Descrizione

Inclusion Criteria:

  • Patient with type 1 diabetes or C-peptide negative diabetes Diabetes duration > 5 years
  • No residual insulin secretion (plasmatic basal and stimulated C-peptide < 0.3 ng/ml)
  • HbA1c considered acceptable by the selection committee
  • Insulin needs < 0.85 IU/kg/day
  • Islet cell infusion after kidney graft

    • Patient with terminal renal failure and functional kidney graft for at least 6 months (creatinine clearance greater than or equal to 35 ml/min)
    • Patient whose glycaemic control obtained with insulin therapy could threaten kidney graft survival and/or significantly alter quality of life. This situation is assessed by a diabetologist
  • Islet cell infusion only: patient with major glycaemic variability despite proper intensive insulin therapy, closely monitored by a diabetologist. Poor glucose control, assessed by a diabetologist, endangers the patient's life and/or significantly alters personal, social, professional and family quality of life. At least one of these criteria must be fulfilled :

    • Hypoglycaemia unawareness, blood glucose level < 3mmol/L or 0.54 mg/L
    • At least 2 severe hypoglycaemia events (defined by the necessity of a third party's assistance) per year or a ketoacidosis requiring patient's hospitalization during the last year.
    • Impairment of quality of life or life-threat for patient or other persons, or progressive complications despite optimal insulin therapy
  • Social Security membership or benefit from Social Welfare

Exclusion Criteria:

  • Age< 18 and > 65
  • Diabetes duration < 5 years
  • Criteria specifically related to the islet intraportal injection procedure: hemostasis problem, haemoglobin level < 11g/dL for women and <12g/dL for men, abnormalities of complete blood count, documented liver pathology (alkaline phosphatases, gamma GT, transaminases levels over twice normal values) ; pancreatitis history, gallbladder stones that could potentially migrate; HLA hyperimmunisation (PRA >20%).
  • Criteria related to diabetes complications :

    • Non-stabilized proliferating diabetic retinopathy
    • Creatininaemia > 16 mg/dL
  • Exclusion criteria non-specifically related to islet infusion: evolutive vascular disease, evolutive cardiopathy (especially myocardial infarction less than 6 months ago, cerebrovascular stroke less than 6 months ago, evolutive arteritis with trophic disorders) ; systemic infection including hepatitis C and HIV ; leuconeutropenia ; thrombocytopenia, non-stabilized neoplastic pathology ; pregnancy or project of pregnancy within the next 24 months ; poor therapeutic compliance
  • Criteria related to immunosuppressive protocol : renal failure (glomerular filtration < 35 ml/min/1.73 m²) and/or proteinuria > 0.5 g/24h ; non-treated hyperlipidemia (LDL-C > 130 mg/dL) ; blood pressure > 160/100 mmHg
  • Clinical insulin resistance : assessed by patient's weight, BMI and exogenous insulin requirements (BMI > 30 kg/m² or insulin dose > 0.85 UI/kg/day)

Cosa sta misurando lo studio?

Misure di risultato primarie

Misura del risultato
Misura Descrizione
Lasso di tempo
ß score evaluation 6 months after first infusion (group 1 'immediate registration on infusion waiting list') or 6 months after inclusion (group 2: 'delayed registration on infusion waiting list')
Lasso di tempo: 6 months after first infusion (group 1) or 6 months after inclusion (group 2)
Metabolism evaluated by ß score. This score uses 4 intermediate scores ranging from 0 to 2 associated with the following 4 indicators: HbA1c, basal C peptide (or stimulated C-peptide), daily insulin dose (U/kg) or intake of oral antidiabetic drugs and fasting glycaemia. The total of the intermediate scores ranges from 0 to 8. Islet graft will be considered as successful if the ß score is equal to or greater than 6
6 months after first infusion (group 1) or 6 months after inclusion (group 2)

Misure di risultato secondarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Evaluation of metabolism indicators : ß-score and individual analysis of the 4 components of the ß-score
Lasso di tempo: 6 and 12 months
Metabolism indicators at 6 and 12 months : ß-score (quantitative analysis by mean score comparison), individual analysis of the 4 components of the ß-score (HbA1c, basal C peptide (or stimulated C-peptide), daily insulin dose (U/kg) or intake of oral antidiabetic drugs and fasting glycaemia), lability index, ADRR score, Clarke score
6 and 12 months
Measure of quality of life (SF36, DQOL, DHP)
Lasso di tempo: at inclusion time, at 6 months and at 12 months after first infusion (group 1) or after inclusion (group 2)
Measure of quality of life (SF36, DQOL, DHP) for Group 1 ('immediate registration on infusion waiting list'): at inclusion time, at 6 months and at 12 months after first infusion For Group 2 ('delayed registration on infusion waiting list'): at inclusion time, 6 months after inclusion, at 6 months and at 12 months after first infusion
at inclusion time, at 6 months and at 12 months after first infusion (group 1) or after inclusion (group 2)
Cost evaluation of islet cell infusion
Lasso di tempo: 6 months
Cost comparison between islet cell infusion (group 1 'immediate registration on infusion waiting list')and intensive insulin therapy (group 2 'delayed registration on infusion waiting list') at 6 months, from a hospital perspective as well as a health-insurance system perspective
6 months
Evaluation of side effects and iatrogenic effects
Lasso di tempo: at 6 months and 12 months after infusion
