Study on serum level of homocysteic acid in patients with type 2 diabetic mellitus / 国际检验医学杂志

ABSTRACT

Objective To study the relationship between serum level of homocysteic acid(Hcy)and type 2 diabetic mellitus(T2DM),and to explore the influencing factors serum for Hey level in T2DM patients.Methods Totally T2DM 122 patients(T2DM group),67 patients with chronic kidney diease(CKD group)and 50 healthy controls(CON group)were enrolled in the investigation.The variation of serum Hcy of all groups was observed,and the correlation of serum Hcy level with estimated glomerular filtration rate(eGFR),fasting serum glucose,HbA1C,Urea and creatinine was analyzed.Serum Hcy was measured by enzymatic cycling assay;HbA1C was measured by high-pressure liquid chromatography assay;and eGFR was calculated by using the Levey-modified Modification of Diet in Renal Disease formula.Results There was no significant difference in serum level of Hcy between T2DM group and CON group(P＞0.05).The serum concentration of Hey was significantly higher in CKD group than that of T2DM group and CON group(P＜0.01).There was only 8.20% exceeding the upper limit of 95% of CON group in T2DM group,while 64.18% exceeding the upper limit of 95% of CON group in CKD group.There was no significant difference of Hcy level between patients with eGFR≥90 mL·(min·1.73 m2)-1 in T2DM group and healthy controls(P＞0.05),but the Hey level was significantly higher in patients with eGFR＜90 mL·(min·1.73 m2)-1 than that of healthy controls(P＜0.05).In T2DM group and CKD group,serum Hey level was negatively correlative to eGFR(P＜0.01).positively correlative to Urea and creatinine(P＜0.01);but serum Hcy level did not correlate with fasting serum glucose,HbA1C,total cholesterol and triglyceride(P＞0.05).Conclusion Renal function is an independent risk factor for serum homocysteine level in type 2 diabetes rather than diabetes itself.
