[The relationship between the density of house dust mite allergens in bedroom and the attacks of allergic rhinitis].

OBJECTIVE: To investigate the relationship between the density of house dust mites allergens in bedroom and the attacks of allergic rhinitis in patients sensitive to mite. METHOD: Seventy-five houses (35 patients with allergic rhinitis and 30 healthy controls) were visited for dust sampling from mattresses, sofas, beddings and pillows. Der p1 and Der f1 levels were measured by ELISAs. RESULT: Der p1 and Der f1 levels in healthy control group were significantly higher than levels in patient group(P < 0.05). CONCLUSION: The amount of mite allergens might not be the determining factor for allergic rhinitis sensitization.
