Match each specific circulating autoantibody with the endocrine disorder it is most classically used to diagnose or evaluate.

  • Thyroid-stimulating immunoglobulins (TSI)Graves disease
  • Anti-thyroid peroxidase (anti-TPO) antibodiesHashimoto thyroiditis
  • Anti-glutamic acid decarboxylase (anti-GAD65) antibodiesType 1 diabetes mellitus
  • Anti-21-hydroxylase antibodiesPrimary adrenal insufficiency

Cevap

Thyroid-stimulating immunoglobulins match with Graves disease; Anti-thyroid peroxidase antibodies match with Hashimoto thyroiditis; Anti-glutamic acid decarboxylase antibodies match with Type 1 diabetes mellitus; Anti-21-hydroxylase antibodies match with Primary adrenal insufficiency.
Each circulating autoantibody specifically corresponds to the pathogenesis of a distinct endocrine disorder. The pairings correctly link the antibody targets to their respective clinical syndromes.

Adım Adım Çözüm

1
Identify the autoantibody responsible for stimulating the thyroid gland.
Thyroid-stimulating immunoglobulins (TSI) are matched with Graves disease.
These antibodies mimic TSH, leading to unregulated hormone production and clinical hyperthyroidism.
2
Identify the primary autoantibody associated with autoimmune hypothyroidism.
Anti-thyroid peroxidase (anti-TPO) antibodies are matched with Hashimoto thyroiditis.
Anti-TPO antibodies indicate immune-mediated thyroid destruction resulting in eventual hypothyroidism.
3
Identify the autoantibody associated with pancreatic beta-cell destruction.
Anti-glutamic acid decarboxylase (anti-GAD65) antibodies are matched with Type 1 diabetes mellitus.
GAD65 is a major autoantigen in the immune destruction of insulin-producing beta cells.
4
Identify the autoantibody linked to autoimmune destruction of the adrenal cortex.
Anti-21-hydroxylase antibodies are matched with Primary adrenal insufficiency.
The 21-hydroxylase enzyme is the primary target in autoimmune adrenalitis (Addison disease).

Anahtar Kavram

Many major endocrine disorders are mediated by specific autoimmune processes, which can be clinically identified through distinct circulating autoantibodies.
