Association of plasma homocysteine level with vaso-occlusive crisis in sickle cell anemia patients of Odisha, India
AbstractVascular complications of sickle cell anemia (SCA) are influenced by many factors. Elevated plasma homocysteine (Hcy) is supposed to be an independent risk factor and is either genetic or nutritional origin. The present study evaluated the plasma Hcy level, MTHFR C677T gene polymorphism, effect of folic acid (FA) supplementation ‚ and hemato-biochemical parameters in SCA and their effect on the vaso-occlusive crisis (VOC) in SCA patients of an Asian-Indian haplotype population. One hundred twenty cases of SCA (HbSS) and 50 controls with normal hemoglobin(HbAA) were studied. It was found that the plasma Hcy level ...

Physiological and pathophysiological significance of vitamin B9. Summary on the occasion of the 30-year introduction of folic acid as a dietary supplement.
Abstract Vitamin B9, also known as folate, can be found in natural and synthetic forms, mostly in vegetables or folic acid containing food supplements. By participating in the proper cell development and division, its presence is indispensable for certain basic metabolic processes. The decreased folate level of the body, mainly caused by environmental and hereditary factors as well as aging, can lead to genetic, epigenetic and metabolic changes. It can be related to the development of megaloblastic anemia, various cardiovascular diseases (such as atherosclerosis, stroke) obstetrical complications (such as abruptio...

Folic acid deficiency enhanced microglial immune response via the Notch1/nuclear factor kappa B p65 pathway in hippocampus following rat brain I/R injury and BV2 cells.
Abstract Recent studies revealed that folic acid deficiency (FD) increased the likelihood of stroke and aggravated brain injury after focal cerebral ischaemia. The microglia-mediated inflammatory response plays a crucial role in the complicated pathologies that lead to ischaemic brain injury. However, whether FD is involved in the activation of microglia and the neuroinflammation after experimental stroke and the underlying mechanism is still unclear. The aim of the present study was to assess whether FD modulates the Notch1/nuclear factor kappa B (NF-κB) pathway and enhances microglial immune response in a rat m...

A genetic deficiency in folic acid metabolism impairs recovery after ischemic stroke.
Abstract Stroke is a leading cause of disability and death world-wide and nutrition is a modifiable risk factor for stroke. Metheylenetetrahydrofolate reductase (MTHFR) is an enzyme involved in the metabolism of folic acid, a B-vitamin. In humans, a polymorphism in MTHFR (677C→T) is linked to increased risk of stroke, but the mechanisms remain unknown. The Mthfr+/- mice mimic a phenotype described in humans at bp677. Using this mouse model, the aim of this study was to investigate the impact of MTHFR deficiency on stroke outcome. Male Mthfr+/- and wildtype littermate control mice were aged (~1.5-year-old) and tr...

Influence of renal function on the association between homocysteine level and risk of ischemic stroke.
We examined whether the association between total homocysteine (tHCY) and risk of ischemic stroke (IS) varies depending on renal function to gain insight into why tHCY-lowering vitamins do not reduce the incidence of cardiovascular disease in clinical trials. We analyzed data from 542 IS patients with large artery atherosclerosis (LAA) or small artery occlusion (SAO) after stratification by estimated glomerular filtration rate (eGFR) to evaluate renal function. We found that tHCY level was positively associated with the occurrence of IS in both LAA (OR: 1.159, 95% CI: 1.074-1.252, P<0.001) and SAO (OR: 1.143, 95% CI: 1....

A specific dietary intervention to restore brain structure and function after ischemic stroke
Occlusion of the middle cerebral artery (MCAo) is among the most common causes of ischemic stroke in humans. Cerebral ischemia leads to brain lesions existing of an irreversibly injured core and an ischemic boundary zone, the penumbra, containing damaged but potentially salvageable tissue. Using a transient occlusion (30 min) of the middle cerebral artery (tMCAo) mouse model in this cross-institutional study we investigated the neurorestorative efficacy of a dietary approach (Fortasyn) comprising docosahexaenoic acid, eicosapentaenoic acid, uridine, choline, phospholipids, folic acid, vitamins B12, B6, C, and E, and seleni...

Relationship Between Nutritional Factors and Hip Bone Density in Individuals with Chronic Stroke
AbstractThe aim of this study was to investigate the relationship between dietary habits and hip bone health in community-dwelling individuals with chronic stroke. The usual dietary intake of 94 individuals with chronic stroke (30 women, mean age: 59.0  years) was assessed by a 3-day food record within a single week. Dual-energy X-ray absorptiometry was used to measure bone mineral density (BMD) at both hips. The results showed that low hip bone mass was found in 59 and 50 of the participants on the affected and unaffected side, respectively. The mean hip BMD was also significantly lower on the affected side than the unaf...

B-vitamin and choline supplementation increases neuroplasticity and recovery after stroke.
Abstract Folates are B-vitamins that play an important role in brain function. Dietary and genetic deficiencies in folate metabolism result in elevated levels of homocysteine which have been linked to increased risk of developing a stroke. Reducing levels of homocysteine before or after a stroke through B-vitamin supplementation has been a focus of many clinical studies, however, the results remain inconsistent. Animal model systems provide a powerful mechanism to study and understand functional impact and mechanisms through which supplementation affects stroke recovery. The aim of this study was to understand the...

Association between hyperhomocysteinemia and stroke with atherosclerosis and small artery occlusion depends on homocysteine metabolism-related vitamin levels in Chinese patients with normal renal function
This study was conducted to investigate the role of different homocysteine metabolism-related vitamin (HMRV) levels in the correlation between hyperhomocysteinemia (HHCY) and ischemic stroke (IS) subtypes. Three hundred and forty-eight IS patients manifesting different vascular subtypes were subclassified on the basis of HMRV deficiencies. Correlation between HHCY and IS subtypes was investigated in all the subgroups. In this study, HHCY was significantly correlated with the IS subtypes in large artery atherosclerosis (OR 1.126, 95%CI: 1.051  ~ 1.206,P = 0.001) and small artery occlusion (OR 1.105, 95%CI: 1.023 ~ 1.1...

Efficacy of folic acid in primary prevention of stroke among patients with hypertension in China
After folic acid had been documented to reduce birth defects, the United States mandated folic acid food fortification in grain products in 1996 and implemented the policy by 1998.1 Around this time, controversy surfaced on adverse effects of folic acid, namely its possible role in promoting carcinogenesis. However, data over the next decade failed to provide sufficient evidence to support such a claim.1,2 In addition to decreasing neural tube defects, folic acid supplementation has been hypothesized to decrease the risk of stroke and cardiovascular events; however, among the multiple randomized controlled studies thus far...

Folic acid, a B vitamin, lowers stroke risk in people with high blood pressure
If you’re among the one in three American adults with high blood pressure, be sure you’re getting plenty of the B vitamin known as folate. Doing so may lower your odds of having a stroke, an often disabling or deadly event linked to high blood pressure, a new study suggests. Folate occurs naturally in many foods, but especially green leafy vegetables, beans, and citrus fruits. Here in the United States, add to the list most grain products, including wheat flour, cornmeal, pasta, and rice. They are fortified with the synthetic version of folate, known as folic acid. That’s not the case in many countries ar...
