OBJECTIVE: Psoriasis (PSO) and rheumatoid arthritis (RA) increase cardiovascular diseases (CVD) beyond traditional risk factors. Vascular inflammation has previously been demonstrated to be present in PSO and RA using [18F]-fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) imaging. However, vascular inflammation has not been compared in these two disorders relative to a healthy reference population. Thus, vascular inflammation was quantitatively assessed in patients with PSO (n=10), RA (n=5), and healthy subjects (n=10) using FDG-PET/CT.
METHODS: FDG-PET/CT mean standardized uptake value (SUVmean) was determined slice by slice within the ascending, aortic arch, descending thoracic, suprarenal abdominal, and infrarenal abdominal aorta, and the mean metabolic volumetric product (MVPmean) was then calculated for each aortic subsegment. Plasma lipids and metabolic and inflammatory markers were also assessed.
RESULTS: CVD risk profiles were largely similar across groups. After adjustment for CV risk factors, regional aortic vascular inflammation based on MVPmean was elevated for both PSO (beta coefficients 0.31-1.47, p<0.001) and RA (beta coefficients 0.15-0.69, p<0.05) compared to healthy subjects.
CONCLUSIONS: These observations using FDG-PET/CT to estimate vascular inflammation support epidemiological findings of premature atherosclerosis in PSO and RA. The use of FDG-PET/CT to investigate vascular inflammation across systemic inflammatory diseases warrants further examination in larger study populations.
