can cause other inflammatory complications including cardiovascular complications. A study used fluorodeoxyglucose F-18 positron emission tomography computed tomography (FDG PET/CT) to measure aortic vascular inflammation in psoriasis patients, and found increased coronary artery disease indices, including total plaque burden, luminal stenosis, and high-risk plaques in people with psoriasis. Similarly, it was found that there is 11% reduction in aortic vascular inflammation when there is 75% reduction in PASI score.
1199:) and an overabundance of skin cells result from the sequence of pathological events in psoriasis. The sequence of pathological events in psoriasis is thought to start with an initiation phase in which an event (skin trauma, infection, or drugs) leads to activation of the immune system and then the maintenance phase consisting of chronic progression of the disease. Skin cells are replaced every 3–5 days in psoriasis rather than the usual 28–30 days. These changes are believed to stem from the premature maturation of 2260: 640: 1906: 1625: 522: 2221:(DHA). A low-calorie diet appears to reduce the severity of psoriasis. Diet recommendations include consumption of cold water fish (preferably wild fish, not farmed) such as salmon, herring, and mackerel; extra virgin olive oil; legumes; vegetables; fruits; and whole grains; and avoid consumption of alcohol, red meat, and dairy products (due to their saturated fat). The effect of consumption of caffeine (including coffee, black tea, mate, and dark chocolate) remains to be determined. 1260:(DNA) released from dying cells acts as an inflammatory stimulus in psoriasis and stimulates the receptors on certain dendritic cells, which in turn produce the cytokine interferon-α. In response to these chemical messages from dendritic cells and T cells, keratinocytes also secrete cytokines such as interleukin-1, interleukin-6, and tumor necrosis factor-α, which signal downstream inflammatory cells to arrive and stimulate additional inflammation. 792: 498: 510: 558: 681:(erythrodermic psoriasis) involves widespread inflammation and exfoliation of the skin over most of the body surface, often involving greater than 90% of the body surface area.

The diminished CD4+-T cell presence is thought to cause an overactivation of CD8+-T cells, which are responsible for the exacerbation of psoriasis in HIV-positive people. Psoriasis in those with HIV/AIDS is often severe and may be untreatable with conventional therapy. In those with long-term, well-controlled psoriasis, new HIV infection can trigger a severe flare-up of psoriasis and/or psoriatic arthritis. 1809:
tanning is already used by many people as a treatment for psoriasis; one indoor facility reported that 50% of its clients were using the center for psoriasis treatment; another reported 36% were doing the same thing. However, a concern with the use of commercial tanning is that tanning beds that primarily emit UVA might not effectively treat psoriasis. One study found that plaque psoriasis is responsive to

A much higher rate of psoriatic arthritis occurs in HIV-positive individuals with psoriasis than in those without the infection. The immune response in those infected with HIV is typically characterized by 348:. Plaque psoriasis, also known as psoriasis vulgaris, makes up about 90% of cases. It typically presents as red patches with white scales on top. Areas of the body most commonly affected are the back of the forearms, shins, navel area, and scalp. Guttate psoriasis has drop-shaped lesions. Pustular psoriasis presents as small, noninfectious, 1702:, when used as an emollient in psoriasis, has been found to decrease plaque clearance with phototherapy.
