Chemerin as a marker of subclinical cardiac involvement in psoriatic patients
Background: Chemerin has been associated with psoriasis and inflammation, but there are no studies demonstrating an association between chemerin and subclinical cardiac involvement in psoriatic patients. Therefore, the present study aimed to evaluate whether psoriatic patients with increased epicardial fat tissue, impaired flow-mediated dilatation, and diastolic dysfunction have higher serum chemerin levels than a healthy control group.
Methods: The study included 60 psoriatic patients and 32 healthy controls. Echocardiographic parameters, epicardial fat tissue, flow-mediated dilatation, and chemerin levels were recorded for both groups.
Results: The serum levels of chemerin in the psoriatic patients were significantly higher than in the control group. The diastolic function parameters, including isovolumic contraction and relaxation time, E’/A’ (early diastolic mitral annular velocity/late diastolic mitral annular velocity), and E/E’ (early diastolic peak velocity of mitral inflow/early diastolic mitral annular velocity) values, differed significantly between the groups. Epicardial fat tissue was significantly higher and flow-mediated dilatation was significantly lower in psoriatic patients than in the controls. Chemerin was significantly positively correlated with age, body mass index, systolic and diastolic blood pressures, waist circumference, E/E’, and epicardial fat tissue. Serum chemerin was significantly negatively correlated with E’, E’/A’, and flow-mediated dilatation. A multiple linear regression analysis showed that chemerin was independently correlated with E/E’.
Conclusions: Psoriatic patients exhibit early subclinical atherosclerosis and diastolic dysfunction. Chemerin can be used as a marker to screen for patients with subclinical cardiac involvement
Association between galectin-3 levels and isolated coronary artery ectasia
Background: Coronary artery ectasia (CAE) is a well-recognised disorder characterised by abnormal dilation of the coronary arteries. Underlying mechanisms associated with abnormal luminal dilation in CAE remain to be elucidated. However, histopathological features resemble those of coronary atherosclerosis. Galectin-3 (Gal-3) is a valuable biomarker for both progression and destabilisation of atherosclerotic lesions. To the best of our knowledge, there is no study in the literature examining serum Gal-3 levels in patients with isolated CAE. In the present study, therefore, we aimed to investigate the possible relationship between serum Gal-3 levels and isolated CAE
