RT Journal Article SR Electronic T1 Successful treatment of allergic bronchopulmonary aspergillosis with recombinant anti-IgE antibody JF Thorax JO Thorax FD BMJ Publishing Group Ltd and British Thoracic Society SP 276 OP 277 DO 10.1136/thx.2004.035519 VO 62 IS 3 A1 Cornelis K van der Ent A1 Hans Hoekstra A1 Ger T Rijkers YR 2007 UL http://thorax.bmj.com/content/62/3/276.1.abstract AB Allergic bronchopulmonary aspergillosis (ABPA) can cause severe worsening of the respiratory condition in patients with cystic fibrosis. Treatment can result in steroid dependency and serious adverse events. A dramatic and rapid improvement of respiratory symptoms and lung function after a single dose of anti-IgE antibody (omalizumab) in a 12-year-old girl with cystic fibrosis and ABPA is described. This is the first report of this experimental treatment. It suggests an important role for IgE in the pathogenesis of ABPA and offers new therapeutic possibilities.
