[Autoimmune thyroiditis (Hashimoto's thyroiditis): current diagnostics and therapy].

Area of Science:

• Endocrinology
• Immunology
• Pathology

Background:

• Hashimoto's thyroiditis is a prevalent autoimmune disorder affecting the thyroid gland, predominantly in females.
• It is characterized by the development of autoantibodies targeting thyroid peroxidase and thyroglobulin.
• The disease often begins with subclinical hypothyroidism, potentially progressing to persistent hypothyroidism requiring hormone replacement therapy.

Observation:

• Chronic lymphocytic infiltration of the thyroid gland is a hallmark of Hashimoto's thyroiditis.
• Thyroid ultrasound typically reveals a hypoechogenic and inhomogeneous parenchyma.
• Associated autoimmune conditions include vitiligo, Addison's disease, and type 1 diabetes mellitus, sometimes presenting as polyglandular syndrome 2.

Findings:

• The presence of anti-thyroid peroxidase and anti-thyroglobulin antibodies confirms the autoimmune nature of the thyroiditis.
• Progression to overt hypothyroidism with characteristic clinical symptoms necessitates hormonal substitution.
• The characteristic ultrasound findings aid in diagnosis and monitoring disease progression.

Implications:

• Early diagnosis and management of Hashimoto's thyroiditis are crucial to prevent complications of hypothyroidism.
• Understanding the association with other autoimmune diseases is important for comprehensive patient care.
• Further research into the pathogenesis may reveal novel therapeutic targets for autoimmune thyroid disease.
