Abstract
This study aimed to compare the renal resistive index (RI) as an early marker of
renal damage between normoalbuminuric children with type 1 diabetes mellitus (T1D) and normal
age-matched controls. A total of 76 children with T1D (aged 10-18 years) and 76 healthy age-matched
controls were enrolled. Anthropometric parameters, blood pressure, glycated hemoglobin
(HbA1c), serum creatinine (sCr), estimated glomerular fi ltration rate (eGFR), serum uric acid (SUA),
urine albumin/creatinine ratio (ACR), and degree of pubertal development were determined in all
participants. RI was measured using Doppler ultrasound in both groups. The T1D group had lower sCr
and SUA values and higher ACR and mean RI values than the control group. Using the expectation-maximization
method, 2 clusters of T1D patients were identified. Cluster 2 with higher RI values,
eGFR and HDL cholesterol was more prone to albuminuria and could carry worse prognosis. In
conclusion, renal RI is increased in the hyperfiltration phase of diabetic nephropathy in children
with T1D. Renal RI could be helpful as a marker for diagnosing diabetic nephropathy in the early
preclinical course of the disease in normoalbuminuric children with T1D.
