NCT03494010

Brief Summary

The investigators' primary aim is to determine the impact of using hybrid closed-loop (HCL) system in patients with type 1 diabetes (T1D) and end stage renal disease (ESRD) prior to kidney transplantation. The investigators will also determine whether HCL, by improving glucose control, will affect short-term (1 month) and long-term (12 months) complications after kidney transplantation in patients with T1D.

Outcome Measures

Primary Outcomes (1)

  • Duration of use of hybrid closed-loop (HCL) system

    Use will be measured in weeks

    up to 1 year post-surgery

Secondary Outcomes (11)

  • Kidney transplantation outcome - graft rejection

    Up to 3 months post-transplant

  • Kidney transplantation outcome - infections

    Up to 3 months post-transplant

  • Kidney transplantation outcome - mortality

    3 years from study enrollment

  • hyperglycemia: glucose levels > 180 milligrams per deciliter (mg/dL)

    change from baseline to 1 month after surgery

  • hyperglycemia: glucose levels > 180 mg/dL

    change from baseline to 1 year after surgery

  • +6 more secondary outcomes

Study Arms (2)

prospective cohort

Patients will be followed to determine the impact of the hybrid closed-loop (HCL) system that was prescribed at part of clinical care.

Other: Observation

historical controls

Medical record data of these patients, who did not use the HCL system, will be compared with patients in the HCL cohort.

Interventions

There is no intervention. Patients will receive the HCL system as part of their clinical care.

prospective cohort
