About this trial

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.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

HbA1c ≥6.0% for untreated high-risk group

BMI ≥ 85th %ile for high-risk group

Normal HbA1c ≤5.6% for control group

Type 1 diabetes (T1D) Antibody negative

Disqualifiers

Trial population

The investigators propose to address the specific aims of this study in an accelerated longitudinal project with 40 adolescents with normal HbA1c (≤5.6%) and 60 with overweight/obesity and/or newly diagnosed T2D (BMI≥85%ile) and elevated HbA1c (≥6.0%) or on anti-diabetic medications ranging from TS 1-4 (Ages 8-14 yr). They will be studied annually for 2 years.
