Results Mean age of study population was 47.5+/-13.4 years. Out of 200 patients, 94 [47%] were male and 106 [53%] were female. 79 [39.5%] patients had PsA: oligoarthritis 26 [37%], symmetric 24 [34%], axial joint involvement 18 [25%], classical distal interphalangeal [DIP] 6 [8%] and arthritis mutilans 5[7 %]
