About
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.
Full description
The investigators plan to recruit up to 25 patients with type 1 diabetes (T1D) being evaluated for a living donor kidney transplantation. These patients will be followed up to 1 year after the surgery. Participants will be recruited from the Yale Transplantation Center. Patients with end stage renal disease (ESRD) and T1D referred to the pre-transplantation clinic who have a living kidney donor and who are being considered candidates for a hybrid closed-loop (HCL) system as part of routine care, will be asked to participate in this study. Patients who show interest in the HCL system are already being referred to the Yale Transplant-Endocrine Clinic and/or the Yale Diabetes Center to be evaluated for feasibility of using the HCL. Patients will also be approached about the study, once prescribed the HCL 670G system, to be used until the surgery, as standard of care (SOC).
The HCL system will be prescribed as part of a standard care for patients with T1D willing to optimize their glucose control prior to surgery. The HCL system will not be provided by the research investigators. Also as part of SOC, Medtronic® will provide initial training (1st month) and technical support for the patients. Plan for routine care use: The HCL system will be removed during the hospital admission for the transplantation surgery and restarted after hospital discharge. Participants will be followed at the Yale Diabetes Center (YDC) and/or the Yale Transplant-Endocrine Clinic (YTEC) for management of diabetes and management of HCL system.
Patients will be seen monthly prior to the kidney transplantation. After the surgery, they will come to the YDC/YTEC clinics monthly for the first 3 months and every 3 months afterwards.
Patient information to be collected as part of the study:
The results from this cohort of patients with T1D treated with the HCL undergoing kidney transplantation will be compared to a retrospective cohort of up to 25 patients. This control cohort will be identified through a Joint Data Analytics Team (JDAT) query of patients followed at the Yale Transplant Center aged between 18-65 year, with T1D and who had received a living donor kidney transplantation in the last 3 years prior to the start date of this protocol. Medical records from these patients will be reviewed by the PI and/or co-investigators. Pertinent demographic and medical information will be recorded, as described above for the HCL treated group.
