[Monitoring of treatment for hypothyroidism with L-thyroxine].
The study was aimed at the evaluation of treatment of hypothyroidism with L-thyroxine administration monitored by the determination of T3 and T4 concentrations. The investigations were carried out in a group of 57 patients with hypothyroidism including 37 patients with autoimmune etiology of hypothyroidism, 12 patients after strumectomy and 8 patients after treatment with 131J. The administration of L-thyroxine at a dose of 2 micrograms/kg/day effectively eradicated all symptoms of the disease and led to the normalization of blood serum T3 and T4 values in the majority of patients with autoimmune hypothyroidism. So the majority of women required the daily dose of L-thyroxine of 100-150 micrograms, and the majority of men 125-175 micrograms. Lower dosage of L-thyroxine (50-100 micrograms daily) was required to attain euthyroid state in some patients with postoperative or postradiation hypothyroidism. Monitoring of the therapy by the determination of blood serum T3 and T4 concentrations greatly facilitated the proper choice of the therapeutic dose of L-thyroxine as the return of the thyroid hormone concentrations to normal usually brought about the complete remission of symptoms of the disease. The exception from this rule was only in the case of patients with arterial hypertension and coronary disease in whom, because of the side-effects, lower dosage of L-thyroxine (usually 50 micrograms daily) must have been applied to attain the optimal improvement. The treatment with L-thyroxine caused much less side-effects as compared to the therapy using the dessicated thyroid preparations (Thyroideum).
