Conceptual
Abstract-Fortification of enriched cereal grain flour products with folic acid has drastically reduced the prevalence of deficient plasma folate status, a major determinant of plasma total homocysteine (tHcy) levels. We hypothesized that even more liberally defined “suboptimal” plasma folate status might no longer contribute importantly to the population attributable risk (PAR) for mild hyperhomocysteinemia, a putative atherothrombotic risk factor. We determined fasting plasma tHcy, folate, vitamin B12, and pyridoxal 5?-phosphate levels, along with serum creatinine and albumin levels, in 267 consecutive patients (aged 61±9 [mean±SD] years, 76.4% men and 26.6% women) with stable coronary artery disease (CAD) who were nonusers of vitamin supplements or had abstained from supplement use for at least 6 weeks before examination. Subjects were evaluated a minimum of 3 months after the implementation of flour fortification was largely completed. Relative risk estimates for the calculation of PAR were derived from a multivariable-adjusted logistic regression model with ?12 ?mol/L tHcy as the dependent variable and with age, sex, pyridoxal 5?-phosphate (continuous), albumin (continuous), <5 ng/mL folate, <250 pg/mL vitamin B12, and ?1.3 mg/dL creatinine as the independent variables. The prevalence of ?12 ?mol/L plasma tHcy was 11.2% (30 of 267 patients). PAR estimates (percentage) for ?12 ?mol/L tHcy were as follows: <5 ng/mL folate (<1%), <250 pg/mL vitamin B12 (24.5%), and ?1.3 mg/dL creatinine (37.5%). In the era of folic acid–fortified cereal grain flour, renal insufficiency and suboptimal vitamin B12 status (but not folate status) contribute importantly to the PAR for mild hyperhomocysteinemia among patients with stable CAD.
Ueland mais aussi al step one has just claimed an excellent meta-research away from 14 prospective education of the matchmaking between baseline total homocysteine (tHcy) accounts and (primarily) coronary artery disease (CAD) consequences when you look at the people-situated cohorts; so it meta-study are stated from the end from 1999. The brand new aggregate cousin exposure guess (out-of a total of 2786 times) each 5 ?mol/L change in tHcy quantity are 1.20 (95% CI step one.14 to just one.25). Nephrosclerosis, especially renal arteriolar hyalinization, 2 step three cuatro might have been in the general arteriosclerosis 2 and you may systematic 3 as well as subclinical CAD. 4 You will find a robust separate (inverse) relationship anywhere between glomerular filtration speed really influenced by both iohexol clearance 5 six or 51 Cr-EDTA approval eight and you may fast tHcy membership, and this border glomerular filtration prices on normative variety. A great surrogate to own glomerular filter price 8 and you will homocysteine age group, 9 creatinine is a huge determinant away from tHcy accounts into the CAD patients 10 11 and you may standard populations. a dozen When you look at the a people-established sample which have predominantly regular renal setting, fortification out-of graced cereal grain flour activities which have folic acidic significantly faster the fresh new frequency from deficient plasma folate status and you can mild hyperhomocysteinemia. 13 Such research examine starkly on limited impression that so it fortification coverage has had towards prevalence off lighter hyperhomocysteinemia one of persistent kidney transplant recipients, 14 whom act as a valid model toward hyperhomocysteinemia from persistent kidney deficit, typically. fifteen More over, kidney means gauged since the an easy creatinine devotion ‘s the major separate determinant away from tHcy levels inside all these 2 diligent groups that have mild so you can modest chronic renal deficiency. 14 fifteen Into the white of these cumulative conclusions, 13 fourteen fifteen i hypothesized you to definitely far more liberally defined “suboptimal” plasma folate updates might no lengthened lead importantly towards population attributable risk (PAR) getting lightweight hyperhomocysteinemia one of secure CAD customers. Properly, i reviewed fast plasma tHcy and you can serum creatinine in conjunction with the other depending determinants away from tHcy profile (ie, ages, sixteen sex, 16 B-supplement position, 16 and you will albumin 17 ) among 267 consecutive clients having clinically steady CAD, every one of who had been checked-out at the very least three to four weeks just after fortification out-of enriched cereal grains flour with folic acidic are mostly completed. 13
