Subacute (de Quervain's)Thyroiditis Subacute thyroiditis is believed to be triggered by a viral infection. It occurs in two phases—a hyperthyroid phase and a hypothyroid phase, followed by recovery. The hyperthyroid phase causes a patient's thyroid gland to be tender to touch and abnormally enlarged (called a Silent (Painless) Thyroiditis Silent thyroiditis, also called painless thyroiditis, causes a mild, short-lived hyperthyroid phase that is sometimes followed by a hypothyroid phase, and then recovery. With this type of thyroiditis, the thyroid gland remains normal in size or becomes mildly enlarged, but the patient doesn't experience any neck pain. • Interferon-alpha: This medication is used to treat certain cancers, like • Amiodarone: This drug is used to treat patients with various types of heart arrhythmias. • Lithium: This drug is used to treat bipolar disorder and sometimes (off-label) unipolar depression. • Tyrosine kinase inhibitors: These targeted drugs are used to treat different cancers, such as • Checkpoint inhibitor drugs: These drugs, such as Yervoy (Ipilimumab) and Tecentriq (Atezolizumab), work by boosting a patient's immune system response against cancer cells. Chronic Infectious Thyroiditis Chronic infectious thyroiditis is usually caused by a fungus and tends to occur in patients with a weakened immune system. Thyroid gland tenderness is milder than in acute infectious thyroiditis and occurs on both sides. Some patients with this type of thyroiditis d...
