Endotelina-1 w popłuczynach nosowych chorych na alergiczny nieżyt nosa – potencjalny mediator reakcji alergicznej ☆ ☆☆
2007
Summary The nasal epithelium is considered to play an active role in the allergic inflammation through its capacity to synthesize and release a wide range of cytokines and mediators. Few studies have investigated the involvement of endothelin-1 in the pathogenesis of inflammatory diseases of the upper airways. To examine the release of endothelin-1 from nasal mucosa after allergen challenge we investigated 24 patients. 15 subjects (7 male, 8 female) allergic to birch pollen aged 37,1 ± 4,9 years participated in the study. Nasal birch allergen provocation with following lavage was performed in all subjects. Endothelin-1 in the nasal secretion were assayed before and after challenge. Increase in concentration of endothelin-1 in nasal lavage fluid from allergic patients were significantly higher than in control group respectively from 18,33 ± 5,47 fmol/ml to 26,41 ± 6,92 fmol/ml versus 18,8 ± 3,99 to 19,80 ± 4,18 fmol/ml (p
