The relationship between level of anti-CCP, clinical activity and quality of life in patients with psoriatic arthritis

Objectives: Psoriatic arthritis (PsA) is an inflammatory joint disease. The aim of this study was to investigate the titers of Anti-syclic citrullinated protein (anti-CCP antibodies) in PsA and assess their associations with clinical characteristics and quality of life. Materials and methods: Fourty two patients with PsA and 38 healthy control subjects were included. Demographic data and clinical characteristics including age, gender, disease duration, and erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), anti-CCP antibodies and rheumatoid factor were assessed. Visual analog scale (VAS), Nottingham Health Profile (NHP) and short form-36 (SF-36) were used to evaluate QOL in both groups. Results: The demographic data of the subjects were not different between the groups. Patients with PsA had higher anti-CCP levels compared to healthy controls (56.3±73.0 U vs. 0.9±0.5 U, respectively, p=0.01) Thirteen (33.3%) patients with PsA had positive anti-CCP, while no anti-CCP positivity was found in the control group (p
