Clinical Features Of Psoriatic Arthritis: 17 Cases / 대한류마티스학회지

ABSTRACT

OBJECTIVES: To investigate the clinical, laboratory and radiological features of psoriatic arthritis. METHODS: Seventeen patients with psoriatic arthritis were studied. The diagnosis of psoriatic arthritis was based on the presence of an inflammatory arthritis associated with psoriasis, usually seronegative. Other rheumatic conditions were excluded. RESULTS: 1) There were 8 men and 9 women(male to female ratio of 1:1.13) and mean age was 41 years old. 2) Thirteen patients developed arthritis an average of 7. 3 years after the onset of psoriasis ; Three had a simultaneous onset of skin and joint disease(within 6 months), while in one patient the arthritis preceded psoriasis by a 10 years. 3) Ten patients had nail lesions, and dactyliris was presented in 6 patients. 4) The frequency of positive rheumatoid factor was 18 percent of the patients, and HLA-B27 was detected in 24 percent. 5) The prevalences of clinical patterns were as follows : oligoarthritis(41.2%), polyarthritis(29.4%), spondyloarthritis(23.5%) and arthritis in distal joint (5.9%). CONCLUSIONS: In contrast to rheumatoid arthritis, psoriatic arthritis occured frequently in males as in females and oligoarthritis was the most common joint pattern.
