[Nasal provocation tests in the diagnosis of allergic rhinitis].
Allergic rhinitis is a frequent immunological disease affecting about 10-25% of the total population. The pathogenesis of allergic rhinitis is presumed to involve an IgE-mediated mechanism. Careful patient history, together with the skin prick test or RAST, usually allows an easy diagnosis of allergic rhinitis. In other cases it may be necessary to confirm diagnosis by the nasal provocation test. Different methods of provocation and measurement of nasal responses have been used in recent years. Scoring of the severity of clinical symptoms is too subjective to be clinically useful and should therefore be supplemented by one of the objective measurement techniques, such as anterior rhinomanometry. Additional analysis of nasal cytologic findings and determination of biomarkers in nasal secretions can be a critical tool in the evaluation of pathophisiology of allergic rhinitis. We critically discuss indications and contraindications for nasal challenges and review current techniques of provocation. We also provide various methods of assessment of nasal responses. The included examples of nasal provocation tests protocols may be helpful in introducing nasal provocation tests into everyday clinical practice.
