Objective: Anthropometric parameters may play a role in modulating the risk of kidney dysfunction. The aim of this study was to evaluate whether anthropometric indices and the metabolic syndrome are associated with alterations of the renal resistive index (RI) in normoalbuminuric type 2 diabetic (T2DM) patients. Methods: A sample of 99 consecutively recruited patients with T2DM (76 male and 23 female) was examined. The RI was assessed by duplex Doppler sonography. Results: In univariate analysis, a significant association between the RI values and age (r = 0.507, p < 0.0001), gender (being higher in women, p = 0.002), systolic blood pressure (r = 0.285, p = 0.011), smoking habit (being lower in current smokers, p = 0.047), estimated glomerular filtration rate (r = - 0.435, p < 0.0001), and intima- media thickness of the carotid arteries (r = 0.271, p = 0.020) was observed. As far as anthropometric parameters are concerned, a strong correlation between waist circumference (WC; r = 0.401, p < 0.0001), BMI (r = 0.337, p = 0.003) and RI values was found but only WC maintained a significant correlation after adjusting for several confounders (p = 0.001). Conclusions: In normoalbuminuric T2DM patients, the intrarenal hemodynamic abnormalities seem primarily associated with WC. Copyright (c) 2007 S. Karger AG, Basel.
