title: [Long-term treatment of diabetes with transplantation of a pancreatic segment].
abstract: BACKGROUND
  Successful transplantation of the pancreas is at present the only way how to ensure on a long-term basis an almost physiological regulation of the carbohydrate metabolism in type 1 diabetics. So far it is, however, indicated mainly in patients with already advanced microangiopathy where at the same time also renal transplantation is planned and long-term experience is so far limited. The objective of the submitted paper is to report on the development of metabolic compensation and its impact on the development of microangiopathic changes in type 1 diabetics where the complete function of both grafts persisted more han five years.
  
  
  RESULTS
  From a group of 34 combined transplantations of a pancreatic segment with an obliterated duct and a kidney, implemented in 1983-1988 in the Institute of Clinical and Experimental Medicine, a group of nine type 1 diabetics was followed up where the independence on exogenous insulin and haemodialyzation treatment persisted for or still persists for 5-8 years. After annual intervals the blood sugar level was examined, the intravenous glucose to tolerance test, free insulin levels, glycosylated haemoglobin, an ophthalmological and neurological examination was made, incl. the peripheral and autonomous system, and by means of a standard questionnaire the quality of life before and after transplantation was assessed. In all examined subjects normal blood sugar levels were recorded. The fasting insulin levels in transplant recipients were higher than in healthy subjects (22 vs. 10.2 microU/ml, p < 0.01) while in the course of the blood sugar curve corresponding levels were recorded. Glycosylated haemoglobin remained after 5 years quite or almost normal (4.2-7.2%). The coefficient of glucose assimilation after 5 years varied in the range from 0.7 to 1.9% min. Hypoglycaemic states were not recorded. In none of the recipients in the course of the investigation deterioration of the ophthalmological finding was observed and in three patients improvement was recorded. Symptoms of somatic polyneuropathy improved in all patients but signs of vegetative neuropathy remained unchanged. In all recipients psychic, physical and social rehabilitation as well as the general quality of life improved markedly.
  
  
  CONCLUSIONS
  Although the group of investigated patients is so far small, the authors provided evidence that combined transplantation of the pancreas and kidney can influence in a very favourable way the quality of life and development of microangiopathic complications. As the success rate of transplantations of the pancreas in increasing and the risk of surgical complications is declining due to improving surgical techniques, the authors conclude that combined transplantation of the pancreas and kidney is at present the optimal therapeutic procedure in type 1 diabetics with chronic renal insufficiency and that indication for transplantation of the pancreas could be moved to earlier stages of diabetes when it would be possible to influence the development of diabetic microangiopathy more favourably.
