Abstract

Currently type-I diabetes mellitus is treated with exogenous insulin administration, but traditional insulin therapy does not prevent long-term systemic complications and therefore alternatives should be sought. Presently the only option is to substitute the insulin-producing beta cells in order to obtain a more physiological way to deliver insulin. Simultaneous kidney and pancreas transplantation is an established procedure. Pancreas transplantation, however, is a major surgical procedure with a high rate of complications. Transplantation of the isolated insulin-secreting islets of Langerhans is an alternative approach, which is easier and safer than whole organ transplantation. Since 1990, clinical trials of islet transplantation have begun in a few specialized centers worldwide and the International Islet Registry counting 305 human islet allografts at the end of 1995. Insulin independence at 1 year was achieved in 8% of the patients, but 20% of cases showed a graft function with a normal basal C peptide and improved glycemic regulation. We review here the different aspects of human islets of Langerhans allotransplatation, namely historical aspects, indications, isolation and purification procedures and the results obtained.
