Skin prick test (SPT) may be useful to detect possible intrinsic and extrinsic triggering factors for atopic dermatitis. In this study, it was aimed to examine patients with atopic dermatitis who underwent SPT. The most common triggering allergens were evaluated and the association between demographic factors, accompanying other allergic disorders and SPT positivity was also investigated. This study was carried out retrospectively by examining the file records of 144 patients who underwent SPT due to atopic dermatitis. The most frequent allergens with at least three positivity were grasses (31.2%), grasses mix (24.3%), Cynodon dactylon (15.3%), D. pteronyssinus (9.7%), D. farinae (7.6%), respectively. D. farinae and D. pteronyssinus positivity were significantly statistically more frequent in patients wi th above 18 years than in patients under 18 years (p values were 0.003 and 0.007, respectively). There were statistically significant differences between at lea st one allergen positivity and allergic rhinitis (p=0.043) while there were no differences betwe en at least one allergen positivity and other allergic conditions including asthma, conjunctivitis, and food hypersensitivity (0.721, 0.927, 0.258). T he most common at least three positive allergens in patients with atopic dermatitis who had accompanyingal lergic rhinitis were grasses (44.5%), grasses mix (37.0%), Cynodon dactylon (27.2%), D. farinae (9.9%), D. pteronyssinus (8.6%). In this study, house dust mites and grass allergens were found to be the most common triggers of atopic dermatitis. In conclusi on, the frequency of food allergens was less common in atopic dermatitis. The most common allergic comorbidity associated with atopic dermatitis was allergic rhinitis, and house dust mites and grasses were the most common allergens in these cases.
