Decreased circulating endothelial progenitor cells as an early risk factor of subclinical atherosclerosis in systemic lupus erythematosus.

Objective: Endothelial progenitor cells (EPCs) play an important role in vascular damage repair and it has been suggested that a decreased number of these cells is associated with increased subclinical atherosclerosis. Our study aim was to evaluate whether the number of circulating EPCs in patients with SLE is associated with subclinical atherosclerosis, the presence of cardiovascular (CV) risk factors and SLE-specific factors.

Methods: Forty-six female SLE patients were included.

Increased arterial stiffness is independently associated with metabolic syndrome and damage index in systemic lupus erythematosus patients.

Objectives: We evaluated whether traditional or non-traditional cardiovascular (CV) risk factors and systemic lupus erythematosus (SLE)-related risk factors were associated with pathological arterial stiffness measured by pulse wave velocity (PWV) adjusted for patients' age and blood pressure.

Method: CV risk factors were measured in the 46 SLE female patients studied. Activity and organ damage were assessed by the SLE Disease Activity Index (SLEDAI) and the Systemic Lupus International Collaborative Clinics/American College of Rheumatology (SLICC/ACR) Damage Index, respectively.
