Radioactive iodine or surgical procedure linked to decreased mortality threat in sufferers with hyperthyroidism


Hyperthyroidism remedy like radioactive iodine or surgical procedure was related to a decreased threat for loss of life, based on analysis being offered Saturday at ENDO 2023, the Endocrine Society’s annual assembly in Chicago.

Hyperthyroidism or an overactive thyroid gland is frequent, affecting as much as 3% of the inhabitants, and is related to long-term antagonistic cardiac and metabolic penalties. The optimum remedy selection stays unclear.”

Boelaert and colleagues recognized 55,318 sufferers with newly recognized hyperthyroidism, handled with antithyroid medicine (ATD; 77.6%), radioiodine (14.6%), or thyroidectomy (7.8%) from a U.Ok. population-based digital well being document database for the EGRET Research.

They examined all-cause mortality, main cardiovascular occasions (MACE: cardiovascular loss of life, coronary heart failure, or stroke), and post-treatment weight problems. The typical follow-up was roughly 12 years.

These handled with antithyroid medicine had an estimated imply survival of 12 years, based on the information. Survival elevated in these handled with radioiodine by 1.7 years and thyroidectomy by 1.1 years. Folks handled with antithyroid medicine had an estimated 10.2% threat of MACE, which considerably elevated by an extra 1.3% with radioiodine however not with thyroidectomy.

These definitive remedies had been related to a considerably elevated survival, regardless of a small elevated threat for total weight achieve. For instance, thyroidectomy was related to an elevated probability of weight problems in each women and men. Radioiodine remedy led to elevated weight problems threat in ladies, however not in males.

“Our findings are vital and can inform decision-making processes for sufferers and clinicians when contemplating optimum remedy choices and are more likely to influence scientific observe pointers sooner or later,” Boelaert mentioned.
