Natural History of Thyroid Function Disorders

Recruiting

• Conditions: Hypothyroidism; Grave's Disease; Hyperthyroidism

• Registration Number: NCT00001159
• Lead Sponsor: National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK)

Brief Summary

Participants in this study will be patients diagnosed with or suspected to have a thyroid function disorder. These conditions may include: hypothyroidism, hyperthyroidism, thyroid hormone resistance, Graves' Dermopathy, and thyroid-stimulating hormone (TSH) secreting pituitary adenomas.

The main purpose of this study is to further understand the natural history, clinical presentation, and genetics of thyroid function disorders. Many of the tests performed are in the context of standard medical care that is offered to all patients with thyroid function disorders. In addition, blood and tissue samples may be taken for research and genetic studies.

Detailed Description

Patients with thyroid function abnormalities (hyperthyroidism, hypothyroidism) are studied and treated in this protocol. Patients undergo routine history and physical examination, standard endocrine blood and urine tests, a standard TRH test, thyroid nuclear medicine scans, thyroidal radioiodine (RAI) or technetium (99mTc) uptake measurements, as well as X-ray, computed tomography (CT) or magnetic resonance imaging (MRI) studies or other standard diagnostic procedures, as clinically indicated.

The goals of this study are:

* 1. To understand the pathophysiology and various causes of thyroid function abnormalities (e.g., hyperthyroidism, hypothyroidism).

* 2. To longitudinally follow the effects of standard therapies for patients with abnormal thyroid functions.

* 3. To create a repository of clinical data and biospecimens for future research of thyroid disorders.

Our objective will be accomplished by obtaining clinical data and biospecimens during standard care procedures and tests performed on enrolled subjects being evaluated as an outpatient in the clinic or as an inpatient at the NIH Clinical Center.
