Aim: We aim to assess association of DNA methylation (DNAm) at birth with total immunoglobulin E (IgE) trajectories from birth to late adolescence and whether such association is ethnicity-specific.
Methods: We examined the association of total IgE trajectories from birth to late adolescence with DNAm at birth in two independent birth cohorts, the Isle of wight birth cohort (IOWBC) in UK ( = 796; White) and the maternal and infant cohort study (MICS) in Taiwan ( = 60; Asian). Biological pathways and methylation quantitative trait loci (methQTL) for associated Cytosine-phosphate-Guanine sites were studied.
Results: Two total IgE trajectories, high vs. low, were inferred from each of the two cohorts. Associations of DNAm at 103 CpGs with IgE trajectories in IOWBC and at 476 CpGs in MICS were identified. Between the two cohorts, of the identified CpGs, one was in common, methQTL site cg16711274 (mapped to gene MINAR1), and 17 pathways were common with at least four linked to airway diseases.
Conclusion: The findings suggest at-birth epigenetics may explain ethnicity differences in total IgE trajectories later in life.

Background: Meniere disease (MD), an inner ear disorder influenced by genetic and environmental factors, potentially leads to chronic inflammation. This study evaluates whether inflammation in MD patients is driven by allergy or autoinflammation.
Methods: 2-year longitudinal study.

Background: Hen's egg exposure through impaired skin barrier is considered a major mechanism of sensitization to eggs. However, the impact of filaggrin (FLG) gene loss-of-function mutations on the natural history of egg sensitization lacks consensus among studies.
Objective: To evaluate the association between the natural course of egg sensitization and FLG mutations.

Background: Allergic sensitization and low lung function in early childhood are risk factors for subsequent wheezing and asthma. However, it is unclear how allergic sensitization affects lung function over time.
Objective: We sought to test whether allergy influences lung function and whether these factors synergistically increase the risk of continued wheezing in childhood.
