Endemic Fungi Presenting as Community-Acquired Pneumonia: A Review.

Semin Respir Crit Care Med 2020 Aug 6;41(4):522-537. Epub 2020 Jul 6.

Indiana University, School of Medicine, Pulmonary Critical Care Medicine, Thoracic Transplantation Program, Indianapolis, Indiana.

In endemic areas, dimorphic fungal infections due to , and account for up to 30% of cases of community-acquired pneumonia. Because respiratory manifestations are often indistinguishable from common bacterial causes of pneumonia, the diagnosis of pulmonary histoplasmosis, blastomycosis, and coccidioidomycosis is often delayed and associated with antibiotics overuse. In addition to being highly endemic to certain regions of North America, dimorphic fungi have global significance due to established areas of endemicity in all six inhabited continents, an increasingly interconnected world of travelers and transported goods, and a changing epidemiology as a result of global heating and anthropomorphic land utilization.

Endemic mycoses: epidemiology and diagnostic strategies.

Expert Rev Anti Infect Ther 2020 Jul 3. Epub 2020 Jul 3.

Dermatology service. Hospital General de México "Dr. Eduardo Liceaga".

Introduction: The global frequency of endemic mycoses has considerably increased, mainly due to environmental changes, population growth in endemic areas, and the increase in HIV-related immunosuppressed status. Among the most frequent endemic mycoses are coccidioidomycosis in semi-desert climates, and paracoccidioidomycosis, and histoplasmosis in tropical climates. The inoculum can enter the host through the airway or directly through the skin. Read More

Close encounters of three kinds: Case-based report of endemic mycoses in the environs of New York city.

Respir Med Case Rep 2020 30;30:101106. Epub 2020 May 30.

Division of Pulmonary, Critical Care and Sleep Medicine, Westchester Medical Center, Valhalla, NY, USA.

The term "endemic mycoses" refers to a group of fungi that maintains a baseline rate of infection only in certain geographical regions due to the hospitable enviormental conditions these regions offer. In the United States, , , and are the three most prevalent endemic human fungal infections. The traditional endemic regions for these pathogens are defined based on data acquired many decades ago, and case detection is subject to diagnostic delays even in classically endemic areas, a problem that is likely to be magnified in areas less familiar with these fungal infections.

Disseminated blastomycosis.

IDCases 2020 14;21:e00786. Epub 2020 May 14.

University of Tabouk, Tabuk, Tabuk, Saudi Arabia.

Blastomycosis is a fungal infection caused by Blastomyces dermatitidis, a dimorphic fungus endemic in the soils of the Ohio and Mississippi River Vallys, Great Lakes region, and southeastern United States. It most commonly manifests as a pulmonary infection following inhalation of spores, which causes a broad array of clinical manifestations ranging from asymptomatic infection to fulminant sepsis with acute respiratory distress syndrome and death. Extrapulmonary disease occurs in approximately 25-30% of patients following hematogenous spread from the lungs, with skin being the most common site of exytrapulmonary disease. Read More

Department of Infectious Diseases, Cook County Health and Hospital System, Chicago, IL, USA.

Cutaneous blastomycosis is the most common extrapulmonary manifestation of disseminated blastomycosis, a disease caused by , a dimorphic fungus endemic of North America. Initially, the organism enters the respiratory system by inhalation of the infectious conidia and produces an acute pulmonary infection that may eventually disseminate if it is left untreated. Blastomycosis may represent a diagnostic challenge and its definitive diagnosis requires direct visualization of the distinctive yeast or a positive fungal culture. Read More

Int J Infect Dis 2020 May 1;96:187-191. Epub 2020 May 1.

Aspirus Wausau Hospital, Wausau, WI, USA.

Objectives: Diagnosing pulmonary blastomycosis (PB) requires the detection of Blastomyces dermatitidis in pulmonary secretions or tissue, which can be achieved via bronchoscopic procedures like bronchoalveolar lavage (BAL) or brush and transbronchial biopsy (TBBx). This descriptive study retrieved the data of PB that was diagnosed by bronchoscopy to define which bronchoscopic procedure produced the highest yield.

Blastomyces dermatitidis is a dimorphic fungus endemic to the United States and Canada. Although both Histoplasma and Blastomyces are found in similar geographic regions, Blastomyces is many times more likely to cause dissemination in the immunocompetent host, frequently involving the bone. However, given the indolent nature of this fungal infection and more prevalent bacterial etiologies of osteomyelitis, diagnosis and treatment are often significantly delayed. Read More

Re-drawing the Maps for Endemic Mycoses.

Division of Infectious Diseases, Department of Internal Medicine, University of Kansas, Kansas City, KS, USA.

Endemic mycoses such as histoplasmosis, coccidioidomycosis, blastomycosis, paracoccidioidomycosis, and talaromycosis are well-known causes of focal and systemic disease within specific geographic areas of known endemicity. However, over the past few decades, there have been increasingly frequent reports of infections due to endemic fungi in areas previously thought to be "non-endemic." There are numerous potential reasons for this shift such as increased use of immune suppressive medications, improved diagnostic tests, increased disease recognition, and global factors such as migration, increased travel, and climate change.

Blastomycosis is a subacute or chronic deep mycosis caused by a dimorphic fungus, Blastomyces dermatitidis, that generally produces a pulmonary form of the disease and, to a lesser extent, extrapulmonary forms, such as cutaneous, osteoarticular, and genitourinary. Both immunocompetent and immunocompromised individuals can be infected, but more severe disease occurs in the immunocompromised. Blastomycosis can be diagnosed by culture, direct visualization of the yeast in affected tissue, antigen testing, or a combination of these methods. Read More

is a thermally dimorphic fungus that can cause pulmonary, extrapulmonary, or disseminated infections. Though it can infect both immune-competent and immunocompromised hosts, the disease can be severe in immunocompromised hosts. Exposure to silica dust is associated with silicosis, and this is associated with impaired immunity and an increased risk of mycobacterial and fungal infections. Read More

Pulmonary Blastomycosis Following Eculizumab Therapy in a Lung Transplant Recipient.

Exp Clin Transplant 2020 Jun 11;18(3):410-413. Epub 2019 Oct 11.

From the Division of Respirology, Department of Medicine, University of Toronto, the Lung Transplant Program, Toronto General Hospital, University Health Network, Toronto, Ontario, Canada; and the Department of Thoracic Surgery, Institute of Development, Aging and Cancer, Tohoku University, Sendai, Japan.

Lung transplant recipients are at risk of developing many kinds of lung infection, such as community-acquired, nosocomial, opportunistic, and endemic. Here, we report a young lung transplant recipient who developed blastomycosis, which had most likely occurred following eculizumab treatment for atypical hemolytic uremia syndrome. We hypothesize that the agent interfering with C5 would influence the immune response against Blastomyces species. Read More

Blastomyces dermatitidis Antibody and Antigen Detection: Comparison of Four Lysate Antigens and Antibodies Prepared from Human Isolates from a Blastomycosis Outbreak.

Mycopathologia 2019 Oct 3;184(5):661-666. Epub 2019 Oct 3.

Department of Biological Sciences, Idaho State University, Pocatello, ID, USA.

Blastomycosis is a systemic fungal disease of humans and other animals produced by the thermally dimorphic fungal organism, Blastomyces dermatitidis. Recent studies have focused on the utilization of antibody and antigen detection in the development of immunoassays for the diagnosis of blastomycosis. This study was designed to evaluate four B.

Central Nervous System Blastomycosis With Multiple Brain Abscesses Presenting as Right Upper Extremity Weakness.

Neurohospitalist 2019 Oct 12;9(4):230-234. Epub 2019 Feb 12.

Division of Hospital Medicine, University of Kentucky Medical Center, Lexington, KY, USA.

Blastomycosis is a mycotic infection that typically affects the lung, but that can have dermatologic, orthopedic, genitourinary, and central nervous system manifestations. is a true human pathogen, which can produce disease in immunocompetent hosts. Risk factors for infection include residence in or travel to endemic areas and outdoor occupation, particularly those activities near open bodies of water and that disrupt soil. Read More
