The IL-23/IL-17 pathway is implicated in autoimmune diseases, particularly psoriasis, where biologics targeting IL-23 and IL-17 have shown significant clinical efficacy. Retinoid-related orphan nuclear receptor gamma t (RORγt) is required for Th17 differentiation and IL-17 production in adaptive and innate immune cells. We identified JNJ-54271074, a potent and highly-selective RORγt inverse agonist, which dose-dependently inhibited RORγt-driven transcription, decreased co-activator binding and promoted interaction with co-repressor protein...

Tumor necrosis factor (TNF)-α is a potent pro-inflammatory cytokine exerting pleiotropic effects on various cell types. It is synthesized in a precursor form called transmembrane TNF-α (mTNF-α) which, after being processed by metalloproteinases, is released in a soluble form to mediate its biological activities through Type 1 and 2 TNF receptors in TNF receptor expressing cells. In addition to acting in soluble form, TNF-α also acts in the transmembrane form both as a ligand by activating TNF receptors, as well as a receptor that transmits outside-to-inside (reverse) signals back into mTNF-α bearing cells...

Autoimmune diseases often share common susceptibility genes. Most genetic variants associated with susceptibility to systemic lupus erythematosus are also associated with other autoimmune diseases. The X-linked variant rs2294020 is positioned in exon 7 of the CCDC22 gene. The encoded protein functions in the regulation of NF-kB, a master regulator in immune response. The aim of this study is to investigate whether the rs2294020 polymorphism may be a general susceptibility factor for autoimmunity. We evaluated case-control association between the occurrence of rs2294020 and different autoimmune diseases, including new data for systemic lupus erythematosus and previous genome-wide association studies (GWAS) (though most did not analyse the X chromosome) of psoriasis, celiac disease, Crohn's disease, ulcerative colitis, multiple sclerosis, vitiligo, type-1 diabetes, rheumatoid arthritis, and ankylosing spondylitis...

Ultrasound (US) is a rapidly evolving technique that is gaining increasing success in the assessment of psoriatic arthritis (PsA). Recently, new research avenues have been opened, and these are focused on the potential of US for the assessment of extra musculoskeletal areas such as skin and nails. This permits work on the concept of 'holistic US assessment of PsA'. Areas covered: Here, we analyze the potential role of US in the global assessment of PsA. Additionally, we provide the current evidence supporting its application in routine clinical practice...

Psoriasis is a chronic, immune-mediated disorder with cutaneous and systemic manifestations and substantial negative effects on patient quality of life. Psoriasis has a strong, albeit polygenic, genetic basis. Whereas approximately half of the accountable genetic effect of psoriasis maps to the major histocompatibility complex, >70 other loci have been identified, many of which implicate nuclear factor-κB, interferon signalling and the IL-23-IL-23 receptor axis. Psoriasis pathophysiology is characterized by abnormal keratinocyte proliferation and immune cell infiltration in the dermis and epidermis involving the innate and adaptive immune systems, with important roles for dendritic cells and T cells, among other cells...

Although infliximab is approved for psoriasis, its efficacy is reduced over time in some patients. The aim of this phase III trial is to evaluate efficacy and safety of infliximab dose escalation in Japanese psoriasis patients with loss of efficacy to standard-dose therapy. Patients with plaque psoriasis, psoriatic arthritis, pustular psoriasis or psoriatic erythroderma who showed loss of efficacy to standard-dose therapy received infliximab dose escalation (10 mg/kg every 8 weeks) from weeks 0 to 32. Loss of efficacy was defined as not maintaining 50% reduction in the Psoriasis Area and Severity Index (PASI 50) after achieving PASI 75...

The clinical course of axial spondyloarthritis (SpA) is variable and characterized by chronic back pain and extraspinal manifestations, such as asymmetrical arthritis, dactylitis and enthesitis. Extra-articular manifestations in the eyes (anterior uveitis), skin (psoriasis) and intestines (chronic inflammatory bowel disease) are also frequent manifestations in patients with SpA. Due to the heterogeneity of disease manifestations and the partial concentration on structural alterations in the sacroiliac joints visible in X‑ray images, the diagnosis is often delayed for many years...

Biologics are substances made from a living organism or its products. These include genes, proteins (eg, antibodies, receptors, enzymes, inhibitors), recombinant proteins, and fusion proteins. Biologics often are produced using recombinant DNA technology. For example, monoclonal antibodies are produced by inserting human genes into immortalized cell cultures, which then produce the gene product (ie, an antibody) in large quantity. Another approach is to fuse genetic material from nonhuman sources (eg, mice) with human genetic material...

BACKGROUND: Although subclinical enthesopathy is a well-established diagnostic criterion for psoriatic arthritis (PsA), it is frequently overlooked, as many patients are asymptomatic. The possibility of finding a clinical clue predicting enthesopathy would help clinicians establish an early diagnosis of PsA. MATERIAL AND METHODS: A prospective single-center study of a total of 90 patients with psoriasis was conducted to assess the presence of entheseal abnormalities as detected by ultrasound, and to determine any correlation with nail involvement...

Wnt5a initiates pro-inflammatory responses through activation of non-canonical Wnt signaling pathway. Pro-inflammatory functions of Wnt5a trigger pro-inflammatory signaling cascades and increase secretion of pro-inflammatory cytokines and chemokines. Wnt5a as a potent signaling molecule is strongly implicated in a number of diseases including cancer, diabetes, metabolic disorders, and of special interest in this review, inflammatory diseases. This review summarizes the role of Wnt5a in the pathogenesis of inflammatory diseases including atherosclerosis, rheumatoid arthritis, psoriasis vulgaris and sepsis, promoting greater understanding and clinical management of these diseases...

Certolizumab pegol (CZP) is a pegylated humanized tumor necrosis factor-α inhibitor (TNFi) approved for the treatment of psoriatic arthritis (PsA) in Europe, the USA, and Latin American countries. CZP neutralizes TNF-α at its soluble and membrane portions. Due to the lack of Fc region, it does not induce complement or antibody-dependent cytotoxicity in vitro, unlike other TNFi. RAPID-PsA study, the only randomized clinical trial performed in PsA, is a Phase III clinical trial conducted in 409 PsA patients during 24 weeks...

Psoriatic arthritis (PsA) is a heterogeneous disease that can involve a variety of distinct anatomical sites including a patient's peripheral and axial joints, entheses, skin and nails. Appropriate management of PsA requires early diagnosis, monitoring of disease activity, and utilization of cutting edge therapies. To accomplish the former there are a variety of PsA-specific tools available to screen, diagnose, and assess patients. This review will outline the recently developed PsA screening tools, including the Toronto Psoriatic Arthritis Screening Questionnaire (TOPAS), the Psoriasis Epidemiology Screening Tool (PEST), the Psoriatic Arthritis Screening and Evaluation (PASE), and the Psoriasis and Arthritis Screening Questionnaire (PASQ)...

Psoriatic arthritis (PsA) is a heterogeneous, potentially severe disease. Many therapeutic agents are now available for PsA, but treatment decisions are not always straightforward. To assist in this decision making, two sets of recommendations for the management of PsA were published in 2016 by international organizations - the European League Against Rheumatism (EULAR) and the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA). In both sets of recommendations, the heterogeneity of PsA is recognized and the place of various drugs in the therapeutic armamentarium is discussed...

Adenosine, a nucleoside derived primarily from the extracellular hydrolysis of adenine nucleotides, is a potent regulator of inflammation. Adenosine mediates its effects on inflammatory cells by engaging one or more cell-surface receptors. The expression and function of adenosine receptors on different cell types change during the course of rheumatic diseases, such as rheumatoid arthritis (RA). Targeting adenosine receptors directly for the treatment of rheumatic diseases is currently under study; however, indirect targeting of adenosine receptors by enhancing adenosine levels at inflamed sites accounts for most of the anti-inflammatory effects of methotrexate, the anchor drug for the treatment of RA...
