Insights
COVID-19 can cause thyroid dysfunction in about 15% of patients, leading to long-term issues like persistent hypothyroidism. Further research is needed to manage these thyroid disorders post-infection.
Area of Science:
- Endocrinology
- Infectious Diseases
- Immunology
Background:
- COVID-19 pandemic has been linked to various endocrine disorders, notably thyroid disease.
- Long-term effects of COVID-19 on thyroid health remain underexplored.
- Understanding this interplay is crucial for managing thyroid disorders in infected individuals.
Purpose of the Study:
- To review the current research on the long-term effects of COVID-19 on thyroid health.
- To identify areas for future clinical studies on post-COVID-19 thyroid dysfunction.
Main Methods:
- A literature search was conducted using keywords: "thyroid disease", "COVID-19", and "long-term".
- Databases searched included PubMed and Google Scholar for relevant clinical research.
Main Results:
- COVID-19 impacts the thyroid via viral invasion, immune response, and HPT axis disruption.
- Thyroid dysfunction occurs in ~15% of COVID-19 patients, presenting as thyrotoxicosis, hypothyroidism, or NTI.
- Long-term effects include persistent hypothyroidism and worsening of autoimmune thyroid conditions, particularly in children.
Conclusions:
- Longitudinal follow-up of patients with thyroid disorders post-COVID-19 is essential for better outcomes.
- Further pathophysiological research can guide strategies for preventing and treating thyroid abnormalities after COVID-19.
Background:
COVID-19 emerged in December 2019 and rapidly became a global pandemic. It has since been associated with the progression of various endocrine disorders, including thyroid disease. The long-term effects of this interplay have yet to be explored. This review explores the relationship between COVID-19 and thyroid diseases, emphasizing thyroid gland function and the clinical implications for managing thyroid disorders in infected individuals.
Objectives:
This narrative review intends to provide insight into the scope of research that future clinical studies may aim to address regarding the long-term effects of COVID-19 infection on thyroid health.
Methods:
Keywords including "thyroid disease", "COVID-19", and "long-term" were used to search PubMed and Google Scholar for updated and relevant clinical research.
Results:
COVID-19 affects the thyroid gland multifacetedly and includes direct viral invasion, immune-mediated damage, and hypothalamic-pituitary-thyroid axis disruption. Approximately 15% of COVID-19 patients experience thyroid dysfunction, which can present as thyrotoxicosis, hypothyroidism, or non-thyroidal illness syndrome (NTI). Noteworthy findings include inflammatory thyroiditis. Long-term effects, including those observed in children, include persistent hypothyroidism and exacerbated pre-existing thyroid-autoimmune conditions. Management of thyroid disorders in COVID-19 patients requires consideration: anti-thyroid drug (ATD) therapy used to treat hyperthyroidism in COVID-19 patients may need adjustment to prevent immunosuppression. Radioactive iodine (ROI) alternatives and interleukin-6 (IL-6) receptor antagonists could offer potential benefits and should be further explored.
Conclusion:
Longitudinal follow-ups post-COVID-19 for patients with new and pre-existing thyroid disorders can improve disease outcomes. In addition, pathophysiological research on thyroid dysfunction in COVID-19 may help develop strategies to prevent and alleviate thyroid gland abnormalities post-COVID-19.

Synthesis and Regulation of Thyroid Hormones
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...
