High-dose methylprednisolone-induced dramatic maturation of granulocytes in idiopathic chronic neutropenia
Abstract:
Idiopathic chronic neutropenia is characterized by a variable pattern of age at the onset of neutropenia, neutrophil counts, maturational arrest at the promyelocyte/myelocyte stage in the bone marrow, and recurrent pyogenic infections without any underlying disease or drug administration. There have been reports of lack of response to conventional-dose steroid therapy, but in recent studies it has been shown that high-dose corticosteroids are effective in several neutropenic states. Here we report an apparent response to high-dose methylprednisolone in a patient with idiopathic chronic neutropenia.
Insights
Idiopathic chronic neutropenia may respond to high-dose corticosteroids. This study reports a case of chronic neutropenia showing improvement with high-dose methylprednisolone treatment.
Area of Science:
- Hematology
- Immunology
Background:
- Idiopathic chronic neutropenia presents with low neutrophil counts and increased infection risk.
- Conventional steroid doses are often ineffective for this condition.
