Autoimmune thyroid disease and chronic urticaria.
Clinical Endocrinology
|June 9, 2007
Summary
Autoimmune thyroid disease is linked to chronic urticaria. Thyroid screening and levothyroxine treatment may benefit patients with chronic hives and thyroid autoimmunity.
Area of Science:
- Immunology
- Endocrinology
- Dermatology
Background:
- Chronic urticaria (CU) is a common dermatological condition.
- Autoimmune thyroid disease (ATD) is a significant comorbidity in some CU patients.
- Understanding the link between CU and ATD is crucial for effective management.
Observation:
- Six cases of ATD associated with CU were identified.
- Literature review covered histopathology, etiology, and pathogenesis of these lesions.
- Prevalence of thyroid disease in CU patients warrants investigation.
Findings:
- Screening for thyrotropin and anti-thyroperoxidase antibodies is recommended for CU patients.
- Negative antibody results do not rule out a thyroid autoimmunity connection.
- Levothyroxine treatment showed improvement in urticaria in 3 of 4 patients with marginal thyroid function abnormalities.
Implications:
- Suggests a potential autoimmune link between chronic urticaria and thyroid disease.
- Recommends thyroid screening in chronic urticaria patients.
- Levothyroxine may be a therapeutic option for refractory chronic urticaria cases with underlying thyroid autoimmunity.

01:28Graves' Disease I: Introduction
Graves' disease is an autoimmune disorder that causes hyperthyroidism, or overactivity of the thyroid gland. It results from autoantibodies called thyroid-stimulating immunoglobulins (TSIs), which bind to thyroid-stimulating hormone (TSH) receptors, leading to overstimulation of hormone production and a hypermetabolic state.EtiologyAlthough considered idiopathic, Graves’ disease has well-established contributing factors. There is a strong genetic component, with increased prevalence in...
01:24Graves Disease II: Pathophysiology
Graves’ disease is an autoimmune disorder characterized by the production of thyroid-stimulating immunoglobulins (TSI) that activate TSH receptors, leading to excessive synthesis and release of thyroid hormones (T3 and T4) and resulting in hyperthyroidism.Among all causes of hyperthyroidism, Graves’ disease is the most common and can happen at any age, though it is more frequent in women. It produces a hypermetabolic state with features such as weight loss, tachycardia, tremor, and heat...
01:29Autoimmune Disorders
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

01:25Hyperthyroidism I: Introduction
Hyperthyroidism is a type of thyrotoxicosis characterized by the thyroid gland's overproduction of the thyroid hormones triiodothyronine (T3) and thyroxine (T4). This hormone excess increases the basal metabolic rate and enhances sensitivity to catecholamines.DiagnosisDiagnosis is based on clinical features and biochemical testing. It typically shows suppressed thyroid-stimulating hormone (TSH) levels below 0.4 mIU/L, with elevated free T3 and/or T4. Additional tests, including thyroid...
01:19Hypersensitivity Reactions: Immune-Complex Reactions
Type III hypersensitivity reactions occur when antigen–antibody complexes form and activate the complement system. Normally, these complexes help the clearance of antigens by phagocytes and red blood cells. However, when large numbers of immune complexes are present, they can deposit in tissues—particularly in the walls of blood vessels—leading to inflammation and tissue injury. These deposits trigger complement activation and neutrophil recruitment, resulting in serum sickness, a systemic...
01:27Hyperthyroidism II: Pathophysiology
Hyperthyroidism is a hypermetabolic state caused by elevated levels of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). It results from dysregulation at the thyroid, pituitary, or immune system level and affects multiple organ systems.PathophysiologyThe most common cause of hyperthyroidism is Graves’ disease, an autoimmune disorder in which antibodies, specifically thyroid-stimulating antibodies (TSAb), a subtype of TSH receptor antibodies (TRAb), bind to and activate TSH receptors...
