RESUMEN
BACKGROUND: Although allergic diseases are among the most important health disorders, allergology is not anchored as an independent subject in the clinical part of medical studies in Germany. OBJECTIVE: As all universities and institutes face the same challenge, the aim of our project was to establish exemplary coordination and networking of education in allergology at one location in agreement with all involved departments and institutes. Particularly, Comprehensive Allergy Centers (CAC) offer an established infrastructure via which the revised allergology education program can be transferred to other universities. MATERIALS AND METHODS: After an extensive inventory of the current allergological curriculum at the University Medical Center Göttingen, a new teaching concept was developed in interdisciplinary consensus, supplemented by first-time provision of additional digital contents ("blended learning"), and finally evaluated. RESULTS: Initially, we observed a high level of fragmentation in the teaching of allergology in the clinical study sections of human medicine, with no coordination between the 12 clinical departments/institutes involved and no coherent framework for the specific learning content. Within the established structure of the interdisciplinary CAC, we revised, coordinated, and defined key areas for improved student education in clinical allergology. The allocation of new interactive learning elements as well as supplementary materials for self-studies was welcomed by the students and positively evaluated. A survey among students after completing the former vs. current curricula showed significant improvements in achieving the desired educational objectives.

BACKGROUND: Fungal spores are ubiquitous allergens. Severe forms of asthma are particularly highly associated with fungal sensitization. National and international asthma guidelines recommend the implementation of allergen immunotherapy if indicated. Thus, detection and treatment of relevant allergies are key components of primary care of these patients. OBJECTIVES: The aims of the study were (i) to investigate trends in the prevalence of sensitization to twelve fungi in central Germany over the last 20 years and (ii) to dissect specific sensitization patterns among the 3 most important fungi: Aspergillus, Alternaria, and Cladosporium. METHODS: This single-center study evaluated skin prick test (SPT) results of 3,358 patients with suspected airway allergies over a period of 20 years (1998-2017). RESULTS: While 19.2% of all study patients had positive test results to at least 1 of the 3 fungi (Alternaria, Aspergillus, or Cladosporium) in the first study decade, this rate increased to 22.5% in the second decade. Slight increases in sensitization rates to almost all fungi were observed over the 20-year period. In the last decade, polysensitization to Alternaria, Aspergillus, and Cladosporium increased significantly. Sensitization to fungi is age-dependent and peaks in the age-group of 21-40 years during the second decade. CONCLUSION: Fungi are relevant allergens for perennial and seasonal allergy symptoms. We currently recommend including Aspergillus, Alternaria, and Cladosporium in the standard series of SPTs for airway allergies.

BACKGROUND: Sensitization rates to aeroallergens are rising worldwide. The prevalence is increasing, especially in Western countries. We aimed to investigate (1) sensitization rates and (2) cross-sensitization patterns in skin prick tests (SPTs) for the most relevant inhaled allergens in central Germany over 20 years, adjusted for regional pollen counts. PATIENTS AND METHODS: This monocentric study evaluated SPTs for tree pollen, grass pollen and house dust mites (HDMs) in 4,315 patients (including children) with suspected airway allergies, from 1998-2017. RESULTS: Sensitization rates to almost all aeroallergens have increased significantly over time, without relevant changes in regional pollen counts. Current sensitization rates in all our symptomatic patients were highest for grass (55.3 %) and rye pollen (59.6 %), with most pronounced increases in HDM sensitization over time (from 37.8 % to the current figure of 50.1 %). However, a low but consistent proportion of tree-sensitized patients (3.6-7.8 %) showed isolated positive SPTs to alder and/or hazel pollen without sensitization to birch pollen. CONCLUSIONS: We demonstrate a significant rise in the total number of sensitized patients as well as increases in cross-sensitization between closely related allergens. Individuals with unusual mono-sensitization profiles to common inhaled allergens should be studied in more detail, since these patients are currently excluded from clinical trials for allergen immunotherapy.

INTRODUCTION: The prevalence of airway allergies in Europe has increased from 23% to 31% in recent years. 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.
