What is it about?

Numerous environmental factors are known to trigger type 1 diabetes. This study aimed to determine whether there is an association between influenza and new-onset type 1 diabetes. Although only patients with type 1 diabetes were included, in the adjusted analysis, individuals had a 1·3-fold (95% confidence interval: 1·15–1·46) higher risk of developing type 1 diabetes within 180 days after an influenza diagnosis than at other times. The sensitivity analyses confirmed the robustness of this finding.

Why is it important?

The risk of new-onset type 1 diabetes increased after influenza was diagnosed in this Japanese population-based cohort. using administrative claims database. These results, which must be confirmed in other populations, suggest that influenza virus infection may be a causal factor in new-onset type 1 diabetes. The molecular mechanisms underlying the potential etiological relationship between influenza and type 1 diabetes requires should be evaluated further.
