Brief Summary

Diabetes control is often assessed by tests of glucose levels over time, such as the glycosylated hemoglobin A1c (HbA1c) and fructosamine. In the later stages of chronic kidney disease (CKD) there is limited data available on the utility of these tests. There are reasons to believe that the tests may be less accurate in this population. Continuous glucose monitoring (CGM) offers an effective method for understanding the totality of glucose exposure and incidence of both hyperglycemic and hypoglycemic excursions.

Outcome Measures

Primary Outcomes (5)

  • Mean Glucose Concentration Measured by CGM

    Mean glucose concentration (mg/dL) will be measured using measurements taken by CGM device.

    14 Days

  • Number of Participants With Hypoglycemic Events

    Hypoglycemic event will be considered when blood sugar level is \<=70 mg/dl. Detail information like time of event, number of subjects with an event, duration of event will be analyzed.

    14 Days

  • Mean Number of Hypoglycemic Events Per Participant.

    Total number of hypoglycemic events per subject will be calculated during the study period. Mean number of events per subject will be analyzed.

    14 Days

  • Duration Hypoglycemic Events

    As monitoring device measures blood glucose level numerous time, duration of hypoglycemic event will be calculated in percent time per subject based on total duration of time subject wore CGM device.

    14 Days

  • Mean HbA1c

    HbA1c collected at end of the participation.

    14 Days

Secondary Outcomes (2)

  • Mean Serum Fructosamine Concentration

    14 Days

  • Determination of Serum Fructosamine

    14 days

Study Arms (1)

Continuous glucose monitoring

EXPERIMENTAL

* If subjects meet inclusion criteria then they will return to the research site on Day 1 to place Freestyle Libre Pro device by the research staff for 14-day monitoring. * Subjects will be advised to return to the research site on Day 14 to remove the CGM device for analysis. On Day 14, blood will be drawn for HbA1c and fructosamine, The blood drawn for this research will be approximately 10-15 milliliters. * There are no drug washout periods. Subjects will continue to take all their medications and/or insulins as prescribed by their doctor. * Baseline data including age, race, ethnicity, past medical history, home medication list, and diabetes related laboratory data will be collected.

Device: Continuous Glucose Monitoring

Interventions

* The FreeStyle Libre Pro Flash Glucose Monitoring System is a professional continuous glucose monitoring (CGM) device indicated for detecting trends and tracking patterns in persons (age 18 and older) with diabetes. The Freestyle Libre Pro device is FDA approved (PMA# P150021). Participants will use the FreeStyle Libre Pro Flash Glucose Monitoring device according to its approved use, on the back of the arm. * CGM monitoring will be performed on Day 1 by placing the Freestyle Libre Pro on research subjects for intended use of 14 days. * Subjects will be advised to return to the research site on Day 14 to remove the CGM device for analysis.

Limitations and Caveats

The sample size of 80 patients were predominately male and non-Hispanic. It would also have been meaningful to have more robust data of a diary of self-reported symptoms during the 14 day period.
