Abstract
Objectives
To study the urinary neutrophil gelatinase-associated lipocalin (NGAL) and beta-2-microglobulin (β2M) levels as markers of tubular damage in children with type 1 diabetes (T1DM).
Methods
Forty T1DM children and 40 age-matched controls were enrolled. Subjects with coexisting kidney disorder, intake of oral glucose lowering drugs and syndromic diabetes mellitus were excluded. Fasting plasma glucose, glycated hemoglobin (HbA1c), kidney function, urinary albumin-creatinine ratio (UACR), NGAL and β2M were measured and compared in cases and controls.
Results
The median (IQR) age of cases and controls was 10.6 (8, 14.2) and 10.7 (8.4, 13.7) years, respectively. Cases had disease duration of 4 (3, 6.8) years and HbA1c 10.9 (9, 13.1) %. Microalbuminuria was seen in 14 (35 %). Median (IQR) levels of UACR were higher in cases than controls [19.38 (10.27, 35.26) and 6.49 (3.10, 11.65) µg/mg; p<0.001], similarly NGAL/creatinine [352.21 (191.49, 572.45) and 190.54 (125.91, 322.83) ng/mg; p=0.006], unlike β2M/creatinine [1.7 (0.43, 6.02) and 2.12 (1.05, 4.47) µg/mg; p=0.637]. Children with higher HbA1c (≥10 %) had higher urinary ACR and tubular biomarkers than HbA1c<10 % (p>0.05). Urinary ACR showed positive correlation with NGAL/creatinine (r=0.38, p=0.019) and β2M/creatinine (r=0.42, p=0.009).
Conclusions
Urinary biomarkers NGAL and β2M were elevated in the presence of normal urinary microalbumin levels suggestive of early tubular damage in T1DM.
