"ABSTRAKInfeksi soil-transmitted helminths STH dengan prevalensi terbanyak Ascaris, diketahui dapat menstimulasi aktivasi Th-2 untuk menghasilkan sitokin yang dapat mengaktivasi IgE dan sel T regulator yang menekan inflamasi kronik tubuh. Hal ini diduga dapat mengurangi risiko terjadinya penyakit akibat inflamasi kronik, salah satunya diabetes melitus DM . Studi ini bertujuan untuk mengetahui hubungan antara infeksi STH yang ditandai dengan kehadiran antibodi IgE total dan spesifik dengan parameter metabolik berupa kadar glukosa darah puasa GDP dan setelah tes toleransi glukosa oral TTGO . Partisipan dari penelitian potong lintang cross section ini adalah penduduk berusia 15 tahun ke atas di 3 desa di Nangapanda daerah endemik infeksi STH yang berjumlah 298 partisipan. Kadar antibodi IgE merupakan hasil pengukuran ELISA sedangkan, kadar gula darah yang diukur menggunakan glukometer di darah kapiler merupakan data sekunder penelitian SUGARSPIN. Ditemukan hubungan negatif sangat lemah antara kadar IgE total dengan kadar TTGO rs=-0.197, p=0.001 . Sementara itu, tidak ditemukan hubungan antara kadar IgE total dengan kadar GDP, serta IgE spesifik dengan kadar GDP dan TTGO. Dari penelitian, dapat disimpulkan bahwa peningkatan kadar IgE total akan diikuti oleh penurunan kadar TTGO yang menggambarkan toleransi glukosa yang semakin baik.

ABSTRACTSoil transmitted helminths infection, whichthe most prevalent is Ascaris, is known with its capability to stimulate the activation of Th 2 to produce cytokines which can activate IgE and T reg resulting in suppression of chronic inflammation response. This may reduce the risk of diseases due to chronic inflammation, such as diabetes mellitus DM . Total and Specific Ascaris IgE level together with fasting blood glucose and oral glucose tolerance test level, are used as a study parameter. The aim of the study is to find out the relationship between STH infection, marked by total IgE and IgE specific level, and metabolic parameter, which is fasting blood glucose FBG and blood glucose after oral glucose tolerance test OGTT . Participants from this cross sectional study is population aged 15 years old and above, living in 3 villages in Nangapanda endemic for STH with total population 298. IgE level was the result of ELISA done in Leiden University while the blood glucose level, which is measured by glucometer from capillary blood, is a secondary data from SUGARSPIN study. Very weak negative association was found between total IgE level and OGTT level rs 0.197, dan p 0.001 meanwhile, no other association was found between dependent and independent variables. From this study, it can be concluded that the increased level of total IgE may lower OGTT level, which representate a better blood glucose tolerance. "

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."
