This volume provides a current concept of theory and clinical practice of immunopathology and therapy of asthma, comprising extensive and brand new laboratory data on atopy, intrinsic asthma, aspects of autoimmunology, as well as guidelines for allergen avoidance, immunotherapy and - last not least - pharmacological treatment of cosinophilic inflammation.
