Departamento de Imunologia, Instituto de Ciências Biomédicas, Universidade de São Paulo, São Paulo, Brazil.

Plasmacytoid dendritic cells (pDCs), which have been extensively studied in the context of the immune response to viruses, have recently been implicated in host defense mechanisms against fungal infections. Nevertheless, the involvement of human pDCs during paracoccidioidomycosis (PCM), a fungal infection endemic to Latin America, has been scarcely studied.

Lobomycosis-like disease in common bottlenose dolphins Tursiops truncatus from Belize and Mexico: bridging the gap between the Americas.

Dis Aquat Organ 2018 Mar;128(1):1-12

The Graduate Center, City University of New York, New York 10016, USA.

Lobomycosis and lobomycosis-like diseases (LLD) (also: paracoccidioidomycosis) are chronic cutaneous infections that affect Delphinidae in tropical and subtropical regions worldwide. In the Americas, these diseases have been relatively well-described, but gaps still exist in our understanding of their distribution across the continent. Here we report on LLD affecting inshore bottlenose dolphins Tursiops truncatus from the Caribbean waters of Belize and from the eastern tropical Pacific Ocean off the southwestern coast of Mexico.

Itraconazole in combination with neutrophil depletion reduces the expression of genes related to pulmonary fibrosis in an experimental model of paracoccidioidomycosis.

Med Mycol 2018 Jul;56(5):579-590

School of Microbiology, Universidad de Antioquia, Medellín, Colombia.

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. Read More

Negative results in serological routine screening of patients with microbiologically proven Paracoccidioidomycosis (PCM) are occasionally reported. Failure in detecting anti- 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 genera comprises two species, and , which have distinct antigenic profiles and, therefore, may elicit different host antibody responses.

Disease Tolerance Mediated by Phosphorylated Indoleamine-2,3 Dioxygenase Confers Resistance to a Primary Fungal Pathogen.

Front Immunol 2017 13;8:1522. Epub 2017 Nov 13.

Department of Immunology, Institute of Biomedical Sciences, University of São Paulo, São Paulo, Brazil.

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 can be mediated by disease tolerance, a mechanism that preserves host fitness instead of pathogen clearance. Among the mechanisms of disease tolerance described, a crucial role has been ascribed to the enzyme indoleamine-2,3 dioxygenase (IDO) that concomitantly controls pathogen growth by limiting tryptophan availability and reduces tissue damage by decreasing the inflammatory process.

Final diagnosis of 86 cases included in differential diagnosis of American tegumentary leishmaniasis in a Brazilian sample: a retrospective cross-sectional study.

An Bras Dermatol 2017 Sep-Oct;92(5):642-648

Division of Dermatology, Department of Medical Clinics, Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo (FMRP-USP) - Ribeirão Preto (SP), Brazil.

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. Read More

Opinion: Paracoccidioidomycosis and HIV Immune Recovery Inflammatory Syndrome.

Mycopathologia 2018 Jun 20;183(3):495-498. Epub 2017 Nov 20.

Laboratories of Medical Investigation Units #53 and #56, Medical School and Tropical Medicine Institute, University of São Paulo Medical School, Avenida Doutor Arnaldo 455, São Paulo, SP, Brazil.

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. Read More

A case of paracoccidioidomycosis due to presenting sarcoid-like form.

Med Mycol Case Rep 2018 Mar 25;19:6-8. Epub 2017 Sep 25.

Division of Infectious Diseases, Universidade Federal do Espírito Santo, Vitória 29043-900, Espírito Santo, Brazil.

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 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.

Oral paracoccidioidomycosis in a single-center retrospective analysis from a Brazilian southeastern population.

J Infect Public Health 2017 Nov 16. Epub 2017 Nov 16.

Department of Clinical Dentistry, Espírito Santo Federal University, Vitória, Brazil. Electronic address:

Background: Paracoccidioidomycosis (PCM) is the most prevalent endemic systemic fungal infection in Latin America. In Brazil, it stands out as the eighth-highest cause of mortality among chronic or recurrent infections and has the highest mortality rate among systemic mycoses. Oral mucosal lesions may be the first visible physical manifestation of the disease. Read More
