Pearls from Dr. Robert McConnell

Young woman with Grave's disease on methimazole presenting with acute liver injury

2016-06-29

  • Grave's disease diagnosis:
    1. Presentation of new onset ophthalmopathy, large non-nodular thyroid, or other signs of hyperthyroidism
    2. Measure TSH, free T4 - TSH will be suppressed, free T4 will be elevated
    3. Radioactive iodine uptake scan - will have diffusely high radioiodine uptake
    4. Measurement of thyroidal blood flow on ultrasound - will see increased blood flow
    5. Measurement of thyrotropin receptor antibodies

  • 5 Blocks of Treating Thyroid Storm
    1. Block thyroid hormone synthesis with thionamides
    2. Block thyroid hormone release by giving Iodine
    3. Block T4 to T3 conversion with steroids
    4. Block enterohepatic circulation (10-30% of thyroid hormone metabolism occurs in the liver) with bile acid sequestration (cholestyramine)
    5. Block effects of thyroid hormones using beta blockade

  • -Severe hypothyroidism can suppress ACTH.  Always check cortisol and treat for adrenal insufficiency if indicated in patients with severe hypothyroidism/myxedema coma

  • Infection is often a trigger for myxedema coma.  Hypothermia from severe hypothyroidism can mask fever.
