Targeting Uremic Toxins to Prevent Peripheral Vascular Complications in Chronic Kidney Disease

Area of Science:

• Nephrology
• Vascular Biology
• Toxicology

Background:

• Chronic kidney disease (CKD) disrupts homeostasis, leading to uremic toxin accumulation, renin-angiotensin system activation, oxidative stress, and inflammation.
• CKD patients have a higher incidence of peripheral vascular disease (PVD), resulting in worse clinical outcomes.
• The interplay between the uremic environment and PVD exacerbates vascular complications like limb ischemia, amputation, and thrombosis, increasing mortality.

Purpose of the Study:

• To review the role of uremic toxins in the pathophysiology of vascular dysfunction in CKD.
• To explore the potential of uremic toxins as therapeutic targets for PVD in CKD patients.
• To summarize current clinical approaches for reducing uremic toxins to prevent PVD complications in CKD.

Main Methods:

• Literature review focusing on the pathophysiology of uremic toxins and PVD in CKD.
• Analysis of in vitro and animal models investigating uremic toxin effects on vascular health.
• Examination of current and novel clinical strategies for managing uremic toxins in CKD.

Main Results:

• Uremic toxins significantly contribute to vascular dysfunction and complications in CKD.
• Evidence supports targeting uremic toxins as a therapeutic strategy for PVD in CKD.
• Various approaches are being explored to reduce uremic toxin burden and mitigate vascular risks.

Conclusions:

• Uremic toxins are key mediators of vascular complications in CKD-associated PVD.
• Therapeutic strategies aimed at reducing uremic toxins hold promise for improving outcomes in CKD patients with PVD.
• Further research into novel clinical approaches is crucial for effective prevention and management.
