Abstract

The increased expression of the transmembrane protein CD40 on macrophages, endothelium, smooth muscle cells, platelet-monocyte conglomerate is connected with an enlarged risk of the occurrence of diseases of the cardiovascular system in the metabolic syndrome. was to establish whether metabolic syndrome in children can already be a precursor of cardiovascular diseases. The study was carried out on 35 children aged 10-18 years with the metabolic syndrome recognized according to the National Cholesterol Educational Program Adult Treatment Panel III (ATP III) criteria. The control group consisted of 26 healthy children without risk factors. In the examined children we evaluated BMI, the blood pressure, lipids, hsCRP, and the HOMA index. The analysis of the expression CD 40L (CD154) was performed with a three-color flow cytometer. The identification surrendered 104 cells. Statistical analysis was performed with use of U-Mann-Whitney test, for correlation analysis we used Spearman and Pearson tests. We observed an elevated expression of CD40 ligand on the surface on platelet-monocyte conglomerate in patients with the metabolic syndrome compared to healthy children (12.7 vs. 4.95%, p=0.0036). In addition, we found a statistically sig...Continue Reading

Atherosclerosis is the buildup of plaque on artery walls, causing stenosis which can eventually lead to clinically apparent cardiovascular disease. Find the latest research on atherosclerosis disease progression here.

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.
