The complex pathophysiology of allergic rhinitis: scientific rationale for the development of an alternative treatment option.

Allergy Asthma Clin Immunol 2019 16;15:24. Epub 2019 Apr 16.

5Department of Environmental Medicine, Karolinska Institutet, 171 77 Stockholm, Sweden.

Allergic rhinitis (AR) poses a global health problem and can be challenging to treat. Many of the current symptomatic treatments for AR have been available for decades, yet there has been little improvement in patient quality of life or symptom burden over the years. In this review, we ask why this might be and explore the pathophysiological gaps that exist within the various AR treatment classes. Read More

The role of invariant T cells in inflammation of the skin and airways.

Semin Immunopathol 2019 Apr 15. Epub 2019 Apr 15.

Centre for Cancer Biology, The University of South Australia and SA Pathology, North Terrace, Adelaide, SA, 5000, Australia.

Invariant and semi-invariant T cells are emerging as important regulators of host environment interactions at barrier tissues such as the airway and skin. In contrast to conventional T cells, invariant natural killer T (iNKT) cells and mucosal associated invariant T (MAIT) cells express T cell receptors of very limited diversity. iNKT and MAIT cells recognise antigens presented by the MHC class 1-like monomorphic molecules CD1d and MR1, respectively.

Thinking bigger: How early life environmental exposures shape the gut microbiome and influence the development of asthma and allergic disease.

Allergy 2019 Apr 9. Epub 2019 Apr 9.

Department of Pediatrics, British Columbia Children's Hospital, The University of British Columbia, Vancouver, BC, Canada.

Imbalance, or dysbiosis, of the gut microbiome of infants has been linked to an increased risk of asthma and allergic diseases. Most studies to date have provided a wealth of data showing correlations between early-life risk factors for disease and changes in the structure of the gut microbiome that disrupt normal immunoregulation. These studies have typically focused on one specific risk factor, such as mode of delivery or early-life antibiotic use. Read More

Different phenotypes and factors associated with atopic dermatitis in the young adult Singaporean Chinese population: A cross-sectional study.

World Allergy Organ J 2019 26;12(1):100008. Epub 2019 Jan 26.

Department of Biological Science, National University of Singapore, Singapore.

Background: Atopic dermatitis (AD) is a chronic allergic disease typically accompanied by atopy and thus, a tendency to develop allergic diseases such as allergic rhinitis, asthma or food allergies. Currently, individuals with AD are classified into those presenting with AD alone and those presenting with AD along with other allergic diseases (AD+). It is important to identify the various endophenotypes of AD using anthropometric, environmental, socio-economic, and disease history data in order to improve disease management. Read More

Epithelial cell-derived cytokines: more than just signaling the alarm.

J Clin Invest 2019 Apr 1;129(4):1441-1451. Epub 2019 Apr 1.

Immunology Program, Benaroya Research Institute at Virginia Mason, Seattle, Washington, USA.

The epithelial cell-derived cytokines thymic stromal lymphopoietin (TSLP), IL-33, and IL-25 are central regulators of type 2 immunity, which drives a broad array of allergic responses. Often characterized as "alarmins" that are released by the barrier epithelium in response to external insults, these epithelial cell-derived cytokines were initially thought to act only early in allergic inflammation. Indeed, TSLP can condition dendritic cells to initiate type 2 responses, and IL-33 may influence susceptibility to asthma through its role in establishing the immune environment in the perinatal lungs.

Nocturnal asthma is affected by genetic interactions between RORA and NPSR1.

Pediatr Pulmonol 2019 Mar 29. Epub 2019 Mar 29.

Department of Pediatric Pneumology and Allergy, University Children's Hospital Regensburg (KUNO), Regensburg, Germany.

Background: Neuropeptide S Receptor 1 ( NPSR1) and Retinoid Acid Receptor-Related Orphan Receptor Alpha (RORA ) interact biologically, are both known candidate genes for asthma, and are involved in controlling circadian rhythm. Thus, we assessed (1) whether interactions between RORA and NPSR1 specifically affect the nocturnal asthma phenotype and (2) how this may differ from other asthma phenotypes.

Methods: Interaction effects between 24 single-nucleotide polymorphisms (SNPs) in RORA and 35 SNPs in NPSR1 on asthma and nocturnal asthma symptoms were determined in 1432 subjects (763 asthmatics [192 with nocturnal asthma symptoms]; 669 controls) from the Multicenter Asthma Genetic in Childhood/International Study of Asthma and Allergies in Childhood studies.

Bronchoalveolar Lavage Cytology Characteristics and Seasonal Changes in a Herd of Pastured Teaching Horses.

Front Vet Sci 2019 14;6:74. Epub 2019 Mar 14.

Department of Clinical Sciences, College of Veterinary Medicine, North Carolina State University, Raleigh, NC, United States.

Equine asthma syndrome (EAS) is a common problem that affects horses of any age. Severe EAS is reported to affect 10-20% of adult horses in the northern hemisphere, while mild/moderate EAS is reported to affect 60-100% of adult horses, depending on the population and geographic region. For both severe and mild/moderate EAS, the presence of lower airway inflammation is attributed to airborne "triggers" such as dust, mold, and bacterial components that horses encounter in hay and stable-environments; and treatment recommendations for horses with EAS often include full-time pasture turnout.

Female and male mouse lung group 2 innate lymphoid cells differ in gene expression profiles and cytokine production.

PLoS One 2019 26;14(3):e0214286. Epub 2019 Mar 26.

Terry Fox Laboratory, British Columbia Cancer, Vancouver, British Columbia, Canada.

Epidemiological studies have shown sex differences in prevalence of non-allergic asthma. Recent reports demonstrated negative effects of androgen signaling on group 2 innate lymphoid cells (ILC2s), explaining a potential mechanism behind sex bias in asthma prevalence. To further understand sex-related differences in ILC2 functions and ILC2 intrinsic or lung environmental mechanisms behind it, we have investigated the effects of sex and age on lung ILC2 function, the amounts of ILC2-activating cytokines in the lung and gene expression profiles of male and female ILC2s.

Leukocyte Telomere Length Reflects Prenatal Stress Exposure, But Does Not Predict Atopic Dermatitis Development at 1 Year.

Allergy Asthma Immunol Res 2019 May;11(3):357-366

Department of Pediatrics, Seoul National University College of Medicine, Seoul, Korea.

Purpose: Prenatal maternal stress affects offspring's atopic dermatitis (AD) development, which is thought to be mediated by the oxidative stress. We aimed to evaluate the difference in leukocyte telomere length (LTL), a marker for exposure to oxidative stress, according to the prenatal stress exposure and the later AD development.

Methods: From a birth cohort (the COhort for Childhood Origin of Asthma and allergic diseases) that had displayed a good epidemiologic association between the exposure to prenatal stress and AD development in the offspring, we selected 68 pairs of samples from 4 subject groups based on the level of prenatal maternal stress and later AD development.

[Environmental risk factors for asthma developement].

Presse Med 2019 Mar 23;48(3 Pt 1):262-273. Epub 2019 Mar 23.

Inserm U1168, VIMA (aging and chronic diseases, epidemiological and public health approaches), Villejuif, France; UVSQ, UMR-S 1168, université Versailles, Saint-Quentin-en-Yvelines, France.

The prevalence of asthma has increased rapidly since the early 1970s, and only changes in exposure to environmental factors; which go together with changes in lifestyle, are likely to explain such a rapid increase. Exposure to allergens is a risk factor for allergic sensitization, and allergic sensitization is a risk factor for allergic asthma. However, apart from indoor mold exposure as a risk factor for childhood asthma, there is insufficient evidence to conclude that the associations between allergen exposure and asthma development are causal.

The Role of Environmental Controls in Managing Asthma in Lower-Income Urban Communities.

Clin Rev Allergy Immunol 2019 Mar 22. Epub 2019 Mar 22.

Department of Environmental Health Sciences, Mailman School of Public Health, Columbia University, 722 West 168th Street, 11th floor, New York, NY, 10032, USA.

Children living in lower-income urban communities are at much greater risk of developing asthma, going to the emergency department for an asthma attack and being hospitalized for asthma than children living in upper- and middle-income communities. For many asthmatic children living in urban communities, especially those with greater morbidity, the allergic pathway is important in the etiology of the disease. The stages of developing allergic disease can be divided into the onset of allergic sensitization, development of allergic disease and subsequent exacerbations, and it is useful to consider the relevance of interventions at each of these stages.

Allergic Comorbidity in Eosinophilic Esophagitis: Mechanistic Relevance and Clinical Implications.

Clin Rev Allergy Immunol 2019 Mar 22. Epub 2019 Mar 22.

Division of Allergy and Immunology, Department of Pediatrics, Children's Hospital of Philadelphia, Perelman School of Medicine at the University of Pennsylvania, Abramson Research Building, 3615 Civic Center Blvd, Philadelphia, PA, 19104, USA.

Allergic eosinophilic esophagitis (EoE) is a chronic, allergen-mediated inflammatory disease of the esophagus, and the most common cause of prolonged dysphagia in children and young adults in the developed world. While initially undistinguished from gastroesophageal reflux disease-associated esophageal eosinophilia, EoE is now recognized as a clinically distinct entity that shares fundamental inflammatory features of other allergic conditions and is similarly increasing in incidence and prevalence. The clinical and epidemiologic associations between EoE and other allergic manifestations are well established. Read More

IL33: Roles in Allergic Inflammation and Therapeutic Perspectives.

Front Immunol 2019 4;10:364. Epub 2019 Mar 4.

State Key Laboratory of Research on Bioactivities and Clinical Applications of Medicinal Plants, Institute of Chinese Medicine, The Chinese University of Hong Kong, Shatin, Hong Kong.

Interleukin (IL)-33 belongs to IL-1 cytokine family which is constitutively produced from the structural and lining cells including fibroblasts, endothelial cells, and epithelial cells of skin, gastrointestinal tract, and lungs that are exposed to the environment. Different from most cytokines that are actively secreted from cells, nuclear cytokine IL-33 is passively released during cell necrosis or when tissues are damaged, suggesting that it may function as an alarmin that alerts the immune system after endothelial or epithelial cell damage during infection, physical stress, or trauma. IL-33 plays important roles in type-2 innate immunity via activation of allergic inflammation-related eosinophils, basophils, mast cells, macrophages, and group 2 innate lymphoid cells (ILC2s) through its receptor ST2.

Household dampness-related exposures in relation to childhood asthma and rhinitis in China: A multicentre observational study.

Environ Int 2019 May 14;126:735-746. Epub 2019 Mar 14.

School of Environmental Science and Engineering, Tianjin University, Tianjin, China.

During 2010-2012, we conducted an observational study on household environment and health outcomes among 40,010 preschool children from seven cities of China. Here we examined associations of six dampness-related indicators (visible mold spots, visible damp stains, damp clothing and/or bedding, water damage, condensation on windowpane, moldy odor) in the current residence and three dampness-related indicators (visible mold spots, condensation on windowpane, moldy odor) in the early residence with childhood asthma and rhinitis. In the multi-level logistic regression analyses, visible mold spots and visible damp stains in the current residence were significantly associated with the increased odds of doctor-diagnosed asthma and allergic rhinitis during lifetime-ever (adjusted odd ratios (AORs) range: 1.

Epigenome-wide association study reveals methylation pathways associated with childhood allergic sensitization.

Epigenetics 2019 Mar 15:1-22. Epub 2019 Mar 15.

a Channing Division of Network Medicine, Department of Medicine , Brigham and Women's Hospital, Harvard Medical School , Boston , MA , USA.

Epigenetic mechanisms integrate both genetic variability and environmental exposures. However, comprehensive epigenome-wide analysis has not been performed across major childhood allergic phenotypes. We examined the association of epigenome-wide DNA methylation in mid-childhood peripheral blood (Illumina HumanMethyl450K) with mid-childhood atopic sensitization, environmental/inhalant and food allergen sensitization in 739 children in two birth cohorts (Project Viva-Boston, and the Generation R Study-Rotterdam).

PEBBLES study protocol: a randomised controlled trial to prevent atopic dermatitis, food allergy and sensitisation in infants with a family history of allergic disease using a skin barrier improvement strategy.

BMJ Open 2019 Mar 13;9(3):e024594. Epub 2019 Mar 13.

Allergy and Lung Health Unit, Melbourne School of Population and Global Health, University of Melbourne, Melbourne, Victoria, Australia.

Introduction: The skin is an important barrier against environmental allergens, but infants have relatively impaired skin barrier function. There is evidence that impaired skin barrier function increases the risk of allergic sensitisation, atopic dermatitis (AD) and food allergy. We hypothesise that regular prophylactic use of emollients, particularly those that are designed to improve skin barrier structure and function, will help prevent these conditions. Read More

Using high-resolution residential greenspace measures in an urban environment to assess risks of allergy outcomes in children.

Sci Total Environ 2019 Jun 2;668:760-767. Epub 2019 Mar 2.

Division of Biostatistics & Epidemiology, Cincinnati Children's Hospital Medical Center, 3333 Burnet Ave., Cincinnati, OH 45229, USA.

Despite reported health benefits of urban greenspace (gs), the epidemiological evidence is less clear for allergic disease. To address a limitation of previous research, we examined the associations of medium- and high-resolution residential gs measures and tree and/or grass canopies with allergic outcomes for children enrolled in the longitudinal cincinnati childhood allergy and air pollution study (ccaaps). We estimated residential gs based on 400 m radial buffers around participant addresses (n = 478) using the normalized differential vegetation index (ndvi) and land cover-derived urban greenspace (ugs) (tree and grass coverage, combined and separate) at 30 m and 1.
