Association of low-grade inflammation and platelet activation in patients with hypertension with microalbuminuria.
2008
Increased levels of sCD40L (soluble CD40 ligand) have been associated with enhanced in vivo platelet activation, and may represent a molecular link between inflammation and a prothrombotic state. The aim of the present study was to analyse the relationship between platelet activation, endothelial dysfunction, low-grade inflammation and sCD40L in patients with hypertension with or without MA (microalbuminuria). A cross-sectional comparison of sCD40L levels was performed in 25 patients with MH (essential hypertension with MA) pair-matched for gender and age with 25 patients with EH (essential hypertension) and 25 HS (healthy subjects with normotension). Circulating levels of CRP (C-reactive protein), a marker of inflammation, sP-selectin (soluble P-selectin), a marker of in vivo platelet activation, and ADMA (asymmetric dimethylarginine) and vWF (von Willebrand factor), markers of endothelial dysfunction, were analysed in each subject. sCD40L levels were increased in patients with MH compared with either patients with EH ( P P P P P P P
