Asthma bronchiale

M. Schmidt

Bronchial asthma, with a prevalence in Germany of 5% among adults and 10% among children, remains a frequent disease. Newer cell biological data show a separate regulation of the allergy (interleukin 4, IL-4, pathway) and of the eosinophilic inflammation in asthma (IL-5 pathway). Both conditions require a therapeutic approach. To prevent irreversible bronchial remodeling, early diagnosis and targeted therapy are decisive. Bronchial asthma is regarded as evident when the paroxysmal character of the disease is confirmed and an-at least intermittent-obstructive ventilation disorder is apparent which responds well to short-acting beta2-adrenergic agents. Current asthma treatment has been assured in many studies (evidence level A) and is based on therapy in stages which classifies therapeutic measures depending on four grades of severity. Accordingly, most patients are largely without complaints, and nocturnal attacks are now rare. New medications are intended to overcome any remaining therapeutic weak points. Antileukotrienes and anti-IgE antibodies can contribute to reducing the necessary corticosteroids. Pharmaceutical agents that intervene in the IL-4 or IL-5 regulation or prevent remodeling are being developed.
