Effective acute desensitization for immediate-type hypersensitivity to human granulocyte-monocyte colony stimulating
Summary
Acute desensitization successfully managed hypersensitivity to granulocyte-monocyte colony stimulating factor (GM-CSF) in a patient with chronic mucocutaneous candidiasis. This approach allows continued GM-CSF treatment when drug hypersensitivity occurs.
Area of Science:
- Immunology
- Hematology
- Pharmacology
Background:
- Granulocyte-monocyte colony stimulating factor (GM-CSF) is crucial for treating life-threatening neutropenias.
- Hypersensitivity reactions to GM-CSF can necessitate treatment cessation.
- Acute desensitization offers an alternative management strategy for drug hypersensitivity.
Observation:
- A patient with chronic mucocutaneous candidiasis developed anaphylaxis to GM-CSF and G-CSF despite antihistamine and corticosteroid premedication.
- Skin prick tests confirmed hypersensitivity to both GM-CSF and G-CSF.
- Acute desensitization to GM-CSF was initiated using a penicillin desensitization protocol.
Findings:
- The patient tolerated GM-CSF desensitization well, enabling resumption of treatment.
- GM-CSF therapy was safely continued for 30 months, resolving candidal infections.
- Post-desensitization skin tests showed a significantly reduced response to GM-CSF.
Implications:
- Acute desensitization is a viable option for managing GM-CSF hypersensitivity.
- This technique is vital for patients for whom GM-CSF is irreplaceable.
- It ensures treatment continuity for severe conditions like chronic mucocutaneous candidiasis.
