The most likely reasons for the low predictive value of TSH-receptor antibodies (TRAbs) determinations in previous investigations are the biological heterogeneity of TRAbs and changes of the different stimulating (TSAb) or blocking (TSBAb) antibody bioactivities of TRAbs during the course of Graves' disease (GD), which have not been taken into account in most previous studies. Furthermore, in a...

Graves’ disease (GD) accounts for majority of hyperthyroidism in children. The best treatment option for hyperthyroidism in children has been controversial for many years. There is poor long term remission with antithyroid drugs in children, though the duration of therapy in children is also debatable. So, many children are treated with radioiodine-131(RAI) ablation or surgical thyroidectomy as...

A T4 suppression test involving 24-h thyroidal 131I uptake was carried out on patients with Graves' disease during therapy with an antithyroid drug. Thirty-three patients received propylthiouracil (PTU) for at least 1 year. Each patient was given 75 micrograms L-T3 daily for 8 days in conjunction with PTU (50 mg/day) at the time of the experiment and then the 24-h thyroidal 131I uptake (post T3...

A 15-year-old girl presented with chorea as a first sign of Graves' hyperthyroidism. Chorea abated with antithyroid drug treatment and reappeared when hyperthyroidism recurred but not when thyrotropin receptor antibodies increased after administration of (131)I. Therefore, chorea in this patient is associated with hyperthyroxinemia and not with autoantibodies.

We report two patients whose thyrotoxicosis failed to respond to conventional treatment with carbimazole. The patients remained persistently hyperthyroid, both clinically and biochemically, despite several months of carbimazole therapy at the maximum recommended doses. Prednisolone 20 mg per day was then given in addition to the antithyroid drug and a dramatic response observed in both cases. T...

yperthyroidism is a common endocrine disorder. A recent national survey found a prevalence of 0.5% in the general US population. The most common cause of hyperthyroidism is Graves’ disease, which accounts for 80% to 90% of cases. Three treatment options currently are available for patients with Graves’ disease: radioiodine therapy, antithyroid drugs, and thyroidectomy. The clinician should choo...

Managing thyroid dysfunction is simple at first glance, the idea is to bring hormone levels in the euthyroid range, treat with antithyroid drugs, radio-iodine or surgery if toxic and replace with thyroxine or T3 if hypothyroid. Complexities arise when there are coexisting conditions that affect the thyroid or are affected by thyroid dysfunction and this review will deal with the special situati...

The effect of the thyroid hormone on the rate of brain protein synthesis in rats was studied. Experiments were conducted on three groups of rats given 6-propyl-2-thiouracil (PTU, a thyroid inhibitor) without a triiodothyronine (T3) treatment, those treated with PTU + T3, and those treated with neither PTU nor T3 (control). The fractional rates of protein synthesis in the brain, liver, and kidne...

This report describes three women with hyperemesis gravidarum caused by previously undiagnosed thyrotoxicosis. All three women were eight weeks pregnant and only one woman had typical features of thyrotoxicosis. Hyperemesis could not be controlled by anti-emetics. The patients were successfully treated with antithyroid drugs. Anti-thyroid treatment does not need to be continued once resolution ...
