Role of oxidative stress in cardiovascular effects of anemia treatment with erythropoietin in predialysis patients with chronic kidney disease.

Background/aim: Oxidative stress (OS) is involved in left ventricular hypertrophy (LVH). Short-term treatment with erythropoietin (EPO) in chronic kidney disease (CKD) complicated by anemia and LVH is associated with a reduction in left ventricular mass (LVM). We proposed to assess whether the pro-oxidant status of CKD influences these outcomes.

Silent cerebral white matter lesions and their relationship with vascular risk factors in middle-aged predialysis patients with CKD.

Background: Silent cerebral white matter lesions are observed on magnetic resonance imaging (MRI) scans in elderly people, and they are related to vascular risk factors, particularly hypertension. No data on the prevalence and risk factors of white matter lesions in patients with chronic kidney disease (CKD) are available. The aim is to analyze the prevalence of white matter lesions and their determinants in this population.
