A great deal of knowledge about eosinophilic lung diseases has been gained in the last few years, but unanswered questions concerning eosinophil biology still remain. It is in this context that this Monograph was developed. Broad in scope, the book bases its approach to the management of eosinophilic lung diseases on a fundamental understanding of eosinophil biology in health and disease. State-of-the-art reviews written by world-leading authorities and up-and-coming stars in the field take the reader on a journey through the different eosinophilic lung diseases. This Monograph will ensure the practicing clinician is better equipped to recognise and treat patients with eosinophilia, as well as appreciate the advances coming in the near future.
