Psoriatic arthritis: An update on classification, clinical features and therapies

Psoriatic arthritis (PsA) is a chronic systemic inflammatory disease characterized by joint inflammation and cutaneous psoriasis. With advances in knowledge of genetics, immunohistology and pathogenesis, PsA is now recognized as a distinct disease entity. Unique clinical features include distal interphalangeal joint (DIPJ) involvement, dactylitis, enthesitis, axial involvement, specific radiographic features, and specific skin and nail changes. PsA affects young adults and is progressive and destructive, causing deformities, impaired physical function, reduced quality of life and lost of productivity. We now focus on more aggressive treatment in patients with progressive disease. With both conventional disease modifying anti-rheumatic drugs (DMARDs) and emerging biological agents, the outlook for patients with PsA has improved.

Psoriatic arthritis – new perspectives

Archives of Medical Science

Psoriatic arthritis (PsA) is a seronegative arthropathy with many clinical manifestations, and it may affect nearly a half of patients with psoriasis. PsA should be diagnosed as early as possible to slow down joint damage and progression of disability. To improve the diagnosis of PsA, physicians should look for peripheral inflammatory pain, axial inflammatory pain, dactylitis, and buttock and sciatic pain. In most patients with PsA, pharmacologic treatment with non-steroidal anti-inflammatory drugs, disease-modifying anti-rheumatic drugs, and biologic agents is effective. However, when pharmacological treatment fails, patients with PsA may benefit from orthopedic surgery, which can improve both joint function and quality of life. Total hip arthroplasty, total knee arthroplasty, and arthroscopic synovectomy of the knee are the most common surgical procedures offered to patients with PsA. The management of PsA requires the care of a multidisciplinary team, which should include dermatologists, rheumatologists, physiotherapists, and orthopedic surgeons.

Psoriatic arthritis: one year in review 2022

Clinical and Experimental Rheumatology

Psoriatic arthritis is a systemic autoimmune disease, in which a characteristic heterogeneous inflammatory involvement of entheses and both peripheral and axial joints tends to be associated with different clinical features, in particular skin or nail psoriasis, but also inflammatory bowel diseases, or acute anterior uveitis. Patients with PsA are at higher risk of developing comorbidities, in particular metabolic syndrome, with a significant impact on their quality of life. Although the advanced knowledge in the pathogenetic mechanisms of PsA helped in developing an abundant therapeutical armamentarium, the available drugs might still show a suboptimal efficacy. However, the frontier of "personalised medicine" could promote further future improvement in the quality of care of patients. In this paper we reviewed the literature on PsA of 2020 and 2021 (Medline search of articles published from 1st January 2020 to 31th December 2021).

One year in review 2018: psoriatic arthritis

2019

Spondyloarthritis (SpA) is an inflammatory condition characterised by a broad spectrum of clinical manifestations, laboratory abnormalities and imaging features that genetically tend to be associated with the major histocompatibility complex class 1 antigen, HLA-B27, and in which both peripheral and axial joints might be affected. In addition to arthritis, the typical musculoskeletal manifestations are enthesitis and dactylitis. Extraarticular manifestations such as acute anterior uveitis (AAU), psoriasis (PsO) and inflammatory bowel disease (IBD) are also typical of SpA. In this article we have reviewed the literature of the past year on one of the most important variants of SpA, i.e. psoriatic arthritis (PsA) (Medline search of articles published from 1st January 2018 to 31st January 2019).

Evaluation and management of psoriatic arthritis: the role of biologic therapy

Journal of the American Academy of Dermatology, 2003

Clinicians often view psoriatic arthritis (PsA) as a rather minor arthritic disorder because many are unaware of the substantial damage, disability, and reduced quality of life that patients with this disease can suffer. Compared with better-studied arthritic conditions, such as rheumatoid arthritis (RA) with well-known consequences of disease progression, PsA does not elicit the same urgency to treat early and aggressively. This is largely owing to the lack of predictive epidemiologic data regarding disease progression in PsA. However, numerous studies indicate that PsA and RA are comparable in terms of overall severity of joint involvement and disability over equivalent disease duration. Many of the drugs traditionally used for PsA therapy are also used to treat RA, including nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids, methotrexate (MTX), sulfasalazine, cyclosporine, etretinate, auranofin, intramuscular gold, and azathioprine. All of these drugs have significant risk of toxicity over long-term use, and all provide variable efficacy. This makes it difficult for clinicians to make sound risk-benefit assessments regarding treatment or nontreatment of PsA, because the risks of disease progression cannot be weighed against the risks of therapy. The newer biologic antirheumatic drugs appear to combine greater efficacy of treatment with significantly less toxicity by targeting specific mediators involved in the pathogenesis of PsA.

Burden of Disease: Psoriasis and Psoriatic Arthritis

American Journal of Clinical Dermatology, 2013

Psoriatic arthritis (PsA) increases the disease burden associated with psoriasis by further diminishing quality of life, increasing health care costs and cardiovascular risk, and potentially causing progressive joint damage. The presence of PsA influences psoriasis treatment by increasing overall disease complexity and, within the framework of current guidelines and recommendations, requiring the use of conventional disease-modifying antirheumatic drugs or tumor necrosis factor-a inhibitors in order to prevent progressive joint damage. Despite its important impact, PsA is still under-diagnosed in dermatology practice. Dermatologists are well positioned to recognize and treat PsA, given that it characteristically presents, on average, 10 years subsequent to the appearance of skin symptoms. Regular screening of psoriasis patients for early evident joint symptoms should be incorporated into daily dermatologic practice. Although drugs effective in PsA are available, not all patients may respond to treatment, and others may lose their initial response over time. New investigational therapies, such as inhibitors of interleukin-17A, interleukin-12/23, Janus kinase 3, or phosphodiesterase-4, may address unmet needs in psoriatic disease, with further research needed to determine the role of these agents in reducing joint damage and other comorbidities.

Steps in the management of psoriatic arthritis: a guide for clinicians

Therapeutic Advances in Chronic Disease, 2012

Psoriatic arthritis is a common systemic inflammatory disorder, which in addition to skin and nail involvement may be associated with peripheral and axial joint involvement, enthesitis, dactylitis, and important comorbidities – especially cardiovascular morbidity. Better insights into the involved pathogenic mechanisms have resulted in an improved therapeutic armamentarium, which targets key pathways in its pathogenesis. This has resulted in significant clinical responses to newer therapeutic agents, especially those directed at inhibition of tumor necrosis factor α. Biological therapy leads to significant levels of remission, improved quality of life, and retards or improves structural radiological damage.

Psoriatic arthritis: A permanent new challenge for dermatologists (Review)

Experimental and Therapeutic Medicine, 2019

Considering that most of the patients (>2/3) are diagnosed with psoriasis in the cutaneous form long before the joint damage occurs and, in these conditions, a significant proportion of them is found in the dermatologist's initial records, a question must be asked: when is it necessary to send these patients to a rheumatology consultation? The recognition of psoriatic arthritis in patients with vulgar psoriasis and the dermatologist's ability to differentiate it from other arthritis, offers the opportunity to improve patient prognosis by prompt intervention and close collaboration with the rheumatologist. Diagnosis of early psoriatic arthropathy should be considered when a patient with psoriasis or family history of psoriasis has peripheral inflammatory arthritis (oligoarthritis or distal interphalangeal joints damage), enthesitis, dactylitis, spinal pain of inflammatory type. Given that patients with psoriasis are included in the dermatologists' medical records, it is very important to recognize psoriatic arthritis in patients with cutaneous psoriasis, to differentiate it from other possible arthritis, thus having the possibility to improve patient prognosis by prompt intervention and through collaboration with the rheumatologist.
