Background Psoriatic arthritis (PsA) is a chronic progressive inflammatory disease characterized by peripheral arthritis, dactylitis, axial joint involvement and extraarticular features. Disease consequences such as chronic pain, severe joint damage and fatigue may adversely effect on a patient's physical function and health-related quality of life (QoL) to perform daily activities.

Objectives The aim of this study was to investigate the potential relationship between physical function and health-related QoL and disease activity measures in patients with PsA.

Methods For all participating patients, quality of life, functional and disease activity measures were measured by different ways: Nottingham Health Profile (NHP), psoriatic arthritis quality of life (PsAQoL), Ankylosing Spondylitis Quality of Life (ASQoL), SF36 health survey, Health Assessment Questionnaire (HAQ), BASFI, VAS pain, DAS28, BASDAI and acute phase markers including ESR and CRP.Patients with PsA were discriminated into low and high disease activity according to BASDAI (≥6 vs ≤4).

Results A total of 186 patients with PsA (116 female, 70 male, mean age 43,9±12,6) who met CASPAR criteria were included. Their mean symptom duration was 7.9±9.1 years. Patients with higher BASDAI score (≥6) had significantly higher scores on all important items including health related QoL, fatigue, pain, and functional status. Correlation coefficients between disease activity and various health related QoL measurements were given in Table1. SF36 physical component score was significantly correlated with VAS-pain, BASDAI and DAS28 compared to SF36 mental component. Also, physical activity subscore of NHP was found higher correlated with disease activity indices for PsA in all NHP sections. Other quality of life measurements including PsQoL, HAQ and ASQoL were also significantly correlated with disease activity measurements.

Conclusions Psoriatic arthritis has a major impact on patients' lives. Variable disease activity measurements were found correlated with all important QoL measurementss including NHP, SF36, PsQoL, HAQ and ASQoL. In patients with PsA, high disease activity may lead to severe impairments in daily activities and influence on participation in society.
