OBJECTIVE: To evaluate the prevalence of the metabolic syndrome in patients with rheumatoid arthritis (RA), ankylosing spondylitis (AS), and psoriatic arthritis (PsA).
METHODS: Consecutive patients with RA, AS, or PsA who attended our outpatient arthritis clinics between July and November 2009 were recruited for a study of atherosclerotic risk factors and the metabolic syndrome, defined according to the 2009 joint statements using the Asian criteria for central obesity.
RESULTS: Nine hundred thirty patients were studied (699 with RA, 122 with AS, and 109 with PsA; 70% women, mean ± SD age 51.1 ± 12.7 years). The mean ± SD disease duration for patients with RA, AS, and PsA was 5.3 ± 5.4, 6.0 ± 5.6, and 3.6 ± 3.1 years, respectively. The prevalence of metabolic syndrome was significantly higher in PsA (38%) than RA (20%) or AS (11%; P < 0.001). The odds ratios (ORs) for the metabolic syndrome compared to age- and sex-matched controls were 0.98 (95% confidence interval [95% CI] 0.78-1.23, P = 0.88), 0.59 (95% CI 0.30-1.15, P = 0.12), and 2.68 (95% CI 1.60-4.50, P < 0.001), respectively, for RA, AS, and PsA. Patients with PsA had a significantly higher prevalence of impaired fasting glucose (30%; P < 0.001), low high-density lipoprotein (HDL) cholesterol (33%; P < 0.001), high triglycerides level (21%; P = 0.008), central obesity (65%; P < 0.001), and high blood pressure (56%; P = 0.045). In a logistic regression model, the adjusted OR for the metabolic syndrome in PsA was 2.44 (95% CI 1.48-4.01, P < 0.001) relative to RA or AS. The adjusted ORs for central obesity, impaired fasting glucose, hypertriglyceridemia, and low HDL cholesterol were also significantly higher in PsA patients.
CONCLUSION: Patients with PsA, but not RA or AS, have a significantly higher prevalence of the metabolic syndrome compared to the general population. Among the 3 diseases studied, PsA has the highest prevalence of the metabolic syndrome and is associated with the highest cardiovascular risk.
