Hyperthyroidism
Conditions
Brief summary
This study intends to conduct a retrospective and prospective study on children with hyperthyroidism, and it is a non-intervention study to collect information on diagnosis and treatment and long-term follow-up of children with hyperthyroidism. To investigate the clinical characteristics, treatment effect, side effects and remission of hyperthyroidism in children, to analyze the predictive factors for the effect of antithyroid drug treatment, remission and recurrence after drug withdrawal, and to explore the risk factors related to the occurrence of antithyroid drug-related adverse reactions.
Interventions
DRUGMethimazole(MMI)
The initial dose of methimazole was 0.2-0.8 mg/(kg▪d). This dose was subsequently reduced by 25% to 50% and adjusted to maintain euthyroidism, based on the results of serum thyroid hormone testing during follow-up.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Remission of hyperthyroidism in children treated with methimazole. Remission is defined as having clinical and biochemical euthyroidism(FT3, FT4 and TSH are normal) without methimazole treatment for at least 12 months. | 10 years | To analyze the therapeutic effect of methimazole and the predictors of remission of hyperthyroidism after methimazole treatment. |
| Adverse effects of methimazole in the treatment of hyperthyroidism in children. Adverse effects are defined as having neutropenia (absolute neutrophil count< 1500/µL), liver dysfunction (AST or ALT> 60 IU/L), rash, arthralgia, myalgia, et al. | 1 year | Analyze the adverse reaction of methimazole treatment in hyperthyroidism children. Explore the risk factors related to the occurrence of methimazole related adverse reactions. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Relapse of hyperthyroidism in children treated with methimazole. Relapse was defined as having clinical and biochemical hyperthyroidism (FT3 and FT4 increased and TSH decreased) after discontinuation of methimazole. | 10 years | The risk factors of relapse in children with hyperthyroidism treated with MMI were analyzed |
