Psoriatic arthritis (PsA) is a heterogeneous disease with various manifestations of musculoskeletal inflammation. Recent advances in imaging, including ultrasound (US) and magnetic resonance imaging (MRI), allow for the accurate evaluation of the extent of inflammation and damage in the peripheral joints, spine, and entheses. The development and validation of outcome measures are critical steps in creating standardized evaluations of musculoskeletal inflammation and damage in psoriatic patients. At the 2017 meeting of the Group for Research and Assessment of Psoriasis and PsA (GRAPPA), recent work on outcome measures from the GRAPPA US and MRI working groups was summarized...

Spondyloarthritis (SpA) encompasses a group of diseases characterized by an inflammatory arthritis involving both joints and entheses. However, extraarticular symptoms constitute a large element of the pathology and should not be underestimated. Microscopic gut inflammation is observed in 50% of patients with SpA and has been linked to disease activity, underscoring the effect of gut inflammation in SpA. In this review, we discuss the influence of gut microbiota on SpA pathogenesis. A change in microbiota composition has been linked to the development of various inflammatory arthritides, and dysbiosis is a potential factor in the pathogenesis of multiple inflammatory diseases...

The microbiome is a known and established immunomodulator of many inflammatory disorders, including psoriasis and psoriatic arthritis. Microbes co-evolved with their human hosts and provide them with nutritional, metabolic, and immunologic support. An accumulating body of evidence has revealed that psoriatic diseases are characterized by a state of intestinal dysbiosis, which has been linked to a decrease in beneficial commensals and fatty acids. This has been shown in both animal models and human samples, and multiple studies have addressed the physiological and potentially pathogenic role of intestinal and cutaneous microbes in human health and disease...

Psoriasis is a chronic, inflammatory immune-mediated skin disease that affects about 2% of the world's population. In 20% of patients with psoriasis, the characteristic skin lesions are accompanied by psoriatic arthritis (PsA). Psoriasis arises in genetically predisposed individuals who have a dysregulated immune response to various environmental factors. The human body is home to many microbial species, and both the skin and the gut microbiome influence the development and function of immune tissue development and function...

Juvenile psoriatic arthritis (JPsA), a subtype of juvenile idiopathic arthritis (JIA), constitutes 5% of JIA. The literature is inconsistent regarding features of JPsA, and physicians debate whether it is a distinct entity within JIA. A biphasic age of onset distribution has been noted. Early-onset disease is characterized by female predominance, small joint involvement, dactylitis, and positive antinuclear antibodies. Late-onset JPsA resembles adult-onset psoriatic arthritis (PsA), with male predominance, psoriasis, enthesitis, and axial disease...

Psoriatic arthritis (PsA) is a systemic inflammatory disease characterized by possible peripheral and axial joint involvement, enthesitis, dactylitis, and skin and nail disease. It affects up to one-third of psoriatic patients, and may be associated with comorbidities such as cardiovascular and metabolic diseases. The usually prescribed initial treatment of moderate-severe PsA is methotrexate, which may be accompanied or replaced by a tumor necrosis factor (TNF) inhibitor such as etanercept, infliximab, or adalimumab...

Psoriatic arthritis (PsA) is a chronic inflammatory disease affecting peripheral and axial joints, usually associated with psoriasis (PsO) and involving various systems and organs (eye inflammation, such as uveitis; and involvement of nail and enthesis), and it usually requires a multidisciplinary treatment approach. Tumor necrosis factor-α (TNF-α) is overexpressed in psoriatic synovium and skin plaques and its selective inhibition by anti-TNF-α agents has been demonstrated to reduce TNF-α levels in the articular environment, reversing the synovial hyperproliferative phenotype...

The pathogenesis of psoriatic arthritis (PsA) is still under discussion but great advances have been made in the last 2 decades that confirm the central role of tumor necrosis factor-α (TNF-α) in its inflammatory milieu. New therapeutic approaches have been proposed, and new molecules with anti-TNF-α activity have been chemically altered to improve their pharmacological properties. Certolizumab pegol (CZP) is a PEGylated Fc-free anti-TNF that has been shown clinically to be effective in the treatment of rheumatoid arthritis (RA), skin psoriasis, and PsA...

Treatment with nonsteroidal antiinflammatory drugs (NSAID) is the recommended first-line therapy in patients with axial spondyloarthritis (axSpA); and for those patients who have persistently active disease, the introduction of tumor necrosis factor-α (TNF-α) inhibitors is indicated. Conventional nonbiological disease-modifying antirheumatic drugs (DMARD), although effective and used in clinical practice for peripheral arthritis, are not recommended. Few studies have been conducted with the aim of evaluating the effect of conventional DMARD, either alone or in combination, in axSpA...

We present an update on the effects of methotrexate (MTX), sulfasalazine (SSZ), leflunomide (LEF), and cyclosporine (CSA) in psoriatic arthritis (PsA) by reviewing data published from January 2010 to June 2014. The most relevant study on MTX, the Methotrexate In Psoriatic Arthritis (MIPA) trial, did not show a significant difference between this drug and placebo in improving peripheral synovitis. The trial, however, had several limitations. A cohort study on a small number of patients found that MTX does not inhibit radiographic progression...

Psoriasis is a lifelong chronic inflammatory disease affecting 2-3% of the worldwide population. Current understanding of the pathogenesis of psoriasis assigns central importance to an interaction between acquired and innate immunity. The disease is characterized by a series of linked cellular changes in the skin, including hyperplasia of epidermal keratinocytes, angiogenesis, and infiltration of T lymphocytes, neutrophils, and other types of leukocytes in the affected skin. Plaque psoriasis is the most common clinical form and is characterized by red and scaly plaques generally localized at extensor sites such as elbows and knees...
