Exploring a Complex Interplay: Kidney-Gut Axis in Pediatric Chronic Kidney Disease

Area of Science:

• Microbiology
• Pediatric Nephrology
• Gastroenterology

Background:

• The human intestinal microbiota plays a vital role in health, influencing digestion, nutrient synthesis, and immunity.
• Gut microbial composition is affected by diet, genetics, and environment, and is particularly dynamic in children.
• Chronic kidney disease (CKD) in individuals is often associated with significant gut microbiota disturbances.

Purpose of the Study:

• To review the current understanding of the gut-kidney axis in pediatric patients.
• To explore how gut dysbiosis impacts the development and progression of chronic kidney disease in children.
• To summarize available pharmaceutical and non-pharmaceutical treatment strategies for this condition.

Main Methods:

• Literature review of existing research on the gut-kidney axis in pediatric chronic kidney disease.
• Analysis of factors contributing to gut dysbiosis in CKD patients, including toxin accumulation, inflammation, and oxidative stress.
• Synthesis of information on therapeutic interventions targeting the gut microbiome.

Main Results:

• A significant disturbance in the gut microbiota is frequently observed in pediatric patients with chronic kidney disease.
• This gut dysbiosis contributes to CKD progression through mechanisms like increased circulating uremic toxins and systemic inflammation.
• The review identifies various treatment approaches, highlighting the potential of targeting the gut microbiome.

Conclusions:

• The gut-kidney axis is a critical factor in pediatric chronic kidney disease.
• Addressing gut dysbiosis presents a promising therapeutic avenue for managing CKD in children.
• Further research is needed to optimize interventions for the pediatric population.
