Abstract

Spontaneous autoimmune thyroid disease (SATD) shows familial aggregation. Some patients receiving amiodarone treatment have been found to develop thyroid dysfunction. Previously, we reported genetic predisposition among this group of patients, now we inform a prospective study which includes the search for autoantibodies and family history to identify risk factors in amiodarone treated patients, 40 of them with amiodarone related thyroid disfunction, and 100 without it; for comparison, 30 patients with SATD and a control group of healthy subjects were also studied. We looked for the presence of autoantibodies against thyroglobulin, smooth muscle, gastric mucosa, myocardium, mitochondria, epithelial intercellular substance, and basal membrane as well as antinuclear antibodies and rheumatoid factors; in addition the history of thyroid disease in first degree relatives was investigated. Organ-specific antibodies anti-thyroglobulin, gastric mucosa and myocardium were found with increased frequency in the three groups of patients compared with controls (p less than 0.05). The frequency of antihydroglobulin antibodies was similar in patients receiving amiodarone with or without thyroid dysfunction. Prognostic stratification revealed ...Continue Reading

Antiarrhythmic Agents: Mechanisms of Action

Understanding the mechanism of action of antiarrhythmic agents is essential in developing new medications as treatment of cardiac arrhythmias is currently limited by the reduced availability of safe and effective drugs.

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.
