Abstract

Objective: Skin prick testing with commercial allergens is the most commonly used method for detection of food specific IgE. However, standardized commercial products are not available for most of the allergens and it has been shown that some patients with a history of food allergy having negative skin prick test results with commercial allergens, have positive results with the raw extracts of the same foods. In this study, we aimed to compare the results of skin prick tests performed with commercial and raw cow&#8217;s milk and egg white extracts and evaluate their correlation with serum specific immunoglobulin E levels. Materials and Methods: We conducted a retrospective analysis of patients having symptoms of allergic diseases who were performed skin prick tests with raw and commercial extracts of cow&#8217;s milk and egg white at pediatric allergy department. Presenting symptoms, family history and laboratory findings were obtained from regular medical records. Results: A total of 130 patients with a mean age of 12.1 ± 17.3 were enrolled in the study and 66.7% (88) of them were male. Within the skin prick tests with cow&#8217;s milk and/or egg white, 90.4% of them were positive with raw extracts and 72.1% were positive with commercial extracts. Egg white specific IgE levels were positive in 77.8% of patients having positive skin prick test only with raw egg white, while it was positive in 10.0% of patients having positive skin prick test only with commercial egg white allergen (p= 0.001). A total of 21 patients had positivite skin prick tests only with raw cow&#8217;s milk and 20 of them have also positive cow&#8217;s milk specific IgE levels. Egg white specific IgE levels were positive in 78.2% of patients having greater enduration with raw egg white, while it was positive in 8.3% of patients having greater enduration with commercial egg white allergen (p< 0.001). The mean cow&#8217;s milk specific IgE level was 7.0 ± 9.8 in patients having greater enduration with raw cow&#8217;s milk and there was one patient who had higher enduration with raw cow&#8217;s milk and his specific IgE level was 0.41. Conclusion: The positivity rate and mean diameter of enduration with raw food extracts was higher than commercial extracts. And also correlation with serum specific IgE levels and raw food extracts was more significant than the correlation with commercial extracts.

Özet

Giriş: Besin allerjenlerine karşı IgE antikorunu belirlemede en sık kullanılan yöntem ticari allerjenlerle deri prik testini yapmaktır. Birçok allerjenin ticari standardize ekstresi bulunmaktadır. Ancak yapılmış çalışmalarda besinlerle şikayeti olan bazı hastaların ticari allerjen ekstreleriyle yapılan deri prik testlerinde duyarlılık görülmezken aynı besinlerin doğal çiğ ekstreleri ile reaksiyon geliştiği görülmüştür. Bu çalışmada inek sütü ve yumurta akı ile yapılan allerjen deri prik testinde çiğ ve ticari ekstrelerinin reaksiyonları karşılaştırılıp bunun serum spesifik IgE ile korelasyonu araştırılmıştır. Gereç ve Yöntem: Hastanemizin allerji polikliniklerine allerjik hastalık semptom öyküsüyle başvuran ve yumurta akı ve/veya inek sütünün ticari ve çiğ ekstreleri ile allerjen deri prik testi yapılmış olan hastaların dosyaları retrospektif olarak incelendi. Hastaların başvuru şikayetleri, öz geçmişleri, soy geçmişleri ve laboratuvar bulguları dosyalarından incelendi. Bulgular: Çalışmaya yaş ortalaması 12.1 ± 17.3 ay olan ve %67.7 (88 hasta)’si erkek olan toplam 130 hasta alındı. Yumurta veya inek sütü ile deri prik testlerinin %90.4’ünde çiğ formlar ile test pozitifken, %72.1’inde ticari formlar ile deri testi yanıtları pozitif bulundu. Sadece çiğ yumurta akı allerjen deri prik testi pozitif olanların %77.8’inde yumurta akı spesifik IgE pozitif iken, sadece ticari yumurta akı allerjen deri prik testi pozitif olanların %10’unda yumurta akı spesifik IgE pozitifti (p= 0.001). Sadece çiğ inek sütü allerjen deri prik testi pozitif olan 21 hastanın 20’sinde inek sütü spesifik IgE pozitifti. Sadece ticari inek sütü allerjen deri prik testi pozitif olan 1 hasta olup onun da inek sütü spesifik IgE’si pozitifti. Allerjen deri prik testinde çiğ yumurta akı endürasyonu büyük olanların %78.2’sinde yumurta akı spesifik IgE pozitifken, ticari yumurta akı endürasyonu büyük olanların %8.3’ünde yumurta akı spesifik IgE pozitifti (p< 0.001). Çiğ inek sütü endürasyonu büyük olan hastaların inek sütü spesifik IgE ortalaması 7.0 ± 9.8 iken, ticari inek sütü endürasyonu büyük olan sadece bir hasta vardı ve onun inek sütü spesifik IgE’si 0.41 idi. Sonuç: Ticari besin ekstrelerine göre çiğ besin ekstreleriyle yapılan allerjen deri prik testleri hem daha fazla pozitif hem de endürasyon çapları daha büyüktür. Ayrıca ticari besin ekstreleriyle karşılaştırıldığında çiğ besin ekstreleriyle yapılan allerjen prik deri testlerinin spesifik IgE ile korelasyonu daha fazladır.
