Abstract

BACKGROUND: Registry data on patients with type 1 diabetes mellitus who undergo pancreatic islet transplantation indicate that only 8 percent are free of the need for insulin therapy at one year. METHODS: Seven consecutive patients with type 1 diabetes and a history of severe hypoglycemia and metabolic instability underwent islet transplantation in conjunction with a glucocorticoid-free immunosuppressive regimen consisting of sirolimus, tacrolimus, and daclizumab. Islets were isolated by ductal perfusion with cold, purified collagenase, digested and purified in xenoprotein-free medium, and transplanted immediately by means of a percutaneous transhepatic portal embolization. RESULTS: All seven patients quickly attained sustained insulin independence after transplantation of a mean (+/-SD) islet mass of 11,547+/-1604 islet equivalents per kilogram of body weight (median follow-up, 11.9 months; range, 4.4 to 14.9). All recipients required islets from two donor pancreases, and one required a third transplant from two donors to achieve sustained insulin independence. The mean glycosylated hemoglobin values were normal after transplantation in all recipients. The mean amplitude of glycemic excursions (a measure of fluctuations in blood glucose concentrations) was significantly decreased after the attainment of insulin independence (from 198+/-32 mg per deciliter [11.1+/-1.8 mmol per liter] before transplantation to 119+/-37 mg per deciliter [6.7+/-2.1 mmol per liter] after the first transplantation and 51+/-30 mg per deciliter [2.8+/-1.7 mmol per liter] after the attainment of insulin independence; P<0.001). There were no further episodes of hypoglycemic coma. Complications were minor, and there were no significant increases in lipid concentrations during follow-up. CONCLUSIONS: Our observations in patients with type 1 diabetes indicate that islet transplantation can result in insulin independence with excellent metabolic control when glucocorticoid-free immunosuppression is combined with the infusion of an adequate islet mass.

  • Shapiro and colleagues' steroid-free Edmonton Protocol demonstrated that islet transplantation can produce insulin independence.

    “Shapiro and colleagues’ landmark work, by use of a steroid free Edmonton Protocol,160 showed that islet transplantation could achieve insulin independence”

    From Type 1 diabetes (2018) · cites this paper as [160]

  • In 2000, a breakthrough protocol was developed for islet transplantation without the use of glucocorticoids for immune suppression.

    “In 2000, a breakthrough protocol was developed for islet transplantation without the use of glucocorticoids for immune suppression;149”

    From Type 1 diabetes (2014) · cites this paper as [149]

  • Transplantation of pancreatic islets alone had limited success until the Edmonton Protocol in 2000 demonstrated that infusion of islets into the liver via the portal vein was sufficient to restore glucose homeostasis.

    “Transplantation of pancreatic islets alone to restore β cell mass, however, had limited success until the development of the Edmonton Protocol in 2000, which demonstrated that infusion of islets into the liver via the portal vein was sufficient to restore glucose homeostasis.15,16”
  • Graft success increases when a high number of islets are transplanted, often resulting in the need for multiple donor pancreases.

    “In particular, graft success increases when a high number of islets are transplanted, often resulting in the need for multiple donor pancreases. 15,20,24”
  • The Edmonton Protocol initial trial led to insulin independence of all seven patients 1 year after transplantation.

    “Their initial trial led to insulin independence of all seven patients 1 year after transplantation, vastly improving previous islet transplantation outcomes due to optimization of their immunosuppression regimen as well as benefiting from improvements in islet isolation techniques.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
