Comparison of administration of recombinant human thyrotropin with withdrawal of thyroid hormone for radioactive iodine scanning in patients with thyroid carcinoma

Article Abstract:

Giving thyroid cancer patients recombinant thyrotropin instead of withdrawing thyroid hormone may not result in an accurate thyroid scan. Thyroid scans are normally done with radioactive iodine to see if these patients have any residual cancer. But the thyroid gland must be stimulated to take up the iodine and this is done by temporarily discontinuing thyroid hormone treatment. Researchers gave 120 cancer patients undergoing a thyroid scan recombinant human thyrotropin so the patients could continue taking thyroid hormone. The scans were not as accurate but the patients had fewer episodes of hypothyroidism and mood disorders.

Effects of thyroxine as compared with thyroxine plus triiodothyronine in patients with hypothyroidism

Article Abstract:

Patients with hypothyroidism may benefit from receiving triiodothyronine as well as thyroxine. Hypothyroidism is abnormally low blood levels of thyroid hormones. Triiodothyronine and thyroxine are hormones produced by the thyroid gland, but most patients with hypothyroidism are only given thyroxine. Researchers treated 33 patients with hypothyroidism with thyroxine for five weeks, and then with both hormones for another five weeks. Patients scored higher on tests of physical status, mood, and intellectual function when they received both hormones.

Subclinical hypothyroidism

Article Abstract:

Guidelines for treating patients with subclinical hypothyroidism are presented. This condition is a mild form of hypothyroidism in which the patient has normal thyroid hormone levels and no symptoms, but has abnormally high levels of thyrotropin.
