Summary

Recently, Zaborek et al. raised a Poisson regression model for levothyroxine(LT4) dosing scheme to predict individual dose of LT4 after thyroidectomy: daily LT4 dose=e\[2.02+0.01(W)-0.0037(A )-0.098(F)-0.01(B)+0.007(T)+0.108(I)-0.014(M), where W is the weight of the patient (Kg), A is the age of the patient (years), and F is the gender (for women 1, male is 0), B represents the patient's body mass index (BMI), T represents the preoperative TSH level, I represents whether the patient takes iron preparations (1, if not 0), M represents whether the patient takes multivitamins/minerals (1, if not 0). We demonstrated its value with our retrospective data in our center. Therefore, we intend to carry out this randomized controlled trial in order to further evaluate the model. The clinical significance of this method can provide a basis for the future use in clinical optimization of individualized dosing.

DRUG

Levothyroxine Sodium Tablets

For patients in experimental group, initial levothyroxine dose is calculated through the Poisson regression model; and for patients in comparator group, initial levothyroxine dose is calculated through 1.6 ug/kg/d.
