RESUMO
We present the study of a patient suffering insulin resistance with Werner's syndrome which had abnormal glucose tolerance determined by euglycemic fixing ("Clamp") using an artificial pancreas (Biostator GCIIS, Miles Martin) and the binding of insulin to its receptor in erythrocytes. The results obtained show a dose-response curve of insulin serum levels to dextrose infusion rate, shifted significantly to the right and bottom which indicates a diminished insulin sensitivity; similarly a moderate decrease in receptor is obtained with no decrease in their affinity and absence of abnormalities in contraregulatory hormones. These results are compatible with a postreceptor alteration.
