Objective: Patients with systemic lupus erythematosus (SLE) often suffer from systemic inflammation and have higher risk of atherosclerosis which could be detected early by their vascular stiffness. Our objective was to study the relationship in Apo-B levels and vascular stiffness determined by brachial-ankle pulse wave velocity (baPWV) in patients with systemic lupus erythematosus (SLE)
Methods: Eighty-seven Thai SLE subjects were studied. Fasting blood was collected for creatinine, glucose, lipid profiles including Apo-B and Apo-A1. BaPWV was measured by non-invasive vascular screening device. Pearson correlation and stepwise-linear regression were used for the analysis.
Results: The average age of subjects was 36.69+10.85 years. Mean value for baPWV was 1,332+274.12 cm/s. Thirty six percent of patients were classified into increased vascular stiffness group as defined by baPWV greater than 1,400 cm/s. Mean Apo-B level in normal vascular stiffness and increased vascular stiffness group were 94.32 + 24.81 and 105.02 + 31.45 mg/dl. There were correlation of baPWV and age, systolic BP, diastolic BP and creatinine clearance. Apo-B tended to associate with baPWV (p=0.06) whereas LDL-C did not (p=0.2). By multiple regression analysis, systolic BP, age and Apo-B were the significant predictors of baPWV.
Conclusions: Apo-B level associated with vascular stiffness independent of other factors in Thai SLE subjects.
