Objective:

To investigate the role of SARS-CoV-2 infection and vaccination in inducing various types of autoimmune thyroiditis and the production of anti-TPO antibodies across different participant groups.

Approach:

Key Findings:

• Increased anti-TPO antibodies were observed in hospitalized COVID-19 patients compared to healthy controls, indicating a potential autoimmune response.
• Post-vaccination studies showed conflicting results regarding anti-TPO levels, with some indicating moderate increases after mRNA vaccines, suggesting a need for further investigation.
• No significant changes in anti-TPO levels were found in recipients of inactivated virus vaccines, highlighting differences in vaccine-induced immune responses.

Interpretation:

The findings suggest a potential link between COVID-19 infection and vaccination with autoimmune thyroiditis, possibly through mechanisms like molecular mimicry and direct viral injury to thyroid cells, warranting further exploration.

Limitations:

• The study's cross-sectional design limits causal inferences, and the reliance on convenience sampling may affect the generalizability of the results.
• Few studies have focused on individuals with pre-existing thyroid disease, indicating a gap in the literature that this study aims to address.

Conclusion:

COVID-19 infection and vaccination may influence the development of autoimmune thyroiditis, warranting further investigation into their cumulative effects, particularly in diverse populations.
