Design: The environmental Determinants of Diabetes in the Young study prospectively followed children carrying the hla risk haplotypes DQ2 and/or DQ8 and constructed a nested case–control design. From this design, 83 cDa case–control pairs were identified. Median age of cDa was 31 months. stool samples collected monthly up to the age of 2 years were analysed for virome composition by illumina next-generation sequencing followed by comprehensive computational virus profiling.
Results: The cumulative number of stool enteroviral exposures between 1 and 2 years of age was associated with an increased risk for cDa. in addition, there was a significant interaction between cumulative stool enteroviral exposures and gluten consumption. The risk conferred by stool enteroviruses was increased in cases reporting higher gluten intake.
Conclusions: Frequent exposure to enterovirus between 1 and 2 years of age was associated with increased risk of cDa. The increased risk conferred by the interaction between enteroviruses and higher gluten intake indicate a cumulative effect of these factors in the development of cDa.
