چکیده

The prevalence of subclinical deficiencies of folate and vitamin B6 in India is high and preliminary investigation showed higher mean plasma total homocysteine level in Indians compared with the values reported for western populations. The present study was carried out in 40 apparently normal men to examine the relationship between plasma total homocysteine level and folate and vitamin B6 status. The mean plasma homocysteine level was high and was inversely related to folate status as judged by red blood cells or plasma folate concentrations. There was no significant relationship between fasting homocysteine level and vitamin B6 status.

Influence of age, sex and vitamin status on fasting and post-methionine load plasma homocysteine levels.

BACKGROUND AND OBJECTIVES To investigate the effects of age, sex and vitamin status on total plasma homocysteine (tHCy), both after fasting (FtHCy) and two hours post-methionine load (PML-tHCy). The secondary aim was to determine the reference values for FtHCy and PML-tHCy. DESIGN AND METHODS A cohort of apparently healthy volunteers underwent blood sampling for FtHCy, PML-tHCy, creatinine, s...

Betaine and folate status as cooperative determinants of plasma homocysteine in humans.

OBJECTIVE Two published studies have demonstrated that betaine in the circulation is a determinant of plasma total homocysteine, but none had sufficient power to investigate the possible effect modification by folate status. METHODS AND RESULTS We measured homocysteine, betaine, folate, vitamin B(6), and related compounds in serum/plasma from 500 healthy men and women aged 34 to 69 years befo...

Homocysteine metabolism and risk of myocardial infarction: relation with vitamins B6, B12, and folate.

Elevated plasma homocyst(e)ine levels are an independent risk factor for vascular disease. In a case-control study, the authors studied the associations of fasting plasma homocyst(e)ine and vitamins, which are important cofactors in homocysteine metabolism, with the risk of myocardial infarction. The cases were 130 Boston area patients hospitalized with a first myocardial infarction and 118 pop...

Background: Diabetes mellitus is the most common cause of renal failure, blindness, non- traumatic amputation and neuropathy. Homocysteine, a sulfurated amino acid, has a close correlation with Methionine and Cysteine. The conversion of Methionine to Homocysteine and Cysteine is required coenzymes like vitamin B6, B12 and Folate. The effect of Metformin on serum Homocysteine level by decreasing...

Association between plasma homocysteine concentrations and extracranial carotid-artery stenosis.

BACKGROUND Epidemiologic studies have identified hyperhomocysteinemia as a possible risk factor for atherosclerosis. We determined the risk of carotid-artery atherosclerosis in relation to both plasma homocysteine concentrations and nutritional determinants of hyperhomocysteinemia. METHODS We performed a cross-sectional study of 1041 elderly subjects (418 men and 623 women; age range, 67 to 9...
