Low serum levels of 25-hydroxyvitamin D (25(OH)D) have been associated with a higher frequency of risk factors and cardiovascular disease. The aim of this study is to evaluate the association of 25(OH)D, cardiovascular risk factors, and subclinical atherosclerosis in systemic lupus erythematosus (SLE) patients. Forty-seven female SLE patients were studied. Data collected included demographics, SLE activity, disease damage, cardiovascular risk factors, and markers of subclinical atherosclerosis. Patient treatments and vitamin D and calcium supplementation (VitD-Ca) were recorded. Vitamin D deficiency was defined as serum 25(OH)D

Cystatin C (CysC) is a protein considered as an excellent marker of renal function, and it has been suggested as an independent predictor of cardiovascular (CV) risk. We evaluated the association of serum CysC with renal function, CV risk factors, inflammation, and subclinical atherosclerosis in Systemic Lupus Erythematosus (SLE) patients. Sixty-one SLE female patients were selected according to estimated glomerular filtration rate (GFR) > 60 ml/min/1.73m2. Renal function parameters, SLE specific factors, CV risk factors, and inflammatory markers were assessed. Subclinical atherosclerosis was assessed by measuring the carotid-femoral pulse wave velocity (PWV) by Doppler velocimetry. Serum CysC concentration was measured using a particle-enhanced immunonephelometric assay that established 0.59–1.01 mg/l as reference values. Patients with high CysC showed significantly altered creatinine, microalbuminuria, and GFR in addition to a significant higher presence of traditional CV risk factors such as arterial hypertension (p
