摘要高同型半胱氨酸血症与多种疾病的发生发展，如心脑血管疾病、高血压、糖尿病、肾脏疾病、妊娠等疾病密切相关，几乎影响全身的各个器官，通过氧化损伤、DNA甲基化和含硫化合物代谢异常等多种机制影响细胞的功能、蛋白质的合成与调控，进而导致组织和器官的病理变化。总同型半胱氨酸代谢异常的诱因与基因、营养、疾病等关系密切，因此，本专家共识基于回顾分析近30年的国内外研究文献和循证医学的证据，结合我国人群特点，本专家共识建议将总同型半胱氨酸≥10μmol/L定义为高同型半胱氨酸血症；根据同型半胱氨酸相关基因的检测结果和总同型半胱氨酸的水平，通过调整饮食结构和/或使用膳食补充剂包括甜菜碱和B族维生素以及相关辅助因子的营养素补充剂等方法降低总同型半胱氨酸水平，以期显著减缓相关疾病的发展进程。推荐开展与同型半胱氨酸相关的检测指标，以明确同型半胱氨酸升高的原因，进而指导临床的精准干预措施，有效改善同型半胱氨酸水平，实现预防疾病发生或延缓疾病进展的目的。

Abstract：High homocysteine levels, and a variety of disease development, such as cardiovascular disease, hypertension, diabetes, and closely related diseases such as kidney disease, pregnancy, almost affect the whole body organs, through oxidative damage, DNA methylation and metabolic abnormalities and other mechanism of sulfur compound affect cell function, protein synthesis and regulation, leading to the pathological changes of tissues and organs. Currently, there is no guideline for the diagnosis and treatment of demographic characteristics in China. This expert consensus is based on the review and analysis of research literature and evidence-based medicine at home and abroad in the past 30 years, combined with the characteristics of the Chinese population, recommending that tHcy ≥ 10μmol/L is defined as hyperhomocysteinemia. By adjusting the diet composition and / or using dietary supplements such as betaine, vitamins B and related coenzyme nutritional supplements, the level of tHcy can be prominently reduced, which is expected to significantly slow down the development of related diseases. It is recommended to carry out the detection indicators related to homocysteine, so as to clarify the causes of homocysteine rise, to guide the clinical precise intervention measures, effectively to improve the level of homocysteine, and to achieve the purpose of preventing the occurrence of diseases or delaying the progress of diseases.
