CORRELATION BETWEEN OXIDATIVE STRESS AND ANTIOXIDANT IN DIABETIC NEPHROPATHY
Background: Diabetic Nephropathy is consider as one of the major micro-vascular problems of diabetes mellitus and has become the most general single factor of end stage of kidney disease. It is defined traditionally by kidney morphological and modification like: glomerular hyper filtration, glomerular and kidney hypertrophy, increased urinary albumin excretion (> 300 mg/24 hours), increased GBM (Glomerular Basement Membrane) thickness and mesangial expansion and also accumulation of extracellular proteins comprising laminin, collagens and fibronectin worldwide. Oxidative stress (OS) has been characterized as the imbalance between reactive oxygen species (ROS) yielding and the possessive antioxidant defense system.
Objective of the study: Correlation between oxidative stress and antioxidant in diabetic nephropathy.
Materials and methods: The investigation was conducted on 100 DN subjects of both sex and aged 20 or more and 100 age and sex matched healthy control subjects. MDA, SOD and Catalase of each subject was measured.
Results: the present investigation shows that the MDA was elevated significantly and SOD and Catalase level was found to be significantly low in DN individuals as compared to controls. Conclusion: This study concluded that the MDA could be better marker for early recognition of DN.
