Nangapanda merupakan salah satu kecamatan di Flores, Indonesia yang memiliki prevalensi kecacingan usus sebesar 87,2 . Terdapat tiga jenis spesies cacing usus yang paling sering menyebabkan infeksi kecacingan, yaitu Ascaris lumbricoides, Trichuris trichiura, serta cacing tambang. Infeksi cacing usus akan menimbulkan respon imun tipe 2, sehingga menghasilkan respon imun humoral berupa pembentukan Immunoglobulin E IgE. Penelitian ini bertujuan untuk mengetahui hubungan antara status infeksi kecacingan usus dengan kadar IgE Total dan IgE spesifik terhadap Ascaris lumbricoides pada penduduk Nangapanda. Status infeksi kecacingan usus ditentukan dengan menggunakan metode Kato Katz, dimana dilakukan pencarian terhadap telur cacing pada sampel tinja pasien secara mikroskopis. Pada penelitian ini, dilakukan pengukuran antibodi IgE total dan spesifik terhadap Ascaris dalam sampel plasma dengan menggunakan metode ELISA. Didapatkan peningkatan kadar antibodi IgE Total yang bermakna pada kelompok terinfeksi oleh setidaknya satu jenis cacing usus P ......Nangapanda is one of the endemic areas in Indonesia with a very high STH prevalence 87,2 . Ascaris lumbricoides, Trichuris trichiura, and hookworms are the most prevalent etiologies of helminth infection. When helminth infects the body, it will enhance the type 2 immune response which will lead to the production of humoral immunity such as Immunoglobulin E. This research aimed to identify the relationship between STH infection status with the Total IgE and Ascaris specific IgE levels. The STH infection status was determined by Kato Katz method to identify the presence of STH rsquo s eggs in the stool sample microscopically. In this research, the levels of total and specific IgE in the plasma samples were detected by ELISA. The levels of Total IgE was increased significantly in helminth infected group.

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.

House dust mites (HDM) are an important inhalant allergen in allergic asthma. However, molecular diagnostic study of specific IgE to HDM allergens has not been done in Indonesia. in addition, the association of quantitative specific IgE measurement with asthma severity has not been investigated. This study aimed to investigate difference of serum quantitative specific IgE levels induced by Dermatophagoides (D).

Latar belakang: Tungau debu rumah TDR merupakan alergen hirup yang penting pada asma alergik. Namun, penelitian diagnostik molekuler menggunakan Imunoglobulin E IgE spesifik akibat sensitisasi alergen TDR dihubungkan dengan derajat keparahan asma alergik belum pernah dilakukan di Indonesia. Tujuan: Mengetahui perbedaan kadar IgE spesifik serum kuantitatif akibat sensitisasi alergen Dermatophagoides D. pteronyssinus, D. farinae dan Blomia B. tropicalis pada asma alergik intermiten dan persisten. Metode: Desain penelitian potong lintang pada pasien asma alergik dewasa yang diundang untuk pemeriksaan IgE spesifik serum dan merupakan bagian dari penelitian payung di Divisi Alergi dan Imunologi Klinik, RS Cipto Mangunkusumo. Derajat keparahan asma ditentukan berdasarkan kriteria Global Initiative on Asthma GINA 2015 dan dikelompokkan menjadi intermiten dan persisten. Pemeriksaan IgE spesifik serum kuantitatif menggunakan metode multiple allergosorbent test Polycheck Allergy, Biocheck GmbH, Munster, Germany . Alergen TDR yang diperiksa adalah D. pteronyssinus, D. farinae, dan B. tropicalis. Perbedaan antara dua kelompok dianalisis dengan uji Mann-Whitney. Hasil: Sebanyak 87 subyek dilibatkan dalam penelitian ini; 69 79,3 subyek adalah perempuan. Rerata usia pasien adalah 40,2 tahun. Enam puluh tiga 72,4 pasien menderita asma dan rinitis alergik. Sebanyak 58 66,7 pasien asma persisten. Gambaran sensitisasi alergen TDR adalah 62,1 D. farinae; 51,7 D. pteronyssinus dan 48,3 B.tropicalis. Median kadar IgE spesifik secara bermakna lebih tinggi pada asma persisten dibandingkan asma intermiten untuk alergen D. farinae 1,30 vs. 0,0 kU/L; p=0,024 dan B. tropicalis 0,57 vs. 0,0 kU/L; p=0,015 . Kadar IgE spesifik D. pteronyssinus lebih tinggi pada asma persisten dibandingkan intermiten 0,67 vs. 0,00 kU/L; p=0,066. Kesimpulan:Gambaran sensitisasi alergen secara berurutan didapatkan D. farinae 62,1, D. pteronyssinus 51,7 dan B. tropicalis 48,3 .

Introduction House dust mites HDM are an important inhalant allergen in allergic asthma. However, molecular diagnostic study using specific IgE level induced by HDM allergens associated with asthma severity has not been done in Indonesia. Objective To investigate the difference of serum quantitative specific IgE levels induced by Dermatophagoides D. pteronyssinus, D. farinae and Blomia B. tropicalis sensitization in intermittent and persistent allergic asthma. Method This was a cross sectional study on adult allergic asthma patients who were invited for serum specific IgE testing. This study was a part of a larger research within the Division of Allergy and Immunology, Cipto Mangunkusumo Hospital. Asthma severity was defined based on Global Initiative on Asthma GINA 2015 criteria and were grouped as intermittent or persistent. Quantitative specific IgE testing was done on blood serum using a multiple allergosorbent test Polycheck Allergy, Biocheck GmbH, Munster, Germany . The HDM allergens tested were D. pteronyssinus, D. farinae, and Blomia tropicalis. Difference between two groups were analyze using Mann Whitney test. Results A total of 87 subjects were enrolled in this study 69 79.3 were women. Mean patients rsquo age was 40, 2 years. Sixty three 72.4 patients had asthma and allergic rhinitis. Fifty eight 66.7 patients were classified as persistent asthma. The prevalence of sensitization was 62.1 D. farinae, 51.7 D. pteronyssinus, and 48.3 Blomia tropicalis. The median of specific IgE levels is significantly higher in persistent asthma compares to intermittent asthma induced by D. farinae median 1.30 vs. 0.0 kU L p 0.024 and B. tropicalis median 0.57 vs. 0.0 kU L p 0.015 sensitization. Level of Specific IgE D. pteronyssinus is also to be higher in persistent asthma than the level measured in intermittent asthma 0.67 vs. 0.00 kU L p 0.066. Conclusion Sensitization of HDM allergens is shown to be highest for D. farinae 62.1 , followed by D. pteronyssinus 51, 7 and Blomia tropicalis 48, 3 . Specific IgE level induced by D. farinae and Blomia tropicalis sensitization are significantly higher in patients with persistent compares to intermittent asthma, whereas specific IgE level induced by D. pteronyssinus sensitization to be higher in persistent asthma although not statistically significant.
