Comparing positive (n = 17) and negative (n = 17) NGAL in T1MD group (E and/or S fractions) (Table 2) we found that positive NGAL subjects were older (15.60 ± 3.10 vs 12.00 ± 5.50 years, p = 0.03), had a longer diabetes evolution (6.60 ± 5.40 vs 4.34 ± 3.10 years, p = 0.03), higher serum creatinine levels (0.64 ± 0.10 vs 0.52 ± 0.12 mg/dl, p = 0.01), and higher median of HbA1c one year before enrollment (8.80 ± 3.00 vs 7.40 ± 1.30%, p = 0.045) than negative NGAL participants. The gene discussed is LCN2; the disease is diabetes mellitus.
