ABSTRACT
In continuation of our work on human stress situation and present day awareness of the role of free radical toxicity in a variety of clinical conditions, oxidative stress status (in terms of serum levels of MDA, scavenging enzyme SOD, vitamins: C and E) has been studied in 45 pediatric patients with nephrotic syndrome (further classified as steroid: responders, frequent/ infrequent relapsers, dependents). The results have been compared with 42 appropriately age healthy children as controls. The salient features of the present study centre around typical observations viz significantly increased levels of MDA (7.92 +/- 2.24 nmol/ml), decreased levels of SOD (1.36 +/- 1.01 U/ml), vitamin C (0.49 +/- 0.17 mg/dl) and vitamin E (0.52 +/- 0.19 mg/dl) in children with nephrotic syndrome as a whole when compared with healthy controls [MDA (4.40 +/- 1.31 nmol/ml), SOD (3.04 +/- 1.83 U/ml), vitamin C (0.60 +/- 0.26 mg/dl) and vitamin E (0.68 +/- 0.25 mg/dl) respectively]. An almost similar trend was encountered in different groups as classified. However, maximum fluctuations were observed in steroid dependents. The present observations appear to be suggestive of alternative guidelines to clinicians in the absence of conventional renal biopsy as the procedure. It is felt that children with nephrotic syndrome should regularly take vitamins C and E from the health point of view.
