A starting dosage of 1.6 mcg per kg per day can be initiated, with subsequent incremental changes made every 10 to 12 weeks to achieve this goal. Table 2 summarizes drugs associated with thyroiditis.18, Figure 1 is an algorithm for the diagnosis of thyroiditis.9, Presence of nontender goiter; thyroid function tests; elevated TPO antibody levels, Presence of an elevated TPO antibody level confers risk for many types of thyroid dysfunction and is a general marker of thyroid autoimmunity; a frankly elevated TPO antibody level is more specific for Hashimoto thyroiditis, In type 1 amiodarone-induced thyrotoxicosis there is increased synthesis of thyroid hormone (usually in patients with preexisting goiter), In type 2 amiodarone-induced thyrotoxicosis there is excess release of thyroxine and triiodothyronine into the circulation caused by destructive thyroiditis, Type 1 is treated with antithyroid medications (thioureas) and type 2 is treated with glucocorticoids; in both cases, beta blockers can be used for symptoms of hyperthyroidism1,2. TPO signifies thyroid autoimmune in both under active and over active thyroid diseases. Search dates: June 6, 2011, through February 29, 2012, and March 30, 2014.

In women, there is a prevalence of post-partum thyroid disease of about 6% occurring around 6 months after delivery. Unlike thyroglobulin antibodies, TPO antibodies can stimulate the immune system and cause inflammation in thyroid tissue, leading to the development of thyroid disease [ 2 ]. Herpes sores blister, then burst, scab and heal. Measurement of free T3 is possible, but is often not reliable and therefore not typically helpful. While detecting antibodies is helpful in the initial diagnosis of hypothyroidism due to autoimmune thyroiditis, following their levels over time is not helpful in detecting the development of hypothyroidism or response to therapy.
