RT Journal Article SR Electronic T1 Severe refractory asthma: an update JF European Respiratory Review JO EUROPEAN RESPIRATORY REVIEW FD European Respiratory Society SP 227 OP 235 DO 10.1183/09059180.00001913 VO 22 IS 129 A1 Reinier R.L. Wener A1 Elisabeth H. Bel YR 2013 UL http://err.ersjournals.com/content/22/129/227.abstract AB Asthma is a heterogeneous disease in which adequate asthma control cannot be achieved in a substantial proportion despite currently available treatment possibilities. This subgroup has been defined as “severe refractory” asthma. Over the past years considerable progress has been made regarding a more exact definition of severe refractory asthma. A systematic approach to evaluate the asthma patient has been postulated. Further detailed classification into distinct phenotypes is ongoing to target the right treatment to the right patient. And, new therapeutic targeted treatment options are currently in development to provide possible new targets to improve disease state, symptoms and quality of life. This review will provide an update on the latest advancements with regard to all these domains.
