This study was a prospective follow-up study of newly diagnosed and relapsed Graves' disease patients in the Endocrinology Clinic of the First Affiliated Hospital of China Medical University. The following aspects will be studied: 1. Through the prospective follow-up study of GD patients, we will get the relapse rate and remission rate of GD patients treated with drugs, explore the risk factors of GD patients relapsing after drug treatment, and make GD relapse risk prediction software; 2. To compare the effects of high dose and low dose methimazole on the remission rate, liver side effects, leukopenia and other adverse drug reactions, and to summarize the incidence and risk factors of liver side effects, leukopenia and other adverse drug reactions caused by drug treatment; 3. To investigate the sensitivity and specificity of TRAb in the diagnosis of GD in China and its role in predicting recurrence; 4. After taking ATD, the serum alkaline phosphatase of GD patients will increase first and then decrease. This study will focus on analyzing the dynamic changes of this index before and after methimazole treatment, and analyze the relationship between it and thyroid function index.
Study Type
OBSERVATIONAL
Enrollment
1,000
Determine the enrolled GD patients and adjust the dosage of methimazole according to the 2016 American Thyroid Association guidelines. Conduct thyroid function, liver function, TRAb, and blood routine tests during outpatient follow-up to observe the treatment effect and provide medication guidance.

RECRUITINGRelapse and remission of Graves' disease in adult treated with methimazole.
Relapse was defined as having clinical and biochemical hyperthyroidism (FT3 and FT4 increased and TSH decreased) after discontinuation of methimazole. Remission is defined as having clinical and biochemical euthyroidism(FT3, FT4 and TSH are normal) without methimazole treatment for at least 12 months. Through the prospective follow-up study of GD patients, we will get the relapse rate and remission rate of GD patients treated with drugs, explore the risk factors of GD patients relapsing after drug treatment, and make GD relapse risk prediction software.
Time frame: 30 years
Adverse effects of methimazole in the treatment of Graves' disease in adult.
Adverse effects are defined as having neutropenia (absolute neutrophil count\< 1800/µL), liver dysfunction (AST or ALT\> 60 IU/L), rash, arthralgia, myalgia, et al. To compare the effects of high dose and low dose methimazole on the remission rate, liver side effects, leukopenia and other adverse drug reactions, and to summarize the incidence and risk factors of liver side effects, leukopenia and other adverse drug reactions caused by drug treatment
Time frame: 30 years
Thyrotropin receptor antibody(TRAb)
To investigate the sensitivity and specificity of the thyrotropin receptor antibody(TRAb) in the diagnosis of GD in China and its role in predicting recurrence
Time frame: 30 years
The serum alkaline phosphatase
After taking ATD, the serum alkaline phosphatase of GD patients will increase first and then decrease. This study will focus on analyzing the dynamic changes of this index before and after methimazole treatment, and analyze the relationship between it and thyroid function index
