Summary
Antithyroid drugs can cause agranulocytosis, a dangerous drop in white blood cells, in patients with thyrotoxicosis. Early recognition and treatment with granulocyte colony-stimulating factor can reverse this potentially lethal condition.
Area of Science:
- Endocrinology
- Hematology
Background:
- Thyrotoxicosis is a prevalent endocrine disorder.
- Antithyroid drug therapy is a primary treatment, particularly for women of reproductive age.
- Agranulocytosis is a severe adverse effect of antithyroid medications.
Purpose of the Study:
- To report two cases of antithyroid drug-induced agranulocytosis.
- To highlight the clinical presentation and management of this condition.
Main Methods:
- Case report of two patients presenting with fever and severe neutropenia.
- Treatment with granulocyte colony-stimulating factor (G-CSF).
Main Results:
- Both patients exhibited fever and severe neutropenia.
- G-CSF administration led to significant improvement in white blood cell counts and symptoms.
Conclusions:
- Antithyroid drug-induced agranulocytosis is a serious, potentially fatal complication.
- Early diagnosis and prompt G-CSF treatment are crucial for complete recovery.
