[Management of hemoptysis in invasive pulmonary aspergillosis]

Invasive pulmonary aspergillosis is an opportunistic infection occurring in a background of severe immune depression. The majority of cases occur in patients who have malignant hematologic disease, particularly during chemotherapy induction or consolidations phases for acute non-lymphocytic leukemia. The principal risk factors are profound (PN < 500 per mm3) and prolonged (very high risk beyond 20 days) neutropenia, perturbed phagocyte function and cellular immune deficiency (AIDS, immunosuppressive treatment in organ and bone marrow recipients). Clinically, invasive pulmonary aspergillosis presents as acute non-specific pneumonia with cough, chest pain and fever. The severe infection rapidly becomes life-threatening. The development of massive hemoptysis is a major risk. We report four cases of invasive pulmonary aspergillosis in patients who had hemoptysis. All four patients developed non-specific pneumonia resistant to broad-spectrum antibiotics during post-chemotherapy aplasia. Computed tomography of the thorax and bronchoscopy with bronchoalveolar lavage was performed due to the occurrence of hemoptysis. In the first two cases, the patients were recovering from aplasia. The thoracic CT scan showed evidence of a cavitating mass with peripheral vessels. Bronchoscopy findings suggested mucosal lesions. The patients were managed surgically. Pathology confirmed the diagnosis of invasive pulmonary aspergillosis with the presence of ischemic necrosis of the pulmonary parenchyma harboring numerous aspergillus filaments. Outcome was favorable and chemotherapy was re-initiated in one case. These two patient died from their hematological disease a few months later. The other two patients remained in aplasia. A CT of the thorax showed multifocal infiltration with vascular contact. Bronchoscopy was again suggestive. One patient developed massive hemoptysis with respiratory distress. Embolization was performed but the patient died two days after onset of hemoptysis. In the last case, embolization was successful and outcome was favorable enabling a bone marrow allograft; the patient died a few months later from the hematological disease. The potential gravity of hemoptysis in the course of invasive pulmonary aspergillosis should lead to early treatment with emergency CT scan and, if possible, bronchoscopy with bronchoalveolar lavage to establish the therapeutic strategy based on surgical excision or embolization of the pulmonary or bronchial arteries.
