The rate of psoriasis in HIV-positive individuals is comparable to that of HIV-negative individuals, however, psoriasis tends to be more severe in people infected with HIV. 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 cellular signals from Th2 subset of CD4+ helper T cells, whereas the immune response in psoriasis vulgaris is characterized by a pattern of cellular signals typical of Th1 subset of CD4+ helper T cells and Th17 helper T cells. It is hypothesized that the diminished CD4+-T cell presence causes 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 of psoriasis and/or psoriatic arthritis.

Photodynamic Therapy Itching is one of the most common–and vexing–symptoms of scalp psoriasis, says Harold Farber, MD of Philadelphia. And itching begets inflammation and can cause your scalp psoriasis to spread to previously unaffected areas via the Koebner phenomenon. Scalp psoriasis tends to itch more than other body parts, and not scratching is easier said than done, Dr. Farber says. Making matters even more difficult, stress tends to travel with psoriasis and many of us cope with stress by … scratching. Scalp psoriasis treatments including OTC topical creams, gels, lotions, ointments, pads, shampoos, and sprays to help curb the itch. But “be careful applying these products to inflamed scales as they can burn or sting,” he says. Other anti-itch treatment options can include topical steroids and oral antihistamines.

Oral medications Anything that stresses your scalp can aggravate your psoriasis, Dr. Bagel says. “If you blow-dry your hair, make sure you don’t use the hottest setting.” Skipping the heat-shield step before applying a hot tool to your hair is among the worst hair care mistakes anyone can make. “Gently comb your hair, and not your scalp,” Dr. Bagel suggests. “Don’t pull at your hair which tugs at skin and can be source of trauma, causing psoriasis to worsen or spread.” Always tell your hair stylist that you have scalp psoriasis and let him or her know if you are sensitive to high heats, pulling, or rough scalp massages, the NPF suggests.
Most people with psoriasis go through “cycles” of symptoms. The condition may cause severe symptoms for a few days or weeks, and then the symptoms may clear up and be almost unnoticeable. Then, in a few weeks or if made worse by a common psoriasis trigger, the condition may flare up again. Sometimes, symptoms of psoriasis disappear completely.

FAQ Adam Friedman, the residency program director and director of translational research in the dermatology department at The George Washington University School of Medicine & Health Sciences, is a huge advocate of Denorex, as it contains coal tar to reduce inflammation and flakes, as well as provitamin B5 to strengthen the hair. His only warning is to be wary of shampoos containing coal tar, as they can be messy on stain towels and/or clothing. He also advises against using them if you're pregnant, as coal tar is supposedly teratogenic, which means it could be bad for developing babies.
To minimize the risk of nonadherence and poor clinical outcome, evidence-based treatment guidelines10 call for increased patient participation in treatment decision making to build a sense of active partnership and empower patients for greater self-management of the disease. One important step to achieve this goal is to assess the preferences that individuals have for the attributes of their therapy. Preferences is an economic concept referring to the value that an individual attaches to different options when presented with a choice. More commonly acknowledged in other fields, the role and potential impact of patients' preferences is being increasingly recognized in the health care sector.19 Previous studies20,21 in psoriasis have used time trade-off or standard gamble preference elicitation methods in which participants are asked their willingness to trade off future life years or accept a risk of immediate death in exchange for returning to full health. Studies also have assessed health state utilities in psoriasis and psoriatic arthritis using willingness-to-pay analyses, visual analog scales,20,22,23 the EuroQol-5 multiattribute health utility instrument,24 and, recently, conjoint analysis (CA).25-27
