Abstract

Endothelial progenitor cells (EPCs) CD34 are bone marrow-derived cells that decrease in chronic kidney disease (CKD) patients especially when they reach end-stage renal disease and may be a risk marker of cardiovascular (CV) diseases. The aim of our study is to investigate the endothelial progenitor cell CD 34 numbers in children with CKD on regular hemodialysis (HD) and detect their association with vascular stiffness. We recruited 25 children on regular HD, who were selected from the HD unit of Al-Zahraa Hospital, Al-Azhar University. Another group of 25 age and sex matched healthy children served as as controls. We investigated the number of EPC number (CD34) using flow cytometry, intima-media thickness (IMT), and the peak systolic velocity (PSV) of the main arteries including the (aorta, carotid, and femoral) arteries using Doppler ultrasound, this is in the same line with the routine and traditional investigations of the CV risk in the study groups. Children on regular HD have significantly lower EPC numbers (CD34 numbers) compared to their controls, the median and the inter equatorial range of CD34 was 57 (17-122) and five (3-6), respectively (P 0.001). Significant positive correlations were found between CD 34 and trigly...Continue Reading

Cardiovascular Disease Pathophysiology

Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.
