Methimazole-Induced Agranulocytosis and Quick Recovery with G-CSF
Hematology (Amsterdam, Netherlands)
|July 16, 2016
Summary
Methimazole, a hyperthyroidism drug, can cause agranulocytosis. Granulocyte colony-stimulating factor (G-CSF) effectively restored granulocyte counts in a patient, suggesting its use in treating this condition.
Area of Science:
- Endocrinology
- Hematology
Background:
- Hyperthyroidism is commonly treated with methimazole.
- Methimazole can lead to serious side effects like agranulocytosis, a severe drop in white blood cells.
- Agranulocytosis increases the risk of life-threatening infections.
Purpose of the Study:
- To report a case of methimazole-induced agranulocytosis.
- To evaluate the efficacy of recombinant human granulocyte colony-stimulating factor (G-CSF) in treating this condition.
Main Methods:
- A patient with hyperthyroidism developed agranulocytosis during methimazole therapy.
- Methimazole was discontinued.
- Treatment with broad-spectrum antibiotics and G-CSF was initiated.
Main Results:
- The patient's granulocyte count normalized after the fourth dose of G-CSF.
- G-CSF treatment was associated with a rapid recovery of neutrophil levels.
Conclusions:
- Recombinant human granulocyte colony-stimulating factor (G-CSF) appears effective in managing methimazole-induced agranulocytosis.
- G-CSF may reduce infection risk and severity in these patients.
- Consideration of G-CSF as a standard therapy for methimazole-induced agranulocytosis is warranted.

4.2K
Common myeloid progenitors (CMPs) are oligopotent cells that can differentiate into granulocytes and macrophages. Granulocytes and macrophages are essential for protecting the body against bacterial, viral, or fungal infections. They migrate from the bone marrow into the circulating blood to reach specific tissue sites where they differentiate and help in immune surveillance. However, they survive only for a few days and must be continuously made available to the organism to maintain a robust...

01:29Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents
649
Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel...

01:20Myasthenia Gravis: Overview and Treatment
3.3K
Myasthenia gravis is a neuromuscular transmission disorder characterized by weakness and increased fatigability of skeletal muscles. It is an autoimmune disease affecting approximately one in 2000 people, where antibodies against the α1 subunit of nicotinic acetylcholine receptors are produced.
These antibodies interfere with the function of the nicotinic receptors in three ways: by binding to the receptor and disrupting acetylcholine binding; by causing cross-linking of receptors which...
