    Allergies in a Changing Environment in Europe
    21 March 2012, Brussels, EU-Parliament

    The EAACI Interest Group „Aerobiology and Air Pollution” organised a 2 hours workshop in the EU-Parliament in Brussels. The aim was to make politicians aware of the ongoing epidemic in allergic disease (Prof. Dr. Isabella Annesi-Maesano, France, and Peter Burney, UK), that current therapies are still insufficient (Prof. Dr. Antonella Muraro, Italy), that changed land use in the EU can lead to more allergic sensitizations (Prof. Dr. Carmen Galan, Spain), and that allergies are an environmental, multifactorial disease that need a concerted research approach (Prof. Dr. Jeroen Buters, Germany). We tried to identify where the EU currently spends it research money on allergic diseases (Prof. Buters), and where more attention is needed (exposome). A 30 minutes panel discussion led by Dr. Lorenzo Cecchi (Italy) and supplemented with Prof. Mikhail Sofiev (Finland) gave stakeholders time to vent their interests.

    The key messages were:
    1. Currently an epidemic in allergic disease going on and an end is not in sight
    2. More research funding into the causes of this increase is needed

    A Member of Parliament, Esther de Lange, sponsored and spoke at our meeting. About 46 participants were present, including WHO, FP7 and patient organisation stakeholders. Surprisingly was the vivid interest of patient organisations (Allergy UK, European Federation of Allergy, EFA, European Public Health Alliance, EPHA, and more). They would like to be heard by politicians and concluded that allergic patients are not satisfied with the current situation and ask for improvements (more funding for pollen monitoring and into the causes of the epidemic).

    Although we had hoped for more Members of Parliament and the Commissions, the workshop was a success. In the Parliament many parallel sessions are held, like on “The Effect of Climate Change on Illegal Immigration”, “Healthy Buildings”, “COPD” (all at the same time), and on this political market “Allergies” is just another stand. We need to do more to be heard. This EAACI workshop was the beginning of a series of workshops planned by the Academy.

    I thank all the participants for devoting time to this political activity.

    Interest Group Aerobiology and Air Pollution Secretary

  • Minutes TF Allergen Monitoring

  • EAACI Public Workshop

    Allergies are the most prevalent chronic diseases in Europe with a >20% frequency. Allergic diseases to airborne allergens have been steadily increasing over the past few decades and an end of this increase is not in sight. Especially the younger generations show a higher incidence of allergic diseases. Thus, by the year 2040, more than 40% of the population will present an allergic predisposition in Europe.

    The reasons for this steady increase are unclear. The Interest Group Aerobiology and Air Pollution of the EAACI (European Academy of Allergy and Clinical Immunology) is organizing a workshop to inform stakeholders about the ongoing and future developments in allergy research in Europe to
    increase the public awareness for this ongoing epidemic.

    Epidemiological evidence on the links between aerotoxicants and allergic diseases

    Berlin, October 13, 2011
    Charité Hospital

    Submitted by Dr Lorenzo Cecchi, Dr Isabella Annesi-Maesano and Prof Karl-Christian Bergmann


    Exposures to bioaerosols and chemical pollutants are associated with a wide range of allergic and health effects with major public health impact, including acute toxic effects, allergies, infectious diseases, and cancer. Respiratory symptoms and diseases and lung function impairment are the most widely studied and probably among the most important aerotoxicant-associated health effects. In addition to these adverse health effects, some protective effects of microbial exposure on atopy and atopic conditions have also been suggested. A dose–response relationship has not been established for most agents and knowledge about threshold values is sparse.

    The purpose of the workshop is to collect major experts in the field of allergic diseases to present the state of art on the links between aerotoxicants and allergic diseases and identify unmet needs. Specific recommendations will be implemented.

    The workshop will be held at the occasion of the COST Action meeting in Berlin, October 14-15, 2011.

  • Task force

    Effects of Climate change on respiratory allergic diseases and on asthma prevalence

    Task force on “Effects of Climate change on respiratory allergic diseases and on asthma prevalence”


    It is now widely accepted that earth’s temperature is increasing and changes are also occurring in the amount, intensity, frequency and type of precipitation and in occurrence of extreme events.

    As stated in the 2007 Working Group I Report of the Intergovernmental Panel on Climate Change “most of the observed increase in globally averaged temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations”.

    The effects of climate change on respiratory allergy are still unclear and current knowledge is provided by epidemiological and experimental studies on the relationship between asthma and environmental factors, like meteorological variables, airborne allergens and air pollution. The socio-economic burden of allergic diseases and their increasing prevalence, especially in developing countries, make a systematic analysis of possible effects of current climate change scenarios on asthma and atopy an hot topic for both EAACI and ERS.

    Current knowledge about environmental factors affecting allergic airways diseases is still fragmentary and relationships between factors partly unclear. The need of a multidisciplinary approach might be one of the reasons why a comprehensive analysis of this issue is still lacking.

    In our opinion, the document produced by the Task Force, might represent the first (mandatory) step to identify the interventions able to mitigate possible effects of climate change on asthmatic and atopic patients. The Position Paper might provide the scientific background for political interventions on both national and European levels.


    The aim of the Task Force is to provide, through a multidisciplinary approach, a document containing: - a state of the art of environmental factors (and their inter-relationships) affecting asthma and atopic diseases - a comprehensive evaluation of the influence of weather variables on environmental factors and possible effects of current climate change scenarios - the possible effects of climate change on the prevalence of asthma and atopic diseases, on the basis of current hypotheses (“Hygiene Hypothesis”) and studies (effects of air pollution on lung development, etc) - the interventions able to mitigate negative effects.

    Intergovernmental panel on climate change (IPCC):
    The Intergovernmental Panel on Climate Change (IPCC) is the leading international body for the assessment of climate change. It was established by the United Nations Environment Programme (UNEP) and the World Meteorological Organization (WMO) to provide the world with a clear scientific view on the current state of knowledge in climate change and its potential environmental and socio-economic impacts.

    The IPCC is a scientific body. It reviews and assesses the most recent scientific, technical and socio-economic information produced worldwide relevant to the understanding of climate change. It does not conduct any research nor does it monitor climate related data or parameters.

    Thousands of scientists from all over the world contribute to the work of the IPCC on a voluntary basis. Review is an essential part of the IPCC process, to ensure an objective and complete assessment of current information. IPCC aims to reflect a range of views and expertise. The Secretariat coordinates all the IPCC work and liaises with Governments.

    The IPCC is an intergovernmental body. It is open to all member Countries of the United Nations (UN) and WMO. Governments can participate in the review process and plenary Sessions, where main decisions about the IPCC work programme are taken and reports are accepted, adopted and approved. The IPCC Bureau Members including the Chair are also elected during the plenary Sessions.

    Because of its scientific and intergovernmental nature, the IPCC embodies a unique opportunity to provide rigorous and balanced scientific information to decision makers. By endorsing the IPCC reports, governments acknowledge the authority of their scientific content. The work of the organization is therefore policy-relevant and yet policy-neutral, never policy-prescriptive.
