    Abstract:
    It has been proposed that nephrotic syndrome is a consequence of an imbalance between oxidant/antioxidant statuses. The present study aimed to assess oxidant and antioxidant status in relation to dyslipidemia in children during remission and relapse phases of steroid sensitive nephrotic syndrome (SSNS). The study dealt with 40 children diagnosed as SSNS. They were categorized into two subgroups. The first subgroup included 25 children during remission stage. The second subgroup included 15 children during relapse. Control group consisted of age and gender-matched 15 healthy children. Significantly higher serum levels of malondialdehyde, oxidized LDL, total cholesterol, LDL cholesterol, triglycerides, apolipoprotein A-I, and apolipoprotein-B were observed in patients with SSNS especially in the relapsers. The serum levels of albumin, glutathione peroxidase activity, vitamin C, A, and E, and HDL cholesterol were significantly lower in patients especially among relapsers. In conclusion, a strong relationship between the oxidant/antioxidant status and dyslipidemia is documented in patients with SSNS, especially among relapsers. No normalization of the biochemical indices was observed despite the use of glucocorticoids. Therefore, the combined use of steroid, antioxidant therapy, and lipid lowering therapy can be recommended in such children.
