Sociodemographic parameters (e.g., gender, date of birth) and medical parameters (diagnosis, therapy) are entered in the register. In addition, data on lung function, laboratory values (IgE and eosinophil granulocytes), asthma control (symptoms, nocturnal awakenings, on-demand medication, exacerbations), smoking status, and concomitant therapy (inhalable corticosteroids, bronchodilators, and systemic steroids) are collected. This information will be collected at the baseline visit, and then once a year at a follow up visit, for fifteen years. Participants will be assigned a unique study ID to protect the confidentiality of their personal health care information. Personal data and register data are on separate servers and thus meet the requirements of data protection. The primary purpose is to establish a clinical registry for patients with severe asthma. The number of patients with severe asthma at a single center or practice is usually small, so several centers (clinics and practices) in Germany have joined together to form the German Asthma Net e.V. to optimize the diagnostic evaluation and treatment of patients with severe asthma.
