Objective & Hypothesis:Objective: In this study, CD23, low affinity immunoglobu-lin E receptor, expression in the adenoid tissue was inves-tigated immunohistochemically and evaluated with regardto upper respiratory tract infection complaints and allergy.Methods: This retrospective study was performed by theselection of 100 patients aged 2-13 years who underwentadenoidectomy/adenotonsillectomy and in whom the ad-enoid tissue pathological studies were reported as “lym- phoid hyperplasia and chronic infection” were evaluated.Immunohistochemical evaluation of CD23 expressionwas scored semiquantitatively between 0-3 in the tissuesamples.Results: The mean age in the study group was 70.7 months; 46% were female; 30% of patients had adenoid- ectomy only.

Abstract

Objective: In this study, CD23, low affinity immunoglobu-lin E receptor, expression in the adenoid tissue was inves-tigated immunohistochemically and evaluated with regardto upper respiratory tract infection complaints and allergy.Methods: This retrospective study was performed by theselection of 100 patients aged 2-13 years who underwentadenoidectomy/adenotonsillectomy and in whom the ad-enoid tissue pathological studies were reported as “lym- phoid hyperplasia and chronic infection” were evaluated.Immunohistochemical evaluation of CD23 expressionwas scored semiquantitatively between 0-3 in the tissuesamples.Results: The mean age in the study group was 70.7 months; 46% were female; 30% of patients had adenoid- ectomy only. Following the operation, the infection fre- quency decreased in 91% of patients, whereas allergy symptoms were unchanged in 84%. CD23 expression was found significantly lower in patients who had allergic manifestations, namely urticaria (p=0.041), drug sensitiv- ity (p=0.035) and pollen allergy (p=0.037). Conclusion: A significantly reduced CD23 expression was found in adenoidal tissue in patients with allergic symptoms. These results can be assessed as an under- lying mechanism for the recurrence of respiratory tract complaints in these children, despite adenoidectomy. J Clin Exp Invest 2013; 4 (1): 1-7

Özet

Amaç: Bu çalışmada, CD23, IgE’nin düşük afiniteli reseptörü immunohistokimyasal yöntemle değerlendirildi ve üst solunum yolu enfeksiyonu ve alerji semptomlarının varlığına göre analiz edildi. Yöntemler: Bu retrospektif çalışmaya yaşları 2-13 yaşarasında değişen adenoidekromi ve adenoidektomi/ tonsillektomi operasyonu geçiren 100 hasta alındı. Patolojiraporları lenfoid hiperplazi ve kronik enfeksiyon şeklinde olanlar çalışmaya dahil edildi. Immunohistokimyasal olarak CD23 ekspresyonu semikantitatif metodla (0-3) arasında değerlendirildi. Bulgular: Çalışma grubunun ortalama yaşı 70,7 ay, % 46’sı kız hastalardan oluşmaktaydı ve hastaların % 30’u sadece adenoidektomi operasyonu geçirmişti. Operas- yon sonrası, enfeksiyon sıklığı % 91 oranında azalmakla birlikte, alerji semptomları %84 oranında değişmemişti. CD23 ekspresyonu özellikle ürtiker yakınması olanlarda (p=0,037), ilaç alerjisi olanlarda (p= 0.035) ve polen alerjisi (p= 0.041) olanlarda anlamlı olarak düşük bulundu. Sonuç: Atopik hastalarda adenoid dokuda CD23 yüzey ekspresyonunun azalacağı tezini destekler şekilde ürtiker, ilaç allerjisi ve polen allerjisi olan hastalarda CD23 yoğunluğunu anlamlı olarak azalmış saptandı. Bu sonuçlar, adenoidektomiye rağmen tekrarlayan solunum yolu semptomları olan çocuklarda altta yatan mekanizmayı açıklamak açısından değerlendirilebilir.
