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.

Synthesis and Regulation of Thyroid Hormones01:20

Synthesis and Regulation of Thyroid Hormones

Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
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...

Functions of Thyroid Hormones

The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

The Thyroid Gland01:23

The Thyroid Gland

The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

Psychoneuroimmunology: Diabetes and Cancer

Chronic stress has been linked to both the onset and progression of serious health conditions, including Type 2 diabetes and cancer. Type 2 diabetes, a widespread chronic illness, is closely associated with obesity and insulin resistance, both of which often worsen under stress. Studies indicate that men experiencing high levels of chronic stress face a 45% higher risk of developing diabetes compared to those with minimal stress. Stress triggers physiological responses that elevate blood...

Psychoneuroimmunology: Cardiovascular Disease

Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.
A key area of focus in PNI is the relationship between stress and coronary...

Stress and Mental Health01:30

Stress and Mental Health

Chronic stress profoundly affects mental health, significantly influencing mood, behavior, and overall quality of life. Research closely links chronic stress with mental health conditions such as depression, anxiety, and substance use disorders. Ongoing exposure to stress can lead to physiological and psychological changes, initiating a cycle of emotional distress and maladaptive coping mechanisms.
Individuals with depression often experience challenges in both their personal and professional...
