIDS da primeira para segunda década, coincidindo com o surgimento da epidemia, e manteve-se estável durante a década seguinte. Não houve alteração da taxa de coinfecção com tuberculose, que no geral foi de 6,9% o que reforça a importância desta comorbidade. A taxa geral de mortalidade foi de 6,7% e também não variou entre as décadas estudadas. A manutenção da taxa de óbitos chama a atenção para a relevância dessa doença negligenciada.

El panorama epidemiológico de la esporotricosis y la paracoccidioidomicosis en Perú y Latinoamérica es esporádico, fragmentario, y geográficamente limitado, debido principalmente a la falta de notificación obligatoria y a la escasa cobertura diagnóstica. Sin embargo, los aportes de investigaciones relacionados a entender la interacción de estos hongos, la respuesta del huésped y el ambiente, como el uso de un análisis espacial que relacione la distribución de estas micosis, la densidad poblacional y el clima, contribuyen o están encaminadas, al diseño de medidas de prevención y control de estas micosis y propone el manejo de mapas de riesgo epidemiológicos, a partir del hábitat del hongo, por los médicos, los turistas y las personas que viven en zonas rurales, donde estas micosis son endémicas. El objetivo del artículo es presentar una revisión del tema mediante resultados de investigaciones que contribuyen a la prevención y control de estas micosis.
The epidemiological picture of sporotrichosis and paracoccidioidomycosis in Peru and Latin America is sporadic, fragmented, and geographically limited, mainly due to lack of mandatory reporting and limited diagnostic coverage. However, research contributions related to understanding the interaction of these fungi, the response of the host and the environment, the use of spatial analysis that relates the distribution of these mycoses, population density and climate, contributes to the design of prevention and control strategies of these mycosis and suggest epidemiological risk maps management, based on the habitat of the fungus. This information will be used by doctors, tourists and people living in rural areas where mycoses are endemic. The aim of the paper is to present a review of the topic through research findings that contribute to the prevention and control of these mycosis.
