Occurrence of pollen season at the end of the first trimester predicts clinical atopic diseases in the offspring: A Finnish population-based study.

Occurrence of pollen season at the end of the first trimester predicts clinical atopic diseases in the offspring: A Finnish population-based study. Int J Hyg Environ Health. 2020 Jan 28;225:113452 Authors: Pyrhönen K, Kulmala P Abstract OBJECTIVE: To evaluate the association between potential exposure to different pollen concentrations at the 11th fetal week and subsequent clinical atopic diseases. STUDY DESIGN AND SETTING: Parents of 1- to 4-year-old children (N = 3035) returned a questionnaire regarding physician-diagnosed atopic diseases. The children were born between 2001 and 2005 in the province of South Karelia, Finland. Results of allergy tests were collected from patient records in the area. RESULTS: The prevalence of atopic diseases with sensitisation was higher in children whose 11th fetal week occurred during pollen rather than non-pollen season: atopic eczema 6.3% vs. 4.3% (adjusted odds ratio, aOR 1.58, 95% CI 1.10─2.28), food allergy 5.7% vs. 3.9% (1.63; 1.12─2.38), respiratory allergy or asthma 3.7% vs. 2.2% (2.03; 1.24─3.33) and any atopic diseases 7.4% vs. 5.5% (1.48; 1.07─2.05), respectively. Respectively, the prevalence was higher in the children exposed to high rather than low tree pollen concentrations (>1000 vs.

ConclusionEczema phenotypes were differentially associated with risks of respiratory and allergic conditions in school-aged children. Children with early transient and persistent eczema might benefit from more intense follow-up for early identification and treatment of asthma and allergies.

In the early 1990s, doctors began describing a new condition affecting the esophagus of patients who were predisposed to allergies including food allergy, asthma, and eczema, and who were having trouble swallowing. Today, we call this condition eosinophilic esophagitis (EoE). What is EoE? EoE is an allergic inflammation of the esophagus that causes a range of symptoms. Adolescents and adults most often experience it as difficulty swallowing, sometimes feeling like food moves too slowly through the esophagus and into the stomach. In some cases, food actually gets stuck (and may require urgent removal). Children and some adu...

Allergic diseases such as atopic dermatitis (AD), food allergy (FA), asthma and allergic rhinitis (AR) are common; according to a national birth cohort study in Japan, almost half of pregnant women reported a history of allergic disease.1 Given that genetic factors, including family history, are predictors of allergic diseases in offspring, we expect the birth of many infants who carry a high risk of developing allergies. Among allergy prevention strategies, the effectiveness of primary prevention of eczema in high-risk infants by the topical application of emollient during the neonatal period has been demonstrated in two ...

Background: Allergic respiratory disorders often co-exist, but little is known about their specific patterns, exposure profiles or COPD risk.Objectives: To identify latent patterns of allergic respiratory disorders and their exposure profiles and COPD risk.Methods: Latent patterns of current asthma, hayfever, eczema, food allergy with their ages at onset, chronic cough, chronic sputum and allergic sensitivities were identified, using latent class analysis (LCA), among 3608 participants from the Tasmanian Longitudinal Health Study (mean age: 53 years), and cross-sectionally associated with exposures and COPD risk.Results: F...

In this study we observed an association between allergic disease and communication skills development as assessed by the Ages and Stages Questionnaire (ASQ) communication score, as a proxy for ASD, among children who participated in the Vitamin D Antenatal Asthma Reduction Trial (VDAART). In particular, we observed significant associations between both a diagnosis of eczema at age 3 years (OR=1.87; confidence interval [CI]: 0.97-3.47; p=0.054) and a diagnosis of food allergy at age 6 years (OR=3.61; 95% CI: 1.18-9.85; p=0.015) with ASQ communication score. Plasma metabolomics analyses suggest that dysregulated tryptophan ...

Conclusions: We found strong effects of parental history of allergy, eczema or asthma on the presence of physician-diagnosed inhalant allergy in children at age 10  years. Eczema ever at age 10 years was a strong risk factor for the development of physician-diagnosed inhalant and food allergy.What is Known:• The prevalence of allergic diseases in children has markedly increased.• Early-life influences are critically important in the development of allergic diseases.What is New:• Maternal and paternal history of allergy, eczema or asthma is associated with increased risks of physician-diagnosed inha...
