Oxidative Stress with Homocysteine, Lipoprotein (a) and Lipid Profile in Diabetic Nephropathy

Diabetic nephropathy is the single most common disorder leading to renal diseases. Reactive oxygen species (ROS) play a major role in the development of diabetic nephropathy. Nephrotic syndrome is often manifesting in progression of diabetic nephropathy. Therefore, this study was carried out to investigate oxidant and antioxidant status in diabetic nephropathy patients. The blood samples were analyzed for quantitation of malondialdehyde as index of lipid peroxide, vitamin C, total antioxidant capacity, homocysteine, lipoprotein (a) and lipid profile. Significantly increased levels of serum total cholesterol, triglycerides, low density lipoprotein, malondialdehyde as index of lipid peroxide, lipoprotein (a), homocysteine (p<0.001) and decreased levels of serum total antioxidant capacity, total protein, albumin, high density lipoprotein & plasma vitamin C (p<0.001) were noticed in the patients with diabetic nephropathy as compared to control subjects.
