Paracoccidioidomycosis is a common deep fungus infection in South America, particularly in Brazil. It is acquired through inhalation and primary involvement of lungs. Subsequently, dissemination may occur and oral mucosa is frequently affected and actually, in most of the cases the diagnosis is established because of the oral lesions. Thus, the role of the dentist is fundamental to correct diagnosis. However, the involvement of intestine is rarely reported. The current case describes a 36-year-old man who presented abdominal pain and intestinal constipation, being suspected and then confirmed as paracoccidioidomycosis after already be diagnosed with this disease by a dentist through oral manifestations...

Endemic mycoses are systemic fungal infections. Histoplasmosis is endemic in all temperate areas of the world; coccidioidomycosis and paracoccidioidomycosis are only present in the American continent. These pathogens are not present in Spain, but in the last years there has been an increase of reported cases due to migration and temporary movements. We obtained from the Spanish hospitals records clinical and demographic data of all hospitalized cases between 1997 and 2014. There were 286 cases of histoplasmosis, 94 of Coccidioidomycosis and 25 of paracoccidioidomycosis...

A prospective study was performed in 200 paracoccidioidomycosis (PCM) patients, 51 presenting the acute/subacute form (AF) and 149 the chronic form (CF), submitted to the evaluation of the hepatobiliary system at admission and during the follow-up treatment with cotrimoxazole (CMX) or itraconazole (ITC). This study aimed to better evaluate the involvement of the hepatobiliary system in PCM and the effect of these antifungal compounds on this system. Serum levels of direct bilirubin (DB), total bilirubin (TB), aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), and gamma-glutamyl transferase (GGT) were evaluated...

Itraconazole (ITC) is the drug of choice for treating paracoccidioidomycosis (PCM); nonetheless, patients with the chronic form of this mycosis develop fibrosis, a residual pulmonary abnormality, even after treatment. Recently, we observed that the depletion of neutrophils with a specific monoclonal antibody (mAb-anti-Ly6G) during the chronic stages of PCM was associated with a decrease in the fungal burden, the inflammatory response and a reduction of fibrosis. Herein, we aimed to evaluate the effect of ITC in combination with the mAb-anti-Ly6G in an experimental model of pulmonary PCM...

BACKGROUND: Paracoccidioidomycosis (PCM) is one of the most important systemic mycoses in Latin America and the leading fungal cause of mortality in non-immunosuppressed individuals in Brazil. However, HIV/PCM co-infection can increase the clinical severity in these co-infected patients. This co-infection is rarely reported in the literature mainly because of the different epidemiological profiles of these infections. Furthermore, PCM is a neglected and non-notifiable disease, which may underestimate the real importance of this disease...

Paracoccidioides brasiliensis is the agent of paracoccidioidomycosis (PCM), a cause of disease in healthy and immunocompromised persons in Latin America. The infection begins after inhalation of the fungal propagules and their thermo-dimorphic shift to yeast form. The development of the disease depends on factors associated with the host immune response and the infectious agent's characteristics, especially virulence. The oxidative stress response is an important virulence attribute in several fungi. In this study, we assessed the enzymatic repertoire of responses to oxidative stress in the Pb18 isolate with different degrees of virulence...

Negative results in serological routine screening of patients with microbiologically proven PCM are occasionally reported. Failure in detecting anti-Paracoccidioides antibodies has been ascribed to factors either related to serological techniques or to the status of the host immune reactivity. Recently, this issue has been renewed by the recognition that the Paracoccidioides genera comprises two species, lutzii and brasiliensis, which have distinct antigenic profiles and, therefore, may elicit different host antibody responses...

Paracoccidioidomycosis is a systemic fungal infection affecting mainly Latin American countries that is caused by Paracoccidioides brasiliensis and Paracoccidioides lutzii. During the study of fungal pathogenesis, in vivo studies are crucial to understand the overall mechanisms involving the infection as well as to search for new therapeutic treatments and diagnosis. Caenorhabditis elegans is described as an infection model for different fungi species and a well-characterized organism to study the innate immune response...

Argentina has two endemic areas of paracoccidioidomycosis (PCM). Bordering Paraguay and Brazil, Northeast Argentina (NEA) comprises the area with the highest incidence where the chronic adult clinical form has historically been reported. Juvenile form in children and adolescents is rare in this area since only one case was reported in the last 10 years. Despite this, between 2010 and 2012, several cases of acute/subacute clinical forms in children aged 10 to 16 (median 12) were detected. In the last decade, the NEA region has been exposed to ecological variations as consequences of certain climatic and anthropogenic changes, including El Niño-Southern Oscillation phenomenon during 2009, and deforestation...

Resistance to primary fungal pathogens is usually attributed to the proinflammatory mechanisms of immunity conferred by interferon-γ activation of phagocytes that control microbial growth, whereas susceptibility is attributed to anti-inflammatory responses that deactivate immunity. This study challenges this paradigm by demonstrating that resistance to a primary fungal pathogen such as Paracoccidiodes brasiliensis can be mediated by disease tolerance, a mechanism that preserves host fitness instead of pathogen clearance...

BACKGROUND: Cutaneous leishmaniasis is distributed worldwide, including Brazil. Its several clinical forms need to be distinguished from other dermatoses. Clinical similarities and lack of a gold standard diagnostic tool make leishmaniasis-like lesions a challenging diagnosis. OBJECTIVES.: To report the final diagnosis of patients primarily suspected of having American tegumentary leishmaniasis (ATL). METHODS.: A retrospective cross-sectional study was conducted on the basis of medical records of 437 patients with clinical suspicion of ATL, registered in electronic hospital system between 1980 and 2013...

Two distinct patterns of immune recovery inflammatory syndrome (IRIS) are recognized, paradoxical and unmasking IRIS. Here we raise some concerns regarding the first case of neuroPCM-IRIS published to date, as recently proposed by Almeida and Roza (Mycopathologia 177:137-141, 2017) for a patient originally described by Silva-Vergara et al. (Mycopathologia 182:393-396, 2014), taking in account the different case definitions for IRIS and the cases of neuroparacoccidioidomycosis already described in the literature...

Paracoccidioidomycosis (PCM) is a fungal disease caused by Paracoccidioides spp., which can cause a systemic granulomatous infection with tegumentary and visceral involvement. Sarcoid-like skin lesions are uncommon and can be misdiagnosed due to similarities with other granulomatous diseases. We report a case of a women presenting with erythematous infiltrated plaques on her face that was treated for leprosy and rosacea with no response and was later diagnosed with PCM, presenting positive serology for Paracoccidioides lutzii...

BACKGROUND: The main clinical forms of paracoccidioidomycosis (PCM) are the acute/subacute form (AF) and the chronic form (CF), and they both display considerable clinical variability. The immune responses of PCM patients, during and after treatment, remain neglected, mainly in the case of CF patients, due to the high prevalence of pulmonary sequelae. OBJECTIVE: To evaluate the distribution of whole blood T cell subsets, serum cytokines, and biomarkers of pulmonary fibrosis in PCM patients, according to the clinical form and at different time points, during the antifungal therapy...

Transmission of Paracoccidioides spp. fungi to humans is usually related to manipulation of soil. Rural workers are the most affected group. We report an outbreak of paracoccidioidomycosis after deforestation and massive earth removal during construction of a highway in Rio de Janeiro, Brazil. Extensive environmental disturbances might be involved in fungal transmission.
