Kimak A, Woźniacka A. The Role of Osteopontin in Psoriasis-A Scoping Review. J Clin Med 2024; 13:655. [PMID: 38337350 PMCID: PMC10856165 DOI: 10.3390/jcm13030655] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2023] [Revised: 01/03/2024] [Accepted: 01/18/2024] [Indexed: 02/12/2024] Open
Abstract
Psoriasis is a chronic systemic disease with an immunological basis and a complex pathophysiology. The chronic inflammatory status of psoriasis is associated with several comorbidities, such as metabolic syndrome, obesity, and cardiovascular disease. The development of psoriasis is influenced by osteopontin, a glycoprotein that influences physiological and pathological reactions by modulating Th1 and Th17 cellular responses, stimulating keratinocyte proliferation, regulating cellular apoptosis, and promoting angiogenesis. The recent identification of immune pathways involved in psoriasis development has facilitated the development of biological treatments; however, a better understanding of the intricate relationship between underlying inflammatory processes, psoriasis development, and accompanying comorbidities is needed for improved disease management.

Osteopontin and Regulatory T Cells in Effector Phase of Allergic Contact Dermatitis. J Clin Med 2023; 12:jcm12041397. [PMID: 36835932 PMCID: PMC9962476 DOI: 10.3390/jcm12041397] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2022] [Revised: 01/07/2023] [Accepted: 02/06/2023] [Indexed: 02/12/2023] Open
Abstract
Studies have shown that osteopontin (OPN) and regulatory T cells play a role in allergic contact dermatitis (ACD), but the mechanisms responsible for their function are poorly understood. The study aimed to determine CD4 T lymphocytes producing intracellular osteopontin (iOPN T cells) and assess the selected T lymphocyte subsets including regulatory T cells in the blood of patients with ACD. Twenty-six patients with a disseminated form of allergic contact dermatitis and 21 healthy controls were enrolled in the study. Blood samples were taken twice: in the acute phase of the disease and during remission. The samples were analyzed by the flow cytometry method. Patients with acute ACD showed significantly higher percentage of iOPN T cells compared with healthy controls which persisted during remission. An increase in the percentage of CD4CD25 and a reduced percentage of regulatory T lymphocytes (CD4CD25highCD127low) were also found in the patients with acute stage of ACD. The percentage of CD4CD25 T lymphocytes showed a positive correlation with the EASI index. The increase in the iOPN T cells can indicate their participation in acute ACD. The decreased percentage of regulatory T lymphocytes in the acute stage of ACD may be related to the transformation of Tregs into CD4CD25 T cells. It may also indicate their increased recruitment to the skin. The positive correlation between the percentage of CD4CD25 lymphocytes and the EASI index may be indirect evidence for the importance of activated lymphocytes-CD4CD25 in addition to CD8 lymphocytes as effector cells in ACD.

Abstract
Background and Objectives: Trifarotene is a topical retinoid selective for retinoic acid receptor gamma that was recently approved for treatment of acne vulgaris. We performed a gene expression analysis to identify the molecular and cellular impact of trifarotene treatment on acne papules. Methods: In this open-label prospective study, subjects with moderate inflammatory acne of the back were treated with trifarotene 0.005% or vehicle cream on dedicated areas for 27 days, and 4 biopsies were collected from each subject (1 from skin without a visible acne lesion and three at the site of an acne papule: one baseline, one after vehicle treatment, and one after trifarotene treatment). Large scale gene expression profiling of the biopsies was performed using Affymetrix technology, treatment-specific gene expression profiles were generated using statistical modeling, and pathway analysis was performed. Using single-cell RNAseq data, in silico deconvolution of transcriptomics data was performed to identify cellular signatures. Results: We discovered a unique set of 67 genes modulated by trifarotene that are primarily involved in cellular migration, inflammation, and extracellular matrix reorganization. Changes in cellular expression were similar in both trifarotene-treated and spontaneously-resolving lesions. However, only trifarotene treatment impacted SPP1+ macrophages, a subset of highly proliferative macrophages recently identified in fibrotic tissue. Conclusions: These results show that trifarotene has a novel action in acne treatment by affecting epidermal and immune components of acne pathogenesis.

Abstract
Purpose Atopic dermatitis (AD) is a chronic, relapsing inflammatory disease, caused by environmental and genetic factors, which lead to immunological abnormalities. Osteopontin (OPN), also named secreted phosphoprotein 1 (SPP1), is a protein involved in the pathogenesis of numerous autoimmune and inflammatory conditions. However, its role in AD has not been fully elucidated. Therefore, we aim to gain an insight into the role of OPN in AD pathogenesis through investigating its gene single nucleotide polymorphisms (SNPs) and their possible associations with disease clinical features. Patients and Methods A total of 182 Caucasian participants (45 AD patients and 137 gender- and age-matched controls) were studied. Genomic DNA was isolated from peripheral blood samples. Genotyping for the rs1126616 C>T, rs1126772 A>G, rs9138 A>C, and rs3841116 T>G SNPs was performed by real time polymerase chain reaction (RT-PCR). Results The frequency of the minor TT genotype and the T allele of rs1126616 C>T was higher in AD patients compared to controls (P = 0.019, OD = 4.86, 95% CI = 1.46–16.20, and P = 0.047, OR = 1.77, 95% CI = 1.04–3.00, respectively) and was associated with the higher prevalence of asthma (P = 0.017, OR = 3.73, 95% CI = 0.71–19.67, and P = 0.004, OR = 3.96, 95% CI = 1.53–10.25, respectively). Likewise, the minor GG genotype and the G allele of rs1126772 A>G were more frequent in AD patients (P = 0.026, OR = 3.27, 95% CI = 1.29–8.33, and P = 0.013, OR = 1.94, 95% CI = 1.18–3.21, respectively) and were associated with the increased incidence of asthma (P = 0.016, OR = 5.06, 95% CI = 1.14–22.49, and P = 0.002, OR = 4.40, 95% CI = 1.71–11.35, respectively). Furthermore, haplotype frequency estimation determined the four-loci haplotype TGCT, as a significant risk factor for AD compared to controls (P = 0.031, OR = 9.48, 95% CI = 1.23–71.91). Conclusion Our results suggest that the variation in the OPN gene might be associated with AD and increased incidence of asthma in Caucasians. Further studies should be conducted to look into the possible role of OPN as a biomarker for AD.

Cardiomyopathy and echocardiographic abnormalities in Indian patients with psoriasis: Results of a pilot study. Int J Clin Pract 2021; 75:e13756. [PMID: 33064900 DOI: 10.1111/ijcp.13756] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/04/2020] [Accepted: 10/04/2020] [Indexed: 01/19/2023] Open
Abstract
BACKGROUND The relationship between psoriasis and cardiomyopathy is understudied in Indian patients. OBJECTIVE We evaluated psoriasis patients for cardiomyopathy and other echocardiographic abnormalities. METHODS About 98 (M:F = 67:31) patients with mild to moderate psoriasis aged 18-75 years (mean ± SD = 42.12 ± 12.79 years) having no pre-existing metabolic syndrome and cardiovascular disorders were studied. X-ray chest, electrocardiogram and echocardiography were performed and interpreted by cardiologist for size of the left and right ventricles, left ventricle ejection fraction, diastolic function, pulmonary artery pressure and valve abnormality/regurgitation and their severity as per current guidelines/recommendations. The cardiomyopathies were defined according to standard diagnostic guidelines. RESULTS Echocardiographic abnormalities were noted in 13 (13.3%) patients aged 19-75 years (mean ± SD = 43.30 ± 15.71 years). The left ventricular diastolic dysfunction (grade 1) was observed in nine patients (moderate severe psoriasis in four patients) and one of them also had concentric left ventricular hypertrophy; a precursor of restrictive cardiomyopathy. Mild tricuspid valve regurgitation was present in other four patients. There was no statistically significant difference in age, gender, duration and the severity of psoriasis when compared with patients having normal echocardiography. The mitral or aortic valves, pulmonary artery pressure, mid-right-ventricular diameter and the left atrial volume showed no abnormality. CONCLUSIONS Psoriasis perhaps plays a role in left ventricular dysfunction and possibly cardiomyopathy even with moderately severe disease and in the absence of clinical symptoms. However, these observations need to be interpreted with caution in the absence of any statistically significant difference between age, gender, duration and severity of psoriasis in the patients having normal and abnormal echocardiography.

Abstract
Psoriasis (Ps) is an immune-mediated inflammatory skin disease that is widely associated with the clinical features of metabolic syndrome (MetS), including hypertension, abdominal obesity, insulin resistance, type 2 diabetes and dyslipidemia. Osteopontin (OPN), a multifunctional protein involved in the modulation of inflammatory processes, may contribute to the development of atherosclerosis and MetS. Therefore, the aim of the study was the assessment of the correlation between OPN concentration in the peripheral blood and the presence of MetS as well as its particular components in the Ps patients. The study comprised 107 male Ps patients (50 patients with MetS and 57 without MetS) and 38 healthy volunteers (HVs). The concentration of OPN in serum was determined using enzyme-linked immunosorbent assay (ELISA) method. Fasting blood glucose and lipid profile components: total cholesterol (total CHOL), high-density lipoprotein cholesterol (HDL-CHOL), low-density lipoprotein cholesterol (LDL-CHOL), triglycerides (TG) were examined. Ps patients with MetS had significantly higher obesity, systolic blood pressure, TG, CHOL/HDL, LDL/HDL and TG/HDL ratios than Ps patients without MetS. OPN serum concentration was significantly higher in the Ps patients than in the HVs (p = 0.022) but not significantly different between the Ps patients with and without MetS (p = 0.275). OPN serum concentration in Ps patients correlated negatively with total CHOL (p = 0.004) and TG (p = 0.009). OPN is increased in Ps patients and may serve as a biomarker of some lipid abnormalities in them.

The Association of Metabolic Syndrome and Psoriasis: A Systematic Review and Meta-Analysis of Observational Study. Endocr Metab Immune Disord Drug Targets 2020; 20:703-717. [DOI: 10.2174/1871530319666191008170409] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/07/2019] [Revised: 09/14/2019] [Accepted: 09/16/2019] [Indexed: 02/06/2023]
Abstract
Background:
Metabolic syndrome worsens complications in psoriasis patients by predisposing
them to cardiovascular diseases. Psoriasis has been widely associated with metabolic syndrome;
however, it has still not been proven owing to a limited number of studies and some of those reporting
conflicting results.
Objective:
Psoriasis has reportedly been associated with metabolic syndrome; however, it has yet not
been established beyond doubt owing to conflicting literature. The present meta-analysis of observational
studies aims to evaluate the prevalence of metabolic syndrome in psoriasis patients and establish
an inferring point that psoriasis patients are certainly susceptible to metabolic syndrome. The study
will benefit clinicians to assess and monitor psoriasis patients for several associated comorbid conditions
and in its treatment.
Methods:
A systematic web search for ‘Psoriasis’, ‘Metabolic Syndrome’, ‘Hypertension’, ‘Plasma
Glucose’, ‘Dyslipidaemia’, ‘Waist Circumference’ was performed, collecting all original observational
studies on humans up to April 30, 2018. Depending on the inclusion and exclusion criteria, articles
were screened for eligibility. Due to the presence of significant heterogeneity, the Odds Ratio (OR)
was calculated using a random-effect model with Der-Simonian and Laird method. The statistical heterogeneity
was determined using I2 statistics. Comprehensive Meta-Analysis Software, Version 3 was
used to perform all the analysis.
Results:
Sixty-three studies encompassing 15,939 psoriasis patients and 103,984 controls were included
in this meta-analysis. Among them, 30.29 % of psoriasis patients were reported with metabolic
syndrome in comparison to 21.70 % of subjects in the control group. The present study clearly indicates
an increased prevalence of metabolic syndrome among psoriasis patients (OR: 2.077 [95% CI,
1.84 - 2.34]).
Conclusions:
The findings support the fact that psoriasis patients have a higher incidence of metabolic
syndrome. Our study also recommends that psoriasis patients should be regularly monitored for metabolic
syndrome complications and its associated risk factors such as hypertension, raised triglyceride,
lowered HDL Cholesterol, increased fasting plasma glucose, and waist circumference.

Abstract
BACKGROUND Several studies have shown a relationship between psoriasis and hypertension, but no meta-analysis has been restricted to studies that adjusted for confounders. The aim of the study was to estimate the association between psoriasis and hypertension with adjustment for covariates. METHODS A systematic literature search in the MEDLINE, Embase, Cochrane databases, and Google Scholar was conducted to identify relevant studies which reported the association of psoriasis with the risk of hypertension published up to November 2018 in English. Data analysis was performed with Stata V.12, and Begg adjusted rank correlation test and Egger regression asymmetry test were used to detect publication bias. RESULTS A total of 16 adjusted-for-covariates studies, involving 50,291 cases with hypertension in 255,132 psoriasis patients and 76,547 cases with hypertension in 814,631 controls (no psoriasis), were included in this meta-analysis. The results indicated that psoriasis was associated with an increased risk of hypertension compared to those without psoriasis, and the prevalence of hypertension in severe psoriasis patients was higher than that in mild psoriasis patients, and the risk of hypertension in psoriasis patients was higher than that in nonpsoriasis patients in Europe and Asia. CONCLUSION We conducted this meta-analysis using the adjusted-for-covariates odds ratio, demonstrating that psoriasis was associated with an increased risk of hypertension compared to those without psoriasis.

Abstract
The aim of this study was to conduct a more comprehensive analysis of the association between psoriasis and abnormal lipid metabolism.The case-control study included 222 psoriatic patients and 445 non-psoriatic control patients matched for age and gender. Clinical parameters included age, gender, and body mass index (BMI). Serum lipid levels were recorded and included cholesterol (CHO), triglycerides (TG), low-density lipoprotein (LDL), high density lipoprotein (HDL), phospholipids (PLIP), free fatty acids (FFA), lipoprotein (a) [Lp(a)], and apolipoproteins (apoA1, apoB, and apoE). Statistical analysis was carried out through the IBM Statistical Package for the Social Studies version 23.0.Compared with controls, levels of BMI and the prevalence of obesity were significantly higher in psoriatic patients. The results revealed that when compared to controls, significant elevation of serum TG (P <.001) and Lp(a) (P = .022) was observed. Levels of HDL (P <.001) and apoA1 (P <.001) were significantly lower in psoriatic patients. There was no significant difference in CHO (P = .367), LDL (P = .400), apoB (P = .294), apoE (P = .05), PLIP (P = .931) and FFA (P = .554) between patients and controls. The levels of CHO, TG, PLIP, FFA, and apoE were positively correlated with BMI level.Dyslipidemia was more common in psoriatic patients, compared with non-psoriatic controls.

Abstract
Osteopontin (OPN) is a pleiotropic cytokine produced both by immune and non-immune cells and active on different cellular targets. OPN production has been associated with several pathological conditions, including autoimmune diseases (e.g. lupus, multiple sclerosis and rheumatoid arthritis) and cancer. Emerging evidence suggests that the role of OPN has been underestimated, as it seems to be working at multiple levels of immune regulation, such as the shaping of T cell effector responses, the regulation of the tumor microenvironment, and the functional interaction with mesenchymal stromal cells. In this context, dendritic cells (DCs) play a crucial role being both an important source and a cellular target for OPN action. DC family is composed by several cell subsets endowed with specific immune functions. OPN exerts its biological functions through multiple receptors and is produced in different intracellular and secreted forms. OPN production by DC subsets is emerging as a crucial mechanism of regulation in normal and pathological conditions and starts to be exploited as a therapeutic target. This review will focus on the role of DC-derived OPN in shaping immune response and on the complex role of this cytokines in the regulation in immune response.

Abstract
BACKGROUND Ultrasound evaluation of carotid intima-media thickness (cIMT) has been extensively used for potentially improving cardiovascular (CV) risk stratification in several patients' categories. Subjects with systemic lupus erythematosus (SLE) have been investigated by both imaging and molecular biomarker approaches with contrasting results. Here, we focused on the role of osteopontin (OPN) as biomarker of subclinical atherosclerosis associated with SLE. MATERIALS AND METHODS Eighty females (age 18-65 years) affected by SLE and eighty age-matched healthy female controls without a clinical history of CV disease underwent ultrasound evaluation of cIMT and blood sample assay of high-sensitivity C-reactive protein (hs-CRP) and OPN. RESULTS Healthy controls and SLE patients significantly differed for CV risk factors (ie, waist circumference, hypertension and dyslipidaemia) and the inflammatory status. Noteworthy, an opposite association between cIMT and OPN was observed in the two study groups. Whereas OPN was positively associated with mean cIMT (r = 0.364; P = 0.001) in SLE patients, a negative correlation was found in healthy controls. Furthermore, in SLE patients increased circulating levels of OPN were associated with the use of hydroxychloroquine and the positivity for the anti-dsDNA autoantibodies. At linear regression analysis, only OPN remained independently associated with cIMT also after adjustment for age, smoking pack-year, Heart SCORE, disease length and steroid therapy length. CONCLUSIONS These results indicate that serum OPN levels were strongly associated with subclinical atherosclerosis in patients with LES and it might be a useful CV biomarker that requires additional validation in larger trials.

Abstract
Multiple sclerosis (MS) is a chronic neurodegenerative autoimmune disease with a complex clinical course characterized by inflammation, demyelination, and axonal degeneration. Diagnosis of MS most commonly includes finding lesions in at least two separate areas of the central nervous system (CNS), including the brain, spinal cord, and optic nerves. In recent years, there has been a remarkable increase in the number of available treatments for MS. An optimal treatment is usually based on a personalized approach determined by an individual patient's prognosis and treatment risks. Biomarkers that can predict disability progression, monitor ongoing disease activity, and assess treatment response are integral in making important decisions regarding MS treatment. This review describes MS biomarkers that are currently being used in clinical practice; it also reviews and consolidates published findings from clinically relevant potential MS biomarkers in recent years. The work also discusses the challenges of validating and application of biomarkers in MS clinical practice.

Abstract
BACKGROUND Psoriasis has been shown to be associated with cardiovascular disease in adults. Little is known about cardiovascular risk in pediatric psoriasis. OBJECTIVE To determine if there is an association between pediatric psoriasis and cardiovascular comorbidities. METHODS Data were analyzed from the 2002-2012 Nationwide Inpatient Sample, which included 4,884,448 hospitalized children aged 0-17 years. Bivariate and multivariate survey logistic regression models were created to calculate the odds of psoriasis on cardiovascular comorbidities. RESULTS In multivariate survey logistic regression models adjusting for age, sex, and race/ethnicity, pediatric psoriasis was significantly associated with 5 of 10 cardiovascular comorbidities (adjusted odds ratio [95% confidence interval]), including obesity (3.15 [2.46-4.05]), hypertension (2.63 [1.93-3.59]), diabetes (2.90 [1.90-4.42]), arrhythmia (1.39 [1.02-1.88]), and valvular heart disease (1.90 [1.07-3.37]). The highest odds of cardiovascular risk factors occurred in blacks and Hispanics and children ages 0-9 years, but there were no sex differences. LIMITATIONS The study was limited to hospitalized children. We were unable to assess the impact of psoriasis treatment or family history on cardiovascular risk. CONCLUSION Pediatric psoriasis is associated with higher odds of multiple cardiovascular comorbidities among hospitalized patients. Strategies for mitigating excess cardiovascular risk in pediatric psoriasis need to be determined.

Abstract
The relationship between psoriasis and metabolic syndrome is not well understood. Though multiple epidemiologic studies have suggested a link between psoriasis and metabolic syndrome, there is a lack of a comprehensive meta-analysis synthesizing the results of all available observational studies to date. In this meta-analysis, we examined global data on the relationship between psoriasis and odds of metabolic syndrome by searching for studies published between 1946–2016. Specifically, we analyzed the results from 35 observational studies from 20 countries with 1,450,188 total participants, of which 46,714 were psoriasis patients. The pooled odds ratio based on random effects analysis was 2.14 (95% CI 1.84–2.48). Publication bias was present, as evidenced by an Egger test and graphical visualization through a funnel plot (p = 0.001). Based on this comprehensive meta-analysis, psoriasis patients have higher odds of having metabolic syndrome when compared with the general population.

Abstract
INTRODUCTION Psoriasis is a chronic inflammatory disease of the skin associated with increased cardiovascular morbidity. Metabolic syndrome is a significant forecaster of cardiovascular events. AIM To assess the association of metabolic syndrome and its components in patients with psoriasis and to compare it with the age and sex matched control group. MATERIALS AND METHODS We conducted a hospital based case-control study on 156 adult patients with chronic plaque psoriasis and 156 patients with skin diseases other than psoriasis. Height, weight, BMI, blood pressure and waist circumference were documented in all the subjects. Fasting levels of serum glucose, serum triglycerides and serum HDL were estimated by automated clinical chemistry analyzer. The South Asian modified NCEP ATP criterion was used for the diagnosis of metabolic syndrome. Statistical analysis of the data was done using statistical processing software (SPSS-17). RESULTS Metabolic syndrome was significantly more common in psoriatic patients than in controls (28.8% vs 16.7%, p=0.01). Hypertriglyceridemia was significantly more prevalent in cases than in controls (34% vs 20.5%, p=0.008). The reduced HDL levels also showed a significantly high occurrence among cases (27.6% vs 13.5%, p=0.002). Moderate increase of blood pressure was seen among cases as compared to controls but the difference was not statistically significant (p=0.1). Impaired blood glucose and abdominal obesity were similar in both groups. Smoking and alcoholism did not influence the association of metabolic syndrome with psoriasis. There was no correlation of metabolic syndrome with severity and duration of psoriasis. CONCLUSION Our findings suggest that metabolic syndrome as well as dyslipidemia is common in psoriasis patients among urban South Indians. This study highlights the need for screening at diagnosis and regular follow up of the metabolic aspects of the disease along with the skin lesions.

Abstract
Although studies regarding prevalence of metabolic syndrome (MS) in Asian psoriatic patients are limited and show varying results, a previous report describes a significant increase in prevalence of MS in Thai psoriatic patients, as compared with rates in the general population. However, no significant association between MS and psoriasis severity using the Psoriasis Area and Severity Index (PASI) was found, which differs from the findings of Korean and Japanese studies. This study aimed at re-evaluating the association between MS and psoriasis severity in Thai patients using current assessment (PASI) and chronological assessment (historical course and interventions). A total of 273 psoriatic patients were recruited. After controlling for age and sex, 96 patients were assigned to the MS group and 96 patients to the non-MS group. Similar to the previous study, no significant differences were identified between metabolic and non-metabolic patients regarding PASI, age of onset, disease duration and family history of psoriasis. However, the numbers of hospitalizations (P = 0.018) and interventions (P = 0.028) were significantly higher in metabolic patients than in non-metabolic patients. Further, a greater number of metabolic components was significantly associated with a higher number of hospitalizations (P = 0.012), pustular or erythrodermic psoriasis episodes (P = 0.049), and interventions (P = 0.005). Body mass index of 23 kg/m2 or more, abdominal obesity and high blood pressure were associated with an increased risk of treatment failure. Using chronological assessment, our study supported that MS negatively affects psoriasis severity and treatment outcomes. Screening for MS is highly recommended for psoriatic patients.

Abstract
Background: Osteopontin (OPN) has been postulated to have a role in several T-helper (Th) 1 and Th 17-mediated diseases including psoriasis (PS), through multiple mechanisms sharing in the onset and worsening of PS, OPN shares in induction of keratinocyte proliferation through inhibiting keratinocyte apoptosis, OPN acts as a proinflammatory agent that participates in the upregulation of Th cell lineages, among which are the Th 1 and Th 17 cells. Aims and Objectives: The aim of this study was to explore the possible role of OPN in the pathogenesis of PS. Materials and Methods: This case–control study was carried out on 18 patients of chronic plaque PS (mean age 37.61 ± 14.48) and a control group of 18 apparently healthy volunteers (mean age 41.11 ± 11.02 years). Severity of PS was assessed using the PS area and severity index score. Two skin biopsies were taken from psoriatic patients. The first was taken from the lesional skin and the other from a counter apparently healthy site. Results: Our results showed statistically significant differences in the expression of OPN, between lesional and nonlesional skin as well as between nonlesional skin and control group (P ≤ 0.001). In addition, there was a significant difference in the expression of OPN, between control and lesional group. Conclusions: OPN involvement in PS enlarges the list of cytokines able to stimulate the inflammatory response in this disease, anti-OPN antibodies, may eventually become a useful therapeutic approach in PS.

Abstract
Psoriasis and psoriatic arthritis are associated with a significantly increased risk of cardiovascular risk factors and major adverse cardiovascular events (MACE). Active research is ongoing to elucidate this relationship between psoriatic diseases and cardiovascular comorbidities, as well as their shared pathogenic mechanisms. This review focuses on (1) the epidemiologic association between psoriasis and cardiovascular risk factors, (2) the epidemiologic association between psoriasis and MACE, (3) the epidemiologic association between psoriatic arthritis, cardiovascular risk factors, and MACE, and (4) proposed mechanisms for the contribution of psoriatic diseases to cardiovascular diseases. The proposed mechanisms for shared pathogenesis between psoriatic diseases and cardiovascular diseases are inflammation, insulin resistance, dyslipidemia, angiogenesis, oxidative stress, and endothelial dysfunction. There is complex interplay and overlap among these mechanisms and their contributions to shared pathogenesis. Future translational research is necessary to elucidate the link between psoriatic diseases and cardiovascular diseases. Such findings may be applied clinically to improve the lives of psoriasis patients.

Abstract
OBJECTIVE Osteopontin (OPN) is a sialoprotein implicated in different immunity and metabolic pathways. Capable of activating dendritic cells and inducing Th1-Th17-mediated tissue damage, OPN plays a significant role in the development/progression of several autoimmune diseases; interestingly, it was also shown that OPN participates in the acute pancreatic islets response to experimentally induced diabetes in non-obese diabetic (NOD) mice. Furthermore, OPN promotes adipose tissue dysfunction, systemic inflammation and insulin resistance. Our aims of this study were to evaluate circulating OPN levels in adult patients with type 1 diabetes mellitus (T1DM) compared to non-diabetic control participants and to unravel clinical and biochemical correlates of OPN concentration. DESIGN Case-control study. METHODS We enrolled 54 consecutive T1DM patients referred to our diabetes outpatient clinic at Sapienza University of Rome and 52 healthy sex and age-comparable controls. The study population underwent clinical evaluation, blood sampling for biochemistry and complete screening for diabetes complications. Serum OPN levels were measured by MILLIPLEX Multiplex Assays Luminex. RESULTS T1DM patients had significantly higher serum OPN levels than controls (17.2±12.9 vs 10.5±11.6 mg/ml, P=0.009). OPN levels correlated with T1DM, higher blood pressure, BMI, creatinine, γ-GT, ALP and lower HDL; the association between high OPN levels and T1DM was independent from all confounders. No correlation was shown between OPN and HbA1c, C-peptide, insulin requirement, co-medications and diabetes duration. CONCLUSIONS This study demonstrates for the first time in a case-control study that adults with T1DM have increased serum OPN levels, and that higher OPN concentrations are associated with an unfavorable metabolic profile in these patients.

Abstract
BACKGROUND The association between psoriasis and cardiovascular disease is well documented, but the underlying mechanisms remain unknown. The relationship between osteopontin and psoriasis has been studied. High serum levels of osteopontin are reported in psoriasis, with increased cardiovascular risk factors in these patients. OBJECTIVES We evaluate the extent of subclinical atherosclerosis by measuring the mean intima-media wall thickness (MIMT) of the common carotid artery (CCA) in patients with psoriasis and assessing its correlation with osteopontin to identify vascular risk factors associated with psoriasis. METHODS Intima-media wall thickness of the CCA and plasma osteopontin were determined in 40 patients and 40 age- and sex-matched healthy control subjects. RESULTS Median serum osteopontin was significantly higher in patients with psoriasis than in healthy control subjects. Mean intima-media wall thickness of the CCA was positively associated with plasma osteopontin level (r = 0.47, P < 0.0001), body mass index (r = 0.62, P < 0.0001), age (r = 0.54, P < 0.0001), total cholesterol (r = 0.54, P < 0.0001), and triglycerides (r = 0.65, P < 0.0001). CONCLUSIONS This study shows higher levels of plasma osteopontin and MIMT-CCA in psoriasis patients than in healthy controls. This is the first study to show a positive correlation between plasma osteopontin and MIMT-CCA.

Abstract
BACKGROUND The association between psoriasis and cardiovascular diseases is well documented, but the underlying mechanisms remain unknown. Overexpression of osteopontin (OPN) has been reported in the plasma of patients with psoriasis, with increased cardiovascular risk factors in these patients. Selenium compounds are effective in downregulating OPN expression. OBJECTIVE We investigated the levels of OPN, selenium and prolactin (PRL) in psoriasis, and their association with metabolic status in patients to identify a possible link between these markers and observed comorbidities. METHODS Plasma samples from 40 patients with psoriasis and 40 age- and sex-matched healthy controls (HCs) were collected for ELISA. The clinical significance of plasma OPN, selenium and PRL levels in patients compared with controls was analysed in relation to metabolic disorders. RESULTS There was no significant difference in median serum selenium levels between the two groups. Serum levels of PRL were not significantly different from those of HCs, but levels of OPN were significantly higher in patients with psoriasis than in HCs. CONCLUSIONS High plasma OPN is a predictor for occurrence of psoriasis. Our study showed that serum selenium and PRL were not decreased in patients with psoriasis, but there was a negative statistically significant correlation between OPN and selenium in all participants.

Abstract
Previous studies have demonstrated that osteopontin (OPN) levels are elevated in the synovial fluid and articular cartilage, and are associated with the severity of knee osteoarthritis (OA). However, the role of OPN in the pathogenesis of OA has yet to be elucidated. The present study aimed to investigate the effects of OPN on the expression of the aggrecanases, a disintegrin and metalloproteinase with thrombospondin motifs (ADAMTS)4 and ADAMTS5, in human OA chondrocytes, as they serve a key function in aggrecan degradation. Human OA chondrocytes were obtained from the knees of 16 patients with OA, and subsequently cultured in a monolayer. The chondrocytes were divided into three groups, which included the control (no treatment), N-OPN (treated with 100 ng/ml OPN, the normal circulating OPN concentration) and the H-OPN groups (treated with 1 µg/ml OPN, a high OPN concentration). Reverse transcription-quantitative polymerase chain reaction was performed to quantify the relative mRNA expression levels of ADAMTS4, ADAMTS5 and aggrecan in the chondrocytes. The mRNA expression levels of ADAMTS4 were significantly reduced in the N-OPN and H-OPN groups when compared with the control group (P<0.0001). In addition, the mRNA expression levels of ADAMTS4 were lower in the H-OPN group when compared with the N-OPN group (P<0.001). However, no statistically significant difference was observed in the relative mRNA expression levels of ADAMTS5 among the three groups (P>0.05). Furthermore, the mRNA expression levels of aggrecan were higher in the N-OPN and H-OPN groups when compared with the control group (P<0.0001), and a statistically significant difference was observed between the N-OPN and H-OPN groups with regard to the mRNA expression of aggrecan (P<0.0001). These results demonstrated that OPN may exert a protective effect in human OA chondrocytes against aggrecan degradation by suppressing the expression of ADAMTS4.

Chen T, Sun L, He C, Gong Y, Xu Q, Yuan Y. Serum OPN expression for identification of gastric cancer and atrophic gastritis and its influencing factors. PLoS One 2014; 9:e114005. [PMID: 25479069 PMCID: PMC4257596 DOI: 10.1371/journal.pone.0114005] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2014] [Accepted: 11/03/2014] [Indexed: 01/08/2023] Open
Abstract
Background Most studies have found that osteopontin (OPN) expression level is related to the poor prognosis of gastric cancer. However, few studies have examined the relationship between OPN expression and gastric precancerous diseases, and the potential role of OPN in the formation and development of GC. We investigated the relationships between serum OPN levels and the risks of gastric cancer (GC) and its precancerous disease, to explore the diagnostic efficacy of serum OPN level for GC and atrophic gastritis and its influencing factors. Methods A total of 1,452 patients were enrolled, including 609 with mild superficial gastritis (SG), 594 with atrophic gastritis (AG) and 249 with GC. The levels of serum OPN and serum Helicobacter pylori IgG antibody were detected by enzyme-linked immunosorbent assay. Results Serum OPN levels increased from mild SG (1.99±1.91 ng/ml) to AG (2.37±2.27 ng/ml) to GC (5.94±4.52 ng/ml) (P≤0.002), along with increasing severity of gastric disease. OPN levels were significantly higher in patients with GC compared with the non-cancer population (2.17±2.10, P<0.0001). Serum OPN level was positively correlated with age and was higher in men than women, but was not correlated with H. pylori infection status. The area under the receiver operating characteristic curve was 0.805, the optimal cutoff was 2.56 ng/ml and the sensitivity and specificity were 74.3% and 71.8%, respectively, for the ability of serum OPN to discriminate GC. Conclusions Serum OPN expression was closely related to the risks of GC and AG, and it might be a useful marker for the discrimination of GC. OPN level was positively correlated with age and male sex, but was not affected by H. pylori infection, and it was promoted by smoking and drinking, in patients with mild SG.

Abstract
The prevalence of metabolic syndrome in Asian psoriatic patients compared with that of the general population shows variable results. This study aimed to examine the association between psoriasis and metabolic syndrome in a Thai population. This case-control study included 199 psoriatic patients and 199 controls matched for sex and age from the general Thai population. There were 111 men (55.8%) and 88 women (44.2%) in both the psoriatic and control groups. The mean age (± standard deviation) of both groups was 50.04 ± 13.81 and 49.96 ± 14.39 years (P = 0.91), respectively. The majority of psoriatic cases (82.9%) were of plaque type. The prevalence of metabolic syndrome was significantly higher in psoriatic patients than in the general population at 49.25% versus 30.65%. After controlling for age, sex, smoking and alcohol drinking the odds ratio was 2.25 (P < 0.0001). The metabolic components which were significantly higher in the cases than controls included hyperglycemia, high blood pressure (HBP) and abdominal obesity. No statistically significant difference was found between the cases and controls regarding prevalence of obesity, hypertriglyceridemia and low high-density lipoprotein cholesterol. Thai psoriatic patients had a higher prevalence of metabolic syndrome than the general population. In conclusion, the prevalence of HBP, hyperglycemia and abdominal obesity was significantly higher in cases than in controls.

Correlation between ovarian neoplasm and serum levels of osteopontin: a meta-analysis. Tumour Biol 2014; 35:11799-808. [PMID: 25192720 DOI: 10.1007/s13277-014-2314-1] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2014] [Accepted: 07/04/2014] [Indexed: 01/11/2023] Open
Abstract
The aim of this meta-analysis was to evaluate the clinical significance of serum osteopontin (OPN) levels in ovarian neoplasm in patients, with the goal of building a novel diagnostic score model. By searching the PubMed, Embase, Web of Science, Cochrane Library, CISCOM, CINAHL, Google Scholar, CBM, and China National Knowledge Infrastructure (CNKI) databases, we conducted a meta-analysis. Studies were pooled, and the standardized mean difference (SMD) and its corresponding 95 % confidence interval (CI) were calculated. Subgroup analyses and publication bias detection were also conducted. Version 12.0 STATA software was used for statistical analysis. We performed a final analysis of 1,653 subjects altogether (822 patients with psoriasis and 831 healthy controls) from 15 clinical case-control studies. The meta-analysis results showed a positive association between serum OPN levels and ovarian neoplasm (SMD = 2.60, 95 %CI 1.88-3.32, P < 0.001). The subgroup analysis by ethnicity detected that high levels of serum OPN may be the main risk factor for ovarian neoplasms in Asians (SMD = 2.91, 95 %CI 2.38-3.45, P < 0.001), but not in Caucasians (P > 0.05). The present meta-analysis indicated that serum OPN levels were generally elevated in ovarian neoplasm patients, and thus, serum levels of OPN could be useful in diagnosing ovarian neoplasm.

Abstract
BACKGROUND Emerging evidence supports the view that selenoproteins are essential for maintaining bone health. SCOPE OF REVIEW The current state of knowledge concerning selenoproteins and Se status in bone physiology and pathology is summarized. MAJOR CONCLUSIONS Antioxidant selenoproteins including glutathione peroxidase (GPx) and thioredoxin reductase (TrxR), as a whole, play a pivotal role in maintaining bone homeostasis and protecting against bone loss. GPx1, a major antioxidant enzyme in osteoclasts, is up-regulated by estrogen, an endogenous inhibitor of osteoclastogenesis. TrxR1 is an immediate early gene in response to 1α,25-dihydroxyvitamin D3, an osteoblastic differentiation agent. The combination of 1α,25-dihydroxyvitamin D3 and Se generates a synergistic elevation of TrxR activity in Se-deficient osteoblasts. Of particular concern, pleiotropic TrxR1 is implicated in promoting NFκB activation. Coincidentally, TrxR inhibitors such as curcumin and gold compounds exhibit potent osteoclastogenesis inhibitory activity. Studies in patients with the mutations of selenocysteine insertion sequence-binding protein 2, a key trans-acting factor for the co-translational insertion of selenocysteine into selenoproteins have clearly established a causal link of selenoproteins in bone development. Se transport to bone relies on selenoprotein P. Plasma selenoprotein P concentrations have been found to be positively correlated with bone mineral density in elderly women. GENERAL SIGNIFICANCE A full understanding of the role and function of selenoproteins and Se status on bone physiology and pathology may lead to effectively prevent against or modify bone diseases by using Se.

Abstract
BACKGROUND Osteoprotegerin (OPG), osteopontin (OPN) and matrix Gla protein (MGP) are markers of bone metabolism but they are also involved in vascular calcification. However, their precise role is not completely understood. Arterial stiffness is considered an independent predictor of cardiovascular events and it may be one of the causes of the increased cardiovascular risk associated with postmenopausal status. Medial and intimal calcification may increase arterial stiffness. The aim of our study was to assess the relationship of OPG, OPN and MGP with aortic pulse wave velocity (aPWV) as a marker of arterial stiffness in postmenopausal women. MATERIALS AND METHODS Circulating OPG, OPN and serum total MGP were measured in 144 postmenopausal women using the enzyme-linked immunosorbent assay method. Aortic PWV was determined by an oscillometric method. RESULTS Osteoprotegerin correlated with age (p<0.001, r=0.27), aPWV (p<0.001, r=0.32) and hypersensitive C reactive protein (hsCRP) (p<0.001, r=0.37), OPN correlated directly with hsCRP (p<0.001, r=0.39) and inversely with high density lipoprotein cholesterol (p=0.02, r=-0.02). No significant association was found between total MGP and clinical, biochemical and vascular parameters. The correlation between OPG and aPWV persisted even after the adjustment for various potential confounders (p=0.02, r=0.19). In multiple regression analysis in the whole study population the most important predictors of aPWV were OPG (β=0.230, p=0.006), hsCRP (β=0.212, p=0.01) and systolic blood pressure (β=0.163, p=0.04). After exclusion of patients treated with statins the independent predictors were hsCRP (β=0.275, p=0.005) and OPG (β=0.199, p=0.04). CONCLUSION Circulating OPG, but not OPN and total MGP, is associated with aPWV and may be a marker of the increased arterial stiffness and cardiovascular risk in postmenopausal women.

Abstract
BACKGROUND Osteopontin (OPN) is a pleiotropic protein with important roles in inflammation and immunity that has been suggested as a candidate biomarker for disease activity in multiple sclerosis (MS). OBJECTIVE We evaluated plasma levels of OPN in an unselected cohort of MS patients, to determine its potential as a biomarker for disease subtype and/or disease activity in a regular clinical setting. METHODS We analyzed OPN plasma levels in 492 consecutive MS patients, using a commercial enzyme-linked immunosorbent assay (ELISA). RESULTS OPN levels were higher in relapsing-remitting and secondary progressive MS, compared to healthy controls. Treatment with natalizumab or glatiramer acetate was associated with lower OPN levels. There was no significant association between the OPN levels and disease activity, as measured by clinical or radiological criteria. One-third of patients with high OPN levels had concurrent disorders that may also be associated with increased OPN expression, and which may mask a modest effect of MS disease activity on OPN levels. CONCLUSION Our data do not support a role for circulating OPN levels as a biomarker for disease activity in a heterogeneous clinical setting, but does not rule out a potential role in the cerebrospinal fluid, in a controlled setting such as a clinical trial, or in concert with other biomarkers.

Abstract
Psoriasis, a systemic inflammatory disease, is associated with enhanced atherosclerosis and risk of cardiovascular (CV) disease, which may account for higher morbidity and mortality rates in psoriatic patients. It especially applies to younger psoriatic patients with more severe disease, reducing their life expectancy. The aim of the study was to review the literature on CV disease in psoriasis as well as the pathogenic mechanisms shared between psoriasis and atherosclerosis. Moreover, case-control and cohort studies published between 2006 and 2011 were selected for meta-analysis. The meta-analysis indicates elevated risk of cardiovascular events in psoriatic patients in relation to non-psoriatic controls (OR 1.28; 95% CI 1.18-1.38). It is suggested that the treatment of the inflammatory processes involved in the pathogenesis of both psoriasis and atherosclerosis may be beneficial in reducing the CV risk in psoriatic patients. Further in-depth investigations, including prospective studies, are needed to enable more effective management of psoriatic patients in the future.

Abstract
Population-based observational studies have suggested a relationship between psoriasis and hypertension. We performed a systematic review and meta-analysis to better understand the association between psoriasis and hypertension. We systematically searched MEDLINE, EMBASE, and the Cochrane Central Register from 1 January 1980 to 1 January 2012. Two authors independently assessed trial eligibility and quality. We applied the Meta-Analysis of Observational Studies in Epidemiology guidelines in the conduct of this study. We identified 24 observational studies with a total of approximately 2.7 million study participants fulfilling our inclusion criteria. Among them, 309 469 were patients with psoriasis. On the basis of random effects modeling of case-control and cross-sectional studies, the odds ratio (OR) for hypertension among patients with psoriasis was 1.58 [95% confidence interval (CI) 1.42-1.76] compared with the controls. The OR for hypertension among patients with mild psoriasis was 1.30 (95% CI 1.15-1.47) and the OR for hypertension among patients with severe psoriasis was 1.49 (95% CI 1.20-1.86) compared with the controls. Two cohort studies examining incidence of hypertension found that psoriasis was associated with a hazard ratio of 1.09 (95% CI 1.05-1.14) and 1.17 (95% CI 1.06-1.30) for development of hypertension. In a subgroup analysis, patients with psoriatic arthritis also had an increased prevalence of hypertension (OR 2.07, 95% CI 1.41-3.04). Psoriasis and psoriatic arthritis are associated with greater prevalence of hypertension. Patients with severe psoriasis have greater odds of hypertension than those with mild psoriasis.

Abstract
BACKGROUND Increasing population-based studies have suggested a relationship between psoriasis and metabolic syndrome. OBJECTIVE The objective of this study was to perform a systematic review and meta-analysis that synthesizes the epidemiologic associations between psoriasis and metabolic syndrome. METHODS We searched for observational studies from MEDLINE, EMBASE, and Cochrane Central Register from Jan 1, 1980 to Jan 1, 2012. We applied the Meta-Analysis of Observational Studies in Epidemiology (MOOSE) guidelines in the conduct of this study. RESULTS We identified 12 observational studies with a total of 1.4 million study participants fulfilling the inclusion criteria, among whom 41,853 were patients with psoriasis. Based on random-effects modeling of cross-sectional and case-controlled studies, the pooled odds ratio (OR) for metabolic syndrome among patients with psoriasis was 2.26 (95% confidence interval [CI] 1.70-3.01) compared with the general population. Visual inspection of a funnel plot and formal analysis with the Egger test suggested publication bias and absence of small studies in the published literature (P = .03). A dose-response relationship was also observed between psoriasis severity and prevalence of metabolic syndrome. LIMITATIONS No studies to date have assessed incidence of metabolic syndrome among patients with psoriasis. CONCLUSIONS Compared with the general population, psoriasis patients have higher prevalence of metabolic syndrome, and patients with more severe psoriasis have greater odds of metabolic syndrome than those with milder psoriasis.

Abstract
Psoriasis is a systemic, immune-mediated disorder, characterized by inflammatory skin and joint manifestations. A range of co-morbidities is associated with psoriasis, including metabolic diseases, such as diabetes, and psychological disorders. Although the systemic nature of psoriasis often remains unrecognized, the inflammatory processes involved may be associated with the development of co-morbidities, which, themselves, have a significant impact on the patient's health and quality of life. The relative risks of myocardial infarction (MI) and stroke are increased in patients with psoriasis compared with the general population. These are especially seen in younger patients with more severe disease, and are believed to contribute to the 3- to 4-year reduction in life expectancy among patients with severe psoriasis. The recent results of large studies indicate that the increased cardiovascular (CV) risk is at least partially attributable to psoriasis and independent of the presence of metabolic co-morbidities. The possible interplay between psoriasis and CV disease is complex. Metabolic diseases such as obesity and diabetes have overlapping genetic predispositions with psoriasis. Both conditions are likely to also interact at a functional level because obesity and the up-regulation of pro-inflammatory mediators in psoriasis appear to influence adipocyte homoeostasis, inducing non-professional immune functions. This may perpetuate psoriatic inflammation, displaying similarities to the immunopathogenesis of atherosclerosis. Finally, the disturbed adipokine profile and inflammation associated with psoriasis enhances insulin resistance, causing subsequent endothelial dysfunction, atherosclerosis and eventual coronary events. The differential contribution of psoriasis and uncontrolled classical CV risk factors to the increased CV risk seen in psoriasis patients is not clear. Successful treatment with methotrexate appears to lower the rates of MI in patients with psoriasis. Tumour necrosis factor-α (TNF-α) inhibitors are known to counteract insulin resistance and emerging studies demonstrate an even higher protective effect of TNF-α antagonist therapy against the development of diabetes or CV co-morbidities in patients. The recent data reviewed here indicate a role for earlier and more appropriate treatment of psoriasis with drugs such as TNF-α antagonists. Such an approach has the potential to significantly improve patient outcomes through the treatment of psoriasis itself and possibly also in protection against co-morbidities.

Psoriasis is a chronic skin inflammatory disease in which a pleiotropic cytokine, tumor necrosis factor alpha (TNF-α), plays a central role, as demonstrated by the clinical success of anti-TNF-α therapy. Among the multiple effects of TNF-α on keratinocytes, the induction of matrix metalloproteinase-9 (MMP-9), a collagenase implicated in joint inflammation, might be one of the key mechanisms in psoriasis pathogenesis. Interestingly, MMP-9 expression can be enhanced also by osteopontin (OPN), a glycosylated protein whose levels are increased in skin and peripheral blood mononuclear cells (PBMC) of psoriasis patients. The aim of the current study is to investigate the relationship between OPN, MMP-9 and TNF-α in psoriasis. Our survey identified high levels of both OPN and MMP-9 in PBMC as well as skin of psoriatic patients with respect to healthy controls. Significant reduction of OPN and MMP-9 levels in PBMC, plasma and lesional skin of psoriasis patients was observed after 24 weeks of anti-TNF-α therapy. Moreover, OPN and MMP-9 were enhanced by TNF-α and down-regulated by anti-TNF-α treatment in healthy PBMC. These findings may suggest that OPN and MMP-9 may be regulated by TNF-α, indicating a possible role in the pathogenesis of psoriasis.

Abstract
BACKGROUND Alefacept is a remittive treatment for generalized psoriasis but is rarely used due to its erratic efficacy. OBJECTIVE To determine if psoriasis plaques will respond to intralesional alefacept and if this predicts a systemic response to intramuscular (IM) alefacept. METHODS We describe a 25-week, single-center, open-label study. Patients received weekly intralesional alefacept of increasing concentrations into target plaques for 3 weeks followed by IM injections for 12 weeks and concluded with an observation period of 9 weeks. The psoriasis area and severity index (PASI) was used to assess the efficacy of IM alefacept. RESULTS Interim results are reported for the first seven patients enrolled. Two patients responded intralesionally to the most dilute 1:100 concentration of alefacept to sterile water and achieved a 59% and 100% improvement in PASI. Five patients did not respond intralesionally to the most dilute form of alefacept and none achieved PASI 75. Two of these five patients did not respond to any concentration and achieved a 26% and 38% improvement in PASI. Limitations to this study include a small sample size and being non-placebo-controlled. CONCLUSION Alefacept is effective intralesionally and may predict a systemic response - challenging the concept that biologics must work systemically.

Abstract
Current epidemiological data support the association between psoriasis and cardiovascular (CV) risk, in apparent correlation with psoriasis severity. Although less unanimously, evidence of an increased prevalence of CV diseases among psoriasis patients has been reported, including ischemic heart disease, cerebrovascular, peripheral vascular and heart structural disorders. In particular, various studies showed a correlation between psoriasis and major CV events (i.e., myocardial infarction, stroke), while others investigated subclinical changes of blood vessels, such as intima-media thickness increase, arterial stiffness and coronary artery calcification. A series of different mechanisms, like traditional CV risk or iatrogenic risk factors, inflammation, hemostasis dysregulation, hyperhomocysteinemia, and shared genetic susceptibility, are thought to underlie this epidemiological association. Among these elements, inflammation and its related cytokine milieu, including Th1-mediated response and Th17/Treg imbalance, C reactive protein and the newly implicated osteopontin are considered to play a primary role, even if yet to be fully understood.

Abstract
Psoriasis is a common disease with the population prevalence ranging from 2% to 3%. Its prevalence in the population is affected by genetic, environmental, viral, infectious, immunological, biochemical, endocrinological, and psychological factors, as well as alcohol and drug abuse. In the recent years, psoriasis has been recognised as a systemic disease associated with numerous multiorgan abnormalities and complications. Dyslipidemia is one of comorbidities in psoriatic patients. Lipid metabolism studies in psoriasis have been started at the beginning of the 20th century and are concentrated on skin surface lipids, stratum corneum lipids and epidermal phospholipids, serum lipids, dermal low-density lipoproteins in the psoriatic skin, lipid metabolism, oxidative stress and correlations between inflammatory parameters, lipid parameters and clinical symptoms of the disease. On the basis of the literature data, psoriasis can be described as an immunometabolic disease.

Abstract
OBJECTIVE To investigate osteopontin (OPN) levels in both synovial fluid and articular cartilage of patients with primary knee osteoarthritis (OA) and their relationship with severity of the disease. METHOD Fifty patients aged 48-81 years with knee OA and 10 healthy controls were enrolled in this study. Anteroposterior knee radiographs or/and Mankin score were taken to determine the disease severity of the affected knee. The radiographic grading of OA in the knee was performed by using the Kellgren-Lawrence criteria. OPN levels in synovial fluid were measured using enzyme-linked immunosorbent assay. OPN levels in articular cartilage were assessed by immunohistochemical methods. RESULTS Compared to healthy controls, OA patients had higher OPN concentration in synovial fluid (4519.60+/-1830.37, 95%CI 3999.42-5039.79 vs 1179.70+/-303.39, 95%CI 1035.53-1438.74 pg/ml, P<0.001)and articular cartilage(0.6+/-0.06, 95%CI 0.59-0.62 vs 0.43+/-0.07, 95%CI 0.38-0.48, P<0.01). In addition, synovial fluid OPN levels showed a positive correlation with articular cartilage OPN levels (r=0.411, 95%CI 0.150-0.619, P=0.003). Subsequent analysis showed that synovial fluid OPN levels significantly correlated with severity of disease (Spearman's rho=0.581, 95%CI 0.335-0.726, P<0.001). Furthermore, the articular cartilage levels of OPN also correlated with disease severity (Spearman's rho=0.675, 95%CI 0.500-0.808, P<0.001). CONCLUSIONS OPN in synovial fluid and articular cartilage is associated with progressive joint damage and is likely to be a useful biomarker for determining disease severity and progression in knee OA.

Abstract
Osteopontin (OPN) is a glycoprotein expressed by various tissues and cells. The existence of variant forms of OPN as a secreted (sOPN) and intracellular (iOPN) protein and its modification through post-translational modification and proteolytic cleavage explain its broad range of functions. There is increasing knowledge which receptors OPN isoforms can bind to and which signaling pathways are activated to mediate different OPN functions. sOPN interacts with integrins and CD44, mediates cell adhesion, migration and tumor invasion, and has T helper 1 (Th1) cytokine functions and anti-apoptotic effects. iOPN has been described to regulate macrophage migration and interferon-alpha secretion in plasmacytoid dendritic cells. Both sOPN and iOPN, through complex functions for different dendritic cell subsets, participate in the regulation of Th cell lineages, among them Th17 cells. For skin disease, OPN from immune cells and tumor cells is of pathophysiological relevance. OPN is secreted in autoimmune diseases such as lupus erythematosus, and influences inflammation of immediate and delayed type allergies and granuloma formation. We describe that OPN is overexpressed in psoriasis and propose a model to study OPN function in psoriatic inflammation. Through cytokine functions, OPN supports immune responses against Mycobacteria and viruses such as herpes simplex virus. OPN is also implicated in skin tumor progression. Overexpression of OPN influences invasion and metastasis of melanoma and squamous cell carcinoma cells, and OPN expression in melanoma is a possible prognostic marker. As OPN protein preparations and anti-OPN antibodies may be available in the near future, in-depth knowledge of OPN functions may open new therapeutic approaches for skin diseases.

Abstract
Rheumatoid arthritis (RA) patients are characterized by increased arterial stiffness, an independent predictor of cardiovascular risk. It has been suggested that osteopontin (OPN), a cytokine involved in RA pathogenesis, might have vascular effects. To study a possible relationship between OPN and arterial stiffness, aortic pulse wave velocity (PWV) was measured by tonometry in 69 patients (41 with RA, 28 with systemic sclerosis [SSc]) and 18 healthy controls. Plasma OPN levels, oxidative stress markers, and endothelin 1 (ET-1) were assessed. OPN levels were significantly (P < 0.05) higher in RA (median 9.93, range 4.36-47.80 ng/mL) than in SSc (4.3, 2.1-19.7 ng/mL) or controls (5.2, 4.1-9.4 ng/mL). In RA patients, log-OPN was related to log-C-reactive protein (log-CRP) (r = 0.30, P < 0.05), age (r = 0.38, P < 0.01), Health Assessment Questionnaire (HAQ) (r = 0.58, P < 0.0001), and inversely related to total cholesterol (r = -0.33, P < 0.05) and apolipoprotein A (apoA) (r = -0.58, P < 0.001), but not to oxidative stress markers and ET-1. PWV was similar in RA (median 8.1, range 4.7-16.4 m/s) and SSc (median 8.7, range 7.1-13.1 m/s), but significantly greater (P < 0.01) than controls (median 7.5, range 4.1-10.4 m/s). Aortic PWV was related to log-OPN (r = 0.40, P < 0.01) only in RA patients. It also was related to age (r = 0.34, P < 0.05), mean blood pressure (r = 0.44, P < 0.001), and HAQ (r = 0.48, P < 0.001). In multiple regression analysis (r(2) = 0.36), including confounders, log-OPN remained a significant predictor (P < 0.05) of PWV in RA. Elevated plasma OPN levels are associated with increased arterial stiffness in RA patients, suggesting that this protein might represent a bridge protein between inflammation and the consequent joint damage and cardiovascular risk in RA patients.
