Global prevalence of psoriasis is ranging from 0.91 % to 8.5 % [1]. Exact numbers are missing for Slovakia. 1-5% range is the most probable while 2 % is also mentioned as an average prevalence for the European population. There is approximately 110 thousand patients suffering from psoriasis when extrapolating from total population of 5.5 million [2]. Extracutaneous manifestation is observed in 11–30 % of patients after years of solely skin symptoms presentation [3, 4, 5, 6].Objective: To estimate prevalence of psoriatic arthritis among psoriatic patients population visiting dermatology out-patient irrelevant of the disease duration and the treatment regimen. To compare the sensitivity of both tests (ToPAS and PASE) used, evaluate possible PsA risk factors.Methods: This was a prospective, non-interventional, epidemiological, observational study conducted using a survey administered to psoriatic patients by their dermatologists. 10–20 consequent outpatients with psoriasis in each center in 43 regional dermatology officies were screened for the presence of extra-cutaneous symptoms (i.e. joint pain, enthesitis, dactylitis, nail involvement) using questionnaire, developed specificaly for this study, and by the PASE and ToPAS questionnaires. Patients without personal history of PsA and „positivity“ of PASE and/or ToPAS were sent to the center for confirmation / exclusion of the diagnosis by applying CASPAR criteria. Outcomes were statistically processed.Results: 177 (21.8 %) of total of 831 psoriatic patients had PsA. 9 of 177 (5.35 %) has been newly diagnosed. There was almost equal number of men (50.5 %) and women (49.5 %).Plaque psoriasis has been most frequent type – 76.9 %. 43.2 % of PsA patients reported the onset of the disease after 40 years of life.
