<![CDATA[Diabetes mellitus is a disease characterized by hyperglycemia. Chronic hyperglycemia indiabetes mellitus can cause various complications, one of which is diabetic nephropathy,which affects the kidney. Chronic hyperglycemia causes an increase in free radicals and adecrease in antioxidant activity resulting in oxidative stress conditions. This study aims to determine kidney damage caused by oxidative stress and the role of antioxidants in reducingthis damage through literature studies. The literature used comes from Google search results such as PubMed, Google Scholar, ResearchGate, and ScienceDirect. From the search results, ten journals meeting the inclusion and exclusion criteria were selected for review and comparison so that a conclusion could be drawn. The results of this literature study have demonstrated that biochemical parameters, such as increased levels of creatinine, urea, malondialdehyde (MDA), and decreased antioxidant enzymes, as well as kidney histological parameters, such as changes in the shape of tubules, glomeruli, and increased kidney expression, are indicators of kidney damage caused by oxidative stress. The mechanism of antioxidants in reducing kidney damage is through DNA cutting, binding to phenolic OH groups, down-regulation of the oxidase expression of nitrogen oxides 4 nicotinamide adenine dinucleotide phosphate (Nox4 NADPH), antioxidant enzyme systems, activation of the activated protein kinase pathway - silent mating type information regulation 2 homolog 1- peroxisome proliferator-activated receptor-γ coactivator 1α (AMPK-SirT1- PGC-1 α), protein glycation reactions, and inhibition of protein 53 (P53) so that erythroid nuclear factor 2-related factor 2 (Nrf2) can activate antioxidant gene transcription.
