Vitiligo is an acquired depigmentary skin disorder due to the loss of cutaneous melanocytes or alteration in melanocyte function, affecting over 0.5% of the world population. The exact cause of melanocyte loss in non-segmental vitiligo is still debatable, but many observations have pointed to the main role of cellular immunity. Earlier evidence has shown(More)
Psoriasis is a common chronic relapsing inflammatory cutaneous disease; the main role in the inflammation of this condition is played by lymphocyte Th1, Th17 and their cytokines. The activity of these cells is modulated by a particular kind of T cells recently described: the T regulatory cells (Treg). These are able to inhibit the immunological response and(More)
Anti-tumor necrosis factor (anti-TNF-alpha) are a group of new drugs able to inhibit the action of this cytokine. Although systemic side effects have been well described, cutaneous adverse reactions have not yet been clearly elucidated. The authors report a case of a 29-year-old man affected by Crohn disease and ankylosing spondylitis who developed(More)
Psoriasis is a chronic inflammatory disease associated with several comorbidities. Osteoporosis is defined as a reduction in bone mineral density with impaired bone microarchitecture. Several mechanisms may be implicated as a possible cause for the association between psoriasis and osteoporosis, such as systemic inflammation, anti-psoriatic drug intake and(More)
INTRODUCTION Psoriasis of the hands and feet is highly debilitating and difficult to treat. Lesions are very painfull, disabilitating and impair quality of life of patients. Most treatment options have limited efficacy, short duration of response and several adverse events. OBJECTIVE To investigate the safety and efficacy of Adalimumab in the management(More)
Erythrodermic psoriasis is a severe and disabling variant of psoriasis. The authors present the case of a 48-year-old man with psoriasis and hemophilia presented with a history of hepatitis C virus (HCV) infection treated with pegylated interferon alpha-2a and ribavirin therapy. At the end of antiviral therapy, skin manifestation progressively worsened,(More)
BACKGROUND Regulatory T-cells (T-reg) play a central role in the immunopathogenesis of psoriasis. T-reg cells are both functionally and numerically impaired in psoriasis and they are up-regulated by drug therapy. OBJECTIVE To analyse the circulating CD4+CD25 bright FOXP3+ subset in 14 patients with vulgaris/arthropathic psoriasis treated with biological(More)
