Introduction:
Invasive pulmonary aspergillosis is a serious complication in hematology.
Aim:
Describe the prevalence, diagnostic aspects, therapeutic modalities, and evolution of the IPA cases occurring in patients with acute leukemia.
Methods:
Our study was retrospective including patients with acute leukemia who developed invasive pulmonary aspergillosis during the period January 2009 and December 2020 at the hematology department in south Tunisia. The IPA was defined in three levels of probability according to the criteria of the EORTC / MSG 2019.
Results:
We collected 127 patients who presented with Invasive pulmonary aspergillosis. Sixty-three percent of our patients had acute myeloid leukemia. The diagnosis of invasive pulmonary aspergillosis was during the induction course in 76% of cases. Twenty-seven of our patients had chest pain. The chest Computed tomography (CT) scan showed the Halo sign in 89% of cases. The Aspergillus galactomannan antigen was positive in 38% of cases. Extrapulmonary aspergillosis involvement was noted in 18% of cases: IPA was possible and probable respectively in 59% and 41% of cases. All patients treated with Voriconazole with a favorable response in 54% of cases. The mortality rate was 46%. The overall survival at week 12 was 56%.
Conclusion:
The morbidity and mortality of patients who developed invasive pulmonary aspergillosis with acute leukemia in our series were high. We need to improve our strategy for early diagnosis and management.

Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes.
