[Invasive aspergillosis in two hematological patients]
1Arhus Universitetshospital, haematologisk afdeling B. c.rask@dadlnet.dk
Abstract:
We present two cases of invasive aspergillosis in patients with acute myeloid leukemia. In neutropenic patients with antibiotic resistent fever, without specific symptoms or signs, invasive aspergillosis should be considered. Diagnostic approaches such as X-ray/CT-scan of the thorax and sinuses, relevant cultures and antigen detection should be performed. Due to diagnostic difficulties and the rapid progression of the infection empirical antifungal therapy should be given. During subsequent neutropenic episodes prophylactic antifungal therapy can possibly preempt recurrence.
Insights
Invasive aspergillosis is a serious risk for acute myeloid leukemia patients experiencing neutropenic fever. Early diagnosis and empirical antifungal treatment are crucial for managing this aggressive fungal infection.
Area of Science:
- Mycology
- Hematology
- Infectious Diseases
Background:
- Acute myeloid leukemia (AML) patients often experience neutropenia, increasing susceptibility to opportunistic infections.
- Invasive aspergillosis is a life-threatening fungal infection caused by Aspergillus species.
- Neutropenic fever in AML patients can be challenging to diagnose and manage.
Observation:
- Two cases of invasive aspergillosis in AML patients are presented.
- Patients presented with neutropenic fever and antibiotic resistance without specific symptoms.
- Diagnostic tools included radiography (X-ray/CT scans) of the thorax and sinuses, cultures, and antigen detection.
Findings:
- Invasive aspergillosis should be strongly considered in neutropenic patients with unexplained fever.
- Diagnostic challenges and rapid disease progression necessitate prompt intervention.
- Empirical antifungal therapy is recommended due to diagnostic difficulties and rapid progression.
Implications:
- Early consideration of invasive aspergillosis improves patient outcomes in AML.
- Diagnostic imaging and laboratory tests are essential for timely identification.
- Prophylactic antifungal therapy may prevent recurrent infections during subsequent neutropenic episodes.
