Early Detection of Subclinical Atherosclerosis: Hyperhomocysteinemia as a Promising Marker in Adolescents With Vitamin B Deficiency
Cureus. 2023 Jul 8;15(7):e41571. doi: 10.7759/cureus.41571. eCollection 2023 Jul.ABSTRACTIn recent decades, the increased incidence of cardiovascular disease (CVD) mortality among young adults has raised concerns. Although clinical manifestations of CVD typically occur later in life, the underlying pathological processes emerge early on. This review article summarizes the association between vitamin B deficiency-induced hyperhomocysteinemia and subclinical atherosclerosis in adolescents. Numerous studies have demonstrated that elevated homocysteine levels are an independent risk factor for endothelial dysfunction (ED) and ...

Genetics of hyperhomocysteinemia and 1-carbon metabolism: implications for retinal structure and eye functions.
Abstract Homocysteine (Hcy); a sulfur-containing non-proteinogenic amino acid is generated as a metabolic intermediate. Hcy constitutes an important part of the "1-carbon metabolism" during methionine turnover. Elevated levels of Hcy known as hyperhomocysteinemia (HHcy) results from vitamin B deficiency, lack of exercise, smoking, excessive alcohol intake, high fat and methionine rich diet, and the underlying genetic defects. These factors directly affect the "1-carbon metabolism (methionine-Hcy-folate)" of a given cell. In fact, the Hcy levels are determined primarily by dietary intake, vitamin status, and the ge...

Vitamin B may reduce risk of stroke
Researchers have uncovered evidence that suggests vitamin B supplements could help to reduce the risk of stroke, according to a study published in the journal Neurology. Vitamin B supplements are said to be beneficial for many health issues, including stress, anxiety, depression, dementia, Alzheimer's disease and heart disease. However, according to Xu Yuming of Zhengzhou University in Zhengzhou, China, previous studies have conflicting findings regarding the use of vitamin B supplements and stroke or heart attack...
