Randomized Open Clinical Study to Evaluate the Efficacy of Selenium Plus Methimazole for Treatment of Graves' Hyperthyroidism
Evaluation of the efficacy of the combined treatment (methimazole plus selenium) in the control of hyperthyroidism as compared to methimazole alone in 30 Graves' disease (GD) untreated patients.
30 untreated GD hyperthyroid patients will be randomized into two groups (A and B). Group A patients will be treated with an anti-thyroid drug (methimazole) at the dose aimed to control hyperthyroidism. Group B patients will be treated with methimazole plus selenium (160 mg daily). Patients will be evaluated at time 0, 45 and 90 days for symptoms of hyperthyroidism (by a specific questionnaire), clinical status (weight, heart rate), laboratory (thyroid function tests, TSHR autoantibodies, serum selenium, index of oxidative stress-MDA, cholesterol, SHBG) and EKG. The aim of the study is to evaluate if the combined treatment (methimazole plus selenium) is more effective than methimazole alone in controlling GD hyperthyroidism.
