Infliximab is a monoclonal antibody that targets tumor necrosis factor-alpha (TNFalpha). It is used in the treatment of a number of inflammatory disorders including severe plaque psoriasis. TNFalpha is thought to have a major role in psoriasis by promoting an inflammatory infiltrate into the skin and inducing keratinocyte proliferation and preventing keratinocyte apoptosis, which directly contr...

BACKGROUND Recent studies into the pathogenesis of psoriasis have identified the importance of interleukin 17 (IL-17) in disease activity and have thus provided a new target for biologic therapy. Ixekizumab, the most recent US Food and Drug Administration (FDA)-approved anti-IL-17 biologic agent, appears to be a promising medication for patients suffering from moderate-to-severe plaque psoriasi...

Guttate psoriasis (GP) typically occurs following an acute infection such as streptococcal pharyngitis. It is thought to have a better prognosis than chronic plaque psoriasis (PP). This retrospective cohort study of 79 patients with GP aims to assess the likelihood of developing PP after the first episode of GP as well as compare clinical and laboratory data in patients with GP who do and do no...

BACKGROUND The Randomized Controlled Evaluation of Adalimumab in Treatment of Chronic Plaque Psoriasis of the Hands and Feet (REACH) trial demonstrated that adalimumab was efficacious and well-tolerated for the treatment of hand and/or foot psoriasis through 28 weeks. OBJECTIVE To evaluate the effects of patient baseline characteristics on efficacy of adalimumab treatment of hand and/or foot ...

Background and Aim: This study aimed to assess the effects of zinc supplementation on the clinical signs of patients with plaque-type psoriasis with skin congestion under 20%. Materials and Methods: This randomized double-blinded clinical trial included 44 patients with plaque-type psoriasis with skin congestion under 20% referring to the Imam Reza Hospital in Ardabil, Iran. The patients with ...

BACKGROUND The influence of streptococcal infections in the pathogenesis of psoriasis is not yet understood. In vitro data suggest that streptococcal factors influence T-cell function in psoriasis in a HLA-dependent manner, but studies designed to measure the HLA-C/Streptococci interaction are lacking. In the present study, we hypothesized that there is a statistical interaction between the res...

Chronic plaque psoriasis, the most common form of psoriasis, is a papulosquamous disease defined by erythematous plaques with a silvery scale. The diagnosis usually is clinical, but occasionally a biopsy is necessary. Psoriasis affects 0.6 to 4.8 percent of the U.S. population, and about 30 percent of affected patients have a first-degree relative with the disease. Psoriasis is a T-cell-mediate...

Background: T cell activation is discussed as an important factor in the pathogenesis of psoriasis. Recently, a lot of attention has been paid to the role of superantigens in T cell activation in the pathogenesis of psoriasis. In this study, the role of staphylococcal superantigens in the pathogenesis of psoriasis with identification of staphylococcal toxin levels in the skin lesions of patient...

Psoriasis is a chronic and recurrent dermatitis, mediated by keratinocytes and T cells. Several proinflammatory cytokines contribute to formation and maintenance of psoriatic plaque. The Th1/Th17 pathways and some of IL-1 family members were involved in psoriasis pathogenesis and could contribute to disease activity. Therefore, we sought to analyse skin transcript levels of IL17A, IL22, RORC, I...

Background: Psoriasis is a common inflammatory skin disorder. There has been considerable interest in herbal medicine as a treatment for psoriasis. In a previous study HESA-A, a marine-herbal drug, was found to be beneficial in the treatment of psoriasis vulgaris. The aim of this study was to assess the efficacy and tolerability of HESA-A in patients with psoriasis. Methods: Nineteen patients w...
