Eligibility of diabetic patients for islet transplantation alone.
Since the Edmonton protocol, islet transplantation alone (ITA) offers the prospect of adequate glycemic control in type 1 diabetes without kidney failure. Patient motivation, evolution of diabetic complications, and hypoglycemia unawareness have to be balanced against the risks of portal puncture and long-term immunosuppressive therapy. The aim of this work was to assess the profile of 41 type 1 diabetic patients (21 men and 20 women of age 18 to 63 years) for whom islet transplantation was considered, between January 2000 and December 2002. Thirty-one of these patients lived in the area. The patients were divided into 3 groups according to their recruitment: 20, personal initiative (G1); 8, recruited from hospitalization (G2) for marked glycemic imbalance; and 13, (G3) referred by their diabetologist. Among this series of 41 patients, 14 (8 in G1, 4 in G2, and 2 in G3) did not fit the eligibility criteria, mainly because of a positive C-peptide, kidney failure, desire for pregnancy (G1, G3), liver disorders related to alcohol or iron overload related to HFE heterozygosity (G2), or good glycemic balance (G3). Sixteen did not wish to proceed after the first information step, 6 of these being more interested in a pump. Eleven, mainly recruited in G1 or G3, went through the clinical pretransplantation assessment. Among these, 2 have undergone transplantation, another 1 is enlisted. Therefore, it appears that patient motivation and information to the diabetologists are two important issues in the recruitment of patients eligible for islet transplantation. Equally important is the measurement of C-peptide, plasma creatinine, and microalbuminuria.
