background: dermatophagoides farinae and dermatophagoides pteronyssinus are house dust mites (hdm) that they cause severe asthma and allergic symptoms. tropomyosin protein plays an important role in mentioned immune and allergic reactions to hdms. here, tropomyosin protein from dermatophagoides spp. was comprehensively screened in silico for its allergenicity, antigenicity and similarity/conser...

Methods We realized a 2 years ambispective study for assessment safety and efficacy of subcutaneous immunotherapy with a dust mite vaccine with the adjuvant L-tyrosine. We reviewed the data of 292 patients with allergic rhinitis and/or asthma. They are sensitized to Dermatophagoides pteronyssinus or Dermatophagoides farinae and or Blomia tropicallis. A data base was constructed to allow complet...

AIM Determination of prevalence of sensitization to Dermatophagoides pteronyssinus, Dermatophagoides farinae (pyroglyphid mites), Lepidoglyphus destructor, and Tyrophagus putrescentiae (non-pyroglyphid mites) in urban continental Croatia. METHODS Specific IgE (sIgE) and skin prick test (SPT) for D. pteronyssinus, D. farinae, L. destructor, and T. putrescentiae were performed in 67 men. SPT wa...

RESULTS: Fifty patients (68.5%) had positive skin test responses. There were positive responses to D. pteronyssinus (52.0%), B. tropicalis (53.4%), T. putrescentiae (15.0%), E. maynei (12.3%), L. destructor (8.2%), B. germanica (20.5%), P. americana (21.9%), Felis catus (10.9%), C. herbarium (2.7%), A. alternata (4.1%), and P. notatun (1.3%). The exposure to mite and cockroach allergens was sim...

Background House Dust Mites are important etiological agents of respiratory allergy. Allergen mixtures are often used for specific immunotherapy in polysensitized patients, although scientific evidence to support its efficacy, safety and stability is scarce. Sublingual immunotherapy (SLIT) is being gradually accepted as an alternative to conventional subcutaneous immunotherapy. For SLIT, higher...

Twenty-five patients with perennial rhinitis and a positive skin prick test (SPT) for Dermatophagoides pteronyssinus (Dp) and Dermatophagoides farinae (Df) were submitted to nasal provocation and the radioimmunosorbent test (RAST) for specific IgE-antibodies. We found a significant correlation in the reaction to both allergen extracts for all parameters examined. In addition, there was a signif...

OBJECTIVE To evaluate hypersensitivity to Dermatophagoides pteronyssinus (D. pteronyssinus) and Dermatophagoides farinae (D. farinae) in pediatric patients with asthma, and the use of acaricides. METHODS This is a randomized controlled trial in 82 asthmatic children. They were recruited and evaluated for severity and chronicity according to the Global Initiative for Asthma Guidelines. The s...

CONTEXT AND OBJECTIVE Knowledge of the profile of allergen sensitization among children is important for planning preventive measures. The objective of this study was to assess the prevalence and profile of sensitization to inhaled allergens and food among children and adolescents in an outpatient population in the city of Palmas. DESIGN AND SETTING Cross-sectional study at outpatient clinics...
