Assessment of anti-psoriatic activity of bakuchiol-loaded solid lipid nanoparticles-based gel: design, characterization, and mechanistic insight via NF-kB signaling pathway. NAUNYN-SCHMIEDEBERG'S ARCHIVES OF PHARMACOLOGY 2023; 396:2105-2125.

Abstract
The aim of the current study is to evaluate the anti-psoriatic potential of bakuchiol (Bak) loaded solid lipid nanoparticles (SLNs) via modulating inflammatory and oxidative pathways. Bak-loaded SLNs were prepared using hot homogenization method and characterized by various spectroscopic techniques. Bak-SLNs suspension was formulated into gel using Carbopol. Different in vivo assays were executed to explore the role of inflammatory markers and oxidative enzymes in psoriasis. DLS (dynamic light scattering) analysis showed suitable particle size, zeta potential, and polydispersity index (PDI) of developed formulation. TEM (transmission electron microscopy) reveal the spherical shape of Bak-SLNs particles. The release studies confirmed the sustained release of Bak-SLNs-based gel. UV-B-induced psoriatic Wistar rat model showed significant anti-psoriatic effect of Bak via regulating inflammatory markers (NF-kB, IL-6, IL-4, and IL-10) and levels of anti-oxidant enzymes, superoxide dismutase (SOD), catalase (CAT), glutathione (GSH), and glutathione-S-transferase (GST). Furthermore, RT-qPCR analysis confirms that Bak downregulates the expression of inflammatory markers, while histology and immunohistology results also confirm the anti-psoriatic effect of Bak. The study indicates that Bak-loaded SLNs-based gel significantly downregulates the level of cytokines and interleukins involve in NF-kB signaling cascade; hence, it can prove to be a novel therapeutic approach to cure psoriasis.

Abstract
Background Psoriasis is a chronic inflammatory skin disease. Dyslipidemia may be a risk factor of psoriasis. But the causal relationship between psoriasis and blood lipid still remains uncertain. Methods The two data of blood lipid were obtained from UK Biobank (UKBB) and Global Lipid Genetics Consortium Results (GLGC). The primary and secondary database were from large publicly available genome-wide association study (GWAS) with more than 400,000 and 170,000 subjects of European ancestry, respectively. The psoriasis from Finnish biobanks of FinnGen research project for psoriasis, consisting of 6,995 cases and 299,128 controls. The single-variable Mendelian randomization (SVMR) and multivariable Mendelian randomization (MVMR) were used to assess the total and direct effects of blood lipid on psoriasis risk. Results SVMR estimates in primary data of blood lipid showed low-density lipoprotein cholesterol (LDL-C) (odds ratio (OR): 1.11, 95%, confidence interval (CI): 0.99-1.25, p = 0.082 in stage 1; OR: 1.15, 95% CI: 1.05-1.26, p = 0.002 in stage 2; OR: 1.15, 95% CI: 1.04-1.26, p = 0.006 in stage 3) and triglycerides (TG) (OR: 1.22, 95% CI: 1.10-1.35, p = 1.17E-04 in stage 1; OR: 1.15, 95% CI: 1.06-1.24, p = 0.001 in stage 2; OR: 1.14, 95% CI: 1.05-1.24, p = 0.002 in stage 3) had a highly robust causal relationship on the risk of psoriasis. However, there were no robust causal associations between HDL-C and psoriasis. The SVMR results in secondary data of blood lipid were consistent with the primary data. Reverse MR analysis showed a causal association between psoriasis and LDL-C (beta: -0.009, 95% CI: -0.016- -0.002, p = 0.009) and HDL-C (beta: -0.011, 95% CI: -0.021- -0.002, p = 0.016). The reverse causation analyses results between psoriasis and TG did not reach significance. In MVMR of primary data of blood lipid, the LDL-C (OR: 1.05, 95% CI: 0.99-1.25, p = 0.396 in stage 1; OR: 1.07, 95% CI: 1.01-1.14, p = 0.017 in stage 2; OR: 1.08, 95% CI: 1.02-1.15, p = 0.012 in stage 3) and TG (OR: 1.11, 95% CI: 1.01-1.22, p = 0.036 in stage 1; OR: 1.09, 95% CI: 1.03-1.15, p = 0.002 in stage 2; OR: 1.07, 95% CI: 1.01-1.13 p = 0.015 in stage 3) positively correlated with psoriasis, and there had no correlation between HDL-C and psoriasis. The results of the secondary analysis were consistent with the results of primary analysis. Conclusions Mendelian randomization (MR) findings provide genetic evidence for causal link between psoriasis and blood lipid. It may be meaningful to monitor and control blood lipid level for a management of psoriasis patients in clinic.

Abstract
Psoriasis and coronary artery disease (CAD) are related comorbidities that are well established, but whether a genetic basis underlies this is not well studied. We apply trans-disease meta-analysis to 11,024 psoriasis and 60,801 CAD cases, along with their associated controls, identifying one opposing and three shared genetic loci, which are confirmed through colocalization analysis. Combining results from Bayesian credible interval analysis with independent information from genomic, epigenomic, and spatial chromatin organization, we prioritize genes (including IFIH1 and IL23A) that have implications for common molecular mechanisms involved in psoriasis and CAD inflammatory signaling. Chronic systemic inflammation has been associated with CAD and myocardial infarction, and Mendelian randomization analysis finds that CAD as an exposure can have a significant causal effect on psoriasis (OR = 1.11; p = 3×10-6) following adjustment for BMI and waist-hip ratio. Together, these findings suggest that systemic inflammation which causes CAD can increase the risk of psoriasis.

Abstract
Human serum paraoxonase-1 (PON-1) is a critical antioxidant defense system against lipid oxidation. Decreased PON-1 activity has been associated with systemic oxidative stress in several disease states. We conducted a systematic review and meta-analysis of plasma/serum concentrations of PON-1 paraoxonase and arylesterase activity in psoriasis, a chronic immune-mediated and inflammatory skin disease. The electronic databases PubMed, Web of Science, and Scopus were searched from inception to November 2021. In total, 14 studies in 691 psoriatic patients and 724 healthy controls were included in the meta-analysis. Serum paraoxonase activity was significantly lower in psoriatic patients (SMD = - 2.30, 95% CI - 3.17 to - 1.42; p < 0.001); however, no significant between-group differences were observed in serum arylesterase activity (SMD = - 0.34, 95% CI - 0.11 to 0.80; p = 0.14). The pooled SMD values were not substantially altered in sensitivity analysis. There was no publication bias. In conclusion, our meta-analysis has shown that serum paraoxonase, but not arylesterase, activity is significantly lower in psoriasis, suggesting an impaired antioxidant defense in these patients.

AntiTNF-alpha therapy normalizes levels of lipids and adipokines in psoriatic patients in the real-life settings. Sci Rep 2021; 11:9289. [PMID: 33927259 PMCID: PMC8085202 DOI: 10.1038/s41598-021-88552-6] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2021] [Accepted: 03/15/2021] [Indexed: 11/23/2022] Open
Abstract
Studies have shown that the levels of pro-inflammatory adipokines in patients with psoriasis are higher than in general population. The aim of the study was to investigate the influence of 36-month therapy with TNF-α inhibitors (adalimumab, etanercept, infliximab) on the levels of adipokines (resistin, adiponectin, leptin) and lipids (TG, cholesterol, LDL, HDL) in 37 psoriasis patients and 30 healthy controls. The mean serum concentrations of adiponectin in patients from adalimumab, etanercept and infliximab group were similar to control group (p > 0.05, 142.71, 164.32, 129.35 and 174.44 μg/ml respectively). Resistin levels were higher in patients (p < 0.05, 4.48, 4.53 and 3.39 ng/ml respectively) than in controls (3.05 ng/ml). Mean leptin concentrations were significantly higher (p < 0.05) in the study group than in subjects without psoriasis (428.61, 523.24, 755.27 and 154.10 pg/ml respectively). A significant decrease in the mean resistin concentration was observed under the influence of biological therapy (p < 0.05). Decrease in serum leptin level was noted in etanercept and infliximab groups (p = 0.001 and p = 0.002 respectively). Improvement in all lipidogram parameters was noted in all examined groups (p < 0.05). Results may prove that biologic therapy affects the systemic inflammation associated with psoriasis and this effect persists with long-term therapy.

Abstract
Background and objective Low adiponectin levels have been described in conditions with high cardiometabolic risk, including obesity, type 2 diabetes, insulin resistance, and hyperlipidaemia. Psoriasis is a chronic inflammatory skin disorder, and it is also associated with these conditions. In this study, we sought to assess the correlation between adiponectin levels and these risk factors including psoriasis severity. We investigated adiponectin value and its correlation with components of metabolic syndrome (MetS) and psoriasis severity. Methods Serum adiponectin levels were obtained from 215 psoriasis patients in a tertiary dermatology centre in Singapore. Psoriasis severity was measured with the psoriasis area and severity index (PASI), and cardiometabolic risk factors including obesity, hyperlipidaemia, insulin resistance, and waist circumference were measured. Patients answered a questionnaire regarding alcohol use, exercise, family history, smoking, and treatment history. Results Low adiponectin value was found in psoriasis patients with high body mass index (BMI) risk, high low-density lipoprotein (LDL), and low high-density lipoprotein (HDL). Patients with low HDL value had 25% lower adiponectin value compared to those with normal HDL. Adiponectin levels had a negative correlation with waist circumference. Psoriasis patients with MetS and a family history of cerebral vascular accidents (CVAs) had 17% and 18% lower adiponectin values than those without, respectively. There was no correlation between adiponectin level and PASI score. Conclusion Adiponectin levels were significantly decreased in psoriasis patients with obese-level BMI, MetS, increased abdominal girth, low HDL, high LDL, and a family history of CVA. Low adiponectin levels could play a role in predicting the development of MetS and possibly enable intervention to decrease the risk of cardiovascular mortality in psoriatic patients.

Abstract
Psoriasis is a chronic inflammatory disease of the skin. The new era of biological therapies initiated a shift in the definition of the disease therapeutic success, however, recent reports in the literature draw attention to the treatment-induced weight gain in psoriatic patients. Therefore, it is worth considering the body mass index influence on the biological treatment of chronic plaque psoriasis, seeing that it has manifold associations with the disease and may play an important role in clinical practice management.

Abstract
Little information exists in humans on the regulation that oxidized low-density lipoprotein (oxLDL) exerts on adipocyte metabolism, which is associated with obesity and type 2 diabetes. The aim was to analyze the oxLDL effects on adipocytokine secretion and scavenger receptors (SRs) and cell death markers in human visceral adipocytes. Human differentiated adipocytes from visceral adipose tissue from non-obese and morbidly obese subjects were incubated with increasing oxLDL concentrations. mRNA expression of SRs, markers of apoptosis and autophagy, secretion of adipocytokines, and glucose uptake were analyzed. In non-obese and in morbidly obese subjects, oxLDL produced a decrease in insulin-induced glucose uptake, a significant dose-dependent increase in tumor necrosis factor-α (TNF-α), IL-6, and adiponectin secretion, and a decrease in leptin secretion. OxLDL produced a significant increase of Lox-1 and a decrease in Cxcl16 and Cl-p1 expression. The expression of Bnip3 (marker of apoptosis, necrosis and autophagy) was significantly increased and Bcl2 (antiapoptotic marker) was decreased. OxLDL could sensitize adipocytes to a lower insulin-induced glucose uptake, a more proinflammatory phenotype, and could modify the gene expression involved in apoptosis, autophagy, necrosis, and mitophagy. OxLDL can upregulate Lox-1, and this could lead to a possible amplification of proinflammatory and proapoptotic effects of oxLDL.

Abstract
BACKGROUND Metabolic syndrome, a risk factor of cardiovascular disease, is more common in patients with psoriasis than in the general population. Circulating adipokine concentrations are altered in patients with psoriasis and are suggested to represent the pathophysiological link between psoriatic lesions and metabolic alterations. OBJECTIVES To perform a systematic review of the literature for studies that investigated possible differences in circulating levels of leptin, adiponectin or resistin in patients with psoriasis before and after any treatment intervention, and to meta-analyse the best evidence available. METHODS A search was conducted in three databases (PubMed, Central and Embase). Eligible for the review were studies that assessed leptin, adiponectin or resistin concentrations in patients with psoriasis before and after any topical or systemic treatment. RESULTS After treatment, blood concentrations of leptin were similar to those before treatment [standardized mean difference (SMD) 0·06, 95% confidence interval (CI) -0·09 to 0·20], with no heterogeneity among studies (I2 = 0%, P = 0·88). After treatment, blood concentrations of adiponectin were similar to those before treatment (SMD -0·14, 95% CI -0·34 to 0·05), with significant heterogeneity among studies (I2 = 36·8%, P = 0·032). After treatment, blood concentrations of resistin were significantly lower than those before treatment (SMD 0·50, 95% CI 0·20-0·79), with significant heterogeneity among studies (I2 = 61·4%, P < 0·001). CONCLUSIONS There is no evidence that treatment for psoriasis modifies leptin and adiponectin concentrations. However, treatment intervention reduces resistin concentrations, a finding that is expected to be of clinical importance.

Abstract
Purpose To evaluate the association of serum levels of adipokines and cytokines with psoriasis. Materials and Methods A comprehensive literature search was performed in PubMed, ScienceDirect and Web of Science for the available relevant studies published before December 1, 2016. Differences in serum marker levels between patients and controls were pooled as standardized mean differences (SMDs) with 95% confidence interval to combine the effect estimations. We also conducted stratified analysis, meta-regression analysis and sensitivity analysis. Results Sixty-three studies containing 2876 psoriasis patients and 2237 healthy controls were included in this meta-analysis. The pooled serum levels of TNF-α, IFN-γ, IL-2, IL-6, IL-8, IL-18, IL-22, chemerin, lipocalin-2, resistin, sE-selectin, fibrinogen and C3 were higher in psoriasis patients compared with healthy controls (all P < 0.05). In contrast, adiponectin levels were lower. Serum levels of IL-1β, IL-4, IL-10, IL-12, IL-17, IL-21, IL-23, visfatin and omentin were not significantly different between psoriasis patients and controls (all P > 0.05). However, increased serum levels of IL-17 correlated with psoriasis in men. For other biomarkers, age, gender and psoriasis area and severity index did not explain the differences in effect size between the studies. Conclusions Serum levels of TNF-α, IFN-γ, IL-2, IL-6, IL-8, IL-18, IL-22, chemerin, lipocalin-2, resistin, sE-selectin, fibrinogen, complement 3, and adiponectin correlate with psoriasis and can be used as potential biomarkers for psoriasis and response to the treatment. Future studies are needed to identify additional players involved in the pathogenesis of psoriasis and to fully decipher the underlying mechanism.

Abstract
Epidemiological studies suggest an increased prevalence of cardiovascular disease (CVD) in patients with psoriasis (PS). Therefore, emphasis has lately been laid on the necessity for clinical evaluation of the risk of CVD in these patients. The systemic inflammatory markers C-reactive protein (CRP) and interleukin- (IL-) 6, which have long been used to predict future CVD in the general population, are increased manyfold in patients with PS. Lipid abnormalities characterized by elevated triglycerides, low HDL cholesterol, and higher concentrations of LDL cholesterol and its oxidized form are also prevalent in patients. There is a need for additional laboratory markers for the assessment of cardiovascular status of patients with PS. Due to frequent comorbid overweight and obesity, biologically active compounds produced by adipocytes may have an impact on monitoring the status of the cardiovascular system of patients with PS. For this purpose, two adipokines, adiponectin and leptin, have been most extensively studied. The review focuses on some inflammatory and oxidative stress aspects in patients with PS through the analysis of the impact of prominent adipokines and oxidized low-density lipoprotein (oxLDL) to assess their eligibility for clinical practice as markers of CVD risk in patients with PS.

Abstract
Leptin is an adipocyte-derived cytokine secreted mostly by adipose tissue. Serum leptin levels are elevated in obese individuals and correlate positively with body mass index (BMI). Interestingly, serum leptin levels are also elevated in patients with psoriasis and correlate positively with disease severity. Psoriasis is associated with obesity; patients with psoriasis have a higher incidence of obesity, and obese individuals have a higher risk of developing psoriasis. Additionally, obese patients with psoriasis experience a more severe degree of psoriasis. In this study, we hypothesised that leptin may link psoriasis and obesity and plays an aggravating role in psoriasis. To investigate leptin's role in psoriasis, we applied the widely accepted imiquimod (IMQ)-induced psoriasis-like skin inflammation mouse model on leptin-deficient (ob/ob) mice and evaluated psoriasis severity. Moreover, we stimulated human keratinocytes with leptin and investigated the effect on proliferation and expression of pro-inflammatory proteins. In ob/ob mice, clinical signs of erythema, infiltration and scales in dorsal skin and inflammation in ear skin, as measured by ear thickness, were attenuated and compared with wt mice. Moreover, IL-17A and IL-22 mRNA expression levels, as well as increased epidermal thickness, were significantly less induced. In vitro, the effect of leptin stimulation on human keratinocytes demonstrated increased proliferation and induced secretion of several pro-inflammatory proteins; two hallmarks of psoriasis. In conclusion, leptin deficiency attenuated IMQ-induced psoriasis-like skin inflammation in a mouse model, and leptin stimulation induced a pro-inflammatory phenotype in human keratinocytes, thus, supporting an aggravating role of leptin in psoriasis.

Abstract
The presented article studies the role of selected inflammatory and anti-inflammatory serum markers of psoriatic patients in the pathogenesis of metabolic syndrome (MS) and psoriasis. The study is based on the comparison between the group of psoriatic patients (74) and the control group (65). We found significantly higher BMI (p < 0.05) and diastolic blood pressure (p < 0.05) in the psoriatic patients. The values of waist circumference and BMI were significantly higher (p < 0.05) in the male patients compared to the men in the control group. The analysis revealed significantly higher CRP (p < 0.001), Lp-PLA2 (p < 0.001), leptin (p < 0.01), and resistin (p < 0.01) levels in the psoriatic patients. Significantly higher levels of CRP (p < 0.01), Lp-PLA2 (p < 0.001), leptin (p < 0.01), and resistin (p < 0.05) were found in the patients with MS compared to the controls with MS. The level of adiponectin was significantly lower (p < 0.01) in the patients with MS. Finally, we found significantly higher level of Lp-PLA2 (p < 0.001) in the group of patients without MS compared to the controls without MS. In conclusion, observed inflammatory and anti-inflammatory markers (CRP, adiponectin, leptin, resistin, and Lp-PLA2) are involved in both pathogenesis of MS and pathogenesis of psoriasis. The level of Lp-PLA2 indicates the presence of subclinical atherosclerosis (cardiovascular risk) in psoriatic patients.

Abstract
T helper 17 (Th17) cells are vital components of the adaptive immune system involved in the pathogenesis of most autoimmune and inflammatory syndromes, and adiponectin(ADN) is correlated with inflammatory diseases such as multiple sclerosis (MS) and type II diabetes. However, the regulatory effects of adiponectin on pathogenic Th17 cell and Th17-mediated autoimmune central nervous system (CNS) inflammation are not fully understood. In this study, we demonstrated that ADN could inhibit Th1 and Th17 but not Th2 cells differentiation in vitro. In the in vivo study, we demonstrated that ADN deficiency promoted CNS inflammation and demyelination and exacerbated experimental autoimmune encephalomyelitis (EAE), an animal model of human MS. Furthermore, ADN deficiency increased the Th1 and Th17 cell cytokines of both the peripheral immune system and CNS in mice suffering from EAE. It is worth mentioning that ADN deficiency predominantly promoted the antigen-specific Th17 cells response in autoimmune encephalomyelitis. In addition, in vitro and in vivo, ADN upregulated sirtuin 1 (SIRT1) and peroxisome proliferator-activated receptor γ (PPARγ) and inhibited retinoid-related orphan receptor-γt (RORγt); the key transcription factor during Th17 cell differentiation. These results systematically uncovered the role and mechanism of adiponectin on pathogenic Th17 cells and suggested that adiponectin could inhibit Th17 cell-mediated autoimmune CNS inflammation.

Abstract
Psoriasis is a chronic inflammatory skin disease, often associated with overweight/obesity. The adipose tissue is a complex organ that secretes several adipokines, involved in the regulation of some metabolic processes, such as lipid metabolism, glucose homeostasis, angiogenesis, blood pressure and inflammation. In obesity, the distribution and function of adipose tissue, and the adipokine profile are altered. The unbalanced production of pro- and anti-inflammatory adipokines in obesity, contributes to the development of a chronic low-grade inflammation state, which seems to favour worsening of psoriasis lesion and a poorer response to treatment. In this review, we will debate published data concerning the current knowledge about the triad psoriasis-obesity-adipokine profile.

Abstract
Accumulating epidemiologic evidence has revealed that metabolic syndrome is an independent risk factor for psoriasis development and is associated with more severe psoriasis. Adiponectin, primarily recognized as a metabolic mediator of insulin sensitivity, has been newly drawing attention as a mediator of immune responses. Here we demonstrate that adiponectin regulates skin inflammation, especially IL-17-related psoriasiform dermatitis. Mice with adiponectin deficiency show severe psoriasiform skin inflammation with enhanced infiltration of IL-17-producing dermal Vγ4+γδ-T cells. Adiponectin directly acts on murine dermal γδ-T cells to suppress IL-17 synthesis via AdipoR1. We furthermore demonstrate here that the adiponectin level of skin tissue as well as subcutaneous fat is decreased in psoriasis patients. IL-17 production from human CD4- or CD8-positive T cells is also suppressed by adiponectin. Our data provide a regulatory role of adiponectin in skin inflammation, which would imply a mechanism underlying the relationship between psoriasis and metabolic disorders.

Abstract
INTRODUCTION Psoriasis is an inflammatory and chronic skin disease associated with obesity, cardiovascular diseases, diabetes and metabolic syndrome. Adipokines, as bioactive substances secreted from adipose tissue, are involved in various metabolic diseases. AIM To investigate the association between psoriasis severity and serum adiponectin and leptin levels in patients with psoriasis. MATERIAL AND METHODS Serum fasting adiponectin and leptin levels were examined by an enzyme-linked immunosorbent assay in 49 patients with relapse of plaque-type psoriasis and 16 healthy controls. The results were correlated with the Psoriasis Area and Severity Index (PASI), body mass index (BMI), several inflammatory markers, duration of the disease and present relapse. RESULTS Serum adiponectin and leptin levels were significantly decreased in psoriatic patients in comparison to the control group. There were no correlations between the above measures and PASI scores, patients' age, duration of the disease, present relapse and hospitalization, neither between white blood cells or platelets counts. Serum adiponectin levels significantly correlated with C-reactive protein (CRP) levels. Adiponectin was negatively and leptin positively correlated to BMI at statistical significance. Multivariate analysis demonstrated a significant positive correlation between adiponectin and CRP or PASI concentrations as well as between BMI and leptin concentration. CONCLUSIONS The data showed that serum adiponectin levels increase and serum leptin levels decrease with psoriasis severity. Leptin might be useful in assessing severity and the risk of complications of psoriasis. Moreover, these results confirmed the relationship between leptin, obesity and psoriasis.

Abstract
OBJECTIVES Psoriasis has been considered as a systemic disease associated with obesity, cardiovascular diseases and metabolic syndrome. Adipokines have influence on many metabolic processes. Aim of this study was to evaluate the effect of conventional topical treatment on serum adiponectin and leptin levels in patients with psoriasis. METHODS Forty-nine patients with relapse of plaque-type psoriasis and 16 healthy controls were examined. Blood samples were collected before therapy and after 14 days of application. Serum adiponectin and leptin concentrations were examined by enzyme-linked immunosorbent assay for correlations with effectiveness of topical treatment. RESULTS Adiponectin and leptin serum levels were significantly decreased in psoriatic patients in comparison to the controls. As a result of the topical treatment, serum adiponectin level did not significantly change. Serum leptin level increased significantly, still remaining lower than in the controls. CONCLUSIONS Leptin might be a useful marker in assessing the efficacy of the treatment for psoriasis.

Abstract
Psoriasis is a disorder caused by genetic and immunological factors. Leptin, a peptide hormone secreted predominantly from adipose tissue, regulates energy intake and expenditure, as well as the T-helper response. There have been conflicting reports regarding serum levels of leptin and adiponectin in patients with psoriasis. In the present study, we measured serum levels of leptin and adiponectin in Korean patients with psoriasis. Twenty-four patients with psoriasis and fifteen control subjects were included in the study. Serum leptin and adiponectin levels were determined by an immunometric sandwich enzyme-linked immunosorbent assay (ELISA). The mean serum leptin concentration in patients with psoriasis was higher than in controls, and the difference was statistically significant. In contrast, serum adiponectin levels in patients with psoriasis were significantly decreased compared with healthy controls. Leptin levels in vitamin D-deficient patients were statistically significantly higher than in vitamin D-sufficient patients. Serum adiponectin concentrations showed a negative correlation with body mass index (BMI) and psoriasis area and severity index (PASI) in patients with psoriasis. In conclusion, the present study demonstrated that leptin and adiponectin may play a role in the immunopathogenesis of psoriasis and may be useful biomarkers indicating severity of psoriasis in Korean patients.

Abstract
Psoriasis is a lifelong disorder characterized by approximately 8-fold reduction of the duration of normal skin keratinocyte cell cycle and 2-fold increase of the number of dividing cells. Multiple genes, several environmental factors, and immune system alterations are involved in the pathogenesis of psoriasis. Hyperleptinemia is associated with psoriasis and leptin acts as an angiogenic factor. Angiogenetic processes precede the epidermal hyperplasia in psoriasis, indicating possible involvement of leptin in the pathogenesis of psoriasis. Leptin gene polymorphisms and their association with psoriasis have been given very little attention. We present a study of the rs2060713C/T genetic polymorphism in the pathogenesis of psoriasis vulgaris in 263 vulgaris patients and 252 unrelated matched healthy controls. No statistically significant differences were observed between patients and controls. A statistically nonsignificant trend was observed in males with the early onset type of psoriasis (11.1% C/T in patients versus 5.6% in controls) and in females with the late onset type of the disease (12.8% C/T in patients versus 3.3% in controls). Still, there is no hard evidence on correlation of psoriasis vulgaris with this polymorphism. Possible association with specific forms of the disease and either gender needs further investigation in larger studies.

Abstract
OBJECTIVES To assess clinical and laboratory parameters associated with metabolic syndrome in Turkish patients with moderate or severe plaque-type psoriasis and nonpsoriatic controls. METHODS Patients with moderate or severe plaque psoriasis (patient group) or with nonpsoriatic dermatological disease (controls) were included. Waist circumference, weight, height and arterial blood pressure were measured, together with fasting blood glucose, triglyceride, high density lipoprotein (HDL), fibrinogen, homocysteine and adiponectin levels. Metabolic syndrome was diagnosed using National Cholesterol Education Program-Adult Treatment Panel III criteria. RESULTS Out of 90 patients (50 with psoriasis; 40 controls), metabolic syndrome was more frequent in the patient group than in controls. In terms of metabolic syndrome parameters, only hypertension was more frequent in patients with psoriasis compared with controls. There was no statistically significant difference between the patient and control groups for obesity, hypertriglyceridaemia, HDL levels or hyperglycaemia. Fibrinogen levels were increased and adiponectin levels were decreased in the psoriasis group. No between-group difference in homocysteine levels was found. CONCLUSION In this small study, metabolic syndrome was found to be more frequently identified in Turkish patients with psoriasis than in controls; metabolic syndrome could lead to increased cardiovascular disease risk in patients with moderate to severe psoriasis.

Abstract
OBJECTIVE To assess cardiometabolic biomarkers in patients with psoriasis before and after etanercept treatment. METHODS Patients with moderate-to-severe plaque psoriasis were randomized to etanercept 50 mg once or twice weekly, double-blinded. Cardiometabolic biomarkers were assessed at baseline and after 12 weeks of treatment (n = 273). RESULTS At baseline, 42% of patients had metabolic syndrome. Etanercept was not associated with any clinically relevant adverse effects on cardiometabolic biomarkers. In the once-weekly subgroup, significant mean percentage changes from baseline (p < 0.05) were observed for the quantitative insulin-sensitivity check index (QUICKI; -2.2%), apolipoprotein (Apo) A1 (3.2%), Apo B:Apo A1 ratio (-3.5%), leptin (8.6%) and high-sensitivity C-reactive protein (hsCRP) (-65.5%); and in the twice-weekly subgroup for plasma insulin (15.9%), QUICKI (-2.7%), high-density lipoprotein cholesterol (HDL-C; 2.9%), apolipoprotein (Apo) A1 (2.8%), Apo B:Apo A1 (-4.6%) and hsCRP (-74.4%). CONCLUSION Metabolic syndrome was common in these patients with moderate-to-severe psoriasis. Etanercept treatment may provide some potentially favorable modulation of insulin sensitivity, HDL-C, Apo A1 and Apo B:Apo A1 ratio.

Abstract
BACKGROUND There have been inconsistent results reported for leptin levels in patients with psoriasis. AIM To evaluate leptin levels in patients with psoriasis using a meta-analysis of studies comparing leptin levels in controls and in patients with psoriasis. METHODS PubMed (MEDLINE), EMBASE and the Cochrane Library were searched for relevant papers published in English. Pooled weighted mean differences (WMDs) and 95% CIs were calculated using random-effects and fixed-effects models. Heterogeneity between studies was assessed using the Cochran Q and I(2) statistics. RESULTS In total, 11 studies, comprising 773 patients with psoriasis and 570 healthy controls, were identified. Leptin levels were significantly higher in patients with psoriasis compared with controls (WMD = 7.24, 95% CI 4.55-9.93; P < 0.001). On stratified analysis, significant differences in leptin levels between patients with psoriasis and controls were reported only in serum samples (P < 0.001), and not in plasma samples (P = 0.025). Sensitivity analysis showed that there were no changes in the direction of effect when any one study was excluded. No publication bias was detected. CONCLUSIONS Leptin levels are higher in patients with psoriasis compared with those in controls. Future studies are warranted to clarify the association between leptin levels and the pathomechanism of psoriasis.

Abstract
Conflicting results regarding adiponectin levels in patients with psoriasis have been reported. We carried out a meta-analysis on studies which compared adiponectin levels of psoriatic patients with controls. A published work search was performed through PubMed (MEDLINE), EMBASE and the Cochrane Library for articles published in English. Pooled standardized mean difference (SMD) and 95% confidence intervals (95% CI) were calculated by using random effects and fixed effect models. Heterogeneity between studies was assessed using the Cochran's Q and I(2) statistics. A total of nine studies were enrolled (389 cases and 360 controls) for adiponectin, and three studies were included (132 cases and 132 controls) for high-molecular weight (HMW) adiponectin. Adiponectin and HMW adiponectin levels were not significantly different in patients with psoriasis compared with controls (SMD, -0.151 [95% CI, -0.616 to 0.315]; P = 0.526 for adiponectin; SMD, 0.999 [95% CI, -2.626 to 4.624]; P = 0.589 for HMW adiponectin). The associations were borderline significantly different in the stratum of those with a mean age of less than 40 years (SMD, -0.516 [95% CI: -1.032 to 0]; P = 0.050). Sensitivity analyses were not substantially altered in the direction of effect when any one study was excluded. No publication bias was detected. The level of adiponectin and HMW adiponectin may not be associated with psoriasis. The relationship between psoriasis and adipokines needs more in-depth studies with larger sample sizes.

Abstract
Psoriasis has been related to metabolic syndrome (MS). Adipocytokines produced by white adipose tissue may be involved in the pathogenesis of psoriasis and its association with MS. Our objectives were to characterize the profile of a number of different inflammatory and atherogenic markers, vitamins, adipokines and cytokines and their potential involvement in MS in patients with moderate-to-severe psoriasis without joint involvement compared to anthropometrically matched controls, and to evaluate correlation with severity of the skin disease and changes after narrow-band UVB (NB-UVB) phototherapy. We designed a prospective cross-sectional study. Baseline waist circumference, body fat composition, lipid, carbohydrate and calcium metabolism profile, inflammation markers, homocysteine and vitamins D, B6, B12 and folic acid, leptin, resistin, omentin, lipocalin-2, adipocyte fatty acid-binding protein, retinol-binding protein-4 (RBP-4), interleukin-6, soluble tumour necrosis factor receptor 1 (sTNFR1) and interleukin-17 of 50 psoriasis patients and 50 gender, age and body mass index-matched controls were recorded, then evaluated after NB-UVB in the patients. The patients had higher baseline serum concentrations of leptin, RBP-4, lipocalin-2 and sTNFR1. Baseline psoriasis area and severity index correlated with serum concentrations of RBP-4 and lipocalin-2 only. Principal components analysis disclosed a component including vitamins B12, B6, folic acid, calcidiol and HDL-cholesterol that was only present in healthy controls and opposed to a cluster of variables which promote MS. This component was absent in the patients. Our results point to lipocalin-2 and RBP-4 as relevant mediators of the trend towards MS in psoriatic patients.

Abstract
BACKGROUND Psoriasis vulgaris (PV) is associated with low-grade systemic inflammation. OBJECTIVE Cytokines' and growth factors' serum patterns in patients with PV, allergic contact dermatitis (ACD) and healthy subjects were investigated to describe and compare systemic inflammatory responses in these diseases. METHODS A total of 12 inflammation-sensitive biomarkers were analyzed simultaneously by means of the Evidence Investigator™ biochip technology. RESULTS In PV, proinflammatory tumor necrosis factor (TNF)-α, interferon (IFN)-γ, interleukins (IL)-1β, -2, -6, -8, and monocyte chemoattractant protein (MCP)-1 were elevated. In ACD, 2 markers, TNF-α and MCP-1, were increased, and regulatory cytokine IL-10 was decreased. Proinflammatory IL-2 had the strongest correlations with other pro- as well as anti-inflammatory cytokines in PV and ACD, whilst IL-6 correlated positively with the Psoriasis Area and Severity Index. Growth factors' levels correlated with MCP-1, but only in PV. CONCLUSION Although psoriasis induces a more variegated proinflammatory systemic response, ACD is likewise associated with a systemic increase in inflammatory mediators.

Abstract
Psoriatic arthritis (PsA) is an inflammatory arthritis associated with psoriasis. In addition to skin and joint involvement, there is increasing evidence suggesting that patients with PsA also have an increase in risk of clinical and subclinical cardiovascular diseases, mostly due to accelerating atherosclerosis. Both conventional and nonconventional cardiovascular risk factors contribute to the increased cardiovascular risk in PsA. Chronic inflammation plays a pivotal role in the pathogenesis of atherosclerosis in PsA, acting independently and/or synergistically with the conventional risk factors. In this paper, we discuss the current literature indicating that patients with PsA are at risk of cardiovascular diseases.

Abstract
BACKGROUND Psoriasis is a chronic, inflammatory skin disease associated with abnormal plasma lipid metabolism and with a high frequency of cardiovascular events. Modifications of plasma lipids and an increase in the levels of biochemical markers of lipid peroxidation have been reported in subjects with psoriasis, suggesting a relationship between psoriasis, lipoproteins and oxidative damage. OBJECTIVES To investigate further the relationship between lipoproteins and oxidative stress in psoriasis. METHOD The levels of plasma lipids, lipoprotein(a) [Lp(a)] and markers of lipid peroxidation were evaluated in subjects with psoriasis (n=23) and in controls (n=25). In the same subjects, the activity of paraoxonase-1 (PON1), an antioxidant and an anti-inflammatory enzyme associated with high-density lipoproteins, was investigated. RESULTS The results showed higher levels of Lp(a) in the serum of patients with psoriasis compared with controls (P<0·001). Higher levels of lipid hydroperoxides (P<0·001) and lower PON1 activity were observed in the serum of patients compared with healthy subjects, confirming that psoriasis is associated with oxidative stress. The imbalance between oxidative stress and antioxidant enzymes, and the increase of Lp(a) serum levels was related to the extent and severity of psoriasis. Finally, our results demonstrated that Lp(a) levels were positively correlated with markers of lipid peroxidation and negatively related to PON1 activity, suggesting that subjects with higher levels of Lp(a) are more exposed to oxidative damage. CONCLUSIONS Our results provide further evidence that oxidative stress and impairment of the antioxidant system in the plasma of patients may play a role in pathogenesis and progression of psoriasis and related complications.

Abstract
Psoriasis is a common, chronic inflammatory skin disease that can cause significant discomfort and impairment to quality of life. Recent research indicates that individuals with moderate-to-severe psoriasis are likely at greater risk for chronic cardiometabolic co-morbidities such as cardiovascular disease, type 2 diabetes, obesity and metabolic syndrome. Physical activity can be an effective primary and adjunctive treatment for these maladies in other populations. Unfortunately, only a limited number of studies have examined physical activity in psoriasis, which are limited by poor design and lack of validated physical activity assessment methodologies. A variety of data suggest shared physiologic pathways between physical activity, psoriasis, and psoriasis cardiometabolic co-morbidities. Increased adiposity, inflammation, oxidative stress, adhesion molecules and lipids are physiologically linked to psoriasis, the risk of psoriasis cardiometabolic co-morbidities, and low levels of physical activity. In addition, epigenetic pathways are involved in psoriasis and could be influenced by physical activity. The physical and psychosocial impairments common in psoriasis may make it difficult to participate in regular physical activity, and future studies should aim to determine if physical activity interventions improve functioning and reduce co-morbidities in psoriasis.

Abstract
The atherosclerotic process is accelerated in several autoimmune rheumatic diseases. Effector cells of innate and adaptive immunity along with pro-inflammatory cytokines and other immune mediators are found in atherosclerotic lesions, where they play an important role in induction, progression and rupture of plaques. Psoriatic arthritis (PsA) is a chronic inflammatory disease, characterized by arthritis, enthesitis, dactilytis, osteitis, and axial involvement, along with skin manifestations. PsA is frequently associated with obesity, diabetes, dyslipidemia, hypertension, accelerated atherosclerosis and with increased cardiovascular morbidity and mortality. Disease-specific and traditional risk factors seem to account for the atherosclerotic burden in PsA patients. Some immunological factors which are involved in PsA can also contribute to atherosclerosis including C reactive protein (CRP), TNF-α, IFN-γ, IL-1, Il 6, IL23, and Th17.
