[An improvement in insulin efficacy in patients with type-1 diabetes mellitus following treatment using an insulin infusion pump].

In 8 patients with diabetes mellitus type I two methods for intensified insulin treatment were compared: method of numerous insulin applications and treatment with a subcutaneous insulin pump (Microjet model of "Miles" company). The following were taken into consideration: daily insulin dose, residuary beta-cell secretion (determined by a venous Tolbutamide test and dynamic follow up of C-peptide), peripherial insulin efficiency (M) determined in vivo by an euglycemic hyperinsulinemic clamp-technique (Biostator). The infusion pump treatment imitates the beta-cell function better than the numerous insulin applications. This method of treatment helps in overcoming the insulin deficiency and the jatrogenic hyperinsulinemia and as a result the metabolic compensation and insulin efficiency are improved.
