BACKGROUND AND AIM DNA methylation (DNAm) is considered a plausible pathway through which genetic and environmental factors may influence the development of allergies. However, causality has to be determined as it unknown whether DNAm rather cause or consequence allergic sensitization. Here, we investigated direction observed associations between well-known determinants allergy, DNAm, aeroaller...

Methods In this cross sectional study, 103 consecutive patients with seasonal allergic rhinitis were enrolled. Sensitization to common aeroallergen confirmed by skin prick test 3 millimeter more than negative control. Clinical symptoms, personal and familial history of atopy and demographic data were listed. According to food allergy history 63 of 103 patients had positive Open SingleBlind Oral...

Of the four modes of treating human allergic disease, avoidance or separation of the allergic patient from the allergen source is most effective and least expensive. The clinical immunology laboratory has established efficient and inexpensive "reservoir" dust sampling and processing procedures to obtain a surface dust specimen that reflects the allergen burden of the environment. Following extr...

OBJECTIVE Irritant gases and aerosols contaminating the air of indoor swimming pools can affect the lung epithelium and increase asthma risk in children. We evaluated the impact of infant swimming practice on allergic status and respiratory health later in childhood. METHODS Clara cell protein, surfactant-associated protein D, and total and aeroallergen-specific immunoglobulin E were measured...

BACKGROUND Positive greenness effects on health are increasingly reported, although studies on allergic outcomes remain limited and conflicting. We examined whether residential greenness is associated with childhood doctor diagnosed allergic rhinitis, eyes and nose symptoms and aeroallergen sensitisation using two combined birth cohorts (GINIplus and LISAplus) followed from birth to 10 years in...

Protectins are newly identified natural chemical mediators that counter leukocyte activation to promote resolution of inflammation. In this study, we provide the first evidence for protectin D1 (PD1, 10R,17S-dihydroxy-docosa-4Z,7Z,11E,13E,15Z,19Z-hexaenoic acid) formation from docosahexaenoic acid in human asthma in vivo and PD1 counterregulatory actions in allergic airway inflammation. PD1 and...

A multicentre, prospective cohort study of childhood asthma was established in three European countries; the purpose of the project is the examination of factors which modify the relationship between allergen exposure in infant life and subsequent atopy and asthma. Dust samples were collected from the homes of 643 infants in a single town in the UK (the first cohort) and assayed for house dust ...

BACKGROUND Wheezing is a highly frequent symptom in infants and children. Its major causes are respiratory infections and bronchial asthma. In this context, allergen sensitization plays an important role, and it can be detected by a skin prick test, a safe and effective technique that can be easily performed on any age-group. To assess the prevalence of aeroallergen sensitization in a pediatric...
