Abstract
Unlabelled: As is patch test using crushed live mites and crushed dried dead mites of Dermatophagoides pteronyssinus (D.p.), Dermatophagoides farinae (D.f.), & Tryophagus ptrescentiae (T.p.) was performed on 49 AD patients and 18 control patients suffering from dermatitis other than AD.
Results: 1) with crushed dried dead mites all patients showed negative reactions but with live mites 11 among 49 AD patients were positive (22.4%); 2) female mites were more positive than males at the rate 8:1; 3) with cases positive to mites, (a) D.p. was positive in all 11 positive cases (100%), (b) D.f. was negative in 5 cases (0%), and (c) T.p. was positive in 2 cases among 4 (50%); 4) because of the pathological manifestations of spongiosis and the infiltration of histiocytes and lymphocytes, the possibility of contact allergy to mite elements was suggested, as a mechanism of atopic dermatitis.
