Protocol summary
The aim of this study was to investigate the effectiveness of continuous Methimazole treatment and to compare health status, and results of neuropsychological testing in patients receiving long-term continuous Methimazole to those of patients on replacement thyroxine doses following radioiodine-induced hypothyrodidm. We enrolled 239 patients with diffuse toxic goiter who had recurrence of hyperthyroidism and had been referred to an expert private clinic. One hundred and four patients were randomized into two, the methimazole and the radioiodine treatment groups. The remaining 135 patients voluntarily enrolled into two groups. After monthly visits for the first 3 months of therapy, all patients in both groups were visited every 3 months for the first year and, every 6 months thereafter. The following measurements were done for both groups: 1- questionnaires 2- physical exam and determining thyroid size 3- TSH, T3, FT4, anti TPO and TSI 4- serum lipids 5- cardiac function 6- bone mineral density 7- Neuro-psychology tests 8- treatment costs.

هدف از این مطالعه مقايسه اثرات درمان طولاني مدت با متي مازول با يد راديواكتيو در پركاري تيروئيد بود. تعداد 239 بیمار پرکاری تیرویید که دچار عود بیماری شده و به مطب فوق تخصصی غدد ارجاع شده بودند وارد مطالعه شدند. 104 بیمار به طور تصادفی به دو گروه درمان دائم با متی مازول و درمان با يد راديواكتيو تقسیم شدند. همچنین تعداد 135 بیمار به انتخاب خود در گروه ها قرار گرفتند. بیماران هر ماه تا 3 ماه، هر 3 ماه تا یکسال و سپس هر 6 ماه پیگیری شدند. موارد زير در هر دو گروه انجام شد: 1- تكميل پرسشنامهها 2- معاينه باليني و تعيين اندازه تيروئيد 3- تستهاي غلظت FT4، T3، TSH آنتيبادي ضد TPO و TSI 4- غلظت ليپيدهاي سرم 5- تستهاي عملكرد قلبي 6- تراكم استخوان 7- تستهاي رواني عصبي حركتي 8- هزینه های درمانی.

The methimazole arm of the trial is further randomized to either continue methimazole treatment for an additional period to reach a total of 60 to 120 months (the "long-term" group), or discontinue treatment after the conventional period of 18 to 24 months of treatment (the "conventional" group). This randomization is also done through using the Table of Random Digits.

گروه "متي مازول" اين كارآزمايي به طور تصادفي به دو گروه تقسيم مي شوند. يك گروه درمان را بعد از دوره اوليه قطع مي كنند ("گروه درمان معمول") و گروه ديگر به مدت بيشتري درمان را ادامه مي دهند به نحوي كه مجموع طول دوره درمان با متي مازول به ٦٠ تا ١٢٠ ماه برسد ("گروه درمان طولاني مدت"). اين تقسيم تصادفي نيز بر اساس جدول اعداد تصادفي صورت مي گيرد.

Protocol summary
Study aim
The aim of this study is to investigate the effectiveness of two different regimens of continuous Methimazole treatment in comparison to radioactive iodine and to compare health status, and results of neuro-psychological testing in patients receiving long-term continuous Methimazole to those of patients on replacement thyroxine doses following radioiodine-induced hypothyroidism.
Design
Patients will be assigned to the respective groups and samples will be obtained at baseline. The radio-iodine group patients will be followed up every 12 months for the duration of treatment.
Patients in the "Methimazole" group will further be randomly assigned to either "Conventional Length" or "Long-term" groups and will be followed up every 6 months.
Settings and conduct
Consecutive patients with untreated first episodes of Graves’ hyperthyroidism who fulfill the inclusion criteria and do not have any of the exclusion criteria are recruited from among those who present to an expert private clinic in Tehran over the span of the trial. After allocation to respective groups, the patients will be followed up according to the respective protocol.
Participants/Inclusion and exclusion criteria
A minimum of 239 patients with diffuse toxic goiter who experience recurrence of hyperthyroidism and are referred to an expert private clinic are recruited.
Intervention groups
"Radioactive Iodine Group" and "Methimazole Group".
Under the "Methimazole Group" there are two more groups:
"Conventional Group" and "Long-term" groups.
Main outcome variables
The primary endpoint is relapse of overt hyperthyroidism after methimazole or radioiodine discontinuation. Key secondary endpoints are occurrence of subclinical hyperthyroidism or overt or subclinical hypothyroidism during or after the treatment modality received.

The methimazole arm of the trial is further randomized to either continue methimazole treatment for an additional period to reach a total of 60 to 120 months (the "long-term" group), or discontinue treatment after the conventional period of 18 to 24 months of treatment (the "conventional" group). This randomization is also done through using the Table of Random Digits.
