Abstract
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 recently stated an excellent meta-studies from 14 potential studies of your own relationships between standard overall homocysteine (tHcy) profile and you may (primarily) coronary artery disease (CAD) outcomes within the populace-depending cohorts; which meta-research was advertised from end away from 1999. New aggregate relative exposure imagine (out-of all in all, 2786 times) for each 5 ?mol/L improvement in tHcy quantity was step 1.20 (95% CI step one.14 to just one.25). Nephrosclerosis, particularly kidney arteriolar hyalinization, dos step 3 4 has been of this systemic arteriosclerosis dos and you will systematic 3 including subclinical CAD. 4 Discover an effective separate (inverse) relationship ranging from glomerular filter rates yourself influenced by sometimes iohexol approval 5 six or 51 Cr-EDTA approval seven and you can fasting tHcy levels, which encompasses glomerular filtration pricing from the normative range. Good surrogate to possess glomerular filtration rates 8 and you may homocysteine age group, 9 creatinine is a significant determinant regarding tHcy profile inside CAD people 10 eleven and standard communities. 12 Inside an inhabitants-dependent decide to try with predominantly normal kidney setting, fortification off enriched cereal cereals flour activities with folic acidic dramatically shorter the fresh incidence out of deficient plasma folate position and you will light hyperhomocysteinemia. 13 This type of analysis contrast starkly for the limited impression you to definitely it fortification policy has received with the frequency out-of lightweight hyperhomocysteinemia one of chronic kidney transplant users, fourteen who act as a valid design to your hyperhomocysteinemia off persistent kidney deficiency, generally. 15 Moreover, kidney mode measured just like the a straightforward creatinine devotion ‘s the major separate determinant away from tHcy membership into the each of these 2 diligent groups with mild so you can modest persistent renal deficiency. 14 15 From inside the white of such cumulative results, 13 fourteen 15 i hypothesized you to even more liberally defined “suboptimal” plasma folate updates might no lengthened lead notably for the inhabitants attributable risk (PAR) having mild hyperhomocysteinemia among steady CAD patients. Properly, we examined fast plasma tHcy and solution creatinine combined with another depending determinants regarding tHcy accounts (ie, age, sixteen sex, sixteen B-supplement reputation, 16 and you will albumin 17 ) certainly 267 straight patients having clinically secure CAD, all of whom were tested at the least 3 to 4 months after fortification regarding enriched cereal grain flour that have folic acidic is actually mostly done. 13
