BACKGROUND The increasing trend in allergic diseases has become obvious in the present day, especially in developing countries like India, because of many factors such as change in ambient air quality, increased air pollution, metamorphic change in living habits and lifestyle, and climate.1 Mites present in house dust represent a major source of allergens, resulting in different allergic manife...

BACKGROUND Different in vivo methods are used to quantify the amount of allergens in products for skin prick testing. It is unclear how this impacts on the correct diagnosis of allergies. AIM OF THE STUDY We compared the allergenic potency of three commercial extracts for skin prick testing and evaluated batch-to-batch differences within each product. METHODS Patients with a mono-sensitizat...

The residual effect of a commercial spray containing 2.0% benzyl benzoate against Dermatophagoides pteronyssinus was evaluated in the laboratory. Filter papers treated with benzyl benzoate were dried for 2 hours and placed in Petri dishes. Adult mites were then added and mortality was assessed following 24 hour contact and at succeeding 4 weeks intervals up to week 28 post-treatment using the s...

Background Immunotherapy with mite allergens is effective both in rhinitis and asthma. However, injection immunotherapy carries a high risk of systemic adverse events, so, the sublingual route (SLIT) is being used more frequently. Efficacy of SLIT in asthma has been widely studied, however, in Cuba, the therapeutic effect of mite vaccines of Dermatophagoides pteronyssinus (Dp), D.siboney (Ds) a...

Methods A randomized, double-blind, placebo-controled, parallelgroup, phase II study was conducted. Thirty-six subjects with LAR to DP were randomized to receive Pangraminâ PLUS, ALK, Dermatophagoides pteronyssinus (AIT-DP) or placebo for 24 months. The primary endpoint was total symptoms (TSS) and total medication scores (TMS). Secondary endpoints included: total combined symptom+medication sc...

Sixty-nine children with moderately severe perennial asthma were submitted to bronchial provocation tests using aqueous extracts of Dermatophagoides pteronyssinus (house dust mite). 60 (87%) had immediate positive reactions. 73% also had late reactions occurring 4 to 8 hours after the challenge. A significant correlation was found between frequent attacks of asthma in the year before bronchial ...

The house dust mite (HDM) is globally ubiquitous in human habitats. Thirty-two allergens for Dermatophagoides farinae and 21 pteronyssinus have been detected so far. present minireview summarizes information about the role of Der p 1 as a key coordinator HDM-induced allergic response reports on series Italian patients who are to HDMs. We studied specific IgE profiles population with asthma rhin...
