Results Of Skin Prick Tests In Dermatology Outpatient Allergy Unit

Objective: Skin prick test (SPT) is mainly used for diagnosis and follow-up of diseases like atopic dermatitis (AD), chronic urticaria (CU), allergic asthma (AA) and allegic rhinitis (AR). The aim of current study is to explore the results of SPT retrospectively which were performed in Dermatology Outpatient Allergy Unit (DOAU) for identifying indications and positivity.Methods: Results of SPT which were performed on 2014-2016 were investigated based on archives of DOAU. Results of SPT were analyzed from the SPT Forms which were prepared for each patient.Results: SPT were performed on 1916 individuals who admitted to DOAU during 2015-2016. AA was determined in 941, AR in 133 and dermatological diseases were 842 patients. SPT positive results, for at least one or more allergen agents, of patients with AA, AR and dermatological diseases were 92.1%, 71.4% and 50% respectively. Dermatological diseases included; except CU in 69 patients and AD in 55 patients. In the remaining 718 patients were diagnosed with dermatitis, idiopathic generalised pruritus (IGP) and other dermatological disorders. SPT positivity rates in CU was 55.1%, 52.7% in AD and 48.6% in several dermatological diseases.Conclusions: As a result, the rate of SPT positivity in patients with AA and AR were higher than both CU, AD and several dermatological diseases. The reason of this may be related with lesser role of type 1 hypersensivity reaction in etiopathogenesis of CU and AD, and/or improper SPT indications who were directed with diagnosis of several dermatological diseases.
