This study aims to gain insight in the perspectives of patients with psoriasis on this important subject.<b>Methods:</b> A cross-sectional questionnaire study including adult female and male patients with psoriasis, independent of their treatment type.<b>Results:</b> A total of 102 patients responded to the questionnaire (70% females, 30% males), of whom 47.1% have ever used biologic therapy. Respondents preferred dermatologists or general practitioners (GPs) as information provider. Patients would like to receive FPP information on fertility, heredity of psoriasis, use of psoriasis medication, and - specifically for females- the course of psoriasis during and after pregnancy and breastfeeding. Timing of FPP information provision was preferable at moment of diagnosis and medication changes or upon explicit request.<b>Conclusion:</b> Dermatologists and GPs have a crucial role in providing FPP information. The findings of this study have provided hands-on guidance for healthcare professionals to improve healthcare for both female and male patients with psoriasis in the reproductive age.<p><a href="http://europepmc.org/article/MED/40739803?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">167</guid><pubDate>Mon, 04 Aug 2025 07:43:04 +0000</pubDate></item><item><title>Greater topical corticosteroid quantity applied reduces severity of psoriasis: Results from two randomized controlled trials.</title><link>https://www.psoriasis-news.de/articles.html/1_articles/greater-topical-corticosteroid-quantity-applied-reduces-severity-of-psoriasis-results-from-two-randomized-controlled-trials-r166/</link><description><![CDATA[<h4>Background</h4>Topical drugs containing corticosteroids are recommended first-line treatment for patients with mild-moderate psoriasis. However, the optimal recommended dosage of topical drugs has not been well established.<h4>Objectives</h4>To investigate the effect of topical drug application quantity and treatment duration on psoriasis treatment outcome.<h4>Methods</h4>We conducted a post-hoc analysis of two randomized controlled trials investigating 214 patients with psoriasis using topical drugs containing corticosteroids and/or calcipotriol for up to 48 weeks. We measured the amount of topical drugs used during the study period and calculated the mean amount of applied drugs per 1% affected body surface area (BSA) divided by number of days in the study period. Improvement in severity of psoriasis was measured by Lattice-System Physician's Global Assessment (LS-PGA) (where affected BSA was divided into seven categories) from baseline to last study visit. Descriptive results were reported as counts with proportions, and as means with normality-based confidence intervals (CI). Associations were analyzed using linear regressions.<h4>Results</h4>Most study participants had a duration of psoriasis greater than 20 years, moderate psoriasis, and no history of using systemic psoriasis treatment. They had applied a mean of 1.0 g per 1% BSA per day (95% CI 0.9; 1.2). Daily use of topical drugs for four-weeks reduced severity of psoriasis. However, extended daily use for up to 48 weeks provided further reduction in disease severity (coefficient --0.30 (95% CI -0.51, -0.09)) and -0.73 (95% CI -1.09; -0.38) (P= 0.028). Greater amount of applied topical drugs reduced severity of psoriasis in a linear manner. Every increase of 1 g of topical drugs applied per 1% BSA per day reduced LS-PGA by 0.43 (95% CI 0.24; 0.61). Finally, patients who had never used systemic drugs experienced a greater reduction in psoriasis when applying the same mean amount of topical drugs (coefficient -0.7 (95% CI -1.1, -0.4) compared to those who had a history of taking systemic treatment (-0.3 (95% CI -0.5; -0.1), P=0.026).<h4>Conclusions</h4>A mean application amount of at least 1.0 g of topical drugs per 1% BSA per day seems safe and effective and can be used daily until clearance.<p><a href="http://europepmc.org/article/MED/40737510?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">166</guid><pubDate>Mon, 04 Aug 2025 07:43:04 +0000</pubDate></item><item><title>Apremilast in Psoriasis: Current Landscape and Perspectives.</title><link>https://www.psoriasis-news.de/articles.html/1_articles/apremilast-in-psoriasis-current-landscape-and-perspectives-r165/</link><description><![CDATA[Psoriasis is an immune-mediated skin disease manifested in more than 3% of Americans and over 125 million people worldwide. The inflammatory skin condition with an increased rate of keratinocyte turnover involves every level of the skin and exhibits various forms of the disease, including plaque, guttate, inverse, pustular, and erythrodermic psoriasis, as well as disease-associated conditions, such as psoriatic arthritis and nail psoriasis. Innovative treatment has highlighted the importance of Apremilast, an oral drug that belongs to the phosphodiesterase- 4 (PDE4) class, which was approved by the FDA in 2014. Apremilast works by increasing the presence of cyclic adenosine monophosphate (cAMP) within cells, thereby affecting inflammatory processes and reducing the production of pathological cytokines. Randomized controlled trials have shown that it effectively treats moderately to severely affected plaque psoriasis and psoriatic arthritis, and it is safer than traditional systemic agents. The new perspective on the usage of ethosomes, niosomes, liposomes, and nanostructured lipid carriers in psoriasis treatment is based on emerging nanotechnology in drug delivery systems. These new formulations are designed to enhance the solubility and targeted release of Apremilast, thus providing an enhanced therapeutic effect. This review will discuss the basic mechanisms of the disease known as psoriasis, as well as the mode of operation, pharmacological properties, clinical trials, and pharmacokinetics of apremilast, particularly in relation to nanocarrier modification of this promising drug.<p><a href="http://europepmc.org/article/MED/40739686?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">165</guid><pubDate>Mon, 04 Aug 2025 07:43:04 +0000</pubDate></item><item><title>Therapeutic Potential of Mesenchymal Stem Cells in Psoriasis.</title><link>https://www.psoriasis-news.de/articles.html/1_articles/therapeutic-potential-of-mesenchymal-stem-cells-in-psoriasis-r164/</link><description><![CDATA[Psoriasis is a chronic immune-mediated disease mainly affecting the skin with different clinical manifestations. As patients with psoriasis may also suffer from psoriatic arthritis and the skin lesions of psoriasis are disfiguring, their quality of life is often impaired. Many environmental and genetic factors have been implicated in psoriasis development. Currently, there is no cure for the disease and long-term drug treatment is usually necessary, especially in moderate to severe cases. Mesenchymal stem cells (MSCs) are popular candidates for cell-based treatment in many immune-mediated diseases due to their ability to secrete a wide array of cytokines and growth factors and their immunomodulatory properties. MSCs from various sources administered via different routes have been shown to ameliorate psoriasis. This review gives an overview of psoriasis and MSCs and examine preclinical and clinical studies concerning the application of MSCs in the treatment of psoriasis, as well as consolidate major findings in this area of research.<p><a href="http://europepmc.org/article/MED/40748586?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">164</guid><pubDate>Mon, 04 Aug 2025 07:43:04 +0000</pubDate></item><item><title>Copay Accumulators: A Legislative Issue in Dermatology.</title><link>https://www.psoriasis-news.de/articles.html/1_articles/copay-accumulators-a-legislative-issue-in-dermatology-r163/</link><description><![CDATA[<small>No abstract supplied.</small><p><a href="http://europepmc.org/article/MED/40741379?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">163</guid><pubDate>Mon, 04 Aug 2025 07:43:04 +0000</pubDate></item><item><title>Real-World Effectiveness and Safety of Risankizumab in Psoriasis: A Comprehensive Analysis from the Saudi Arabia Psoriasis Registry (PSORSA).</title><link>https://www.psoriasis-news.de/articles.html/1_articles/real-world-effectiveness-and-safety-of-risankizumab-in-psoriasis-a-comprehensive-analysis-from-the-saudi-arabia-psoriasis-registry-psorsa-r154/</link><description><![CDATA[<h4>Introduction</h4>Psoriasis is a chronic immune-mediated skin condition that has a substantial impact on patients' quality of life. The Saudi Arabia Psoriasis Registry (PSORSA) was established to address long-term real-world data (RWD) on systemic and biologic therapies in the region. This observational cohort study provides a comprehensive analysis of baseline disease characteristics, comorbidities, and treatment efficacy among patients enrolled in PSORSA, with an emphasis on risankizumab.<h4>Methods</h4>Data were sourced from a governmental online database covering multiple healthcare centers. Patients eligible for biologics were followed at baseline and at weeks 16, 28, 40, and 52 to evaluate disease severity, quality of life, and adherence. Statistical analyses were conducted using Jamovi and R. Descriptive statistics were performed for categorical and continuous variables. p-Values &lt; 0.05 were considered significant.<h4>Results</h4>The study cohort included 313 patients. Plaque psoriasis was the most prevalent clinical type (93.9%). An analysis of treatment history revealed that 39.6% of patients had prior therapy exposure, and all patients received risankizumab as a biologic therapy. At baseline, the mean Psoriasis Area and Severity Index (PASI) score was 25.49. By week 52, it had decreased to 0.358, indicating complete clearance. PASI scores showed a steady and substantial reduction over time, with an 88% reduction at week 16, 96% at week 28, 97.5% at week 40, and 98.5% by week 52, demonstrating a strong and sustained treatment effect (p &lt; 0.001). Additionally, risankizumab exhibited a favorable drug survival profile, with many patients maintaining treatment beyond 122 weeks.<h4>Conclusion</h4>This study represents the first real-world assessment of risankizumab for moderate-to-severe psoriasis in Saudi Arabia. The findings demonstrate that risankizumab is an effective and well-tolerated treatment for moderate-to-severe psoriasis in this Saudi Arabian cohort. However, future studies should explore long-term safety outcomes and the comparative effectiveness of risankizumab and emerging biologics in diverse patient populations.<p><a href="http://europepmc.org/article/MED/40711523?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">154</guid><pubDate>Thu, 31 Jul 2025 12:43:37 +0000</pubDate></item><item><title>Biologic and small molecule therapies for psoriasis in individuals with Down syndrome: Two cases and a systematic review.</title><link>https://www.psoriasis-news.de/articles.html/1_articles/biologic-and-small-molecule-therapies-for-psoriasis-in-individuals-with-down-syndrome-two-cases-and-a-systematic-review-r153/</link><description><![CDATA[Down syndrome (DS), also known as trisomy 21, is a genetic condition linked to a higher prevalence of skin disorders, including psoriasis, which affects up to 8% of individuals. DS patients with psoriasis present unique management considerations, including a theoretical increased risk of infectious complications with immunosuppressive therapies. This report includes two cases and a systematic review summarizing available evidence on psoriasis characteristics and treatment outcomes in individuals with DS. We report two DS patients with psoriasis demonstrating variable therapeutic responses: one controlled with acitretin and another requiring secukinumab after multiple treatment failures. To contextualize these findings, we conducted a systematic review following PRISMA guidelines, identifying 10 studies comprising 37 DS patients with psoriasis. Methotrexate was the most frequently failed therapy. Biologics targeting IL-17 and IL-23 pathways achieved the highest rates of complete resolution. These findings reflect Th1/Th17-driven inflammation in DS and highlight the need for individualized, pathway-specific management strategies.<p><a href="http://europepmc.org/article/MED/40717838?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">153</guid><pubDate>Thu, 31 Jul 2025 12:43:37 +0000</pubDate></item><item><title>Correction to "Impact of Delay of Treatment With Disease-Modifying Antirheumatic Drugs in Psoriatic Arthritis: The CorEvitas Psoriatic Arthritis/Spondyloarthritis Registry".</title><link>https://www.psoriasis-news.de/articles.html/1_articles/correction-to-impact-of-delay-of-treatment-with-disease-modifying-antirheumatic-drugs-in-psoriatic-arthritis-the-corevitas-psoriatic-arthritisspondyloarthritis-registry-r152/</link><description><![CDATA[<small>No abstract supplied.</small><p><a href="http://europepmc.org/article/MED/40728028?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">152</guid><pubDate>Thu, 31 Jul 2025 12:43:37 +0000</pubDate></item><item><title>A Validated Quantitative LC-MS/MS Method for Determination of Deucravacitinib in Rat Plasma and Its Application to a Pharmacokinetic Study.</title><link>https://www.psoriasis-news.de/articles.html/1_articles/a-validated-quantitative-lc-msms-method-for-determination-of-deucravacitinib-in-rat-plasma-and-its-application-to-a-pharmacokinetic-study-r151/</link><description><![CDATA[We developed and validated a novel analytical methodology for the precise quantification of deucravacitinib, an oral TYK2 inhibitor for treating moderate-to-severe plaque psoriasis in adults. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) was employed in this method for sensitive detection of the compound in rat plasma. Analytical separation was performed utilizing an ACE C18 column (4.6 × 100 mm, 5-μm particle size) with a carefully optimized mobile phase composition of methanol and 2-mM ammonium formate (90:10, v/v), maintained at a consistent flow rate of 0.9 mL/min. Detection was executed in positive ionization mode, targeting multiple reaction monitoring (MRM) transitions of m/z 426.8 → 358.4 for the analyte and m/z 394.1 → 363.2 for the internal standard. The validation of the analytical method encompassed an assessment of selectivity, linearity, accuracy, precision, recovery, and stability. This method demonstrated stability, specificity, and no matrix effect at three concentration levels (1.606, 267.600, 507.780 ng/mL). The method's lower limit of quantification (LLOQ) is 0.556 ng/mL. The calibration curve demonstrates linearity from the LLOQ up to 668.132 ng/mL, exhibiting a high correlation coefficient (r<sup>2</sup> = 0.9976). The intraday and interday precisions were less than 6.62% and 5.95%, respectively, with accuracies ranging from 90.68% to 103.80%. The recovery of deucravacitinib ranged from 95.34% to 103.80% and remained stable under different conditions. After successful validation, the method was used for pharmacokinetic profiling of deucravacitinib in rats following oral administration.<p><a href="http://europepmc.org/article/MED/40695726?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">151</guid><pubDate>Thu, 31 Jul 2025 12:43:37 +0000</pubDate></item><item><title>Greater topical corticosteroid quantity applied reduces severity of psoriasis: Results from two randomized controlled trials.</title><link>https://www.psoriasis-news.de/articles.html/1_articles/greater-topical-corticosteroid-quantity-applied-reduces-severity-of-psoriasis-results-from-two-randomized-controlled-trials-r150/</link><description><![CDATA[Topical drugs containing corticosteroids are recommended first-line treatment for patients with mild-moderate psoriasis.

The effects of this treatment on skin microorganisms and microbiome-encoded metabolic pathways remain unclear.<h4>Objectives</h4>This was an exploratory clinical study designed to investigate whether Psoriasis is associated with skin microbiota, as well as a longitudinal cohort study aimed at revealing the effects of IL-17A inhibitor treatment on skin microbiota in Psoriasis.<h4>Methods</h4>In this study, we recruited 26 patients with moderate to severe psoriasis and 15 healthy controls. We collected skin microbiome samples from both greasy and dry skin regions. All samples were analyzed using 16S rDNA gene sequencing to determine the microbial profiles.<h4>Results</h4>Compared with healthy controls, the composition and function of skin microbiome in psoriasis patients are heterogeneous. Treatment with IL-17A inhibitors significantly increases the alpha diversity of the skin microbiota in psoriasis patients, indicating potential restoration of microbial community richness and evenness. However, this treatment does not entirely alter the taxonomic composition of the skin microbiota; rather, it shifts the relative abundance of specific microbial species, indicating that certain core microbial features remain relatively stable. Moreover, IL-17A inhibitors help adjust the functional profile of the skin microbiome in psoriasis patients, bringing it closer to that of healthy individuals.<h4>Conclusions</h4>Psoriasis patients exhibit significant heterogeneity in both the composition and functionality of their skin microbiota. Although IL-17A inhibitor treatment fails to fundamentally alter its taxonomic composition, this therapy effectively enhances microbial community stability by increasing alpha diversity and modulating the relative abundance of various taxa. Additionally, it adjusts the functional profile of the skin microbiota towards a healthier state, thereby contributing to the restoration of microecological balance.<p><a href="http://europepmc.org/article/MED/40708005?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">149</guid><pubDate>Thu, 31 Jul 2025 12:43:37 +0000</pubDate></item><item><title>Successful Treatment with Secukinumab in a Psoriasis Patient on Hemodialysis.</title><link>https://www.psoriasis-news.de/articles.html/1_articles/successful-treatment-with-secukinumab-in-a-psoriasis-patient-on-hemodialysis-r148/</link><description><![CDATA[Moderate to severe psoriasis has been reported as an independent risk factor for IgA nephropathy (IgAN). IgAN is characterized by episodic microscopic hematuria, which can progress to end-stage renal disease (ESRD). Managing therapeutic interventions for psoriasis patients requiring dialysis due to ESRD presents significant challenges. We present a case of severe plaque psoriasis in a patient concurrently diagnosed with IgAN who is dependent on hemodialysis. Over the past two months, his condition has worsened without any identifiable triggers. Physical examination revealed generalized scaly plaques on the scalp, trunk, and extremities, resulting in a Psoriasis Area Severity Index (PASI) score of 19.2. Laboratory tests confirmed end-stage renal insufficiency, with no other abnormalities detected. Consequently, the patient was prescribed subcutaneous secukinumab following a standard regimen. He achieved complete resolution of symptoms after eight weeks of treatment and experienced no recurrence during a one-year follow-up. His kidney-related parameters remained stable during secukinumab therapy. To summarize, this case report discusses a patient with severe psoriasis who also has concurrent IgAN and ESRD, successfully treated with secukinumab. It reinforces the rapid efficacy and enduring safety of secukinumab in managing psoriasis in hemodialysis-dependent patients with IgAN comorbidity. Zeno Fratton et al has reported that an interleukin (IL)-17A/F inhibitor effectively treats moderate-to-severe psoriasis in patients with chronic kidney disease (CKD). However, further studies are necessary to develop evidence-based guidelines for biologic selection within this vulnerable population.<p><a href="http://europepmc.org/article/MED/40718360?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">148</guid><pubDate>Thu, 31 Jul 2025 12:43:37 +0000</pubDate></item><item><title>Copay Accumulators: A Legislative Issue in Dermatology</title><link>https://www.psoriasis-news.de/articles.html/1_articles/copay-accumulators-a-legislative-issue-in-dermatology-r147/</link><description><![CDATA[<small>No abstract supplied.</small><p><a href="http://europepmc.org/article/PMC/PMC12303918?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">147</guid><pubDate>Thu, 31 Jul 2025 12:43:37 +0000</pubDate></item><item><title>Treatment of severe psoriasis in a hospice care patient using secukinumab, an inhibitor of interleukin-17A expression: Treatment response and changes in quality of life.</title><link>https://www.psoriasis-news.de/articles.html/1_articles/treatment-of-severe-psoriasis-in-a-hospice-care-patient-using-secukinumab-an-inhibitor-of-interleukin-17a-expression-treatment-response-and-changes-in-quality-of-life-r146/</link><description><![CDATA[Secukinumab, a fully human monoclonal antibody that antagonizes interleukin-17A (IL-17A), has proven efficacious in the management of moderate to severe plaque psoriasis. Secukinumab has established itself as an effective treatment for plaque psoriasis, offering rapid and sustained symptom improvement. However, more research is warranted to assess its efficacy and safety in elderly patients, where clinical data is currently lacking. We describe an 84-year-old female presented with stable angina pectoris needed to be hospice cared. She had more than 30 years history of plaque psoriasis. The patient underwent treatment with secukinumab for two weeks. The skin lesions had been decreased rapidly and this greatly improved quality life of this patient. We report the clinical use of secukinumab in the treatment of elderly psoriasis and biologicals may be a new strategy for hospice care of patients with psoriasis.<p><a href="http://europepmc.org/article/MED/40329840?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">146</guid><pubDate>Thu, 31 Jul 2025 12:43:37 +0000</pubDate></item><item><title>Correction to &#x201C;Impact of Delay of Treatment With Disease&#x2010;Modifying Antirheumatic Drugs in Psoriatic Arthritis: The CorEvitas Psoriatic Arthritis/Spondyloarthritis Registry&#x201D;</title><link>https://www.psoriasis-news.de/articles.html/1_articles/correction-to-impact-of-delay-of-treatment-with-disease%E2%80%90modifying-antirheumatic-drugs-in-psoriatic-arthritis-the-corevitas-psoriatic-arthritisspondyloarthritis-registry-r145/</link><description><![CDATA[<small>No abstract supplied.</small><p><a href="http://europepmc.org/article/PMC/PMC12305346?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">145</guid><pubDate>Thu, 31 Jul 2025 12:43:37 +0000</pubDate></item><item><title>Recent advancement of fisetin-based nanoformulations in the management of psoriasis.</title><link>https://www.psoriasis-news.de/articles.html/1_articles/recent-advancement-of-fisetin-based-nanoformulations-in-the-management-of-psoriasis-r143/</link><description><![CDATA[Psoriasis is a chronic inflammatory autoimmune skin disease with enhanced skin cell turnover. Despite the therapies currently available, better and target-oriented therapies are needed. Fisetin is a flavonoid with antioxidant, anti-inflammatory, and immunomodulatory properties. It shows therapeutic potential, but its poor bioavailability and penetration into the skin cannot be used effectively to treat psoriasis. While fisetin-loaded nanoformulations in cancer and other diseases have been explored, their potential as a therapy for psoriasis is unexplored. Most reviews detail the biological activities of fisetin or nanoformulations for psoriasis therapy but not their combination. The review here compiles fisetin's chemical and pharmacological properties along with the problems with conventional drug delivery and fisetin-loaded nanoformulations such as polymeric nanoparticles, liposomes, solid lipid nanoparticles, nanogels, and micelles. It also discusses their mechanisms, preclinical results, and potential for the clinic. Preclinical studies demonstrate fisetin nanoformulations to enhance penetration into the skin, reduce inflammation, promote skin regeneration in psoriasis models, and alleviate symptoms of redness and scaling. Clinical trials are lacking, and studies are needed to assess safety and efficacy. Fisetin nanoformulations are a potential target-oriented psoriasis therapy with better drug delivery and fewer side effects than conventional therapies. Despite formulation stability, scalability, and regulatory issues, the potential for fisetin-loaded nanoformulations is excellent and needs further exploration for their safety and efficacy in patients.<p><a href="http://europepmc.org/article/MED/40622453?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">143</guid><pubDate>Sat, 12 Jul 2025 18:34:11 +0000</pubDate></item><item><title>Neutrophil Extracellular Trap (NET) Markers in Psoriasis: Linking with Disease Severity and Comorbidities.</title><link>https://www.psoriasis-news.de/articles.html/1_articles/neutrophil-extracellular-trap-net-markers-in-psoriasis-linking-with-disease-severity-and-comorbidities-r142/</link><description><![CDATA[Psoriatic patients have shown higher levels of neutrophil extracellular traps (NETs) vs healthy controls. Psoriasis is often associated with other comorbidities such as cardiovascular disease. An increase in indirect markers of NETs has been found in patients with increased cardiovascular events in patients without psoriasis.We conducted a prospective observational study with psoriatic patients. A total of 39 of patients were included. Myeloperoxidase, neutrophil elastase and double-stranded DNA were significantly higher in patients with severe-to-moderate vs mild psoriasis. Myeloperoxidase was also significantly higher in patients of moderate high vs low cardiovascular risk (p = .01) in patients with mild psoriasis. Patients with psoriatic arthritis show higher myeloperoxidase levels higher vs those without arthritis (p = .048). Myeloperoxidase was also significantly correlated (p = .0375) with the patients' BMI.The detection of NETs through indirect markers (Myeloperoxidase, neutrophil elastase and double-stranded DNA) is associated with the severity of psoriasis.

This study introduces a novel approach leveraging deep learning and numerical simulations of skin biomechanical properties to enhance diagnostic precision. By utilizing ABAQUS software, this study incorporates 1000 numerical simulations for data generation to combat the limitations of datasets in these ailments. Utilizing the ResNet-50 convolutional neural network (CNN), this research integrates data from finite element simulations based on variations in skin's biophysical parameters. The dataset comprises 1000 instances, evenly divided between Psoriasis and Lichen Planus, with attributes including displacement, humidity, age, and sex. The numerical data were converted into image data to optimize the ResNet-50 model's performance. The results were validated through 5-fold cross-validation, 3-fold cross-validation, and random splitting. The proposed methodology demonstrated remarkable diagnostic accuracy, achieving 99.8% using 5-fold cross-validation, surpassing previous investigations, and highlighting the potential of combining AI and biomechanical simulations for real-time skin disease diagnosis to assist physicians and dermatologists in classifying skin diseases.<p><a href="http://europepmc.org/article/MED/40610543?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">141</guid><pubDate>Sat, 12 Jul 2025 18:34:11 +0000</pubDate></item><item><title>Moving beyond the Janus kinase signaling kinases in the pathogenesis and treatment of psoriasis and psoriatic arthritis.</title><link>https://www.psoriasis-news.de/articles.html/1_articles/moving-beyond-the-janus-kinase-signaling-kinases-in-the-pathogenesis-and-treatment-of-psoriasis-and-psoriatic-arthritis-r140/</link><description><![CDATA[Psoriatic disease encompasses psoriasis and psoriatic arthritis. It is a chronic, progressive condition and leads to irreversible joint destruction. Conventional treatments used are disease-modifying antirheumatic drugs and biologics. Janus kinase (JAK) signal transducers and activators of transcription (STAT) cell signaling protein inhibitors have shown promising results in psoriatic disease. However, JAK inhibitors have been associated with some concerning safety issues, such as cardiac risks, venous thrombotic episodes, malignancy, and infection. There are other developing molecules beyond JAK inhibitors, such as tyrosine kinase 2 (TYK2) inhibitors, RAR-related orphan receptor gamma (RORγ) inhibitors, mammalian target of rapamycin inhibitors, nerve growth factor inhibitors, and STAT kinase inhibitors. In this narrative review, we have discussed such molecular targets beyond JAK inhibitors to examine their role in the treatment of psoriatic disease. This review discusses the potential of these new options, particularly TYK2 inhibitors, which is already Food and Drug Administration approved for psoriasis. These advancements offer promising options for the management of psoriatic disease.<p><a href="http://europepmc.org/article/MED/40627989?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">140</guid><pubDate>Sat, 12 Jul 2025 18:34:11 +0000</pubDate></item><item><title>Exploring the relationship between novel measurements of abdominal obesity and psoriasis: a cross-sectional study from the NHANES database.</title><link>https://www.psoriasis-news.de/articles.html/1_articles/exploring-the-relationship-between-novel-measurements-of-abdominal-obesity-and-psoriasis-a-cross-sectional-study-from-the-nhanes-database-r139/</link><description><![CDATA[<h4>Background</h4>Psoriasis is a chronic skin disease affecting millions of people, with obesity being a common comorbidity. Many studies suggest that obesity may influence the onset and treatment efficacy of psoriasis. Currently, increasing evidence indicates that abdominal obesity is associated with various metabolic diseases, but research on the relationship between abdominal obesity and psoriasis remains limited. This study uses advanced obesity indicators such as the conicity index and body roundness index to explore the association between abdominal obesity and psoriasis.<h4>Methods</h4>This study is a cross-sectional analysis that uses univariate regression analysis and weighted multivariable logistic regression to investigate the relationship between conicity index, android percent fat, body roundness index, and psoriasis. Additionally, restricted cubic spline analysis was performed to explore the nonlinear association between these indicators and psoriasis. Subgroup analysis and interaction tests were also conducted.<h4>Results</h4>A total of 4873 participants were included in this study. After adjusting for confounding variables, the results showed a positive correlation between conicity index, android percent fat, body roundness index, and the risk of psoriasis. When conicity index, android percent fat, and body roundness index were converted into quartiles (Q1-Q4), the risk of psoriasis in the Q4 group was significantly higher compared to the Q1 group (conicity index: p = 0.032, android percent fat: p = 0.020, body roundness index: p = 0.003). In the subgroup analysis and interaction tests, no significant interaction between the conicity index, body roundness index, and the association with psoriasis was found (p &gt; 0.05). The results only suggest that the poverty income ratio (PIR), marital status, and alcohol consumption may influence the relationship between android percent fat and psoriasis. In addition, subgroup analysis based on age shows that the association between abdominal obesity and psoriasis is more significant in the population over 40 years old.<h4>Conclusions</h4>After adjusting for covariates, the study found that three abdominal obesity indicators-conicity index, android percentage fat, and body roundness index-are positively correlated with psoriasis risk, suggesting that the association between abdominal obesity and psoriasis as a comorbidity is more likely to occur, emphasizing the clinical significance of this link.<h4>Level of evidence</h4>Level III, Evidence obtained from well-designed cohort or case-control analytic studies.<p><a href="http://europepmc.org/article/MED/40616714?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">139</guid><pubDate>Sat, 12 Jul 2025 18:34:11 +0000</pubDate></item><item><title>Trace Elements and Risk of Immune-Mediated Skin Disease: A Systematic Review and Meta-analysis.</title><link>https://www.psoriasis-news.de/articles.html/1_articles/trace-elements-and-risk-of-immune-mediated-skin-disease-a-systematic-review-and-meta-analysis-r138/</link><description><![CDATA[<h4>Context</h4>Evidence regarding the relationship between serum trace element levels and immune-mediated inflammatory skin diseases (IMSDs) is inconsistent.<h4>Objective</h4>In this systematic review and meta-analysis we aimed to evaluate the association between selected serum trace element levels (zinc [Zn], copper [Cu], iron [Fe], selenium [Se], and calcium [Ca]) and IMSDs (psoriasis, vitiligo, atopic dermatitis [AD], alopecia areata [AA], hidradenitis suppurativa, and bullous diseases).<h4>Data sources</h4>We conducted a comprehensive search on the PubMed, EMBASE, Scopus, China National Knowledge Infrastructure, and Web of Science databases from the database inception date to May 2, 2024. Studies measuring serum, plasma, or whole-blood levels of Zn, Cu, Fe, Se, or Ca in patients with IMSD compared to those in healthy controls were included.<h4>Data extraction</h4>This study followed the guidelines of the Meta-analysis of Observational Studies in Epidemiology and the Preferred Reporting Items for Systematic Review and Meta-analyses guidelines. Two authors (X.Y.S. and Y.O.) independently reviewed the titles and abstracts of the identified studies using a standardized collection form.<h4>Data analysis</h4>The primary outcome was the standardized mean difference with a 95% CI in serum trace element levels (Zn, Cu, Fe, Se, and Ca) between patients with IMSDs and healthy controls. Overall, 113 studies involving 7014 patients with IMSD were included in the meta-analysis. Compared with those in the healthy control group, serum Zn levels decreased in patients with vitiligo, psoriasis, and AA; serum Cu levels increased in patients with psoriasis, AD, and AA; serum Se and Fe levels decreased in patients with psoriasis and AD.<h4>Conclusion</h4>Serum trace element levels showed more significant changes in patients with IMSDs than in healthy controls. These findings suggest that alterations in trace element levels may be associated with the occurrence, development, and prognosis of IMSDs.<p><a href="http://europepmc.org/article/MED/40036807?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">138</guid><pubDate>Sat, 12 Jul 2025 18:34:11 +0000</pubDate></item><item><title>Association between Polycyclic Aromatic Hydrocarbon Metabolites and Psoriasis in US Adults: Evidence from the National Health and Nutrition Examination Survey.</title><link>https://www.psoriasis-news.de/articles.html/1_articles/association-between-polycyclic-aromatic-hydrocarbon-metabolites-and-psoriasis-in-us-adults-evidence-from-the-national-health-and-nutrition-examination-survey-r137/</link><description><![CDATA[<h4>Background</h4>Polycyclic aromatic hydrocarbons (PAHs) are environmental pollutants with widespread human exposure and have been associated with adverse health outcomes. However, their potential relationship with psoriasis remains insufficiently explored.<h4>Objective</h4>The aim of this study is to investigate the association between PAH exposure and psoriasis.<h4>Methods</h4>Data were obtained from the National Health and Nutrition Examination Survey (NHANES) for the periods 2005-2006, 2009-2010, and 2011-2012. Weighted multivariate logistic regression analysis was performed to assess the association between individual PAH metabolites and psoriasis. Bayesian kernel machine regression (BKMR), quantile g-computation (qgcomp), and weighted quantile sum (WQS) regression were used to evaluate the relationship between mixed PAH exposure and psoriasis, as well as to determine the relative contributions of specific PAH metabolites. Stratified and sensitivity analyses were conducted to assess result stability.<h4>Results</h4>A total of 4,912 participants (mean age, 43.52 years; 95% CI, 42.65-44.39 years) were included, of whom 2,514 (51.18%) were female, and 141 (2.87%) were diagnosed with psoriasis. Multivariate logistic regression analysis identified significant positive associations between psoriasis and seven urinary PAH metabolites: 2-hydroxynaphthalene, 3-hydroxyfluorene, 2-hydroxyfluorene, 3-hydroxyphenanthrene, 1-hydroxyphenanthrene, 2-hydroxyphenanthrene, and 1-hydroxypyrene. Analysis of mixed exposure PAH across all three models demonstrated significant positive associations between urinary PAH metabolites and psoriasis, with 2-hydroxyphenanthrene and 2-hydroxynaphthalene identified as primary contributors. Stratified and sensitivity analyses confirmed the robustness of these results, and the observed associations persisted among non-smokers.<h4>Conclusion</h4>Both single and mixed exposure analyses demonstrated a positive association between PAH exposure and psoriasis. These findings suggest that reducing PAH exposure may help mitigate psoriasis risk.<p><a href="http://europepmc.org/article/MED/40639344?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">137</guid><pubDate>Sat, 12 Jul 2025 18:34:11 +0000</pubDate></item><item><title>Global Guidelines for Psoriatic Arthritis Management: A Comparative Analysis.</title><link>https://www.psoriasis-news.de/articles.html/1_articles/global-guidelines-for-psoriatic-arthritis-management-a-comparative-analysis-r136/</link><description><![CDATA[<h4>Background</h4>Psoriatic arthritis (PsA) is a complex immune-mediated heterogeneous inflammatory disease. Treatment decisions are challenging given the multisystem involvement. To further guide management strategies, we conducted a comparative analysis of the latest global guidelines highlighting the contrast in their approach to treat different PsA domains.<h4>Methods</h4>Major global guidelines for PsA management were reviewed, including American College of Rheumatology 2018 update, European Alliance of Associations for Rheumatology 2023 update, British Society of Rheumatology 2022, Group for Research and Assessment of Psoriasis and Psoriatic Arthritis 2021, and Pan American League of Associations for Rheumatology 2024.<h4>Results</h4>The guidelines unanimously recommend a treat-to-target strategy with a focus on active PsA. Divergence existed in treatment sequencing regarding the use of biologic and targeted disease-modifying antirheumatic drugs (DMARDs). Variations were also noted in the management of enthesitis and dactylitis. Addressing comorbidities and associated conditions is regarded to be a cornerstone for optimizing disease control and preventing flares.<h4>Conclusion</h4>This review highlights the different management strategies among the global guidelines. Furthermore, we pointed at promising new therapeutic targets that are likely to be incorporated into future recommendations.<p><a href="http://europepmc.org/article/MED/40635364?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">136</guid><pubDate>Sat, 12 Jul 2025 18:34:11 +0000</pubDate></item><item><title>Validation of patient-reported outcome measures for dactylitis, psoriatic skin and nail disease, and uveitis in patients with psoriatic arthritis in routine care.</title><link>https://www.psoriasis-news.de/articles.html/1_articles/validation-of-patient-reported-outcome-measures-for-dactylitis-psoriatic-skin-and-nail-disease-and-uveitis-in-patients-with-psoriatic-arthritis-in-routine-care-r135/</link><description><![CDATA[<h4>Background</h4>In routine care, Danish patients with psoriatic arthritis are monitored in the DANBIO registry. In March 2022, patient-reported outcome measures (PROMs) on selected non-musculoskeletal manifestations (NMM) were implemented.<h4>Aim</h4>To validate PROMs for current dactylitis, skin and nail psoriasis, and recent uveitis in patients with psoriatic arthritis.<h4>Methods</h4>Adaptive cross-sectional study. Patients in the rheumatologic clinic answered PROMs with 'yes'/'no'/'do not know' and assessed the extent of skin psoriasis and number of dactylitis-affected digits in DANBIO. PROM entries were compared with the physician's assessments (physical examination, review of patient file), with the physician being the gold standard. With 134 patients included, 20% had incorrectly reported dactylitis; therefore, a dactylitis photo was added to the PROM. Sensitivity, specificity, positive and negative predictive values, accuracy and Cohen's kappa were calculated. Level of agreement for dactylitis count was explored by Bland-Altman plot. From patient 200, the physician was blinded to PROs.<h4>Results</h4>We included 300 patients (51% female, median age=55 years), with a median disease duration of 8 years, where 43% received biologic treatment. According to the physician's assessment, 41 (14%) patients had current dactylitis, 164 (55%) psoriasis, 163 (54%) nail psoriasis and 3 (1%) recent uveitis. For the dactylitis PROM, the sensitivity/specificity/Cohen's kappa was 0.89/0.81/0.57, psoriasis 1.0/0.94/0.95, nail psoriasis 0.76/0.94/0.66 and uveitis 1.00/0.99/0.59. Agreement on psoriasis extent was 90%. Patient-reported dactylitis count was on average 1.0 unit higher than physician-reported but decreased to 0.7 after adding the dactylitis photo. Results were similar irrespective of blinding.<h4>Conclusion</h4>Patients reliably self-report dactylitis, psoriasis, and uveitis and the PROMs are valuable for monitoring NMMs in routine care.<p><a href="http://europepmc.org/article/MED/40617585?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">135</guid><pubDate>Sat, 12 Jul 2025 18:34:11 +0000</pubDate></item><item><title>A case report of genital psoriasis following transgender vaginoplasty</title><link>https://www.psoriasis-news.de/articles.html/1_articles/a-case-report-of-genital-psoriasis-following-transgender-vaginoplasty-r134/</link><description><![CDATA[<small>No abstract supplied.</small><p><a href="http://europepmc.org/article/PMC/PMC12245232?source=rss" rel="external nofollow">Weiterlesen</a></p>]]></description><guid isPermaLink="false">134</guid><pubDate>Sat, 12 Jul 2025 18:34:11 +0000</pubDate></item></channel></rss>
