Objectives The aim of this study was to determine the types of rheumatic manifestations in psoriasis patients and their correlation with psoriasis skin and nail lesions. Background The characteristic of inflammatory arthropathy associated with psoriasis is termed psoriatic arthritis (PsA) and is placed in a group known as seronegative spondyloarthropathies. Materials and methods In all, 100 patients with psoriasis were included in this study. They were divided according to the presence of rheumatic manifestations: patients with no rheumatic manifestations, patients with PsA, and patients with other rheumatic manifestations. Disease assessment scores such as the Psoriasis Area and Severity Index score for psoriasis severity and the Moll and Wright criteria for the PsA type were used. Results Forty-two percent had no rheumatic manifestations, 40% had PsA according to CASPAR criteria, and 18% had other rheumatic manifestations. In the PsA group, 57.5% had spondyloarthritis, 20% had a distal interphalangeal joint, 7.5% had polyarthritis, 10% had oligoarthritis, and 5% had arthritis mutilans. Clinical sacroiliitis occurred in 18% of the psoriasis patients and in 45% with PsA. Axial arthritis occurred in 21% of the psoriasis patients and in 52.5% with PsA. Clinical enthesitis occurred in 27% of the psoriasis patients and in 55% with PsA. Dactylitis occurred in 4% of the psoriasis patients and in 10% with PsA. Peripheral arthritis occurred in 20% of the psoriasis patients and in 42.5% with PsA. Distal interphalangeal arthritis occurred in 7% of the psoriasis patients and in 17.5% with PsA. Conclusion The prevalence of PsA was 40% in the studied patients with psoriasis, and the most prevalent type of PsA was spondyloarthritis. PsA occurred most commonly at an older age and with a longer duration of psoriasis. The most prevalent rheumatic manifestations were arthralgia, enthesitis, axial arthritis, sacroiliitis, and peripheral arthritis.
