Changes in Specific Immunoglobulin and Blood Basophil Activity During Subcutaneous Immunotherapy in Allergic Rhinitis

The trial is randomized prospective study to examine the effects of subcutaneous immunotherapy on the adaptive immune system. The trial includes 30 participants randomized to treatment or control group. The effect measures are changes in the basophil activity and biology as well as changes in plasma cells during and after treatment. Clinical outcome is assessed by QoL questionnaires and clinical testing. Hypotheses: * changes in plasma cells correlate to changes in immunoglobulins and effector cell responses * the reduction of inflammation due to SCIT has influence on the effector cell responses * changes in paraclinical measurements can be related to clinical findings
