OBJECTIVES: This study hypothesized that there is an association between chronic stress (as indexed by resting amygdalar activity [AmygA]), hematopoietic system activity (HMPA), and subclinical cardiovascular indexes (aortic vascular inflammation [VI] and noncalcified coronary plaque burden [NCB]) in psoriasis (PSO). The study also hypothesized that treatment of PSO would improve these parameters.
BACKGROUND: PSO is a stress-related chronic inflammatory condition that is associated with increased prevalence of subclinical cardiovascular disease (CVD). In individuals without PSO, stress has been linked to CVD through a serial biological pathway that involves the amygdala, hematopoietic tissues, and atherosclerotic plaques.
METHODS: A total of 164 consecutive patients with PSO and 47 healthy volunteers underwent 18-fluorodeoxyglucose positron emission tomography/computed tomography scans for assessment of AmygA, HMPA, and VI, as well as coronary computed tomography angiography scans for quantifying NCB. Furthermore, a consecutive subset of 30 patients with severe PSO (Psoriasis Area Severity Index Score >10) were followed at 1 year to assess the relationship between skin disease improvement and AmygA, HMPA, VI, and NCB.
RESULTS: The PSO cohort was middle-aged (mean age: 50 years), had low cardiovascular risk (Framingham risk score: median: 3) and had mild to moderate PSO activity (median Psoriasis Area Severity Index Score: 5.6). AmygA was higher in patients with PSO compared to volunteer participants. AmygA was associated with HMPA (bone marrow activity: β = 0.20, p = 0.01) and subclinical CVD (VI: β = 0.31, p < 0.001; NCB: β = 0.27, p < 0.001) The AmygA-CVD association was in part mediated by HMPA (VI: 20.9%, NCB: 36.7%). Following 1 year of PSO treatment in those with severe disease, improvement in skin disease was accompanied by a reduction in AmygA, bone marrow activity, and VI, with no progression of NCB.
CONCLUSIONS: In PSO, a chronic inflammatory disease state, AmygA, which is a manifestation of chronic stress, substantially contributes to the risk of subclinical CVD. Additional studies that use psychometric measures of stress are required to explore therapeutic impact.
