Sputum Inflammometry to Manage Chronic Obstructive Pulmonary Disease Exacerbations: Beyond Guidelines.

Tuberc Respir Dis (Seoul) 2020 Jul 18;83(3):175-184. Epub 2020 Jun 18.

Firestone Institute for Respiratory Health, St. Joseph's Healthcare Hamilton and the Department of Medicine, McMaster University, Hamilton, ON, Canada.

Quantitative sputum cytometry facilitates in assessing the nature of bronchitis associated with exacerbations of chronic obstructive pulmonary disease (COPD). This is not assessed in most clinical trials that evaluate the effectiveness of strategies to prevent or to treat exacerbations. While up to a quarter of exacerbations may be associated with raised eosinophil numbers, the vast majority of exacerbations are associated with neutrophilic bronchitis that may indicate airway infections.

Conserved T-cell epitopes of respiratory syncytial virus (RSV) delivered by recombinant live attenuated influenza vaccine viruses efficiently induce RSV-specific lung-localized memory T cells and augment influenza-specific resident memory T-cell responses.

Antiviral Res 2020 Jun 22:104864. Epub 2020 Jun 22.

Department of Virology, Institute of Experimental Medicine, Saint Petersburg, Russia. Electronic address:

Respiratory syncytial virus (RSV) can cause recurrent infection in people because it does not stimulate a long-lived immunological memory. There is an urgent need to develop a safe and efficacious vaccine against RSV that would induce immunological memory without causing immunopathology following natural RSV infection. We have previously generated two recombinant live attenuated influenza vaccine (LAIV) viruses that encode immunodominant T-cell epitopes of RSV M2 protein in the neuraminidase or NS1 genes.

Pulmonary delivery of ORMDL3 short hairpin RNA - a potential tool to regulate allergen-induced airway inflammation.

Exp Lung Res 2020 Jun 24:1-15. Epub 2020 Jun 24.

Department of Veterinary and Biomedical Sciences, University of Minnesota, St. Paul, MN, USA.

Exposure to various allergens has been shown to increase expression of ORMDL3 in the lung in models of allergic asthma. Studies using genetically modified (transgenic or knock out) mice have revealed some of the functions of ORMDL3 in asthma pathogenesis, although amid debate. The goal of this study was to use targeted post-transcriptional downregulation of in allergen-challenged wild-type (WT) mice by RNA interference to further elucidate the functional role of ORMDL3 in asthma pathogenesis and evaluate a potential therapeutic option.

The association between obesity and poor outcome after COVID-19 indicates a potential therapeutic role for montelukast.

Med Hypotheses 2020 May 27;143:109883. Epub 2020 May 27.

President British Obesity and Metabolic Surgery Society, Visiting Professor University of Chester, CEO Phoenix Health, United Kingdom. Electronic address:

It is widely believed that infection with the SARS-CoV-2 virus triggers a disproportionate immune response which causes a devastating systemic injury, particularly in individuals with obesity, itself a chronic, multi-organ inflammatory disease. Immune cells accumulate in visceral adipose tissue and together with paracrine adipocytes release a wide range of biologically active cytokines (including IL-1β, IL5, IL6 and IL8) that can result in both local, pulmonary and systemic inflammation. A more intense 'cytokine storm' is postulated as the mechanism behind the extreme immune response seen in severe COVID-19. Read More

Lung fibroblasts produce interleukin-33 in response to stimulation by retinoblastoma-binding protein 9 via production of prostaglandin E2.

Int Immunol 2020 Jun 3. Epub 2020 Jun 3.

Department of Immunology, Hyogo College of Medicine, Nishinomiya, Hyogo, Japan.

Intestinal nematode infection induces pulmonary eosinophilia via interleukin (IL)-33, although the mechanism of pulmonary IL-33 induction remains unclear. Because nematode migration damages lungs, we speculated that lung-derived damage-associated molecular patterns (DAMPs) possess an IL-33-inducing activity (IL33ia). Indeed, intranasal administration of a lung extract induced IL-33 production in lungs. Read More

Elevated Circulating Th2 Cells in Women With Asthma and Psychological Morbidity: A New Asthma Endotype?

Clin Ther 2020 Jun 29;42(6):1015-1031. Epub 2020 May 29.

Division of Pulmonary Medicine, Department of Medicine, Faculty of Medicine and Dentistry, University of Alberta, Edmonton, Alberta, Canada; Alberta Respiratory Centre, University of Alberta, Edmonton, Alberta, Canada.

Purpose: Psychological stress shifts the immune system toward the production of T-helper (Th)-2-mediated cytokines and eosinophilia, increases the risks for both asthma and depression, and can precipitate asthma exacerbations. Th2-mediated inflammation is a characteristic of allergic asthma. We have shown that the levels of CD4 Th2 cells in the peripheral blood of patients with asthma are associated with severity and/or control of the disease. Read More

Recognizing asthma in patients with chronic obstructive pulmonary disease.

J Am Assoc Nurse Pract 2020 May 21. Epub 2020 May 21.

Emory University, Nell Hodgson Woodruff School of Nursing, Atlanta, Georgia.

Newer guidelines for the use of inhaled corticosteroids in chronic obstructive pulmonary disease (COPD) state that they should be reserved for those patients who are likely to derive the greatest benefits from this medication class. This makes the latest Global Initiative for Chronic Obstructive Lung disease (GOLD) guidelines of great importance. This article examines the utility of a previous diagnosis of asthma, the presence of eosinophilia, elevated immunoglobulin E, and positive bronchodilator response in identifying the people with COPD who also have asthma, and it presents two case studies of patients with COPD to illustrate the use of the GOLD guidelines in clinical practice.

Medical Faculty of the Lazarski University in Warsaw, Poland.

The beneficial effects of low dose azithromycin on reducing the number of exacerbations in patients with chronic obstructive pulmonary disease (COPD) have been the subject of many clinical studies. Long-term administration of low dose azithromycin is known to suppress proinflammatory cytokine production, potentiate macrophage phagocytosis and anti-inflammatory cytokine expression. The effect of azithromycin is also associated with a decrease in the expression of human HLA (human leukocyte antigen) complex molecules in the respiratory tract, including HLA-A, HLA-B, HLA-DPA1, HLA-DRA, HLA-DRB4.

Eosinophilic Pneumonia and Lymphadenopathy Associated With Vaping and Tetrahydrocannabinol Use.

Pediatrics 2020 04;145(4)

Divisions of Pulmonary Medicine.

Idiopathic acute eosinophilic pneumonia is a rare and potentially life-threatening condition that is defined by bilateral pulmonary infiltrates and fever in the presence of pulmonary eosinophilia. It often presents acutely in previously healthy individuals and can be difficult to distinguish from infectious pneumonia. Although the exact etiology of idiopathic acute eosinophilic pneumonia remains unknown, an acute hypersensitivity reaction to an inhaled antigen is suggested, which is further supported by recent public health risks of vaping (electronic cigarette) use and the development of lung disease.

Canine eosinophilic pulmonary granulomatosis: case report and literature review.

J Vet Diagn Invest 2020 Mar;32(2):329-335

Department of Veterinary Pathology, Western College of Veterinary Medicine, University of Saskatchewan, Saskatoon, Saskatchewan, Canada. Current address: Tudor Glen Veterinary Hospital, St. Albert, Alberta, Canada (Abbott).

We describe and illustrate herein a case of eosinophilic pulmonary granulomatosis (EPG) in a 16-mo-old, castrated male, Great Pyrenees crossbred dog. EPG appears to differ from eosinophilic pneumonias and eosinophilic bronchopneumopathy in dogs by the presence of nodules and masses in the lungs composed of eosinophils, macrophages, and various combinations of lymphocytes, plasma cells, neutrophils, and mast cells within fibrous tissue. Specific information from this dog was added to the information from the limited number of other dogs diagnosed with EPG reported in the veterinary literature, and the information analyzed.

Relationship of Blood Eosinophils with Fractional Exhaled Nitric Oxide and Pulmonary Function Parameters in Chronic Obstructive Pulmonary Disease (COPD) Exacerbation.

Med Sci Monit 2020 Mar 12;26:e921182. Epub 2020 Mar 12.

Department of Respiratory Medicine, Jiangxi Provincial People's Hospital Affiliated to Nanchang University, Nanchang, Jiangxi, China (mainland).

BACKGROUND The 2018 Global Initiative for Chronic Obstructive Lung Disease Report reveals that the blood eosinophil count could forecast the risk of flare-ups. This study explored the correlations of blood eosinophils with fractional exhaled nitric oxide (FeNO) and pulmonary function parameters in acute exacerbation of chronic obstructive pulmonary disease (AECOPD). MATERIAL AND METHODS The data of patients with AECOPD at our hospital admitted between July 2018 and June 2019 were retrospectively analyzed. Read More

Acute Eosinophilic Pneumonia: A Rare Complication of Daptomycin Therapy.

Cureus 2020 Jan 28;12(1):e6803. Epub 2020 Jan 28.

Internal Medicine, University of North Dakota School of Medicine, Fargo, USA.

Daptomycin is a cyclic lipopeptide antibiotic with great efficacy targeting gram-positive cocci, including methicillin-resistant Staphylococcus aureus and vancomycin-resistant enterococcus. Acute eosinophilic pneumonia is a rare complication of daptomycin therapy, with a poorly understood etiology thought to involve the accumulation of the drug in pulmonary surfactant inducing inflammation. We present a 56-year-old male with a history of spinal epidural abscess being treated with intravenous daptomycin, who presented to the emergency department with fever, developed worsening shortness of breath, and was subsequently discovered to have eosinophilia of pulmonary secretions via bronchoalveolar lavage.

Insulin Modulates the Immune Cell Phenotype in Pulmonary Allergic Inflammation and Increases Pulmonary Resistance in Diabetic Mice.

Front Immunol 2020 11;11:84. Epub 2020 Feb 11.

Laboratory of Immunoendocrinology, Department of Clinical and Toxicological Analyses, School of Pharmaceutical Sciences, University São Paulo (FCF/USP), São Paulo, Brazil.

Reports have shown that the onset of diabetes mellitus (DM) in patients previously diagnosed with asthma decreases asthmatic symptoms, whereas insulin aggravates asthma. The present study evaluated the modulatory effect of insulin on the development of allergic airway inflammation in diabetic mice. To evaluate the effects of relative insulin deficiency, an experimental model of diabetes was induced by a single dose of alloxan (50 mg/kg, i. Read More
