Beberapa kasus urtikaria pada paparan debu dan diantaranya menghubungkan sensitivitas tungau debu rumah (TDR) dengan urtikaria berdasarkan riwayat pasien dan pemeriksaan uji intradermal. Tujuan penelitian ini adalah menentukan korelasi antara kepadatan TDR dan rekurensi urtikaria. Jumlah sampel pada penelitian ini 30 orang. Kepadatan TDR dari tiap kamar sampel dihitung dengan mengumpulkan debu, dan sampel dinilai sensitivitas terhadao TDR dengan pemeriksaan skin prick test (SPT). Diagnosis urtikaria berdasarkan anamnesis, kemudian ditanyaan rekurensinya dalam tiga bulan terakhir. Hasil: Dari 30 peserta, tujuh (23,3%) sampel memiliki kepadatan TDR sedang sementara 23 (76,7%) memiliki kepadatan rendah. Selain itu, 15 sampel positif SPT terhadap alergen TDR. Dari anamnesis, 12 (40%) sampel didiagnosis urtikaria dan diantaranya, 11 orang (91,67%) positif terhadap SPT. Tidak ada sampel yang memiliki rekurensi urtikaria dalam tiga bulan terakhir. Kesimpulan: Meskipun penelitian ini tidak menunjukkan korelasi yang signifikan antara kepadatan TDR dan tingkat kekambuhan urtikaria (p> 0,05), TDR memang bisa memicu eksaserbasi. Penelitian ini membutuhkan penyelidikan lebih lanjut dengan ukuran sampel yang lebih besar.

<p class="abstract"><strong>Background:</strong> The urticaria lasting for more than 6 weeks is termed chronic urticaria. The etiology of chronic urticaria and angioedema remains uncertain in most of the patients. Aeroallergens can induce or exacerbates chronic urticaria. The common aeroallergens are house dust mites (HDM), pollens, moulds, etc. House dust mites can trigger immunological process through ingestion, inhalation or inoculation. These mite allergens are resistant to high temperatures, and do not lose their antigenic property even on cooking. HDMs can also cause worsening of existing atopic dermatitis.

Background: House dust mites are inhaled allergens and as a trigger of the onset of allergic diseases such as bronchial asthma, atopic dermatitis, conjunctivitis, and alergic rhinitis. Mites are the major allergenic components from house dust. House dust mite section containing allergens in the cuticle, the sex organs and the gastrointestinal tract. Approximately 80% of patients allergic to house dust mites have specific IgE antibodies against group I and II allergens that clinically associated with asthma, atopic dermatitis, alergic rhinitis. This IgE can be detected in serum by immune assay or on the skin with a skin allergy test.Purpose: To provide a profil picture of allergy with the result of skin prick test positive to housedust mites in allergy - immunology clinic medicine in public hospital Prof. Kandou period 2007 - 2009.Method and results : This study uses a retrospective descriptive method trough medical records at the allergy- immunology clinic in public hospital Prof. Kandou period 2007 - 2009. Result of this study, the number of allergy sufferers with positive results of skin prick test of house dust mite is 136 patients, with the highest prevalence in 2008. Earned women more than men, highest in the age group 51 - 60 years, most patients work as civil servants, and most diagnosis was found is bronchial asthma.Keyword : house dust mite, allergy, skin prick test.ABSTRAKLatar Belakang: Tungau Debu Rumah (TDR) merupakan alergen hirup dan sebagai faktor pencetus timbulnya penyakit alergi seperti asma bronkial, dermatitis atopik, konjungtivitis, dan rinitis alergik.1-4 Tungau merupakan komponen alergenik utama dari debu rumah.

Abstract: House Dust Mites (HDM) is one of the allergen that triggers allergic reactions, such as asthma, atopic dermatitis, allergic rhinitis, and conjunctivitis, also it could happen to anyone. One of the common ways to do an allergic test, is Skin Prick Test, and this kind of test often performed in hospital. The aim of this study is to know the profile of patients with positive result in Skin Prick Test of HDM. This is a descriptive retrospective study. Subject of this study is medical records of all the patients that diagnosed as allergy with positive results in Skin Prick Test of HDM in Allergy-Immunology department of Prof. Kandou hospital Manado from January 2010 – October 2012. The data is then  processed in the form of tables/graphs that are included based on frequency of year of occurrence, sex, age, occupation, and diagnose. It is included that the number of patients who met the study criteria are 119 patients, with the highest peak in the year 2010 (39.5%), women patients are more than males (53.8%), the largest age group is 51-60 years (29, 4%), most jobs are civil servants (26.0%), and bronchial asthma (28.6%) is the highest diagnosis.

Abstract This study was conducted to determine the influence of environmental factors on the prevalence of house dust mites in student dormitories of Bandar Abbas city. In this study, 64 dust samples were collected from seven randomly selected dormitories located in various areas of the Bandar Abbas. The collected mites were isolated and mounted in Hoyer’s medium and identified using a morphological key. The associations between the environmental factors and the density of house dust mites were investigated. In total, 1,093 adult mites were collected and identified. They consisted of four species including Dermatophagoides pteronyssinus Trouessart (57.6%), Dermatophagoides farinae Hughes (24.3%) and Dermatophagoides evansi Fain (14.9%) (Acari: Pyroglyphidae), and Cheyletus malaccensis Oudemans (3.2%) (Acari: Cheyletidae). All of the dormitories were contaminated by more than one house dust mites species and the mean density of house dust mites in dormitories was 8.3 ± 0.2 mites/g of dust. There was a significant relationship between average house dust mites density and some of environmental factors such as relative humidity, temperature, floor covering type, and number of occupants (P &lt; 0.05). Results of this study revealed that two major allergenic dust mites, D. pteronyssinus and D. farinae, were the most prevalent and collected from all of dormitories and some of indoor environmental factors found to influence mites’ population.
