The efficacy and short- and long-term side effects of radioactive iodine treatment in pediatric Graves’ disease: a systematic review

Lutterman Sarah , Zwaveling-Soonawala Nitash , Verberne Hein , Verburg Frederik , van Trotsenburg Paul , Mooij Christiaan

Background: Graves’s disease (GD) is the most common cause of hyperthyroidism. Maximal 30% of pediatric GD patients achieve remission with anti-thyroid drugs. The majority of patients therefore require definitive treatment. Both thyroidectomy and radioactive iodine (RAI) are often used as definitive treatment for GD. However, data on efficacy, and short- and long-term side effects of RAI treatment for pediatric GD are relatively scarce.Methods: A ...
