Evaluation of Endothelial Dysfunction in Geriatric Non-dialysis Chronic Kidney Disease Patients

Brief summary template The goal of this clinical trial is to assess endothelial dysfunction in geriatric non-dialysis CKD patients. The main questions it aims to answer are: • In geriatric non-dialysis CKD patients, the study aimed to demonstrate the relationship between soluble vascular endothelial cadherin and fibroblast growth factor-23 levels, which are indicators of endothelial dysfunction-and therefore a possible cardiovascular risk factor-using measurement methods such as ultrasonographic carotid intima-media thickness, flow-mediated dilation, and nailfold capillaroscopy. Participants will have measurement of; * ultrasonographic carotid intima-media thickness, * flow-mediated dilation, * nailfold capillaroscopy * venous blood sampling * Visit the clinic once,

In this single-center study, we aimed to evaluate endothelial dysfunction, the leading cause of mortality in geriatric CKD patients. We kept patient exclusion criteria strict and considered it more rational to conduct this study in a patient group requiring proactive intervention by excluding patients with 'known' cardiovascular disease. For this purpose, we used some non-invasive parameters known in the literature (ultrasonographic measurement of carotid intima-media thickness, nailfold capillaroscopy, flow-mediated dilation). We also planned to measure serum sVE Cadherin levels, which have not been clearly evaluated in geriatric CKD patients before, as well as serum FGF23 levels. We also planned to evaluate the relationship and correlation of these different parameters with other standard biochemical and anthropometric measurements. Patient recruitment for the study took place between May 12, 2023, and September 11, 2023. We followed up for mortality for approximately 2.3 years.
