Daily Folic Acid and/or Vitamin B12 Supplementation Between 6 and 30 Months of Age and Cardiometabolic Risk Markers After 6-7 Years: A Follow-Up of a Randomized Controlled Trial. J Nutr 2023; 153:1493-1501. [PMID: 36889645 PMCID: PMC10196576 DOI: 10.1016/j.tjnut.2023.03.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2022] [Revised: 02/25/2023] [Accepted: 03/02/2023] [Indexed: 03/08/2023] Open
Abstract
BACKGROUND Deficiencies of vitamin B12 and folate are associated with elevated concentrations of metabolic markers related to CVDs. OBJECTIVES We investigated the effect of supplementation of vitamin B12 with or without folic acid for 6 mo in early childhood on cardiometabolic risk markers after 6-7 y. METHODS This is a follow-up study of a 2 × 2 factorial, double-blind, randomized controlled trial of vitamin B12 and/or folic acid supplementation in 6-30-mo-old children. The supplement contained 1.8 μg of vitamin B12, 150 μg of folic acid, or both, constituting >1 AI or recommended daily allowances for a period of 6 mo. Enrolled children were contacted again after 6 y (September 2016-November 2017), and plasma concentrations of tHcy, leptin, high molecular weight adiponectin, and total adiponectin were measured (N = 791). RESULTS At baseline, 32% of children had a deficiency of either vitamin B12 (<200 pmol/L) or folate (<7.5 nmol/L). Combined supplementation of vitamin B12 and folic acid resulted in 1.19 μmol/L (95% CI: 0.09; 2.30 μmol/L) lower tHcy concentration 6 y later compared to placebo. We also found that vitamin B12 supplementation was associated with a lower leptin-adiponectin ratio in subgroups based on their nutritional status. CONCLUSIONS Supplementation with vitamin B12 and folic acid in early childhood was associated with a decrease in plasma tHcy concentrations after 6 y. The results of our study provide some evidence of persistent beneficial metabolic effects of vitamin B12 and folic acid supplementation in impoverished populations. The original trial was registered at www. CLINICALTRIALS gov as NCT00717730, and the follow-up study at www.ctri.nic.in as CTRI/2016/11/007494.

[PMID: 35420248 PMCID: PMC9088336 DOI: 10.1002/ppul.25920] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/24/2022] [Revised: 03/15/2022] [Accepted: 04/09/2022] [Indexed: 12/15/2022]
Abstract
BACKGROUND Thrombosis and embolism are possible complications in coronavirus disease 2019 (COVID)-19-positive pediatric patients. Although the risk is lesser in children than it is in adults, it does exist during acute infection and multi-inflammatory syndrome in children. Biomarkers such asd-dimer, prothrombin time, and fibrinogen degradation products are ineffective at detecting disease severity. Homocysteine (Hcy) is a prothrombotic factor that has been reported to be higher in adult COVID-19 patients, leading to speculation that it could be used as a biomarker for disease severity. PURPOSE To detect the correlation between serum total homocysteine (tHcy) level and the severity of COVID-19 in pediatrics. METHODS A cross-sectional study was conducted on 40 children with COVID-19 and 40 healthy control subjects. Serum tHcy was measured by enzyme-linked immunosorbent assay and correlated with the clinical, laboratory, and radiological parameters of the patients. RESULTS The median serum tHcy level in COVID-19 patients was 27.5 (interquartile range [IQR]: 23-31.75) μmol/L, while that in the controls was 1.8 (IQR: 1.6-1.875) μmol/L. There was a statistically significant increase in the tHcy level in cases compared to controls (p < 0.001). There was a statistically significant positive correlation between serum tHcy and d-dimer, ferritin, alanine transaminase, aspartate transaminase, blood urea nitrogen, and a highly significant positive correlation between tHcy and COVID-19 reporting and data system score, pediatric intensive care unit admission, and the disease severity classification. CONCLUSION Hcy could be a biomarker of importance in predicting the severity of COVID-19 in pediatrics.

Abstract
Hyperhomocysteinemia is an independent risk factor for atherosclerosis, even in early childhood. A mutation in genes which code homocysteine metabolism enzymes or deficiency of specific vitamin cofactors may cause hyperhomocysteinemia. Vitamin B complex has been correlated with serum homocysteine levels. Any abnormality in its metabolism or nutritional deficiency may lead to hyperhomocysteinemia. Both vitamin B complex and homocysteine levels are partly genetically determined. Specifically, the most studied polymorphism is 677T-C in exon 5 of the 5,10- methylenetetrahydrofolate reductase (MTHFR) gene, which plays an important role in folate's metabolism. This polymorphism has been shown correlated with hypertension and cardiovascular disease. Polymorphisms in methylenetetrahydrofolate dehydrogenase (NADP+ dependent) 1-like (MTHFD1L) gene have also been correlated with increased risk for coronary artery disease. Other common serious polymorphisms regard the area with high linkage disequilibrium, which included the neuroblastoma breakpoint family, NBPF3 gene, and ~ 12-50 kb upstream of the tissue nonspecific alkaline phosphatase gene. Finally, the polymorphisms which have been mostly associated with vitamin B12 concentration are the rs11254363 polymorphism at intron 52 of the intrinsic factor vitamin B12 receptor of the CUBN and the rs526934 polymorphism at intron 8 of transcobalamin I. To sum up, several polymorphisms have already been associated with vitamin B complexes and therefore homocysteine level, which highlights the complex nature of vitamin B genetics.

Abstract
Increased plasma homocysteine is a risk factor for several pathological disorders. The present review focused on the role of homocysteine (Hcy) in different population groups, especially in risk conditions (pregnancy, infancy, old age), and on its relevance as a marker or etiological factor of the diseases in these age groups, focusing on the nutritional treatment of elevated Hcy levels. In pregnancy, Hcy levels were investigated in relation to the increased risk of adverse pregnancy outcomes such as small size for gestational age at birth, preeclampsia, recurrent abortions, low birth weight, or intrauterine growth restriction. In pediatric populations, Hcy levels are important not only for cardiovascular disease, obesity, and renal disease, but the most interesting evidence concerns study of elevated levels of Hcy in autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD). Finally, a focus on the principal pathologies of the elderly (cardiovascular and neurodegenerative disease, osteoporosis and physical function) is presented. The metabolism of Hcy is influenced by B vitamins, and Hcy-lowering vitamin treatments have been proposed. However, clinical trials have not reached a consensus about the effectiveness of vitamin supplementation on the reduction of Hcy levels and improvement of pathological condition, especially in elderly patients with overt pathologies, suggesting that other dietary and non-dietary factors are involved in high Hcy levels. The importance of novel experimental designs focusing on intra-individual variability as a complement to the typical case-control experimental designs and the study of interactions between different factors it should be emphasized.

Abstract
The Global Registry of Acute Coronary Events (GRACE) risk score independently predicts major adverse cardiac events (MACEs) in patients with acute coronary syndrome (ACS). This study aims to evaluate whether the level of plasma homocysteine in addition to the GRACE score enhances the predictive value for MACEs in patients with acute coronary syndrome.A total of 361 patients with ACS evaluated at our hospital were included in the study and tested for blood homocysteine levels. We recorded 40 (11.1%) instances of MACE during a median follow-up of 43.3 months (quartile 40.6-44.4 months), including 29 cases (8.0%) of all-cause death and 11 cases (3.1%) of nonfatal myocardial infarction.The GRACE score was significantly associated with homocysteine levels, and multivariate Cox regression analysis showed that both the GRACE risk score and homocysteine content were independent predictors of MACEs (HR 2.63; 95% confidence interval (CI) 1.54 to 4.49; P < .001 and 2.27; 1.06 to 4.86; P = .035, respectively). Moreover, meta-analysis showed that as the homocysteine level increased, the incidence of MACEs also increased (log-rank 8.41; P = .015). GRACE scores adjusted by homocysteine level increased the area under the curve (AUC) from 0.78 to 0.83 (P = 0.006).Blood homocysteine levels are significantly associated with the GRACE risk score, and using both parameters can further improve risk stratification in patients with acute coronary syndrome.

Abstract
BACKGROUND AND AIMS The high number of negative opinions from the European Food Safety Authority (EFSA) to the requests for authorization of health claims is largely due to the design of human intervention studies, including the inappropriate choice of outcome variables (OVs) and of their methods of measurement (MMs). The present manuscript reports the results of an investigation aimed to collect, collate and critically analyse the information in relation to claimed effects, OVs and MMs, in the context of protection against oxidative damage and cardiovascular health compliant with Regulation 1924/2006. METHODS AND RESULTS Claimed effects, OVs and the related MMs were collected from EFSA Guidance documents and applications for authorization of health claims under Articles 13.5 and 14. The OVs and their MMs were evaluated only if the claimed effect was sufficiently defined and was considered beneficial by EFSA. The collection, collation and critical analysis of the relevant scientific literature consisted in the definition of the keywords, the PubMed search strategies and the creation of databases of references. The critical analysis of the OVs and their MMs was performed on the basis of the literature review and was aimed at defining the appropriateness of OVs and MMs in the context of the specific claimed effects. CONCLUSIONS The information provided in this document could serve to EFSA for the development of further guidance on the scientific requirements for health claims, as well as to the stakeholders for the proper design of human intervention studies aimed to substantiate such health claims.

Abstract
Abstract
Increased levels of homocysteine (HCYS) represent a risk factor for a series of physiopathological conditions: mental retardation, cardiovascular and neurodegenerative diseases, Parkinson's and Alzheimer's disease, depression, osteoporosis, endothelial dysfunction and inhibition of cell proliferation. This paper aims to present the pathophysiological implications of HCYS and the correlation of hyperhomocysteinemia (H-HCYS) with critical condition in the intensive care unit (ICU). Hypovitaminosis B and folate deficiency is directly involved in the inhibition of HCYS metabolism and the accumulation of HCYS in the plasma and tissues. Critically ill patients are more prone to H-HCYS due to hypermetabolism and accelerated synthesis produced by reactive oxygen species (ROS). In conclusion it can be affirmed that the determination and monitoring of HCYS plasma levels may be of interest in optimizing the therapy for critically ill patients. Moreover, by controlling HCYS levels, and implicitly the essential cofactors that intervene in the specific biochemical pathways, such as vitamin B6, vitamin B12 and folic acid can provide a diversified and personalized treatment for each patient.

Abstract
Homocysteine is an amino acid that is produced from the metabolic demethylation of dietary methionine. It has gained arising attention for its association with increased risk of myocardial infarction, stroke and venous thromboembolism. Erectile dysfunction (ED), especially for vasculogenic ED, is a vascular disorder of cavernosal vascular bed. In this prospective pilot case-control study, we investigated plasma homocysteine levels in 32 ED patients and 20 healthy control men. Related patients characteristics including age, weight, height, marital status, smoking and drinking status, level of education were collected and analysed as well as penile colour Doppler ultrasound parameters. ED patients were further categorised into mild, moderate and severe ED based on 5-item of the International Index of Erectile Function. Higher homocysteine levels were observed in ED patients as compared with controls (p < .05). A multivariate logistic regression with likelihood ratio test revealed that homocysteine and penile peak systolic blood flow velocity (PSV) levels posed significant indicators for ED (chi-square of likelihood ratio = 20.42, df = 2, p < .005) as well as moderate and severe ED occurrence (chi-square of likelihood ratio = 28.50, df = 2, p < .005). The threshold value of homocysteine concentration to discriminate ED and control subjects was 12.65 μmol/L by performing receiver operating characteristic curve analyses. These data suggested that elevation of homocysteine levels was associated with an increased risk of ED.

Abstract
BACKGROUND/OBJECTIVES Cardiovascular diseases is a major cause of death and is responsible for 23.8% of deaths in Korea. Clinical symptoms manifest in adulthood, but susceptibility begins in utero. Elevated homocysteine levels and adiposity might be linked to a greater risk in children as well as adults. We hypothesized that those who have simultaneous risk for folate and adiposity would be affected with elevated homocysteine levels at 3 years of age. SUBJECTS/METHODS From the ongoing birth cohort at Ewha Womans University Mok-Dong Hospital, we compared adiposity parameters, serum homocysteine, and folate levels in 238 children (118 boys and 120 girls) at three years of age. The relationship between birth outcome, current weight and body mass index (BMI), postnatal growth, and homocysteine level were assessed using correlation and general linear model. Additionally, we assessed the combined effect between blood folate status and adiposity on current homocysteine levels. RESULTS Birth characteristics were not correlated with homocysteine. Current weight, BMI, upper-arm circumference, skinfold thickness, waist circumference, and hip circumference were positively correlated with homocysteine at three years of age (P < 0.05). Folate level was negatively correlated with homocysteine at three years of age (P < 0.0001). A relative high anthropometric measure which is compatible with adiposity and low folate level was associated with high homocysteine levels. CONCLUSION We found a combined effect of adiposity and folate levels with homocysteine levels at three years of age. This implicates the beneficial role of folate supplementation in the high-risk population at an early age.
