Introduction: Electronic health records (EHRs) are increasingly used to estimate the prevalence of childhood asthma. The relation of these estimates to those obtained from parent-reported wheezing suggestive of asthma is unclear. We hypothesised that parent-reported wheezing would be more prevalent than general practitioner (GP)-recorded asthma diagnoses in preschool-aged children. Methods: 1529 of 1840 (83%) Millennium Cohort Study children registered with GPs in the Welsh Secure Anonymised Information Linkage databank were linked...

BACKGROUND: Recent findings have supposed that the underlying association between the increased prevalence of both asthma and obesity may be insulin resistance (IR). METHODS: Insulin and glucose serum levels were analyzed to calculate the homeostatic model assessment of insulin resistance (HOMA-IR) for IR in 98 pre-pubertal children. Lung function and allergy status evaluation were performed. The study population was divided into four groups: (1) obese asthmatic children (ObA); (2) normal-weight asthmatic children (NwA); (3) normal-weight non-asthmatic children (Nw) and (4) obese non-asthmatic children (Ob)...

BACKGROUND: Children with multimorbid asthma and rhinitis show IgE polysensitization to several allergen sources. This association remain poorly studied in adolescents and adults using defined allergen molecules. We investigated IgE sensitization patterns towards a broad panel of aeroallergen components in adults and adolescents with a focus on individuals with asthma and rhinitis multimorbidity. METHODS: IgE reactivity to 64 microarrayed aeroallergen molecules was determined with the MeDALL-chip in samples from the French EGEA study (n=840, age=40...

BACKGROUND: Different wheezing and asthmatic phenotypes turned out to indicate differences in etiology, risk factors and health care. We examined influential factors and urban-rural differences for different phenotypes. METHODS: Parents of 4732 children filled out a questionnaire concerning children's health and environmental factors administered within the Health Monitoring Units (GME) in a cross-sectional study in Bavaria, Germany (2014/2015). To classify respiratory symptoms, five phenotype groups were built: episodic, unremitting and frequent wheeze, ISAAC (International Study of Asthma and Allergies in Children) - asthma and physician-diagnosed asthma (neither of the groups are mutually exclusive)...

Ongoing advancements in neonatal care since the late 1980's have led to increased numbers of premature infants surviving well beyond the neonatal period. As a result of increased survival, many individuals born preterm manifest chronic respiratory symptoms throughout infancy, childhood and adult life. The archetypical respiratory disease of prematurity, bronchopulmonary dysplasia (BPD), is the second most common chronic pediatric respiratory disease after asthma. However, there are several commonly held misconceptions...

Despite increased understanding of how viral infection is involved in asthma exacerbations, it is less clear which viruses are involved and to what extent they contribute to asthma exacerbations. Here, we sought to determine the prevalence of different respiratory viruses during asthma exacerbations. Systematic computerized searches of the literature up to June 2017 without language limitation were performed. The primary focus was on the prevalence of respiratory viruses, including AdV (adenovirus), BoV (bocavirus), CoV (coronavirus), CMV (cytomegalovirus), EnV (enterovirus), HSV (herpes simplex virus), IfV (influenza virus), MpV (metapneumovirus), PiV (parainfluenzavirus), RV (rhinovirus) and RSV (respiratory syncytial virus) during asthma exacerbations...

BACKGROUND: A rising trend in Sri Lanka for asthma and wheezing illness is observed with higher morbidity in younger children and a paucity of related research. 'Under-served settlements' (USS) of Colombo Municipal Council (CMC) have poor living environments conducive to childhood wheezing. The objective was to describe the prevalence and associated factors of wheezing illnesses of three to five year old children living in low-income settlements in CMC. METHODS: A cross-sectional study was conducted on 460 three to five year old children and their caregivers using cluster sampling among residents of two randomly selected USSs of CMC...

Human parainfluenza viruses (family Paramyxoviridae), human metapneumovirus, and respiratory syncytial virus (family Pneumoviridae) infect most infants and children within the first few years of life and are the etiologic agents for many serious acute respiratory illnesses. These virus infections are also associated with long-term diseases that impact quality of life, including asthma. Despite over a half-century of vaccine research, development, and clinical trials, no vaccine has been licensed to date for the paramyxoviruses or pneumoviruses for the youngest infants...

Asthma and anxiety are highly co-morbid, and their interaction leads to exacerbations for both conditions. This study explored the interplay between these two conditions from the perspective of children and adolescents. The objective was to identify potential mechanisms of interaction between asthma and anxiety, and to derive improvements for prevention and treatment. Eleven semi-structured interviews of young people (aged 11-15), who met criteria for both asthma and anxiety, were analysed using interpretative phenomenological analysis...

The composition of the human gut microbiome matures within the first years of life. It has been hypothesized that microbial compositions in this period can cause immune dysregulations and potentially cause asthma. Here we show, by associating gut microbial composition from 16S rRNA gene amplicon sequencing during the first year of life with subsequent risk of asthma in 690 participants, that 1-year-old children with an immature microbial composition have an increased risk of asthma at age 5 years. This association is only apparent among children born to asthmatic mothers, suggesting that lacking microbial stimulation during the first year of life can trigger their inherited asthma risk...

Asthma is a major cause of morbidity and mortality despite advances in outpatient treatment. Sometimes, children fail to respond to standard treatment and can potentially require mechanical ventilation. We describe a case of a 26-month-old girl with a severe asthma exacerbation successfully managed by ketamine administration via nebulization route that permitted to avoid mechanical ventilation. Nebulized ketamine might be a reasonable option to avoid mechanical ventilation in children who fail to respond to standard treatment of severe asthma exacerbation...

Current studies of gene × air pollution interaction typically seek to identify unknown heritability of common complex illnesses arising from variability in the host's susceptibility to environmental pollutants of interest. Accordingly, a single component generalized linear models are often used to model the risk posed by an environmental exposure variable of interest in relation to a priori determined DNA variants. However, reducing the phenotypic heterogeneity may further optimize such approach, primarily represented by the modeled DNA variants...

BACKGROUND: Frequent wheezing in original Asthma Predictive Index (API) was defined by parental report of recurrent wheezing within 1 year during the first 3 years of life. The nature of frequent wheezing in children, particularly aged over 3 years has not been studied. We aimed to assess the frequency and interval of wheezing to define frequent wheezing in ascertaining asthma for children using medical records. METHODS: Among children who participated in a previous study (n=427), all wheezing episodes documented in medical records were collected for children who had ≥2wheezing episodes PLUS met one major criteria or two minor criteria of API...

Background: DNA methylation of CpG sites on genetic loci has been linked to increased risk of asthma in children exposed to elevated ambient air pollutants (AAPs). Further identification of specific CpG sites and the pollutants that are associated with methylation of these CpG sites in immune cells could impact our understanding of asthma pathophysiology. In this study, we sought to identify some CpG sites in specific genes that could be associated with asthma regulation (Foxp3 and IL10) and to identify the different AAPs for which exposure prior to the blood draw is linked to methylation levels at these sites...
