Retrospective Data Collection Based on Patient Records and Questionaire Based Data of Therapy Results of Allergen-specific Immunotherapy With Pollinex Quattro With Tree and/or Gras Pollen Extracts and Their Mixtures

Primary goal of this non-interventional study is to evaluate the change in level of allergen-specific IgE (EAST class) after allergen-specific immunotherapy with Pollinex Quattro with tree and/or grass pollen extracts and their mixtures under medial routine at adults with tree- and/or grass-medicated pollinosis.

In this non-interventional study, the change in level of allergen-specific IgE before and after 3 or more years of allergen-specific immunotherapy with Pollinex Quattro in a patient population with tree and/or grass pollen induced pollinosis and/or asthma will be analyzed. In addition, the change in medication usage, asthma status for asthmatic patients after 3, 4 or 5 years of allergen specific immunotherapy will be evaluated. Furthermore, patients will be asked for their change in quality of life after therapy end.
