Clinical relevance of skin prick test in atopic dermatitis patients at allergy immunology division dermatovenerology outpatient clinic Dr. Soetomo general academic teaching hospital Surabaya

Abstract

Background: Positive specific IgE tests, including skin prick test (SPT), for several food allergens are frequently found in atopic dermatitis (AD) patients, most of which have no clinical relevance and are associated only with atopy. This study aimed to determine the allergic history of AD patients who were subjected to SPT and to determine its clinical relevance. This is a descriptive retrospective study on AD patients who were subjected to SPT from 2017 to 2019 using secondary data. Allergy history, SPT results, and its clinical relevance were collected and analyzed. From a total of 284 AD patients, only 60 patients who were subjected to SPT. Most of the patients had dust allergy (50.0%) and house dust mite (HDM) allergen also had the highest positive SPT result (63.3%). Furthermore, the highest clinical relevance was found in HDM allergen (93.3%). This study shows that most AD patients were allergic to dust. The highest positive SPT result was found in HDM allergen, where ultimately this allergen also had the highest clinical relevance.
