A Study of Srum Homocysteine Level in Ischaemic Stoke
CONCLUSION: The present study revealed that hyperhomocysteinemia appears to be an important risk factor for ischemic stroke. It is therefore important to use serum homocysteine as an important tool to investigate all cases of ischemic stroke and if serum homocysteine is elevated patient should be put on multivitamins containing vitamin B12, folic acid and pyridoxine to reduce serum homocysteine levels.PMID:35443421

Preliminary analysis of immunoregulatory mechanism of hyperhomocysteinemia-induced brain injury in Wistar-Kyoto rats
In conclusion, the present study indicated that HHcy can promote inflammation by triggering Treg/Th17 immune imbalance to ameliorate the brain tissue damage.PMID:33790992 | PMC:PMC8005698 | DOI:10.3892/etm.2021.9914

Effects of Nutritional Supplements and Dietary Interventions on Cardiovascular Outcomes: An Umbrella Review and Evidence Map.
Conclusion: Reduced salt intake, omega-3 LC-PUFA use, and folate supplementation could reduce risk for some cardiovascular outcomes in adults. Combined calcium plus vitamin D might increase risk for stroke. Primary Funding Source: None. PMID: 31284304 [PubMed - as supplied by publisher]

B vitamins and cognition in subjects with small vessel disease: A Substudy of VITATOPS, a randomized, placebo-controlled trial
VITAmins TO Prevent Stroke (VITATOPS) study, a randomized, double-blind international multi-centre trial involving 8164 subjects in studying effect of lowering homocysteine level by daily administration of B-vitamins (2mg folic acid, 25mg vitamin B6, and 0.5mg vitamin B12) failed to demonstrate a positive effect of B-vitamins in reducing incidence of major vascular events and global cognition decline as measured by mini-mental state examination (MMSE) score [1,2]. However, assessment of cognition using MMSE alone has its limitations and a full neuropsychological assessment of different cognitive domains will provide more robust evidence.

Homocysteine and non-cardiac vascular disease.
Abstract Elevated homocysteine (Hcy) levels are predictors of cardiovascular disease (CVD). Hyperhomocysteinemia has also been associated with total and CVD mortality. However, whether Hcy is just a marker or plays a causal role in CVD remains to be elucidated. In this narrative review, we discuss the associations between Hcy and non-cardiac vascular diseases, namely stroke, peripheral artery disease (PAD), carotid artery disease, chronic kidney disease (CKD), atherosclerotic renal artery stenosis (ARAS), abdominal aortic aneurysm (AAA) and erectile dysfunction (ED). The effects of several drugs on Hcy levels are ...

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...

Incident Cancer in a Cohort of 3,247 Cancer Diagnosis Free Ischemic Stroke Patients
Conclusions: The annual rate of age-adjusted cancer incidence was higher among ischemic stroke patients compared with those in the general population. The odds of mortality were three folds higher among stroke survivors who developed incident cancer.Cerebrovasc Dis 2015;39:262-268

The effect of homocysteine-lowering with B-vitamins on osteoporotic fractures in patients with cerebrovascular disease: substudy of VITATOPS, a randomised placebo-controlled trial
Background: Homocysteine has been postulated as a novel, potentially reversible risk factor for osteoporosis and related fractures. We evaluated whether homocysteine-lowering therapy with B-vitamins in patients with symptomatic cerebrovascular disease reduced the incidence of osteoporotic fractures. Methods: VITAmins To Prevent Stroke (VITATOPS) was a prospective randomised double-blind placebo-controlled trial in which 8,164 patients with recent (within 7 months) stroke or transient ischemic attack were randomly allocated to double-blind treatment with one tablet daily of either placebo (n = 4,075) or B-vitamins (folic ac...

Effect of B Vitamins and Lowering Homocysteine on Cognitive Impairment in Patients With Previous Stroke or Transient Ischemic Attack: A Prespecified Secondary Analysis of a Randomized, Placebo-Controlled Trial and Meta-Analysis Clinical Sciences
Conclusions— Daily supplementation with folic acid, vitamin B6, and vitamin B12 to a self-selected clinical trial cohort of cognitively unimpaired patients with previous stroke or transient ischemic attack lowered mean tHcy but had no effect on the incidence of cognitive impairment or cognitive decline, as measured by the MMSE, during a median of 2.8 years.
