Correlation of serum albumin and creatinine with oxidative stress markers in patients having nephrotic syndrome

Objective: Children with nephrotic syndrome (NS) have a stressful condition, and oxidative damage may impair their treatment response. This study aims to gain a better understanding of the relationship between oxidative stress and NS to lay the basis for further research into improved diagnostic options, treatment, and prevention of the disease. Methods: We took a blood sample from 100 Indian patients aged 2-14 y. Each patient was tested for oxidative stress. The buege method was used to assess MDA levels in patients. The pyrogallol method was used to measure SOD activity in blood serum, and the jollow method was used to measure glutathione levels. Results: The levels of oxidative stress markers (MDA, SOD, and GSH) were compared between NS patients and the control. SOD and GSH concentrations were significantly decreased in the NS group when compared to the control. In contrast, MDA level was significantly higher in the NS group than in the control. In the correlation analysis, we found that the serum SOD activity was significantly positively correlated with serum albumin and creatinine level in patients with NS. Thus, oxidative stress in children with NS is indicated by reduced antioxidant potential because of low albumin. Therefore, it is thought that oxidative stress is implicated in the development of NS in Indian children. Conclusion: We concluded that oxidative stress was intensified in children with NS due to decreased antioxidant levels caused by hypoalbuminemia.
