    Growth Arrest-Specific 6 and Cardiometabolic Risk Factors in Patients with Psoriasis

    ObjectivesAn increased risk for cardiovascular disease with psoriasis has been reported. Growth Arrest-Specific 6 (GAS6) amplifies pro-inflammatory endothelial cell activation via TAM receptors. However, it also inhibits inflammation by multiple mechanisms including phagocytosis. The objective of this study was to investigate whether plasma GAS6 levels are associated with conventional cardiometabolic (CM) risk factors in patients with psoriasis. MethodsForty patients diagnosed with psoriasis (22 male, mean age: 43.313.8years) and 40 age-/sex-matched healthy controls (22 male, mean age: 39.38.9years) were included in the study. CM risk factors (hypertension, hyperlipidemia, diabetes mellitus, and cigarette smoking) were identified. GAS6 levels were measured by ELISA. ResultsThere were no significant differences between the plasma GAS6 levels of patients with psoriasis compared to the control group (6.6 +/- 2.0ng/mL, 7.6 +/- 2.8ng/mL, respectively, P>0.05). However, GAS6 levels of patients with psoriasis having a smoking history (n=11) were significantly lower than both patients with psoriasis who had no smoking history (n=29) and controls (5.5 +/- 1.7ng/mL, 6.9 +/- 1.9ng/mL, 7.6 +/- 2.8ng/mL, respectively, P<0.05). Similarly, psoriasis patients with at least one CM risk factor showed lower GAS6 levels compared to subjects without any CM risk factor (5.7 +/- 1.7ng/mL, 7.3 +/- 2.0ng/mL, P<0.01). There was no correlation between the GAS6 level, disease duration or PASI score (r=0.150, -0.150, and P=0.310, 0.398, respectively). ConclusionsThis pilot study provides the first evidence in humans for an association between low plasma GAS6 levels and conventional risk factors in psoriasis. Further large scale, prospective studies are needed to confirm these results.

    Assessment of arterial stiffness and cardiovascular hemodynamics by oscillometric method in psoriasis patients with normal cardiac functions
    (SPRINGER, 2015) SEÇKİN GENÇOSMANOĞLU, DİLEK; Sunbul, Murat; Seckin, Dilek; Durmus, Erdal; Ozgen, Zuleyha; Bozbay, Mehmet; Bozbay, Ayfer; Kivrak, Tarik; Oguz, Mustafa; Sari, Ibrahim; Ergun, Tulin; Agirbasli, Mehmet
    Arterial stiffness is associated with increased cardiovascular risk. Pulse wave velocity (PWV) and augmentation index (AIx) are non-invasive markers for assessment of arterial stiffness. Increased arterial stiffness is associated with atherosclerosis in patients with psoriasis. Previous studies have shown that high neutrophil-to-lymphocyte ratio (NLR) predicts poor cardiovascular outcome. The aim of this study was to evaluate arterial stiffness and cardiovascular hemodynamics by oscillometric method in psoriasis patients with normal cardiac functions. Fifty consecutive patients with the diagnosis of psoriasis and 50 controls were included in the study. NLR was calculated as the ratio of neutrophil count to lymphocyte count. All patients underwent echocardiographic examination. Measurements of arterial stiffness were carried out using a Mobil-O-Graph arteriograph system. Fifty patients with psoriasis (26 male, mean age 43.3 +/- 13.2 years) and 50 controls (33 male, mean age 45.0 +/- 6.1 years) were included into the study. The distribution of cardiovascular risk factors was similar between the two groups, and NLR was significantly higher in patients with psoriasis (2.74 +/- 1.78 versus 1.82 +/- 0.52, p = 0.002). There was a weak correlation between NLR and PASI score without reaching statistical significance (r = 0.300, p = 0.060). While echocardiographic and hemodynamic parameters were comparable between psoriasis and control groups, heart rate was significantly higher in psoriasis group (81.5 +/- 15.1 and 75.2 +/- 11.8 beats/min, p = 0.021). Psoriasis patients had significantly higher AIx and PWV values as compared to controls (25.8 +/- 13.1 versus 17.4 +/- 12.3 %, p = 0.001 and 6.78 +/- 1.42 versus 6.18 +/- 0.80 m/s, p = 0.011, respectively). AI and PWV were significantly associated with psoriasis when adjusted by heart rate (p = 0.005, odds ratio 1.04, 95 % confidence interval 1.01-1.08 and p = 0.035, odds ratio 1.52, 95 % confidence interval 1.02-2.26, respectively). PWV significantly correlated with blood pressure, lipid levels, and several echocardiographic indices. AIx only correlated with left atrial diameter (r = 291, p = 0.040). Linear regression analysis was performed to find predictors of PWV. Central systolic blood pressure, left atrial diameter, and total cholesterol were independent predictors of PWV. PWV and AIx were significantly higher in patients with psoriasis. Assessment of arterial stiffness parameters may be useful for early detection of cardiovascular deterioration in psoriasis patients with normal cardiac functions. Novel inflammatory biomarkers such as NLR may elucidate the mechanism of vascular dysfunction in such patients.
