Background The prevalence of allergic disease to be increasing across the world. More than 20 of the population worldwide suffer from diseases which mediated by immunoglobulin E, such as asthma, rhinoconjunctivitis, atopic dermatitis or eczema. There is no data about allergen sensitization of allergic disease in Manado. Objective The purpose of this study is to know the allergen sensitization in children with allergic diseases atopic dermatitis, allergic rhinitis, asthma . Children were divided into group less than and more than or equal to 3 years old, which was evidenced by skin prick test or IgE Atopy test in Prof. Dr. R.D. Kandou Hospital Manado. Methods This study was a descriptive cross sectional study, conducted from June until August 2016. Results A total of 95 children were included in the study, of which 77 children were ge 3 years old and 18 children were 3 years old. Seventy five children underwent skin prick test and 20 children underwent IgEAtopy test. In 3 years old children, there were 14 children diagnosed with atopic dermatitis and 4 children diagnosed with atopic dermatitis and asthma. In ge 3 years old children, the most common diagnosis was allergic rhinitis, as many as 21 children. Allergen sensitization found in 3 years old children with atopic dermatitis and atopic dermatitis asthma was cow rsquo s milk, house dust mites and egg white. Sensitization to house dust mites most commonly found in patients with atopic dermatitis. The most common allergen sensitization in ge 3 years old children was house dust mites, egg white, potatoes, dog fur, cow 39 s milk, wheat flour and soya formula. Conclusion The most common allergen sensitization in 3 years old children with atopic dermatitis is cow 39 s milk, while in children with asthma and atopic dermatitis is house dust mites, whereas in ge 3 years old children with atopic dermatitis, allergic rhinitis, asthma, or combination of the disease is house dust mites.

Latar Belakang : Skin prick test SPT merupakan baku emas mendiagnosis sensitisasi alergen, namun memiliki keterbatasan. Pemeriksaan IgE spesifik merupakan pemeriksaan in vitro, nyaman dan tidak ada risiko anafilaksis.Tujuan: Mendapatkan akurasi pemeriksaan IgE spesifik serum metode ELISA dalam mendiagnosis sensitisasi alergen hirup pada pasien asma dan/atau rinitis alergi.Metode: Merupakan uji diagnostik dengan desain cross sectional pada pasien asma dan rinitis alergi di poliklinik Alergi-Imunologi FKUI-RSCM. Seratus pasien diperiksa IgE spesifik serum tungau debu rumah D.pterossinus, D.farinae, B.tropicalis , kulit anjing, kulit kucing dan kecoak dengan metode ELISA serta SPT sebagai baku emas mendiagnosis sensitisasi alergen tersebut. Sensitivitas, spesifisitas, nilai duga, dan rasio kemungkinan dari IgE spesifik serum dinilai untuk masing-masing alergen.Hasil: Sensitivitas IgE spesifik serum dalam mendiagnosis sensitisasi alergen tungau debu rumah berkisar 48-77 , dengan sensitivitas tertinggi 77 IK 95 66-86 pada D.farinae. Spesifisitas berkisar 64-95 , dengan spesifitas tertinggi 95 IK 95 76-99 pada B.tropicalis, serta nilai RK antara 2,1-11, dengan tertinggi untuk B.tropicalis. Sensitivitas mendiagnosis sensitisasi kecoak 12 IK 95 4,5-27 , namun spesifisitas 100 IK 95 92-100 , dengan RK . Spesifisitas mendiagnosis sensitisasi kulit anjing 89 IK 95 79-95 , namun senstitivitas 3 IK 95 1,5-17 , dengan RK hanya 0,29 IK 95 0,03-2,26 . IgE spesifik serum memiliki spesifitas 88 IK 95 77-95 dalam mendiagnosis sensitisasi kulit kucing, namun sensitivitas 10 IK 95 3,5-26 dan RK 0,9 IK 95 0,3-3,1 .Kesimpuan: Pemeriksaan IgE spesifik serum metode ELISA memiliki akurasi diagnostik yang sedang dalam mendiagnosis sensitisasi terhadap tungau debu rumah dan kecoak, namun akurasi rendah untuk kulit anjing dan kucingKata Kunci: Skin prick test IgE spesifik serum, Akurasi, Alergen hirup ......Background Skin prick test SPT is the gold standard to diagnose allergen sensitization, but has some limitations. Serum specific IgE SSIgE is in vitro test, comfortable and has no anaphylaxis risk.Aim To get the accuracy of SSIgE test using ELISA method in diagnosing inhalant allergens sensitization in asthma and or allergic rhinitis patients.Method This is diagnostic study with subjects were asthma and or allergic rhinitis patients. One hundreds patients had SSIgE test for house dust mites D.pterossinus, D.farinae, B.tropicalis , dog dander, cat dander and cockroach allergens and SPT as gold standard to diagnose allergen sensitization. Sensitivity, specificity, predictive value, and likelihood ratio of SSIgE were evaluated.Result To diagnose house dust mites sensitization SSIgE has 48 77 sensitivity, with the highest is for D.farinae 77 95 CI 66 86 , while specificity is 64 95 , with the highest is for B.tropicalis 95 95 CI 76 99 and LR around 2,1 11, with the highest is for B.tropicalis. Sensitivity of SSIgE to diagnose cockroach sensitization is 12 95 CI 4.5 27 , but has high specificity 100 95 CI 92 100 , and high LR . SSIgE has high specificity 89 95 CI 79 95 in diagnosing dog dander sensitization, but low sensitivity 3 95 CI 1.5 17 and low LR 0.29 95 CI 0.03 2.26 . To diagnose cat dander sensitization SSIgE has 88 95 CI 77 95 specificity, but low sensitivity 10 95 CI 3.5 26 and low LR 0.9 95 CI 0.3 3.1 Conclusion SSIgE test using ELISA method has moderate accuracy in diagnosing house dust mites and cockroach sensitization, but low accuracy for dog and cat dander sensitization.Keywords Skin prick test, Serum specific IgE, Accuracy, Inhalant Allergens

Background: nowadays, specific IgE measurement has been conducted in Indonesia, however there is still lack of data regarding diagnostic test to detect inhalant allergen in patients with respiratory allergies.This study aimed to determine the accuracy of specific IgE test in diagnosing specific sensitization of inhalant allergen in patients with respiratory allergies. Methods: this was a cross sectional study in patients with respiratory allergies and part of epidemiology study regarding to specific IgE sensitization in Allergy-Immunollogy Division, Cipto Mangunkusumo Hospital, Jakarta within November-December 2016. Measurement of specific IgE sensitization using Immunoblot method (Euroline, Euroimmun AG, Germany). The tested allergen is house dust mites Dermatophagoides pteronyssinus (Der p), Dermatophagoides farinae (Der f), Blomia tropicalis (Blo t) and cockroach Blatella germanica (Bla g). The result is compared with gold standard, skin prick test. The diagnostic result includes sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), positive likelihood ratio (LR+), and negative likelihood ratio (LR-). Results: a total of 101 patients were enrolled; 77 (76.2%) were women. Patients mean age was 38.8 years old. Based on SPT, sensitization was highest for Blo t (76.2%), followed by Der p (70.3%), Der f (69.3%), and Bla g (41.6%). Specific IgE-sensitization was highest for Der f (52.9%), followed by Der p (38.2%), Blo t (33.3%) and Bla g (10.8%). Der p allergen had 50.7% sentivity, 90% specificity, 92.3% PPV, 43.5% NPV, 5.1 LR+ and 0.1LR-. Der f showed 71.4% sensitivity, 87.1% specificity, 82.6% PPV, 57.4% NPV, 5.5 LR+ and 0.3 LR-. Blo t allergen had 41.6% sensitivity, 91.7% specificity, 94.1% PPV, 32.8% NPV, 5.0 LR+, and 0.6 LR-. Bla g allergen had 23.8% sensitivity, 98.3% specificity, 90.9% PPV, 64.4% NPV, 14.5 LR+ and 0.8 LR-. Conclusion: serum specific IgE testing to common inhalant allergen in patients with respiratory allergy showed only low-to-moderate sensitivity, but high specificity and PPV. This new assay can be used to diagnose allergen sensitization in the population with high prevalence of TDR and cockroach.
