BACKGROUND the role of dust mites (Dermatophagoides pt.) in the pathogenesis of allergic vulvovaginitis is still controversial. Association between this mite and atopic dermatitis, conjunctivitis, rhinitis or asthma is already known. Some authors study the possible relationship between some vulvovaginitis and local hypersensitivity. The aim of this study was to corroborate the allergic aetiolog...

Methods 5 specific igE level measurements (weed, 2 different tree panels [mixture of 5], feathers mix and dermatophagoides pterosyninus[Dp] and dermatophagoides farinae [Df]) and serum total igE levels, serum total eosinophil counts of a total 60 patients with Asthma (21 of them with asthma and allergic rhinitis) aged 19 to 52 (41 female, 19 male) and 34 (20 female, 14 male) healthy persons wer...

Background World Health Organization position paper on immunotherapy recommends using mite allergen vaccines for rhinitis and mild to moderate asthma. Allergic sensitization to domestic mites and particularly to Dermatophagoides pteronyssinus, Dermatophagoides siboney and Blomia tropicalis has been described before in Cuba, as strongly linked to respiratory allergy symptoms. The aim of this wor...

The aim of our study is to find differences in IgG in sera of potentially exposed and nonexposed individuals and to detect differences in concentrations of specific serum IgG among subjects with and without EAA. Seventy-two patients being followed for suspected interstitial lung disease were included. Specific IgG in sera were established by ImmunoCAP. Serum concentrations of Aspergillus fumiga...

Dermatophagoides farinae, as one species of house dust mites, was known to be rich in IgE-reactive components that contribute to allergy in China and worldwide. This study aims to characterize a novel allergen, the D. Farinae-derived Der f 25. In this study, total RNA was extracted from Dermatophagoides farinae and the full-length of Der f 25 gene was amplified by RT-PCR with the primers design...

The aim of this study was to determine the prevalence of sensitization to common allergens in children with allergic rhinitis (AR) living in Qingdao, China. We conducted a retrospective analysis for AR cases, who underwent skin prick tests (SPT) in Qingdao. A total of 2841 children with AR qualified for the inclusion criteria (Age 3-5 years: 1500 children; Age 6-12 years: 1341 children). The mo...

House dust mite (HDM) is a primary allergen in allergic rhinitis (AR) and asthma. Neutrophil apoptosis is associated with allergic diseases and innate immunity to infection. The present study examined how HDM affects constitutive neutrophil apoptosis in normal and AR subjects. Total IgE increased in AR subjects when compared to normal subjects, and patients with AR were HDM-specific IgE positiv...

Se determinó el perfil de sensibilización a aeroalérgenos más comunes en la población Portoviejo, durante periodo noviembre 2017 - 2018. llevó cabo un estudio observacional, descriptivo, carácter retrospectivo y corte transversal, cuyos resultados se obtuvieron base datos del Laboratorio Gamma ciudad Portoviejo. La muestra poblacional estuvo conformada por 112 pacientes que realizaron test RAST...

BACKGROUND AND OBJECTIVE Little is known about the role of molecular diagnosis in house dust mite (HDM) allergy. In this study, we investigated the association between the sensitization profile of adolescent and adult HDM-allergic patients and asthma in a region with high rates of exposure to HDM. METHODS We conducted a cross-sectional study of 384 HDM-allergic patients (38.5%, males; median ...
