[Fluctuation of symptomatic VAS score during immunotherapy on allergic rhinitis]

To understand the fluctuation of symptomatic visual analogue scale(VAS)score and its reasons during the allergic rhinitis patients treated with single-mite antigen immunotherapy.

Three hundred and seventy six patients with allergic rhinitis were treated with single-mite antigen immunotherapy and their symptoms were evaluated by VAS score and chart, the relative factors which could affect the symptom were followed up.

During the allergic rhinitis patients treated with single-mite antigen immunotherapy, the symptomatic VAS score appeared fluctuation from the 8th to 34th time of therapy. The VAS score increased at the 8 th, 18 th, 22 th, 25 th, 29 th, and 34 th time. Afterwards, it generally decreased to a lowest level of the whole treatment process in the last. The comprehensive analysis implied that the factors resulting in VAS score fluctuation were patients expectation, emotion, socio-economic conditions, living environment, re-contact of allergen and children's unclear complain.

Patients' expectation, emotion, socio-economic conditions, living environment, re-contact of allergen and children's unclear complain can result in symptomatic VAS score fluctuation. It prompts that health education be necessary before the treatment of allergic rhinitis with single-mite antigen immunotherapy.
