European studies suggest a disease incidence of 1 to 2 people affected per 100,000 population with a prevalence of 10 to 25 people per 100,000 population. [ 42 ] [ 46 ] [ 47 ] [ 48 ] The disease has a bimodal peak occurring between the ages of 10 and 20 and then later in life between the ages of 40 and 50.
Hashimoto's thyroiditis, also known as chronic lymphocytic thyroiditis, Hashimoto's disease and autoimmune thyroiditis, is an autoimmune disease in which the thyroid gland is gradually destroyed. [7] [1] Early on, symptoms may not be noticed. [3] Over time, the thyroid may enlarge, forming a painless goiter. [3]
They are found in 70% of Hashimoto's thyroiditis, 60% of idiopathic hypothyroidism, 30% of Graves' disease, a small proportion of thyroid carcinoma and 3% of normal individuals. [ 1 ] [ 3 ] Anti-TPO antibodies are present in 99% of cases where thyroglobulin antibodies are present, however only 35% of anti-TPO antibody positive cases also ...

Positive ANA as well as anti-DNA antibodies have been reported in patients with autoimmune thyroid disease. [67] [68] ANA can have a positive test result in up to 45% of people with autoimmune thyroid conditions or rheumatoid arthritis and up to 15% of people with HIV or hepatitis C.
Occurrences of AIT are most common in patients with prior thyroid disease such as Hashimoto's thyroiditis or thyroid cancer. The most common cause of infection in children is a congenital abnormality such as pyriform sinus fistula. [5] In most cases, the infection originates in the piriform sinus and spreads to the thyroid via the fistula. [7]
Hashitoxicosis, which can be abbreviated "Htx", [1] is a transient hyperthyroidism caused by inflammation associated with Hashimoto's thyroiditis disturbing the thyroid follicles, resulting in excess release of thyroid hormone. [2
