Abstract

Epidemiological studies suggest a relationship between particulate air pollution and prevalence of allergic airway diseases such as allergic rhinitis, whose prevalance is getting increased in recent years. Diesel exhaust particles (DEP), which constitute the main fraction of particulate air pollution, have become a serious problem in Turkey, and worldwide as a result of increased use of diesel motor vehicles due to the low cost and high efficiency. DEP are composed of nanoscaled particles (< 0.1 &#956;m) and larger particles. DEP act as carriers for the transport of allergens into the airways by binding allergenic proteins onto their surfaces. Studies investigating the mechanisms underlying effects of DEP on upper airways have demonstrated that DEP lead to increases in both the synthesis of total and specific IgE, and the response to the allergen-induced eosinophilic inflammation, and allergen presentation.

Özet

Epidemiyolojik çalışmalar, son yıllarda prevalansları giderek artan allerjik rinit gibi allerjik hava yolu hastalıkları ile partiküler hava kirliliği arasında bir ilişki olduğunu düşündürmektedir. Partiküler hava kirliliğinin önemli bir fraksiyonunu oluşturan dizel egzoz partikülleri (DEP), maliyetinin düşük olması ve veriminin yüksek olması nedeniyle dizel kullanan motorlu araç sayısındaki artış sonucunda dünyada ve Türkiye’de ciddi bir sorun halini almıştır. DEP, nano ölçekli partiküller (< 0.1 μm) ile daha büyük çaplı partiküllerden oluşmaktadır. DEP’in allerjenik proteinlerin yüzeyine bağlanmasını sağlayarak allerjenlerin hava yollarına ulaşmasında taşıyıcı rol oynadığı ileri sürülmektedir. DEP’in üst hava yolları üzerine olan etkilerinin altında yatan mekanizmaları araştıran çalışmalar, bu partiküllerin total ve spesifik IgE sentezini, allerjene bağlı eozinofilik inflamasyon yanıtını ve allerjen sunumunu artırdığını göstermektedir.
