Abstract

Objectives: We investigated the role of specific IgE assay in the diagnosis in patients found to be atopic or allergic by history and physical examination. Patients and Methods: Serum specific IgE levels were measured by the chemiluminescent assay in 143 adults (58 females, 85 males; mean age 34.3 years; range 16 to 62 years) and in 113 children (62 girls, 51 boys; mean age 10.2 years; range 5 to 16 years) with rhinitis, asthma, or dermatitis. The results were analyzed in six groups depending on the specific IgE level (no specific IgE, very low, low, moderate, high, and very high levels). The specific IgE threshold for a negative or positive result was accepted as 0.70 IU/ml. Allergen-specific IgE anti-bodies were sought for 35 allergens in adults, and for 19 allergens in children. Results: Specific IgE levels were positive (>0.70 IU/ml) in 92 adults (64.34%) and in 50 children (44.25%). Hypersensitivity to individual allergens ranged between 20.08% and 41.96% in adults, and between 17.70% and 28.32% in children. Fourteen adults and eight children showed sensitivity to a single allergen; the remaining patients were sensitive to at least two allergens. Conclusion: Detection of sensitivity to allergens is complementary to findings obtained by history and physical examination and may help to reveal allergic etiology in patients presenting with a similar symptom profile.

Özet

Amaç: Öykü ve fizik muayene ile alerjik veya atopik olarak değerlendirilen olgularda spesifik IgE bakısının tanıdaki yeri değerlendirildi. Hastalar ve Yöntemler: Rinit, astım veya dermatitli 143 erişkin (58 kadın, 85 erkek; ort. yaş 34.3; dağılım 16-62) ve 113 çocukta (62 kız, 51 erkek; ort. yaş 10.2; dağılım 5-16) serum spesifik IgE düzeyleri ölçüldü. Ölçümler kemilüminesans tekniği ile yapıldı; elde edilen sonuçlar altı grupta değerlendirildi (spesifik IgE saptanmayan ya da çok düşük düzeyde saptanan olgular, düşük, orta, yüksek ve çok yüksek düzeyler). Spesifik IgE düzeyinin 0.70 lU/ml) pozitif sonuç şeklinde yorumlandı. Erişkinlerde 35 ayrı alerjen için, çocuklarda ise 19 ayrı alerjen için spesifik IgE düzeylerine bakıldı. Bulgular: Erişkinlerin %64.34'ünde (92 olgu), çocukların %44.25'inde (50 olgu) pozitif spesifik IgE düzeyi (>0.70 IU/ml) saptandı. Tek tek alerjenlere karşı duyarlılık erişkinlerde %20.08 ile %41.96; çocuklarda %17.70 ile %28.32 arasında değişmekteydi. Sadece tek bir alerjene duyarlılık erişkinlerde 14 olguda, çocuklarda sekiz olguda görüldü; diğer olgularda en az iki alerjene karşı duyarlılık saptandı. Sonuç: Benzer semptomlara sahip hastalıklarda alerjik etyolojinin ortaya konmasında alerjenlere duyarlılığı ölçen serumda spesifik IgE bakısı gibi testler, öykü ve fizik muayene bulgularını destekleyici niteliktedir.
