Safety and efficacy of tree pollen specific immunotherapy on the ultrarush administration schedule method using purethal trees.
BACKGROUND
Specific immunotherapy (SIT) with an ultrarush administration schedule with Purethal for tree pollen allergens has been evaluated to assess its efficacy and safety.


METHODS
The study group consisted of 22 patients with symptoms of allergic rhinitis and confirmed allergy to tree pollens. Patients were randomized and given an administration schedule of either ultrarush therapy or conventional preseasonal SIT. Treatment was performed during three consecutive years.


RESULTS
After three years of treatment, a similar reduction in nasal symptoms was observed; according to the visual analog scale, there was a decrease from 3.991 ± 0.804 points to 1.634 ± 0.540 in the ultrarush group and from 3.845 ± 0.265 to 1.501 ± 0.418 in the group desensitized using the conventional method (P > 0.05). There was also a comparable reduction in the use of relief drugs during pollen season and an increase in the serum concentration of IgG4 to tree pollens. No significant differences in the safety profile were observed.


CONCLUSIONS
An administration schedule of ultrarush SIT with Purethal Trees is a safe treatment in preliminary observations. This therapy is comparable with conventional administration of SIT in the field of efficacy and safety.
