Saliva-Controlled Sputum Culture (SSC) - A High Value Diagnostic Tool For Deep Pulmonary Infections.

Authors:
Inna Gitelman

J Microbiol Methods 2020 Jul 2:105986. Epub 2020 Jul 2.

Faculty of Health Sciences, Ben Gurion University of the Negev, Beer Sheva, Israel. Electronic address:

A major obstacle to prompt diagnosis of fungal pulmonary infections is that deep sputum samples are scarce, yet are frequently rejected if they contain saliva. We show that including saliva controls unfailingly distinguishes oropharyngeal flora from pulmonary fungi, thus preserving valuable samples for analysis, expediting diagnoses and improving patient care.

Preclinical evaluation of acylhydrazone SB-AF-1002 as a novel broad-spectrum antifungal agent.

Antimicrob Agents Chemother 2020 Jun 29. Epub 2020 Jun 29.

Department of Microbiology and Immunology, Stony Brook University, Stony Brook, New York, USA

The incidence of invasive fungal infections is rising due to the increase in susceptible populations. Current clinically available drugs have therapeutic limitations due to toxicity, narrow spectrum of activity, and more importantly for the consistent rise of fungal species that are intrinsically resistant or develop resistance due to the prolonged therapy. Thus, there is an urgent need for new broad-spectrum antifungal agents with low toxicity and a novel mechanism of action. Read More

COVID-19 Associated Pulmonary Aspergillosis (CAPA)-From Immunology to Treatment.

J Fungi (Basel) 2020 Jun 24;6(2). Epub 2020 Jun 24.

Clinical and Translational Fungal-Working Group, University of California San Diego, La Jolla, CA 92093, USA.

Like severe influenza, coronavirus disease-19 (COVID-19) resulting in acute respiratory distress syndrome (ARDS) has emerged as an important disease that predisposes patients to secondary pulmonary aspergillosis, with 35 cases of COVID-19 associated pulmonary aspergillosis (CAPA) published until June 2020. The release of danger-associated molecular patterns during severe COVID-19 results in both pulmonary epithelial damage and inflammatory disease, which are predisposing risk factors for pulmonary aspergillosis. Moreover, collateral effects of host recognition pathways required for the activation of antiviral immunity may, paradoxically, contribute to a highly permissive inflammatory environment that favors fungal pathogenesis.

Department of Internal Medicine and Pediatrics, Ghent University, Ghent, Belgium.

Nowadays, reports in the literature support that patients with severe chronic obstructive pulmonary disease (COPD) are at higher risk to develop invasive pulmonary aspergillosis (IPA). However, the interpretation of -positive cultures from the airways in critically ill COPD is still a challenge. Indeed, as the patient could be merely colonized, tissue samples are required to ascertain IPA diagnosis but they are rarely obtained before death. Read More

Invasive Aspergillosis Masquerading as Multiple Pulmonary Nodules: A Challenging Diagnosis.

Cureus 2020 May 18;12(5):e8186. Epub 2020 May 18.

Internal Medicine, Rochester General Hospital, Rochester, USA.

Invasive pulmonary aspergillosis (IPA) is an aggressive fungal infection of the lungs characterized by tissue invasion by fungal hyphal elements. The definitive diagnosis is challenging because it relies on histopathological demonstration of fungal elements, and these days clinicians are relying more on bronchoalveolar lavage (BAL) cultures and serum biomarkers (galactomannan and beta-D-glucan). We would like to emphasize through our case the necessity to keep a high index of suspicion for IPA despite negative cultures and serum biomarkers in immunosuppressed patients and consider surgical biopsy early.

[Allergic bronchopulmonary aspergillosis].

Rev Med Suisse 2020 Jun;16(698):1250-1255

Service de pneumologie, Département de médecine, RHNE site de Pourtalès, 2000 Neuchâtel.

Allergic bronchopulmonary aspergillosis (ABPA) is a specific complex immunological response to the spores of Aspergillus fumigatus (Af) colonizing the bronchi of asthmatic or cystic fibrosis patients. Recurrent episodes of bronchial obstruction and inflammation, as well as mucoid impaction cause bronchiectasis, pulmonary infiltrates and fibrotic alterations of the lung parenchyma, resulting in significant morbidity and mortality. The pathogenesis of ABPA remains incompletely understood, so it is not clear why certain colonized subjects develop hypersensitivity to Af, and why some sensitized patients develop ABPA and others do not.

Eur Respir Rev 2020 Jun 16;29(156). Epub 2020 Jun 16.

Dept of Medicine, University of Alabama at Birmingham, Birmingham, AL, USA.

Cystic fibrosis transmembrane conductance regulator (CFTR) is an ion transporter that regulates mucus hydration, viscosity and acidity of the airway epithelial surface. Genetic defects in impair regulation of mucus homeostasis, causing severe defects of mucociliary clearance as seen in cystic fibrosis. Recent work has established that CFTR dysfunction can be acquired in chronic obstructive pulmonary disease (COPD) and may also contribute to other diseases that share clinical features of cystic fibrosis, such as asthma, allergic bronchopulmonary aspergillosis and bronchiectasis.

The National Aspergillosis Centre, Wythenshawe Hospital, Manchester University NHS Foundation Trust, Manchester, UK.

Chronic pulmonary aspergillosis (CPA) is a potentially life-threatening debilitating lung disease necessitating long-term oral antifungal treatment. However, development of antifungal-resistant isolates of Aspergillus and major toxicities requiring discontinuation of treatment limits their use. Intravenous (IV) antifungals are an option in this group of patients. Read More

Genetic variation and fungal infection risk: State of the art.

Curr Fungal Infect Rep 2019 Dec 27;13(4):250-259. Epub 2019 Nov 27.

Fungal Pathogenesis Section, Laboratory of Clinical Immunology & Microbiology (LCIM), National Institute of Allergy & Infectious Diseases (NIAID), National Institutes of Health (NIH), Bethesda, MD, USA.

Purpose Of Review: Fungal infections cause significant mortality in patients with acquired immunodeficiencies including AIDS, hematological malignancies, transplantation, and receipt of corticosteroids, biologics or small-molecule kinase inhibitors that impair key immune pathways. The contribution of several such pathways in antifungal immunity has been uncovered by inherited immunodeficiencies featuring profound fungal susceptibility. Furthermore, the risk of fungal infection in patients with acquired immunodeficiencies may be modulated by single nucleotide polymorphisms (SNPs) in immune-related genes. Read More

is an environmental fungus that can cause invasive pulmonary aspergillosis when spores are inhaled into the respiratory tract and invade airway or lung tissue. Influenza is a common respiratory virus that can cause severe respiratory disease, and postinfluenza invasive pulmonary aspergillosis, which is becoming a well-recognized clinical problem, typically occurs in critically ill patients. Mice challenged with influenza A PR/8/34 H1N1 and subsequently challenged with had increased fungal burden, viral burden, inflammation, and mortality compared with single infected mice. Read More

Gut Microbiota Abrogates Anti-α-Gal IgA Response in Lungs and Protects against Experimental Infection in Poultry.

Vaccines (Basel) 2020 Jun 7;8(2). Epub 2020 Jun 7.

UMR BIPAR, INRAE, ANSES, Ecole Nationale Vétérinaire d'Alfort, Université Paris-Est, 14 rue Pierre et Marie Curie, 94706 Maisons-Alfort, France.

Naturally occurring human antibodies (Abs) of the isotypes IgM and IgG and reactive to the galactose-α-1,3-galactose (α-Gal) epitope are associated with protection against infectious diseases, caused by pathogens expressing the glycan. Gut microbiota bacteria expressing α-Gal regulate the immune response to this glycan in animals lacking endogenous α-Gal. Here, we asked whether the production of anti-α-Gal Abs in response to microbiota stimulation in birds, confers protection against infection by , a major fungal pathogen that expresses α-Gal in its surface.
