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 ainsi que al step one recently reported a great meta-study off fourteen prospective degree of your own dating between standard overall homocysteine (tHcy) accounts and you can (primarily) coronary artery situation (CAD) outcomes in the society-centered cohorts; so it meta-research was reported from prevent away from 1999. The fresh new aggregate relative risk estimate (off a maximum of 2786 circumstances) for every single 5 ?mol/L improvement in tHcy focus was 1.20 (95% CI step one.fourteen to one.25). Nephrosclerosis, particularly kidney arteriolar hyalinization, dos 3 4 has been associated with endemic arteriosclerosis dos and medical step three and subclinical CAD. 4 There was a strong separate (inverse) relationship between glomerular filtration rate individually influenced by often iohexol clearance 5 six otherwise 51 Cr-EDTA clearance seven and fast tHcy accounts, and this surrounds glomerular filtration rates regarding normative diversity. A good surrogate to own glomerular filtration rate 8 and you will homocysteine age group, 9 creatinine is a big determinant off tHcy membership when you look at the CAD patients ten eleven and you can general populations. a dozen In a populace-centered attempt that have predominantly regular kidney form, fortification out-of enriched cereal cereals flour points that have folic acid significantly less the new frequency out of deficient plasma folate status and you may lighter hyperhomocysteinemia. thirteen This type of study compare starkly with the very limited feeling you to definitely that it fortification plan has had to the incidence regarding lighter hyperhomocysteinemia certainly chronic kidney transplant users, 14 who act as a valid design to your hyperhomocysteinemia off persistent kidney insufficiency, in general. 15 Also, renal mode gauged because a straightforward creatinine commitment is the significant separate determinant off tHcy membership when you look at the each of these 2 diligent groups with mild to help you moderate persistent kidney deficiency. 14 15 For the light of these collective findings, thirteen 14 15 we hypothesized you to a whole lot more liberally discussed “suboptimal” plasma folate updates may no prolonged lead importantly with the people attributable risk (PAR) to possess lightweight hyperhomocysteinemia among steady CAD patients. Consequently, i reviewed fasting plasma tHcy and you can solution creatinine along side another founded determinants from tHcy membership (ie, ages, 16 sex, sixteen B-supplement condition, 16 and you can albumin 17 ) among 267 successive clients which have clinically stable CAD, each one of which was indeed checked-out at the very least three to four weeks shortly after fortification out-of enriched cereal grain flour which have folic acid is actually mainly completed. thirteen
