The patients who were in the acute phase of urticaria, or suffered from dermatographism

, eczema, ichthyosis, etc.) were excluded from the study.

There was no significant difference between c.3321delA and other AD-associated phenotypes, including gender, family history of atopic disorders (data not shown), early age of onset, infraorbital fold, orbital darkening, white dermatographism
, and perifollicular accentuation ( P > 0.05) [Table 1].
mostly result in hemorrhagic bullae.
, if present, would support a diagnosis of urticaria rather than EM.
Participants with no response to histamine and no response to any allergen were excluded, as were participants with dermatographism
, when the response to the negative control was as large as any other response.
SPTs cannot be performed in patients with dermatographism
, or when there is extensive atopic dermatitis or eczema.
