A
26
Q

What are the three most common and clinically significant subtypes of thyroiditis?

A

Yhe three most common and clinically significant subtypes of thyroiditis:
(1) Hashimoto thyroiditis
(2) granulomatous (de Quervain) thyroiditis
(3) subacute lymphocytic thyroiditis.

27
Q

What is Hashimoto Thyroiditis?

A
28
Q

Pathogenesis of Hashimoto thyroiditis?

A

Figure 24.10 Pathogenesis of Hashimoto thyroiditis. Breakdown of peripheral tolerance to thyroid autoantigens results in progressive autoimmune destruction of thyroid cells by infiltrating cytotoxic T cells, locally released cytokines, or antibody-dependent cytotoxicity.

Q

What is Granulomatous Thyroiditis?

A

Granulomatous thyroiditis (also called De Quervain thyroiditis) occurs much less frequently than does Hashimoto thyroiditis. The disorder is most common between 40 and 50 years of age and, like other forms of thyroiditis, affects women more often than men (4:1).

Q

TGA Guidelines - Antithyroid drug therapy for primary hyperthyroidism?

A

Primary hyperthyroidism (ie Graves disease, toxic multinodular goitre, toxic adenoma) is usually managed initially with an antithyroid drug with the aim of achieving euthyroidism. Some patients can achieve remission with an antithyroid drug alone (eg patients with mild Graves disease), while other patients use an antithyroid drug in preparation for definitive treatment (ie radioiodine or thyroidectomy). Antithyroid drugs gradually relieve the symptoms of thyrotoxicosis as the patient becomes euthyroid. In the interim, beta-blocker therapy can be used for symptomatic patients to rapidly improve symptoms.

A
49
Q

Clinical Features of Graves’ Disease?
- Treatment?

A

Graves disease is treated with β-blockers, which dampen symptoms related to increased sympathetic nervous system activity (e.g., tachycardia, palpitations, tremulousness, and anxiety), and by measures that decrease thyroid hormone synthesis, such as the administration of thionamides (e.g., propylthiouracil), radioiodine ablation, and thyroidectomy. Surgery is used mostly in patients who have large goiters that are compressing surrounding structures.
