The Claim

In patients with giant Graves' disease, a preoperative regimen combining methimazole, levothyroxine, and escalating oral compound iodine solution is associated with normalization of free thyroxine and free triiodothyronine levels in all patients, despite persistent elevation of thyrotropin receptor antibodies above the assay's upper limit.

In plain English

In patients with giant Graves' disease, a specific combination of methimazole, levothyroxine, and escalating oral iodine before surgery consistently brings free thyroxine and free triiodothyronine levels into the normal range, even when thyrotropin receptor antibodies remain elevated.

Why this might work

High doses of iodine block the thyroid from releasing stored hormones and reduce blood flow to the gland, while a synthetic thyroid hormone stops the brain from signaling the thyroid to produce more, allowing hormone levels in the blood to return to normal even though the immune system remains active.

  1. Study: Novel triple-drug regimen for preoperative optimization in giant Graves’ disease: a prospective efficacy and safety trial

    This study gave three specific drugs to people with very large, overactive thyroids and found that their thyroid hormone levels went back to normal before surgery—even though their immune system was still acting up. So yes, the treatment works as described.
