[Invasive aspergillosis in intensive care].

Invasive pulmonary aspergilloses occur in patients with antineoplasic chemotherapy, mainly when associated with a prolonged neutropenia, in transplanted patients with continuous corticotherapy and less frequently in immunocompetent surgical patients. The clinical features are those of an acute infective pneumonia, not responding to antibiotherapy. Radiologic signs are often non specific. Diagnosis is obtained with bronchoalveolar lavage in which Aspergillus is found both at direct examination and in culture. Serological tests are of little interest for the diagnosis of invasive aspergillosis. Extrapulmonary locations such as sinusitis, cutaneous or brain abscesses occur in 20% of cases. The gold standard of treatment is intravenous amphotericin B which elicits an acute reaction often followed by a nephrotoxic effect which can be decreased by fluid loading with saline. Oral itraconazole administration can follow the initial treatment with amphotericin B. The mortality rate remains high and an early diagnosis and an appropriate treatment are essential.
