Coeliac disease: what can we learn from prospective studies about disease risk?

Area of Science:

• Pediatrics
• Immunology
• Genetics

Background:

• Coeliac disease (CD) is an immune-mediated disorder triggered by gluten ingestion in genetically susceptible individuals.
• Understanding CD pathogenesis requires investigating complex interactions between genetic predisposition and environmental exposures.
• Paediatric prospective studies offer unique longitudinal data for dissecting disease etiology.

Purpose of the Study:

• To review current knowledge on genetic and environmental risk factors for coeliac disease from paediatric prospective studies.
• To highlight the potential of omics technologies in elucidating gene-environment interactions in CD.
• To outline future directions for paediatric research in CD risk prediction and biomarker discovery.

Main Methods:

• Review of international paediatric prospective cohort studies.
• Analysis of findings from genetic association studies and environmental exposure research.
• Integration of recent advances in multiomics (genomics, transcriptomics, proteomics, metabolomics).

Main Results:

• Paediatric prospective studies have identified key genetic and environmental factors influencing coeliac disease risk.
• Omics studies are revealing intricate interactions between genetic susceptibility and environmental triggers.
• Longitudinal data are crucial for understanding disease development and progression.

Conclusions:

• Paediatric prospective studies are essential for advancing our understanding of coeliac disease.
• Future research integrating multiomics data will enable more accurate risk prediction models.
• These studies hold promise for developing novel biomarkers and improving therapeutic strategies for coeliac disease.
