Introduction Psoriasis is a chronic immune-mediated disease with significant systemic implications. Tildrakizumab, an IL-23p19 inhibitor, has demonstrated efficacy in moderate-to-severe plaque psoriasis. Higher doses may be beneficial for patients with elevated body weight or greater disease burden. This study evaluates the effectiveness of tildrakizumab 200 mg in a real-world setting, analyzing outcomes based on weight, Psoriasis Area Severity Index (PASI), body mass index (BMI), and prior biol

Unregulated herbal supplements can pose significant health risks due to undisclosed ingredients. Tawon Liar, an Indonesian product marketed as an "all-natural" remedy, claims to alleviate pain and boost immunity but lacks stringent regulatory oversight. We report a unique case of Tawon Liar-induced Immunoglobulin A (IgA) vasculitis and exacerbation of psoriasis, highlighting the potential dangers associated with misadvertised supplements. A 53-year-old migrant worker from Mexico with a history o

Psoriasis has been linked to various diet-related comorbidities such as metabolic syndrome, type 2 diabetes, and cardiovascular disease. Evidence is lacking on the role of diet in the management of psoriasis and its comorbidities. We aimed to characterise the dietary patterns and quality of diet in individuals living with psoriasis and to assess whether psoriasis severity and comorbidities are associated with diet quality. Using the UK Biobank cohort, individuals identified with psoriasis via se

Psoriasis is an immune-mediated chronic inflammatory disease. Increasing evidence suggests a close association between ribosome biogenesis (RiboSis) and the pathogenesis of psoriasis. However, the precise mechanisms remain unclear. We first obtained bulk transcriptome and single-cell RNA sequencing datasets from the GEO database. Subsequently, differential expression analysis (DEG) and weighted gene co-expression network analysis (WGCNA) were performed, preliminarily identifying 11 candidate bio

Psoriasis pathogenesis involves dysregulated immune responses, yet the role of protein prenylation (particularly PGGT1B-mediated geranylgeranylation) in macrophage-driven inflammation remains poorly understood. This study aims to explore the role and molecular mechanism of protein geranylgeranyltransferase type I subunit beta (PGGT1B) in the development of psoriasis. Myeloid cell-specific PGGT1B gene knockout mice were generated, and a mouse psoriasis model was established with imiquimod to stud

Background/Objectives: Psoriasis is a chronic inflammatory skin disease increasingly linked to psychiatric and behavioral comorbidities, including depression, anxiety, and substance use disorders. Shared inflammatory pathways, including elevated IL-6, TNF-α, and IL-17, may link psoriasis with psychiatric disorders such as depression and anxiety. The bidirectional interaction between systemic inflammation and mental health may exacerbate the disease burden and affect treatment outcomes. The objec

Abstract Objective: We aimed to identify and characterize distinct subgroups of patients with psoriatic arthritis (PsA) based on their responses to the Assessment of SpondyloArthritis International Society Health Index (ASAS HI), using latent class analysis (LCA). Methods: We performed a latent class analysis on 17 dichotomous ASAS HI items in a cohort of patients with PsA (n: 90). A Gaussian mixture model was applied, and the optimal number of classes was selected based on the Akaike (AIC) and

Background Psoriasis is a chronic inflammatory skin condition driven by immune dysregulation, significantly diminishing patients' quality of life. The advent of targeted biological therapies and small molecule inhibitors has transformed the treatment landscape for moderate-to-severe Psoriasis. Nevertheless, there remains a scarcity of comparative efficacy and safety data between these therapeutic classes, highlighting the need for a systematic review to evaluate their relative performance.Object

To describe the design and methodology of APACHE, a cohort of patients with early peripheral psoriatic arthritis (pPsA), and to assess the main baseline clinical characteristics of the first included patients. APACHE is an ongoing prospective multicentre national cohort (NCT03768271) with a planned follow-up of 10 years. Included patients have recent-onset (<12 months) peripheral arthritis, a personal and/or family history of psoriasis, pPsA diagnosed by a rheumatologist, and no history of ta

Immune-mediated inflammatory diseases (IMIDs), such as psoriasis, psoriatic arthritis, and inflammatory bowel disease, encompass a heterogenous group of conditions associated with chronic inflammation. Systemic treatments for patients with IMIDs include parenterally delivered monoclonal antibodies (mAbs) that disrupt specific cytokine and cytokine receptor binding interactions, and orally delivered small molecules that inhibit certain enzymes involved in the regulation of inflammatory signaling.

Generalized pustular psoriasis (GPP) is a potentially life-threatening infrequent immune-mediated disease characterized by rapid-onset of erythematous plaques, sterile pustules, and systemic inflammation. Spesolimab, a monoclonal antibody targeting the interleukin-36 receptor, is a novel treatment for GPP. However, GPP's low incidence and limited evidence represents a challenge in determining its real-world efficacy. This review aims to explore the clinical use of spesolimab in a real-world sett

Background Psoriatic arthritis (PsA) is an immune-mediated chronic inflammatory disease that causes chronic pain, psychological problems, and a significant economic burden, and therefore must be diagnosed and treated early. Existing treatments have limited efficacy and side effects. The study aimed to identify potential drug targets associated with psoriatic arthritis through proteomics and Mendelian randomization (MR) analysis.Materials and methods Large-scale genome-wide association studies an

Background The correlation between psoriasis with individual cardiometabolic diseases (CMDs), including coronary heart disease (CHD), stroke, hypertension, heart failure (HF), and type 2 diabetes mellitus (T2DM), have yielded conflicting results, and genetic susceptibility's role in modifying these relationships remains unexplored.Objective To investigate the association of psoriasis with the risk of CMDs, and to assess the modified effect of genetic susceptibility on these associations.Methods

Background Psoriasis is an immune-mediated skin disease where Th17 cell differentiation and IL-17 secretion play critical roles. This study investigates key exosomal ncRNAs regulating the Th17/IL-17 axis in psoriasis and their mechanisms.Methods We integrated bulk RNA sequencing datasets from the GEO database to construct and evaluate exosome-related patterns. Subsequently, exosome-related ncRNAs in psoriasis lesions were identified primarily through weighted gene co-expression network analysis

Background Psoriasis is a chronic disease with a prevalence of 3% in the general population. The high prevalence of psoriasis has prompted the study of its comorbidities in recent decades. However, no studies have ever analyzed comorbidity patterns including all chronic diseases in psoriatic patients.Objectives To identify comorbidity patterns in psoriatic patients using network analysis and describe them from a clinical point of view.Methods We conducted an observational and retrospective study

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

Psoriasis is a persistent immune-mediated inflammatory dermatosis. The treatment of psoriasis now features natural medicine as an effective new alternative because of its notable effectiveness and few side effects. Nervonic acid (NA), a long-chain fatty acid mostly sourced from the seed oils of some wild plants, exhibits significant antidepressant and anti-inflammatory properties. Nonetheless, the pathogenic effects and mechanism of NA in the pathogenesis of psoriasis are unreported. This work d

Ethnopharmacological relevance Psoriasis is a chronic immune-mediated skin disease characterized by the infiltration of multiple inflammatory cells and abnormal differentiation of keratinocytes in the skin. The treatment of psoriasis is primarily based on immunosuppressive drugs; however, their long-term use can lead to various adverse effects. Euphorbia humifusa Willd. (EuH) is used in traditional Chinese medicine for its anti-inflammatory properties and effects on skin diseases such as psorias

Background Psoriasis skin lesions are generally thought to occur before psoriatic arthritis (PsA) develops. However, PsA may be challenging to diagnose in the absence of psoriasis and might be underdiagnosed when occurring before psoriasis. We tested the hypothesis that PsA may commonly occur before psoriasis, but without psoriasis skin lesions, is diagnosed as another form of arthritis.Methods A single-center retrospective chart review was performed to identify patients with qualifying diagnose

Introduction SB17 is a ustekinumab (UST) biosimilar targeting interleukin-12/23 for treating immune-mediated inflammatory diseases (IMIDs). The development of UST biosimilars like SB17 may help address the high cost of innovator biologics, offering affordable alternatives without compromising efficacy or safety.Areas covered This review encompasses the totality of evidence supporting SB17's similarity to UST, its regulatory approval, and indication extrapolation. It also discusses SB17's lower i

Psoriasis is a significant global health challenge due to limited treatment efficacy. Paris saponin VII (PSVII) shows anti-inflammatory and anti-proliferative potential but its role in psoriasis is unclear. In this study, PSVII was identified from a library of natural compounds as a therapeutic candidate for psoriasis. In a murine model, PSVII reduced skin lesion severity, epidermal thickness, and inflammatory factor expression, preliminaryly indicating its anti-inflammatory properties. In vitro

Background Psoriasis and psoriatic arthritis are chronic autoimmune inflammatory conditions frequently associated with a range of comorbidities, including oncological diseases. Managing these conditions in patients with a history of cancer requires careful consideration of treatment efficacy and safety. Apremilast, an oral phosphodiesterase 4 (PDE4) inhibitor, has shown promise in the treatment of psoriasis and psoriatic arthritis. However, data on its use in oncological patients remain limited.

The Psoriasis Area and Severity Index (PASI) is widely used to evaluate psoriatic disease activity in clinical settings; however, its limitations hinder its practicality in routine use. The Simple-Measure for Assessing Psoriasis Severity (S-MAPA) has emerged as a promising tool addressing these limitations, providing a more feasible approach for assessing disease severity. This study aimed to evaluate the S-MAPA as a sensitive and practical alternative to existing instruments for measuring psori

Moderate to severe psoriasis is often treated with systemic medications, including traditional therapies (eg, methotrexate, cyclosporine) and biologics (eg, TNF inhibitors, IL-17 and IL-23 inhibitors). These immunomodulating treatments raise concerns about infection risks, particularly during the SARS-CoV-2 pandemic. However, literature on systemic therapy and COVID-19 outcomes in the United States is limited. This retrospective cohort study analyzed adults with psoriasis and a primary SARS-CoV-

Background Nail psoriasis (NP) is not an uncommon psoriasis variant whose symptoms have a negative impact on patients' quality of life. Treating NP can be a great challenge for the dermatologist, especially when it is presented as isolated subtype or when it is not associated with psoriatic arthritis (PsA). The available treatments, topical or systemic therapies, have limited efficacy and can be associated with adverse effects (AEs). Topical roflumilast is an FDA-approved treatment for skin plaq
