Who could benefit from this research

Could help

Patients with Autosomal Dominant Polycystic Kidney Disease (ADPKD), especially those who also experience kidney stones, are the focus of this research.

Less likely to help

Patients without ADPKD or kidney stone disease would likely not directly benefit from this specific research.

What this research studies

This research focuses on Autosomal Dominant Polycystic Kidney Disease (ADPKD), a condition affecting many people in the US. We know that kidney stones are common in ADPKD and may lead to faster kidney function decline. Our team will combine advanced data analysis with studies of gut bacteria (microbiome) and metabolism to understand this connection. We also want to see if antibiotic use increases the risk of kidney stones in this patient group and how imbalances in gut bacteria contribute to stone formation. This work aims to uncover new ways to protect kidney health for those with ADPKD.

Why it matters

Potential benefit: If successful, this work could identify new ways to slow kidney disease progression in ADPKD patients by better managing kidney stones and understanding the role of antibiotics and gut health.

How similar studies have gone: This proposal builds on preliminary data showing a link between kidney stones and faster kidney function loss in ADPKD, suggesting some prior foundational work.
