[Fatal cerebral aspergillosis in acute megakaryoblastic leukemia]
Abstract:
A 13 year-old girl was diagnosed as having acute megakaryoblastic leukemia. A serious infectious syndrome appeared during the chemotherapy, not improved by broad spectrum antibiotic therapy. A pulmonary aspergillosis was diagnosed one month later by a second bronchoalveolar lavage. A treatment with Itraconazole, a new antifungal triazole, was started. Despite this treatment, the child died after 3 days. Death was due to multiple aspergillus abscesses disseminated in the brain leading to coma and transtentorial herniation. Autopsy confirmed the cerebral aspergillus abscesses and showed also the dramatic dissemination of aspergillosis in the body. Diagnosis and treatment to aspergillosis in immunosuppressed patients should be made early to improve prognosis.
Insights
A child with acute megakaryoblastic leukemia developed invasive pulmonary aspergillosis during chemotherapy. Despite antifungal treatment, disseminated aspergillosis led to a fatal outcome, highlighting the need for early diagnosis and intervention in immunocompromised patients.
Area of Science:
- Hematology
- Mycology
- Infectious Diseases
Background:
- Acute megakaryoblastic leukemia is a rare and aggressive hematologic malignancy.
- Immunosuppression during chemotherapy increases the risk of opportunistic infections, such as invasive fungal infections.
- Aspergillosis, a serious fungal infection caused by Aspergillus species, poses a significant threat to immunocompromised individuals.
Observation:
- A 13-year-old girl with acute megakaryoblastic leukemia developed a severe infectious syndrome during chemotherapy.
- Initial broad-spectrum antibiotic therapy was ineffective.
- Pulmonary aspergillosis was diagnosed via bronchoalveolar lavage.
- The patient received Itraconazole, a triazole antifungal agent.
Findings:
- Despite Itraconazole treatment, the patient's condition rapidly deteriorated.
- Death occurred three days after initiating antifungal therapy.
- Autopsy revealed widespread Aspergillus abscesses in the brain and other organs, confirming disseminated aspergillosis.
- Cerebral aspergillosis led to coma and transtentorial herniation.
Implications:
- Early and accurate diagnosis of invasive aspergillosis in immunocompromised patients is critical.
- Prompt initiation of effective antifungal therapy is essential for improving patient outcomes.
- This case underscores the challenges in managing invasive fungal infections in patients with hematologic malignancies.
