COVID-19 vaccine-induced autoimmune hyperthyroidism: Graves' disease

Area of Science:

• Endocrinology
• Immunology
• Vaccinology

Background:

• Graves' disease (GD) is an autoimmune hyperthyroidism caused by thyroid gland attack.
• Factors like genetics, environment, and gut microbiome influence GD development.
• COVID-19 vaccines are crucial, but rare autoimmune adverse events, including GD, are reported.

Purpose of the Study:

• To review and analyze reported cases of Graves' disease following COVID-19 vaccination.
• To elucidate commonalities and potential triggers for vaccine-induced GD.
• To discuss molecular mechanisms of vaccine-induced autoimmunity in GD.

Main Methods:

• Critical analysis of reported cases of Graves' disease post-vaccination.
• Review of literature on autoimmune mechanisms and COVID-19 vaccines.
• Discussion of molecular pathways involved in vaccine-induced autoimmunity.

Main Results:

• Identified potential triggers and commonalities in vaccine-associated Graves' disease cases.
• Highlighted the role of autoimmune mechanisms in GD pathogenesis.
• Detailed molecular mechanisms including antigen presentation, bystander activation, and molecular mimicry.

Conclusions:

• COVID-19 vaccines may trigger Graves' disease through specific autoimmune pathways.
• Understanding these mechanisms is crucial for patient management and vaccination strategies.
• Further research can refine vaccination policies and improve care for autoimmune conditions.
