Correlation between Low Folate Levels and Hyperhomocysteinemia, but not with Vitamin B12 in Hypertensive Patients.
INTRODUCTION: Hypertension is considered to be among the most important risk factors for cardiovascular and cerebrovascular diseases. In recent years, several investigators have reported that high plasma levels of total homocysteine (t-hcy) has a key role in the development of hypertension, and the deficiency of B complex vitamins could increase the risk of hypertension. The purpose of this study was to investigate the relationship between plasma homocysteine, folate and vitamin B12 in hypertensive patients. MATERIALS AND METHODS: In 116 patients with hypertension and 81 healthy subjects, total plasma homocysteine, vitamin B12 and folate levels were measured. RESULTS AND DISCUSSION: Homocys…
Relationship of fetuin-A with glomerular filtration rate and endothelial dysfunction in moderate-severe chronic kidney disease
Background: In end-stage renal disease, fetuin-A has been demonstrated to be reduced and inversely related to cardiovascular mortality. This study had 2 distinct aims. The first was to verify if circulating concentration of fetuin-A may depend on renal function in patients with chronic kidney disease (CKD). Furthermore, we analyzed the correlation of fetuin-A with the biomarker of endothelial dysfunction endothelin-1 (ET-1), and with the inflammatory cytokine interleukin-6 (IL-6). Methods: In 108 subjects with stage 3-5 CKD, plasma levels of fetuin-A, ET-1 and IL-6 were assayed. Patients were studied first as a whole group and then were divided according to stages of CKD and fetuin-A tertil…
Oxidative stress, inflammation and cardiovascular disease in chronic renal failure
Traditional risk factors such as hypertension, diabetes, dyslipidemia, obesity and metabolic syndrome, as well as additional nontraditional risk factors, can damage the kidney directly and by promoting intrarenal atherogenesis. Evidence indicates that increased oxidative stress and inflammation may mediate most of the effects of risk factors on the kidney. Clinical studies have demonstrated a relationship between oxidative stress and inflammatory biomarkers, and a few studies indicate an inverse correlation of oxidative stress biomarkers with estimated glomerular filtration rate (eGFR). Further, surrogate indexes of atherosclerosis such as intima-media thickness and aortic pulse wave veloci…
FOKI AND BSMI VITAMIN D RECEPTOR GENE POLYMORPHISMS, ARE THEY ASSOCIATED WITH INTIMA MEDIA THICKNESS IN ESSENTIAL HYPERTENSIVE INDIVIDUALS
Objective: Analyzing 25hydroxyvitaminD (25[OH]D) serum levels and common carotid intimamedia thickness (IMT) relationship, and evaluating the association of FokI and BsmI vitamin D receptor (VDR) gene polymorphisms with IMT in essential hypertensive patients were our study aims. Design and method: We enrolled seventyone essential hypertensive patients, 18–75 years old. Patients underwent clinical blood pressure (BP) measurement, 24 hour ambulatory blood pressure monitoring, routine blood test, 25[OH]D assay and common carotid IMT evaluation. FokI and BsmIVDRpolymorphisms were analyzed by polymerase chain reactionrestriction fragment length polymorphism (PCRRFLP).
