    ABSTRACT: Psoriasis is a common, chronic inflammatory skin disease most often appearing in the form of well-demarcated, scaly plaques. These lesions highlight the fundamental processes underlying its pathogenesis, namely, inflammation and epidermal hyperproliferation. Both phenomena are considered consequences of an intimate interplay between the innate and the adaptive immune system. This concept is supported by results of genetic studies, pointing toward the signaling pathways of nuclear factor-κB, interferon-γ, and interleukin (IL)-23 as well as antigen presentation as central axes of the psoriatic inflammation. Efficacy of biologics targeting tumor necrosis factor-α, IL-23, or IL-17 provides further evidence in favor of this model.

    ABSTRACT: Psoriasis primarily affects the skin, but also has a systemic dimension and is associated with severe comorbidities. Since endothelial cells play an important role in psoriasis as well as in the development of cardiovascular comorbidities, we investigated whether a common mechanism, namely cytokine-induced insulin resistance, underlies both pathologies. Activation of the insulin pathway was studied in psoriatic skin and dermal endothelial cells. Expression of adhesion molecules was assessed by flow cytometry, as well as their biological function in flow chamber experiments. The phosphorylation status of Akt, a central kinase in the insulin pathway, suggests that endothelial cells within psoriatic plaques are rendered insulin resistant by pro-inflammatory cytokines. Insulin counteracts the expression of adhesion molecules, but has limited effects on interactions between T cells and endothelial cells. Pro-inflammatory cytokines induce insulin resistance in endothelial cells, which may contribute to the development of the inflammatory infiltrate in psoriasis.

    ABSTRACT: Psoriasis is an immune-mediated, genetic disease manifesting in the skin or joints or both. A diverse team of clinicians with a range of expertise is often needed to treat the disease. Psoriasis provides many challenges including high prevalence, chronicity, disfiguration, disability, and associated comorbidity. Understanding the role of immune function in psoriasis and the interplay between the innate and adaptive immune system has helped to manage this complex disease, which affects patients far beyond the skin. In this Seminar, we highlight the clinical diversity of psoriasis and associated comorbid diseases. We describe recent developments in psoriasis epidemiology, pathogenesis, and genetics to better understand present trends in psoriasis management. Our key objective is to raise awareness of the complexity of this multifaceted disease, the potential of state-of-the-art therapeutic approaches, and the need for early diagnosis and comprehensive management of patients with psoriasis.

    ABSTRACT: Psoriasis has long been regarded to be one entity, comprising both plaque-type and non plaque-type manifestations. Genetic studies now provide evidence that some pustular forms should be classified separately: a mutation in the gene encoding for the interleukin 36 receptor antagonist (IL36Ra) was f6und to be associated with generalized pustular psoriasis (GPP) in several Tunesian families. This finding was subsequently confirmed in different psoriasis cohorts around the world. Additionally, gain-of-function mutations in the gene for CARD 14 were identified. Clinical implications comprise a different approach to treat GPP through blocking interleukin 1beta.

    ABSTRACT: Background: Psoriatic arthritis (PsA) substantially impacts the management of psoriatic disease. Objective: This study aimed to generate an interdisciplinary national consensus on recommendations of how PsA should be managed. Methods: Based on a systematic literature search, an interdisciplinary expert group identified important domains and went through 3 rounds of a Delphi exercise, followed by a nominal group discussion to generate specific recommendations. Results: A strong consensus was reached on numerous central messages regarding the impact of PsA, screening procedures, organization of the interaction between dermatologists and rheumatologists, and treatment goals. Conclusion: These recommendations can serve as a template for similar initiatives in other countries. At the same time, they highlight the need to take into account the impact of the respective national health care system. © 2015 S. Karger AG, Basel.

    ABSTRACT: Actinic keratosis (AK) affects millions of people worldwide, and its prevalence continues to increase. AK lesions are caused by chronic ultraviolet radiation exposure, and the presence of two or more AK lesions along with photodamage should raise the consideration of a diagnosis of field cancerization. Effective treatment of individual lesions as well as field cancerization is essential for good long-term outcomes. The Swiss Registry of Actinic Keratosis Treatment (REAKT) Working Group has developed clinical practice guidelines for the treatment of field cancerization in patients who present with AK. These guidelines are intended to serve as a resource for physicians as to the most appropriate treatment and management of AK and field cancerization based on current evidence and the combined practical experience of the authors. Treatment of AK and field cancerization should be driven by consideration of relevant patient, disease, and treatment factors, and appropriate treatment decisions will differ from patient to patient. Prevention measures and screening recommendations are discussed, and special considerations related to management of immunocompromised patients are provided.

    ABSTRACT: Numerous guidelines and recommendations exist for the treatment of psoriasis in various populations. One important population is patients with psoriatic arthritis (PsA) who have symptoms of both joint and skin disease. In patients with both facets of psoriatic disease, skin and joints must be treated separately, but also simultaneously. As several systemic therapies are approved for either one or both, the concept of treating both facets with the same drug is feasible. This review summarizes evidence from studies in patients with PsA on the efficacy of these drugs on psoriatic skin disease in these patients.

    ABSTRACT: In the United States, access to care is the number one issue facing our patients with dermatological conditions. In part, this is because we do not have outcome measures that are useful in clinical practice and available in databases where payers and governmental agencies can compare the performance of physicians and treatments. There is a growing recognition that insufficient attention has been paid to the outcomes measured in clinical trials and subsequently in clinical practice. The International Dermatology Outcome Measures group includes all willing stakeholders: patients, physicians, payers, and pharmaceutical scientists. As reported herein, the group's goal is to develop outcome measures in dermatology that address the needs of all involved.

    ABSTRACT: It is now well established that psoriatic disease is associated with increased cardiovascular (CV) risk. Screening guidelines and expert recommendations for CV risk factors have been published, but these are primarily directed to specific specialists (e.g., cardiologists or diabetologists) and may not be well known in common practice. The Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) and other organizations are interested in adapting current comorbidity screening guidelines for use by dermatologists and rheumatologists. The resulting checklists and algorithms will need to be evaluated for practicability and performance.

    ABSTRACT: Psoriasis is among the most common skin diseases, exhibiting a wide spectrum of clinical manifestations. Joint involvement in the form of psoriatic arthritis is readily recognised, but both frequency and severity of this manifestation have long been underestimated. More recently, additional important diseases have been found to be associated with psoriasis, including the metabolic syndrome (or components thereof), cardiovascular diseases, lymphoma, and anxiety/depression. In the past, psoriasis treatment aimed at suppressing acute rashes. Current concepts regard psoriasis as a chronic systemic inflammatory condition and cardiovascular risk factor. In the light of this concept, long-term disease control through systemic maintenance therapy is increasingly recommended by experts. This approach became feasible with the approval of numerous biologics for the treatment of psoriasis. But to really address all medical needs of psoriasis patients, a truly interdisciplinary, comprehensive management approach is needed. Several national societies have already published algorithms to ensure that this need will be implemented in the daily practice of dermatologists and nondermatologists alike.

    ABSTRACT: The German psoriasis registry PsoBest records the long-term efficacy, safety, patient benefit and treatment regimens of psoriasis. Patients with moderate or severe psoriasis are included in PsoBest when treatment with a conventional systemic agent or biologic is started for the first time. Observation time is five years. Standardized physician and patient case report forms are obtained every three to six months. Baseline data of patients included by 31 December 2012 are presented and compared to the national health care study PsoHealth 2007 (n = 2,009). 602 dermatology practices and clinics have been registered and 199 have recruited n = 2,556 patients (63 % by practices, 37 % by clinics). Initially, n = 808 received biologics (316 adalimumab, 34 efalizumab, 209 etanercept, 75 infliximab, 22 golimumab, 152 ustekinumab) and n = 1,651 conventional systemic therapy (928 fumaric acid esters, 518 methotrexate, 161 cyclosporine A, 191 other drugs or UV treatment). Compared to PsoHealth, patients in PsoBest had on average a higher disease severity (PASI 14.7 vs. 10.1; DLQI 11.0 vs. 7.5; EQ-5D VAS 54.0 vs. 64.5), shorter disease duration (18.2 vs. 21.3 yrs.), lower age (47.3 vs. 51.5), higher rates of psoriatic arthritis (20.5 vs. 19.1 %) and nail psoriasis (55.0 vs. 35.6 %). On average patients receiving biologics were younger, more often male and had higher disease severity and comorbidity. Patients in PsoBest represent patients with a high burden of disease.

    ABSTRACT: Cytosolic Ca(2+) signals are performed by Ca(2+) releases from the endoplasmic reticulum and Ca(2+) influx from the extracellular medium. Releases rely on the refilling of the intracellular Ca(2+) stores by the Ca(2+) influx "Store Operated Ca(2+) Entry" (SOCE) via the channel Orai1. Here we show that Orai1 expression, SOCE amplitude and epidermal proliferation are decreased in the epidermis of patients with skin fragility when compared to aged non-atrophic skin. Epidermal atrophy was induced in mice by the inhibition of Orai1 with small interfering RNA and the topical application of a SOCE blocker, BTP2. The inhibition of Orai1 impaired the HB-EGF-induced Ca(2+) influxes and fully prevented the mitogen effect of HB-EGF in primary human keratinocytes (PHK). Importantly, epidermal proliferation correlated with Orai1 expression in mice. Conversely, the topical application of an Orai1-activator, the benzohydroquinone (BHQ), increased epidermal thickness and proliferation while the pro-proliferative effect of BHQ was prevented by the inhibition of Orai1. Finally, the topical application of BHQ reversed the epidermal atrophy induced by corticosteroids in mice. The topical modulation of Ca(2+) signals may thus be a promising therapeutic strategy in dermatology.Journal of Investigative Dermatology accepted article preview online, 6 December 2013. doi:10.1038/jid.2013.524.

    ABSTRACT: The endothelial wall plays a crucial role in various diseases as it serves as the barrier between circulatory system and organ tissue. Inflammation-driven insulin resistance and subsequent endothelial dysfunction represent a pathomechanism in cardiovascular diseases such as atherosclerosis and myocardial infarction. It was recently suggested that insulin resistance also contributes to the pathogenesis of psoriasis, a chronic inflammatory disease of the skin. However, it is not clear whether similar mechanisms at the endothelium contribute to the disease. In this study, we ask which endothelial cells are most suitable to address this question. We investigated the insulin response of four cell types (primary cells and cell lines) representing different vascular beds (micro- and macrovascular cells) in the presence of different pro-inflammatory cytokines. All four cell types used responded well to insulin; however, the ability to become resistant to insulin due to an inflammatory stimulus by cytokines involved in psoriasis (e.g. IL-1β, IL-12, IL-17, IL-23 and TNF-α) was very heterogeneous and could not be attributed to the differential expression of the cognate cytokine receptors. We conclude that this disparity is due to the different origins and properties of the endothelial cells used. Thus, endothelial cells should be carefully selected for the purpose of the respective study, particularly when it comes to analysing the pathogenesis of a disease and the search of new molecular targets for innovative therapies.

    ABSTRACT: Psoriasis is a common chronic inflammatory skin disease, associated with significant comorbidity, for example, metabolic syndrome (MetS) and coronary heart disease (CHD). This association implies that the risk to develop these diseases is commonly controlled or that the presence of one disease favours manifestation of the other. Therefore, we assessed the catalogue of genome-wide association studies (GWAS) to analyse whether psoriasis, MetS and CHD share susceptibility loci. Interestingly, genetic control of psoriasis is almost completely independent from both MetS and CHD. In contrast, MetS and CHD share 10 common loci. Like by GWAS analysis, psoriasis susceptibility genes showed close clustering in Ingenuity Pathway Analysis, while genes conferring susceptibility to MetS and CHD were interlinked separately. These findings lead to the hypothesis that the clinically observed co-occurrence of psoriasis with MetS and CHD may be due to a common environmental factor, for example, diet, which is known as a risk factor for all of these diseases.
