Psoriasis (Auckland, N.Z.)最新文献

Psoriasis may manifest as severe hyperkeratotic lesions resembling an oyster shell called ostraceous psoriasis (OP). This type of psoriasis is extremely rare and is often associated with psoriatic arthritis (PA). Cases of OP associated with PA in children have never been reported before. We reported a 9-year-old girl with hyperkeratotic lesions resembling an oyster shell all over the body accompanied with swelling on joints of both fingers, knee joints, and ankle. Histopathological examination supported the diagnosis of OP. The diagnosis of PA was established according to the Classification Criteria for Psoriatic Arthritis (CASPAR). Significant improvements of the skin lesions and joints involved were observed within 44 days after the beginning of treatment with cyclosporine and a combination of high potent topical steroid with emollient. OP associated with PA is uncommonly seen in children. High potent corticosteroid combined with emollient showed good result in skin improvement with low side effects. In addition, cyclosporine can be a good choice of systemic therapy for OP with PA in children.

The skin is at the interface between the body and its environment and is therefore at the center of adolescent concerns during this period of identity formation and increased awareness of body image issues, and stigmatization. Managing an adolescent with psoriasis involves managing the illness and the individual during their transition from being an older child to a young adult. In addition to ensuring that the patient adheres to treatments and is engaged with the therapeutic strategy, dermatologists may also need to manage issues linked to unspoken suffering or conflicts between the adolescent and their parents, who are often present during consultations. The impact of psoriasis on the social interactions, school life and sexuality of the patients, together with the influence of the internet and social networks, also have to be taken into account. In this review, we summarize the epidemiologic, clinical, and therapeutic data available on psoriasis in adolescents, and propose specific management strategies, adapted to the 21st century, for patients in this age group.

The use of biological therapy is now common practice in the treatment of immune-mediated inflammatory diseases (IMID). Currently, there are no guidelines related to the management of cytomegalovirus (CMV) infections or reactivation during therapy with biological agents. Furthermore, there is a lack of guidance on the management of asymptomatic patients with persistent positive immunoglobulin (Ig)M anti-CMV after an extended period and who have to undergo therapy with biological agents. We report the case of a patient in this situation for whom treatment with biological drugs for psoriasis was indicated. A good clinical response was obtained with secukinumab and maintained during 6 months of follow-up. No infectious disease or reactivation of CMV infection occurred. We suggest some possible guidelines for the management of such cases.

Background: A growing body of evidence links psoriasis to several metabolic disorders, but the causal relationship between psoriasis and nonalcoholic fatty liver disease (NAFLD) remains understudied.

Purpose: To measure the correlation between the severity of psoriasis and the degree of NAFLD.

Patients and methods: A cross-sectional study was conducted on adult patients with psoriasis in the Dermatovenereology Outpatient Clinic of Cipto Mangunkusumo Hospital from December 2017 through February 2018. Psoriasis severity (psoriasis area and severity index [PASI] and body surface area [BSA]) was recorded and compared with NAFLD degree measured by controlled attenuation parameter (CAP).

Results: A total of 36 subjects were enrolled with an average age of 49.08 years (±15.52 years). The proportions of mild, moderate, and severe psoriasis were 50%, 27.8%, and 22.2%, respectively. Median of PASI was 6.1 (2-38.4) and BSA was 7.5 (2-93). The proportion of NAFLD was 77.8%. The mean of the CAP score was 250.03±45.64. There was no statistically significant correlation between psoriasis severity based on PASI and CAP score (r = 0.258; p = 0.128). However, if the degree of psoriasis was based on BSA, a significant correlation was found (r = 0.382; p = 0.021). The body mass index (BMI) and abdominal circumference were significantly correlated with CAP score (r = 0.448, p = 0.006 and r = 0.485, p = 0.003, respectively).

Conclusion: Psoriasis extension correlates with NAFLD severity; further studies should assess in detail the effect of therapies on this pathophysiological link.

Background: Previously identified risk factors for psoriatic arthritis (PsA); nail dystrophy and scalp lesions are highly prevalent in patients with moderate-to-severe psoriasis. Therefore, these variables may not be useful as predictors for PsA in this population.

Objective: We assessed the predictive value of demographic and clinical characteristics for development of PsA in a cohort of patients with moderate-to-severe psoriasis, currently treated with biologics. Furthermore, we reported the incidence of new-onset PsA in this population and described the characteristics of patients that developed PsA during biologic treatment.

Methods: Demographics and treatment characteristics of psoriasis patients currently using biologic therapy were extracted from the BioCAPTURE database (n=427). Poisson regression was used to calculate incidence rates. Multivariable logistic regression was performed to identify factors independently associated with PsA onset. Patient and treatment characteristics of patients that developed PsA during biologic treatment were described.

Results: The incidence of PsA was 1.0 (95% CI 0.8-1.2) per 100 psoriasis-years. Except for a lower risk for PsA in male gender (OR 0.58, 95% CI 0.34-0.98, p-value 0.04), no clinical factors were significantly associated with an altered risk of developing PsA. During biologic therapy, 32 patients (9.4%) newly developed PsA. In this group, 53.8% had PASI<5 at PsA diagnosis. The incidence rate of PsA was 1.6 (95% CI 1.1-2.2) per 100 years on biologic therapy.

Conclusion: Clinical risk factors might be inaccurate to predict PsA onset in patients with moderate-to-severe psoriasis on biologics. Even with low disease activity, psoriasis patients on biologics are still prone to develop PsA.

Purpose: Dermatologists practicing in African and Middle Eastern countries face numerous challenges when managing patients with plaque psoriasis, especially those with disease in a difficult-to-treat anatomic area or those who are a pediatric, geriatric, or pregnant patient. The publication of comprehensive, up-to-date, region-specific clinical guidelines may help to address some of these challenges and improve outcomes. We conducted a literature review to identify recent guidelines and other publications describing patients with plaque psoriasis in Africa and the Middle East.

Patients and methods: An online literature search of the PubMed database was conducted to identify publications reporting clinical guidelines and research studies on plaque psoriasis. The search included all articles published from January 2008 to March 2020 inclusive. The titles and abstracts of all search results were screened by a reader to identify those that described patients in Africa or the Middle East.

Results: A total of 145 publications were identified by the literature search and screened by a reader. There were 10 publications that described patients in Africa or the Middle East: 4 research articles, 3 reviews, 2 guidelines, and 1 case study. The 2010 guidelines from South Africa made recommendations for treating plaque psoriasis of varying severity, although without specific recommendations for difficult-to-treat anatomic areas or pediatric, geriatric, or pregnant patients. The 2014 guideline on biologics from Saudi Arabia included recommendations for the use of these agents in patients with plaque psoriasis, including difficult-to-treat anatomic areas and pediatric patients (TNF inhibitors only), but provided no recommendations for pregnant or geriatric patients.

Conclusion: There is an urgent unmet need for comprehensive clinical guidelines on the management of patients with plaque psoriasis in Africa and the Middle East. Region-specific studies on the epidemiology, burden of disease, and the safety and effectiveness of newer pharmacotherapies are needed to support the development of such guidelines.

Background: Cell lesion and apoptosis with release of cell-free DNA (CFD) in circulation are associated with chronic inflammation of psoriasis.

Objective: The objective of this study was to determine the CFD concentrations in sera of patients with psoriasis, to assess its relationship with disease severity as defined by Psoriasis Area Severity Index (PASI) and other inflammatory biomarkers (C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR)) levels, and to monitor the efficacy of treatment.

Patients and methods: Thirty adult patients with different types of psoriasis (25 vulgaris; 10 mild, 15 moderate and 5 erythroderma; severe) were evaluated during the exacerbation phase of the disease, before starting (T0) and after 12 weeks (T12) of treatment with topical therapy for mild cases, narrowband-ultraviolet light B (NB-UVB) for moderate cases and methotrexate for severe cases. Twenty healthy controls were also involved in the study. The concentrations of CFD in sera were measured before and after treatment by quantitative real time PCR (qPCR) using primers of the human β-globin gene.

Results: At T0, all patients presented significant higher levels of ESR (P=0.05) and CFD (P=0.001) compared with controls. Highly significant elevations of all parameters were observed in severe disease (erythroderma) compared to mild/moderate disease (vulgaris). Methotrexate treatment induced highly significant reductions in all inflammatory markers including CFD (P= 0.042) while topical and UV irradiation therapies had no effects. CFD concentrations showed positive correlations with both PASI (r=0.422, P=0.020) and ESR (r=0.321, P=0.023) only before the start of treatment.

Conclusion: The level of circulating CFD could be used to monitor psoriasis severity. However, its level cannot be stated for the treatment, except in severe erythrodermic patients upon successful treatment with methotrexate. We recommend validation of a convenient and accurate DNA assay applied directly to biological samples which does not require prior DNA extraction and amplification.

Background: Dimethyl fumarate (DMF) has an inhibitory effect on the production of pro-inflammatory proteins from different cells which participate in the immune reaction in psoriatic skin. Most recently it was shown that DMF is an allosteric covalent inhibitor of the p90 ribosomal S6 kinases (RSK1, 2), determined by X-ray crystallography. DMF binds to a specific cysteine residue in RSK2 and in the closely related mitogen and stress-activated kinases 1 (MSK1) which inhibits further downstream activation.

Objectives: The aim of this study was to review the literature on the effects of DMF on activation of MSK1, RSK1, 2 kinases, and downstream transcription factors NF-κB/p65 and IκBα in cells contributing to the pathogenesis of psoriasis. We also hypothesized and studied if treatment with DMF would inhibit the activation of MSK1, RSK1, 2 kinases in peripheral blood mononuclear cells (PBMCs) in psoriatic patients.

Methods: PBMCs were purified from patients with severe psoriasis before and after 90 days of treatment with DMF. Cells were stimulated with anisomycin, IL-1β or EGF for 10 and 20 minutes. The levels of phosphorylation of MSK1, RSK1, 2 or NF-κB/p65, IκBα were analyzed by Western blotting.

Results: Our case study showed that treatment with DMF inhibited the activation of MSK1 and RSK1, 2 kinases in PBMCs in patients. This supports that DMF is the active metabolite in vivo in psoriatic patients during DMF treatment.

Conclusion: Pro-inflammatory proteins are induced through activation of MSK1 and NF-κB/p65 at (S276). The extracellular signal-regulated kinases (ERK1/2) control cell survival by activating both MSK1 and RSK1, 2 kinases. P-RSK1, 2 activates P-κBα and NF-κB/p65 at (S536). The phosphorylation of NF-κB/p65 at (S276) and (S536) controls different T cell and dendritic cell functions. DMF´s inhibitory effect on MSK1 and RSK1, 2 kinase activations reduces multiple immune reactions in psoriatic patients.

Tofacitinib is an oral Janus kinase inhibitor approved for the treatment of psoriatic arthritis (PsA). It provides an alternative option for patients who have had an inadequate response and tolerance to other disease modifying antirheumatic drugs (DMARDs). It has demonstrated comparable efficacy to biologics, is effective in the management of treatment resistant disease, and is reported to improve enthesitis, dactylitis, and radiographic progression. Tofacitinib is also associated with an increased risk of serious infections, malignancy, and laboratory abnormalities. There is currently a large armamentarium of therapies for psoriatic arthritis, and choosing among treatments can be challenging. Due to this wide selection, a thorough assessment of psoriatic disease phenotype, patient preference, disease presentation, and comorbidities is critical. This review addresses key considerations in patient selection for the treatment of PsA with tofacitinib.

Plaque psoriasis (PsO) is a chronic inflammatory skin disorder that may be associated with several comorbidities, including arthritis. The increasing knowledge of psoriasis pathogenesis led to the identification of novel targeted therapeutic interventions. Among them, anti-IL-17A and anti-IL-17F antibodies are currently being investigated for the treatment of PsO and/or psoriatic arthritis (PsA). Bimekizumab is one of these agents, capable ofsimultaneously neutralizing both IL-17A and IL-17F cytokines. In this review we included preclinical and clinical data related to this highly promising agent that shows a peculiar molecular structure differing from other bispecific agents.
