BACKGROUND: Epidemiological studies have suggested that elevated levels of air pollution contribute to an increased incidence or severity of asthma. Although late-onset adult asthma seems to be more attributable to environmental risk factors, limited data is available on the impact of early-life exposure to size-fractionated ambient particulate matter (PM) on asthma in adults. We aimed to determine the effect on the development and exacerbation of asthma in the adult after the mice were exposed as juveniles to three size-fractionated ambient particulates collected from Beijing...

Chronic obstructive pulmonary disease (COPD) is often misdiagnosed and inappropriately treated in many patients. COPD is a distinct disease from adult-onset asthma; however, some patients with COPD may present with several forms of airway disease described as asthma-COPD overlap (ACO). Bronchodilators and inhaled corticosteroids (ICS) both have a place in standard maintenance treatment of COPD and asthma; however, recommendations for use differ widely. In patients with COPD, long-acting bronchodilators are effective initial monotherapy treatment, while ICS monotherapy is recommended as initial treatment in patients with asthma...

Inverse association between allergic conditions and glioma risk has been consistently reported in epidemiological studies with little attention paid to potential environmental confounders; the association with meningioma risk is less consistent. We examined the association between allergy history and risk of glioma and meningioma in adults using data from the CERENAT (CEREbral tumors: a NATional study) multicenter case-control study carried out in 4 areas in France in 2004-2010. Participants' histories of doctor-diagnosed allergic asthma, eczema, rhinitis/hay fever and other allergic conditions were collected at onset through a detailed questionnaire delivered in a face-to-face interview...

A1AT deficiency- a genetically inherited autosomal codominant disease with more than 120 identified alleles- was first identified by Laurell and Eriksson in 1963. The most common hereditary disorder in adults, A1AT causes an increased risk of developing pulmonary emphysema and liver disease. In A1AT patients, lung disease generally presents at a younger age than "usual" chronic obstructive pulmonary disease (COPD) and it may be misdiagnosed as asthma. Because A1AT deficiency patients can show the same clinical features as non-deficient COPD (including increased evidence of bronchiectasis, frequent exacerbations, impaired health status and a degree of reversibility of airflow obstruction), the World Health Organization recommend to test every patient with a diagnosis of COPD or adult-onset asthma for A1AT deficiency...

Tobacco smoke, active or passive exposure was the major cause of preventable morbidity and mortality in the world during twentieth century and will continue to be the same in the twenty-first century also if the current trends continue. Both active and passive smoking are having significance in relation to child health. Exposure starts antenatally from placenta to the fetus and later phases through passive exposure to experimental and regular smoking and ultimately addiction and habitual smoking. Evidences are in favour of causal relationship with intrauterine growth restriction, sudden infant death syndrome, decreased pulmonary function, increased risk for respiratory tract infection, otitis media, wheeze, asthma, neurobehavioral disorders, cleft palate and triggering pathogenesis of fetal and childhood onset of adult diseases, especially pulmonary and cardio vascular diseases...

Because the pathophysiology of asthma has diverse characteristics, to manage the disease effectively, it is important for clinicians to distinguish among the clinical phenotypes. Among them, adult-onset asthma, that is, late-onset asthma (LOA), is increasing because of the aging of the population. The phenotype of LOA is largely divided into two types according to the presence or absence of eosinophilic inflammation, T-helper (Th)2- and non-Th2-associated LOA. Especially in Th2 LOA related to rhinosinusitis, as pulmonary function at onset is poor and asthma exacerbations occur frequently, it is important to detect this phenotype in the early phase by using a biomarker of Th2-type inflammation such as fractional exhaled nitric oxide (FE NO )...

Little is known about the prognosis of adults with new-onset asthma. Cross-sectional studies suggest that these patients may exhibit accelerated decline in forced expiratory volume in 1 s (FEV1 ). However, risk factors for accelerated decline in lung function have not yet been identified.We aimed to identify these risk factors in a prospective 5-year follow-up study in 200 adults with newly diagnosed asthma. In the current study, clinical, functional and inflammatory parameters were assessed annually for 5 years...

BACKGROUND: We explore the concept of "untimely diagnosis," where the onset of a long-term condition occurs at a life stage which does not conform to traditional expectations, focusing on two conditions (asthma and arthritis) typically associated with a particular life stage (childhood and older adulthood, respectively). Previous literature has focused on the meaning of chronic illness in terms of life history, and the biographical lens has been used in various ways to make sense of the experience...

BACKGROUND: Chronic sinusitis is a commonly diagnosed condition in adults who frequently present with late-stage disease and irreversible changes to the sinus mucosa. Understanding the natural history of chronic sinusitis is critical in developing therapies designed to prevent or slow the progression of disease. OBJECTIVE: to determine early-life risk factors for adult sinusitis in a longitudinal cohort study (Tucson Children's Respiratory Study). METHODS: Physician-diagnosed sinusitis was reported at age 6...

Background and objectives: Genome-wide association studies identified single-nucleotide polymorphisms (SNPs) at the 17q21 locus conferring increased risk for childhood-onset asthma. Little is known about how these SNPs impact adult asthma patients. We sought to examine an adult population for associations between rs7216389 (17q21-associated SNP) and features of asthma including fractional exhaled nitric oxide (FeNO), eosinophil counts, and age of asthma onset. Methods: Subjects were genotyped at SNP rs7216389...

Asthma is an oxidative stress related disease, but associations with asthma outcomes are poorly studied in adults. We aimed to study the associations between several biomarkers related to oxidative stress and various asthma outcomes.Cross-sectional analyses were conducted in 1388 adults (mean age 43 years, 44% with asthma) from the Epidemiological Study of the Genetics and Environment of Asthma (EGEA2). Three blood antioxidant enzyme activities (biomarkers of response to oxidative stress) and exhaled breath condensate 8-isoprostanes and plasma fluorescent oxidation products (FlOPs) levels (two biomarkers of damage) were measured...

Bordetella pertussis isolation by culture has low detection sensitivity for diagnosing pertussis; the diagnosis is confirmed by measuring serum anti-pertussis toxin (anti-PT) or anti-filamentous hemagglutinin antibody titers, and by genetic testing (polymerase chain reaction/loop-mediated isothermal amplification). Isolation of B. pertussis in adults is difficult, resulting in a delayed diagnosis, as a delayed cough may present ≥3 months after onset. Differentiation from bronchial asthma is also important...

BACKGROUND: The prognosis for patients beyond 1 year after reduction of their inhaled corticosteroid (ICS) dose remains unknown. Predictive factors that can be evaluated before the initiation of asthma treatment or at ICS dose reduction are unknown. METHODS: We prospectively studied 223 patients in 6 hospitals in the National Hospital Organization of Japan during the 36 months after 50% reduction of their daily ICS dose. All patients recorded their morning and evening peak expiratory flows (PEFs) in their diaries...

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...
