- Abstract
Perirenal fat is adjacent to kidneys and active in metabolism and adipokine secretion. We aimed to investigate whether perirenal fat is an independent predictor for chronic kidney disease (CKD) and compared it with total, subcutaneous, or visceral fat in patients with diabetes. Perirenal fat thickness (PRFT) was measured by computed tomography, and total body fat (TBF), subcutaneous adipose tissue (SAT), and visceral adipose tissue (VAT) were assessed by DEXA. In cross-sectional analysis, patients with higher PRFT had a lower estimated glomerular filtration rate (eGFR). Multiple linear regression analysis showed a negative correlation between PRFT and eGFR after confounders adjustment. No association between eGFR and TBF, SAT, or VAT was observed. Longitudinally, 190 patients with type 2 diabetes mellitus (T2DM) without CKD at baseline were followed for 2 years. A total of 29 participants developed CKD. After VAT-based multivariate adjustment, each SD (per-SD) increment in baseline PRFT was associated with a higher incidence of CKD (hazard ratio 1.67, 95% CI 1.04-2.68), while TBF, SAT, and VAT were not. Furthermore, PRFT predicted CKD, with a C-statistic (95% CI) of 0.668 (0.562, 0.774), which was higher than that of TPF [0.535 (0.433, 0.637)], SAT [0.526 (0.434, 0.618)], and VAT [0.602 (0.506, 0.698)]. In conclusion, with perirenal fat there was a higher predictive value for CKD than with total, subcutaneous, or visceral fat in T2DM.
