Early diabetic kidney disease (DKD) occurs in 50-70% of youth with type 2 diabetes (T2D) and confers high lifetime risk of dialysis and premature death. Youth-onset T2D typically manifests during or shortly after puberty in adolescents with obesity. Epidemiological data implicate puberty as an accelerator of kidney disease in youth with obesity and diabetes and the investigators posit that the link between puberty and T2D-onset may explain the high burden of DKD in youth-onset T2D. A better understanding of the impact of puberty on kidney health is needed to promote preservation of native kidney function, especially in youth with T2D.
Puberty is a complex process of physiological changes, including neuroreproductive and growth hormone activation and rapid organ growth, that may predispose organs to injury. The kidneys may be especially susceptible because they are highly metabolically active and second only to the heart with respect to oxygen consumption per tissue mass. During puberty, the kidneys almost double in size, likely increasing the kidneys' already high energy expenditure. In parallel, puberty is associated with physiologic insulin resistance (IR), which is accentuated in obesity. Our central hypothesis is that o…
