亚急性甲状腺炎(亚甲炎)可能是甲状腺对多种病毒感染的非特异性炎症反应。有人提出自身抗体阴性的亚甲炎可能是一种非免疫反应过程,但其病因学尚不明确。这种疾病的病程表现多样,大多患者表现为自限性疾病,部分病人可出现一过性甲状腺功能减退症(甲减症)。 Subacute thyroiditis (methylene-actin) may be a non-specific inflammatory response of the thyroid to a variety of viral infections. It has been suggested that autoantibody-negative methyleneimine may be a non-immune reaction, but the etiology is not yet clear. The disease has a diverse course of disease, most patients show self-limited disease, some patients may have transient hypothyroidism (hypothyroidism).
