Polysensitization is associated with the development and severity of relevant allergies, particularly allergic asthma.Objective: We investigated age- and sex-dependent monosensitization and polysensitization profiles as well as patterns of sensitization using skin prick test (SPT) reactivity to the most common aeroallergens.Patients and Methods: From 1998 to 2017, SPTs were retrospectively analyzed in 2886 symptomatic patients, referred to the University Medical Center Göttingen, located in central Germany. The major aeroallergen groups early flowering tree pollen, grass pollen, and house dust mites were evaluated in this study. Wheal diameters ≥ 2 mm were considered positive during the entire study period.Results: Polysensitization to the most common aeroallergen groups increased significantly over 20 years. Boys and young men displayed the most remarkable rise in total sensitization rates in our study group over time.Discussion: Our patient-based study demonstrates a continuing increase in polysensitization rates over the last 20 years, with boys and young men being most frequently affected. Our data—without being a population-based study—suggest a scenario with climbing rates of allergic rhinitis and asthma.Keywords: aeroallergens, polysensitization, sensitization pattern, skin prick test
