OBJECTIVE: Type 1 diabetes mellitus (DM1) and obesity represent two chronic pediatric diseases characterized by increased risk for renal impairment and cardiovascular disease. The potential usefulness of neutrophil gelatinase-associated lipocalin (NGAL) and matrix metalloproteinase-9 (MMP-9), two novel biomarkers, for predicting early kidney injury or increased cardiovascular risk in children and adolescents with DM1 or obesity, was investigated in this cross-sectional study.

PATIENTS AND METHODS: Serum samples were obtained from children and adolescents aged 12.7 ± 3.8 years old with DM1 (n = 38) or obesity (n = 34) and normal renal function, as well as from healthy controls (n = 24). NGAL and MMP-9 concentrations were measured using commercially available sandwich ELISA kits (NGAL: DY1757-05, MMP-9: DMP900; R&D systems, Minneapolis, MN, USA).

RESULTS: NGAL serum values were found significantly higher in patients with obesity but not in those with DM1. A positive correlation was found in patients with DM1 with diabetes duration, and in the total population with body mass index (BMI) z-score. Also, serum MMP-9 levels were significantly increased in patients with DM1 and in patients with obesity compared to controls.

CONCLUSIONS: Circulating NGAL and MMP-9 levels may prove useful as surrogate biomarkers to creatinine, glomerular filtration rate (GFR), and albumin excretion rate for early detection of kidney injury and cardiovascular complications in children and adolescents with DM1 or obesity.
