Abstract

Thirty-three patients with Addison's disease were studied. Twenty-two had idiopathic Addison's disease; within this group, 14 patients had clinical or subclinical hypothyroidism, and 16 had increased titres of thyroid autoantibodies. Five patients had tuberculous, and eight had unclassifiable Addison's disease; only one patient in the latter group had evidence of thyroid autoimmunity. A stimulation test with 15 mU bTSH/kg was performed in three patients with Schmidt's syndrome (coexisting Addison's disease and manifest primary hypothyroidism), 15 patients with either subclinical hypothyroidism or increased titres of thyroid autoantibodies, 10 patients without thyroid involvement, and 10 normal controls. There was no detectable increase of 'free' and total thyroid hormones in Schmidt's syndrome. The mean increases after 3-4 h of T4, fT4, T3 and fT3 were 22, 35, 63 and 66%, respectively, in patients without thyroid involvement, and 13, 24, 46 and 45% in patients with subclinical hypothyroidism. 'Free' but not total thyroid hormones rose significantly (P less than 0.01) higher in patients without signs of thyroid involvement than in patients with subclinical hypothyroidism and/or thyroid autoantibodies. Thyroid hormone response to...Continue Reading

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.

Autoimmune Thyroiditis

Autoimmune thyroiditis is an inflammatory disease of thyroid gland due to autoimmune responses leading to lymphocytic infiltration of the gland. It is characterized by the presence of circulating thyroid antigen-specific T-cells and thyroid autoantibodies. Discover the latest research on autoimmune thyroiditis here.

Autoimmune Polyendocrine Syndromes

This feed focuses on a rare genetic condition called Autoimmune Polyendocrine Syndromes, which are characterized by autoantibodies against multiple endocrine organs. This can lead to Type I Diabetes.

Autoimmune Polyendocrinopathies

Autoimmune polyendocrinopathies, also called polyglandular autoimmune syndromes (PGASs), or polyendocrine autoimmune syndromes(PASs), are a heterogeneous group of rare diseases characterized by autoimmune activity against more than one endocrine organ, although non-endocrine organs can be affected. Discover the latest research on autoimmune polyendocrinopathies here.

Addison Disease

Addison's disease, also known as primary adrenal insufficiency and hypocortisolism, is a long-term endocrine disorder in which the adrenal glands do not produce enough steroid hormones. Discover the latest research on Addison's disease here.
