Aspergillus infection is associated with a high mortality rate in immunocompromised hosts; more effective drugs for this infection are needed. Oral itraconazole has been studied in neutropenic fungus-infected patients. Using a novel formulation (intravenous) of itraconazole, we successfully treated severe necrotizing pneumonias due to Aspergillus species occurring during a postchemotherapy prol...

Recurrent infections are a consequence of a series of genetic diseases characterized by deficiency in the immunological response. One of these diseases is the agammaglobulinemia, which is characterized by the basic defect in the maturation of lymphocytes B. The carrier of this kind of immunodeficiency, which is linked to the X (XLA) chromosome, has had primary pneumonias that have evolved into ...
