Overview
The exact pathogenesis of de Quervain's thyroiditis is unclear. It is proposed that cytotoxic T cell recognition of complex viral and cell antigens presentation leads to the thyroid follicular cell damage which is responsible for the pathogenesis of de Quervain's thyroiditis. De Quervain's thyroiditis is usually preceded by a viral prodrome and also have a genetic predisposition. HLA B35 and HLA B15/62 are associated with de Quervain's thyroiditis.
Pathophysiology
Pathogenesis
The exact pathogenesis of de Quervain's thyroiditis is unclear, but autoimmunity mechanism is proposed.
- Cytotoxic T cell recognition of viral and cell antigens presented in a complex leading to thyroid follicular cell damage are considered to cause the pathogenesis of de Quervain's thyroiditis.
- De Quervain's thyroiditis is usually preceded by a viral prodrome. Various viral infections are associated with the de Quervain's thyroiditis including mumps, adenovirus, Epstein–Barr virus, coxsackievirus, cytomegalovirus, influenza, echovirus, and enterovirus.[1][2]
Genetics
- De Quervain's thyroiditis is associated with:
- The human leukocyte antigen (HLA) B35
- HLA B15/62 (in rare cases)[3][4]
Pathology
The primary pathology of de Quervain's thyroiditis is:
- Destruction of the follicular epithelium
- Loss of the follicular integrity[1]
