[Pollinosis and bronchial asthma: pathogenesis, immunology, clinical aspects]

Rhinoconjunctivitis induced by pollen exposure and bronchial asthma are generally easily recognizable clinically. In asthma a number of differential diagnoses such as ciliary dyskinesia, cystic fibrosis and gastro-oesophageal reflux must be considered. The predominant symptoms are coughing and wheezing. Investigations into the complex nature of mediator release and IgE synthesis have established a predominantly inflammatory pattern of reactions largely responsible for induction and maintenance of bronchial hyperresponsiveness due to both acute and chronic processes. Future therapeutic consequences may be derived from anti-inflammatory strategies. This has already lead to reassessment and upgrading of use of corticosteroids in paediatric asthma.
