[Hypereosinophilic asthma].
Hypereosinophilic asthma (defined by blood eosinophils > 1 G/L, especially > 1.5 G/L) may be solitary (and often difficult to treat), or a manifestation of a hypereosinophilic disorder of determined cause (parasitic, iatrogenic, allergic bronchopulmonary aspergillosis) or idiopathic (idiopathic chronic eosinophilic pneumonia, Churg-Strauss syndrome, idiopathic hypereosinophilic syndrome). In addition to etiologic treatment when available long term corticosteroids are necessary in a majority of patients.
