Veröffentlichung Management of patients with seasonal allergic rhinitis: Diagnostic consideration of sensitization to non-frequent pollen allergens(2021) Balakirski, Galina; Höflich, Conny; Mücke, Hans-Guido; Straff, WolfgangVeröffentlichung Perspektiven für ein bundesweites Pollenmonitoring in Deutschland - fachübergreifender Arbeitskreis "Bundesweites Pollenmonitoring"(2020) Baeker, Regine; Bergmann, Karl-Christian; Buters, Jeroen; Höflich, Conny; Mücke, Hans-Guido; Straff, WolfgangAllergene Pollen sind natürliche, biologische luftgetragene Partikel und der Hauptauslöser allergischer Atemwegserkrankungen. Die Messung allergener Pollen ist Voraussetzung für die gesundheitliche Vorsorge und zeigt Veränderungen im Pollenspektrum an, wie sie zum Beispiel im Rahmen des Klimawandels zu erwarten sind. Das in Deutschland einzige bundesweite Pollenmessnetz wird durch die Stiftung Deutscher Polleninformationsdienst (PID) betrieben. Fortbestand und Weiterentwicklung (u. a. Hybrid-System aus manuellen und automatischen Pollenfallen) dieses Messnetzes sind finanziell jedoch nicht gesichert. Im Sommer 2017 formierte sich daher der fachübergreifende Arbeitskreis "Bundesweites Pollenmonitoring", um sich über diesbezügliche Perspektiven für Deutschland auszutauschen. Für den Austausch kam der Arbeitskreis zwischen November 2017 und Juni 2018 zu 3 Gesprächstagen mit jeweils unterschiedlichen Themenschwerpunkten zusammen. Die internen Protokolle zu den Gesprächstagen bildeten anschließend die Grundlage für die Erstellung des vorliegenden Positionspapiers, mit dem der Arbeitskreis seine Arbeit abschließt. Aufgrund der Bedeutung allergener Pollen für die menschliche Gesundheit und allergischer Erkrankungen für das Gesundheitssystem spricht sich der Arbeitskreis dafür aus, das bundesweite Pollenmonitoring in den Katalog staatlicher Aufgaben aufzunehmen, die der grundlegenden Versorgung der Bevölkerung mit wesentlichen Gütern und Dienstleistungen dienen (öffentliche Daseinsvorsorge). Hinsichtlich möglicher Zuständigkeiten im Rahmen der öffentlichen Daseinsvorsorge wurden im Arbeitskreis mehrere Lösungsansätze diskutiert. Unabhängig von der zukünftigen Zuständigkeit kommt der Kooperation von messtechnischen, klinischen und wissenschaftlichen Einrichtungen eine grundsätzliche Bedeutung für die adäquate gesundheitliche Vorsorge zu. Dieses Positionspapier des fachübergreifenden Arbeitskreises "Bundesweites Pollenmonitoring" ist eine Übernahme aus dem Bundesgesundheitsblatt [Bundesgesundheitsblatt 2019;62:652-61, https:// doi.org/10.1007/s00103- 019-02940-y].

In the minimum battery of test inhalant allergens recommended by the Global Allergy and Asthma European Network 10 pollen allergens are included. Complementary other pollen allergens may need to be considered; however, respective awareness may not always be granted. Furthermore, at least in Germany, the situation may be even more complicated by the fact that test allergens need regulatory approval. A decline in commercially available test allergens may result in a diagnostic gap regarding patients with non-frequent allergies. How many patients with non-frequent pollen allergies would be affected by this gap? The data presented here partly answer this question. Methods The study consisted of a descriptive and an analytical part. In the descriptive part, sensitization to frequent pollen allergens (alder, hazel, birch, sweet grasses; according to the German Therapy Allergen Ordinance) and to respective non-frequent pollen allergens (cypress, Japanese cedar, ash, plane tree, olive, Bermuda grass, wall pellitory, plantain, goosefoot, mugwort, ragweed, and saltwort) was measured in adult patients with physician-diagnosed allergic rhinitis from two German federal states, namely North-Rhine Westphalia (n = 360) and Bavaria (n = 339), using skin prick testing and/or ISAC technology. Furthermore, respective regional pollen data were assessed. In the analytical part, sensitization data were correlated with each other and with anamnestic data on symptom periods. Results Sensitization to frequent pollen allergens ranged from 45% (sIgE to Aln g 1/Alder, NRW) to 72% (prick test reactivity to birch, NRW). Sensitization to non-frequent pollen allergens ranged from 0% (sIgE to Amb a 1/ragweed, NRW) to 41% (prick test reactivity to olive, Bavaria). Sensitization data partly correlated with each other and in connection with symptom periods showed a partly similar seasonal pattern as pollen data. Conclusions Sensitization to non-frequent pollen allergens have to be considered when examining patients with respective seasonal symptoms, and test (and respective therapy) allergens for non-frequent pollen allergies need to be available. Further prerequisites for adequate patient management would be a nationwide pollen monitoring system giving continuous pollen data and a systematic sensitization monitoring at patient level. © The Authors.Veröffentlichung Potential health risk of allergenic pollen with climate change associated spreading capacity(2016) Höflich, Conny; Kaiser, Lorraine; Mücke, Hans-Guido; Straff, WolfgangBackground: Global climate changes may influence the geographical spread of allergenic plants thuscausing new allergen challenges.
Objective: Allergy patients from two German federal states were compared for their status quo sensitization to ragweed, an establishing allergen, olive, a non-established allergen, and the native allergensbirch, mugwort, and ash.
Methods: Between 2011 and 2013, 476 adult allergy patients per region were recruited. Patients completed a questionnaire, participated in a medical interview, and underwent skin prick testing and bloodwithdrawal for analysis of specific IgE to allergen components (ISAC technology). Data on regional pollenload from 2006 to 2011 were acquired from the German Pollen Information Service Foundation.
Results: Prick test reactivity to ragweed and ash, respectively, was lower in Bavaria than in NRW (ragweed:p = 0.001, aOR = 0.54; ash: p = 0.001, aOR = 0.59), whereas prick test reactivity to olive was higher (p = 0.000,aOR = 3.09). Prick test reactivity to birch and mugwort, respectively, did not significantly differ. 1% (1/127)of patients with prick test reactivity to ragweed showed sIgE to Amb a 1, and 65% (86/132) of olive-but-not-ash reactive patients showed sIgE to Ole e 1 (NRW: 67%, Bavaria: 65%; p = 0.823, OR = 0.91). Regionaldifferences in sensitization pattern were neither explainable bycross-reactivity to pollen pan-allergensnor non-exposure variables nor by reported plant population or pollen data.
Conclusions: Spread of ragweed and particularly olive may result in prompt occurrence of allergic symptoms. Early identification of invasive allergens due to climate change does need time and spatial closemeshed measurement of respective indicator allergens and sensitization pattern.
