[Conservative treatment of hyperthyroidism (author's transl)]

Area of Science:

• Endocrinology
• Pharmacology

Context:

• Hyperthyroidism is a common endocrine disorder often managed with antithyroid medications.
• Long-term outcomes and recurrence rates after antithyroid drug (ATD) therapy cessation are critical for patient management.

Purpose:

• To evaluate the recurrence rate of hyperthyroidism after discontinuing antithyroid medication.
• To identify predictors of hyperthyroid recurrence following treatment cessation.

Summary:

• This study followed 158 hyperthyroid patients treated with antithyroid drugs for 3-60 months.
• Recurrence was observed in 55.7% of patients, with over 50% occurring within 3 months and 80% within a year post-treatment.
• No correlation was found between treatment duration and recurrence rate or time.
• Predictors of recurrence included nodular/large goiters, severe symptoms, delayed euthyroidism, and persistent sweating despite treatment.

Impact:

• Identifies key clinical factors associated with a higher risk of hyperthyroidism recurrence.
• Informs clinical decision-making regarding treatment duration and patient monitoring post-antithyroid therapy.
• Highlights the need for vigilant follow-up in patients with specific risk factors to prevent or manage recurrent hyperthyroidism.
