Serum biomarkers in patients with psoriasis and coronary artery disease and their impact on hospitalization: data form a prospective, 4-year, single-center, uncontrolled study

Aim. To study serum biomarker profile in patients with coronary artery disease (CAD) and psoriasis and the impact on the incidence of hospitalization for cardiovascular reasons and psoriasis.Material and methods. The study included 90 patients divided into following 3 groups: with psoriasis (n=30), coronary artery disease (CAD) (n=30) and CAD+psoriasis (n=30) in whom serum biomarkers were determined at the beginning of the study (growth stimulation expressed gene 2, N-terminal pro-brain natriuretic peptide (NT-proBNP), interleukin-17 and tumor necrosis factor alpha) and hospitalization rates were monitored over 4 years.Results. There was a significant difference in the concentrations of all biomarkers between the groups (p<0,05), with the maximum values being in the CAD+psoriasis group, except for NT-proBNP. In regression analysis, risk factors for cardiovascular hospitalizations were psoriasis (p=0,049) and increased NT-proBNP concentrations (p<0,001).Conclusion. Comorbidity leads to an increase in the serum concentration of biomarkers, while the risk factors for cardiovascular hospitalization were psoriasis and serum NT-proBNP level.
