BACKGROUND: Chronic kidney disease (CKD) represents a state of persistent, sterile low-grade inflammation in which sustained innate immune activation accelerates renal decline and cardiovascular complications. Diet-induced gut dysbiosis and intestinal barrier dysfunction lower mucosal immune tolerance, promote metabolic endotoxemia, and position the gut as an upstream modulator of systemic inflammatory signaling along the gut-kidney axis.
SCOPE: Most studies address microbiota-derived metabolites, food-derived bioactive peptides, or omega-3 fatty acids separately. This review integrates evidence across these domains and examines their convergent actions on epithelial barrier integrity, immune polarization, oxidative-inflammatory stress, and inflammasome-dependent pathways relevant to CKD progression. Key mechanisms: CKD-associated dysbiosis is characterized by reduced short-chain fatty acid (SCFA) production and increased generation and accumulation of uremic toxins and co-metabolites, including indoxyl sulfate, p-cresyl sulfate, trimethylamine N-oxide, and altered bile acids. Reduced SCFA availability weakens tight junction-dependent barrier function and regulatory immune programs, favoring Th17-skewed inflammation and endotoxin translocation. Bioactive peptides modulate inflammatory mediator networks and barrier-related pathways through effects on NF-κB/MAPK signaling and redox balance, while omega-3 fatty acids and specialized pro-resolving mediators support resolution-phase immune responses. Across these modalities, shared control points include barrier integrity, metabolic endotoxemia, oxidative stress, and NLRP3 inflammasome activation.
CONCLUSIONS: Although evidence remains heterogeneous and largely preclinical, combined nutritional modulation targeting these convergent pathways may offer greater immunomodulatory benefit than isolated interventions. Future multi-omics-guided, factorial trials are required to define responder phenotypes and translate precision immunonutrition strategies into clinical CKD care.
