Purpose: Variation of plasma thyroid hormone levels influences insulin sensitivity and peripheral glucose disposal. High thyroxin dose administration to healthy humans induces insulin resistance, whereas moderate doses increase peripheral glucose disposal. An open-labeled, randomized and placebo-controlled intervention was performed in euthyroid type 2-diabetic patients, to examine the effect of a small thyroxin dose within the euthyroid range on postprandial forearm muscle glucose uptake, insulin sensitivity, in vitro glucose uptake and GLUT4 recruitment in the plasma membrane of monocytes. Methods: A meal was given to eleven euthyroid, treatment-naive, type-2 diabetic patients (aged 43 ± 3.8 yrs, BMI 27.48 ± 1.39 kg/m2, T3 119 ± 5.7 ng/dl, T4 8,13 ± 0.46 μg/dl, TSH 1.51 ± 0.14 μU/ml, FT4 1.272 ± 0.047 ng/dl) before and..
