Psoriasis

The umbrella term psoriasis is now understood to incorporate several distinct phenotypes or endotypes along the disease spectrum that in turn will dictate different therapies. A stratified medicine approach to psoriasis using this clinical information coupled with pharmacogenomic and immunologic data will become more widely acceptable in the future. Comorbidities associated with psoriasis, such as diabetes, depression, and Crohn disease, and the debate about the interdependence of psoriasis and cardiovascular disease will also dictate future research and holistic and management plans for this complex disease...

BACKGROUND: Citation analysis is an effective way to gauge the impact of an article on the scientific community. OBJECTIVE: The purpose of this study was to perform a citation analysis of 24 clinical dermatologic journals from 1970 to 2012, limited to the topic of psoriasis. METHODS: The authors conducted a search of "psoriasis" in the Science Citation Index from 1970 to 2012, including articles that have received 100 or more citations. The top 100 most cited articles were further analyzed for country, institution, and study type...

Psoriasis is a chronic inflammatory skin disorder, which is associated with a significant negative impact on a patient's quality of life. Traditional therapies for psoriasis are often not able to meet desired treatment goals, and high-dose and/or long-term use is associated with toxicities that can result in end-organ damage. An improved understanding of the involvement of cytokines in the etiology of psoriasis has led to the development of biologic agents targeting tumor necrosis factor (TNF)-α and interleukins (ILs)-12/23...

Tumor necrosis factor alpha (TNF-α) is a cytokine that plays a critical role in inflammatory and immune processes and in the control of infections and sepsis. Data on the perioperative management of patients treated with biologic drugs are limited and mainly in patients with rheumatoid arthritis (RA) and inflammatory bowel disease (IBD). This retrospective study assesses variations in the incidence of side effects between psoriatic patients who temporarily discontinue or continue biological therapy before surgical treatment...

INTRODUCTION: Psoriasis affects about 1-2% of the entire population. Due to its chronicity and relapsing course, psoriasis has a great influence on patients' quality of life and psychological status. AIM: To evaluate apprehensaion of the disease by psoriatic patients. MATERIAL AND METHODS: One hundred psoriasis patients (36 females, 64 males; mean age 47.3 ±15.8 years) were enrolled. Mean psoriasis severity assessed according to PASI was 17...

BACKGROUND: The nationwide prevalence of latent tuberculosis infection (LTBI) in Italian patients with psoriasis has never been investigated. OBJECTIVES: To estimate the nationwide prevalence of LTBI in Italian patients with psoriasis who are candidates for systemic treatment. METHODS: Data were obtained from the Psocare Registry on those patients (n = 4946) with age > 18 years, systemic treatment at entry specified and tuberculin skin test (TST) performed according to the Mantoux method...

In 2009, GRAPPA published their first evidence-based recommendations for the treatment of psoriasis and psoriatic arthritis (PsA). Since then, new information has been published and drugs developed. We summarize evidence for the efficacy of available treatments for peripheral joint involvement in PsA. We performed a systematic review of current literature on the efficacy of different therapies, management, and therapeutic strategies for peripheral arthritis involvement in PsA, in order to provide information for the development of the new GRAPPA treatment recommendations...

Axial involvement in patients with psoriatic arthritis (PsA) remains common and can be defined in terms of spinal disease alone or in combination with peripheral manifestations. Diagnosis is based upon inflammatory spinal symptoms or the presence of radiological sacroiliitis and other radiographic signs of spondylitis, or by criteria for axial spondyloarthritis (SpA) defined by ASAS (Assessment of SpondyloArthritis International Society). Although recent data are scarce for efficacy of traditional therapies for axial disease (e...

INTRODUCTION: Psoriatic arthritis is a common and often severe chronic joint disorder associated with the skin disease psoriasis (PsO). Treatment options for psoriatic arthritis patients have changed considerably over the last decade with the widespread use of biological therapies, in particular tumour necrosis factor inhibitors. Current clinical experience based on large registries and careful observations now allows us to understand the true value of these interventions in daily clinical practice...

BACKGROUND: Multiple biological therapies are approved for the treatment of moderate-to-severe psoriasis. OBJECTIVES: To assess the short-term efficacy of biological treatments for moderate-to-severe psoriasis via a network meta-analysis that adjusts for reference arm response rates. METHODS: Fifteen randomized trials of biological treatments for moderate-to-severe psoriasis were identified. Rates of response, assessed as 50%, 75% and 90% reductions in the Psoriasis Area and Severity Index (PASI), were compared using a network meta-analysis...

INTRODUCTION: Psoriasis is a chronic inflammatory disease associated with an increased risk of ischemic coronary artery disease (CAD) in some populations. We aimed to determine the association between these 2 diseases in our geographic area. MATERIAL AND METHOD: We performed a cross-sectional study of patient records between 2005 and 2012 in the database (Abucacis, Datamart) that contains all medical case histories in the province of Castellón, Spain. Patients diagnosed with psoriasis were compared with a control group of patients diagnosed with melanocytic nevus...

Psoriasis is a common inflammatory dermatosis that may be seen in infants, children, and adolescents. The clinical presentation and course may be quite variable, and while patients with mild disease are often easily managed, those with recalcitrant or more severe disease often present a therapeutic dilemma given the number of therapies available and the relative lack of data on the efficacy and safety of use of these therapies in children. Diagnosis in children can be more difficult, but family history may be helpful...

Background:Although the occurrence of psoriasis and vitiligo is reported in a few studies, no proper relationship has been found between these two diseases.Objective:The aim of this study was to identify the frequency of the coincidence of these two diseases.Method:A descriptive and cross-sectional study was conducted on 6,200 patients referred to dermatology clinics from September 2004 to June 2005.Results:Among these patients, 219 and 154 patients suffered from psoriasis (3.53%) and vitiligo (2.48%), respectively, and 12 patients (0...

The biologic agents vary considerably in terms of their long-term duration of effect. Using the definitions provided by the National Psoriasis Foundation Medical Board, the objective of this review was to compare all biologic agents with respect to time to relapse and potential for rebound. Overall, alefacept had the longest off-treatment benefit (29.9 weeks in Psoriasis Area and Severity Index [PASI] 75 responders), followed by ustekinumab (22 weeks), infliximab (19.5 weeks), adalimumab (18 weeks), etanercept (12...

Psoriatic arthritis is a major comorbidity of psoriasis that significantly impairs quality of life and physical function. Because skin lesions classically precede joint symptoms, dermatologists are in a unique position to identify patients at risk for psoriatic arthritis before irreversible joint damage occurs. Here we review the literature to identify the clinical and genetic factors most highly associated with development of psoriatic arthritis, with the goal of assisting dermatologists in risk-stratifying their psoriasis patients...

The concept that psoriasis is an autoimmune disease needs to be questioned. The autoimmune label has been based on molecular mimicry between streptococcal and keratin proteins and the existence of homologous peptides between these proteins. However, it is only peripheral blood CD8, and not CD4, T lymphocytes that respond to the homologous peptides. This ignores the fact that it is CD4 T cells which are necessary to initiate psoriasis. Recent studies on skin bacterial microbiota have found a variety of bacteria in both normal skin and psoriatic lesions...

IMPORTANCE: Combined use of systemic agents may be necessary to achieve disease control in therapy-resistant patients. However, to our knowledge, an overview of evidence, including quality assessments, is not yet available, and no guidance on monitoring, contraindications, and interactions exists. OBJECTIVES: To summarize and critically appraise the evidence on efficacy and safety of combination therapy with systemic agents in plaque-type psoriasis. EVIDENCE REVIEW: Through March 2013, an electronic search limited to randomized clinical trials was performed in MEDLINE, EMBASE, The Cochrane Library, and ongoing trial registers...

Recently, thiazolidinediones have shown to be efficacious with a favorable safety profile when used in the treatment of chronic plaque-type psoriasis. The aim of this study was to evaluate and compare the efficacy and safety of a combination of methotrexate plus pioglitazone and methotrexate alone in plaque-type psoriasis. A total of 44 adult patients with plaque-type psoriasis were included in the study. Patients were randomized to treatment with methotrexate alone (group A) or methotrexate plus pioglitazone (group B) for 16 weeks...
