Myxedema coma

Malte Milkau, Friedhelm Sayk
Thyroid storm and myxedema coma are the most severe clinical forms of thyroid dysfunction. While both hyper- and hypothyroidsm are common diseases, thyroid storm and myxedema coma are rare. Due to their unspecific signs and symptoms they are often difficult to diagnose. Both disorders are medical emergencies, which still show a significant mortality. The following article summarizes diagnostic tools and treatment options for these disorders.

Myxedema may be the first presentation of patients with undiagnosed hypothyroidism. Definitive management is with thyroid hormone but supportive measures, identification and treatment of precipitating factors in an appropriately safe environment are vital. There is no consensus about preferred thyroid hormone regimen. Corticosteroid therapy is given until adrenal insufficiency has been excluded. We present here a case of seventy-four years old woman of myxodema coma.

Background: Altered mental status describes impaired mental functioning ranging from confusion to coma and indicates an illness, either metabolic or structural in nature. Metabolic causes include hypothyroidism, hyperuremia, hypo/hyperglycemia, hypo/hypernatremia, and encephalopathy. The structural causes include tumors, brain hemorrhage, infection, and stroke. To our knowledge, this is the first case in which a patient presented with altered mental status from both metabolic (myxedema coma) and structural diseases (frontal meningioma) with vasogenic edema and midline shift...

Myxedema coma is a decompensated hypothyroidism which occurs due to long-standing, undiagnosed, or untreated hypothyroidism. Untreated hypothyroidism is known to affect almost all organs including the heart. It is associated with a decrease in cardiac output, stroke volume due to decreased myocardial contractility, and an increase in systemic vascular resistance. It can cause cardiac arrhythmias and the most commonly seen conduction abnormalities are sinus bradycardia, heart block, ventricular tachycardia, and torsade de pointes...

We herein report the case of myasthenic crisis occurring in a 51-year-old man. He had experienced ptosis, increased body weight with edema, and fatigue with dyspnea. He presented at our emergency department with disturbed consciousness. He was originally diagnosed with myxedema coma, and he required artificial respiration. Because his weakness persisted and he was positive for anti-acetylcholine receptor antibodies and anti-muscle-specific tyrosine kinase antibodies, we diagnosed myasthenic crisis after various examinations...

High-dose intravenous thyroxine (T4) is the preferable treatment for myxedema coma. We describe the clinical course of a 69-year-old man who presented with myxedema coma and received oral levothyroxine (LT4) therapy (1 mg) in a split dose. This suggests split high-dose oral LT4 as a therapeutic option in myxedema coma.

Thyroid emergencies are rare life-threatening endocrine conditions resulting from either decompensated thyrotoxicosis (thyroid storm) or severe thyroid hormone deficiency (myxedema coma). Both conditions develop out of a long-standing undiagnosed or untreated hyper- or hypothyroidism, respectively, precipitated by an acute stress-associated event, such as infection, trauma, or surgery. Cardinal features of thyroid storm are myasthenia, cardiovascular symptoms, in particular tachycardia, as well as hyperthermia and central nervous system dysfunction...

Hypothyroidism is a frequently diagnosed and simply treated disease. If not recognised, however, in time it may develop into the most severe manifestation of hypothyroidism known as myxedema coma. The term "myxedema coma" is generally seen as misleading since most patients do not initially present in a coma. The typical progression is lethargy evolving into stupor and, eventually, into coma with respiratory failure and hypothermia. It mainly affects elderly women, often occurring in winter and is relatively rare...

Thyroid emergencies are major life-threatening endocrine conditions associated with life-threatening disorders resulting from either severe deficiency or excess of thyroid hormones. Deficiency of thyroid hormones may present as myxedema coma whereas excessive hormone production can present as life threatening thyrotoxic storm. The diagnosis of both requires a high index of clinical suspicion. Thyroid storm, in spite of accurate diagnosis, continues to have high fatality, whereas myxedema management has markedly improved with advancement in intensive care facility...

A large pleural effusion causing cardiac tamponade physiology and severe hemodynamic compromise is an uncommon event. We report a case of a 53-year-old woman with severe hypothyroidism presenting with myxedema coma and refractory shock. Her hemodynamic status failed to respond to fluid resuscitation and vasopressors. A transthoracic echocardiogram and chest radiograph demonstrated a pericardial fluid accumulation associated with a large left-sided pleural effusion. Thoracostomy tube insertion resulted in prompt improvement of the patient's hemodynamic status...

RAIONALE: Myxedema coma (MC) is extremely rare but lethal in pediatric patients with hypothyroidism leading to altered mental status and hypothermia. But there is no clinical guideline for such cases. PATIENT CONCERNS: A 6-year-old Chinese girl presented with coma and hypothermia preceded by pneumonia. Her lab results were: free thyroxin (T4) 4.18 pmol/L and thyroid-stimulating hormone (TSH) > 150 μIU/mL with extremely elevated anti-thyroid peroxidase (TPO-Ab) and anti-thyroglobulin...

Myxedema coma, caused by severe lack of thyroid hormone, is characterized by deterioration of mental status, hypothermia, hypotension, hyponatremia, and hypoventilation. We describe an 84-year-old woman who presented with renal failure and new onset severe hypothyroidism leading to challenges in the recognition of myxedema coma.

BACKGROUND: Myxedema coma is a life-threatening and emergency presentation of hypothyroidism. However, the clinical features and outcomes of this condition have been poorly defined because of its rarity. METHODS: We conducted a retrospective observational study of patients diagnosed with myxedema coma from July 2010 through March 2013 using a national inpatient database in Japan. We investigated characteristics, comorbidities, treatments, and in-hospital mortality of patients with myxedema coma...

Myxedema psychosis is uncommon in patients with primary hypothyroidism. Most often, this disease state can be found in patients with Hashimoto thyroiditis or after total thyroidectomy. Chronic hypothyroidism can lead to an insidious onset of psychiatric symptoms in patients, such as dementia, delirium, psychosis, hallucinations, and coma. A 31-year-old man with an unremarkable medical history was brought to the psychiatric emergency department for new-onset aggression, paranoid behavior, and hallucinations for 4 days...

Hypothyroidism is a prevalent condition in the general population that is treatable with appropriately dosed thyroid hormone replacement medication. Infrequently, patients will present with myxedema coma, characterized by hypothermia, hypotension, bradycardia, and altered mental status in the setting of severe hypothyroidism. Myxedema coma has also been known to manifest in a number of unusual and dangerous forms. Here, we present the case of a woman we diagnosed with an uncharacteristic expression of myxedema coma and nonconvulsive seizure complicated by a right middle cerebral artery infarct...

BACKGROUND: Myxedema coma (MC), a medical emergency defined as severe hypothyroidism leading to altered mental status, is more common in older women with hypothyroidism. METHODS/RESULTS: A 7-year-old Caucasian male with chromosome 1q deletion presented with altered mental status preceded by milestone regression. His presenting labs results were: thyroid-stimulating hormone (TSH) 0.501 μIU/ml and free thyroxine (T4) <0.5 ng/dl. His morning cortisol level was 8...

Myxedema coma and thyroid storm are thyroid emergencies associated with increased mortality. Prompt recognition of these states-which represent the severe, life-threatening conditions of extremely reduced or elevated circulating thyroid hormone concentrations, respectively-is necessary to initiate treatment. Management of myxedema coma and thyroid storm requires both medical and supportive therapies and should be treated in an intensive care unit setting.
