BACKGROUND: Asthma is a chronic respiratory disease without a cure, though there exists spontaneous remission. Genome wide association(GWA) studies have pinpointed genes associated with asthma development, but did not investigate asthma remission. OBJECTIVES: We performed a GWA study to develop insights in asthma remission. METHODS: Clinical remission (ClinR) was defined by absence of asthma treatment and wheezing in the last year and asthma attacks in the last 3 years, and complete remission (ComR) similarly but additionally with normal lung function and absence of bronchial hyperresponsiveness (BHR)...

A small but significant subset of asthmatic children show a lack of response to standard management, resulting in further intensification of therapy to optimise symptom control and may remain symptomatic despite maximal therapy. Severe asthma results in increased risk of adverse outcomes whilst contributing significantly to the economic burden on the nation's health resources. The ERS / ATS guidelines were published in 2014 and form the basis of identifying, evaluating and managing severe asthmatic children...

RATIONALE: Recurrent wheeze and asthma are thought to result from alterations in early life immune development following RSV infection, however, prior studies of the nasal immune-response to infection have assessed only individual cytokines, which doesn't capture the whole spectrum of response to infection. OBJECTIVE: To identify nasal immune phenotypes in response to RSV infection and their association with recurrent wheeze. METHODS: A birth cohort of term healthy infants born June-December were recruited and followed to capture the first infant RSV infection...

OBJECTIVE: Different phenotypes of wheezing have been described to date but not in early life. We aim to describe wheezing phenotypes between the ages of two months and one year, and assess risk factors associated with these wheezing phenotypes in a large birth cohort. METHODS: We studied 18,041 infants from the ELFE (French Longitudinal Study of Children) birth cohort. Parents reported wheezing and respiratory symptoms at two and 12 months, and answered a complete questionnaire (exposure during pregnancy, parental allergy)...

BACKGROUND: Exploring patterns of childhood wheeze may help to clarify the etiology and prognosis of respiratory diseases. The purpose of this study was to classify phenotypes of wheezing in children up to 9 years of age in Japan and to evaluate the individual and environmental risk factors for these phenotypes. METHODS: Wheeze was evaluated at approximately 1-year intervals based on the mothers' recollection of their child's wheezing or whistling in the chest during the preceding 12 months...

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...

Here we reported a case of bronchial adenoid cystic carcinoma from Peking University Third Hospital. A 40-year-old female presented with dry cough for 1 year and nocturnal paroxysmal attacks of wheezing for 4 months. She was a non-smoker, and did not have past histories of asthma or allergy. On physical examination, no stridor, wheezing and cyanosis were present and the general appearance was good. The results of the laboratory analysis, including blood eosinophils count, immunoglobulin E level and chest X-ray were normal...

Systematic reviews suggest that breastfeeding is associated with a lower risk of asthma, although marked heterogeneity exists. Using UK Millennium Cohort Study data (n = 10,126 children born 2000-2001), we examined the association between breastfeeding duration and wheezing in the past year, first at each age-group separately (age 9 months, 3, 5, 7 and 11 years) and then as a longitudinal wheezing phenotype: 'early transient' (wheezing any time up to age 5 but not thereafter); 'late onset' (any time from age 7 but not beforehand); 'persistent' (any time up to age 5 and any time from age 7)...

Genetic defects of NKX2-1 are classically associated with hypothyroidism, benign chorea and neonatal respiratory distress. The purpose of this study was to identify the genetic pathogenesis of the "NKX2-1 triad" in a 10 year-old female presenting additional features barely described in the disorder. In the neonatal period, she presented with generalized hypotonia and respiratory distress, with later episodes of frequent wheezing. At 3 month-age developmental dysplasia of the hip was diagnosed and at 10 months, primary hypothyroidism was detected and treated...

Preschool wheeze is a common but poorly understood cause of respiratory morbidity that is both distinct from and overlaps with infantile bronchiolitis and school age asthma. Attempts at classification by epidemiology, pathophysiology, therapeutic response and clinical phenotype are imperfect and yet fundamental to both treatment choice and research design. The four main therapeutic classes for preschool wheeze, namely beta2 agonists, anticholinergics, corticosteroids and leukotriene modifiers are employed with variable and often scanty evidence base, with evidence for a genetic influence on response variations...

Lower prenatal exposure to n-3 PUFA relative to n-6 PUFA has been hypothesised to influence allergy development, but evidence remains largely inconsistent. In the Dutch Maastricht Essential Fatty Acid Birth (MEFAB) (n 293) and Greek RHEA Mother-Child (n 213) cohorts, we investigated whether cord blood phospholipid PUFA concentrations are associated with symptoms of wheeze, asthma, rhinitis and eczema at the age of 6-7 years. Information on allergy-related phenotypes was collected using validated questionnaires...

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: 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)...

BACKGROUND: Asthma is common among schoolchildren and may influence quality of life and school attendance. However, it is unclear if asthma affects school performance. The aim of this study was to examine whether different phenotypes of asthma affect school performance during adolescence. METHODS: The study population consisted of 1715 adolescents from a population-based birth cohort, followed up to age 16 with questionnaires and clinical examinations. Asthma was defined as at least 4 wheeze episodes or at least 1 wheeze episode in combination with inhaled steroids in the last 12 months...

BACKGROUND: Rhinovirus-induced wheezing in young children has been associated with increased asthma risk at school age. Recently, the transmembrane protein cadherin-related family member 3 (CDHR3) was identified as the RV-C receptor and the genetic variant rs6967330 (p.Cys529Tyr) was reported to be associated with enhanced RV-C binding and increased replication in vitro. The aim of this study was to examine rs6967330 genotypes and mRNA expression of CDHR3 in relation to presence of rhinovirus and clinical symptoms in children with acute wheezing and compare to a group of age-matched healthy children...

A growing body of literature has investigated optimizing asthma management by identifying phenotypes and biomarkers to guide the treatment. In particular, management of asthma in preschool children remains challenging due to different phenotype presentation in early life. The focus of this review is to summarize the recent data on personalized medicine in management of preschool children with wheezing.
