Oxidative stress - chronic kidney disease - cardiovascular disease: A vicious circle

Area of Science:

• Nephrology
• Cardiology
• Pathophysiology

Background:

• Cardiovascular disease (CVD) is a leading cause of mortality in patients with chronic kidney disease (CKD).
• Traditional cardiovascular risk factors do not fully explain the high incidence of CVD in CKD.
• Endothelial dysfunction, inflammation, and oxidative stress are implicated in both CKD and CVD.

Purpose of the Study:

• To review the interconnections between oxidative stress, inflammation, and endothelial dysfunction in CKD and CVD.
• To explore the "vicious circle" where these factors exacerbate each other.
• To identify potential therapeutic targets for mitigating CVD in CKD patients.

Main Methods:

• Literature review focusing on the interplay of oxidative stress, inflammation, and endothelial dysfunction.
• Analysis of mechanisms underlying these interconnections in CKD and CVD.
• Synthesis of current understanding and identification of research gaps.

Main Results:

• Oxidative stress, inflammation, and endothelial dysfunction are interconnected in a self-perpetuating cycle.
• This cycle significantly contributes to the high cardiovascular morbidity and mortality observed in CKD patients.
• Understanding these interconnections is crucial for developing effective interventions.

Conclusions:

• The "vicious circle" of oxidative stress, inflammation, and endothelial dysfunction is a key driver of CVD in CKD.
• Targeting these interconnected pathways offers potential for novel therapeutic strategies.
• Further research is needed to elucidate specific mechanisms and optimize interventions.
