Comparison of Perennial and Preseasonal Subcutaneous Immunotherapy - Full Text View

Purpose

Specific immunotherapy, which involves the administration of allergic extracts to patients with symptoms of allergic disorder, is the leading therapeutical tool of modern allergology. According to the latest studies immunotherapy not only reduces symptoms' severity but also may modify the course of allergic disease by reducing the risk of new sensitisations and development of more advanced stages of the disease.It has been hypothesized basing on clinical observation that perennial immunotherapy is more effective and safer in comparison to preseasonal immunotherapy. The aim of the study was to compare the effect of perennial and preseasonal immunotherapy on rhinoconjunctivitis symptoms and safety of both treatments.

Primary Outcome Measures:

difference between preseasonal and perennial immunotherapy in area under curve of combined symptom medication score during 1st year of immunotherapy [ Time Frame: up to 3 months ] [ Designated as safety issue: No ]
combined symptom medication score was calculated as a sum of rhinoconjunctivitis symptoms and use of rescue medications during pollen season
difference between preseasonal and perennial immunotherapy in area under curve of combined symptom medication score during 2nd year of immunotherapy [ Time Frame: up to 3 months ] [ Designated as safety issue: No ]
combined symptom medication score was calculated as a sum of rhinoconjunctivitis symptoms and use of rescue medications during pollen season
difference between preseasonal and perennial immunotherapy in area under curve of combined symptom medication score during 3rd year of immunotherapy [ Time Frame: up to 3 months ] [ Designated as safety issue: No ]
combined symptom medication score was calculated as a sum of rhinoconjunctivitis symptoms and use of rescue medications during pollen season

Secondary Outcome Measures:

frequency of adverse reactions during immunotherapy [ Time Frame: up to 3 years of immunotherapy ] [ Designated as safety issue: Yes ]
type of adverse reactions [ Time Frame: up to 3 years of immunotherapy ] [ Designated as safety issue: Yes ]
the differences from baseline in mean daily rhinoconjunctivitis symptoms score [ Time Frame: up to 3 months/4 years ] [ Designated as safety issue: No ]
the differences between study groups in mean daily rhinoconjunctivitis symptoms score [ Time Frame: up to 3 months/4 years ] [ Designated as safety issue: No ]
the differences from baseline in combined symptom medication score [ Time Frame: up to 3 months/4 years ] [ Designated as safety issue: No ]
the differences from baseline a in serum level of sIgG4 [ Time Frame: the peak of each pollen season (June) during 4 years of study ] [ Designated as safety issue: No ]
the differences between study groups in combined symptom medication score [ Time Frame: up to 3 months/4 years ] [ Designated as safety issue: No ]
the differences between study groups in serum level of sIgG4 [ Time Frame: up to 3 months/4 years ] [ Designated as safety issue: No ]
