Overview
The exact pathogenesis of de Quervain's thyroiditis is unclear. It is proposed that cytotoxic T cell recognition of viral and cell antigens presentation in a complex 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. Cytotoxic T cell recognition of viral and cell antigens presented in a complex leading to thyroid follicular cell damage has been proposed as 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.
Genetics
- De Quervain's thyroiditis is associated with the histocompatibility antigen (HLA) B35.
- In some cases of De Quervain's thyroiditis HLA B15/62 positivity was also reported.
Pathology
The primary pathology of de Quervain's thyroiditis is:
- Destruction of the follicular epithelium
- Loss of the follicular integrity
