The effects of iodine blocking on thyroid cancer, hypothyroidism and benign thyroid nodules following nuclear accidents: a systematic review.

Systematic reviewWomens Health

Systematic review of the effects of potassium iodide (KI) administration following accidental radioactive iodine release on thyroid cancer, hypothyroidism, and benign thyroid nodules.

RCT involving 32 patients with Graves' hyperthyroidism undergoing radioiodine therapy. The study tested the administration of 600 microg inactive iodide for three days to improve 131I kinetics in patients with a short effective 131I half-life.

Thyroid blockade during a radiation emergency in iodine-rich areas: effect of a stable-iodine dosage.

RCTn = 8

The study examined the effect of stable iodine on thyroid gland blockade in patients with hyperthyroidism to evaluate the appropriate dose of iodine prophylaxis during a radiation emergency. Eight patients were given single doses of 50 mg or 100 mg of potassium iodide, significantly suppressing thyroid uptake of (123)I for 24 hours. The study suggests that 38 mg of iodide is as effective as 76 mg for thyroid blockade.

RCTn = 74

RCT of 74 patients with diffuse endemic goitre treated with either levothyroxine alone or a combination of levothyroxine and potassium iodide for 6 months, followed by iodide prophylaxis. Both groups showed significant reduction in goitre size, with a more marked reduction in the combination group. Basal TSH levels were suppressed in both groups, with a tendency for thyroid enlargement in the levothyroxine-only group during iodide prophylaxis.
