Atopic dermatitis (AD) is a complex disease with multiple causes and complex mechanistic pathways according to age of onset, severity of the illness, ethnic modifiers, response to therapy, and triggers. A group of difficult-to-manage patients characterized by early-onset AD and severe lifelong disease associated with allergic asthma and/or food allergy, has been identified. In this paper, we focus on these severe phenotypes, analyzing their links with other atopic comorbidities, and taking into account the results from recent cohort studies and meta-analyses...

The global burden of lung disease is substantial, accounting for an estimated 7.5 million deaths per year, approximately 14% of annual deaths worldwide. The prime illnesses include, in descending order, chronic obstructive pulmonary disease, lung cancer, tuberculosis, acute respiratory infections, asthma, and interstitial lung fibrosis. Key risk factors include smoking, both indoor and outdoor air pollution, and occupational exposures. Although the distribution of both the diseases and the risk factors varies greatly by age, geography, and setting, the greatest burden falls on populations living in low- and middle-income countries...

Asthma is a chronic inflammatory disease affecting the airway, and it is characterized by a wheezing breathing sound, variable airflow obstruction and the presence of inflammatory cells in the submucosa of the bronchi. Viral infection, pollutants and sensitivity to aeroallergens damage the epithelium from childhood, which causes asthma. The pathogenesis of asthma includes pathways of innate stimulation by environmental microbes and irritant pathogens. Damaged epithelial cells produce thymic stromal lymphopoietin (TSLP) and stimulate myeloid dendritic cell maturation through the thymic stromal lymphopoietin receptor (TSLPR) heterocomplex...

Kampo medicines prescribed by specialized medical practitioners and Japanese physicians have gradually reemerged in Japan as alternatives to Western medications. Kampo formulations are composed of several plant extracts and, as such, the broad variety of phytochemicals they contain likely act synergistically to provide their beneficial effects. Kampo medicines have traditionally been prescribed for a number of health conditions, including chronic hepatitis, bronchial asthma, anemia, etc. The aim of this article is to review the beneficial effects of Kampos with respect to oral health...

Exposure to particulate matter (PM) leads to kinds of cardiopulmonary diseases, such as asthma, COPD, arrhythmias, lung cancer, etc., which are related to PM-induced inflammation. We have found that PM2.5 (aerodynamics diameter <2.5 µm) exposure induces inflammatory response both in vivo and in vitro. Since the toxicity of PM is tightly associated with its size and components, PM1 (aerodynamics diameter <1.0 µm) is supposed to be more toxic than PM2.5 . However, the mechanism of PM1 -induced inflammation is not clear...

The prevalence of vitamin D insufficiency, usually assessed by the analysis of circulating 25-hydroxyvitamin D (25[OH])D), is very high in the aging German population. An important factor that reduces endogenous vitamin D synthesis in older persons is physical inactivity or care-dependency that limits the time spent outside. Additionally, it has been suggested that the age-dependent decline in the glomerular filtration rate is associated with a reduced production of bioactive calcitriol. As this phenomenon is not detectable by the assessment of 25(OH)D, it is necessary to analyze the level of parathyroid hormone as a marker of calcitriol function...

Casticin (3', 5-dihydroxy-3, 4', 6, 7-tetramethoxyflavone), one of the main components from Vitex rotundifolia L., was reported to possess several pharmacological properties, including anti-inflammatory, hepatoprotective, anticancer, anti-asthma activities. However, the effects of casticin on airway smooth muscle cells (ASMCs) proliferation and migration have not been explored. This study aimed to evaluate the effects of casticin on the proliferation and migration of ASMCs, and study the possible molecular mechanism...

BACKGROUND: A major goal of asthma therapy is to achieve disease control, with maintenance of lung function, reduced need for rescue medication, and prevention of exacerbation. Despite current standard of care, up to 70% of patients with asthma remain poorly controlled. Analysis of serum and sputum biomarkers could offer insights into parameters associated with poor asthma control. OBJECTIVE: To identify signatures as determinants of asthma disease control, we performed proteomics using Olink proximity extension analysis...

RATIONALE: Childhood asthma has shown variable associations with children's physical activity. Neighborhood walkability captures community features that promote walking and is protective against some chronic conditions, such as obesity and diabetes. OBJECTIVES: We evaluated associations between home neighborhood walkability and incident and ongoing childhood asthma. METHODS: This population-based cohort study used prospectively-collected administrative healthcare data for the province of Ontario housed at the Institute for Clinical Evaluative Sciences...

Food allergy is one of the most important health issues worldwide. In Taiwan, current literature suggests shrimps and crabs are the most common causes of food allergy, and are frequently associated with acute allergic reactions such as urticaria, atopic dermatitis, and asthma. However, knowledge regarding the shrimp allergens remains limited. Thus, there is an urgent need to establish comprehensive information for elucidating underlying triggers for food allergy. In this study, whiteleg shrimp (Litopenaeus vannamei) was used to evaluate the IgE-binding properties of various shrimp proteins to 7 allergic patients' sera by western blot...

Primary care clinicians have a central role in managing influenza/influenza-like illness (ILI) during influenza pandemics. This study identifies risk factors for influenza-related complications in children presenting with influenza/ILI in primary care. We conducted a cohort study using routinely collected linked data from the Clinical Practice Research Datalink on children aged 17 years and younger who presented with influenza/ILI during the 2009/10 pandemic. We calculated odds ratios (ORs) for potential risk factors in relation to influenza-related complications, complications requiring intervention, pneumonia, all-cause hospitalisation and hospitalisation due to influenza-related complications within 30 days of presentation...

Background: The reemergence of enterovirus D68 (EV-D68) infections in the United States was reported from August-October 2014 (691 cases). In Mexico, an outbreak at the National Institute of Respiratory Diseases was reported (24 cases). The results of epidemiological surveillance of Enterovirus sp. (EV) and other respiratory viruses in a national pediatric tertiary care level hospital are presented. Methods: Following the alert issued by the reemergence of EV-D68 in 2014, epidemiological surveillance -which only detected respiratory viruses by PCR in patients with influenza-like illness using nasopharyngeal swabs- expanded to include children with asthma exacerbation or acute respiratory distress...

BACKGROUND: Outdoor pollen grain and fungal spore concentrations have been associated with severe asthma exacerbations at the population level. The specific impact of each taxon and the concomitant effect of air pollution on these symptoms have, however, still to be better characterized. This study aimed to investigate the short-term associations between ambient concentrations of various aeroallergens and hospitalizations related to asthma in the Brussels-Capital Region (Belgium), an area recording especially high rates of admissions...

We have a unique opportunity to significantly reduce the worldwide burden of asthma in children and impact respiratory outcomes in adults. However, this will require a paradigm shift that is directed at altering the natural history of asthma, reducing asthma exacerbations and preventing long-term adverse outcomes of childhood asthma. Attention should continue to be directed toward minimizing risk as well as impairment with a goal to achieve optimal control. Based on several NIH studies conducted over the last 10 years we now have the tools necessary to accomplish this goal...

Peter Le Souëf
Over the past year, studies into virus-induced wheeze in children have shifted towards investigations that examine the mechanisms by which respiratory viruses cause wheeze and an increase in studies examining the effects of novel interventions to reduce wheezing exacerbations. Studies on rhinovirus species (RV)-C infection have found that this is associated with a decrease in expression of CDHR3, the cellular receptor specific for this virus, and a decrease in interferon-β expression, both of which are likely to favour RV-C infection...

Desensitization for pneumallergens is used in daily practice for the treatment of allergic rhinitis and allergic asthma. However, specific immunotherapy has long been debated in the medical literature as a treatment for allergic asthma until the latest international recommendations for the management of asthma (GINA) reveal specific immunotherapy as a treatment in sensitized patients, poorly controlled by inhaled corticosteroids (FEV 1 > 70%). In this article you will find a current overview of the medical literature on the usefulness of specific desensitization to reduce asthma symptoms and symptomatic treatments, prevent the onset of asthma in patients with allergic rhinitis as well as prevent new sensitizations...
