Objective: To assess whether increased genetic risk for type 2 diabetes (T2D) is associated with the development of hyperglycemia after glucocorticoid treatment.

Research Design and Methods: We performed a retrospective analysis of individuals with no diagnosis of diabetes who received a glucocorticoid dose equivalent to 10 mg of prednisone or more. We analyzed the association between hyperglycemia and a T2D global extended polygenic score, which was constructed through a meta-analysis of two published genome-wide association studies.

Results: Out of 546 individuals who received glucocorticoids, 210 developed hyperglycemia and 336 did not. The polygenic score was significantly associated with glucocorticoid-induced hyperglycemia (p = 0.038, OR = 1.4 per standard deviation of the polygenic score).

Conclusions: Individuals with increased genetic risk for T2D have a higher risk of glucocorticoid-induced hyperglycemia. This finding offers a mechanism for risk stratification as part of a precision approach to medical treatment.
