Abstract

Aim: Knowledge about the role of the innate immune system in thepathogenesis of allergic diseases has been expanding in recent years.Defensins are antimicrobial peptides that are components of the innateimmune system. Defensins have strong efficacy against bacterial,viral, and fungal infections. Moreover, they have regulatory functions inmany physiologic processes such as antitumoral immunity, chemotaxis,inflammation, and wound healing. In this study, we aimed to investigateβ-defensin 2 levels in the nasal fluids of children with allergic rhinitis.Material and Methods: Study and control groups consisted of 28 patientswith newly diagnosed allergic rhinitis who were not taking anymedication, and 23 healthy children. Skin prick tests were performedon patients with allergic rhinitis and disease severity was assessed usingthe total symptom score. Nasal fluid samples were obtained usinga modified polyurethane sponge absorption method from patientsand control subjects. Nasal fluid β-defensin 2 levels were determinedusing an enzyme-linked immunosorbent assay (ELISA).Results: The median value of nasal fluid β-defensin 2 levels were173.8 pg/mL (interquartile range; 54.8-205.9 pg/mL) in allergic rhinitisgroup and 241.6 pg/mL (163.5-315.2 pg/mL) in the control group.There was a statistically significant difference between the two groups(p=0.01). Moreover, nasal fluid β-defensin 2 levels showed a significantnegative correlation with total symptom scores (rho= -0.78, p

Özet

Amaç: Son yıllarda doğal immün sistemin alerjik hastalıkların patogenezindeki rolü konusunda bilgi birikimi artmaktadır. Antimikrobiyal peptidlerden olan defensinler doğal immün sistemin önemli bileşenlerindendir. Defensinler bakteri, virüs ve mantar enfeksiyonlarına kar- şı güçlü etkinlik gösterirler. Ayrıca; antitümoral immünite, kemotaksi, enflamasyon ve yara iyileşmesi gibi birçok fizyolojik süreçte düzenleyici işlevleri vardır. Bu çalışmamızda alerjik rinitli çocukların nazal sıvılarındaki ?-defensin 2 düzeylerini araştırmayı amaçladık. Gereç ve Yöntemler: Çalışma ve kontrol grupları; 28 yeni tanı konulmuş, hiç tedavi almamış alerjik rinit tanılı hasta ve 23 sağlıklı çocuktan oluşturuldu. Alerjik rinit tanılı hastalara alerjenlerle deri testleri yapıldı ve hastalığın şiddeti toplam belirti puanı kullanılarak değerlendirildi. Hasta ve kontrol grubunun nazal sıvıları değiştirilmiş bir poliüretan sünger absorbsiyon yöntemi ile toplandı ve ?-defensin 2 düzeyleri ELISA yöntemi ile ölçüldü. Bulgular: Alerjik rinit tanılı hastaların nazal sıvı ?-defensin 2 düzeylerinin ortanca değeri 173,8 pg/mL (çeyrekler aralığı; 54,8-205,9) iken kontrol grubunun ortanca ?-defensin 2 değeri 241,6 pg/mL (163,5- 315,2) idi. Gruplar arasında istatistiksel olarak anlamlı farklılık vardı (p=0,01). Ayrıca, nazal sıvı ?-defensin 2 düzeyleri ve toplam belirti puanı arasında anlamlı bir negatif korelasyon izlendi (rho:-0,78, p
