Thyroid storm, also referred to as thyrotoxic crisis, is an acute, life-threatening, hypermetabolic state induced by excessive release of thyroid hormones (THs) in individuals with thyrotoxicosis.

What causes Thyrotoxic crisis?
Thyroid storm occurs due to a major stress such as trauma, heart attack, or infection in people with uncontrolled hyperthyroidism. In rare cases, thyroid storm can be caused by treatment of hyperthyroidism with radioactive iodine therapy for Graves disease.
What are the signs and symptoms of thyrotoxicosis?
Symptoms of overt thyrotoxicosis include heat intolerance, palpitations, anxiety, fatigue, weight loss, muscle weakness, and, in women, irregular menses. Clinical findings may include tremor, tachycardia, lid lag, and warm moist skin.
How is a thyrotoxic crisis treated?
Treatment directed at thyroid hormone synthesis and secretion by the thyroid gland. Antithyroid treatment: Carbimazole or propylthiouracil orally. However, anti-thyroidal therapy is sometimes limited due to rare and serious side-effects or failure to control disease progression.
What is the most common cause of thyrotoxicosis?
The most common cause of thyrotoxicosis is Graves disease (50-60% of cases). Graves disease is an organ-specific autoimmune disorder characterized by a variety of circulating antibodies, including common autoimmune antibodies, as well as anti-TPO and anti-TG antibodies.
What are the signs of a thyroid storm?
Symptoms
- Fever. Typically anything over 100.5 F.
- Diarrhea and vomiting. This can include nausea and abdominal pain.
- Nervousness and confusion. People affected by a thyroid storm may have terrible anxiety and become delirious.
- Unconsciousness. If untreated, the affected person may fall into a coma.
Why is hydrocortisone given in thyroid storm?
Corticosteroids inhibit peripheral conversion of T4 into T3 and have been shown to improve outcomes in patients with thyroid storm.
Is thyrotoxicosis an emergency?
Background. Thyroid storm is a rare clinical picture seen in severe thyrotoxicosis. The condition is a critical emergency presentation occurring in 1-2% of hyperthyroid patients, with treated mortality rates reported between 10-30%.
How serious is thyrotoxicosis?
Untreated, thyrotoxicosis can lead to serious medical complications such as heart rhythm disturbances and Osteoporosis, caused from the long-term effects of hormone overproduction.
Can thyrotoxicosis be cured?
Yes, there is a permanent treatment for hyperthyroidism. Removing your thyroid through surgery or destroying your thyroid through medication will cure hyperthyroidism. However, once your thyroid is removed or destroyed, you’ll need to take thyroid hormone replacement medications for the rest of your life.
What are the signs of thyroid crisis from Graves disease?
The sudden and drastic increase in thyroid hormones can produce many effects, including fever, sweating, vomiting, diarrhea, delirium, severe weakness, seizures, irregular heartbeat, yellow skin and eyes (jaundice), severe low blood pressure, and coma. Thyroid storm requires immediate emergency care.
How do you control a thyroid crisis?
The approach to treatment of thyroid storm includes the following:
- Supportive measures.
- Antiadrenergic drugs.
- Thionamides.
- Iodine preparations.
- Glucocorticoids.
- Bile acid sequestrants.
- Treatment of the underlying condition.
- Rarely plasmapheresis.
Is PTU better than methimazole?
Methimazole — Methimazole is usually preferred over propylthiouracil because it reverses hyperthyroidism more quickly and has fewer side effects. Methimazole requires an average of six weeks to lower T4 levels to normal and is often given before radioactive iodine treatment.
Can thyrotoxicosis causes death?
Thyroid storm is a life-threatening health condition that is associated with untreated or undertreated hyperthyroidism. During thyroid storm, an individual’s heart rate, blood pressure, and body temperature can soar to dangerously high levels. Without prompt, aggressive treatment, thyroid storm is often fatal.
Is thyrotoxicosis an autoimmune disease?
GD is a systemic autoimmune thyroid disorder characterized by the infiltration of immune effector cells and thyroid-antigen-specific T cells into the thyroid and thyroid stimulating hormone receptor (TSHR) expressing tissues, i.e. orbit, skin, with the production of autoantibodies to well-defined thyroidal antigens.
Can thyrotoxicosis cause heart failure?
Heart failure resulting from thyrotoxicosis is due to a tachycardia-mediated mechanism leading to an increased level of cytosolic calcium during diastole with reduced ventricular contractility and diastolic dysfunction, often with tricuspid regurgitation.
