Association between childhood atopic disease and parental atopic disease in a population with high consanguinity

Area of Science:

• Pediatrics
• Allergology
• Genetics

Background:

• Asthma, allergic rhinitis, and eczema are common childhood conditions.
• Family history is a known risk factor for allergic diseases.
• Understanding genetic predispositions is crucial for early diagnosis and management.

Purpose of the Study:

• To investigate the association between parental allergic conditions and the prevalence of asthma, allergic rhinitis, and eczema in Qatari schoolchildren.
• To explore the familial aggregation of allergic diseases within a Qatari population.

Main Methods:

• A cross-sectional study involving 3500 Qatari schoolchildren aged 6-14 years.
• Data collected via questionnaires on parental and sibling clinical history of asthma, allergic rhinitis, and eczema.
• Analysis of the correlation between parental allergic conditions and allergic diseases in children.

Main Results:

• 21.6% of asthmatic children had mothers with asthma; 18.2% had fathers with asthma.
• 41.8% of asthmatic children had at least one parent with allergic rhinitis; 10.0% had both parents with allergic rhinitis.
• Significant association found between parental respiratory allergies/eczema and allergic conditions in their asthmatic children.

Conclusions:

• Parental history of asthma and allergic rhinitis is strongly associated with allergic diseases in Qatari schoolchildren.
• The findings suggest a significant genetic component in the development of asthma, allergic rhinitis, and eczema.
• This emphasizes the importance of family history in assessing allergy risk in pediatric populations.
