Official title:
Evaluation of Clinical and Immunological Parameters in Children Treated With Subcutaneous Immunotherapy Towards Pollen - a Controlled Study

Study type | Interventional |
The objective is to prospectively explore associations between immunological parameters in blood and clinical effect of subcutaneous immunotherapy (SCIT) in children with severe allergy towards pollen. Half of the children will receive SCIT while the other half will start SCIT after the study is finished. Clinical evaluations of symptoms and an immunological survey will be performed before start of SCIT and after one year of treatment. Some of the immunological parameters will also be checked after 6 months of treatment

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Response to a Conjunctival Allergen Challenge | Change in the dose of allergen needed to elicit a clinical response following ocular administration of the allergen | Before treatment and after 12,24 and 36 months | |
Secondary | PADQLQ (pediatric allergic disease quality of life questionnaire) in Swedish LILA | Includes 26 questions regarding allergic symptoms scored from 0 (no symptoms) to 6 (very severe symptoms) during pollen season. Difference in change of total score between intervention and control group will be assessed | Baseline and after 12,24 and 36 months of immunotherapy | |
Secondary | Questionnaire regarding use of pharmacologic treatment for allergy and asthma during pollen season | Frequency of use of 8 different drugs will be scored from 0(never) to 5 (daily). Difference in change of total score between intervention and control group will be assessed | Baseline and after 12,24 and 36 months of immunotherapy | |
Secondary | Questionnaire regarding quality of life | DISABKIDS, a european quality of life questionnaire used in children with chronic diseases consisting of 37 quality of life questions with answers rated from ever (0=best) to never (5= worst). Difference in change of total score between intervention and control group will be assessed | Baseline and after 12,24 and 36 months of immunotherapy | |
Secondary | Change in level of IgE-antibodies | Difference in change between intervention and control group will be assessed | Baseline and after 12,24 and 36 months of immunotherapy | |
Secondary | Change in level of IgG-antibodies | Difference in change between intervention and control group will be assessed | Baseline and after 12,24 and 36 months of immunotherapy | |
Secondary | Change in level of IgG4-antibodies | Difference in change between intervention and control group will be assessed | Baseline and after 12,24 and 36 months of immunotherapy |
