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. Skin test with HDMs is well known to cause irritation due to their proteolytic enzymes.The study was undertaken with the objective to study the skin prick test positivity to house dust mites in patients with chronic urticaria<span lang="EN-IN">.</span></p><p class="abstract"><strong>Methods:</strong> The study was done on 56 consecutive patients of clinically diagnosed cases of chronic urticaria attending the OPD. The skin prick test was done according to the standard protocol.<strong></strong></p><p class="abstract"><strong>Results:</strong> We had a total of 56 patients with chronic urticaria, of which males were 30 and females were 26 with a male to female ratio of 1:0.8. Of the 56 patients with chronic urticaria skin prick test to HDM was seen in 8 (14.2%) patients. <em>D. pteronysinnus</em> 6 (10.7%) constituted the majority among the HDM positivity followed by <em>D. farinae</em> 2(3.5%).

Bedding dust is a mixture of many components, of which the house dust mite (HDM) allergen, Der p 1, is the most allergenic. There has been little work to investigate the effect of other bedding dust components on HDM sensitisation. The objective of the study was to determine the effect of endotoxin in bedding dust on the allergic response in HDM-sensitised individuals. Twenty-nine house dust mite-sensitised adults were skin prick and allergen patch tested against a sterile solution of their own bedding dust and against a solution containing the same concentration of Der p 1 as the bedding solution for comparison. There was no significant difference in wheal size between the diluted house dust mite solution and the bedding dust in spite of their high levels of endotoxin. Symptomatic subjects had larger, but not statistically significant, responses to commercial house dust mite solution than asymptomatic subjects. Allergen patch test responses were negative in 22/29 of subjects using either bedding dust solutions or comparable diluted house dust mite solutions. An individual's own bedding dust does not appear to contain factors that enhance skin prick test or atopy patch test responses to house dust mites.

Background Children who grow up in rural areas have a lower incidence of atopy and other allergic manifestations than children in urban areas. Several recent studies have suggested that agricultural exposure may protect children from developing asthma and atopy, but these findings are inconsistent.Objective To examine an association between living in rural or urban areas and skin prick allergy test results in children and to detennine associated risk factors for atopy.Methods We conducted a cross-sectional study in Karo district (rural) and Medan (urban) in October-December 2009. We enrolled primary school children who had a history of atopy in their families. Skin prick testing was done on the volar side of the forearm and included eight aero-allergens: house dust mites, house dust, cotton, chicken feathers, cat dander, cockroaches, mould, and pollen. We analyzed the folloMng risk factors forassociation Mth atopy: tobacco smoke, pets, livestock exposure, and having older sibling(s).Results We recruited 49 children from the Karo district and 52 children from the city of Medan. There were significant associations between living in an urban area and positive skin prick test results for house dust mites and house dust compared to living in a rural area (P=0.04, 95% CI: 1.11 to 5.91; P=0.04, 95% CI: 1.13 to 12.45, respectively). The reverse was true for cockroach allergens (P=0.02, 95% CI: 0.16 to 0.81). Tobacco smoke and livestock exposure were associated Mth negative skin prick test results in rural children (P=O.03, 95% CI: 0.03 to 0.81 and P=0.002, 95% CI: 0.02 to 0.42, respectively). Multivariate analysis revealed that lack of livestock exposure was the major risk factor associated Mth any positive skin prick test results in rural children (P=0.004; 95% CI ; 0.02 to 0.49).Conclusion There were differing associations between living in rural and urban areas to various skin prick test results in children. Lack of livestock exposure was the risk factor associated with positive skin prick test results in rural children.
