There are compelling evidences that house dust mites are important in the pathogenesis of atopic dermatitis. Recently, detection of house dust mite allergens from clothing, skin, and dust from human hair has been reported. To evaluate the importance of house dust mite exposure in the clinical severity of atopic dermatitis, we measured house dust mite allergens(Der f 1 from Dermatophagoides farinae and Der p 1 from D.pteronyssinus) in scalp dander from 27 children with atopic dermatitis and 41 children with asthma only by enzyme-linked immunosorbent assay and examined correlation between house dust mite allergen concentrations in scalp dander and clinical severity of atopic dermatitis in children.
1. Der f 1 was detectable in scalp dander samples of 32 patients(47%) from overall 68 patient and Der p 1 was detectable in 33 patients(49%). House dust mite allergens(Der f 1 or Der p 1) were detectable in scalp dander samples of 46 patients(70%) from overall 68 patient.
2. There was no significant differences in house dust mite allergen levels between atopic dermatitis patients and patients with asthma only
3. The skin reactivities(A/H ratio) to D.pteronyssinus(1.43 Β± 1.01) were significantly higher than those to D.farinae(1.30 Β± 0.85) in 68 patients with either atopic dermatitis or asthma(p<0.05). The concentrations of Der f 1 in scalp dander extract(2.65 Β± 5.88 ng/ml) were significantly higher than those
concentration of Der p 1(0.39 Β± 1.07 ng/ml)(p<0.05).
4. There was a tendency of inverse correlation between frequency of scalp washing and concentration of Der f 1 in scalp dander extract(r=-0.24, p=0.052).
5. There was a significant correlation between severity grade of atopic dermatitis and concentration of Der f 1 in scalp dander(r=0.39, p<0.05) in 27 children with atopic dermatitis. However, there was no significant correlation between severity grade of atopic dermatitis and concentration of Der p 1 in scalp
dander(r=-0.05, p>0.05).
There was a significant correlation between house dust mite allergen concentrations in scalp dander and clinical severity in children with atopic dermatitis. And these results suggest that exposure to house dust mite allergen is important in the pathogenesis of atopic dermatitis.restrictio
