Brief Summary
Islet transplantation is a promising treatment of type 1 diabetes in selected cases. Results are however hampered by a relatively low number of islets surviving the transplantation into the liver, which currently is the site for transplantation. In the present study we compare a new transplantation site (intramuscular in the arm) to the golden standard (the liver) in patients undergoing kidney transplantation from the same donor. In half of the intramuscular transplanted patients, the islets will be mixed with mesenchymal stemcells from the recipient to, possibly, improve the immunological aspects of the transplantation.

Outcome Measures
Primary Outcomes (1)
C-peptide derived from the Mixed Meal Tolerance Test (MMTT)
Percentage of patients in each study group reaching a systemic C-peptide derived from the MMTT above 0.1 nmol/L basal (fasting) and 90-min 0.3 nmol/L 75 (+/-5) and 365 days (+/-14) after kidney transplantation
365 days (+/-14) after kidney transplantation
Study Arms (4)
Intraportal islet transplantation
EXPERIMENTALSubject randomized to the protocol with intraportal islet transplantation and kidney transplantation
Intramuscular islet transplantation
EXPERIMENTALSubject randomized to the protocol with intramuscular islet transplantation and kidney transplantation
Intramuscular transpl with stemcells
EXPERIMENTALSubject randomized to the protocol with intramuscular islet transplantation and where islets have been incubated autologous mesenchymal stemcells. Will also receive kidney transplant
Kidney transplantation only
ACTIVE COMPARATORSubject that only undergoes kidney transplantation
Interventions
All patients will undergo kidney transplantation regardless of arm
Eligibility Criteria
You may qualify if:
- Male and female patients age 18 to 65 years of age.
- Ability to provide written informed consent.
- Mentally stable and able to comply with the procedures of the study protocol.
- Clinical history compatible with type 1 diabetes with onset of disease at \< 40 years of age and insulin-dependence for \> 5 years at the time of enrolment.
- Absence of stimulated C-peptide \<0.1 nmol/L in response to a MMTT.
- All subjects must have received adequate medical treatment of their diabetes under the guidance from an experienced diabetologist.
- All subjects must have renal failure and be eligible for renal transplantation according to local criteria.
You may not qualify if:
- Patients with prior organ transplants
- Patients that qualify for local simultaneous pancreas-kidney transplantation program and who prefer that option
- Patients with body mass index BMI \> 28.
- Insulin requirement \> 1 Unit/kg/day. If the patient is on peritoneal dialysis the same limit is set when the extra carbohydrates in the dialysis fluids have been accounted for.
- Consistently abnormal liver function tests ( \> 1.5 x the upper limit of normal on two consecutive measurements \> 2 weeks apart)
- Unstable diabetic retinopathy
- Hypercoagulability disorder or coagulopathy or International normalized ratio (INR)\>1.5
- Any history of malignancy except for completely resected squamous or basal cell carcinoma of the skin
- Patients with unstable cardiovascular status
- Patients with active infections, unless treatment is not judged necessary by the investigators
- Patients with serological evidence of infection with HIV, hepatitis B (patients with serology consistent with previous vaccination and a history of vaccination are acceptable) or hepatitis C.
