There is not a strong correlation between the severity of psoriasis and the development of arthritis although psoriatic arthritis may be present more frequently in patients with psoriasis attending dermatology clinics, compared to primary care. DIP cases may have erosion and deformity with bony ankylosis of the joint and subluxation. Methotrexate may be considered in the treatment of psoriatic arthritis, especially when associated with significant cutaneous psoriasis. However, a substantial number of patients may lose efficacy, have adverse effects or find intravenous or subcutaneous administration inconvenient. Shared attributes of cutaneous psoriasis and psoriatic arthritis 1014. Because most patients will be treated first for the skin lesions associated with psoriasis, dermatologists are in a unique position to screen for and diagnose early PsA 3, 35, 36.

There are five main types of psoriasis: plaque, guttate, inverse, pustular, and erythrodermic. About 75 of cases can be managed with creams alone. Psoriatic arthritis is a form of chronic inflammatory arthritis that has a highly variable clinical presentation and frequently occurs in association with skin and nail psoriasis. Sunlight, on the other hand, will improve most patients’ psoriasis 107. Psoriasis varies in its cutaneous manifestations and sites of involvement.
In most patients, the musculoskeletal symptoms are insidious in onset, but an acute onset has been reported in one third of all patients. Skin lesions include scaly, erythematous plaques; guttate lesions; lakes of pus; and erythroderma. Hip and knee joint replacements have been successful. Psoriatic nail disease has many clinical signs. Most psoriatic nail disease occurs in patients with clinically evident psoriasis; it only occurs in less than 5 of patients with no other cutaneous findings of psoriasis. Patient information: Psoriasis (Beyond the Basics). The inner layer is the subcutaneous layer, a layer of fat underneath the skin. Every day, as cells in the epidermis die and become part of the stratum corneum, dead cells at the top of the stratum corneum also are shed. Some of the most common areas for plaques are the scalp, elbows, knees, and back (picture 1). People with psoriatic arthritis often have severe nail problems.
The presence of cutaneous psoriasis is important for correct and early diagnosis of PsA, because the onset of cutaneous lesions usually precedes the appearance of joint manifestation. Psoriatic arthritis (PsA) is a chronic inflammatory arthropathy associated with psoriasis. Although most patients with PsA have moderate to severe skin disease,1 the severity of cutaneous psoriasis varies from subtle (sine psoriasis) to erythrodermic conditions. Four clinical variants of psoriasis (Guttate psoriasis, psoriasis vulgaris, C. Psoriasis patients are not only more likely to have CV risk factors but severe psoriasis may serve as an independent risk factor for CV mortality.

Total hip arthroplasty (THA) in patients with psoriasis has not been thoroughly studied, the researchers wrote. Whether patients with psoriatic arthritis or cutaneous psoriasis and osteoarthritis are at an increased risk for worse outcomes after arthroplasty as compared to patients with osteoarthritis, is unknown because it has never before been studied. The procedure is most commonly performed in patients with osteoarthritis, but the existing literature on outcomes in psoriatic arthritis is sparse. Patients with more severe disease have tried a number of different disease-modifying drugs including methotrexate, azathioprine, and gold salts. Although the exact cause of the cutaneous and musculoskeletal changes of psoriasis are unknown, they seem to be the result of a combination of genetic, immunologic, and environmental factors 7 10. Approximately 90 percent of affected patients have plaque psoriasis, characterized by well-defined round or oval plaques that differ in size and often coalesce6 (Figure 1). Guttate psoriasis is more common in patients younger than 30 years, and lesions are usually located on the trunk. Psoriatic arthritis is a seronegative inflammatory arthritis with various clinical presentations. Delayed diagnosis of psoriatic arthritis (PsA) can have profound effects, such as irreversible joint damage, poor quality of life, and decreased response to treatment; however, many cases of PsA are not diagnosed until up to 2 years after onset of symptoms. Saakshi Khattri discusses screening questions for PsA that dermatologists should address when treating patients with psoriasis and emphasizes that collaboration between dermatologists and rheumatologists is essential to early diagnosis and treatment of PsA.
