[A study on preventive effects of mite allergens by specially-fabricated futons with anti-mite treatments].
BACKGROUND
The purpose of this study was to investigate effects of specially-fabricated futons (beds) with anti-mite treatments on reductions of mite allergens (Der p.1 and Der f.1) and serum IgE antibodies against Dp (Dermatophagoides pteronyssinus), Df (Dermatophagoides farinae) and house dust1.


METHODS
The futons made by microfibers (Madoromi: M) and phenolic polymer grafted microfine fibers (Madoromi+ALLER BUSTER: M+A) were used. Three groups of student and nurse subjects were asked to use general woolen cotton futons, and the (M) and (M+A) futons for 11 months, respectively.


RESULTS
After the 11 months, the ratios of Der p.1+f.1 allergens in the futons (M) and (M+A) to those in the control futon were 1/3.8 and 1/42.0, respectively, on average. The prevalence of serum IgE antibodies against Dp, Df and house dust1 was found to decrease from 46.7 to 6.7% for the group using the (M+A) futon.


CONCLUSIONS
These results suggested the specially-fabricated futons with anti-mite treatments could effectively reduce mite allergens compared to those made from woolen cotton.
