Breastfeeding does not protect children against asthma and allergies

(Uppsala University) The effect of breastfeeding on the risk of developing asthma and allergy has been debated for a long time. In a recent study, Uppsala University researchers show that breastfeeding might in fact increase the risk of developing hay fever and eczema, while not having any clear effect on the risk of asthma. The results have been published in the Journal of Allergy and Clinical Immunology.

Conclusions Asthma and allergic rhinitis were twice as prevalent in urban settings. Asthma was associated with greater impairment and worse lung function outcomes. We identified a high prevalence of allergic disorders in Uganda, which can be expected to increase due to urbanization and resultant exposures throughout early development.

Allergic childhood diseases exhibit a high degree of comorbidity. The concept of the atopic march is based on observations that eczema tends to precede later development of asthma and allergic rhinitis (AR). The causal nature of this progression, however, remains a topic of debate. It has been suggested that the atopic march is initiated through eczema in early childhood and that eczema promotes the development of food and airway allergies by driving systemic sensitization through a compromised epithelial barrier.

The objective of this study was to characterize the burden of atopic dermatitis in Japanese adult patients relative to the general population. Japanese adults (≥18 years) with a self‐reported diagnosis of atopic dermatitis and adult controls without atopic dermatitis/eczema/dermatitis were identified from the 2013 Japan National Health and Wellness Survey. Atopic dermatitis patients were propensity‐score matched with non‐atopic dermatitis controls (1:2 ratio) on demographic variables. Patient‐reported outcome data on comorbidities, mood and sleep disorders, health‐related quality of life, work productivity and...

ConclusionsExposure to prenatal maternal psychosocial stress was associated with increased risk, albeit modestly, of asthma and allergy in the offspring. The pronounced risk during the third trimester may represent cumulative stress exposure throughout pregnancy rather than trimester‐specific effect. Our findings may represent a causal effect or a result of inherent biases in studies, particularly residual confounding.This article is protected by copyright. All rights reserved.

This study was aimed at identification of risk factors for work-related skin diseases among vocational students of agriculture. MATERIAL AND METHODS: The study involved 440 students (245 males, 195 females aged 17-21 years) in 11 vocational schools which were at least 100 km from each other. The protocol included a physician-managed questionnaire and medical examination, skin prick tests, patch tests, total IgE and Phadiatop. Logistic regression model was used for the identification of relevant risk factors. RESULTS: Work-related dermatoses were diagnosed in 29 study participants (6.6%, 95%CI: 4.3-8.9%): eczema i...

Industrialized countries have registered epidemic rates on allergic diseases, such as hay fever, asthma, eczema, and food allergies. The Hygiene Hypothesis was born from work made by Dr. David Strachan, who observed that younger siblings were less susceptible to eczema and asthma, and proposed that this was a result of increased transmission of infectious agents via unhygienic practices within a household. This initial hypothesis was then reframed as the old friends/microbiota hypothesis, implicating non-pathogenic commensal microorganisms as the source of immunomodulatory signals necessary to prevent immune-mediated chronic disorders.
