Tungau Debu Rumah (TDR) merupakan salah satu substansi alergen yang dapat memicu reaksi alergi. Keberadaan TDR dikaitkan dengan manifestasi alergi pada saluran pernafasan dan kulit. Pengabdian ini bertujuan mengetahui hasil pemeriksaan TDR pada debu kasur di Pondok Pesantren Attamadun Kota Batam. Metode Pemeriksaan yang digunakan dengan teknik  flotasi. Pemeriksaan TDR dilakukan pada 20 sampel debu kasur santri di Pondok Pesantren Attamadun Kota Batam. Hasil pemeriksaan  diperoleh, 15 (75%) sampel positif TDR dari 20 sampel yang di periksa. Spesies TDR yang ditemukan, yaitu Dermatophagoides pteronyssinus sebanyak 18 (46%) ekor TDR, Dermatophagoides sp sebanyak 15 (39%) ekor TDR dan Dermatophagoides farinae sebanyak 6 (15%) ekor TDR. Hasil perhitungan kepadatan TDR diperoleh rerata kepadatan TDR adalah 22,85 tungau/gram debu, dengan kategori rendah. Berdasarkan hasil yang diperoleh diharapkan kepada pengurus Pesantren Attamadun agar mengedukasi kepada santri untuk merawat kasur dan menjaga kebersihan kamar agar tidak menjadi tempat perkembangbiakan TDR, melakukan pemeriksaan kesehatan rutin santri.

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 < 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.

Allergies in dogs have become a relatively frequent topic of discussion in veterinary surgeries. Many dogs, both purebred and of mixed breeds, are diagnosed for allergies. Allergies have many causes, from genetic predisposition to the environmental conditions in which the animal lives. Allergies in dogs are troublesome because they can lead to serious health complications when diagnosed late or left untreated. The results of the study support the hypothesis that the percentage of allergies to individual allergens varied by region (Tab. 4). Differences were observed in the case of Dermatophagoides pteronyssinus and Dermatophagoides farinae house dust mites, Acarus siro, and Tyrophagus. The remaining allergens caused allergic reactions in similar percentages of dogs from northern, central and southern Poland.

House dust mite was one of the most common allergens in homes around the world and associated with manifestations of allergies of skin and respiratory tract such as bronchial asthma, allergic rhinitis, and atopic dermatitis. This arthropod was commonly found on carpets, mattresses, children's toys, and other home furnishings. This study was aimed to identify and quantify the number of Dermatophagoides spp in Detention Center. This descriptive study was conducted using flotation method on 52 samples of mattress dust collected in February 2020. The results showed that 49 out of 52 mattress dust samples were positive of Dermatophagoidesspp..Of all Dermatophagoides spp, there were Dermatophagoides pteronyssinus (71.2%) and Dermatophagoides farinae (28.8%). In conclusion, this study found two species of Dermatophagoides spp. in Detention Center and suggested that the fascility maintain the cleanliness of the mattress by drying the mattress and changing the sheets at least once a week.

Аллергические заболевания представляют серьезную проблему современной медицины. Сенсибилизация к ингаляционным аллергенам является одним из ключевых факторов формирования респираторных аллергозов. Среди аэроаллергенов важное значение играют аллергенные компоненты домашней пыли – клещи Dermatophagoides pteronyssinus и Dermatophagoides farinae, составляющие до 90% акарофауны жилых помещений. В формировании сенсибилизации к клещам домашней пыли также предполагается роль индивидуальных источников аллергенов. Сенсибилизация к мажорным компонентам аллергена клещей домашней пыли ассоциируется с риском развития бронхиальной астмы, к минорным (Der p 10) – риском развития перекрестных реакций с тропомиозином других беспозвоночных, тропомиозином человека. Аллергены клещей домашней пыли (Der p 2 и Der f 2) могут быть ответственны за симптомы оральной клещевой анафилаксии, а также способствовать развитию сенсибилизации к бактериальным антигенам Staphylococcus aureus и Escherichia coli. В 1 части статьи изложены биология и источники клеща домашней пыли. Представлена классификация аллергенов, пути сенсибилизации и распространенность сенсибилизации к клещу домашней пыли у детей.

Introduction: Allergic rhinitis (AR) is an inflammatory disease of the nasal mucosa that can be modeled using Controlled Allergen Exposure Facilities (CACF). Recently, we clinically validated the house dust mite (HDM) Environmental Exposure Unit (EEU) facility. In the current study, we aimed to assess biological responses in the blood following HDM exposure in the HDM-EEU.Methods: Fifty-five participants passed a screening visit, where they provided consent and completed a skin prick test (SPT), then attended a modest or higher HDM exposure session. Baseline and post-exposure blood samples were collected. Complete blood counts with differentials were measured, and isolated serum was used to determine Dermatophagoides farinae- and Dermatophagoides pteronyssinus-specific IgE (sIgE) and cytokine concentrations (IL-4, IL-5, IL-6, IL-10, IL-13, TNF-α).Results: HDM-allergic participants had significantly greater SPT wheal sizes than healthy controls. sIgE concentrations were significantly greater in allergic participants, with a strong correlation between Dermatophagoides farinae and Dermatophagoides pteronyssinus. Serum eosinophil counts were significantly decreased post-exposure for allergic participants. White blood cell, neutrophil, and lymphocyte counts were significantly increased for both allergic and non-allergic participants post-exposure. Serum IL-13 concentrations were significantly reduced post-exposure in allergics while TNF-α was significantly reduced in non-allergics.Conclusion: The HDM-EEU is a useful model for investigating biologic mechanisms of HDM-induced AR. Allergic participants produced measurable biological changes compared to healthy controls following allergen exposure, specifically with serum expression of eosinophils and related markers, namely IL-5, which promotes the proliferation and differentiation of eosinophils, and IL-13, a cytokine released by eosinophils. The exact mechanisms at play require further investigation.
