AB0531 Prevalence and differences of the metabolic syndrome in patients with psoriatic arthritis and ankylosing spondylitis

Background Metabolic syndrome (MetS) is regarded as one of the extra articular manifestations of psoriasis and psoriatic arthritis (PsA). On the other hand, the data about the MetS prevalence in ankylosing spondylitis (AS) are limited. Objectives To evaluate the differences of MetS in patients with psoriatic arthritis and ankylosing spondylitis and to study the possible relationship of MetS with inflammation biomarkers and patients’ functional status. Methods The study was conducted on 115 AS patients and 103 PsA patients. The patients were investigated for MetS according to the National Cholesterol Education Program. Data regarding MetS (triglycerides, HDL cholesterol, fasting glucose, blood pressure and waist circumference) and inflammatory status (ESR, CRP) were recorded. The general health was evaluated by the Health Assessment Questionnaire (HAQ). Results The prevalence of MetS was significantly higher in PsA (34%) than in AS (14%) (p
