Introduction Palmoplantar pustulosis (PPP) is a chronic, recurrent, inflammatory disease and assumed to be a subtype of psoriasis. Pustular psoriasis (PP) is a chronic inflammatory disease that is further subclassified into various entities with different presentations including generalized pustular psoriasis (GPP) and palmoplantar pustular psoriasis (PPPP). Given the central role of the JAK-STAT pathway in cytokine signaling, this systematic review evaluated the effectiveness and safety of Janu

Psoriasis is a chronic immune-mediated skin disorder characterized by excessive keratinocyte proliferation, inflammation, and oxidative stress. This study investigates the role of the JNK/c-Jun cascade in psoriasis pathogenesis, focusing on its impact on keratinocyte proliferation and inflammatory responses. An in vitro psoriasis model was established using M5-stimulated HaCaT keratinocytes, while an in vivo model was created with imiquimod-treated Wistar rats. The results indicated that M5 stim

Background Although testing for latent tuberculosis (TB) infection has been standard practice for psoriasis patients being treated with IL-17 or IL-23 inhibitors, evidence for this practice is weak.Objectives To review evidence on safety of IL-17 and IL-23 inhibitors in the setting of latent TB infection, and to provide a new Joint Position Statement on this topic.Methods Experts from the National Psoriasis Foundation (NPF) and the International Psoriasis Council (IPC) reviewed evidence regardin

Inflammatory monocytes are increasingly recognized as key amplifiers of psoriasis, yet the epigenetic drivers of their pathogenic signature remain unclear. Here, we demonstrate that the histone demethylase KDM6B is markedly upregulated and catalytically active in classical monocytes during the imiquimod (IMQ)-induced psoriasis model. This is associated with reduced levels of the repressive histone mark H3K27me3, an epigenetic modification linked to chromatin compaction and transcriptional silenc

Abstract In the context of psoriasis lesion segmentation, traditional methods in image segmentation, including region-based approaches like Mask R-CNN, have shown notable success. However, the problem of segmenting irregular and intricate biological structures such as psoriasis lesions presents significant challenges that cannot be effectively captured by standard bounding box approximations. This paper explores the potential of transforming psoriasis lesion segmentation into pixel labeling tas

Psoriasis, the most common inflammatory skin disease, is marked by excessive proliferation of keratinocytes and infiltration of immune cells into the epidermis. Current treatments, particularly biologics targeting the IL‑23/IL‑17 axis, demonstrate excellent efficacy, but issues of recurrence and side effects persist. Therefore, it is essential to identify safer and more effective alternatives. Lobetyolin (LBT), a key component of polyacetylenes in Codonopsis pilosula, exhibits potent antioxidant

Abstract Psoriasiform adverse cutaneous reactions to immune checkpoint inhibitor (ICI) therapy for cancer are potentially treatment-limiting. Few studies have investigated long-term outcomes related to exacerbations of pre-existing psoriasis and their impact on the efficacy of cancer treatment. Understanding outcomes in patients with autoimmune disease is important to guide management of these reactions and avoid unnecessary exclusion from ICI therapy. We conducted a retrospective cohort study

Psoriasis burdens children and adults, but the impact of air pollution and aging is unclear. This study examines the association between air pollution exposure and psoriasis risk, considering the mediating role of biological aging. A prospective cohort study of 284,544 adults (51.3% female, mean age 56.26 ± 8.10 years) from the UK Biobank examined long-term exposure to air pollutants (PM2.5, PM10, PM2.5-10, NO2, and NOX). Biological aging was assessed using phenotypic age algorithms. Cox proport

Objective To evaluate the long-term efficacy of interleukin (IL)-17A inhibition with secukinumab on structural bone changes and clinical outcomes in psoriatic arthritis (PsA).Methods We conducted a phase-IV non-interventional study on adult patients with active PsA using high-resolution peripheral quantitative CT (HR-pQCT) and MRI of the hand over 48 months. All participants received secukinumab treatment and were followed up according to clinical practice, with repeated HR-pQCT and MRI. Number

Psoriasis is a relapsing autoimmune disease exacerbated by aberrant interleukin (IL)-17 A activity. Majoon Ushba, a unani polyherbal formulation implicated in clinical cases of psoriasis lacks immunopharmacological validation. The study aims to investigate the pre-clinical efficacy of Majoon Ushba and its therapeutic role in mitigating IL-17A-induced keratinocytes ferroptosis via ablation of JAK-2/STAT-3 pathway. HaCaT cells were stimulated with IL-17A to assess the activation of the JAK-2-STAT-

Introduction Psoriasis and obesity often occur together, with up to 50% of patients with psoriasis being classified as obese. This increases systemic inflammation, cardiovascular risk, and disease severity while reducing the efficacy of biologic treatments. Despite this overlap, dermatology lacks obesity-specific guidance. This review evaluates lifestyle, pharmacological (glucagon-like peptide 1 receptor agonists [GLP-1 RAs] and tirzepatide) and surgical strategies, as well as clinic-level algor

Introduction Psoriasis is a chronic disease and prevalent among 2-3% of the global population. Several therapeutic options alongside recent biologics have allowed the decrease and control of psoriasis lesions reaching a Psoriasis Area Severity Index (PASI) clearance of PASI75 or PASI90. Despite clinical improvements in lesions and provided PASI scores by clinicians as treatment success, patients have expressed varied satisfaction and perceptions. We present a case series that provides real-world

Background Psoriasis, a chronic inflammatory skin condition, poses significant management challenges due to its persistent nature, recurrences, and side effects associated with conventional therapies. Ayurveda correlates psoriasis with Ekakushtha (a type of skin disorder), primarily involving Vata-Kapha dosha imbalance.Objective To evaluate the efficacy of Ayurvedic therapies, including Shodhana (Vamana, Raktamokshana) and Shamana (pacification medications), in managing scalp psoriasis.Methodolo

Background Metabolic dysfunction-associated steatotic liver disease (MASLD) is more prevalent in patients with psoriasis compared to healthy individuals. Interleukin (IL)-17 and IL-23 inhibitors may have beneficial effects on MASLD by reducing systemic inflammation and improving metabolic parameters.Objectives To assess the effect of IL-17 and IL-23 inhibitors on MASLD and liver fibrosis in patients with psoriasis.Design We performed a systematic review that followed the Preferred Reporting Item

Psoriasis is a chronic inflammatory skin disease whose main manifestation is scaly and erythematous plaques. The pathogenesis is complex, including genetic and environmental factors. In recent years, epigenetic modifications, which means changing in gene expression instead of altering the DNA sequence, have been gradually studied by scholars as an important mechanism in psoriasis pathogenesis. The clinical application of epigenetics in psoriasis is promising with its potential as diagnostic biom

Rheumatoid arthritis (RA) is the most common inflammatory joint disease worldwide. T-cell inhibitors, tumor necrosis factor inhibitors, interleukin inhibitors (ILIs), Janus kinase inhibitors, and B-cell depletion therapy are indicated as second-line therapy and are prescribed for other inflammatory autoimmune conditions (ankylosing spondylitis, psoriatic arthritis, psoriasis, Crohn disease, ulcerative colitis) co-occurring in an estimated 7% to 20% of patients with RA but are routinely excluded

At the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) 2024 annual meeting, Drs. Dennis McGonagle and Wilson Liao discussed "MHC-I-opathies," a class of immune-mediated diseases genetically associated with major histocompatibility complex class I (MHC-I) and class I peptide processing. MHC-I-opathies demonstrate epistatic interactions, genetic associations, and immunopathology that are distinct from classic B cell and autoantibody-driven autoimmune diseases. Inves
