PubMedID: 30777551Objectives: In patients with advanced-stage chronic kidney disease, renal insufficiency, arterial stiffness, and vascular calcification are strong predictors of cardiovascular risk. Signal peptide-CUB-EGF-like protein-1 (SCUBE1) levels increase during platelet activation and acute ischemic events. Here, we evaluated associations between SCUBE1 levels and electrocardiographic/echocardiographic findings, epicardial adipose tissue thickness, and carotid intima-media thickness in patients with chronic kidney disease. Materials and Methods: Our study included 21 renal transplant recipients, 20 peritoneal dialysis patients, 20 hemodialysis patients, 20 predialysis patients with glomerular filtration rate < 30 mL/min, and 16 healthy volunteers. Results: We found no differences in SCUBE1 levels between patient groups and healthy volunteers, regardless of history of diabetes mellitus, myocardial infarction, cerebrovascular events, and hypertension. SCUBE1 levels correlated with C-reactive protein in renal transplant recipients; magnesium in peritoneal dialysis patients; erythrocyte sedimentation rate in predialysis patients; and parathyroid hormone, platelet count, calcium-phosphate product, and calcium in hemodialysis patients. No associations were shown between SCUBE1 levels and electrocardiographic/echocardiographic findings. Elevated C-reactive protein in predialysis patients was associated with cardiac valvular pathologies. In hemodialysis patients, SCUBE1 levels increased after hemodialysis (P = .007). Levels were higher in healthy individuals with normal echocardiography and pre-dialysis patients with left ventricular diastolic dysfunction. Positive correlations were found between carotid intima-media thickness and SCUBE1 levels in dialysis patients (P < .05), but no study groups showed correlations regarding epicardial adipose tissue thickness. Conclusions: Hemodialysis may contribute to cardiovascular events because of increased SCUBE1 levels after hemodialysis; however, no association was shown between SCUBE1 and electrocardiography/ echocardiography findings. We found no correlations between epicardial adipose tissue thickness and SCUBE1 levels, and levels were significantly higher in healthy patients and in predialysis patients without left ventricular diastolic dysfunction. However, correlations were shown between SCUBE1 levels and carotid intima-media thickness and secondary hyperparathyroidism markers, indicating associations with atherosclerosis and bone mineral disease in dialysis patients. © Başkent University 2019 Printed in Turkey.
