Thyroid storm
Thyroid storm is a rare but severe and life-threatening complication of hyperthyroidism. It occurs when an overactive thyroid leads to hypermetabolism, which can cause death from cardiac arrest or multiple organ failure.
It is characterized by a high fever (temperatures often above 40 °C / 104 °F), fast and often irregular heart beat, elevated blood pressure, vomiting, diarrhea, and agitation. Hypertension with a wide pulse pressure occurs in early to mid crisis, with hypotension accompanying shock occurring in the late stage. Heart failure and heart attack may occur. Death may occur despite treatment. Most episodes occur either in those with known hyperthyroidism whose treatment has stopped or become ineffective, or in those with untreated mild hyperthyroidism who have developed an intercurrent illness (such as an infection).
The primary treatment of thyroid storm is with inorganic iodine and antithyroid drugs (propylthiouracil or methimazole) to reduce synthesis and release of thyroid hormone. Temperature control and intravenous fluids are also mainstays of management. Beta blockers are often used to reduce the effects of thyroid hormone. Patients often require admission to the intensive care unit.
As a life-threatening medical emergency, thyroid storm has a mortality rate of up to 25% despite treatment. Without treatment, the condition is typically fatal, with a mortality rate of 80–100%. Historically, the condition was considered untreatable, with hospital mortality rates approaching 100%.
Thyroid storm is characterized by an acute onset of symptoms of hyperthyroidism (fast heart rate, restlessness, agitation) accompanied by other features such as fever (temperatures often above 40 °C/104 °F), hypertension, mental status changes, diarrhea, and vomiting.
Individuals can exhibit varying signs of organ dysfunction. Patients may experience liver dysfunction, and jaundice (yellowing of the skin), which is considered a poor prognostic sign. Cardiac (heart) symptoms include abnormal heart rhythms, myocardial infarction (heart attack), and congestive heart failure, which may lead to cardiovascular collapse. Mortality can be as high as 20–30%.
In some situations, individuals may not experience the classic signs of restlessness and agitation, but instead present with apathetic signs of weakness and confusion.
The transition from hyperthyroidism to thyroid storm is typically triggered by a non-thyroidal insult including, but not limited to fever, sepsis, dehydration, myocardial infarction, and psychiatric diseases.[vague] Individuals are at higher risk of thyroid storm if their hyperthyroidism is incompletely treated or if their anti-thyroid drugs are discontinued. Many of these individuals have underlying primary causes of hyperthyroidism (Graves' disease, toxic multi-nodular goiter, solitary toxic adenoma, or amiodarone). However, thyroid storm can occur in individuals with unrecognized thyrotoxicosis experiencing non-thyroid surgery, labor, infection, or exposure to certain medications and radiocontrast dyes.[citation needed]
