BACKGROUND: Biological agents targeting IL-17 are very effective for clearing moderate to severe psoriasis. There is limited information regarding the frequency and pattern of psoriasis relapse upon treatment cessation. OBJECTIVE: To investigate the pattern of psoriasis recurrence in patients who were treated with brodalumab following Amgen's decision to stop the clinical program in June 2015. MATERIALS AND METHODS: Between June 2015 and March 2016, we constructed a retrospective multicenter cohort study including patients who were treated with brodalumab in Amgen's protocols after the abrupt interruption of the drug development program...

Pustular psoriasis (PP) is a group of inflammatory skin conditions characterized by infiltration of neutrophil granulocytes in the epidermis to such an extent that clinically visible sterile pustules develop. Because of clinical co-incidence, PP is currently grouped with psoriasis vulgaris (PV). However, PP and PV are phenotypically different, respond differently to treatments, and seem to be distinct on the genetic level. In contrast to PV, the phenotypes of PP are not well defined. Descriptions of each form of PP are discordant among standard dermatology textbooks [1-5], encumbering the collection of phenotypically well-matched groups of patients as well as clinical trials...

BACKGROUND: It has been reported that patients with psoriasis are at increased risk for developing lymphoma including cutaneous T cell lymphomas (CTCL). However, the comorbidity and the histopathologic correlation of psoriasis and Mycosis Fungoides (MF) have been less studied. OBJECTIVE: The objective of the current study was to investigate the relation between mycosis fungoides (MF) and psoriasis. METHODS: We retrospectively reviewed and reevaluated all MF cases diagnosed and followed in a 16 year period who carried both MF and psoriasis diagnoses...

BACKGROUND: Generalised pustular psoriasis (GPP) and acrodermatitis continua of Hallopeau (ACH) are chronic, relapsing variants of pustular psoriasis proven to be remarkably challenging to treat. Due to their uncommon presentation, there are few described cases in literature and scarce evidence for management. Further information is needed to help dermatologists formulate treatment plans for patients presenting with such diseases. CASE SUMMARY: We report the case of a 68-year-old man with a 3-year history of psoriasis presenting to our clinic with a severe breakout of GPP and associated ACH...

Although neutrophils are a histologic hallmark of psoriasis, it is unclear whether neutrophils are simply effector cells or drive pathogenesis. A recent psoriasis study with murine models evaluated various chemokines, lipids, and cytokines proposing that neutrophils are key players in positive feedback loops perpetuating the disease.(1) Additionally, when neutrophils are depleted in pustular psoriasis, the disease drastically improves.(2) There is mounting evidence supporting the use of neutrophil to lymphocyte ratio (NLR) as a marker of inflammation in active psoriasis...

OBJECTIVES: New interleukins (ILs), especially members of IL-1 and IL-12 families, have recently been reported to be involved in the development and regulation of autoimmune and inflammatory diseases. In this study, we aimed to explore the impact of these new ILs in psoriasis (Ps) and psoriatic arthritis (PsA). METHODS: Forty PsA patients, 20 Ps patients, and 20 healthy controls (HCs) were recruited. Blood samples were obtained for detecting the levels of ILs, IL-12/23p40, and tumor necrosis factor α (TNF-α)...

We report a case of a 25-year-old Chinese man with an exceptionally prolonged history of pustular psoriasis derived from inverse psoriasis who was unsatisfied with conventional treatment and was successfully treated with a single dose of infliximab without noticeable adverse effects. No recurrence or flaring was observed after 3 months of follow-up. This case illustrates that infliximab may be an effective and safe therapeutic option for patients with refractory pustular psoriasis derived from inverse psoriasis...

Important changes in the understanding and management of drug hypersensitivity reactions during the last years result from the increasing importance of biologics in medical practice, which differ in their spectrum of adverse drug reactions (ADRs) from the classical covalent drugs. With regard to covalent drugs, ampicillin and amoxicillin as well as clavulanic acid play an increasing role among ADRs to betalactam antibiotics. Fluoroquinolones are mainly the cause of anaphylactic and photosensitivity reactions...

Internalized stigma is the adoption of negative attitudes and stereotypes of the society regarding a person's illness. It causes decreased self-esteem and life-satisfaction, increased depression and suicidality, and difficulty in coping with the illness. The primary aim of this study was to investigate the internalized stigma state of psoriatic patients and to identify the factors influencing internalized stigma. The secondary aim was to identify the correlation of internalized stigma with quality of life and perceived health status...

Patients with 'deficiency of the interleukin-36 receptor antagonist' (DITRA), caused by mutation of the IL36RN gene, exhibit psoriatic phenotypes, typically generalised pustular psoriasis (GPP). We report a paediatric case with DITRA, whose cutaneous lesions varied from psoriasis vulgaris in infancy to annular pustular psoriasis with acute exacerbation to GPP at 13 years of age. Conventional systemic treatments for GPP, which include oral retinoids, cyclosporine and methotrexate, are controversial in paediatric cases, because of their adverse effects and uncertain long-time consequences...

BACKGROUND: Palmoplantar psoriasis has significant physical and emotional impact on patients and can be difficult to treat. OBJECTIVE: To evaluate the efficacy of ixekizumab in the treatment of patients with moderate-to-severe non-pustular palmoplantar involvement and moderate-to-severe plaque psoriasis. METHODS: In three phase 3, double-blind, placebo-controlled trials, patients with moderate-to-severe non-pustular plaque psoriasis (UNCOVER-1 (N=1296), UNCOVER-2 (N=1224), UNCOVER-3 (N=1346)) were randomised to subcutaneous 80 mg ixekizumab every 2 or 4 weeks (Q2W, Q4W), after a 160 mg starting dose, or placebo through week 12...

Erythrodermic psoriasis (EP) and generalized pustular psoriasis (GPP) are the most severe forms of psoriasis, resulting in significant morbidity and even mortality (1) . There are few evidence-based data on their treatment (2,3) . Secukinumab, a fully human anti-IL-17A monoclonal antibody, demonstrated strong efficacy in treating moderate to severe plaque-type psoriasis (4,5) . This article is protected by copyright.

BACKGROUND: CD39 and CD73 are two novel cell surface markers of CD25(high) Foxp3(+) regulatory T-cells (Tregs). Concordant expression of these two ectoenzymes not only discriminate Tregs from other cell populations, but also generates pericellular adenosine, which has been reported to suppress proliferation of activated T effector (Teff) cells. Because it is currently unclear whether human ectoenzymes (CD39/CD73) are involved in the impaired suppressive activity of Tregs in psoriasis, we examined the frequencies and phenotypes of CD39/CD73-expressing Tregs and related receptor adenosine receptor 2A (A2A R) in peripheral blood of patients with different types of psoriasis...
