Aim
To evaluate the number of EPCs in the blood of patients with PsV, characterized by the expression of specific cell surface markers, including CD45-, CD31+, CD34+ and CD133+. Material and
Conclusions
The results of our studies indicate that patients with psoriasis showed an increased mobilization of EPCs compared with healthy individuals which correlated negatively with disease severity.
Material and methods
A total of 49 patients suffering from PsV and 40 healthy volunteers were enrolled in the study. The number of EPCs in each of the volunteers' whole blood samples was measured with a FACSCalibur flow cytometer using monoclonal antibodies directed against antigens specific for EPCs.
Methods
A total of 49 patients suffering from PsV and 40 healthy volunteers were enrolled in the study. The number of EPCs in each of the volunteers' whole blood samples was measured with a FACSCalibur flow cytometer using monoclonal antibodies directed against antigens specific for EPCs.
Results
The number of EPCs was significantly higher in patients with psoriasis compared with the controls (p = 0.0007) and inversely correlated with disease severity assessed by PASI score (R = -0.2935, p = 0.0407). Statistical analysis did not show significant relations between the count of EPCs and age, body mass index, gender, disease duration, blood pressure, extent of itching, severity and frequency of pruritus, presence of bruises, vitamin D supplementation and smoking habit. Conclusions: The results of our studies indicate that patients with psoriasis showed an increased mobilization of EPCs compared with healthy individuals which correlated negatively with disease severity.
