Ten‐year outcomes of islet transplantation in patients with type 1 diabetes: Data from the Swiss‐French GRAGIL network

To describe the 10‐year outcomes of islet transplantation within the Swiss‐French GRAGIL Network, in patients with type 1 diabetes experiencing high glucose variability associated with severe hypoglycemia and/or with functional kidney graft. We conducted a retrospective analysis of all subjects transplanted in the GRAGIL‐1c and GARGIL‐2 islet transplantation trials and analyzed components of metabolic control, graft function and safety outcomes over the 10‐year period of follow‐up. Forty‐four patients were included between September 2003 and April 2010. Thirty‐one patients completed a 10‐year follow‐up. Ten years after islet transplantation, median HbA1c was 7.2% (6.2–8.0) (55 mmol/mol [44–64]) versus 8.0% (7.1–9.1) (64 mmol/mol [54–76]) before transplantation (p
