Abstract
PURPOSE Accurately identifying patients with psoriasis (PsO) is crucial for generating real-world evidence on PsO disease course and treatment utilization. METHODS We developed nine claims-based algorithms for PsO using a combination of the International Classification of Diseases (ICD)-9 codes, specialist visit, and medication dispensing using Medicare linked to electronic health records data (2013-2014) in two healthcare provider networks in Boston, Massachusetts. We calculated positive predictive value (PPV) and 95% confidence interval (CI) for each algorithm using the treating physician's diagnosis of PsO via chart review as the gold standard. Among the confirmed PsO cases, we assessed their PsO disease activity. RESULTS The nine claims-based algorithms identified 990 unique patient records. Of those, 918 (92.7%) with adequate information were reviewed. The PPV of the algorithms ranged from 65.1 to 82.9%. An algorithm defined as ≥1 ICD-9 diagnosis code for PsO and ≥1 prescription claim for topical vitamin D agents showed the highest PPV (82.9%). The PPV of the algorithm requiring ≥2 ICD-9 diagnosis codes and ≥1 prescription claim for PsO treatment excluding topical steroids was 81.1% but higher (82.5%) when ≥1 diagnosis was from a dermatologist. Among 411 PsO patients with adequate information on PsO disease activity in EHRs, 1.5-5.8% had no disease activity, 31.3-36.8% mild, and 26.9-35.1% moderate-to-severe across the algorithms. CONCLUSIONS Claims-based algorithms based on a combination of PsO diagnosis codes and dispensing for PsO-specific treatments had a moderate-to-high PPV. These algorithms can serve as a useful tool to identify patients with PsO in future real-world data pharmacoepidemiologic studies.

Abstract
Background Psoriasis is an inflammatory skin disease associated with multiple comorbidities and substantially diminishes patients’ quality of life. The gut microbiome has become a hot topic in psoriasis as it has been shown to affect both allergy and autoimmunity diseases in recent studies. Our objective was to identify differences in the fecal microbial composition of patients with psoriasis compared with healthy individuals to unravel the microbiota profiling in this autoimmune disease. Results We collected fecal samples from 30 psoriasis patients and 30 healthy controls, sequenced them by 16S rRNA high-throughput sequencing, and identified the gut microbial composition using bioinformatic analyses including Quantitative Insights into Microbial Ecology (QIIME) and Phylogenetic Investigation of Communities by Reconstruction of Unobserved States (PICRUSt). Our results showed that different relative abundance of certain bacterial taxa between psoriasis patients and healthy individuals, including Faecalibacterium and Megamonas, were increased in patients with psoriasis. It’s also implicated that many cytokines act as main effect molecules in the pathology of psoriasis. We selected the inflammation-related indicators that were abnormal in psoriasis patients and found the microbiome variations were associated with the level of them, especially interleukin-2 receptor showed a positive relationship with Phascolarctobacterium and a negative relationship with the Dialister. The relative abundance of Phascolarctobacterium and Dialister can be regard as predictors of psoriasis activity. The correlation analysis based on microbiota and Inflammation-related indicators showed that microbiota dysbiosis might induce an abnormal immune response in psoriasis. Conclusions We concluded that the gut microbiome composition in psoriasis patients has been altered markedly and provides evidence to understand the relationship between gut microbiota and psoriasis. More mechanistic experiments are needed to determine whether the differences observed in gut microbiota are the cause or consequences of psoriasis and whether the relationship between gut microbiota and cytokines was involved.

Abstract
Psoriasis is an inflammatory skin disease with complex pathogenesis and multiple etiological factors. Besides the essential role of autoreactive T cells and constellation of cytokines, the discovery of IL-23/Th17 axis as a central signaling pathway has unraveled the mechanism of accelerated inflammation in psoriasis. This has provided insights into psoriasis pathogenesis and revolutionized the development of effective biological therapies. Moreover, genome-wide association studies have identified several candidate genes and susceptibility loci associated with this disease. Although involvement of cellular innate and adaptive immune responses and dysregulation of immune cells have been implicated in psoriasis initiation and maintenance, there is still a lack of unifying mechanism for understanding the pathogenesis of this disease. Emerging evidence suggests that psoriasis is a high-mortality disease with additional burden of comorbidities, which adversely affects the treatment response and overall quality of life of patients. Furthermore, changing trends of psoriasis-associated comorbidities and shared patterns of genetic susceptibility, risk factors and pathophysiological mechanisms manifest psoriasis as a multifactorial systemic disease. This review highlights the recent progress in understanding the crucial role of different immune cells, proinflammatory cytokines and microRNAs in psoriasis pathogenesis. In addition, we comprehensively discuss the involvement of various complex signaling pathways and their interplay with immune cell markers to comprehend the underlying pathophysiological mechanism, which may lead to exploration of new therapeutic targets and development of novel treatment strategies to reduce the disastrous nature of psoriasis and associated comorbidities.

Abstract
Psoriasis is a debilitating skin disease characterized by epidermal thickening, abnormal keratinocyte differentiation, and proinflammatory immune cell infiltrate into the affected skin. IL-17A plays a critical role in the etiology of psoriasis. ACT1, an intracellular adaptor protein and a putative ubiquitin E3 ligase, is essential for signal transduction downstream of the IL-17A receptor. Thus, IL-17A signaling in general, and ACT1 specifically, represent attractive targets for the treatment of psoriasis. We generated Act1 knockout and Act1 L286G knockin (ligase domain) mice to investigate the potential therapeutic effects of targeting ACT1 and its U-box domain, respectively. Act1 knockout, but not Act1 L286G knockin, mice were resistant to increases in CXCL1 plasma levels induced by subcutaneous injection of recombinant IL-17A. Moreover, in a mouse model of psoriasiform dermatitis induced by intradermal IL-23 injection, Act1 knockout, but not Act1 L286G knockin, was protective against increases in ear thickness, keratinocyte hyperproliferation, expression of genes for antimicrobial peptides and chemokines, and infiltration of monocytes and macrophages. Our studies highlight the critical contribution of ACT1 to proinflammatory skin changes mediated by the IL-23/IL-17 signaling axis and illustrate the need for further insight into ACT1 E3 ligase activity.

Abstract
Psoriasis is the most prevalent inflammatory skin disorders, affecting 1-3% of the worldwide population. We previously reported that topical application of methyl 4-(adenin-9-yl)-2-hydroxybutanoate (DZ2002), a reversible S-adenosyl-l-homocysteine hydrolase (SAHH) inhibitor, was a viable treatment in murine psoriatic skin inflammation. In current study, we further explored the mechanisms of DZ2002 on keratinocyte dysfunction and skin infiltration, the key pathogenic events in psoriasis. We conducted genome-wide DNA methylation analysis in skin tissue from imiquimod (IMQ)-induced psoriatic and normal mice, demonstrated that topical administration of DZ2002 directly rectified aberrant DNA methylation pattern in epidermis and dermis of psoriatic skin lesion. Especially, DZ2002 differentially regulated DNA methylation of GATA3 and LCN2 promoters, which maintained keratinocytes differentiation and reduced inflammatory infiltration in psoriatic skin respectively. In vitro studies in TNF-α/IFN-γ-elicited HaCaT manifested that DZ2002 treatment rectified compromised keratinocyte differentiation via GATA3 enhancement and abated chemokine expression by reducing LCN2 production under inflammatory stimulation. Chemotaxis assays conducted on dHL-60 cells confirmed that suppression of LCN2 expression by DZ2002 was accompanied by CXCR1 and CXCR2 downregulation, and contributed to the inhibition of CXCL8-driven neutrophils migration. In conclusion, therapeutic benefits of DZ2002 are achieved through differentially regulating DNA methylation of GATA3 and LCN2 promoters in psoriatic skin lesion, which efficiently interrupt the pathogenic interplay between keratinocytes and infiltrating immune cells, thus maintains epidermal keratinocytes differentiation and prevents dermal immune infiltration in psoriatic skin.

Abstract
There are increasing data about the role of the gut microbiome in various autoimmune diseases, including psoriasis, a chronic inflammatory and immune-mediated disease. Current treatment strategies in psoriasis include immunomodulating biologic agents. A variable response to this type of therapy has been reported in psoriatic patients. A possible effect of biologic therapy on the gut microbiome composition has been suggested, but data are still limited. The aim of this study was to compare the gut microbiome composition between psoriatic patients treated and untreated with biologic drugs in order to identify differences which may highlight the potential impact of the treatment on the gut microbiome. 16S rRNA sequencing and bioinformatic analyses were performed on the fecal samples of 30 psoriatic patients with similar clinicopathological features, 10 of whom were undergoing biologic therapy and 20 not receiving systemic therapy. Alpha and beta diversity significantly differed between the two groups of patients. A reduced bacterial biodiversity in the group of treated patients compared with the group of untreated patients was observed. Differential relative abundances of key gut microbial communities, including Akkermansia muciniphila and Bacteroides plebeius, were identified between the two groups of patients. This study showed that biologic therapy may have an impact on the composition of the gut microbiome of psoriatic patients. Gut microbiome composition could be used as an indicator of response to therapy and the modulation of the microbial composition could help to restore the intestinal symbiosis in psoriatic patients.

Abstract
Background Psoriasis vulgaris is commonly treated with topical corticosteroids and vitamin D analogues. Although potent and super-potent topical corticosteroids are very effective at clearing psoriasis, with short-term reactive treatment durations, symptoms usually recur after treatment discontinuation, necessitating long-term disease management strategies. A foam formulation of calcipotriol and betamethasone dipropionate (Cal/BD foam), consisting of calcipotriol 50 μg/g and betamethasone dipropionate 0.5 mg/g, is approved for the daily treatment of psoriasis for up to 4 weeks. Here, we describe a clinical trial protocol for evaluating the long-term safety and efficacy of twice-weekly Cal/BD foam as a proactive topical maintenance therapy for plaque psoriasis for up to 52 weeks. Objective The aim of this trial was to evaluate the safety and efficacy of Cal/BD foam when applied twice weekly for up to 52 weeks as proactive maintenance therapy, with the goal of preventing or delaying disease relapse as long as possible while minimizing adverse effects. Methods Once-daily Cal/BD foam treatment responders from an initial 4-week open-label period were randomized to receive Cal/BD foam or foam vehicle applied to previously cleared plaques twice weekly for up to 52 weeks. In case of relapse, affected subjects in either group received rescue therapy with once-daily Cal/BD foam for 4 weeks on active areas. Thus, the trial (NCT02899962) compared the long-term use of Cal/BD foam in a proactive approach with a conventional, reactive approach. Planned Outcomes Efficacy endpoints included the time to first relapse, the number of relapse-free days, and the number of relapses during the maintenance phase. Safety assessments included adverse events, incidence of rebound, local safety and tolerability scores, and effects on calcium metabolism and hypothalamic–pituitary–adrenal axis function. Trial registration ClinicalTrials.gov identifier, NCT02899962.

Abstract
Clobetasol propionate (CP), a superpotent topical corticosteroid, holds great promise for psoriasis treatment. However, common side effects like skin atrophy, steroidal acne, hypopigmentation and allergic contact dermatitis associated with it, hamper its utility for topical application. Taking this into consideration, the current work was aimed to fabricate CP loaded cyclodextrin nanosponge (CDNS) based hydrogel, to alleviate the aforementioned side effects, while controlling drug release. Nanosponges were crafted employing β-cyclodextrin (polymer) and diphenyl carbonate (cross linker) and evaluated appropriately. The selected formulation augmented 45 folds water solubility, with respect to pure CP. The formulation possessed entrapment efficiency (56.33 ± 0.94%), particle size (194.27 ± 49.24 nm) with polydispersitive index (0.498 ± 0.095), surface charge (-21.83 ± 0.95 mV) and drug release (86.25 ± 0.28%). Selected CP-CDNS were found crystalline and uniform in size. Further, in vitro cell viability analysis has been performed using THP1 cells to evaluate cytocompatibility of CP nanosponges. The chosen CP nanosponges were then embedded into Carbopol hydrogel, and characterized for rheological behaviour, spreadability, and texture profile. The developed nanoformulations were also assessed in vivo using mouse tail model. Histological and biochemical assessments have been conducted to explore their antipsoriatic activity via oxidative stress biomarkers. The degree of orthokeratosis was observed remarkably (p < 0.001) amplified by CP-CDNS14 hydrogel as compared to untreated group (control) and CP hydrogel. In addition, drug activity and change in epidermal thickness were found significant. Our findings altogether advocated the profound potential of prepared CP nanogel in the topical treatment of psoriasis, with improved patient compliance.

Abstract
Psoriasis is an immune-mediated dermatosis characterized by T-lymphocyte-mediated epidermal hyperplasia, for which there are currently no effective clinical treatments. 'Psoriasis 1' is a Chinese herbal medicine formulation that has been recently used extensively in China for treating patients with psoriasis. However, the molecular mechanism of action of this potent formulation has not yet been fully elucidated. In the present study, the effects of 'Psoriasis 1' on T ymphocytes in patients with psoriasis were investigated and the underlying molecular mechanism was discussed. Blood samples were collected from 40 patients with psoriasis. ELISA was employed to assess the levels of tumour necrosis factor-α, interferon-γ, interleukin (IL)-2, IL-6, transforming growth factor-β, IL-4, IL-12, IL-23 and vitamin D (VD). Western blot and quantitative PCR analyses were used to investigate the expression levels of VD receptor (VDR) and signal transducer and activator of transcription (STAT)4 in T lymphocytes. 'Psoriasis 1' was observed to significantly increase CD4+ T cells. It also notably upregulated the mRNA and protein expression of VDR, and downregulated the mRNA and protein expression of STAT4. Moreover, the suppression of VDR was found to aggravate the inflammatory response, which was reversed by 'Psoriasis 1.' Thus, this formulation reportedly decreased the inflammation mediated by T lymphocytes in patients with psoriasis through inhibiting VDR-mediated STAT4 inactivation.

The relevance of pathophysiological alterations in redox signaling of 4-hydroxynonenal for pharmacological therapies of major stress-associated diseases. Free Radic Biol Med 2020; 157:128-153. [PMID: 31756524 DOI: 10.1016/j.freeradbiomed.2019.11.023] [Citation(s) in RCA: 62] [Impact Index Per Article: 15.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/30/2019] [Revised: 11/04/2019] [Accepted: 11/17/2019] [Indexed: 02/07/2023]
Abstract
Modern analytical methods combined with the modern concepts of redox signaling revealed 4-hydroxy-2-nonenal (4-HNE) as particular growth regulating factor involved in redox signaling under physiological and pathophysiological circumstances. In this review current knowledge of the relevance of 4-HNE as "the second messenger of reactive oxygen species" (ROS) in redox signaling of representative major stress-associated diseases is briefly summarized. The findings presented allow for 4-HNE to be considered not only as second messenger of ROS, but also as one of fundamental factors of the stress- and age-associated diseases. While standard, even modern concepts of molecular medicine and respective therapies in majority of these diseases target mostly the disease-specific symptoms. 4-HNE, especially its protein adducts, might appear to be the bioactive markers that would allow better monitoring of specific pathophysiological processes reflecting their complexity. Eventually that could help development of advanced integrative medicine approach for patients and the diseases they suffer from on the personalized basis implementing biomedical remedies that would optimize beneficial effects of ROS and 4-HNE to prevent the onset and progression of the illness, perhaps even providing the real cure.

Abstract
Introduction: Treatment adherence continues to be a major challenge in psoriasis. Patient preference studies, especially discrete-choice experiments, are gaining popularity to gather insights into patient reported treatment outcomes. This systematic literature review aimed to critically assess all discrete choice experiments exploring patients' and physicians' preferences for psoriasis treatment characteristics.Methods: PubMed and EMBASE databases were searched using keywords "psoriasis" and "preferences" to identify relevant literature. Discrete-choice experiments conducted in French or English from the year 2000 onwards, that focused on evaluating psoriasis treatment preferences in patients and/or physicians, were included. The relative importance of treatment attributes was assessed and studies were critically appraised using validated checklists.Results: Out of 987 articles identified, 25 articles fulfilled the inclusion criteria. Overall, patients and physicians prioritize efficacy-specific outcomes. Patients are shown to place greater importance to process attributes when compared to physicians, especially route and location of administration. Physicians focus primarily of efficacy attributes, however when the top two attributes are considered, safety outcomes increasingly become considered important. Of the studies, 60% conducted subgroup analysis, of which many reported associations between specific patient characteristics and preferences. Factors such as age, disease severity, and duration of condition significantly affected preferences for treatment attributes.Conclusions: This review provides insight into the types of attributes that patients and physicians value most, and therefore can help improve shared decision-making. The findings of this study also encourage regulatory agencies to continue integrating patient preferences in their decision-making.

Abstract
Psoriasis is a common cutaneous disease that has major implications in the quality of life of the patient. It is characterised by a chronic course and in some subtypes, it can be life threatening. Many studies have focused on the pathogenesis concerning this disease therefore improving the therapeutic approaches. Phototherapy represents a well-known treatment option for psoriasis. The depletion of T cells mostly from the epidermis, after exposure to phototherapy, validates the role of this treatment. The 308 nm excimer laser has the ability to treat mild, moderate and even severe but localised psoriasis plaques and plays an important role in the treatment management of psoriasis. In this report, we present the case of a patient diagnosed with plaque psoriasis, resistant to topical ointments, successfully treated with the 308 nm excimer laser. Although further studies are still required to consider the 308 nm excimer laser as a first line therapy, its high response rates have significantly influenced the therapeutic approach in psoriasis.

Abstract
BACKGROUND There is a lack of any overview of changes over time and variation in the epidemiology of psoriasis with age and between genders. OBJECTIVES To perform a systematic review of published population-based studies on variations in psoriasis incidence and prevalence with age and between genders, and to explore trends in psoriasis epidemiology over time. METHODS Eleven electronic and regional databases were searched from their inception dates to October 2019. No language restrictions were applied. Studies were eligible if they reported on changes in psoriasis incidence and/or prevalence over time and/or by age group and gender. RESULTS In total 308 papers were critically appraised, from which 90 studies from 22 countries were included. Incidence data confirmed a clear bimodal age pattern in psoriasis onset, with the first and second peaks at around 30-39 and 60-69 years of age, respectively, and evidence suggesting that it presents slightly earlier in women than in men. Prevalence data showed an increasing trend with age until around 60 or 70 years, after which it decreases. Although there was lack of agreement on specific gender differences in psoriasis incidence and prevalence, a slight male predominance was reported in several studies. Studies worldwide suggested a stable or slightly decreasing trend in psoriasis incidence, while an increasing trend in psoriasis prevalence has been consistently reported. One particular challenge faced was the vastly different methodologies used in the included studies, which contributed to some of the heterogeneity of the results. CONCLUSIONS Studies on changes over time in the occurrence of psoriasis have contributed to a greater appreciation of the increasing burden of the disease. However, further research is required to determine the reasons driving the increase in psoriasis prevalence over time.

Abstract
Background:
Psoriasis is an autoimmune disease that ingeminates itself with the repeated
proliferation of keratinocytes. It globally strikes a 2-5 % population on an average. Management
of psoriasis remains a daunting task with various challenges influencing treatment, such as patient
conformity and adherence to therapy, delicate patient profiles, psychological aspects, and skin as a
barrier to topical delivery. The first part reviewed pathophysiology, triggering factors, and clinical
classification. The second part reviewed all the therapies, such as topical, oral, biological, parenteral
therapy, phototherapy, and the phyto-pharmaceuticals.
Methods:
The research data related to the existing and upcoming therapies for psoriasis treatment,
several nanocarriers, existing marketed formulations, and detailed description of phytopharmaceuticals
with their mechanism.
Results:
Topical therapy is the mainstay treatment option with limited adverse effects. Biological therapy
has reformed conventional psoriasis treatment by being more efficacious and has increased patient
acceptance due to decreased adverse events. Nanoformulations present an edge over conventional
therapy due to improved anti-psoriatic effect and decreased side effects. Phyto-pharmaceuticals act as
a complementary and alternative therapy for diminishing psoriasis symptoms.
Conclusion:
A rationalized cost-effective patient compliant therapy is required for effective management
and complete cure of psoriasis.

Abstract
BACKGROUND Currently the leading cause of global disability, clinical depression is a heterogeneous condition characterised by low mood, anhedonia and cognitive impairments. Its growing incidence among young people, often co-occurring with self-harm, is of particular concern. We recently reported very high rates of depression among first year university students in Northern Ireland, with over 25% meeting the clinical criteria, based on DSM IV. However, the causes of depression in such groups remain unclear, and diagnosis is hampered by a lack of biological markers. The aim of this exploratory study was to examine DNA methylation patterns in saliva samples from individuals with a history of depression and matched healthy controls. RESULTS From our student subjects who showed evidence of a total lifetime major depressive event (MDE, n = 186) we identified a small but distinct subgroup (n = 30) with higher risk scores on the basis of co-occurrence of self-harm and attempted suicide. Factors conferring elevated risk included being female or non-heterosexual, and intrinsic factors such as emotional suppression and impulsiveness. Saliva samples were collected and a closely matched set of high-risk cases (n = 16) and healthy controls (n = 16) similar in age, gender and smoking status were compared. These showed substantial differences in DNA methylation marks across the genome, specifically in the late cornified envelope (LCE) gene cluster. Gene ontology analysis showed highly significant enrichment for immune response, and in particular genes associated with the inflammatory skin condition psoriasis, which we confirmed using a second bioinformatics approach. We then verified methylation gains at the LCE gene cluster at the epidermal differentiation complex and at MIR4520A/B in our cases in the laboratory, using pyrosequencing. Additionally, we found loss of methylation at the PSORSC13 locus on chromosome 6 by array and pyrosequencing, validating recent findings in brain tissue from people who had died by suicide. Finally, we could show that similar changes in immune gene methylation preceded the onset of depression in an independent cohort of adolescent females. CONCLUSIONS Our data suggests an immune component to the aetiology of depression in at least a small subgroup of cases, consistent with the accumulating evidence supporting a relationship between inflammation and depression. Additionally, DNA methylation changes at key loci, detected in saliva, may represent a valuable tool for identifying at-risk subjects.

Abstract
BACKGROUND Few existing studies on the global incidence, prevalence, and burden of disease from psoriasis are of high quality, making reliable data and comparisons difficult to find. METHODS We analyzed global psoriasis trends from 1990 to 2017 in 195 countries worldwide through the Global Burden of Disease Study database, including age-standardized prevalence rates, percent change in age-standardized prevalence rates, age and sex patterns, and psoriasis burden using disability-adjusted life years. RESULTS The age-specific prevalence rate in 2017 showed a left-skewed distribution with a peak between 60 and 70 years of age and a roughly equal male-to-female ratio across all ages. Psoriasis burden was greatest in countries with high income and high sociodemographic index. A positive linear relationship between psoriasis prevalence and comorbidities is seen with cardiovascular disease (R = .67), mental health (R = .63), type 2 diabetes mellitus (R = .55), stroke (R = .51), non-Hodgkin lymphoma (R = .84), Hodgkin lymphoma (R = .77), nonmelanoma skin cancer (R = .68), and inflammatory bowel disease (R = .55) across all countries in 2017. CONCLUSION There is increasing prevalence, burden, and associated comorbidities of psoriasis on a global scale and the need for support to reduce this important global health disparity.

Abstract
Leprosy presents with erythematous or pigmented patches, plaques, and nodules with loss of sensation and nerve thickening. Psoriasis presents as sharply demarcated erythematous plaques with overlying silvery scales. The controversial relationship between both has existed since biblical times when psoriasis was considered to be a form of leprosy. Records of leprosy patients have depicted a rarity of the coexistence of psoriasis, leading to a hypothesis that both rarely develop in the same patient. We report a rare coexistence of both diseases.

Abstract
Psoriasis is a common non-communicable chronic immune-mediated skin disease, affecting approximately 125 million people in the world. Its pathogenesis results from a combination of genetic and environmental factors. The pathogenesis of psoriasis seems to be driven by the interaction between innate immune cells, adaptive immune cells and keratinocytes, in a process mediated by cytokines (including interleukins (IL)-6, IL-17 and IL-22, interferon and tumor necrosis factor) and other signaling molecules. This leads to an inflammatory process with increased proliferation of epidermal cells, neo-angiogenesis and infiltration of dendritic cells in the skin. Dysfunctional de novo glucocorticoid synthesis in psoriatic keratinocytes and the skin microbiome have also been suggested as mediators in the pathogenesis of this disease. To understand psoriasis, it is essential to comprehend the processes underlying the skin immunity and neuroendocrinology. This review paper focuses on the skin as a neuroendocrine organ and summarizes what is known about the skin immune system, the brain-skin connection and the role played by the serotonergic system in skin. Subsequently, the alterations of neuroimmune processes and of the serotonergic system in psoriatic skin are discussed, as well as, briefly, the genetic basis of psoriasis.

Abstract
Introduction: Ixekizumab (an IL-17A antagonist) is a biologic therapeutic licensed for use in moderate-to-severe plaque psoriasis and psoriatic arthritis. IL-17 antagonists (also including Secukinumab and Brodalumab) represent a new generation of biologic therapy with rapid and high response rates, quickly becoming a crucial part of the psoriasis treatment armamentarium.Areas covered: In this review, we describe how IL-17A antagonists disrupt inflammatory cascades in psoriasis and summarize results from clinical trials examining the safety and efficacy of ixekizumab against placebo and comparators.Expert opinion: Ixekizumab induces a 75% reduction in psoriasis area severity index (PASI 75) in 89% of patients after 12 weeks and after 1 year, PASI 75 is maintained in 80% of patients. Ixekizumab is superior to both etanercept and ustekinumab, however, further comparator trials are needed to determine superiority between newer agents. Network meta-analysis suggests that ixekizumab is one of the most rapid and efficacious agents for treating psoriasis, but ideally more long-term real-world data are needed to determine the persistence of response. Candida may be commonly encountered during treatment and IL-17 agents should be avoided in patients with inflammatory bowel disease. Overall, ixekizumab represents an efficacious and well-studied therapeutic that can offer biologic-naïve and bio-failure patients durable disease control.

Abstract
This study examined the association between digoxin use and subsequent psoriasis risk using a population-based database in Taiwan. This cohort study enrolled 15 545 digoxin users and 15 545 propensity score-matched non-users from the Taiwan National Health Insurance Research Database. Each patient was independently followed up for 5 years to confirm whether they had been diagnosed with psoriasis. Cox proportional hazard regression was used to estimate psoriasis risk among digoxin users. Subgroup and sensitivity analyses were also performed. The psoriasis incidence rates were 3.02 and 2.27 per 1000 person-years among digoxin users and non-users, respectively. After adjustment for confounders, psoriasis risk was significantly higher among digoxin users than among non-users. Notably, in most subgroup analyses, digoxin use tended to increase psoriasis risk, particularly among patients with heart failure, diabetes, hypertension and hyperlipidaemia. Moreover, significantly increased psoriasis risk was noted over 2, 3, 4 and 5 years of digoxin use. In conclusion, our findings confirm that digoxin use increases subsequent psoriasis risk. Thus, physicians should be aware of this association and accordingly estimate the risks and benefits of digoxin use. Nevertheless, some patient variables, such as body mass index and obesity, were unavailable in this study. The findings in this study should be elucidated carefully because the potential effects of these factors could not be considered.

Abstract
Chronic inflammatory diseases (CID) share many common features, such as debilitating illness, increased mortality, impaired quality of life and productivity, and high economic burden. The approach to treating CID has shifted over the last 20 years from symptom to mechanism of action-targeted therapy following the development of primarily biologic drugs, in which the same therapy can potentially treat multiple diseases. Developing these drugs requires novel strategies and a multidisciplinary approach for implementation. This article provides an overview of shared features for CID clinical trials and addressing common challenges in their planning and execution. Since CID studies often test the same drug for treating different pathologies, knowledge of the drug from previously investigated therapeutic indications can be leveraged when planning clinical trials. Given the variety of CID signs and symptoms, eligibility criteria need to clearly define the target patient population by minimising ambiguity and risk of misunderstanding. Other common challenges include an elevated response in the placebo arm, the subjectivity of investigator assessments, and the use of appropriate patient-reported outcomes. Several measures can help minimise the impact of the aforementioned issues on study outcome, including centralised eligibility review and endpoint adjudication, tight control of background therapy and concomitant medications, and intensive training of assessors. The above common features support an approach to CID as a largely interconnected therapeutic area in which a multidisciplinary approach, application of common strategies, and lessons learnt across different indications represent crucial factors for effectively planning and executing clinical trials.

Loss of the Epigenetic Mark 5-hmC in Psoriasis: Implications for Epidermal Stem Cell Dysregulation. J Invest Dermatol 2019; 140:1266-1275.e3. [PMID: 31837302 DOI: 10.1016/j.jid.2019.10.016] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2019] [Revised: 10/22/2019] [Accepted: 10/28/2019] [Indexed: 12/22/2022]
Abstract
Epigenetic regulation has a profound influence on stem cell fate during normal development in maintenance of physiologic tissue homeostasis. Here we report diminished ten-eleven translocation (TET) methylcytosine dioxygenase expression and loss of the DNA hydroxymethylation mark 5-hydroxymethylcytosine (5-hmC) in keratinocyte stem cells and transit amplifying cells in human psoriasis and in imiquimod-induced murine psoriasis. Loss of 5-hmC was associated with dysregulated keratinocyte stem cell kinetics, resulting in accumulation of nestin and FABP5-expressing transit amplifying cells to produce classic psoriatic epidermal architecture. Moreover, 5-hmC loss was accompanied by diminished TET1 and TET2 mRNA expression. Genome-wide mapping of epidermal 5-hmC in murine psoriasis revealed loci-specific loss of 5-hmC in genes regulating stem cell homeostasis, including MBD1, RTN1, STRN4, PRKD2, AKT1, and MAPKAP2, as well as those associated with RAR and Wnt/β-catenin signaling pathways. In vitro restoration of TET expression by ascorbic acid was accomplished in cultured human keratinocyte stem cells to show similar Ca++-induced differentiation, resulting in increased 5-hmC levels and reduced nestin expression. To our knowledge, an epigenetic deficiency in psoriasis with relevance to stem cell dysregulation has not been previously reported. This observation raises the possibility that epigenetic modifiers that impact on the TET-5-hmC pathway may be a relevant approach of heretofore unappreciated therapeutic utility.

Psoriatic and psoriatic arthritis patients with and without jet-lag: does it matter for disease severity scores? Insights and implications from a pilot, prospective study. Chronobiol Int 2019; 36:1733-1740. [PMID: 31645138 PMCID: PMC6832868 DOI: 10.1080/07420528.2019.1678629] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2019] [Accepted: 10/04/2019] [Indexed: 12/13/2022]
Abstract
Background: Jet-lag may affect air-travelers crossing at least two time-zones and has several health-care implications. It occurs when the human biological rhythms are out of synch with respect to the day-night cycle at the country destination. Its effect in psoriasis is missing. We aimed to evaluate the effect of Jet-lag in psoriatic patients' management. Methods: This is a prospective observational study that enrolled psoriatic patients that underwent a flight: patients who experienced jet-lag were compared to patients who did not experience jet-lag. Before the flight, a dermatologist recorded clinical and demographical data with particular attention to Psoriasis Area Severity Index (PASI) and Disease Activity in Psoriatic Arthritis (DAPSA). Patients performed Self-Administered Psoriasis Area Severity Index (SAPASI), the Dermatology Life Quality Index (DLQI) and the pruritus Visual Analog Scale (VAS) scores. After the flight, patients completed the SAPASI, DLQI and pruritus-VAS scores. Results: The sample recruited comprised of 70 psoriatic patients aged 42.4 ± 9.7 years (median 42.5 years). Thirty (42.9%) were males, mean BMI was 25.5 ± 2.2 kg/m2. Average disease duration was 15.2 ± 7.1 years, and 20 (28.6%) subjects had developed PsA. Average hours of flight were 5.4 ± 3.5 (median 3.5 h), with 34 (48.6%) subjects reporting jet-lag. At the multivariate regression analysis, the change in the SAPASI score resulted correlated with jet-lag (regression coefficient 1.63, p = .0092), as well the change in the DLQI score (regression coefficient = 1.73, p = .0009), but no change on the pruritus VAS scale was found. Conclusions: The present study suggests that jet-lag may influence disease severity and DLQI scores, but not itch in psoriatic patients.

Abstract
Psoriasis is a common chronic inflammatory skin disease which affects 0.5-1 % of children and 2-3 % of the adult population. In Croatia, 1.6 % of the population suffer from psoriasis. Distribution of the disease is bimodal, with the first peak at the age of 20-30, and the second at the age of 50-60. The etiopathogenesis of the disease is multifactorial, the key factors being genetic predisposition combined with immunological disorders, environmental factors and skin barrier damage. There are several clinical variants of the disease. The main signalling pathways in psoriasis include TNF-α, IL-23 and IL-17. Topical agents are used for the treatment of the mild form, and the systemic conventional therapy is used for the treatment of moderate to severe forms of the disease. In cases where's no response, or intolerance or contraindications are present, new targeted medications are to be administered. Development in the field of immunogenetics of psoriasis leads to personalized medicine.

Abstract
Psoriasis is an autoimmune skin disease which characteristic of a well-demarcated, erythematous, raised lesion with silvery-white dry scale. Although the mechanism of psoriasis has not been fully understood so far, much progress has been made in understanding many of its complex potential mechanism, particularly the crucial role of the IL-23/Th17 axis. There are a large number of psoriasis models that reflect the complexity of the psoriasis mechanisms. In this review, we summarize various psoriasis mouse models, detail the features and molecular mechanisms of these mouse models, and discuss their strengths and limitations for psoriasis research. The development of mouse models of psoriasis provide an important basis for studying psoriasis pathogenesis and antipsoriatic drugs development. Therefore, the application of various psoriasis mouse models in antipsoriatic drug development are also discussed.

Abstract
Psoriasis is a chronic inflammatory skin disorder mediated by the T-cell–related immune response. Psoriatic patients may have a variety of comorbidities, but their risk of end-stage renal disease (ESRD), particularly according to the subtype of psoriasis, is unclear. We investigated the risk of ESRD in patients with psoriasis according to the subtype of psoriasis and history of systemic therapy for psoriasis. A total of 2,121,228 adults (1,590,921 in the control group and 530,307 in the psoriasis group) were enrolled in this nationwide population-based cohort study until 2015. During follow-up, 1,434 of the subjects in the psoriasis group developed ESRD. After adjusting for confounding factors, psoriasis was associated with the risk of ESRD (hazard ratio (HR) 1.58, 95% confidence interval [95% CI] 1.47–1.68). The psoriatic arthritis group (HR 7.60, 95% CI 1.90–30.41) had a higher risk of ESRD than the control group. Interestingly, no such association was detected in the systemically treated group (HR 1.07, 95% CI 0.80–1.41). Moreover, the acitretin-treated group had a lower risk of ESRD (HR 0.658, 95% CI, 0.494–0.875) than the non-systemically treated group. In conclusion, the risk of developing ESRD in patients with psoriasis differed according to the type of treatment and the presence of arthritis.

Abstract
Nanodermatology is an emerging, multidisciplinary science, arising from the convergence of nanotechnology, pharmacology, physics/biophysics, chemistry/biochemistry, chemical engineering, material science, and clinical medicine. Nanodermatology deals with (a) skin biology, anatomy, and physiology at the nanoscale ("skin nanobiology"), (b) diagnosis performed by means of novel diagnostic devices, assisted by nanobiotechnologies ("nanodiagnosis"), and (c) treatment through innovative therapeutic agents, including phototherapy ("photonanotherapy"/"photonanodermatology") and systemic/topical drug administration ("nanotherapy") at the nanoscale, and drug delivery-such as transdermal or dermal drug delivery (TDDD/DDD)-enhanced and improved by nanostructures and nanodrugs ("nanodrug delivery"). Nanodermatology, as a super-specialized branch of dermatology, is a quite recent specialty: the "Nanodermatology Society" founded by the eminent dermatologist Dr. Adnan Nasir, was established in 2010, with the aim of bringing together different stakeholders, including dermatologists, nanotechnology scientists, policy-makers and regulators, as well as students and medical residents. Psoriasis has a prevalence of 2-3% worldwide and imposes a severe clinical and societal burden. Nanodermatology-based solutions appear promising for the proper treatment and management of psoriasis, assisting and enhancing different steps of the process of health-care delivery: from the diagnosis to the therapeutics, paving the way for a personalized approach, based on the specific dysregulated biomarkers.

Abstract
OBJECTIVE Although several scores exist to assess psoriasis severity, most have marked limitations that rule out their use in routine clinical practice. A new score, the Simplified Psoriasis Index (SPI), has recently been developed and validated in adults in Britain for such use. It has separate components for current severity (SPI-s), psychosocial impact (SPI-p) and past history and interventions (SPI-p), and it is suitable for either professional assessment or patient self-assessment. The aim of this work was to produce a validated translation of SPI into French (as spoken in France). METHODS The index was translated and validated using a strict methodology comprising respectively five and eight phases for the professional (proSPI) and self-administered instruments (saSPI). Translation of the saSPI instrument also involved a cognitive debriefing with five psoriasis patients. RESULTS Linguistic discrepancies and subtle differences of meaning arising during the process were closely examined. The developer of the instrument ensured conceptual accuracy. A panel of health experts guaranteed that medical terms were correctly translated. Five patients with plaque psoriasis (two female and three male of median age 45 years [range: 31-78]) tested the SPI-p version during cognitive interviews and found the questionnaire clear and easy to understand. CONCLUSION Validated French translations of both SPI instruments are now available for use in routine clinical practice. Further investigations are currently underway to validate the psychometric properties of the instrument.

Abstract
OBJECTIVES Interleukin(IL)-23 is a key cytokine in the pathogenesis of psoriasis, this meta-analysis was to analyze the efficacy and safety of IL-23p19 blockers in patients with plaque psoriasis. METHODS A systematic review of the literature was performed to collect double-blind randomized controlled trials(RCTs). The pooled relative risk(RR) with 95% confidence interval(CI) was calculated. All analyses were conducted with intention-to-treat basis. RESULTS A total of 13 studies contained 5155 plaque psoriasis patients were included in our meta-analysis. The results indicated that IL-23p19 blockers had better efficacy than placebo for Psoriasis Area Severity Index score reductions from baseline of 75% or more (PASI75) (RR = 11.47, P < 0.001) and static Physician's Global Assessment score of 0 or 1(sPGA0/1) (RR = 11.32, P < 0.001). IL-23p19 blockers have similar safety with placebo about the incidence of adverse events(AEs) (RR = 1.22, P = 0.096) and serious adverse events(SAEs) (RR = 2.93, P = 0.965), but IL-23p19 blockers carried an increased incidence rate of infections (RR = 1.39, P < 0.001). While compared with adalimumab and ustekinumab, IL-23p19 blockers were more effective and had the similar tolerance. Among three IL-23p19 blockers, guselkumab was the most efficacious treatments, and risankizumab was better tolerated than the others. CONCLUSION The IL-23p19 blockers have excellent efficacy and great safety in plaque psoriasis patients, but long-term safety remains to be determined.

Abstract
AIM Until recently, clinicians caring for patients with psoriasis who were infected with hepatitis C virus (HCV) were concerned that treating one condition could exacerbate the other. We evaluated the outcome of treatment with direct-acting antiviral agents (DAAs) on patients with psoriasis having chronic hepatitis C (CHC) infection. PATIENTS AND METHODS This was an observational prospective cross-sectional study. It included CHC-naive patients with plaque psoriasis. All patients received sofosbuvir plus daclatasvir once daily for 12 weeks for treatment of CHC. Psoriasis area severity index (PASI) scores and the dermatology quality-of-life index were evaluated at the start of treatment with DAAs and then at 12 and 24 weeks after the end of HCV treatment. The primary end point was sustained virological response 12 weeks after treatment (SVR12). RESULTS A total of 34 CHC-naive patients were enrolled in this study. Most of them were of male sex (76.5%), and most of them had severe psoriasis, as the mean PASI score was 32. The primary and secondary end points (SVR12 and SVR24) for our patients were 100%. Regarding PASI and dermatology quality-of-life index scores, there was a highly significant difference before start of treatment and after treatment at 12 and 24 weeks. The most common adverse events are fatigue and headache. CONCLUSION Sofosbuvir plus daclatasvir is effective in the eradication of HCV and improvement of symptoms in patients with psoriasis having CHC infection. Future large series studies are needed to evaluate this promising effect of DAAs.

Abstract
INTRODUCTION Psoriasis is a chronic inflammatory skin disease which could lead to serious complications and increased risk of cardiovascular diseases. Psoriasis was recognised as a serious non-communicable disease with important public health impact by member states in the World Health Assembly resolution in 2014. However, data on psoriasis epidemiology are scarce worldwide, especially from low-income and middle-income countries. Only a few epidemiological studies on psoriasis have been conducted in parts of China, mostly without appropriate sampling design and data analysis. AIM This study aims to obtain the prevalence of psoriasis in China and relevant risk factors through a nationwide, population-based study with adequate statistical design. METHODS AND ANALYSIS This is a cross-sectional study to be conducted in 60 sites across China. A multistage, cluster random sampling design is used. Participants should have local household registration or be residing in the survey area for at least 6 months during the past year. The presence of psoriasis is ascertained independently by two certified dermatologists. If any discrepancies in the diagnosis occur, consensus will be met via discussion. All participants will be interviewed with a questionnaire to collect sociodemographic and disease information. The field survey will be implemented from October 2018 to June 2019. All statistical analyses will be conducted using survey procedures in SAS V.9.2 software to adjust for the complex sample design. ETHICS AND DISSEMINATION The study has been reviewed and approved by the ethics committee of the Institute of Dermatology, Chinese Academy of Medical Sciences and Peking Union Medical College (Nanjing, China). A written informed consent will be obtained from all participants before the questionnaire survey. Findings of the study will be disseminated through publications in peer-reviewed journals.

Abstract
Background: Tildrakizumab is a high-affinity, humanized, IgG1 κ, anti-interleukin-23 monoclonal antibody approved for moderate-to-severe plaque psoriasis.Objectives: This analysis examined whether tildrakizumab's week-28 efficacy can be sustained or improved to week 52.Methods: Psoriasis patients on the same-dose tildrakizumab (100 or 200 mg) in the first 52 weeks achieving week-28 PASI ≥50 were pooled from two phase-3 randomized controlled trials, and grouped into four mutually exclusive week-28 PASI response groups. Patients' week-52 PASI responses were compared to their week-28 PASI responses.Results: Of 352 patients receiving 100-mg tildrakizumab, 10.5%, 25.3%, 38.4%, and 25.9% achieved PASI 50-74, 75-89, 90-99, and 100 at week 28, respectively. Among patients achieving PASI ≥90, ≥75, or ≥50 at week 28, 89.4%, 91.1%, or 97.4% maintained their week-28 PASI responses at week 52, respectively. Among patients achieving PASI 50-74, 75-89, or 90-99 at week 28, 64.8%, 33.7%, or 25.2% improved their week-28 PASI responses at week 52, respectively.Limitations: This post hoc analysis may be less robust than an a priori analysis.Conclusions: Most tildrakizumab-treated patients with week-28 PASI ≥75 maintained their week-28 PASI improvement at week 52. More than half of week-28 partial responders (PASI 50-74) improved their PASI responses to PASI ≥75 at week 52. Clinicaltrials.gov identifiers: NCT01722331, NCT01729754.

Abstract
Psoriasis is a chronic, immune-mediated, inflammatory, and debilitating skin disease with significant impact on patients’ quality of life. Its pathogenesis is complex and not yet fully understood. However, the IL-23/IL-17 axis is currently considered the main pathogenic pathway in psoriasis. Guselkumab is a fully human immunoglobulin G1 λ (IgG1λ) monoclonal antibody (mAb) that binds to the p19 subunit of IL-23. It is the first of its class, already approved by the US Food and Drug Administration (FDA), as well as the European Medicines Agency (EMA) for the treatment of adult patients with moderate-to-severe plaque psoriasis who are candidates for either systemic therapy or phototherapy. Several clinical trials have demonstrated potential benefits of guselkumab over other already approved immunomodulators in terms of safety and efficacy. The results of the head-to-head trial ECLIPSE were recently released and are addressed in this review. They contribute to the increasing confidence in guselkumab, demonstrating great potential for long-term treatment of psoriasis. However, further long-term data and additional comparative studies will be essential for positioning guselkumab in the therapeutic armamentarium for psoriasis.

Abstract
The aim of this study is to evaluate ovarian reserve in women with psoriasis. Thirty-six women with psoriasis and 36 healthy women were enrolled in this prospective study. On day 3 of the menstrual cycle, blood samples for AMH and other hormones were collected. On the same day, antral follicle count (AFC), and ovarian volumes were measured. A multiple regression analysis was carried out to examine the contribution of factors to the serum AMH levels in patients with psoriasis. The serum AMH levels and ovarian volumes were lower in the psoriasis group than in the control group (1.85 ± 1.13 ng/ml vs 2.46 ± 1.21 ng/ml, p = .029 and 10.43 ± 3.08 cm3 vs 11.93 ± 3.01 cm3, p = .038). However, the mean AFC between the two groups was not significantly different. The psoriasis area severity index (PASI) score did not correlate with AMH. On the other hand, the duration of the disease negatively correlated with AMH, total AFC and ovarian volume. In the multiple regression analysis, duration of disease and total AFC were the most significant contributors to the serum AMH levels in patients with psoriasis. Autoimmune diseases may affect ovarian reserve regardless of immunosuppresive treatment. Longitudinal follow-ups regarding reproductive function might be required in women with psoriasis.

Abstract
Psoriasis is a chronic autoimmune disease affecting skin which may also manifest in nails and joints. Several biologic treatments have been approved in Japan for psoriasis. Each biologic has a different profile for efficacy and safety, including different dosing regimens and co‐payment considerations which may complicate treatment decisions made by patients and physicians during short consultations. Elucidating patient preference is expected to contribute to shared decision‐making between patients and physicians to optimize treatment satisfaction and outcomes. However, the number of studies investigating this in Japan is very limited. The study used a discrete choice experiment methodology to elicit patient preferences for hypothetical options in an experimental framework. Participants were asked to choose their preferred treatment option from two hypothetical choices, defined by different levels of six attributes (i.e. early onset of efficacy, long‐term efficacy, sustained efficacy after drug withdrawal, dosing convenience, co‐payment and risk of serious infection). The survey included 16 treatment choice scenarios and was completed by 395 participants. Across all participants, the attribute regarded as most important was sustained efficacy after drug withdrawal, followed by dosing convenience, co‐payment, long‐term efficacy, early onset of efficacy and risk of serious infection. The study found that patients prefer treatments which have durable efficacy and lower treatment burden characterized as fewer injection frequency and lower co‐payment. These results may be helpful to understand patient preference for biologic treatments used for psoriasis in Japan and contribute to shared decision‐making between patients and physicians to improve patient satisfaction and treatment outcomes.

Abstract
Psoriasis (PS) is a systemic, immune-mediated inflammatory disorder. However, the whole lymphocyte compartment and the potential pathologies of PS have not been fully characterized. In the present study, we examined whole lymphocyte subsets and signal transduction proteins using high-dimensional single-cell mass cytometry and a bioinformatics pipeline for an in-depth characterization of the immune cell subsets and protein profiles involved in pathways in the peripheral blood of patients with PS. We identified 15 major immune cell populations in T cell lineages and characterized various CD3+CD4+ Th and CD3+CD8+ T cytotoxic cell populations simultaneously across 24 leukocyte markers and 7 proteins related to the signal transduction pathways. High-dimensional analysis identified 3 new subsets that are abundant in PS peripheral blood, resembling CD3-CD4+ lymphoid tissue inducer cells, Tc17 cells, and CD8+CXCR3+ Tregs. We confirmed the CD3-CD4+ cells, and their features and functions, in an independent PS cohort. The use of single-cell mass cytometry allows systemic-level characterization of lymphocyte subpopulations and dysregulated signaling pathways in the blood of patients with PS, identifying abnormalities of different immune cell subsets. We validated that the CD3-CD4+ cells had elevated OX40 and decreased FRA2 expression, which were positively associated with the PS area and severity index.

Abstract
Psoriasis is an inflammatory skin disease with preference for the skin and joints that occurs due to hyper-proliferation and abnormal apoptosis of keratinocytes. DUSP1 expression in dermal mesenchymal stem cells (MSCs) is obviously lower in psoriasis patients than that in healthy individuals. The present study aimed to explore the roles of DUSP1 in the proliferation and apoptosis of HaCaT cells treated with a cocktail of M5. We showed that DUSP1 was markedly reduced in psoriasis patients and M5-treated HaCaT cells compared with the control subjects. MTT and BrdU assays revealed that overexpression of DUSP1 significantly suppressed the proliferation of HaCaT cells. Furthermore, DUSP1 decreased M5-induced the upregulation of cyclin D1 and Rb. In addition, we demonstrated that forced overexpression of DUSP1 caused an augment of cell apoptosis rate, c-caspase 3 protein level and the Bax/Bcl-2 ratio. Finally, we determined that enhancing DUSP1 expression resulted in the reduction of p-ERK, p-Elk-1 and Egr-1 protein levels using western blot, and the Chromatin immunoprecipitation (ChIP) assay displayed that p-Elk-1 binds to the promoter of Egr-1 in HaCaT cells. The roles of DUSP1 in cell proliferation and apoptosis were abolished by overexpression of Egr-1. In summary, gain function of DUSP1 regulates proliferation and apoptosis of HaCaT cells through the ERK/Elk-1/Egr-1 signaling pathway.

Abstract
BACKGROUND Psoriasis is a chronic, relapsing disease and most epidemiological studies include selected patients undergoing systemic therapies only. Epidemiological data suggest that psoriasis affects 2-3% of the general population, and that men and women are equally affected. The objective was to identify differences in gender for disease severity, patient characteristics and comorbidities in patients with moderate to severe psoriasis, independent of therapy. METHODS A retrospective medical chart review of consecutive patients diagnosed with moderate-severe psoriasis at a single center between 2004 and 2017, with a complete set of medical records, was undertaken. Both univariate and multivariate regression analyses were performed. Statistical significance was defined as P<0.05. RESULTS The male-to-female ratio revealed a higher prevalence for male gender (2:1, P<0.05). Whilst no significant differences were found for most factors according to gender, age at first evaluation was significantly higher for women. Logistic regression analysis indicated that autoimmune/autoinflammatory diseases were more frequently observed in women, as well as phenotypes other than plaque psoriasis and hypertension. Inversely, dyslipidemia was more frequently associated with male gender. CONCLUSIONS Our results show that moderate-severe psoriasis is more common in men and suggests a differential gender distribution of some specific comorbidities in the setting of this disease.

Abstract
Psoriasis is a chronic inflammatory disease with complex etiology involving multiple factors. Current treatment methods are highly limited and there is a strong need for the development of safer and efficacious agents. We have previously shown that a water-soluble extract derived from hardy kiwifruit Actinidia arguta, called PG102, shows potent anti-inflammatory effects. Based on its reported biological activities, the effects of PG102 were examined on imiquimod-induced psoriasis-like skin inflammation. Our results showed that topical application of PG102 ameliorates clinical symptoms of psoriasis, reducing skin thickness and Interleukin (IL)-17A level in draining lymph nodes without causing any adverse effects. Treatment with PG102 on cytokine-stimulated HaCaT cells suppressed hyperproliferation and downregulated the expression of various chemokines and antimicrobial peptides known to induce neutrophil infiltration. These anti-inflammatory activities of PG102 were mediated via inhibition of NF-κB and signal transducer of activation (STAT) signaling. We also found decreased neutrophil chemotaxis both in vitro and in vivo. Taken together, PG102 has potential as a safe and effective reagent for the treatment of psoriasis.

Abstract
Psoriasis is characterized by excessive cell proliferation, angiogenesis, and regions of hypoxia. Hypoxia stimulates production of hypoxia inducible factors (HIFs) such as HIF1α. The aim of the present study is to investigate the possible role of HIF1α in pathogenesis of psoriasis and to correlate its expression with angiogenesis and proliferation in involved and uninvolved skin in patients with plaque psoriasis using CD34 and Ki-67. The current study was performed on 40 skin specimens of patients presented with chronic plaque psoriasis both involved and uninvolved together with 40 specimens from age- and sex-matched healthy volunteers as a control group. The specimens were submitted for HIF1α, CD34, and Ki-67 immunostaining. HIF1α was expressed in 37.5% of normal skin with mild intensity and cytoplasmic localization instead of its expression in 72.5% and 100% of uninvolved and involved psoriatic skin, respectively. Nucleocytoplasmic pattern of HIF1α was seen in 34.5% and 37.5% of uninvolved and involved psoriatic skin, respectively. Positive and intense expression of HIF1α as well as its nucleocytoplasmic localization were significantly in favor of psoriatic skin either involved or uninvolved in comparison to normal skin (P < 0.05). Intense HIF1α was significantly associated with microvessel density in both involved and uninvolved skin (P < 0.05). Nucleocytoplasmic pattern was significantly associated with epidermal acanthosis (P < 0.05) and tended to be associated with percentage of Ki-67 of psoriatic skin (P = 0.06). The present study demonstrated that HIF1α is upregulated in the skin of psoriatic cases (involved and uninvolved) compared to normal skin indicating its role in pathogenesis of psoriasis especially its active nuclear form that showed an association with angiogenesis and proliferation.

Abstract
INTRODUCTION Psoriasis is an autoimmune skin disease characterized by red plaques with silver or white multilayered scales with a thickened acanthotic epidermis. Using mouse models of cutaneous inflammation, IL-23/Th17 was identified to have a potential key role in psoriasis. New treatments to slow this inflammatory skin disorder are urgently needed. To aid their discovery, a psoriasis animal model mimicking human psoriasis is urgently needed for their early preclinical evaluation. Areas covered: The authors review animal models of psoriasis and analyze the features and molecular mechanisms involved in these mouse models. The application of various mouse models of psoriasis for drug discovery and development has also been reviewed and the possible molecular targets in psoriasis for future anti-psoriatic drug design is discussed. Expert opinion: So far, it has been difficult to create an animal model that exactly simulates a human disease or condition. The xenotransplantation model is regarded as the closest to incorporating the complete genetic, phenotypic, and immunopathogenic processes of psoriasis. However, the imiquimod (IMQ)-induced model is the most prevalent among psoriatic mouse models due to its ease of use, convenience, and low cost. Further efforts to develop psoriasis-like skin models in mice are needed for the study and treatment of this complex disease.

Abstract
Psoriasis is a chronic inflammatory disease of the skin affecting approximately 2% of the world's population. Systemic treatments, including methotrexate and cyclosporin, are associated with potential hepatotoxicity, due to either direct liver damage or immunosuppression or both immunomediated and a direct liver injury; therefore, treatment of patients with psoriasis poses a therapeutic challenge. The aim of this minireview is to help clinicians in the management of psoriatic patients who develop signs of liver dysfunction. To find relevant articles, a comprehensive search was performed on PubMed, EMBASE, and Cochrane with appropriate combinations of the following keywords being considered: viral hepatitis, nonalcoholic fatty liver disease, psoriasis, hepatotoxicity, drug toxicity, cholestasis, and autoimmune liver diseases.
