Allergen-specific immunotherapy with house dust mite (HDM) allergen extracts can effectively alleviate the symptoms of allergic rhinitis and asthma. The efficacy of the immunotherapeutic treatment is highly dependent on the quality of house dust mite vaccines. This study was performed to assess the stability of house dust mite allergen vaccines prepared for sublingual immunotherapy. Lyophilized Dermatophagoides pteronyssinus (Dpt) mite bodies were the starting material for the production of sublingual vaccines in four therapeutic concentrations. The stability of the extract for vaccine production, which was stored below 4 ?C for one month, showed consistence in the protein profile in SDS PAGE. ELISA-inhibition showed that the potencies of Dpt vaccines during a 12 month period were to 65-80 % preserved at all analyzed therapeutic concentrations. This study showed that glycerinated Dpt vaccines stored at 4?C preserved their IgE-binding potential during a 12 month period, implying their suitability for sublingual immunotherapeutic treatment of HDM allergy.

AbstractIgE sensitisation in tropical areas is under-reported. A 2 year retrospective cohort study of allergy data specific to aero and food allergens in Brunei demonstrated that specific IgE levels to house dust mite (Dermatophagoides pteronyssinus, D.farinae, Blomia tropicalis) were highest in this population and correlated with atopic dermatitis (p < 0.001). Shrimp and peanut were the most common food allergens. A dominance of house/storage mite sensitization is seen in Brunei which is consistent with other tropical countries.
