Serum levels of thyroid-stimulating hormone in hyperlipoproteinemia

Similar serum lipoprotein abnormalities have been demonstrated in hyperlipoproteinemia type III and hypothyroidism. In this study the levels of thyroid-stimulating hormone in serum were determined in clinically euthyroid patients with different types of hyperlipoproteinemias and in subjects with a normal lipoprotein pattern. The mean value for thyroid-stimulating hormone was significantly higher in the group with hyperlipoproteinemia type III than in normal controls (p smaller than 0.01) and in the group with hyperlipoproteinemia type II A (p smaller than 0.02). The levels of thyroid-stimulating hormone were positively correlated to the triglyceride and cholesterol concentration in the very low density lipoprotein fraction and the ""III-index''.
