Abstract:
Drug-induced kidney injury remains a major clinical challenge associated with diverse therapeutic agents and is an important cause of acute kidney injury, chronic renal dysfunction, and treatment-related morbidity. Growing evidence indicates that nephrotoxicity caused by anticancer, immunosuppressive, and anti-infective drugs is strongly driven by oxidative stress and redox homeostasis disruption. Excessive production of reactive oxygen species (ROS) in renal tubular cells overwhelms endogenous antioxidant defenses and triggers mitochondrial dysfunction, inflammatory signaling, and activation of stress-responsive pathways that culminate in tubular injury and renal functional decline. These processes promote apoptosis, necrosis, microvascular injury, and a reduction in the glomerular filtration rate, while dysregulation of redox-sensitive pathways involved in cell survival and repair further heightens renal vulnerability. This review summarizes current mechanistic insights into oxidative stress-mediated pathways of drug-induced nephrotoxicity, with emphasis on their translational relevance. In addition, it discusses emerging biomarkers for early detection and highlights recent advances in antioxidant-based and redox-modulating strategies that may help prevent renal injury and preserve kidney function.
Insights
Drug-induced kidney injury is often caused by oxidative stress disrupting cellular balance. This review explores how reactive oxygen species (ROS) damage kidneys and discusses new antioxidant strategies for prevention.
Area of Science:
- Nephrology
- Toxicology
- Biochemistry
Background:
- Drug-induced kidney injury (DIKI) is a significant clinical issue linked to various medications.
- Nephrotoxicity from anticancer, immunosuppressive, and anti-infective drugs is increasingly attributed to oxidative stress.
- Disruption of redox homeostasis in renal tubular cells leads to cellular damage and functional decline.
Purpose of the Study:
- To review the mechanisms of oxidative stress in drug-induced nephrotoxicity.
- To highlight the translational relevance of these mechanisms.
- To discuss emerging biomarkers and antioxidant strategies for kidney protection.
Main Methods:
- Literature review of mechanistic insights into drug-induced nephrotoxicity.
- Focus on oxidative stress and redox homeostasis disruption pathways.
- Examination of current and emerging therapeutic strategies.
Main Results:
- Excessive reactive oxygen species (ROS) production overwhelms antioxidant defenses, causing mitochondrial dysfunction and inflammation.
- Oxidative stress triggers apoptosis, necrosis, microvascular injury, and reduced glomerular filtration rate.
- Dysregulation of redox-sensitive pathways exacerbates renal vulnerability.
Conclusions:
- Oxidative stress is a key mediator of DIKI, involving complex cellular signaling pathways.
- Early detection biomarkers and novel antioxidant/redox-modulating therapies hold promise for preventing kidney injury.
- Understanding these mechanisms is crucial for preserving kidney function during drug therapy.
