Plasma miRNAs and treatment failure among participants in the Treatment Options for Diabetes in Youth (TODAY) study
Objective
To identify plasma miRNAs related to treatment failure in youth with type 2 diabetes (T2D).
Research Design & Methods
We examined whether a panel of miRNAs could predict treatment failure in training/test datasets among participants in the Treatment Options for Diabetes in Youth (TODAY) Study (n=209). We also examined whether individual miRNAs were associated with treatment failure.
Results
Participants were 14.5 years old and 62% female. A panel of miRNAs did not predict treatment failure. However, for each doubling, miR-4306 was associated with a 12% decrease and miR-483-3p (p=0.040) was marginally associated with a 12% increase in failure (p=0.080) independent of sex, race/ethnicity, BMI, Tanner stage, HbA1c, maternal diabetes, oral disposition index, and treatment arm. The addition of both miRNAs improved model fit (log likelihood without miRNAs -360.3 vs. with -363.5, p=0.040).
Conclusions
miR-483-3p and miR-4306 may be associated with treatment failure in youth with T2D.
