Does maternal diet during pregnancy influence clinical and laboratory characteristics of infantile-onset atopic...

Area of Science:

• Allergy and Immunology
• Dermatology
• Nutritional Science

Background:

• Rising incidence of Atopic Dermatitis (AD) suggests prenatal environmental influences.
• Investigating maternal diet during pregnancy as a potential factor in offspring AD.
• Focus on dietary habits and their correlation with AD development and severity.

Purpose of the Study:

• To explore associations between maternal dietary intake during pregnancy and AD in children.
• To examine the relationship between specific maternal food consumption and clinical/laboratory AD markers in offspring.
• To identify potential dietary interventions for preventing or managing infantile AD.

Main Methods:

• Cross-sectional study involving 100 mother-child pairs with infantile-onset AD.
• Assessment of maternal dietary habits during pregnancy (dairy, eggs, meat, fish, fruits, vegetables).
• Evaluation of clinical variables (onset age, severity, multimorbidity) and laboratory markers (serum IgE, eosinophils) in children.

Main Results:

• Lower maternal egg intake during pregnancy correlated with higher serum total IgE and peripheral eosinophilia in children with AD.
• A trend suggested fish consumption may be linked to reduced atopic multimorbidity.
• No significant associations found between other maternal dietary factors and clinical AD variables.

Conclusions:

• Maternal egg consumption during pregnancy may impact atopy-related laboratory markers in offspring.
• Preliminary findings highlight a potential role for maternal diet in modulating infant immune responses.
• Further prospective cohort studies are necessary to confirm and elucidate these dietary associations in AD.
