血清同型半胱氨酸、叶酸和维生素B_(12)浓度检测在非酒精性脂肪性肝病患者中的临床应用

目的:探讨血清同型半胱氨酸(Hcy)、叶酸和维生素B12浓度检测在非酒精脂肪性肝病(NAFLD)患者诊断中的临床意义。方法:根据CT检查结果将符合临床诊断标准的123例NAFLD患者分为轻度、中-重度脂肪肝组,以同期体检健康者139名作为对照组,测定血清Hcy、丙氨酸转氨酶(ALT)、天冬氨酸转氨酶(AST)、总胆固醇(TC)、三酰甘油(TG)、高密度脂蛋白(HDL)、低密度脂蛋白(LDL)、叶酸和维生素B12浓度,并进行Hcy与叶酸、维生素B12浓度的相关性分析。结果:中-重度NAFLD患者的Hcy、ALT、AST、TC、TG均明显高于轻度NAFLD组和健康对照组,HDL、维生素B12水平明显低于轻度NAFLD组和健康对照组(P<0.05)。轻度NAFLD组ALT、Hcy明显高于健康对照组,HDL明显低于健康对照组(P<0.05),并且血清Hcy与叶酸、维生素B12呈直线负相关。结论:NAFLD患者Hcy水平随着肝脏脂肪变性的加重而升高,高Hcy血症可能是NAFLD一个新的危险因素,提示Hcy在NAFLD发病中起一定作用。并且叶酸、维生素B12水平与Hcy水平具有相关性。

Determination of serum homocysteine,folate and vitamin B_(12) in patients with nonalcoholic fatty liver disease

Objective To investigate the clinical significance of serum homocysteine(Hcy),folate and vitamin B12 in nonalcoholic fatty liver disease(NAFLD).Method One hundred and twenty-three patients with nonalcoholic fatty liver disease were divided into mild NAFLD and moderate/severe NAFLD according to CT results,and 139 healthy subjects served as controls.Serum levels of Hcy,alanine transaminase(ALT),aspartate transaminase(AST),total cholesterol(TC),triglyceride(TG),high density lipoprotein(HDL),low density lipopro...
