- Original description
This is a prospective study to determine ketogenic diet effect on htTKV, GFR, microalbuminuria. This is a single-center study of 20 patients with ADPKD and deemed high risk for progression to ESRD. This determined by combination of features of ADPKD and htTKV as assessed by prior computed tomography (CT) or MRI. Patients will be recruited from the Polycystic Kidney Disease (PKD) Clinic at Ohio State University Wexner Medical Center. Enrolled patients will have MRI for htTKV, urinary studies, blood tests at baseline, 6 months, and 52 weeks. Blood for GFR will be assessed three times over the course of the study including baseline, 6 months, and 1 year. Participants will follow ketogenic diet for 52 weeks. Investigatory diet team will manage the ketogenic diet.Read full original descriptionShow less
Feasibility and Efficacy of a Well-Formulated Ketogenic Diet in Delaying Progression of Polycystic Kidney Disease in Patients at Risk for Rapid Progression
This is a prospective study to determine ketogenic diet effect on htTKV, GFR, microalbuminuria. This is a single-center study of 20 patients with ADPKD and deemed high risk for progression to ESRD. This determined by combination of features of ADPKD and htTKV as assessed by prior computed tomography (CT) or MRI. Patients will be recruited from the Polycystic Kidney Disease (PKD) Clinic at Ohio State University Wexner Medical Center. Enrolled patients will have MRI for htTKV, urinary studies, blood tests at baseline, 6 months, and 52 weeks. Blood for GFR will be assessed three times over the course of the study including baseline, 6 months, and 1 year. Participants will follow ketogenic diet for 52 weeks. Investigatory diet team will manage the ketogenic diet.

Exclusion: Patients currently being treated with Tolvaptan; Chronic alcohol or drug abuse; Diagnosed with diabetes; Gastrointestinal disorders that will interfere with diet intervention; Severe kidney disease with GFR < 25 mg/dl; Pregnancy; Contraindications to MRI; Ketogenic diet within the last three months; Unable to purchase food for the diet intervention.
