Purpose

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.

Ketogenic Diet
The KD will follow general principles the investigators have described with the aim to achieve blood ketones >0.5 mM, which will require most participants to consume <50 g/day carbohydrate and ~1.5 g/kg reference weight protein. Fat will comprise the remaining calories with an emphasis on monounsaturated and saturated sources from whole foods.
  • Other: Ketogenic Diet
    The diet intervention will start after all baseline testing is complete
  • Biological: Ketone/Glucose Monitoring
    KetoMojo hand-held glucometer will be used daily to monitor dietary intervention adherence.
  • Biological: CGM/CKM
    Continuous Ketone/Glucose Monitor will be applied at the start of Test Day 1. The sensor will be checked by the study team at each test day and will be removed and replaced by a fresh sensor at ~2- week intervals during the study. The sensor will be removed at the end of the final test day.
  • Biological: Blood Draw
    Blood samples will be collected according to the schedule in Figure 1
  • Other: Body Composition
    DEXA Scanning will be done pre-, mid-, and post- intervention.
  • Other: Change in glomerular filtration rate (mg/mmol) via magnetic resonance imaging (MRI) .
    Changes in glomerular filtration rate will be assessed via magnetic resonance imagining conducted by trained professionals. MRI imaging analyses will determine cardiac function. Trained imaging professionals will analyze the images to determine overall change (mg/mmol).
