What are the symptoms of myxedema coma?
The two most common findings will be altered mental status and hypothermia, along with common findings of hypothyroidism. Other common signs include hyponatremia, hypotension, bradycardia, and hypoventilation. Laboratory results in primary hypothyroidism will show severely low or undetected low serum total T4, free T4, free T3, and elevated TSH. The underlying etiology for most patients is a primary thyroid failure, but secondary, tertiary, and sick euthyroid should be in the differential diagnosis.[48] In euthyroid sick syndrome, TSH will not be as elevated as expected. In a small percentage of patients, central hypothyroidism should be a consideration. In these patients, TSH may be inappropriately low. The method to distinguish central versus primary hypothyroidism is that the associated pituitary hormones will decrease as well. [22]
What is the best treatment for myxedema?
A high index of suspicion, early recognition, admission to intensive care units, and treatment with intravenous levothyroxine and hydrocortisone are paramount in the management of myxedema coma.[3] History of any thyroid dysfunction, thyroid medication, adherence with thyroid medication, thyroid surgery, and history of any drugs that may affect thyroid function require assessment in any patient suspected myxedema coma. [4]
How does thyroid affect cells?
Thyroid hormone influences virtually all cells in the body by activating or repressing a variety of genes after binding to thyroid hormone receptors. Ninety percent of the intracellular thyroid hormone that binds to and influences cellular function is T3, which has been converted from T4 by the removal of an iodide ion. The thyroid hormone receptors associated with the DNA within the target genes are bound to retinoid X receptors at specific thyroid hormone response elements. Once bound, the transcription process begins, and hundreds of new intracellular proteins, mostly enzymes, are formed. One particular gene of importance is the gene that regulates the expression of calcium ATPase, which is especially important in maintaining efficient cardiac output.[20] Thyroid hormones do have some non-genomic effects on cells, which include the regulation of ion channels and oxidative phosphorylation. These effects are possibly under the mediation of the thyroid hormone-binding of the plasma membrane, cytoplasm, and cellular organelles. Other effects of thyroid hormone include increased Na-K-ATPase activity, increased carbohydrate metabolism, increased free fatty acids (decreased cholesterol, phospholipids, and triglycerides), increased vitamin requirements as a consequence of increased enzymes that use vitamins as cofactors, and overall increased metabolism. In light of thyroid hormone being responsible for a vast majority of bodily functions at the genetic and cellular level, it is easy to see how the extreme absence of this hormone, as seen in myxedema coma, is associated with a high mortality rate and has a broad spectrum of presenting symptoms. [21]
What is myxedema coma?
Myxedema is commonly used often in the context of hypothyroidism and myxedema coma, it also means edema of the skin and soft tissue in hypothyroidism.[2] Myxedema coma is a misnomer. Neither the patients have classic nonpitting edema, nor are they in a coma. The most salient feature of myxedema coma is deteriorating mentation.
How common is myxedema coma?
The exact incidence and prevalence of myxedema coma are not known, but some authors estimate an incidence of approximately 0.22 per 1000000 per year in the western world; however, there is no sufficient epidemiological data from other countries.[4] Myxedema coma is more common in females (80% of cases), as hypothyroidism is more common in women (four-fold more than men).[12] The population aged more than 60 years are more liable to have myxedema coma.[13] Since the patients are usually hypothermic, myxedema coma is more common in the winter (90% of cases).[14] This fact is explained by decreased heat production with age and hypothyroidism and decreased thermoregulation with age. [15]
What causes a coma in a patient with hypothyroidism?
Hypothyroidism due to any cause, including autoimmune disease, iodine deficiency, congenital abnormalities, or medications like lithium and amiodarone, can precipitate myxedema coma if left untreated. Even with early diagnosis and treatment of myxedema coma, the mortality rate is variable, with some reports as high as 60% and others as low as 20 to 25% in the presence of advanced intensive support care. Early recognition, a thorough history, physical exam, and early treatment are paramount in managing myxedema coma. This activity reviews the cause, pathophysiology, and presentation of myxedema and highlights the role of the interprofessional team in management.
What are the symptoms of hypothyroidism?
Common cardiovascular symptoms include hypotension, shock, arrhythmia, and heart block. Myxedema causes decreased myocardial contractility and reduced cardiac output, which leads to hypotension.[26] Bradycardia, flattened T waves, low voltage, bundle branch blocks, and complete heart blocks are common EKG findings.[27] Low voltage on EKG can be representative of pericardial effusion due to the accumulation of fluid rich in mucopolysaccharides and merits investigation.[28] Fatal arrhythmias are important to recognize in Myxedema and chronic hypothyroidism[5]. There have been cases showing QT interval prolongations leading to “torsades de pointes,” which resolves with treatment of myxedema. Myocardial infarction is important to rule out as aggressive T4 replacement may increase the risk of myocardial infarction. [29]
