Insulin independence following islet transplantation improves long‐term metabolic outcomes

Diabet MedPublished Retrospective cohort study

Authors' conclusion

This is the largest UK single-centre study on islet transplant to date. Our findings demonstrate significantly improved outcomes in patients who achieved insulin independence following islet transplantation.

Study context

Population
Patients with T1D who underwent islet transplantation in Scotland up to 31 January 2020; 74.5% had >50 severe hypoglycaemic episodes in the year before transplant
Participants
60 patients
Exposure
Insulin independence at any point after islet transplantation vs no insulin independence
Outcome
Graft survival (stimulated C-peptide >50 pmol/L)
Methodological detailsdata collected prospectively, single-centre
  • Data collected prospectively
  • Single-centre
