Traditional and novel dietary interventions for preventing progression of chronic kidney disease

Area of Science:

• Nephrology
• Gastroenterology

Background:

• Chronic kidney disease (CKD) treatment remains a significant challenge, with current therapies like blood pressure control and renin-angiotensin system inhibitors only slowing, not halting, disease progression.
• Dietary protein restriction can slow CKD but faces challenges with patient adherence and potential adverse effects like protein-energy wasting (PEW).

Purpose of the Study:

• To review interventions that prevent the absorption of protein catabolic products from the gut as an alternative strategy for managing CKD.
• To highlight recent advancements in this therapeutic area for slowing or preventing CKD progression.

Main Methods:

• Review of existing literature on interventions targeting the gut to reduce uremic toxin accumulation.
• Focus on medications designed to inhibit the absorption of protein breakdown products.

Main Results:

• Current CKD treatments have limitations in halting or reversing disease progression.
• Dietary protein restriction is effective but difficult to implement due to adherence and side effect concerns.
• Gut-targeted interventions offer a promising alternative to mitigate uremic waste accumulation.

Conclusions:

• Preventing the absorption of protein catabolic products from the gut is a viable strategy to complement or replace traditional CKD therapies.
• Further research and development in this area could lead to novel treatments for CKD and its complications.
