[Allergic bronchopulmonary aspergillosis].

Allergic bronchopulmonary aspergillosis (ABPA) is an immunologic bronchopulmonary inflammation due to an immune response of the lower respiratory tract against Aspergillus fumigatus. The major clinical features of ABPA include asthma, recurrent pulmonary infiltrates, immediate wheal and flare skin reactivity to A. fumigatus, elevated total serum IgE levels, detectable serum precipitating antibodies to A. fumigatus, peripheral blood eosinophilia, elevated levels of Aspergillus-specific serum IgE and central bronchiectasis with normal distal structures. The diagnosis of ABPA should be considered in asthmatics of all ages. Evolution of the disease comprises five stages from the acute to the fibrotic stage including pulmonary fibrosis and respiratory insufficiency. The goals of ABPA treatment are to control patient's asthma and prevent exacerbations of ABPA. During the acute stage, prednisone should be administered. Antifungals agents (itraconazole) may be useful to prevent exacerbations of the disease.
