Abstract:
Acute kidney injury and chronic kidney disease are among the most common non-communicable diseases in the developed world, with increasing prevalence. Patients with acute kidney injury are at an increased risk of developing chronic kidney disease. One of kidney injury's most common clinical sequelae is increased cardiovascular morbidity and mortality. In recent years, new insights into the pathophysiology of renal damage have been made. Oxidative stress is the imbalance favoring the increased generation of ROS and/or reduced body's innate antioxidant defense mechanisms and is of pivotal importance, not only in the development and progression of kidney disease but also in understanding the enhanced cardiovascular risk in these patients. This article summarizes and emphasizes the role of oxidative stress in acute kidney injury, various forms of chronic kidney disease, and also in patients on renal replacement therapy (hemodialysis, peritoneal dialysis, and after kidney transplant). Additionally, the role of oxidative stress in the development of drug-related nephrotoxicity and also in the development after exposure to various environmental and occupational pollutants is presented.
Insights
Oxidative stress plays a key role in kidney disease development and progression. Understanding its impact is crucial for managing kidney disease and associated cardiovascular risks in patients undergoing renal replacement therapy.
Area of Science:
- Nephrology
- Cardiovascular Medicine
- Biochemistry
Background:
- Acute kidney injury (AKI) and chronic kidney disease (CKD) are prevalent non-communicable diseases.
- AKI patients face a higher risk of developing CKD and increased cardiovascular morbidity/mortality.
- Oxidative stress, an imbalance in reactive oxygen species (ROS) and antioxidant defenses, is increasingly recognized in renal pathophysiology.
Purpose of the Study:
- To summarize and emphasize the critical role of oxidative stress in kidney diseases.
- To explore the link between oxidative stress and enhanced cardiovascular risk in kidney patients.
- To present the involvement of oxidative stress in drug-induced nephrotoxicity and environmental pollutant exposure.
Main Methods:
- Review of current literature on oxidative stress and kidney disease.
- Analysis of the pathophysiology of renal damage and cardiovascular complications.
- Examination of oxidative stress in various stages of kidney disease and renal replacement therapy.
Main Results:
- Oxidative stress is pivotal in the development and progression of AKI and CKD.
- It significantly contributes to the increased cardiovascular risk observed in kidney disease patients.
- Oxidative stress is implicated in nephrotoxicity from drugs and environmental pollutants.
Conclusions:
- Oxidative stress is a central mechanism in kidney injury and disease.
- Targeting oxidative stress may offer therapeutic strategies for kidney disease and cardiovascular complications.
- Further research into oxidative stress is essential for managing kidney health and related conditions.
