Abstract

We have recently demonstrated the diagnostic value of a new immunophenotype of blood endothelial progenitor cells (EPCs=CD45neg/CD34pos/CD144pos) and endothelial microparticles (EMPs=CD45neg/CD144pos/AnnexinVpos) in patients with arterial erectile dysfunction (ED) according to severity of cavernous arterial insufficiency evaluated through penile Doppler. The aim of this study was to evaluate both EPCs and EMPs in patients with arterial ED and metabolic syndrome (MetS), comparing these patients with another group of patients without MetS and ED and a third group with MetS but without ED. For this study 50 patients with arterial ED and MetS were selected (age: 55.0±3.0 years; range: 47–60). A group of age-matched (age: 54.0±2.0 years; range: 44–60) patients without arterial ED and MetS (n=30), and another group of age-matched (age: 57.0±4.0 years; range: 40–62) patients with MetS but without ED (n=20) represented the control groups. EPCs and EMPs were significantly higher in patients compared with other groups (P<0.01). Both EPCs and EMPs correlated positively with the age, body mass index, and score of international index of ED (version five items) and with the following cavernous artery indices: peak systolic velocity, acceleration time and intima-media thickness. Among control groups patients with MetS but without ED showed serum concentrations of EPCs and EMPs significantly higher (P<0.05) compared with patients without MetS and ED. Patients with arterial ED and MetS have higher EPCs and EMPs compared with patients with MetS but without ED and patients without MetS and ED.
