Summary
Acute respiratory failure occurred in a child after intrathecal methotrexate (MTX) for central nervous system (CNS) leukemia prophylaxis. This rare event may stem from MTX
Area of Science:
- Pediatric Oncology
- Neuro-oncology
- Pharmacology
Background:
- Acute lymphoblastic leukemia (ALL) treatment often involves central nervous system (CNS) prophylaxis.
- Intrathecal methotrexate (MTX) is a common method for CNS leukemia prophylaxis.
Observation:
- A 3-year-old girl with ALL developed acute respiratory failure post-intrathecal MTX administration.
- The patient's condition suggests a potential adverse reaction to the treatment.
Findings:
- The respiratory failure could be linked to acute metabolic or direct neurotoxic effects of MTX.
- The precise mechanism causing this complication remains undetermined.
Implications:
- This case highlights a rare but serious potential adverse event associated with intrathecal MTX.
- Further investigation may be warranted to understand MTX neurotoxicity in pediatric patients.
- Awareness of this complication is crucial for clinicians managing pediatric CNS leukemia.
