BACKGROUND: Many studies have attempted to clarify the factors associated with serum periostin levels in asthmatic patients. However, these results were based on studies of subjects mainly characterized by high eosinophil counts, which may present as an obstacle for clarification in the identification of other factors associated with serum periostin levels. The aim of this study was to determine the factors associated with serum periostin levels in healthy subjects. We also assessed some factors in asthmatic subjects to confirm their extrapolation for management of asthma...

Unhealthy lifestyle factors such as poor diet quality, sedentary lifestyle, and obesity are associated with negative health consequences in asthma including poor asthma control, impaired quality of life, and greater health care utilization. Lifestyle modification is the cornerstone of behavioral treatments and has been effective in chronic diseases such as atherothrombotic vascular disease and diabetes. There is a critical need for lifestyle interventions in asthma care that address obesity and its intimately linked risk behaviors in terms of poor diet and physical inactivity...

BACKGROUND: Traffic-related air pollution (TRAP) exposure has been linked to type 2 diabetes and metabolic dysfunction in humans. Animal studies suggest that air pollutants may alter the composition of the gut microbiota, which may negatively impact metabolic health through changes in the composition and/or function of the gut microbiome. OBJECTIVES: The primary aim of this study was to determine whether elevated TRAP exposure was correlated with gut bacterial taxa in overweight and obese adolescents from the Meta-AIR (Metabolic and Asthma Incidence Research) study...

Obesity is a high risk factor for diseases such as cardiovascular, metabolic syndrome and asthma. Obese-asthma is another emerging phenotype in asthma which is typically refractive to steroid treatment due to its non-classical features such as non-eosinophilic cellular inflammation. The overall increased morbidity, mortality and economical burden in asthma is mainly due to steroid resistant asthma. In the present study, we used high fat diet induced obese mice which when sensitized with house dust mite (HDM) showed steroid resistant features...

It is uncertain whether phenotypes of asthma and chronic obstructive pulmonary disease (COPD) vary between populations with different genetic and environmental characteristics. Here, our objective was to compare the phenotypes of airways disease in two separate populations.This was a cross-sectional observational study in adult populations from New Zealand and China. Participants aged 40-75 years who reported wheeze and breathlessness in the last 12 months were randomly selected from the general population and underwent detailed characterisation...

BACKGROUND: Obesity is a risk factor for the development of asthma. In patients with obesity the diagnosis of asthma is often based on symptoms, but without objective measurements. Nevertheless, obesity-associated asthma is recognized as a distinct asthma phenotype. Therefore, this study explores lung function and symptoms in asthma patients with and without obesity. METHODS: The Netherlands Epidemiology of Obesity (NEO) study is a population-based cohort study with 6671 participants (aged 45-65 years) of whom 472 had asthma...

PURPOSE OF REVIEW: Emerging research on the pediatric microbiome implicates the importance of the microbiome on the development of the immune system, nervous system, and growth. Changes to the microbiome during infancy are associated with the development of chronic illnesses such as asthma and inflammatory bowel disease. Additionally, the microbiome provides protection against certain pathogens, affects vaccine responses, and alters drug metabolism. This review highlights what is known about the microbiome, the establishment of a healthy microbiome and the significance that changes to the microbiome composition have on growth and health of children and adolescents...

BACKGROUND: The weight loss induced by bariatric surgery (BS) improves asthma clinical control evaluated usually after a short time. The long-term effects of weight loss attained by BS on asthma control and health related-quality of life (HRQoL) in patients affected by asthma and obesity are not known. OBJECTIVE: To investigate the five-year effect of weight reduction induced by BS on asthma control, quality of life and pulmonary functional parameters in severely obese intermittent or mild-to-moderate asthmatic patients...

Background: Obesity is a medical condition that is known for increased body mass index (BMI). It is also associated with chronic low level inflammation. Obesity disrupts the immune-metabolic homeostasis by changing the secretion of adipocytes. This affects the end-organs, and gives rise to several diseases including type 2 diabetes, asthma, non-alcoholic fatty liver diseases and cancers. These diseases are known as co-morbid diseases. Several studies have explored the underlying molecular mechanisms of developing obesity associated comorbid diseases...

Background: The prevalence of obesity has dramatically increased in children in the last few decades and is associated with chronic inflammatory diseases. Fat tissue produces IL-6 and TNF-α, which are stimuli for TH17 cell differentiation. These cells are characterized by expression of the transcription factor receptor-related orphan receptor C (RORC) and by IL-17A production. In murine models, obesity has been linked with elevated TH17 cell frequencies. The aim of this study was to explore whether being overweight was associated with an elevated frequency of circulating TH17 cells or elevated messenger RNA (mRNA)-levels of IL-17A and RORC in children without chronic inflammatory diseases...

Dysbiosis of the gut microbiota has been associated with increasing numbers of diseases, including obesity, diabetes, inflammatory bowel disease, asthma, allergy, cancer and even neurologic or behavioral disorders. The other side of the coin is that a healthy microbiota leads to a healthy human development, to a mature and well trained immune system and to an efficient metabolic machinery. What we have learned in adults is in the end the result of a good start, a programmed, healthy development of the microbiota that must occur in the early years of life, probably even starting during the fetal stage...

Macrophages are essential innate immune cells that also regulate local metabolism. Endogenous or exogenous stimuli may polarize macrophages towards phenotypes that serve distinct innate immunological metabolic functions. IFNγ or lipopolysaccharide (LPS) polarizes macrophages towards the M1, or "classically activated" phenotype that participates in defense against intracellular pathogens. IL-4, IL-13, or chitin polarizes macrophages towards the M2, or "alternatively activated" phenotype, which defends against multicellular nematodes and fungi...

The care of patients with difficult-to-control asthma ('difficult asthma') is challenging and costly. Despite high-intensity asthma treatment, these patients experience poor asthma control and face the greatest risk for asthma morbidity and mortality. Poor asthma control is often driven by severe asthma biology, which has appropriately been the focus of intense research and phenotype-driven therapies. However, it is increasing apparent that extra-pulmonary comorbidities also contribute substantially to poor asthma control and a heightened disease burden...

PURPOSE OF REVIEW: Obesity is a worldwide epidemic with a prevalence that has tripled in the last two decades. Worldwide, more than 1.5 billion adults are overweight and more than 500 million obese. Obesity has been suggested to be a risk factor for the development of more difficult-to-control asthma. Although the mechanisms underlying the asthma-obesity relationship are not fully understood, several possible explanations have been put forward. These will be reviewed in this manuscript as well as the implications for the treatment of overweight and obese asthma patients...

BACKGROUND: Asthma in the elderly population (60 years of age and older) is frequently underdiagnosed, as well as atopy. Atopy, although more prevalent in younger patients, can be a major cause of asthma in the elderly. Chronic obstructive pulmonary disease (COPD) and cardiovascular disease are common differential diagnoses, especially in elderly smokers. OBJECTIVE: The objective of this study was to assess atopy and comorbidities in elderly patients with asthma...

The gastrointestinal microbiome is a diverse consortium of bacteria, archaea, fungi, protozoa, and viruses that inhabit the gut of all mammals. Studies in humans and other mammals have implicated the microbiome in a range of physiologic processes that are vital to host health including energy homeostasis, metabolism, gut epithelial health, immunologic activity, and neurobehavioral development. The microbial genome confers metabolic capabilities exceeding those of the host organism alone, making the gut microbiome an active participant in host physiology...
