Obesity and Oxalate Production in Kidney Stones
N/A
Waitlist Available
Led By Kyle D Wood, MD
Research Sponsored by University of Alabama at Birmingham
Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial Must have
Calcium oxalate stone formers with passage or removal of a kidney stone containing > 50% calcium oxalate
Type 2 Diabetics with fasting glucose > 126 mg/dL or hemoglobin A1c greater than or equal to 6.5%
Must not have
A glomerular filtration rate (GFR) or estimated GFR < 60 mls/min
Any disease that will affect the urinary excretion of oxalate, calcium or another ion that will compromise the interpretation of results
Timeline
Screening 3 weeks
Treatment Varies
Follow Up 3 days on fixed diet
Awards & highlights
No Placebo-Only Group
Summary
This trial will study how obesity affects the amount of oxalate in urine, which contributes to calcium oxalate kidney stones.
Who is the study for?
This trial is for adults with a BMI under 30 who have had kidney stones made mostly of calcium oxalate, and those with Type 2 Diabetes showing specific blood sugar levels. It's not for pregnant individuals, people with abnormal urine or blood tests that could affect the study results, anyone with poor kidney function (GFR < 60), or a BMI over 32.
What is being tested?
The study aims to understand how obesity affects urinary oxalate levels and the formation of calcium oxalate kidney stones. It will explore this link in different groups: non-obese individuals, obese stone formers, and diabetics.
What are the potential side effects?
Since this trial seems observational rather than interventional—meaning it observes participants without administering treatments—there are no direct side effects from medications or procedures listed.
