BACKGROUND: The inflammatory involvement of the enthesis in the course of psoriasis is accompanied by structural abnormalities detectable by ultrasound. The most common of these abnormalities is the thickening of the tendon at the insertion site. AIMS: The aim of the present study was to compare the thickness of entheses of patients with psoriatic arthritis, only skin psoriasis, and healthy controls. METHODS: A cross-sectional study was conducted in a cohort of patients affected with either only skin psoriasis or psoriatic arthritis as well as in a control group...

Generation of skin distribution profiles and reliable determination of drug molecule concentration in the target region are crucial during the development process of topical products for treatment of skin diseases like psoriasis and atopic dermatitis. Imaging techniques like mass spectrometric imaging (MSI) offer sufficient spatial resolution to generate meaningful distribution profiles of a drug molecule across a skin section. In this study, we use matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI-MSI) to generate quantitative skin distribution profiles based on tissue extinction coefficient (TEC) determinations of four different molecules in cross sections of human skin explants after topical administration...

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...

Psoriasis is a chronic inflammatory skin disorder associated with several comorbidities including atherosclerosis. Disease mechanisms that may affect both psoriasis and atherosclerosis include activation of T helper 1 and T helper 17 cells. Imiquimod application is an established mouse model of psoriasis-like skin inflammation. The cardiac glycoside digoxin inhibits the master transcription factor of T helper 17 differentiation, retinoid acid receptor-related orphan nuclear receptor γt, and attenuates interleukin-17-dependent pathologies in mice...

Psoriasis is a chronic inflammatory skin disease characterized by erythema, skin hyperplasia, scales, and keratinocyte hyperproliferation. While the cause of psoriasis is not clearly understood, a dysregulated immune system, especially activation of IL-23/IL-17 axis, has been strongly implicated in the pathogenesis of psoriasis. For example, anti-IL-23 therapy is effective in psoriasis patients, and thus IL-23 is considered as a potential therapeutic target for the treatment of psoriasis. The skin barrier provides protection of the human body against infection from external pathogens...

BACKGROUND: Psoriatic arthritis is a chronic inflammatory arthropathy that affects 14%-30% of patients with skin and/or nail psoriasis and leading to severe physical limitations and disability. It has been included in the group of spondyloarthropathy with which it shares clinical, radiologic, and serologic features in addition to familial and genetic relationship. Beyond skin and joint involvement, psoriatic arthritis is characterized by a high prevalence of extra-articular manifestation and comorbidities, such as autoimmune, infectious and neoplastic diseases...

BACKGROUND: Obesity is a disabilitating growing condition and represent a challenge for every surgeon. It is associated with the activation of the inflammatory pathway and this may have a negative impact on the natural history of some rheumatic diseases. Bariatric surgery, reducing obesity, could bring to a minor activation of the well-known inflammatory pathway with improvement of these diseases. The aim of this review is to investigate the role of weight loss, achieved through bariatric surgery, in rheumatic diseases...

Inflammatory-mediated reactions have been implicated as contributors in a number of dermatological disorders, including psoriasis. However, the potential of interleukin (IL)-32 and its isoforms to contribute to the pathogenesis of psoriasis remains unexplored. This study was undertaken to investigate the role of IL-32 and its isoforms IL-32α, IL-32β, IL-32γ, and IL-32δ in the peripheral blood of psoriatic patients. The majority of chronic plaque psoriatic patients showed elevated IL-32 mRNA levels in the peripheral blood mononuclear cells (PBMCs) as compared with the levels of IL-32 mRNA in PBMCs of healthy controls ( p = 0...

Optimizing combinations for psoriasis means asking patients to take control of their disease. It means balancing potency of steroids for the short-run to put out the fire and bring relief and maintaining the clearance for the long-run to reduce recurrence potential. Successful combinations are built on tolerability, ease of application, and the efficacy demonstrated by the synergy of the sum of the parts over being used separately. <p><em>J Drugs Dermatol. 2018;17(3):342-346.</em></p>...

Psoriasis vulgaris is a chronic inflammatory and immune-mediated skin disease. 44 metabonomics biomarkers were identified by high-throughput liquid chromatography coupled to mass spectrometry in our previous work. To further explore the roles of metabonomics biomarkers in the pathogenesis of psoriasis, the metabonomics biomarker-enzyme network was constructed. The key metabonomics biomarkers and enzymes were screened out by network analysis. Long-chain fatty acids, phospholipids, Estradiol and NADH were the most important metabonomics biomarkers...

BACKGROUND/OBJECTIVES: Allogeneic hematopoietic stem cell transplantation (HSCT) is a treatment option for many life-threatening disorders in children. Chronic graft-versus-host disease (cGVHD) is a significant complication of HSCT, and its treatment is challenging. Skin is the most common organ affected in cGVHD, with protean manifestations posing a challenge in diagnosis and management. The objective was to have a better understanding of the spectrum of chronic cutaneous GVHD (cc-GVHD) in children...

The IL-1 family member cytokine IL-36γ is recognised as key mediator in the immunopathology of psoriasis, hallmarks of which involve the activation of both resident and infiltrating inflammatory myeloid cells and aberrant angiogenesis. This research demonstrates a role for IL-36γ in both myeloid activation and angiogenesis. We show that IL-36γ induces the production of psoriasis-associated cytokines from macrophages (IL-23 and TNFα) and that this response is enhanced in macrophages from psoriasis patients...

Studies on the inflammatory burden in recent-onset psoriatic arthritis (PsA) patients without conventional cardiovascular risk factors (CVRFs) are not available. This preliminary study focuses on cardiovascular risk in cutaneous psoriasis (CPs) and recent-onset PsA patients. Blood biochemistry (glucose, cholesterol, uric acid, lipid profile and apolipoprotein B) was analyzed using standard kits. Proatherogenic inflammation markers, C-reactive protein (CRP) and interleukin-6 (IL-6), and endothelial activators monocyte chemoattractant protein-1 (MCP-1) and soluble intercellular adhesion molecule-1 (sICAM-1), were determined by enzyme-linked immunosorbent assay...

Dendritic cells (DCs) contribute to psoriasis pathogenesis. In a mouse model of imiquimod-induced psoriasiform skin inflammation, we found that p38α activity in Langerhans cells (LCs), a skin-resident subset of DCs, promoted the generation of T cells that produce IL-17, a proinflammatory cytokine that is implicated in autoimmune disease. Deletion of p38α in LCs, but not in other skin or circulating DC subsets or T cells, decreased T cell-mediated psoriasiform skin inflammation in mice. The activity of p38α in LCs specifically promoted IL-17 production from γδ and CD4+ T cells by increasing the abundance of IL-23 and IL-6, two cytokines that stimulate IL-17 secretion...
