About 30-40% of diabetic patients who developed nephropathy have lipoprotein disorders, especially lipoprotein a [Lp(a)], which is related to atherosclerosis.
The aim of this study was to investigate the effect of N-acetyl cysteine (NAC) on the serum levels of Lp(a) and amount of proteinuria in a group of type 2 diabetic patients with diabetic nephropathy.
A total of 40, type 2 diabetic (T2D) patients, patients with proteinuria, were randomly divided into two groups. The experimental group was treated by NAC (1200 mg/day) for two months in conjunction with conventional treatment for diabetes and hypertension. Control group received routine medications.
No significant change was identified in serum Lp(a) during treatment with NAC (P >0.05). However, NAC decreased the amount of proteinuria, serum triglyceride (TG) level and systolic blood pressure in experimental group compared to the control group (P <0.05).
These findings suggest that treatment with NAC has no significant effect on the serum level of Lp (a). However, it has beneficial effects on the reduction of proteinuria, serum TG level and systolic blood pressure in T2D patients with nephropathy. Further prospective studies are needed to determine its full role.
在发生肾病的糖尿病患者中,约30%-40%存在脂蛋白紊乱,尤其是脂蛋白a[Lp(a)],其与动脉粥样硬化有关。
本研究旨在探讨N-乙酰半胱氨酸(NAC)对一组2型糖尿病肾病患者血清Lp(a)水平及蛋白尿含量的影响。
共有40例有蛋白尿的2型糖尿病(T2D)患者被随机分为两组。实验组在接受糖尿病和高血压常规治疗的同时,接受NAC(1200毫克/天)治疗两个月。对照组接受常规药物治疗。
在使用NAC治疗期间,血清Lp(a)无显著变化(P>0.05)。然而,与对照组相比,实验组的NAC降低了蛋白尿含量、血清甘油三酯(TG)水平和收缩压(P<0.05)。
这些发现表明,NAC治疗对血清Lp(a)水平无显著影响。然而,它对降低2型糖尿病肾病患者蛋白尿、血清TG水平和收缩压有有益作用。需要进一步的前瞻性研究来确定其全部作用。
