Enstilar in Combination With Enbrel or Humira for Plaque Psoriasis
Psoriasis4 weeks of adjunctive therapy of Enstilar® QD followed by 12 weeks QOD to patients with 2-10% BSA who are receiving etanercept or adalimumab for at least 24 weeks
Anti-Carbamylated Protein Antibodies in Psoriatic Arthritis
PsoriasisArthritis1 moreAnti-carbamylated protein (anti-CarP) antibodies are present in approximately one-fourth of the patients who are seronegative for both rheumatoid factor and anti-citrullinated protein antibody and who may therefore have psoriatic arthritis. The investigators hypothesized that detection of anti-CarP antibodies in serum may be useful for diagnosis of psoriatic arthritis.
Exploring the Effects of IL-23 Inhibition by Risankizumab on Psoriasis Autoimmunity
PsoriasisApproximately 80 patients affected by moderate to severe psoriasis will be screened for the presence of LL37( and ADAMTSL5 autoreactive T-cells in their blood at Day 0. Patients whose lymphocytes reacted with proliferation to LL37 or ADAMTSL5 will receive SKYRIZI (Risakizumab) at Day 1, week 4, 16, 28, 40. LL37 and ADAMTSL5-specific T-cell responses will be evaluated at Day 0, week 16, week 28 and week 52. Each patient will be followed for 52 weeks.
Efficacy and Safety of Sorilux in Maintenance Treatment of Moderate Type Plaque Psoriasis
Plaque PsoriasisThe study seeks to show whether there is additional benefit of using Lexette and Sorilux in the beginning of the treatment, and then maintenance treatment of Sorilux alone in moderate plaque type psoriasis patients.

Cytokines and Vascular Inflammation in Psoriasis
Vascular InflammationPsoriasis1 morePsoriasis is an inflammatory disease involving the skin, the joints and the vascular compartment. The mechanisms linking inflammation in the skin and joints and in the vascular walls are poorly understood. One hypothesis for the increase in vascular inflammation observed in patients with psoriasis involves circulating pro-inflammatory cytokines. Patients with psoriasis have an increase in serum levels of tumor necrosis factor alpha (TNF-alpha), Interleukin-17 (IL-17), IL-22, IL-6 as well as a the chemokine S100A913. It is possible that one of those cytokines/chemokine induces vascular inflammation in the vascular compartment. The purpose of this cross sectional retrospective study is to highlight the correlation between vascular wall inflammation using 18F-2-fluoro-2-deoxy-D-glucose - Positron Emission Tomography (FDG-PET) fluorodeoxyglucose technology and pro-inflammatory cytokines/chemokine.
Skin Irritation of LEO 90100 Foam (Calcipotriol Hydrate Plus Betamethasone Dipropionate) in Healthy...
Psoriasis VulgarisThis trial is looking at whether the LEO 90100 foam causes irritation of the skin in healthy Japanese male adults without psoriasis. A single application of LEO 90100 foam and its vehicle will each be made to 2 body sites in 20 subjects.
Psoriatic Inflammation Markers Predictive of Response to Adalimumab
Psoriasis VulgarisThe objective is to compare the initial skin inflammatory transcriptomic profile of psoriatic patient responder to Adalimumab therapy (defined as the achievement of a Psoriasis Area and Severity Index 75 response at 16 weeks) with the transcriptomic profile of patient non-responder to Adalimumab therapy (defined as the non-achievement of a Psoriasis Area and Severity Index 50 response at 16 weeks) to identify differentially expressed genes in order to define predictive markers of response to the treatment.
Recirculating Memory T Cells in the Pathogenesis of Psoriatic Arthritis and Cutaneous Psoriasis...
PsoriasisPsoriatic ArthritisThe aim of the study is to investigate the link between pro-inflammatory T cells responses arising in the skin in patients with cutaneous psoriasis and those present in the joints of patients developing psoriatic arthritis. The study is based on the hypothesis that a fraction of T cells with memory phenotype can recirculate from the skin and relocalize at extracutaneous sites including enthesis or synovial tissue thus propagating the pro-inflammatory cycle. This could represent a pathogenic mechanism in the development of PsA. The main aim of the study is to define the phenotypic and functional differences of circulating T cells in patients cutaneous psoriasis, patients with psoriatic arthritis and in control group of healthy subject. To this end the investigators analyze the expression of cell surface markers of central memory (TCM), effector memory (TEM) and effector (Teff) cells, within this subsets the investigators evaluate the expression of chemokine receptors as well as skin and tissue homing molecules. There will be also an evaluation of the T cell polarization towards Th1/Tc1 or Th17/Tc17 phenotype by evaluating the cytokine expression profile. In selected patients with PsA the researchers analyze in parallel the phenotype and the cytokine profile of T cell subpopulations in peripheral blood and in synovial fluid, The results of this study could possibly allow to define distinctive features of circulating T cells in patients with PsA and to understand the link between circulating and synovial fluid T cells in patients with PsA.
