Dust vacuum samples collected for allergen analysis were analyzed for two dust mite allergens, Dermatophagoides pteronyssinus
allergen 1 (Der p 1) and Dermatophagoides farinae allergen 1 (Der f 1), and cockroach allergen Blattella germanica allergen 1 (Bla g 1).
In New Zealand 98% of house dust mites are Dermatophagoides pteronyssinus
Allergic sensitization was defined by skin-prick tests to 11 allergens in EGEA (cat, Dermatophagoides pteronyssinus
, Blattela germanica, olive, birch, Parieteria judaica, timothy grass, ragweed pollen, Aspergillus, Cladosporium herbarum, Alternaria tenuis) and by specific IgE to four allergens in ECRHS (cat, Dermatophagoides pteronyssinus
, Cladosporium, and timothy grass).
mites and Dermatophagoides farinae mites, house dust, and American cockroach rounded out the 14 antigens.
Skin prick testing was performed with grass pollen (25 g/L), Dermatophagoides pteronyssinus
(12 g/L), cat fur ([10.
The main mite allergen, Dermatophagoides pteronyssinus
1, is a digestive enzyme produced by the mite and excreted in dry, brittle fecal pellets (6).
We measured atopy by using skin prick tests to inhalant allergens Dermatophagoides pteronyssinus
(HDM), Dermatophagoides farina (also HDM), cockroach, cat, Alternaria, Aspergillus, rye grass, and a grass mix (Hollister-Stier, Spokane, WA, USA), as previously described (Peat et al.
Consistent with our earlier investigation, we used a two-group pretest/post-test methodology in which patients were challenged with either the active antigen for Dermatophagoides pteronyssinus
or a placebo suspension.
The active ingredient being considered is a combination of the major allergens of Dermatophagoides pteronyssinus
, Der p 1 and Der p 2, expressed as a single recombinant molecule.
