Chronic Renal Failure (CRF) is a debilitating condition which is responsible for high morbidity and mortality. Tissue injury due to free radicals is commonly seen in a variety of disease processes. The aim of the present study was to investigate the possible free radical mediated tissue damage in CRF before and after dialysis, by measuring Melondialdehyde (MDA) which is marker of oxidative stress. Antioxidants like Vitamin A, Vitamin E and Vitamin C, which prevent oxidative damage, were also measured. The study included 30 healthy persons as controls and 30 patients of CRF (before dialysis and after dialysis) as the study cases. All parameters were assessed by spectrophotometric methods.
Results: MDA levels were found to be significantly increased in pre dialysis CRF patients as compared to the controls (P< 0.001) and the levels further increased in post dialysis CRF patients as compared to that in pre dialysis CRF patients (P <0.001). The levels of antioxidants like Vitamin A, Vitamin E and Vitamin C were significantly decreased in pre dialysis patients as compared to the controls (P=<0.001) and the values further significantly decreased in post dialysis patients as compared to the pre dialysis CRF patients(P<0.001).
Conclusion: This study indicates that there is considerable oxidative stress in patients with CRF, which is further exacerbated by hemodialysis, as evidenced by increased lipid peroxidation and low antioxidant levels.
