چکیده: (1017 مشاهده)
Background: Endothelial dysfunction has a significant role in the pathogenesis of cardiovascular events in patients with kidney dysfunction. The present study aimed to compare the level of endothelial dysfunction in patients with chronic kidney disease (CKD) and acute kidney injury (AKI) by brachial artery flow-mediated dilation (FMD) technique. Also, we sought to find whether this non-invasive technique may assist in accurately distinguishing the acute or chronic nature of kidney failure in patients presenting with uremia for the first time.
Methods: Demographic and medical characteristics, and laboratory and renal ultrasonography data of the patients with AKI and CKD were collected and compared with a control group. Brachial artery FMD was measured using a Toshiba aplio 300 device with a 7.5 MHz linear probe.
Results: In a total of 175 patients with a mean (SD) age of 55.96(15.54) years, FMD% was significantly lower in the CKD and AKI patients compared to the control group (Mean±SD: 16.28%±10.52%), 16.28 %±4.35%, and 24.24±5.71, respectively, p<0.001). Among the different causes of AKI, contrast-induced nephropathy (10.78%±1.75%), volume depletion (14.87%±1.22%), and post-renal AKI (15.96%±1.54%) had the lowest levels of FMD. Also, a significant correlation between FMD and eGFR (r=0.26, P<0.001), serum Hb (r=0.18, P=0.013), Na (r=0.19, P=0.011), BUN (r=-0.21, P=0.005) and Cr (r=- 0.13, P=0.084) was reported.
Conclusion: Compared to the control group, CKD and AKI patients showed greater levels of endothelial dysfunction as evidenced by lower brachial artery FMD. However, the FMD technique did not appear to be a practical method in differentiating CKD and AKI in patients presenting with uremia for the first time.
