This multicenter study aimed to develop and validate a novel multidimensional scoring system addressing this clinical gap.<h4>Methods</h4>Under the guidance of the Shenzhen Psoriasis Academy, we conducted seven expert meetings to analyze existing evidence from PubMed, Wanfang, and CNKI databases. Through iterative Delphi consensus processes involving 26 specialists across 10 disciplines, we established the Psoriasis Disease Assessment Index (PSODAI). This 60-point composite instrument evaluates cutaneous involvement and nine key organ/system comorbidities. An accompanying online calculator (http://www.psodai.com.cn/) was developed for clinical implementation. Validation involved 254 psoriasis patients from six tertiary centers, with comparative analyses against PASI and DLQI metrics.<h4>Results</h4>The PSODAI framework stratifies disease severity as mild (0-20), moderate (21-40), and severe (41-60). Comparative analysis revealed comparable proportions of moderate-to-severe cases between PSODAI and conventional tools (PASI/DLQI) (p&gt;0.05). Notably, 11 patients (4.3%) classified as severe by PASI were re-categorized as mild through PSODAI's systemic evaluation, primarily due to limited extracutaneous manifestations.<h4>Conclusion</h4>As the first comorbidity-integrated assessment tool, PSODAI enables cross-specialty collaboration for holistic patient management. Its clinical adoption may facilitate timely comorbidity detection and preventive interventions. Further multicenter validation is warranted to confirm these preliminary findings.<p><a href="http://europepmc.org/article/MED/41737997?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">483</guid><pubDate>Thu, 26 Feb 2026 07:51:29 +0000</pubDate></item><item><title>On-label persistence in psoriasis after switching to guselkumab, tumor necrosis factor inhibitors, interleukin-17 inhibitors, or apremilast from other advanced therapies.</title><link>https://www.psoriasis-news.de/articles.html/1_articles/on-label-persistence-in-psoriasis-after-switching-to-guselkumab-tumor-necrosis-factor-inhibitors-interleukin-17-inhibitors-or-apremilast-from-other-advanced-therapies-r482/</link><description><![CDATA[<h4>Objective</h4>To compare on-label persistence among adults with psoriasis who switched from other advanced therapies to guselkumab versus subcutaneous tumor necrosis factor inhibitors (SC TNFi), subcutaneous interleukin-17 inhibitors (SC IL-17i), or apremilast.<h4>Materials and methods</h4>This retrospective cohort study used U.S. claims data from the IQVIA PharMetrics<span class="ipsEmoji">®</span> Plus database (2016- 2023). Overlap propensity score weights were used to balance cohorts on baseline characteristics. On-label persistence was defined as the absence of drug discontinuation (event) and any dose change relative to the U.S. label (censoring). Survival analyses were used to assess on-label persistence from the start of the maintenance phase.<h4>Results</h4>At 12, 18, and 24 months after the start of the maintenance phase, respectively, on-label persistence was 190%, 180%, and 179% more likely on guselkumab versus SC TNFi; 78%, 87%, and 91% more likely on guselkumab versus SC IL-17i; and 187%, 199%, and 193% more likely on guselkumab versus apremilast (all <i>p</i> &lt; 0.001).<h4>Conclusions</h4>Patients experiencing suboptimal outcomes with other psoriasis-indicated advanced therapies achieved higher on-label persistence after switching to guselkumab, raising the potential for improved disease control relative to other treatment options.<p><a href="http://europepmc.org/article/MED/41732098?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">482</guid><pubDate>Thu, 26 Feb 2026 07:51:29 +0000</pubDate></item><item><title>Activation of NF-&#x3BA;B signaling in tissue-resident memory T cells promotes recurrent psoriasis in mice</title><link>https://www.psoriasis-news.de/articles.html/1_articles/activation-of-nf-%CE%BAb-signaling-in-tissue-resident-memory-t-cells-promotes-recurrent-psoriasis-in-mice-r481/</link><description><![CDATA[<small>No abstract supplied.</small><p><a href="http://europepmc.org/article/PMC/PMC12926151?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">481</guid><pubDate>Thu, 26 Feb 2026 07:51:29 +0000</pubDate></item><item><title>Toward the definition of moderate psoriasis: an expert opinion.</title><link>https://www.psoriasis-news.de/articles.html/1_articles/toward-the-definition-of-moderate-psoriasis-an-expert-opinion-r480/</link><description><![CDATA[<h4>Background</h4>The clinical definition of moderate psoriasis is debated, affecting treatment eligibility and patient outcomes.<h4>Objective</h4>A panel of Italian dermatologists aimed to propose practical criteria to define moderate psoriasis, based on a comprehensive literature review and clinical experience.<h4>Methods</h4>The panel reviewed publications between 2016 and 2024 focusing on key severity scores, including the Psoriasis Area and Severity Index (PASI), Body Surface Area (BSA), Dermatology Life Quality Index (DLQI), and Physician's Global Assessment (PGA), along with special area involvement and patient-reported outcomes.<h4>Results</h4>Despite variability among studies, and the lack of universally accepted thresholds, the panel defined moderate psoriasis as a BSA of 5%-10%, DLQI of 5-10, a PGA score of 3, and involvement of at least two special areas (e.g. scalp, face, genitals, nails, hands, or feet). Distressing itch and psychosocial impact were also recognized as critical elements influencing perceived disease burden. A composite PGA-based approach, integrating objective measures with patient-centered criteria, is proposed for identifying patients with moderate psoriasis who may benefit from systemic therapy.<h4>Conclusion</h4>This pragmatic approach may help bridge the gap between guidelines and real-world clinical practice, ensuring more accurate treatment allocation and reducing undertreatment of psoriasis.<p><a href="http://europepmc.org/article/MED/41725608?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">480</guid><pubDate>Thu, 26 Feb 2026 07:51:29 +0000</pubDate></item><item><title>Perceptions over biologics for psoriasis after 5 years of access in Brazil: a cross-sectional study.</title><link>https://www.psoriasis-news.de/articles.html/1_articles/perceptions-over-biologics-for-psoriasis-after-5-years-of-access-in-brazil-a-cross-sectional-study-r479/</link><description><![CDATA[<h4>Background</h4>Biologic therapies have transformed psoriasis management, and their incorporation into Brazil's public healthcare system (SUS) in 2019 expanded access nationwide. However, real-world utilization and perceptions remain incompletely understood.<h4>Objectives</h4>To evaluate perceptions, barriers, and prescription patterns regarding biologic therapy among Brazilian dermatologists and patients five years after universal incorporation, while quantifying the prevalence of undertreatment.<h4>Methods</h4>We conducted two independent cross-sectional online surveys throughout 2024 among dermatologists (<i>n</i> = 225) and patients with psoriasis or psoriatic arthritis (<i>n</i> = 1,001). Data on demographics, clinical characteristics, and perceived barriers were analyzed.<h4>Results</h4>Overall, 64.9% of dermatologists prescribed biologics, with higher prescribing rates among younger physicians (<i>p</i> = 0.022), those with fewer years of practice (<i>p</i> = 0.013), higher patient volumes (<i>p</i> &lt; 0.001), and practice in tertiary centers (<i>p</i> = 0.001). Only 25.5% of patients were receiving biologics, strongly associated with psoriatic arthritis (<i>p</i> &lt; 0.001), with no difference between public and private care. Key barriers included perceptions that conventional therapies are sufficient (59.5%), insufficient training (38.0%), and administrative burden (45.5%), while patients mainly reported safety (45.7%) and cost (30.9%) concerns. Undertreatment was prevalent, affecting over 50% of patients with moderate-to-severe disease. While 71.3% of non-users were willing to start biologics, only 28.0% had received a medical recommendation.<h4>Conclusions</h4>Persistent educational and structural barriers continue to limit optimal biologic use despite formal availability, highlighting the need for targeted education, streamlined care pathways, and improved physician-patient communication to achieve equitable outcomes.<p><a href="http://europepmc.org/article/MED/41738157?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">479</guid><pubDate>Thu, 26 Feb 2026 07:51:29 +0000</pubDate></item><item><title>Cardiovascular Risk in Psoriasis Compared With Atopic Dermatitis: The Shizuoka Kokuho Database.</title><link>https://www.psoriasis-news.de/articles.html/1_articles/cardiovascular-risk-in-psoriasis-compared-with-atopic-dermatitis-the-shizuoka-kokuho-database-r478/</link><description><![CDATA[Psoriasis is a chronic inflammatory skin disease, and previous studies among Western populations have suggested an increased risk of cardiovascular events in patients with psoriasis. However, evidence from Asian populations remains limited. We evaluated the risk of major adverse cardiovascular events (MACE) in patients with psoriasis compared with patients who have atopic dermatitis (AD) using a large-scale administrative claims database from Shizuoka, Japan. We conducted a cohort study using the Shizuoka Kokuho Database, including patients aged ≥ 40 years who were newly diagnosed with psoriasis or AD between April 2012 and September 2022. Propensity score matching was used to balance age, sex, and baseline cardiovascular risk factors. The primary outcome was hospitalization for MACE, defined as myocardial infarction (MI) or stroke. Survival analyses were conducted, treating death as a competing risk. After 1:1 propensity score matching (n = 2208 per group), the mean age was 70 years. During a follow-up period (median 4.5 years for psoriasis and 4.4 years for AD), the incidence of MACE was 2.7% in both groups (hazard ratio 0.96, 95% confidence interval 0.67-1.38; p = 0.84). When analyzed separately, the risks of MI and stroke did not differ significantly between groups. Results were consistent across subgroups by psoriasis severity and in two sensitivity analyses. We observed no excess risk of MACE in Japanese patients with psoriasis compared with those with AD over a median follow-up of approximately 4.5 years. These findings suggest that the cardiovascular risk specifically attributable to psoriasis may be limited in the Japanese population.<p><a href="http://europepmc.org/article/MED/41738586?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">478</guid><pubDate>Thu, 26 Feb 2026 07:51:29 +0000</pubDate></item><item><title>The Association Between the Aggregate Index of Systemic Inflammation (AISI) and Prevalence of Psoriasis: Cross Sectional NHANES Study 2003-2006 and 2009-2014.</title><link>https://www.psoriasis-news.de/articles.html/1_articles/the-association-between-the-aggregate-index-of-systemic-inflammation-aisi-and-prevalence-of-psoriasis-cross-sectional-nhanes-study-2003-2006-and-2009-2014-r477/</link><description><![CDATA[The aggregate index of systemic inflammation (AISI), calculated from monocyte, neutrophil, lymphocyte, and platelet counts, is a blood-count-derived composite marker of systemic inflammation. This cross-sectional study aimed to examine the association between AISI and the prevalence of psoriasis among U.S. adults. The dataset was obtained from the National Health and Nutrition Examination Survey (NHANES) database from 2003 to 2006 and from 2009 to 2014. The relevant covariates were adjusted during the analysis. We employed restricted cubic spline (RCS) regression and logistic regression frameworks to statistically assess the correlation between the AISI standard and psoriasis. The study also included subgroup analyses to determine whether the effectiveness of AISI varied among different categories. Compared with individuals without psoriasis, participants with psoriasis had higher AISI values. A total of 17 776 participants were included in the analysis. In multivariable logistic regression analyses, higher AISI levels were independently associated with higher odds of prevalent psoriasis after adjustment for potential confounders (p for trend &lt; 0.001). Restricted cubic spline analyses demonstrated an approximately linear positive association between ln-transformed AISI and psoriasis prevalence (p for non-linearity &gt; 0.05). Subgroup analyses showed no statistically significant interactions across most strata, suggesting overall consistency of the association. Receiver operating characteristic analysis indicated that AISI had limited discriminatory ability for prevalent psoriasis, with an AUC (95% CI) of 0.58 (0.55-0.60). In this large, population-based cross-sectional study, higher AISI levels were associated with the prevalence of psoriasis among U.S. adults. Given the cross-sectional design and the modest discriminatory ability (AUC = 0.58), AISI is best interpreted as a correlate of systemic inflammation rather than as a marker with predictive or causal utility for psoriasis.<p><a href="http://europepmc.org/article/MED/41732102?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">477</guid><pubDate>Thu, 26 Feb 2026 07:51:29 +0000</pubDate></item><item><title>Coexistence of MOG-IgG-associated bilateral optic neuritis with psoriasis vulgaris and psoriatic arthritis in an Asian patient: a rare case report.</title><link>https://www.psoriasis-news.de/articles.html/1_articles/coexistence-of-mog-igg-associated-bilateral-optic-neuritis-with-psoriasis-vulgaris-and-psoriatic-arthritis-in-an-asian-patient-a-rare-case-report-r476/</link><description><![CDATA[<small>No abstract supplied.</small><p><a href="http://europepmc.org/article/MED/41723419?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">476</guid><pubDate>Mon, 23 Feb 2026 12:03:16 +0000</pubDate></item><item><title>Targeting the IL-36 Pathway: Spesolimab as a Therapeutic for Acute Flares of Pustular Psoriasis</title><link>https://www.psoriasis-news.de/articles.html/1_articles/targeting-the-il-36-pathway-spesolimab-as-a-therapeutic-for-acute-flares-of-pustular-psoriasis-r475/</link><description><![CDATA[<small>No abstract supplied.</small><p><a href="http://europepmc.org/article/PMC/PMC12925328?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">475</guid><pubDate>Mon, 23 Feb 2026 12:03:16 +0000</pubDate></item><item><title>Effectiveness and Safety of Roflumilast in the Treatment of Psoriasis: A Systematic Review and Meta-Analysis...</title><link>https://www.psoriasis-news.de/articles.html/1_articles/effectiveness-and-safety-of-roflumilast-in-the-treatment-of-psoriasis-a-systematic-review-and-meta-analysis-r474/</link><description><![CDATA[<h4>Background</h4>Psoriasis, a chronic autoimmune condition, can severely impact patients' well-being. It is characterized by erythema, thickening, and scaling of the skin. Plaque psoriasis, the most prevalent type, affects 80%-90% of psoriasis patients, ranging from localized to severe cases. Although corticosteroids are commonly used to treat psoriasis, prolonged use poses risks. Therefore, alternative therapies are needed. Roflumilast, a potent phosphodiesterase 4 inhibitor, is currently being considered as a treatment for plaque psoriasis.<h4>Methods</h4>We searched four electronic databases (Cochrane Central Register of Controlled Trials, PubMed, Scopus, and Web of Science) up to March 2024 for relevant articles evaluating the efficacy and tolerability of roflumilast in the management of psoriasis. The quality of evidence from trials was assessed using the Cochrane Risk of Bias tool (RoB1). Data from the included studies were extracted into a standardized online sheet and analyzed using RevMan 5.4.<h4>Results</h4>Roflumilast significantly increased the proportion of patients achieving an Investigator's Global Assessment score of 0 or 1 and a 2-point improvement score at both weeks 4 and 8 compared to placebo (RR = 3.48, 95% CI [2.04 to 5.92], P &lt; 0.00001, and RR = 4.02, 95% CI [3.17 to 5.11], P &lt; 0.00001, respectively). The pooled studies demonstrated homogeneity at both weeks 4 (P = 0.17, I² = 38%) and 8 (P = 0.38, I² = 5%). Regarding the results of the Psoriasis Area and Severity Index, 75% favored roflumilast over placebo (RR = 2.72, 95% CI [1.18 to 6.28], P &lt; 0.00001, and RR = 3.41, 95% CI [2.19 to 5.32], P &lt; 0.00001, at weeks 4 and 8, respectively). Subgroup analysis addressed the observed heterogeneity in the results.<h4>Conclusion</h4>This meta-analysis represents the first investigation into the efficacy and safety of roflumilast for treating psoriasis. Results suggest that roflumilast is both effective and well-tolerated in managing psoriasis. However, additional robust clinical trials are needed to validate these observations..<p><a href="http://europepmc.org/article/MED/41691689?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">474</guid><pubDate>Sun, 22 Feb 2026 17:52:44 +0000</pubDate></item><item><title>Integrating multi-source data and machine learning to Decipher the psoriasis-COPD comorbidity.</title><link>https://www.psoriasis-news.de/articles.html/1_articles/integrating-multi-source-data-and-machine-learning-to-decipher-the-psoriasis-copd-comorbidity-r473/</link><description><![CDATA[<small>No abstract supplied.</small><p><a href="http://europepmc.org/article/MED/41653319?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">473</guid><pubDate>Sun, 22 Feb 2026 17:52:44 +0000</pubDate></item><item><title>Depressive symptoms and psoriasis: Domain-specific associations in national cohorts.</title><link>https://www.psoriasis-news.de/articles.html/1_articles/depressive-symptoms-and-psoriasis-domain-specific-associations-in-national-cohorts-r472/</link><description><![CDATA[<h4>Background</h4>Psoriasis is frequently accompanied by depression. However, the role of specific symptom domains, including cognitive-affective and somatic symptoms, as well as potential metabolic mediators between psoriasis and depression, remains unclear.<h4>Methods</h4>We analyzed data from the National Health and Nutrition Examination Survey (NHANES, n = 14,964) and the Health and Retirement Study (HRS, n = 4364). Depressive symptoms were classified into cognitive-affective and somatic domains. Cross-sectional associations were evaluated in NHANES, and longitudinal symptom trajectories were identified in HRS using group-based trajectory modeling. Based on genome-wide association study summary statistics, bidirectional and two-step Mendelian randomization (MR) were performed to assess causality and identify plasma metabolite mediators.<h4>Results</h4>In NHANES, total depressive symptoms (OR = 1.03, 95% CI: 1.01-1.06, P = 0.018) and somatic symptoms (OR = 1.08, 95% CI: 1.03-1.12, P = 0.003) showed positive associations with psoriasis, but not cognitive-affective symptoms. In HRS, persistently high trajectories of total (OR = 1.58, 95% CI: 1.08-2.32, P = 0.018) was associated with psoriasis, with no significant association for the cognitive-affective and somatic domains after full adjustment. MR supported a causal relationship of psoriasis on depression and identified sphingomyelin (d17:2/16:0, d18:2/15:0) and urate as mediators, accounting for 10.2% and 6.8% of the total effect, respectively.<h4>Conclusion</h4>Depressive symptoms were linked to psoriasis in both cross-sectional and longitudinal analyses. Lipid and antioxidant-related pathways involving sphingomyelin and urate may mediate the relationship between psoriasis and depression, offering potential targets for intervention.<p><a href="http://europepmc.org/article/MED/41692049?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">472</guid><pubDate>Sun, 22 Feb 2026 17:52:44 +0000</pubDate></item><item><title>IL-23 Inhibitors in Psoriasis: What Have We Learnt so Far?</title><link>https://www.psoriasis-news.de/articles.html/1_articles/il-23-inhibitors-in-psoriasis-what-have-we-learnt-so-far-r471/</link><description><![CDATA[Interleukin-23 (IL-23) inhibitors represent a major advance in the management of moderate-to-severe plaque psoriasis, grounded in the central pathogenic role of the IL-23/Th17 axis. By selectively targeting the p19 subunit, guselkumab, risankizumab, and tildrakizumab effectively suppress disease-driving inflammation while preserving IL-12-mediated host defence. Pivotal randomized trials have demonstrated high levels of skin clearance, durable efficacy, and favourable safety profiles. Nevertheless, such trials only partially reflect the heterogeneous and medically complex populations treated in everyday practice. Against this background, this narrative review focuses on the expanding body of real-world evidence, which has provided novel insights into the long-term durability, drug survival, performance in difficult-to-treat anatomical sites, and safety of IL-23 inhibitors in special and comorbid populations. Real-world studies consistently confirm high effectiveness in elderly patients, individuals with multiple comorbidities, and those with extensive prior biologic exposure, as well as in challenging disease localisations such as scalp, nails, palmoplantar, genital, and pretibial psoriasis. Across large observational cohorts, IL-23 inhibitors show excellent treatment persistence, largely driven by sustained efficacy and low rates of discontinuation for adverse events. Reassuring safety profiles have also been documented in patients with a history of malignancy, latent infections, or cardiometabolic disease, together with improvements in quality of life and systemic inflammatory burden. By integrating evidence from randomized trials with large real-world cohorts, this narrative review provides a clinically oriented synthesis of the efficacy, safety, and therapeutic positioning of IL-23 inhibitors in psoriasis. Although all three agents demonstrate high and durable effectiveness, real-world data suggest subtle intraclass differences, with guselkumab and risankizumab often achieving faster or deeper early responses, and tildrakizumab offering greater dosing flexibility with comparable long-term persistence in selected patient profiles. Overall, IL-23 blockade has evolved from a highly effective trial-based strategy into a versatile and reliable long-term therapeutic approach capable of addressing unmet needs in routine clinical practice.<p><a href="http://europepmc.org/article/MED/41709961?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">471</guid><pubDate>Sun, 22 Feb 2026 17:52:44 +0000</pubDate></item><item><title>Pharmacokinetic-pharmacodynamic modelling of risankizumab using chronic plaque psoriasis real-world data.</title><link>https://www.psoriasis-news.de/articles.html/1_articles/pharmacokinetic-pharmacodynamic-modelling-of-risankizumab-using-chronic-plaque-psoriasis-real-world-data-r470/</link><description><![CDATA[<h4>Aim</h4>Risankizumab is a high-cost biologic treatment for chronic plaque psoriasis, an immune-mediated inflammatory disease presenting with painful red scaly skin lesions. Inter-individual heterogeneity in treatment response may be better addressed with personalised rather than fixed dosing. We sought to develop a pharmacokinetic/pharmacodynamic (PK/PD) model to characterise the relationship between risankizumab exposure and treatment response.<h4>Methods</h4>A sequential population PK/PD model was developed using real-world data (UK Biomarkers of Systemic Treatment Outcomes in Psoriasis study) comprising serial PK and Psoriasis Area and Severity Index (PASI) measures. Models were built using R (V4.3.1) and nlmixr2 (V2.1.1.9). One and two-compartment PK models were tested. A maximal effect turnover model was used to describe PASI, with drug effect on lesion development rate (K<sub>in</sub>).<h4>Results</h4>The dataset (82 serum risankizumab concentrations; 101 PASI observations) comprised 50 patients with psoriasis (median weight 79.3 kg; age 47 years). PK data were described by a one-compartment model with first-order absorption/elimination. Absorption rate (K<sub>a</sub>) was fixed from the literature (0.229). Estimated clearance was 0.34 L/day, and volume of distribution 12.9 L. Baseline PASI at model initiation, drug potency (EC<sub>50</sub>) and lesion recovery rate (K<sub>out</sub>) were estimated at 23.4, 0.11 mg/L and 0.05 day<sup>-1</sup>, respectively.<h4>Conclusions</h4>Pharmacokinetic parameters were similar to risankizumab clinical trials. K<sub>out</sub> estimates aligned with other psoriasis turnover models, highlighting the capture of disease dynamics that may be applied across drugs. This model may inform personalised dosing based on individual patient characteristics, drug exposure and response, to optimise treatment outcomes.<p><a href="http://europepmc.org/article/MED/41692695?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">470</guid><pubDate>Sun, 22 Feb 2026 17:38:20 +0000</pubDate></item><item><title>Psoriasis beyond the skin: systemic inflammation as a bridge to metabolic and hepatic comorbidities.</title><link>https://www.psoriasis-news.de/articles.html/1_articles/psoriasis-beyond-the-skin-systemic-inflammation-as-a-bridge-to-metabolic-and-hepatic-comorbidities-r469/</link><description><![CDATA[Psoriasis, long thought to be a chronic immune-mediated dermatological disease, is now being reclassified as a systemic inflammatory disease with substantial metabolic and hepatic complications. Psoriasis affects approximately 2-3% of global population and is associated with up to 50% risk of systemic comorbidities. This mini-review examines the evolving understanding of psoriasis pathogenesis, focusing on the interaction of immunological dysregulation, keratinocyte hyperproliferation, and systemic cytokine release. Tumour necrosis factor- alpha (TNF)-α, IL-17, IL-23, and IL-6 are pro-inflammatory mediators that cause cutaneous plaque formation and reach the systemic circulation, leading to insulin resistance, atherogenesis, and liver inflammation. The review identifies common immuno-metabolic pathways, including TNF-α/NF-κB activation, the IL-23/Th17 axis, and dysregulated PI3K/Akt/mTOR signalling, that contribute to psoriatic illness and associated disorders like metabolic syndrome and metabolic dysfunction-associated steatotic liver disease (MASLD). Epidemiological studies demonstrate that psoriasis patients have a high prevalence of obesity, type 2 diabetes, dyslipidaemia, regardless of established risk factors, supporting the updated classification of NAFLD as MASLD. These findings lend support to the idea that psoriasis is a multi-organ disease caused by chronic low-grade inflammation. Clinically, this requires a transition from skin-centred treatment to thorough systemic examination and customised, multidisciplinary management. Targeted biologic treatments, such as IL-17 and IL-23 inhibitors, offer potential for lowering both systemic inflammation and cutaneous symptoms. This review supports early screening, metabolic monitoring, and lifestyle changes as critical components of long-term psoriatic therapy. Recognising psoriasis as a systemic condition is critical for improving overall patient outcomes, lowering morbidity, and avoiding long-term consequences.<p><a href="http://europepmc.org/article/MED/41703364?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">469</guid><pubDate>Sun, 22 Feb 2026 17:38:20 +0000</pubDate></item><item><title>Survey on the management and patient satisfaction levels in individuals with psoriasis and/or psoriatic arthritis.</title><link>https://www.psoriasis-news.de/articles.html/1_articles/survey-on-the-management-and-patient-satisfaction-levels-in-individuals-with-psoriasis-andor-psoriatic-arthritis-r468/</link><description><![CDATA[Dear Editor, Psoriasis is a chronic, immune-mediated inflammatory dermatosis that affects approximately 3% of the adult population and exerts a substantial impact on health-related quality of life (QoL).

Guselkumab is approved in multiple countries worldwide, including the USA and those of the EU, for the treatment of adults with moderate-to-severe plaque psoriasis, active psoriatic arthritis, and moderately-to-severely active ulcerative colitis and Crohn's disease. In September 2025, guselkumab received its first pediatric approvals in the USA for the treatment of pediatric patients 6 years of age and older and weighing ≥ 40 kg who either have moderate-to-severe plaque psoriasis and are candidates for systemic therapy or phototherapy, or who have active psoriatic arthritis. Subsequently, guselkumab was approved in December 2025 in the EU for the treatment of moderate-to-severe plaque psoriasis in children and adolescents from the age of 6 years who are candidates for systemic therapy. Johnson &amp; Johnson is currently undertaking phase III development of guselkumab in pediatric patients with Crohn's disease and ulcerative colitis in various countries. This article summarizes the milestones in the development of guselkumab leading to these first pediatric approvals for plaque psoriasis and psoriatic arthritis.<p><a href="http://europepmc.org/article/MED/41697593?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">467</guid><pubDate>Sun, 22 Feb 2026 17:38:20 +0000</pubDate></item><item><title>Persistence and Long-Term Disease Control of Interleukin-17 Inhibitors and Interleukin-23 Inhibitors in Patients with Psoriasis: A Nationwide Cohort Study in Japan.</title><link>https://www.psoriasis-news.de/articles.html/1_articles/persistence-and-long-term-disease-control-of-interleukin-17-inhibitors-and-interleukin-23-inhibitors-in-patients-with-psoriasis-a-nationwide-cohort-study-in-japan-r466/</link><description><![CDATA[<h4>Introduction</h4>Interleukin-17 inhibitors (IL-17i) and interleukin-23 inhibitors (IL-23i) are advanced therapeutic options for moderate-to-severe psoriasis. In real-world settings, biologic persistence is commonly used as a proxy for effectiveness and safety, and a treatment-free status following biologic discontinuation may provide insights into disease remission. This study aimed to assess persistence and treatment-free status for IL-17i versus IL-23i among biologic-naïve patients with psoriasis in Japan.<h4>Patients and methods</h4>This retrospective cohort study analyzed data from the Japanese Medical Data Vision database from 01 January 2015 to 31 December 2022. Patients diagnosed with psoriasis who initiated IL-17i or IL-23i during this study period were included. Persistence of the index biologic and post-discontinuation treatment-free status were assessed using Kaplan-Meier methodology. Propensity score methods with inverse probability of treatment weighting and matching were employed to control potential confounding between treatment cohorts.<h4>Results</h4>There were 1,751 and 1,721 patients included in the IL-17i cohort and IL-23i cohort, respectively. Persistence rates for IL-17i were 55.7% [95% CI 53.2-58.1%] at the first year and 21.5% [95% CI 18.9-24.2%] at the fourth year, versus 77.7% [95% CI 75.4-79.8%] and 47.8% [95% CI 42.2-53.2%], respectively, for IL-23i. The risk of discontinuation of IL-23i was half that of IL-17i (adjusted hazard ratio [aHR]=0.49 [95% CI 0.44-0.54]). After discontinuation, 19.2% [95% CI 16.1-22.4%] and 31.5% [95% CI 27.8-41.2%] of patients in the IL-17i and IL-23i cohorts, respectively, remained treatment-free for at least 1 year. Patients treated with IL-23i had a lower risk for resuming systemic therapy after biologic discontinuation (aHR=0.57 [95% CI 0.49-0.67]).<h4>Conclusion</h4>IL-23i was associated with longer persistence and a longer post-discontinuation treatment-free period than IL-17i in patients with psoriasis. These findings may provide actionable insights for healthcare providers and patients as they develop treatment strategies. Future research integrating comprehensive clinical data is warranted to evaluate different treatment strategies, thereby informing clinical decision-making.<p><a href="http://europepmc.org/article/MED/41710906?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">466</guid><pubDate>Sun, 22 Feb 2026 17:38:20 +0000</pubDate></item><item><title>Ixekizumab for the treatment of psoriatic arthritis: an Italian multicentric retrospective observational study.</title><link>https://www.psoriasis-news.de/articles.html/1_articles/ixekizumab-for-the-treatment-of-psoriatic-arthritis-an-italian-multicentric-retrospective-observational-study-r465/</link><description><![CDATA[<small>No abstract supplied.</small><p><a href="http://europepmc.org/article/MED/41714331?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">465</guid><pubDate>Sun, 22 Feb 2026 17:38:20 +0000</pubDate></item><item><title>Development and validation of a prediction model for the risk of relapse in psoriasis</title><link>https://www.psoriasis-news.de/articles.html/1_articles/development-and-validation-of-a-prediction-model-for-the-risk-of-relapse-in-psoriasis-r464/</link><description><![CDATA[Abstract  <p>Background  This study collected and analyzed clinical data from patients with psoriasis, developing and validating a risk prediction model for psoriasis relapse. The aim is to improve the efficiency and accuracy of early screening for psoriasis relapse in clinical practice and to provide a reference for implementing preventive measures. Objective  To develop and validate a risk prediction model for psoriasis relapse. Methods  A convenience sampling method was used to select 504 psoriasis patients admitted to a tertiary hospital in China between January 2022 and December 2024, including 353 cases in the training set and 151 cases in the test set. Independent risk factors for psoriasis relapse were identified through univariate analysis and logistic regression analysis to develop a prediction model. A nomogram and SHAP summary plot were generated for model visualization, and the model’s goodness of fit and discriminative ability were evaluated. Results  The one-year relapse rate of psoriasis patients after treatment was 66.67%. Logistic regression analysis identified body mass index (BMI), diabetes, biologic agent use, smoking, upper respiratory tract infection (URTI), and non-standard medication as independent risk factors for psoriasis relapse, which were included in the model. The area under the ROC curve (AUC) values for the training and testing sets were 0.767 [95% CI: 0.715–0.818] and 0.704 [95% CI: 0.620–0.789], respectively. The model demonstrated good discrimination and calibration, and decision curve analysis (DCA) showed significant net benefit in both the training and testing sets. Conclusion  The psoriasis relapse risk prediction model developed in this study demonstrated good predictive performance. This model can serve as an effective reference for assessing the risk of psoriasis relapse and provides valuable insights for developing personalized prevention strategies for patients.</p><p><a href="http://europepmc.org/article/PPR/PPR1155393?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">464</guid><pubDate>Sun, 22 Feb 2026 17:38:20 +0000</pubDate></item><item><title>Nanocarriers for Psoriasis Treatment: Insights from a Clinical Trial Registered on the Global Clinical Trials Registry Platform.</title><link>https://www.psoriasis-news.de/articles.html/1_articles/nanocarriers-for-psoriasis-treatment-insights-from-a-clinical-trial-registered-on-the-global-clinical-trials-registry-platform-r463/</link><description><![CDATA[Psoriasis is a chronic, relapsing inflammatory skin disease. Topical treatments are the primary choice for up to 80% of psoriasis patients; however, their effectiveness is often limited by poor penetration into the skin. Nanocarriers represent a promising advancement in drug delivery systems by enhancing bioavailability and tissue penetration and reducing the frequency of dosing. This study conducted a narrative review and analyzed the characteristics of clinical trials registered on ClinicalTrials.gov and the International Clinical Trials Registry Platform (ICTRP) that investigated the use of nanocarriers for psoriasis treatment. The findings indicate that the proportion of registered randomized controlled trials (RCTs) focusing on nanocarriers for psoriasis treatment is exceedingly limited, comprising only 0.2% (11 out of 5338) of all registered RCTs related to psoriasis treatment. Among these 11 RCTs, six types of nanocarriers were identified: microemulsion/nanoemulsion, chitosan nanoparticles, liposomes, ethosomes, micelles, and niosomes. Five trials reported complete or partial outcomes using the Psoriasis Area and Severity Index (PASI) as the primary efficacy measure. However, many trials had incomplete baseline and follow-up PASI data. Studies have shown that encapsulating APIs within nanocarriers generally yields a more significant reduction in PASI scores than administering empty nanocarriers. Additionally, no study has directly compared nanocarriers with traditional formulations. The APIs used in these RCTs primarily comprised lipophilic drugs. In conclusion, although nanocarriers for psoriasis treatment demonstrate significant potential, they continue to face challenges, including incomplete regulatory frameworks, difficulties in large-scale production, and high production costs.<p><a href="http://europepmc.org/article/MED/41710365?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">463</guid><pubDate>Sun, 22 Feb 2026 17:38:20 +0000</pubDate></item><item><title>Observation on The Formation of Neutrophil Extracellular Traps in Psoriatic Peripheral Blood</title><link>https://www.psoriasis-news.de/articles.html/1_articles/observation-on-the-formation-of-neutrophil-extracellular-traps-in-psoriatic-peripheral-blood-r462/</link><description><![CDATA[Abstract  <p>Objective  To explore the clinical application value of Neutrophil extracellular traps (NETs) in evaluating psoriasis. Methods  2ml peripheral blood of 63 patients with psoriasis and 27 healthy controls were collected. Neutrophils were isolated by density gradient method, and the formation of NETs was observed by immunofluorescence staining. We then calculated the proportion and fluorescence intensity of NETs and analyzed their correlation with clinical classification, severity, and serological indicators. Furthermore, the skin lesions of 5 patients with psoriasis were collected, and the NETs were observed by immunofluorescence method. Results  The proportion and fluorescence intensity of spontaneous NETs in patients with psoriasis were significantly higher than those in healthy controls and were positively correlated with the PASI scores. The generation of NETs in psoriasis patients with metabolic syndrome (MetS) or high-TNF-α was higher than in psoriasis patients without metabolic abnormalities or normal-TNF-α. NETs were also observed in most psoriatic skin specimens. Conclusions  The levels of NETs are correlated with the disease severity of psoriasis and patients with metabolic abnormalities and may be used as a clinical indicator to reflect the inflammatory state of psoriasis and metabolic comorbidity of psoriasis for disease evaluation.</p><p><a href="http://europepmc.org/article/PPR/PPR1155392?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">462</guid><pubDate>Sun, 22 Feb 2026 17:38:20 +0000</pubDate></item><item><title>Psychological Well-Being of Patients with Moderate-to-Severe Plaque Psoriasis Treated with Tildrakizumab: 28-Week Interim Results from a Multicenter Observational Study in Italy Using the DASS-21 Questionnaire, the BLUE Study.</title><link>https://www.psoriasis-news.de/articles.html/1_articles/psychological-well-being-of-patients-with-moderate-to-severe-plaque-psoriasis-treated-with-tildrakizumab-28-week-interim-results-from-a-multicenter-observational-study-in-italy-using-the-dass-21-questionnaire-the-blue-study-r461/</link><description><![CDATA[<h4>Introduction</h4>Psoriasis is a chronic inflammatory skin disease associated with significant physical and psychological burden. Tildrakizumab, an interleukin-23 p19 inhibitor, has demonstrated efficacy in treating moderate-to-severe plaque psoriasis both in clinical trials and real-world setting. However, limited data are available on the impact of the effective treatment of psoriasis on the psychological health of patients. The aim of this study was to assess changes in psychological well-being, as well as clinical and quality-of-life outcomes, in patients with moderate-to-severe plaque psoriasis treated with tildrakizumab in routine clinical practice in Italy.<h4>Methods</h4>This was an interim analysis (IA) of a 52-week multicenter, prospective, observational study. Adults with moderate-to-severe plaque psoriasis initiating tildrakizumab were enrolled. Endpoints focused on well-being and psychological health and included changes, from baseline to week 28, in Depression, Anxiety, and Stress Scale-21 (DASS-21) scores, Dermatology Life Quality Index (DLQI), European Social Survey (ESS) items, and World Health Organization-Five Well-Being Index (WHO-5). Effectiveness was also monitored via Psoriasis Area and Severity Index (PASI), and safety via treatment-emergent adverse event reporting.<h4>Results</h4>A total of 115 patients were included (mean age 52.5 years, 60.8% male), 102 receiving ≥ 1 dose of tildrakizumab and completing DASS-21 evaluations at baseline and week 28. At week 28, improvements were observed in DASS-21 subscales [depression (- 2.6, 95% CI - 2.0 to - 1.0), anxiety (- 2.3, 95% CI - 2.0 to - 1.0), and stress (- 3.4, 95% CI - 4.0 to - 2.0)], accompanied by marked PASI reduction (- 13.7, 95% CI - 12.8 to - 10.1). DLQI, ESS, and WHO-5 scores also improved. Adverse events were generally mild or moderate, with no unexpected safety signals.<h4>Conclusion</h4>In this real-world IA, tildrakizumab was observed to improve the psychological well-being of patients, reflected by a reduction in all items of the DASS-21 scale and, in parallel, confirmed its effectiveness in managing physical symptoms of psoriasis, establishing its role in the holistic management of psoriasis.<p><a href="http://europepmc.org/article/MED/41712057?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">461</guid><pubDate>Sun, 22 Feb 2026 17:38:20 +0000</pubDate></item><item><title>Exploring the risk association between psoriasis and chronic obstructive pulmonary disease, and asthma using the NHIS database.</title><link>https://www.psoriasis-news.de/articles.html/1_articles/exploring-the-risk-association-between-psoriasis-and-chronic-obstructive-pulmonary-disease-and-asthma-using-the-nhis-database-r459/</link><description><![CDATA[<h4>Background</h4>Asthma (AS) and chronic obstructive pulmonary disease (COPD) are prevalent chronic airway disorders with shared inflammatory pathways. Considering the systemic inflammatory nature of psoriasis, this study utilized the National Health Interview Survey (NHIS) to investigate its potential association with COPD and AS.<h4>Methods</h4>Data from the 2023 NHIS were analyzed, with participants selected based on specific inclusion criteria. A baseline table was constructed, and multivariate logistic regression models, along with risk stratification analysis, were employed to examine the correlations between psoriasis and COPD and AS. Receiver operating characteristic (ROC) analysis was conducted to assess the predictive value for both conditions.<h4>Results</h4>A total of 27,106 participants were included in the study. Significant differences were observed in the baseline characteristics of psoriasis, age, race, region, gender, education, marital status, employment, income, smoking habits, health status, mental health, disability, heart attack history, BMI, prediabetes, cancer, hypertension, hypercholesterolemia, arthritis, coronary heart disease, stroke, health insurance, anxiety, and depression (P &lt; 0.001). Multivariate logistic regression revealed a strong association between psoriasis and COPD (model 1: OR 2.63, 95% CI: 2.13-3.23, P &lt; 0.001; model 2: OR 2.43, 95% CI: 1.95-2.99, P &lt; 0.001; model 3: OR 1.54, 95% CI: 1.21-1.96, P &lt; 0.001). A similar association was found between psoriasis and AS (model 1: OR 1.68, 95% CI: 1.42-1.97, P &lt; 0.001; model 2: OR 1.74, 95% CI: 1.47-2.05, P &lt; 0.001; model 3: OR 1.32, 95% CI: 1.11-1.56, P &lt; 0.01). The ROC analysis based on model 3 demonstrated substantial predictive power of psoriasis for COPD, with an AUC of 0.881.<h4>Conclusion</h4>Psoriasis was identified to have a strong association with COPD and AS, which provided valuable insights into understanding the pathogenesis of these diseases.<p><a href="http://europepmc.org/article/MED/41686756?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">459</guid><pubDate>Sun, 22 Feb 2026 17:23:03 +0000</pubDate></item><item><title>Investigating the role of serum human beta defensin-2 in psoriasis and psoriatic arthritis: a case-control study on hBD-2 and CRP, ESR.</title><link>https://www.psoriasis-news.de/articles.html/1_articles/investigating-the-role-of-serum-human-beta-defensin-2-in-psoriasis-and-psoriatic-arthritis-a-case-control-study-on-hbd-2-and-crp-esr-r458/</link><description><![CDATA[<h4>Introduction</h4>Human beta-defensin 2 (hBD-2) is an antimicrobial peptide upregulated by IL-17A and TNF-α, important in skin immunity and inflammation. While hBD-2 is elevated in psoriatic skin, its systemic expression and clinical significance remain unclear, particularly in psoriatic arthritis (PsA).<h4>Objectives</h4>To compare serum hBD-2 levels among patients with psoriasis vulgaris, PsA, and healthy controls, and to evaluate its correlation with disease severity and inflammatory markers.<h4>Methods</h4>This case-control study included 66 patients with psoriasis, 30 with PsA, and 67 healthy controls. Serum hBD-2, C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR) were measured. Psoriasis severity was assessed using the Psoriasis Area and Severity Index (PASI). A <i>p</i> value &lt; 0.05 was considered statistically significant.<h4>Results</h4>Median serum hBD-2 levels were significantly higher in psoriasis and PsA groups compared to controls (<i>p</i> &lt; 0.001), but no significant difference was found between the two patient groups (p: 0.223). In the psoriasis group, hBD-2 showed no significant correlation with PASI (r: 0.218, p: 0.095), CRP (r: 0.158, p: 0.277), or ESR (r: 0.129, p: 0.369). CRP and ESR were significantly higher in the PsA group than in other groups (<i>p</i> &lt; 0.001 and p: 0.002, respectively).<h4>Conclusions</h4>Although serum hBD-2 is elevated in psoriasis and PsA, it does not correlate with clinical or laboratory disease activity in psoriasis. These findings suggest that hBD-2 may reflect local cutaneous immune activation rather than systemic inflammation.<p><a href="http://europepmc.org/article/MED/41689371?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">458</guid><pubDate>Sun, 22 Feb 2026 17:23:03 +0000</pubDate></item></channel></rss>
