	abstract = {OBJECTIVES: To evaluate the prevalence and its clinical characteristics of psoriatic arthritis (PsA) in a specialized psoriasis clinic of a University Hospital.

METHODS: In this retrospective study, 278 patients with psoriasis were evaluated between 2011 and 2013.

RESULTS: The study included 278 patients with psoriasis: 144 (52\%) were male and 134 (48\%) female. Their median age was 51.41 with median psoriasis presenting age of 34.52 years. Referring to the type of psoriasis, 86\% presented with plaque psoriasis, 5\% guttate, 2\% palms and soles, 2\% inverse, 1\% pustular and 4\% with psoriasis of more than one type. Nail disease appeared in 121 patients (43.5\%) and scalp disease in 175 (63\%). Of these patients, 85 (30\%) had PsA, whereas 51\% of patients with PsA had psoriatic nail disease. With reference to the PsA type, 43 (51\%) patients presented with polyarthritis, 10 (12\%) with oligoarthritis, 7 (8\%) with axial arthritis, whereas the rest 25 of them (31\%) had PsA of more than one type. The subgroup of patients with PsA had significantly higher rates of comorbidities including arterial hypertension, diabetes and hypercholesterolaemia compared to non-PsA patients with 41\% vs. 17\% (P = 0.001), 20\% vs. 8\% (P = 0.021) and 41\% vs. 19\% (P = 0.004), respectively.

CONCLUSION: The prevalence of PsA among patients with psoriasis was relatively higher in Greece compared to other ethnic-based studies. Comorbidities related to life expectancy were more frequent. As there is a high percentage of undiagnosed cases with active arthritis among patients with psoriasis, dermatologists should be aware of PsA clinical signs in order to recognize it earlier and provide successful treatment.},
