Summary

Autosomal dominant polycystic kidney disease (ADPKD) is characterized by progressive cyst growth and declining kidney function. Inflammatory pathways, including those mediated by monocyte chemoattractant protein-1 (MCP-1), are increasingly recognized as contributors to disease progression. Metabolic alterations in cystic epithelial cells may influence inflammatory signaling, suggesting a potential role for dietary interventions targeting metabolic pathways.

This study is a prospective, randomized, open-label crossover trial designed to evaluate the effect of a carbohydrate restricted, plant dominant dietary intervention on urinary MCP-1 levels in adults with ADPKD. Participants will be randomized to one of two sequences: dietary intervention followed by usual diet, or usual diet followed by dietary intervention, with a washout period between study phases. Each study period will last 12 weeks.

The primary objective is to assess within subject differences in urinary MCP-1/creatinine ratio between the dietary intervention and usual diet conditions. Secondary outcomes include measures of metabolic parameters, insulin resistance, dietary adherence, and safety.

This study aims to explore whether a structured dietary approach may influence intrarenal inflammatory activity in ADPKD and provide preliminary data to inform future interventional studies.

Conditions

  • Autosomal Dominant Polycystic Kidney Disease (ADPKD)

Interventions

BEHAVIORAL

Carbohydrate Restricted, Plant Dominant Diet

A structured dietary intervention targeting approximately 20% of total daily energy intake from carbohydrates (range 15-25%), with a plant dominant composition. Energy and protein intake are prescribed based on adjusted body weight. The intervention is not ketogenic and is not intended to induce nutritional ketosis. Participants receive individualized dietary counseling and ongoing support from a registered dietitian.

BEHAVIORAL

usual diet

Participants continue their habitual diet without specific dietary intervention or structured nutritional guidance.
